Answer:
21.5
Step-by-step explanation:
First we can solve for c using the pythagoreom theorem. (probably didn't spell that right)
A squared + B squared = C squared
9 squared + 3 squared = c squared
81+9= c squared
90=c squared
90 square root is (rounded to the nearest tenth) 9.5
c=9.5
Then we can add 9.5+9+3= 21.5

suppose you are playing poker with a non-standard deck of cards. the deck has 5 suits, each of which contains 12 values (so the deck has 60 cards total). how many 6-card hands are there, where you have at least one card from each suit?
Answers
The number of 6-card hands in which at least one card from each suit is equal to 8,184,220.
Total number of 6-card hands that can be formed from a deck of 60 cards is,
Using combination formula,
C(60, 6) = 50,063,860
Now, subtract the number of 6-card hands that do not contain at least one card from each suit.
There are 5 ways to choose the suit that will be missing from the hand.
Once this suit is chosen, there are 48 cards remaining in the other suits.
Choose 6 cards from this set, so the number of 6-card hands that do not contain any cards from the chosen suit is,
C(48, 6) = 12,271,512
Overcounted the number of hands that are missing more than one suit.
There are C(5, 2) ways to choose 2 suits that will be missing from the hand.
Once these suits are chosen, there are 36 cards remaining in the other 3 suits.
Choose 6 cards from this set, so the number of 6-card hands that do not contain any cards from the chosen suits is,
C(36, 6) = 1,947,792
We cannot have a 6-card hand that is missing more than 2 suits.
3 suits with no cards in the hand, which is not allowed.
Number of 6-card hands that have at least one card from each suit is,
C(60, 6) - 5×C(48, 6) + C(5, 2)×C(36, 6)
=50,063,860 - 5× 12,271,512 + 10 × 1,947,792
= 50,063,860 -61,357,560 + 19,477,920
= 8,184,220
Therefore, there are 8,184,220 of 6-card hands that have at least one card from each suit.

Point B is not the midpoint of line AC, because angle AOB is not half of angle AOC.
What is the value of angle AOB and angle BOC?If point B is the midpoint of line AC, then angle AOB must be equal to angle BOC.
The value of angle AOC is calculated as follows;
let angle AOC = θ
cos θ = 100 yds / 500 yds
cos θ = 0.2
θ = cos⁻¹ (0.2)
θ = 78.5⁰
The value of length AC is calculated as follows;
AC = √ (500² - 100²)
AC = 489.9
If point B is the midpoint, then AB = BC = 489.9/2 = 244.95
The value of angle AOB is calculated as follows;
tan β = AB/AO
tan β = 244.95/100
tan β = 2.4495
β = arc tan (2.4495)
β = 67.8⁰
Half of angle AOC = 78.5⁰/2 = 39.25⁰
β ≠ 39.25⁰
So point B is not midpoint of line AC, since angle AOB is not half of angle AOC.

I need help what is the approximate area, in square feet, of the shaded region in this figure use 3. 14
Answers
To find the approximate area of the shaded region in this figure, we need to subtract the area of the smaller circle from the area of the larger circle. The radius of the larger circle is 6 feet and the radius of the smaller circle is 3 feet.
The formula for the area of a circle is A = πr^2, where π is approximately 3.14 and r is the radius.
So, the area of the larger circle is A = 3.14 x 6^2 = 113.04 square feet.
The area of the smaller circle is A = 3.14 x 3^2 = 28.26 square feet.
To find the area of the shaded region, we subtract the area of the smaller circle from the area of the larger circle:
Area of shaded region = 113.04 - 28.26 = 84.78 square feet (rounded to two decimal places).

Use the Generalized Power Rule to find the derivative of the function.
f(x) = (3x + 1)^5(3x - 1)^6
Answers
This is the derivative of the given function f(x) = (3x + 1)^5(3x - 1)^6 using the Generalized Power Rule.
To find the derivative of the function f(x) = (3x + 1)^5(3x - 1)^6 using the Generalized Power Rule, we will need to apply both the Product Rule and the Chain Rule.
The Product Rule states that if you have a function f(x) = g(x)h(x), then f'(x) = g'(x)h(x) + g(x)h'(x).
First, let's identify g(x) and h(x) in your function:
g(x) = (3x + 1)^5
h(x) = (3x - 1)^6
Next, we'll find the derivatives g'(x) and h'(x) using the Chain Rule, which states that if you have a function y = [u(x)]^n, then y' = n[u(x)]^(n-1) * u'(x).
For g'(x):
u(x) = 3x + 1
n = 5
u'(x) = 3
g'(x) = 5(3x + 1)^(5-1) * 3 = 15(3x + 1)^4
For h'(x):
u(x) = 3x - 1
n = 6
u'(x) = 3
h'(x) = 6(3x - 1)^(6-1) * 3 = 18(3x - 1)^5
Now, we apply the Product Rule:
f'(x) = g'(x)h(x) + g(x)h'(x) = 15(3x + 1)^4(3x - 1)^6 + (3x + 1)^5 * 18(3x - 1)^5

A leaf blower was marked up 150% from an original cost of $80. Last Friday, Lee bought the leaf blower and paid an additional 7. 75% in sales tax. What was his total cost?
$
Answers
Lee's total cost for the leaf blower was $215.50.
First, let's find the selling price of the leaf blower before sales tax was added:
The leaf blower was marked up by 150%, so the selling price is:
= [tex]80 + (\frac{150}{100}) 80[/tex]
= 80 + 120
= 200
So the selling price of the leaf blower before sales tax was $200.
Next, we need to find the amount of sales tax that Lee paid. To do this, we need to multiply the selling price by the sales tax rate:
Sales tax = 7.75% ($200)
= 0.0775 ($200)
= $15.50
Finally, we can find Lee's total cost by adding the selling price and the sales tax:
Total cost = Selling price + Sales tax
= $200 + $15.50
= $215.50
Therefore, Lee's total cost for the leaf blower was $215.50.

Answers
If you paid $25,000 for your car and you sell it after owning the car for 3 years, then the worth of the car is t₃=$7,910. 15 (option c).
To find the value of your car after owning it for 3 years, we need to evaluate the function at t=3. This means we need to substitute t=3 into the function and simplify the expression.
f(3) = 0.75(3) = 2.25
The output of the function when t=3 is 2.25. But what does this number mean? It represents the fraction of the original value of the car that remains after owning it for 3 years.
To find the actual value of the car, we need to multiply this fraction by the original value of the car, which is given as $25,000.
Value of car after 3 years = 2.25 x $25,000 = $56,250
Therefore, the value of the car after owning it for 3 years is $7,910.15. This is the option (C) in the given choices.

The explanation on why △ACF is 30°-60°-90° triangle is given below.
How to explain the informationWith a regular hexagon, each of its sides and angles are equal in measure. Consider the centre of the encompassing circle, connected to two neighbouring vertices - labeled A and B here. This then creates a radius wherein the length of AB is basically equal to any other side, denoted as 's'. Furthermore, △ABF will be an isosceles triangle (with AB = BF).
From these facts, we can produce △ACF which is a right angled triangle – with AC being its hypotenuse, A F and FB both equating to s/2, finally concluding that ∠AFB is equivalent to 120°/2 = 60° while establishing that ∠ACF is also a right angle constituent making △ACF essentially a 30°-60°-90° triangle.

Answers
C. Yes; the graph passes the vertical line test.
How does the graph below represent a function?The correct answer is C. Yes; the graph passes the vertical line test.
To determine whether a graph represents a function, we apply the vertical line test. The vertical line test states that for a graph to represent a function, no vertical line should intersect the graph in more than one point.
In this case, the graph passes the vertical line test if each vertical line crosses the graph at most once. If this condition is satisfied, then each x-value corresponds to a unique y-value, indicating that the graph represents a function.
Since the question states that the graph passes the vertical line test, we can conclude that it represents a function.

The perimeter of Koch's snowflake fractal will be infinite.
Find out how Koch's snowflake fractal is created by adding triangular bumps to the side of an equilateral triangle?Koch's snowflake fractal is created by adding triangular bumps to the sides of an equilateral triangle at progressively smaller scales. At each stage, the number of sides of the resulting figure increases by a factor of 4, and the perimeter of the figure increases as well.
To see how the perimeter changes as bumps are added to all sides of the figure, we can use the fact that each bump adds a segment of length 1/3 to the original side. So if we start with a triangle of side length 1 and add a bump to each side, the new perimeter is:
P = 3(1 + 1/3) = 4
Now we have a figure with 12 sides. If we add a bump to each of these sides, the new perimeter is:
P = 12(1 + 1/3 + 1/9) = 16/3
In the next stage, we have 48 sides, and each side has a length of 1/3^2, so the new perimeter is:
P = 48(1 + 1/3 + 1/9 + 1/27) = 64/3
At each stage, we can see that the perimeter is multiplied by a factor of 4/3. So if we carry on this process forever, the perimeter of Koch's snowflake fractal will be infinite.

A speaker is in the shape of a cube with an edge length of 3. 5 inches. The speaker is sold in a package in the shape of a square prism with a base area of 16 square inches and a height of 4. 25 inches. How much empty space, in cubic inches, remains in the package after the speaker is placed in the package?
Answers
The volume of the cube-shaped speaker is 42.875 cubic inches. The volume of the package is 68 cubic inches. Subtracting the volume of the speaker from the volume of the package gives the empty space remaining, which is 25.125 cubic inches.
The volume of the cube-shaped speaker is given by V₁ = (edge length)³ = 3.5³ = 42.875 cubic inches.
The volume of the square prism-shaped package is given by V₂ = (base area) x (height) = 16 x 4.25 = 68 cubic inches.
Therefore, the empty space remaining in the package after the speaker is placed in it is V₂ - V₁ = 68 - 42.875 = 25.125 cubic inches.
So, the empty space remaining in the package is 25.125 cubic inches.

each day. How many times a day would we have to fill the container
shown below?
80 times
40 times
16 times
4 times
HELPPPPP PLEASEEEEEE!!!!!!!
Answers
To determine how many times a day we would need to fill the container shown below, we need to calculate its capacity in cubic centimeters. Let's assume that the container is a rectangular prism with dimensions of 30 centimeters (length) x 20 centimeters (width) x 25 centimeters (height). The formula for calculating the volume of a rectangular prism is:
Volume = length x width x height
Plugging in the values we have, we get:
Volume = 30 cm x 20 cm x 25 cm
Volume = 15,000 cubic centimeters
Therefore, the container has a capacity of 15,000 cubic centimeters. To determine how many times we would need to fill it each day, we need to divide the amount of pellets and hay we feed the okapi daily (5,024 cubic centimeters) by the capacity of the container (15,000 cubic centimeters):
5,024 / 15,000 = 0.3356
This means that we would need to fill the container approximately 0.3356 times a day, which is not a practical answer. We need to round this up to the nearest whole number.
The options given to us are 80 times, 40 times, 16 times, and 4 times. Out of these options, the closest whole number to 0.3356 is 1, which means we would need to fill the container once a day.
Therefore, the answer is that we would need to fill the container shown below 1 time a day to feed the okapi their daily amount of pellets and hay.

Given that abcd is a rhombus, determine the length of each diagonal, ac, and bd if m∠ade=20° and ad = 8cm. please help and show me how you did it
Answers
The length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm
Rhombus is a special type of parallelogram in which all four sides are congruent. The opposite angles of a rhombus are also congruent, and the diagonals bisect each other at right angles.
Now, let's consider the given rhombus abcd, where ad = 8cm and m∠ade=20°. We need to determine the length of diagonals ac and bd.
First, let's use the law of cosines to find the length of side ae. We know that ad = 8cm, and m∠ade=20°, so we can use the formula:
ae² = ad² + de² - 2ad(de)cos(m∠ade)
Substituting the values, we get:
ae² = 8² + de² - 2(8)(de)cos(20°)
Next, we can use the fact that a rhombus has all sides congruent to find the length of side de. Since abcd is a rhombus, we know that ac and bd are also congruent diagonals that bisect each other at right angles. Therefore, we can draw diagonal ac and use the Pythagorean theorem to find the length of ac:
ac² = (ae/2)² + (de/2)²
Substituting ae² from the previous equation, we get:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Simplifying the equation and using the fact that ac and bd are congruent, we get:
bd² = ac² = (8² + de² - 2(8)(de)cos(20°))/2
Finally, we can use the Pythagorean theorem to find the length of diagonal bd:
bd² = ab² + ad²
Substituting ab = ac/2 and ad = 8cm, we get:
bd² = (ac/2)² + 8²
Substituting ac² from the previous equation, we get:
bd² = ((8² + de² - 2(8)(de)cos(20°))/8)² + 8²
Simplifying the equation, we get:
bd ≈ 12.22 cm
Similarly, we can solve for ac using the equation we derived earlier:
ac² = ((8² + de² - 2(8)(de)cos(20°))/4) + (de/2)²
Substituting de ≈ 9.84cm (which we can solve for from the equation ae² = 8² + de² - 2ad(de)cos(m∠ade)), we get:
ac ≈ 15.58 cm
Therefore, the length of diagonal ac is approximately 15.58 cm, and the length of diagonal bd is approximately 12.22 cm
