Determine if the sequence below is arithmetic or geometric and determine the common difference / ratio in simplest form. . 4,2,1,...
Answer: Geometric sequence
Step-by-step explanation:
The common ratio will be:
= 2nd term / 1st term
= 2/4
= 1/2
Also, Using thw 3rd and 2nd term gives:
= 1/2
Common difference will be:
= 2nd term - 1st term
= 2 - 4
= -2
Using thw 3rd and 2nd term gives:
= 1 - 2
= -1
From the above, we can see that it's a geometric progression as the common ratio is thesame.

The length of a rectangle in centimeters is two more than thrice its width. a) Write an expression, in the simplest form, for the perimeter of the rectangle. b) Find the length of the rectangle if the perimeter is 36 cm
Answer:
Perimeter of the rectangle = 8 x +4
Length of the rectangle = 12 units.
Step-by-step explanation:
Let the width of the rectangle as 'x' units.
So, length of the rectangle is 2 more than 3 x.
We can set up expression for length as 3 x+2.
Now, perimeter is sum of all side lengths of the rectangle.
So, perimeter = x+x+3 x+2 +3 x+2
Combine like terms,
Perimeter = 8 x+4
Now, it is given perimeter is 36cm
So,
8 x+4=36
Subtract both sides 4
8 x=32
Divide both sides by 8
x=4
So, width of the rectangle =4
Length =3(4) +2=14

The distance between point A and point D = units
Answer:
8.06 units = AD
(just write sq rt 65 = 8.062 ) then write or try sq rt of 65 to 3 sf = nearest tenth 8.06 tenth units rounded.
Step-by-step explanation:
AE = 7
ED = 4
We use Pythagoras Theorem as it is a right angle as AE^2 + ED^2 = AD^2
7^2 + 4^2 = AD^2
49 + 16 = 65 sq rt
sq rt 65 = AD^2 = 8.062^2
AD = 8.062 units
In order for a rhombus to be proven using either its sides or angels, it must first be proven to be a
Answer:
It must be proven to be a quadrilateral
Step-by-step explanation:
The question is straightforward, and it requires a direct answer.
A rhombus has four sides and as such it means it is a type of quadrilateral.
So, before a shape is proven to be a rhombus, it has to first be proven to be a quadrilateral.

5.4°
15.4°
9514 1404 393
Answer:
(c) 5.4°
Step-by-step explanation:
We can simply determine the difference between the angles of the vectors:
arctan(8/-5) -arctan(8/-4) = 122.005° -116.565° = 5.440°
The angle between the vectors is about 5.4°.
__
Alternate solutions
1) We could also determine the angle of their ratio.
u/v = (-5 +8i)/(-4 +8i) = (-5 +8i)(-4 -8i)/(4² +8²) = (84 +8i)/80 = 1.05 +0.1i
angle = arctan(0.1/1.05) = 5.440°
__
2) Tan(a-b) = (tan(a)+tan(b))/(1 -tan(a)(tan(b))
tan(∠u -∠v) = ((tan(∠u) -tan(∠v))/(1 +tan(∠u)tan(∠v))
= (-1.6 -(-2))/(1 +(-1.6)(-2)) = 0.4/4.2
∠u -∠v = arctan(2/21) = 5.440°

As a small step to save the environment, Luna came up with an idea for her sweet shop. In exchange for five eclaire boxes, that she gets, she decided to give an eclaire box for free. A group of kids from the locality ate seventy-seven eclaire boxes that week and they collected the boxes to give to Luna and get back eclaires boxes.
How many eclaires boxes do you think they can buy from Luna using the seventy-seven claire boxes?
Answer: 15
Step-by-step explanation:
From the question, we can infer from the information given that:
5 eclaires boxes = 1 free eclaires box.
Therefore, to get the number of eclaires boxes that the kids will get if they bring 77 eclaires boxes, we have to divide 77 by 5 and this will be:
= 77 / 5
= 15.4
= 15
The group of kids will receive 15 free boxes

Which best describes the behavior of the function
f(x)=2/3x-2?
A) It is a constant.
B) It is increasing.
C) It is decreasing.
D) It is both increasing and decreasing.
Answer:
Step-by-step explanation:
B) it is increasing, the slope of 2/3 tells you it's going up
Using concepts of linear functions, it is found that the correct option is given by:
B) It is increasing.
--------------------
The equation of a linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope, being the value that describes its behavior.
If m = 0, the function is constant.If m > 0, the function is increasing.If m < 0, the function is decreasing.--------------------
In this question, the equation of the line is:
[tex]f(x) = \frac{2}{3}x - 2[/tex]
The slope is [tex]m = \frac{2}{3}[/tex], which is positive, thus the function is increasing, and the correct option is B.

How long (in years) would $900 have to be invested at 11.3%, compounded continuously, to earn $500 interest? (Round your answer to the nearest whole number.)
Answer:
6.13 years
Step-by-step explanation:
The computation of the number of years is shown below:
As we know that
Amount = Principal ×e^{rate,time period}
($900 + $500) = $700 × e^{11.3%, time period}
$1,400 = $700 × e^{11.3%, time period}
ln(2) = 0.113× time period
0.693147181 ÷ 11.3 = time period
= 6.13 years

FIND THE ANGLE OF DEPRESSION. PLS HELP. I WILL MARK YOU A BRAINLEST
Answer:
62.2° (or 1.1 rad)
Step-by-step explanation:
Let’s call the three points A Allen’s house, B Bob’s house, T the traffic light and α “angle of depression”.
Since we have a right triangle BTA, let’s first find out the angle ∡BTA based on its opposite side AB = 7 km and the hyponenuse TA = 15 km.
∡BTA = arcsin(AB/TA) ≈ arcsin(0.4667) ≈ 0.4855 rad or 27.82°
Now since the text says the connecting line TA “is vertical to the road”, α is the rest of the right angle when ∡BTA subtracted.
α ≈ 90° - 27.82° = 62.18°
or α ≈ 0.5 π rad - 0.4855 rad ≈ 1.09 rad

In the basket and 12 of them are oranges what percentage of the pieces of fruit in the basket or orange show your work in the box and circle your answer.
Answer:
60%
Step-by-step explanation:
There are 20 pieces of fruit in a basket and 12 of them are oranges what percentage of the pieces of fruit in the basket are orange show your work in the box and circle your answer
Total oranges in the basket = 20
Number of oranges = 12
what percentage of the pieces of fruit in the basket are orange
= Number of oranges / Total pieces of fruits × 100
= 12/20 × 100
= 0.6 × 100
= 60%
Percentage of the pieces of fruit in the basket that are oranges = 60%
What two things make a graph proportional?
The bank contains pennies, nickels, dimes, and quarters. There are 4 more nickels than pennies. How much money does the bank contain
Of the 50 coins 10% are pennies and 42% are dimes
The amount of money in the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown.
First, let's find the number of pennies in the bank.
Since 10% of the coins are pennies, and there is 50 coins total, the number of pennies is :
10/100 × 50 = 5
Now let's find the number of dimes. Since 42% of the coins are dimes, and there is 50 coins total, the number of dimes is :
42/100 × 50 = 21
Since there are 4 more nickels than pennies, the number of nickels is :
5 + 4 = 9
Finally, the number of quarters is: 50 - 5 - 9 - 21 = 15
Thus, the bank contains 5 pennies, 9 nickels, 21 dimes, and 15 quarters.
