Competency: Write the linear equations Ax + By = C. Give the value of A,B, and C,.
Answer:
see explanation
Step-by-step explanation:
(1)
y = - x + 4 ( add x to both sides )
x + y = 4
with A = 1, B = 1, C = 4
(2)
y = 5x + 7 ( subtract y from both sides )
0 = 5x - y + 7 ( subtract 7 from both sides )
- 7 = 5x - y , that is
5x - y = - 7
with A = 5, B = - 1, C = - 7
----------------------------------------------------------
(1)
2x + y = 9 ( subtract 2x from both sides )
y = - 2x + 9
with m = - 2, c = 9
(2)
5x + 2y = 7 ( subtract 5x from both sides )
2y = - 5x + 7 ( divide terms by 2 )
y = - [tex]\frac{5}{2}[/tex] x + [tex]\frac{7}{2}[/tex]
with m = - [tex]\frac{5}{2}[/tex] , c = [tex]\frac{7}{2}[/tex]

I don't understand the problem. Can you help me solve it please? I also have an IEP.
Answer:
12
Step-by-step explanation:
The Pythagorean theorem is
a^2+b^2 = c^2 where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)
a^2 + b^2 = c^2
Substitute the known values
5^2 + b^2 = 13^2
25+b^2 = 169
Subtract 25 from each side
25+b^2-25 =169-25
b^2 = 144
Take the square root of each side
sqrt(b^2) = sqrt(144)
b=12
Answer:
Given:
a = 5c = 13To find:
missing side b
Solution:
Using Pythagorean theorem,
(Hypotenuse² = base² + perpendicular²)
b² = c² - a²
= 13² - 5²
= 169 - 25
= 144
b = √144
= 12

1. Find the volume.
8 5 and 1
Answer:
40
Step-by-step explanation:
The figure shown is a rectangular prism with a length of 1, a width of 8 and a height of 5 and given this information we want to find the volume
The volume of a rectangular prism can easily be calculated by multiplying the width by the length by the height
so the volume of this rectangular prism specifically = 5 * 8 * 1
5 * 8 = 40
40 * 1 = 40
so the volume is 40

What is 20% of 90???
Answer: 18
Step-by-step explanation:
First we want to turn 20% into a decimal so we can multiply it by 90.
So to do that we divide 20 by 100.
20/100=0.2 so 0.2 is the decimal form of 20%.
Then we multiply 90 by 0.2 to get 18 as our answer.
Answer:
Answer: 20% of 90 is 18.
Let's find 20% of 90.
Explanation
20% of 90 can be written as 20% × 90
= 20/100 × 90
= 18
Thus, 20% of 90 is 18.

Answer: B) Yes, the graph passes the vertical line test.
========================================================
Explanation:
Ask yourself if it is possible to draw a single straight vertical line through more than one point on the red parabola. Since such as task is not possible in this case, we consider this curve to be "passing the vertical line test". It means that any x value input leads to exactly one and only one y value output.
The top edge of the window is a semicircle. The distance across the window is 2.5 ft. What is the distance around the top edge of the window? Use 3.14 for π, and round your answer to the nearest tenth.
2.5 ft
3.9 ft
5 ft
7.85 ft
Answer: 3.9 ft
Step-by-step explanation:
From the question, the distance across the window which is 2.5 ft is the diameter. Therefore, radius will be:
= 2.5 / 2
= 1.25 ft
Then, we calculate the circumference of the circle which will be:
= 2πr
= 2 × 3.14 × 1.25
= 7.85 ft
Nite that it's a semi circle, therefore we divide the perimeter by 2. This will be:
= 7.85/2
= 3.9 feet

1. You start a biology experiment with 4,500 cells. The cells are continuously growing and 2 minutes later
there are about 22583 cells. What is the rate of growth per minute?
Answer:
80.65% per minute
Step-by-step explanation:
For continous growth :
A = Pe^rt
A = amount after time, t
P = initial amount
r = growth rate
22583 = 4500 * e^r*2
22583 = 4500 * e^2r
22583 / 4500 = e^2r
5.0184444 = e^2r
Take the In of both sides
1.61312 = 2r
r = 1.61312 ÷ 2
r = 0.80656
0.80656 * 100% = 80.65%

B.
0.3%
C.
2.5%
D.
5%
Answer: the true answer is A
Step-by-step explanation:
Good luck, give Brainliest
Using the normal distribution, it is found that the probability that more than 524 customers will come to the store on a given day is given by:
A. 0.15%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In this problem, the mean and the standard deviation are given, respectively, by:
[tex]\mu = 428, \sigma = 32[/tex].
The probability that more than 524 customers will come to the store on a given day is one subtracted by the p-value of Z when X = 524, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{524 - 428}{32}[/tex]
Z = 3
Z = 3 has a p-value of 0.9985.
1 - 0.9985 = 0.0015 = 0.15%.
Hence option A is correct.

Two months ago, the price, in dollars, of a cell phone was c.
a Last month, the price of the phone increased by 10%. Write an expression for the price of the phone
last month.
b. If the price of the cell phone was originally $399. how much is was it last month?
(From Unit 4, Lesson 8)
Answer:
Step-by-step explanation:1.1c
The expression for the price last month is 1.1c, and the cell phone was $438.9 last month
The expression for the price last month?The given parameters are:
Initial price = cIncrement = 10%The price last month would be:
Price = Initial price * (1 + Increment)
This gives
Price = c * (1 + 10%)
Evaluate
Price = 1.1c
The actual price last monthWe have:
c = 399
So, the expression becomes
Price = 1.1 * 399
Evaluate
Price = 438.9
Hence, the cell phone was $438.9 last month

The Sea Dragon, a pendulum ride at an amusement park, moves from its central position at rest according to the trigonometric function P(t)=−10sin(pi/3t), where t represents time, in seconds. How many seconds does it take the pendulum to complete one full cycle?
A= 3
B= 5

The time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)
What is the period of sine function?Trigonometric functions are periodic. They repeat their values after some specific constant input interval (constant depends on the trigonometric function chosen).
For sine function, its period is 2π
Thus, we get:
[tex]y = \sin(x) = \sin(x+2\pi) = \sin(x + 2\pi n) ; n \in \mathbb Z[/tex] integer, and y is some constant at some constant value of x)
For this case, the pendulum's motion is modeled by:
[tex]P(t) = -10\sin\left(\dfrac{\pi}{3} t\right)[/tex]
Let it takes 'd' seconds to do one full cycle, then we get:
[tex]P(t) = P(t+d) = P(t+2d) = P(t + nd); n \in \mathbb Z - \mathbb Z^{-}[/tex] (n is non-negative integer).
Using the formula, we get:
[tex]-10\sin\left(\dfrac{\pi}{3} t\right) = -10\sin\left(\dfrac{\pi}{3} (t + nd)\right)\\\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t + \dfrac{\pi}{3}nd\right)[/tex]
But we know that:
[tex]\sin\left(\dfrac{\pi}{3} t\right) =\sin\left(\dfrac{\pi}{3}t +2\pi n\right)[/tex]
Thus, we get:
[tex]2\pi n = \dfrac{\pi}{3}nd\\[/tex] (compared for non-negative values of n)
This gives:
[tex]d = \dfrac{2\pi n \times 3}{\pi n} = 6[/tex] (in seconds)
Thus, the time (in seconds) that it take the pendulum to complete one full cycle is given by: Option C: 6 (seconds)
