Answer:
2.5*2.5
Step-by-step explanation:
the power of 2 means multiply that many times, so you would multiply 2.5 by itself twice, or 2.5*2.5. Simplified this is 6.25
If x=5 and y=−2, evaluate the following expression:10+5xy
Answer:
-40
Step-by-step explanation:
You can replace the values of x with 5 and the values of y with (-2).
10 + 5xy = 10 + 5 × 5 × (-2)
= 10 + 5 × (-10)
= 10 + (-50)
= -40
Answer:
-40Step-by-step explanation:
10+5xy
[By putting the value of x = 5 and y = -2 ]
= 10 + 5 × 5 × (-2)
= 10 - 50
= -40 (Ans)

Answer:
it should be 15
Step-by-step explanation:
Answer:
15 units
Step-by-step explanation:
Since the x- coordinates of both points are the same, then calculate the distance between the y- coordinates using the absolute value, that is
d = | - 8 - 7 | = | - 15 | = 15 , or
d = | 7 - (- 8) | = | 7 + 8 | = | 15 | = 15

Use the functions f(x)=10-9/2x, g(x)=|-3x+16|, and h(x)=-x^2+8
Find h(a-4). urgent please answer
The value of h(a -4) is -a² + 8a - 8
What is a function?
A function can be defined as an expression or rule that explains the relationship between a dependent and an independent variable.
Given the functions;
f(x)=10-9/2x g(x)=|-3x+16| h(x)=-x^2+8To determine h(a-4), we substitute the value of x as a - 4 in the h(x) function, we have;
h(a - 4) =- (a - 4)² + 8
expand the bracket
h(a - 4) = - ( a - 4)(a - 4) + 8
h(a - 4) = - (a²- 4a - 4a + 16) + 8
collect like terms
h(a - 4) = - a² + 8a -16 + 8
h(a - 4) = -a² + 8a - 8
Thus, the value of h(a -4) is -a² + 8a - 8

Solve for t. You must write your answer in fully simplified form.
−19=7t
Answer:
t=-19/7
Step-by-step explanation:
you need to isolate for t which means you need to get t all alone on one side of the equation. Do do that you can divide both sides by 7. This gives you -19/7=7t/7
we know that anything divided by itself is 1 so we get -19/7=t
This is the simplest for because 19 and 7 are both prime numbers, so you can't simplify them.
The equation y=250,000(1.1)x closely models the value of his home, y, when x is the number of years since 2002.
Using this equation, what would we have expected to be the value of his condo in the year 2006?
Value in 2006:
Answer:
The value in 2006 is 366,025
Step-by-step explanation:
Here, we want to get the value of y in 2006
what we have to do here is to find and substitute the missing value of x
The missing value x is the difference between the number of years in 2002 and 2006
we have this as 2006-2002 = 4
so we have to substitute 4 here for x
Thus, we have this as;
y = 250,000(1.1)^4
y = 366,025

Relationship a is defined by the equation y=9x some values of relationship b are (0,0)(3,34.5)(5,57.5)(8,92) both relationships have a direct proportion between x and y. The rate of change of relationship b is how many units greater then the rate of change of relationship a
Answer:
The rate of change of relationship 'b' is 2.5 times greater than the rate of change of relationship 'a'
Step-by-step explanation:
The given parameters are;
The function representing relationship 'a' is y = 9·x
Some values of relationship 'b' are;
(0, 0), (3, 34.5), (5, 57.5), and (8, 92)
For direct proportionality of relationship 'b' we have;
y = k₂·x
∴ k₂ = y/x
∴ k₂ = 34.5/3 = 23/2
57.5/5 = 23/2
92/8 = 23/2
k₂ = 23/2
Therefore, the direct proportionality relationship of relationship 'a' is y = 9·x
∴ k₁ = 9
Therefore, the rate of change of relationship 'b' is k₂ - k₁ = (23/2) - 9 = 2.5 times greater than the rate of change of relationship 'a'.

If Amber decides to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, the new function representing her photo shares is f(x) = 3(4)x + 45. How does this graph compare with the original graph of Amber's photo share?
Answer:
We know that Amber decided to mail copies of her photo to the 45 residents of her grandmother's assisted living facility, and after this, the function representing the photo shares is:
f(x) = 3*(4)^x + 45
We do not know the initial function, but with the given information we can assume that the original equation is:
g(x) = 3*(4)^x
Then the new function is:
f(x) = g(x) + 45.
This is a vertical translation, remember that for a function h(x), a vertical translation of N units is written as:
k(x) = h(x) + N
if N is positive, we have a translation of N units up
if N is negative, we have a translation of N units down.
in this case we have;
f(x) = g(x) + 45
This means that f(x) is a vertical translation of 45 units of g(x), then:
the graph of the new function is 45 units above the original function.

Simplify using properties of operations and then factor the expressions using the GCF. (2g + 2) - (-4g - 7)
Answer:
3(2g + 3)
Step-by-step explanation:
We start out with the expression (2g + 2) - (-4g - 7).
Firstly, let's distribute the negative:
(2g + 2) - (-4g - 7)
2g + 2 + 4g + 7
Now, combine like terms:
2g + 4g + 7 + 2
6g + 9
The GCF stands for "Greatest Common Factor." In this case, we have to find the GCF between 6 and 9. What is the GCF of 6 and 9? It would be 3. So,
6g + 9
3(2g + 3)

1. What is the mass of an object if it takes a net force of 25 N to accelerate it at a rate of 0.88 m/s2?
Answer:
28.4 kg
Step-by-step explanation:
F = ma
F is 25 N and a is 0.88 m/s^2
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
The mass of an object is 28.4 kg.
It is required to find the mass of an object.
What is force?The capacity to do work or cause physical change; energy, strength, or active power. The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body's state of rest or motion. It has a magnitude and a direction.
Given:
Net force = 25 N
Acceleration=0.88 m/s^2
According to given question we have,
F = ma
25 = 0.88m
Divide both sides by 0.88
m = 28.4 kg
Therefore, the mass of an object is 28.4 kg.

The height of the water in an above ground pool is 36 inches. The pool needs to be drained. As the water drains, the height of the water changes at a rate of -1/2 inch per minute. How many minutes will it take to drain the pool?
Answer:
72 minutes
Step-by-step explanation:
Height of water in pool = 36 inches
Drain rate = - 1/2 inch per minute
The number of minutes it'll take to fully drain :
Height of water / drain rate
= 36 / 1/2
= 36 / 0.5
= 72 minutes

Use 3.14 for π.
Enter your answer in the box to the nearest penny. will mark brainliest
Answer:
The total value of the liquid in the container is about $41,866,666.67.
Step-by-step explanation:
A spherical container has a diameter of 100 centimeters.
It is filled with a liquid that costs $80 per cubic centimeter.
And we want to determine the total value of the liquid in the container.
We can start by finding the volume of the container.
Since the container has a diameter of 100 centimeters, its radius if 50 centimeters.
The volume of a sphere is given by:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
Substitute. We will also use 3.14 for π. So:
[tex]\displaystyle =\frac{4}{3}(3.14)(50)^3=523333.33...\text{ cm}^3[/tex]
(Try not to round intermediate values.)
Since each cubic centimeter costs $80, we will multiply the total volume by the cost per cubic centimeter to find the total value. Thus, the total value is:
[tex](523333.\overline{3})(80)\approx \$41, 866, 666.67[/tex]
The total value of the liquid in the container is about $41,866,666.67.
what is the volume of the rectangular pyramid shown
Answer:
80 cm^3 = V
Step-by-step explanation:
The volume of a rectangular pyramid of base area A and height h is
V = (1/3)(base)(height).
Given that the dimensions of the base are L = 10 cm and W = 4 cm, the base area is 40 cm^2.
The height of the pyramid is h = 6 cm.
Therefore the volume of this particular pyramid is
V = (1/3)(40 cm^2)(6 cm), or V = 80 cm^3
