megan is trying to find the length of the segment using the Pythagorean Theorem
Part A : megan made one mistake in her work , which caused her to get the wrong answer what did she do wrong?
Part B : Calculate the correct length of the segment
Answer:
10
Step-by-step explanation:
To obtain the length of the segment :
a² + b² = c²
a = 8 ; b = 6
8² + 6² = c²
64 + 36 = c²
100 = c²
Square root of both sides :
Sqrt(100) = sqrt(c²)
10 = c
Mistake in the solution is that 6² = 36 and not 12

Answer:
$26.25
Step-by-step explanation:
We are told that Marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost $15.75.
First of all we will find cost of 1 bag of cat food by dividing 15.75 by 3.
Now we will find the amount that Marco has spend for 5 bags of cat food by multiplying 5.25 by 5.
Therefore, Marco has spend $26.25 for purchasing 5 bags of cat food.
Answer:
5.25 per bag
Step-by-step explanation:
Just divide the amount of money by the number of bags needed.
15.75 divided by 3 = 5.25

Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

The graph of a quadratic function in shown below.
Which statements about this graph are not true? Select all that apply.
A.
The graph has a y-intercept at (0,5).
B.
The graph has a relative maximum point (-3,4).
C.
The graph has an x-interceptat (1,0).
D.
The graph has the y-axis as a line of symmetry.
E.
The graph has zeros at x = -5 and x = -1.
F.
The graph represents the function f(x) = -x2 - 6x - 5.
Answer:
E
Step-by-step explanation:
The statements that are not true are:
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.
Options, A, B, and E are the correct answer.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
- The y-intercept can be found by setting x=0, which gives f(0)=-5.
So the y-intercept is (0,-5).
- To find the relative maximum,
We need to find the vertex of the parabola.
The x-coordinate of the vertex is given by -b/2a, where a=-1 and b=-6.
So, x=3 is the x-coordinate of the vertex.
To find the y-coordinate, we plug in x=3 into the function:
f(3) = -(3²) - 6 (3) - 5 = -32.
So the vertex is (3,-32), which is a relative minimum, not a maximum.
- To find the x-intercepts,
We set y =0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
- The y-axis is a line of symmetry for any parabola of form f(x)=ax²,
f(-x) = a (-x)² = ax² = f(x).
- To find the zeros,
We set f(x) = 0 and solve for x.
-x² - 6x - 5 = 0.
Factoring or using the quadratic formula,
We get x = -5 and x = -1.
So the graph has zeros at x = -5 and x = -1, not x = -2 and x = 3.
- The graph represents the function f(x) = -x2 - 6x - 5.
The graph is true.
Thus,
The graph has a y-intercept at (0,5) is not true.
The graph has a relative maximum point (-3,4) is not true,
The graph has zeros at x = -5 and x = -1 is not true.

Answer:
240
Step-by-step explanation:
that is it
The surface area of one box is 62 square inches.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, Yolanda makes wooden boxes for a crafts fair.
The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.
We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)
Now, surface area = 2(5×3+3×2+2×5)
= 2(15+6+10)
= 2(31
= 62 square inches.
Therefore, the surface area of one box is 62 square inches.

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function C(f) = 24f represents the number of cookies, C, that can be made with f cups of flour. Which set of ordered pairs represent points on the graph of C(f) = 24f?
Answer:
c(0) = 24*0 = 0
c(8) = 24*8 = 192
Your range is [0,192]
Step-by-step explanation:
Answer:
You have 8 cups of flour it takes 1 cup of flour to make 24 cookies the function c(f)=24f
c represents the number of cookies
f represents the cups of flour
You have 8 cups of flour, we can use only 0 to 8 cups of flour.
so domain f is 0 to 8 cups [0,8]
Now we find the range
1 cup of flour to make 24 cookies
So 8 cups of flour = 24* 8 = 192 cookies
using 8 cups you can make 192 cookies
So number of cookies is from 0 to 192
Range is [0,192

Gilbert is -17 meters under sea level every second(s) he gains 0.5 meters after how many seconds is he at sea level?
Answer:
He is at sea level after 34 seconds
Step-by-step explanation:
The height at sea level is given as 0 meters
So the change in height would be;
0- (-17) = 17 meters
There is a gain of 0.5 meters in 1 second
So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds
