Step-by-step explanation:
The circumference of this tabletop is 24π inches, Which of the following best describes how to determine the area of the tabletop?
A) Multiply 2(24) to calculate the diameter. Then multiply the diameter by π
B Find half of 24 to calculate the radius. Then multiply the radius by π.
C Multiply 2(24) to calculate the diameter. Then square the diameter and multiply the result by it π
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Answer:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
Step-by-step explanation:
Given that circumference of circle is: [tex]24 \pi[/tex]
The formula for circumference of circle is:
[tex]C = 2\pi r[/tex]
Comparing both formulas, we get
[tex]24\pi = 2\pi r\\24 = 2r\\r = \frac{24}{2}\\r = 12[/tex]
The radius is obtained by dividing 24 by 2.
We also know that the area of circle is:
[tex]A = \pi r^2[/tex]
The radius is being squared and then multiplied by pi to get the area.
Hence,
The correct answer is:
D Find half of 24 to calculate the radius. Then square the radius and multiply the result by π.
1. Which of the following relations are functions?
Give reasons.
(a) R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
(b) R2 = {(1, 2) (1, 3) (1, 4) (1,5)}
(c) R3 = {(x, y) (y, z) (z, t) (t, v)}
Answer:
R1 = {(1, 7) (2, 7) (4, 7) (6, 7)}
R3 = {(x, y) (y, z) (z, t) (t, v)}
R1 and R3 are functions because first element in the ordered pair is not repeating, i.e they have unique images

where do the numbers go and explain how you decided where to place the numbers
Answer:
Between 0 and 1 goes 1/4 then after that is 5/8 then between the 1 and the 2 put 1 and 3/8/
Step-by-step explanation:
The reason for this is simply smallest to biggest. Which is bigger 1/4 or 5/8? Well if you want you can put it into a decimal: 1/4 = 0.25 and 5/8 equals 0.625. So 0.25 is closer to 1 and then 5/8 is the next closest to 1 but it is closer to 2. And lastly 1 and 3/8 is more then 0 and it's more then 1 so it goes in between 1 and 2 This is how it goes: 0 1/4 5/8 1 1 and 3/8 2

Cassie wants to mount an 18 cm x 18 cm square picture on a square board that is four times the area of the picture.
What is the area of the picture?
What is the area of the board?
What are the dimensions of the board?
9514 1404 393
Answer:
picture: 324 square cmboard: 1296 square cmboard dimensions: 36 cm squareStep-by-step explanation:
a) The area of the picture is the product of its dimensions:
(18 cm)² = 324 cm²
__
b) The area of the board is 4 times that:
board area = 4×324 cm² = 1296 cm²
__
c) The dimensions of the square board are the square root of its area:
√1296 = √(4×324) = (√4)(√324) = 2×18 = 36 . . . . cm
The board is 36 cm square.

What is the surface area of the square pyramid represented by the net below?
A: 48 cm
B: 96 cm
C: 64 cm
D: 112 cm
Answer: C: 64 cm
Step-by-step explanation:
The square has a a side of 4 centimeter meaning the area would be 16 cm. The area of the triangle is determined by half of the area of the base times the height. This mean that 4 x 6 = 24 and then 24/2 = 12. 4 x 12 = 48 (due to four triangles). 48 + 16 = 64. It is C: 64 cm

express x^2 -8x+5 in the form (x-a)^2 -b where a and b are integers
Answer:
(x - 4)² - 11
Step-by-step explanation:
Given
x² - 8x + 5
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
= x² + 2(- 4)x + 16 - 16 + 5
= (x - 4)² - 11

The value of a computer decreases with its age, until it is worth nothing. A computer that was purchased new (age 0 years) for
$2200 is worth $1540 after 6 years.
The linear function V(x) that expresses the value of the computer as a function of the age (x) in years is V(x)= type your answer_
The value of the computer after 8 years is $ type your answer...
After type your answer.
years the computer will be worth nothing.
Answer:
v(x)=2200-N*110
the value of computer after 8 years is 1320
Step-by-step explanation:
at 0 years the value is 2200
after 6 years the value is 1540
we should calculate how much the value of the computer decreases in one year , so we can do an interpolation to determine the value of the computer after 1 year and it is 2090$ . so, 2200-2090=110$ that means in one year the value of computer decreases 110$ so the function is v(x)=2200-n*110
where n is number of years
so after 8 years : v(8)=2200-8*110=1320$
