A.
75 inches
B.
39 inches
C.
36 inches
D.
72 inches
Answer:
B. 39 inches
Step-by-step explanation:
The amplitude is the difference between the function's maximum and minimum values.

Which measurements is equivalent to 4,000 centimeters? (100 centimeters = 1 meter)
Answer:
400 meters = 4000 centimeters
Step-by-step explanation:
Sorry if this didn't help
The solution is , 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.
What is equation?An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.
Here,
we know,
100 centimeters = 1 meter
Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.
So, to convert 40 meters to centimeters, we can multiply 40 by 100:
40 meters = 40 x 100
= 4,000 centimeters
Therefore, 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

Help i will give brainlist. The quotient of 2 and g is 8 can u pls show me step by step ty
Answer:
16
Step-by-step explanation:
Set up the equation: g/2 = 8
We want to get 'g' by itself, so we need to reverse the division of two. To do that, we multiply (division and multiplication go together, addition and subtraction go together) both sides by two (what you do to one side of an equation, you must do to the other).
End up with: g = 16
Hope this helps :)

mary need 50 ft of fence to protect her rectangular garden from squirrels. How long and how wide is the 8 ft more than the width length is if the length is 8 ft more than the width
Answer:
Width of the fence = 8.5 ft
Length of the fence = 16.5 ft
Step-by-step explanation:
Mary need 50 feet of fence to protect her rectangular garden from squirrels. How long and wide is the garden if the length is 8 feet more than the width?
Perimeter of the fence = 2(length + width)
Perimeter of the fence = 50 ft
Width of the fence = x ft
Length of the fence = x + 8 ft
Perimeter of the fence = 2(length + width)
50 = 2{(x+8) + (x)}
50 = 2(x + 8 + x)
50 = 2(2x + 8)
50 = 4x + 16
50 - 16 = 4x
34 = 4x
x = 34/4
x = 8.5
Width of the fence = x ft
= 8.5 ft
Length of the fence = x + 8 ft
= 8.5 + 8
= 16.5 ft
Width of a rectangle is equal to [tex]\boldsymbol{8.5}[/tex] feet and length is equal to [tex]8.5+8=\boldsymbol{16.5}[/tex] feet
Perimeter of a rectangleA quadrilateral having four right angles is known as a rectangle. It can also be described as a square - shaped quadrilateral (equiangular meaning all angles are identical) or a parallelogram with a right angle.
Let [tex]x[/tex] denotes the width [tex](w)[/tex] of a rectangle.
So,
Length of a rectangle [tex](l)=x+8[/tex]
Perimeter of a rectangle [tex]=50[/tex] feet
[tex]2(l+w)=50\\l+w=25\\x+8+x=25\\2x=17[/tex]
[tex]x=8.5[/tex] feet
So,
width is equal to [tex]\boldsymbol{8.5}[/tex] feet and length is equal to [tex]8.5+8=\boldsymbol{16.5}[/tex] feet

PQ = 26
Answer:
x = 31.4
PQ = 58.8
Step-by-step explanation:
Set up a proportion:
SQ/QP = ST/PR
Substitute in the values they give you:
[tex]\frac{x-9}{x-9+x+5} = \frac{8}{21}[/tex]
[tex]\frac{x - 9}{2x - 4} = \frac{8}{21}[/tex]
[tex]21x - 189 = 16x - 32\\5x = 157\\x = 31.4[/tex]
This means that PQ = 2x - 4 = 2(31.4) - 4 = 62.8-4 = 58.8
Answer:
x = 15, PQ = 26
Step-by-step explanation:
x+13/9 = 21/x-9
x^2+4x−117=168
x^2+4x−285=0
(x−15)(x+19)=0
x=15
it cannot be a negative number so x cannot be -19
PQ= x+13

f(x)= 3x and g(x)= -x+4, so f(g(2))=?
Answer: 6
Step-by-step explanation: first, you plug in 2 into the g(x) function. So, replace x with 2 in the second function g(x). -2 + 4 = 2. Then take that answer (2), and plug that into the x for f(x). 3 x 2 = 6
Answer:
[tex]f(g(2))=6.[/tex]
Step-by-step explanation:
We have [tex]g(x)=-x+4 \Rightarrow g(2)=-2+4=2[/tex]
Since [tex]f(x)=3x[/tex] then [tex]f(g(2))=f(2)=3.2=6.[/tex]
A swimming pool measures 10 feet by 8.5 feet by 5 feet. How many cubic feet of water will the swimming pool hold?
Answer:
425 Cubic Feet
Step-by-step explanation:
Cubic feet is volume meaning that in order to find the volume you must multiply the length, width and the height. The answer is 425
The swimming pool will hold 425 cubic feet of water.
What is the volume of a rectangular prism?The volume of the rectangular prism is defined as the space in three-dimension covered by the rectangular prism having the sides Length, Width, and Height.
To find the volume of the swimming pool in cubic feet, we need to multiply the length, width, and height of the pool:
The volume is calculated as,
Volume = length x width x height
Volume = 10 ft x 8.5 ft x 5 ft
Volume = 425 cubic feet
Therefore, the swimming pool will hold 425 cubic feet of water.

segment YZ is length a, we need to find a
segment XZ is length 5
segment XY is length 12
XYZ is a right triangle, so a^2 + b^2 = z^2, so

A swim team ordered 36 jackets that each cost the same amount. The total cost of the order was $1,116. Let c be the cost of each jacket. How much did each jacket cost?
Answer:
c = $1116/36
c = $31
Step-by-step explanation:
the cost of each jacket can be determined by dividing the total cost of the 36 jackets by the number of jackets bought
cost of each jacket = total order cost / total number of jackets bought
$1116 / 36 = $31
Each jacket costs $31
