Answer:
The 1st, 4th, and 5th triangles are right triangles
Step-by-step explanation:
Right triangles always have a key characteristic. They all have an angle of 90 degrees. Keep an eye out for that.
True. F(x) is a function because “f” is the function name and “x” is the input. Or another name for y
Answer:
22350 cubic mm
Step by step:
Surface area of a cuboid is given by 2( L*B + H*L + B*H)
Thus 2(75*65 + 45*75 + 65*45) = 22350 cubic mm

Answer:
5in by 5in by 5in
Step-by-step explanation:
We are not told wat to find but we can as well find the dimension of the prism that will minimize its surface area.
Given
Volume = 125in³
Formula
V = w²h ..... 1
S = 2w²+4wh ..... 2
w is the side length of the square base
h is the height of the prism
125 = w²h
h = 125/w² ..... 3
Substitute eqn 3 into 2 as shown
S = 2w²+4wh
S = 2w²+4w(125/w²)
S = 2w²+500/w
To minimize the surface area, dS/dw = 0
dS/dw =4w-500/w²
0= 4w-500/w²
Multiply through by w²
0 = 4w³-500
-4w³ = -500
w³ = 500/4
w³ =125
w = cuberoot(125)
w = 5in
Get the height
125 =w²h
125 = 25h
h = 125/25
h = 5in
Hence the dimension of the prism is 5in by 5in by 5in
The Range of the function is {y|y is a real number} , Option D is the correct answer
<h3>What is Range ?</h3>
Range of a function is all the value a function can obtain.
From the figure it can be seen that the graph is moving slowly in either direction.
It extends from -∞ to +∞ ,
Therefore , {y|y is a real number} , Option D is the correct answer.
The complete question is
The graph shows a vertical translation of y = ³√x
What is the range of the translated function?
{y|y < 0}
{y|y ≥ 0}
{y|y is a natural number}
{y|y is a real number}
The image of the translated function is attached.
