A ladder is 6 m long.

IRISSAK [1]

Answer:

5.8 m

Step-by-step explanation:

Using the Pythagorean Theorem (a² + b² = c²) you get the equation a² + 1.5² = 6² (or 1.5² + b² = 6²). Then you solve from there and rounding to the first decimal place you get 5.8

Write a function rule for the volume of the cylinder shown at the right with a height 3 in more than 4 times the radius of the c

Ludmilka [50]

we know that

The volume of a cylinder is equal to

$V=\pi r^{2} h$

where

r is the radius of the base

h is the height of the cylinder

In this problem

$h=3+4r$

For $r=2\ in$

Find the value of h

$h=3+4*2$

$h=11\ in$

Find the volume of the cylinder

$V=\pi*2^{2}*11$

$V=44*\pi\ in^{3}= 138.2\ in^{3}$

therefore

the answer is

The volume of a cylinder is equal to $138.2\ in^{3}$

Write an algebraic rule to describe the translation C(5,-4) — C'(-2, 1).

SpyIntel [72]

Option C. (x,y) → (x-7,y+5) is the correct answer

Further explanation:

Given

C(5,-4) — C'(-2, 1)

We will apply each translation rule one by one to check the correct algebraic rule.

A. (x,y) → (x - 2,y+1)

C(5, -4) → (5-2, -4+1) → C'(3,-3)

B. (x,y) → (x+7,y-5)

C(5, -4) → (5+7, -4-5) → C'(12,-9)

C. (x,y) → (x-7,y+5)

C(5, -4) → (5-7, -4+5) → C'(-2,1)

Hence, option C. (x,y) → (x-7,y+5) is the correct answer
