Answer:

13.3 feet

Step-by-step explanation:

This question can be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length = 20

b = base

c = diagonal = 24

24^2 = 20^2 + b^2

576 = 400 + b^2

b^2 = 176

b = 13.3

For a proof by induction of the math statement below, identify the correct step for proving the theorem is true for n = k + 1. H

Pavel [41]

<h3>Answer: Choice A</h3>

What we do is simply replace every n with k+1. So (3n)^2 turns into (3(k+1))^2

We see that only choice A has the correct term mentioned on the left hand side, so this must be the answer.

The right hand side is treated the same way. We plug in n = k+1. Your teacher did a bit of algebraic manipulation to get what is shown for choice A.

Write an expression in simplest form for the area of a rectangle with length 6c meters and width 2 meters.

zloy xaker [14]

Answer:

12c square meters

Step-by-step explanation:

We know that

Area of a rectangle = length (L)× width(w)

Here it is given that length ,and width of the rectangle is 6c meters and 2 meters respectively.

Therefore, required area of the rectangle = 6c × 2 = 12c square meters.

Could use the help! thanks again!

love history [14]

Answer:

Beth is incorrect.

It is a translate to the right 5 units and up 1 unit.

When we solve x-5=0 we get x=5, not x=-5 which says we go right 5 units.

When we plug in 5 into the expression for g, we get 1 which means go up 1 as well.

Step-by-step explanation:

So $g(x)=\sqrt{x-5}+1$ is actually a translated 5 units and up 1 unit. Why?

Let's take there point (0,0) and figure out what the new point is on the translated graph.

We need to figure out when the inside of our square root for g is 0. This is where the graph of g will start at and continue on.

x-5=0 when x=5 ( I added 5 on both sides).

So let's plug in 5 to see what the new point is.

$g(5)=\sqrt{5-5}+1$

$g(5)=\sqrt{0}+1$

$g(5)=0+1$

$g(5)=1$

So the new graph, g, starts at the point (5,1).
