Answer:
D) a = b= 2√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...
a√2 = 4
a = 4/√2 = 4(√2)/2 = 2√2
Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...
a = 2√2, b = 2√2
<h3>
Answer:</h3>
<u>It squares the amount you scaled it by.</u>
<h3>
Step-by-step explanation:</h3>
For example, imagine that you had 2 by 2 square, and then you put it through a scale factor of 2.
Now each side length would be double of what it once was.
But when you multiply the new lengths together, the area would be of 4 times more.
(Original Equation) 2 * 2 = 4
(Scale Factor of 2) 4 * 4 = 16
So when the scale factor is made, the area would be squared to the multiple that you scaled it by.
<em>***A square root is a number times itself.</em>
<em>(eg): 3 * 3 = </em><em>9</em>
<em> 15 * 15 = </em><em>225</em>
<em>9 and 225 would be the square root in these problems.</em>

Find Radius :
--------------------------------------------------------
Base area = πr²
169π = πr²
r² = 169
r = √169
r = 13 cm
--------------------------------------------------------
Find height :
--------------------------------------------------------
Height = 13 + 4
Height = 17 cm
--------------------------------------------------------
Find Volume :
--------------------------------------------------------
Volume = πr²h
Volume = π(13)²(17)
Volume = 9025.8 cm³
--------------------------------------------------------
Answer: Volume = 9025.8 cm³

Answer:
15 m^2
Step-by-step explanation:
Find the area of the bottom square
A = s^2 = 3^2 = 9 m^2
Then find the area of the top rectangle
A = l*2 = 3*2 = 6 m ^2
Then add the areas together
9+6 = 15 m^2
Answer: Slope: 3
Step-by-step explanation:
Slope formula: m=(y2-y1)/(x2-x1)
m=(4-(-2))/(3-1)
m=(4+2)/2
m=6/2
m=3
