A triangular piece of rubber is stretched equally from all sides, without distorting its shape, such that each side of the enlar
OverLord2011 [107]

Answer:

The area of the enlarged triangle is 4 times the original area

Step-by-step explanation:

we know that

The scale factor is equal to divide the measurement of the length side of the enlarged triangle by the the measurement of the length of the corresponding side of the original triangle

In his problem

Let

x------> the length side of the original triangle

so

2x----->  is the length of the corresponding side of the enlarged triangle

scale\ factor=\frac{2x}{x}=2

scale\ factor> 1 -------> that means is increasing

The scale factor squared is equal to the ratio of the area of the enlarged triangle divided by the area of the original triangle

so

Let

m-------> the area of the enlarged triangle

n------> the area of the original triangle

r-------> scale factor

r^{2} =\frac{m}{n}

we have

r=2

substitute

2^{2} =\frac{m}{n}

m=4n

therefore

The area of the enlarged triangle is 4 times the original area

Can someone please explain how I do this. My teacher is kinda useless.

<span>when the altitude is </span>drawn from the vertex of the right angle<span> of a right triangle to its hypotenuse, the altitude equals the product</span> of the two segments of the hypotenuse<span>.
(w+9)</span>²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)

use the same method, z=√(9*11)=3√11

next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55

DaniilM [7]

Answer:

I was taught compound interest this way hopefully it helps.

100 + interest rate / 100 = multiplier

100 + 4.3 = 104.3. 104.3/100 = 1.043

Amount X multiplier to the power of time

82100 X 1.043^2 = 89312.4029

as it is a monetary unit round to 2dp

$89312.40
