Answer:

No.

Step-by-step explanation:

A scale copy would see that both the x and y amount would be scaled proportionally. In this case, the x goes across 5 for figure A, and does the same for Figure B. On the other hand, the scaling for y is 2 for figure A, while it is 5 for figure B.

If it is a scale copy then.

If Figure A have the scaling of: 3, 5, 5, x, then Figure B, if given one scale of 5, should have

3:5

5:8.33

x:(x * ~1.67)

Therefore, the scaling is off.

Step-by-step explanation:

No, it isn't

because the ratio of their lengths aren't proportional.

I believe it's the same as adding 8+3, but you add the negative sign to your answer
so 8+3 = (-?)

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing

tester [92]

The length of pendulum is 2.485 feet

<h3><u><em>Solution:</em></u></h3>

Given that,

The formula T= 2pi sqrt(L/32) relates the time, T, in seconds for a pendulum with the length, L, in feet, to make one full swing back and forth

<u><em>Therefore, the given formula is:</em></u>

$T=2\pi \sqrt{\frac{L}{32} }$

We have to find the length of pendulum that makes one full swing in 1.75 seconds

So the modify the given equation to find "L"

$T=2\pi \sqrt{\frac{L}{32} }\\\\ \sqrt{\frac{L}{32} }=\frac{T}{2 \pi}\\\\\text{Taking square root on both sides }\\\\\frac{L}{32} = \frac{T^2}{4 \pi^2}\\\\L = \frac{T^2}{4 \pi^2} \times 32\\\\L = \frac{T^2}{\pi^2 } \times 8$
