Hey there!

In order to solve this problem, we can use the Pythagorean Theorem, which is c^2 = a^2 + b^2. Since the Pythagorean Theorem would find only half of the length of x, we'll need to double it in the end.

First, let's plug in what we know to the Pythagorean Theorem: 2.1^2 = 1.4^2 + b^2

Next, we'll simplify to that b^2 is by itself:

b^2 = 2.45

Then, we'll find the square root of 2.45, multiply that by 2 and round to the nearest tenth:

2(\sqrt{2.45} ) = 3.1

Therefore, x = 3.1 ft.


How to round to the nearest tenth:

In a decimal, the tenth is the first number after the decimal point. To round to the tenth, if the number in the hundredth place is less than 5, you keep the number as it is, but if the number in the hundredth place is more than 5, you increase the number in the tenth place by 1.


Hope this helps!! :)

Y results from something being multiplied by x , and the values are always proportional to one another. Notice that putting these points into a ratio of x-value to y-value results in 1:3 as a simplified version. So, the constant of proportionality is what x is being multiplied by to get y . In this case, it is 3 . PLEASE MARK A THE BRAIN THINGY

Write an equation for the line that is parallel to the given line and that passes through the given point. y = –6x + 2; (–1, 2)
kap26 [50]
Parallel=same slope
Y=mx+b
Sub in the slope and point to solve for b
2=-6(-1)+b
2=6+b
2-6=b
-4=b
The equation is y=-6x-4; the answer is B
Hope this helps!
