A graphing calculator shows it takes 3.25 seconds for the shoe to hit the building.

_____
200 -16t^2 = 31
169 = 16t^2
√(169/16) = t
t = 13/4 = 3 1/4

Hello, I would really like some help on this!! Please leave an explanation of how you got your answer! Thank You!

1a) To find the total area, you must find the area of the triangular part that is missing, then subtract this from the area of the rectangle. For the triangle’s area, you need to know the width (2m) and length (2m). For the rectangle’s area you need to know the width (3m) and length (4m).
1b) the total area is 10m^2 (10 meters squared). This is found by subtracting the triangle (.5x2x2=2) from the rectangle (3x4=12).

<h3>Answer:</h3>

A. y = (-6/5)x +10

<h3>Step-by-step explanation:</h3>

The given line has a negative slope (downward to the right). The only equation offered with a negative slope is the one of selection A.

_____

<em>Complete working</em>

A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...

... slope = (change in y)/(change in x)

The coordinates of two points are given, so we can find the slope as ...

... slope = (-4-2)/(-1-(-6)) = -6/5

There are a number of ways to write the equation of a line, but in slope-intercept form, the slope is the coefficient of x. You will be looking for a choice that has an x-coefficient of -6/5.

Find the circumference of a circle with a radius of 35 inches in terms of pie add to the nearest 10th of an inch
ser-zykov [4K]

Circumference of circle = 2 π r

  • π = 3.14
  • r = 35 inches

Now , Substuting the values

Circumference of circle = 2 × 3.14 × 35

Circumference of circle = 6.28 × 35

Circumference of circle = 219.8 inches

Nearest 10ᵗʰ of 219.8 is <u>220</u>

Hence , the Circumference of circle is 220 Inches.
