A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle

1 answer:

5 0

We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
$60^2+63^2 = 87^2$
$7569 = 7569$

This is, indeed correct, thus, this <em>is </em><em>a right triangle.</em>

70 POINTS! PLEASE HELP! Explain the difference between the following equation formats: Slope-Intercept, Point-Slope and Standard

katrin2010 [14]

Answer and Step-by-step explanation:

1. slope intercept

2. point-slope form

3. standard

Explanation:

1. A <u>slope intercept form</u> equation is when it's set up as y = m x + b

m = slope

b = y-intercept

2. <u>A point-slope form</u> is when a line passes through a point

and the equation is set up as y −b = m ( x−a)

m = slope

(a, b) A point that the line passes through

3. <u>standard lope form</u> is when the equation is set up as

Ax + By = C

Which function has an inverse that is a function?

fredd [130]

Answer:

m(x)

Step-by-step explanation:

they would have to pass the horizontal line test and the vertical line test for both the origional and the inverse.

b(x) does not pass the horizontal line test in any of the y values over 3

d(x) does not pass the horizontal line test for y=-9

p(x) does not pass the horizontal line test for positive y values

and m(x) has only one corresponding x value for every y value

HELP:. In baseball, the distance from the pitcher's mound to the batter is 60.5 feet. A pitcher can throw the baseball at 121 fe

zheka24 [161]

<h3>Answer: D. 5 blinks</h3>

=========================================================

Explanation:

First we'll need to find out how long it takes for the ball to go from the pitcher to the batter.

It needs to travel 60.5 feet and does so at a speed of 121 ft/sec

distance = speed*time

time = distance/speed

time = (60.5 ft)/(121 ft per sec)

time = 0.5 seconds

In half a second, the ball is from the pitcher to the batter.

------------

An eye blink is 0.1 second which means we can form this equation

0.1 second = 1 blink

We multiply both sides by 5 to get the "0.1 second" to turn into "0.5 seconds".

So,

0.1 second = 1 blink

5*(0.1 second) = 5*(1 blink)

0.5 seconds = <u>5 blinks</u> which points us to choice D.

An inverse variation function has a k value of 8. Which ordered pair is on the graph of the function?

Vinvika [58]

The points on the graph of the inverse variation are of the form:

(x, 8/x)

<h3>Which ordered pairs are on the graph of the function?</h3>

An inverse variation function is written as:

y = k/x.

Here we know that k = 8.

y = 8/x

Then the points (x, y) on the graph of the function are of the form:

(x, 8/x).

So evaluating in different values of x, we can get different points on the graph:

if x = 1, the point is (1, 8)
if x = 2, the point is (2, 4)
if x = 3, the point is (3, 8/3)
if x = 4, the point is (4, 2)

And so on.
