I think the answer is $12.50.

You can get this answer by dividing 1187.50 by 95

Answer:

let the third side be x

Using pythagoras theorem we get,

(58)^2 = (42)^2 + (x)^2

3364=1764+x^2

x^2=3364-1764

x^2= 1600

x=√(1,600)

x=40

Please show your work for the equation ​
zubka84 [21]

Answer:

y = x + 1

Step-by-step explanation:

We can see the line is linear so we can write the equation using y = mx + b. The components of the equation are m = slope and b = y-intercept. We can see from the graph that the y-intercept is 1 as the graph crosses the y axis at y = 1 and if we do \frac{rise}{run} or \frac{y_{2}  - y_{1} }{x_{2}  - x_{1} }, we can plug in the y-intercept's coorinates and the point in red's coordinates to get the slope of 1. Therefore, the equation would be y = 1x + 1 or y = x + 1

The function y=−16x2+36 represents the height y (in feet) of an apple x seconds after falling from a tree. Find and interpret th
Lapatulllka [165]

Answer:

A. x-intercept=x=1.5 , y-intercept=y=36

B.the apple will hit the ground after x=1.5 seconds.

Step-by-step explanation:

A. X-intercept and Y-intercept:

X-intercept:

  • the point where the line passes through X-axis i.e. point where y=0

Y-intercept:

  • the point where the line passes through Y-axis i.e. point where x=0

Given Equation:

  • y=-16x^2+36

Finding X-intercept:

to find x-intercept, put y=0 in the given equation as

0=-16x^2+36\\

adding -16x^2 to both sides of the equation, we get

16x^2=36

dividing both sides by 16, we get

x^2=\frac{36}{16}\\x^2=2.25

taking√ on both sides of the equation, we get

x=\sqrt{2.25}\\ x=1.5

Finding Y-intercept:

to find y-intercept, put x=0 in the given equation

y=-16(0)^2+36\\y=36

thus x-intercept=x=1.5

and y-intercept=y=36

B.when will the apple hit the ground after x seconds?

In the given equation if x represent the time in seconds then y represents the height of the tree from which the apple is fallen down

so if the apple hits the ground, at this stage the height is zero so y=0, thus we get x as

0=-16x^2+36\\

dividing both sides by 16, we get

x^2=\frac{36}{16}\\x^2=2.25

taking√ on both sides of the equation, we get

x=\sqrt{2.25}\\ x=1.5

the apple will hit the ground after x=1.5 seconds.
