Which equation represents the area,y, of the trapezoid​

Mathematics
1 answer:
erik [133]3 years ago
4 0

Answer:

C.  y =  x^2 + 4x.

Step-by-step explanation:

Area of a trapezoid = (h/2)(a + b)   where h is the altitude and a and b are the lengths of the parallel sides.

So here

Area y  = (x/2)(8 + 2x)

= 8x/2 + 2x^2/2

= 4x + x^2.

GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using the distance formula, we get the distance between first ride and second ride in the map is

d=\sqrt{(3-0)^2+(0-4)^2}

d=\sqrt{9+16}

d=\sqrt{25}

d=5

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units  = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.

Gre4nikov [31]

Answer:

254,251,200

Step-by-step explanation:

This is a combination question, since the order doesn't matter, the formula for combinations is n!/(n-r)! n is the amount of things we can choose from but r is the amount of things (employees in this case) we actually select. n = 50 and r = 5. This we get 50!/(50-5)! or 50!/45!, using a calculator, we can find that 50!/45! is equal to 254,251,200. That is our final answer for the amount of combinations available.

nirvana33 [79]

Answer:

y=15x+126

Step-by-step explanation:

the slope is

15 because -8-(-9) is 1 and 6-(-9) is 15 and y is over x so slope 15

To find y intercept start from -8,6 and add 15 to the y value every time you add one to the x value

you will add 8 times and you get 126 as the intercept
