Answer:

Step-by-step explanation:

A = b h

b base

h height

To find height use pythagorean theorem

5^2 = 3^2 + h^2

25 = 9 + h^2

h^2 = 25 - 9

h^2 = 16

h = 4

base = 7

height = 4

Area = 7 x 4

A = 28

First you take the area of te triangles, base x height divides by two then you just take the square area

Steve kicks a football into the air. The path that a ball takes can be described by the equation h=20t - 5t squared where h is t

FinnZ [79.3K]

Since h represents the height of the ball at any given time, t, let h = 25, such that the ball will be 25m high at t.

Now, we have 25 = 20t - 5t²
5t² - 20t + 25 = 0
t² - 4t + 5 = 0

$\frac{4 +- \sqrt{16 - 20}}{2}$

Since the discriminant is less than zero, there are no solutions.
Hence, the ball will never be 25m high.

A plumber charges $25 to come to a home, and $15 per hour for a repair. Which equation gives the total cost, y, for a repair tha

pogonyaev

Answer:

15x + 25 = y

Step-by-step explanation:

$25 is a fixed cost and will have to be paid if the plumber comes and $15 times the number of hours it takes to do the repair is the variable cost. 'x' in this case is the number of hours. So the equation will be 15x + 25 = y

Does the line whose equation is y=-2x+13 pass through the point (4,5)? Explain how you arrived at

katrin2010 [14]

Answer:

Yes

Step-by-step explanation:

Plug in 4 for x, 5 for y. if it equals, then its a point

5 = -2(4) + 13

5 = -8 + 13

5 = 5

it equals so (4,5) is a point
