Answer:

36.9 m

Step-by-step explanation:

h(t) = -4.9t² + 25t + 6

At t = 3:

h(3) = -4.9(3)² + 25(3) + 6

h(3) = -44.1 + 75 + 6

h(3) = 36.9

After 3 seconds, the ball will have a height of 36.9 meters.

Whats the surface area of this figure
irakobra [83]

Answer:

504

Step-by-step explanation:

The area of the base is 14 x 14 which is 196

The area of one triangle is 1/2 x base length x height which is:

1/2 x 14 x 11 = 77

So the area of one triangle is 77. The area of all the triangles is the same and there are 4 triangles.

So the surface area is

196 + 77 + 77 + 77 + 77 = 504

The difference of two numbers is equal to 0.6. Their quotient is also 0.6. What are the numbers?
sveticcg [70]
Let one number be x and the other number be y.

The 2 equations are:
x - y = 0.6    --------------- (1)
x/y = 0.6      --------------- (2)

From equation (1):
x - y = 0.6
x = 0.6 + y     --------------- Sub into (2)

\dfrac{0.6 + y}{y} = 0.6

0.6 + y= 0.6y

y - 0.6y = - 0.6

0.4y = - 0.6

y = -0.6 ÷ 0.4

y = -1.5

Sub y = -1.5 into (1):

x - y = 0.6

x - (-1.5) = 0.6

x  + 1.5 = 0.6

x = 0.6 - 1.5

x = - 0.9

Answer: The numbers are -0.9 and -1.5

Y = -6x + 19<br> -6x + 4y = 16
Fantom [35]

Answer:

the answer is 2

Step-by-step explanation:

y=-6x+19

-6x+4y=16

-6x+4(-6x+19)=16

-6x-24x+76=16

-30x+76=16

-30x=16-76

-30x=-60

if there is - in both side we should cut them

30x=60

x=60/30

x=2

Hope it is helpful for you
