Answer:

3x + 3

Step-by-step explanation:

Combine like terms. Like terms are terms with the same amount of variables.

10x - 7x + 3

(10x - 7x) + 3

Subtract:

10x - 7x = 3x

Remember to bring the constant down.

3x + 3 is your answer.

A water balloon is tossed into the air. The function h(x)=-0.5(x-4)squared +9 gives the height, in the feet, of the balloon from
NNADVOKAT [17]

Answer:

No, the maximum height that the balloon can reach is 9ft.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

The function h(x) =-0.5(x-4)² +9, is a Quadratic Function in the Vertex form.

Vertex form: f (x) = a(x - h) 2 + k

Where:

  • (h, k) is the vertex of the parabola-
  • h is the horizontal shift (how far left, or right, the graph has shifted from x = 0).  
  • k represents the vertical shift (how far up, or down, the graph has shifted from y = 0).  

In this case a = -0.5, it means that the parabola opens downward and has a maximum point at the vertex.

So, the maximum height that the balloon can reach is k=9ft.

9 ∠ 12

The balloon will not hit the ceiling 12 ft above the pool.

Feel free to ask for more if needed or if you did not understand something.

a cylinder has radius 1.6 meters. it’s volume is 95 cubic meters. find it’s height to the nearest tenth of a meter
erastova [34]
H = 11.81 m


v= π r2 h

h = v/ π r2 = 95/ π 1.6(2)* = 11.81228m or just 11.81


*(2) is squared


hope this helped haha

How many dots are in the 4th step?
Mkey [24]

Answer:

32

Step-by-step explanation:

if you look at the diagram the dot goes up 1 each. It also makes another row which makes 4 rows total. Since 3 contains 7 dots and 3 rows we would do 8 in 4 rows. 8 x 4 is 32.

Hope this helped!

For the function f(x)=x^2, what effect will multiplying f(x) by 1/2 have on the graph?
erma4kov [3.2K]
For the function f ( x ) = x² we have the new function f 1 ( x ) = 1/2 x².
f ( x ) = a · x²
- If |a| < 1   the graph is compressed vertically by a factor of a.
- If |a| > 1  the graph is stretched vertically by a factor of a.
