Answer:

After 1 second, the ball will reach a maximum height of 16 feet

Step-by-step explanation:

The height of the ball after t seconds: h(t) = -16t^2 + 32t

The graph of this quadratic function is parabola which opens downwards. The vertex of a quadratic equation is the maximum or minimum point on the equation's parabola

t = -b/2a = -(32)/2(-16) = -32/-32 = 1 second

then

h(t) = -16(1)^2 + 32(1) = -16 + 32 = 16

After 1 second, the ball will reach a maximum height of 16 feet

ZB=<br> Round your answer to the nearest hundredth.<br> A<br> 4<br> B<br> с<br> 3
Mice21 [21]

Answer:

Step-by-step explanation:

The opposite side to angle B is 4. It is the line AC. AC is not connected in any way to <B

The adjacent side is one of the two sides making up <B. It is 3.

Tan(B) = opposite / adjacent

Tan(B) = 4/3

<B = tan-1(4/3)

<B = 53.13

Pentagon PQRST and its reflection, pentagon P'Q'R'S'T', are shown in the coordinate plane below:
Ad libitum [116K]
<span>I have graphed the given coordinates of both pentagons. The reflection was across the y-axis where coordinates of Pentagon PQRST (-x,y) resulted to Pentagon P'Q'R'S'T' (x,y). The line of reflection between the pentagons was x = 0. Line of reflection is the midway between the pre-image and its reflection.</span>

If y = 3x+b intersects y= mx +3 at (2, 3), find the value of b and m.
Darina [25.2K]

Answer:

The value of b is -3 and m is 0.

Step-by-step explanation:

You have to substitute the coordinates into both equation in order to find m and b value :

Find m,

y = mx + 3

At (2,3),

3 = m(2) + 3

3 - 3 = 2m

2m = 0

m = 0

Find b,

y = 3x + b

At (2,3),

3 = 3(2) + b

b + 6 = 3

b = 3 - 6

b =  - 3
