Josh hit a baseball straight up into the air. The equation below describes the
height of the ball (h), in meters, as a function of time (t) in seconds.
h(t) = -9.8t2 + 30t + 1.5
What is the height of the ball after 3 seconds?

Answers

Answer 1

Answer:

3.3 meters

Step-by-step explanation:

h(3)=-9.8(3)^2+30(3)+1.5

=-88.2+90+1.5

=3.3

Answer:

YW = 6

Step-by-step explanation:

a^2 + b^2 = c^2

x^2 + 8^2 = 10^2

x^2 + 64 = 100

x^2 + 64 - 64 = 100 - 64

x^2 = 36

√x^2 = √36

x = 6

Line YW is equal 6 feet

Step-by-step explanation:

I used the pythagorean theorem

1. 8 squared plus b squared equals 10 squared

2. 64 plus b squared equals 100

3. 100 - 64 equals 36

4. B squared equals 36

5. square root both sides

6. b equals 6 feet

Step-by-step explanation:

multiply each side by 27 to get rid of the denominator

3(3y-6)= -9(4-2y) is what is left

solve

9y=18

y=2

Step-by-step explanation:

Suppose an object is launched from ground level directly upward at 57.4 f/s Write a function to represent the object’s height over time.

Answers

Answer: p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t

Step-by-step explanation:

We can suppose that the only force acting on the object is the gravitational force, then the acceleration of the object will be equal to the gravitational acceleration.

Then we can write:

a(t) = -32 ft/s^2

Where the negative sign is because this acceleration is downwards.

Now, to get the vertical velocity of the object, we need to integrate over time to get:

v(t) = (-32 ft/s^2)*t + v0

where t represents time in seconds and v0 is the constant of integration, and in this case, is the initial vertical velocity.

In this case, the initial velocity is 57.4 ft/s upwards, then the velocity equation is:

v(t) = (-32 ft/s^2)*t + 57.4 ft/s

To get the position equation we need to integrate over time again, to get:

p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t + p0

Where p0 is the initial height of the object, as it was launched from the ground, then the initial position is p0 = 0ft.

then the position equation (that is the function that represents the height of the object as a function over time) is:

p(t) = (1/2)*(-32 ft/s^2)*t^2 + (57.4 ft/s)*t

p(t) = (-16 ft/s^2)*t^2 + (57.4 ft/s)*t

Answers

Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.

Step-by-step explanation:

1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.

2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.

Step-by-step explanation:

first, we multiply both sides by 7, un order to get the variable by itself. this is the important step.

-56 = n

then, we just simply swap the sides in order to get the variable on the left. (not necessary, just looks like a proper equation that way.)

n = -56

work:

-8 = n/7
