The function h is given by h ( t ) = ( 1 − t ) ( 8 + 16 t ) models the height of a ball in feet, t seconds after it is thrown.

Answer:

  • zeros: t = 1, t = -1/2
  • no: the domain of the function is t ≥ 0
  • 8 feet

Step-by-step explanation:

The zeros are the values of t that make the factors zero.

  1 -t = 0   ⇒   t = 1

  8 +16t = 0   ⇒   t = -8/16 = -1/2

The equation is used to model height after the ball is thrown. We don't expect it to be a good model before the ball is thrown (t < 0), so the zero in that region is extraneous.

Only the positive zero is in the function's domain, so that is the only one that is meaningful.

__

When t = 0 (at the time the ball is thrown), the function value is ...

  h(0) = (1 -0)(8 +0) = 8

The ball is thrown from a height of 8 feet.

Please solve
raketka [301]

Step 1. Simplify 1/3x to x/3

-x/3 > 5

Step 2. Multiply both sides by 3

-x > 5 * 3

Step 3. Simplify 5 * 3 to 15

-x > 15

Step 4. Multiply both sides by -1

x < -15

Your answer is A.

An unfair coin with​ Pr[H] = 0.75 is flipped. If the flip results in a​ head, a student is selected at random from a class of si
Agata [3.3K]

Answer:

72.73% probability of selecting a​ girl, given the flip resulted in​heads

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Coin resulted in heads

Student is selected at random from a class of six boys and sixteen girls.​

Desired outcomes:

16 girls, so D = 16

Total outcomes:

16+6 = 22, that is, 22 students, so T = 22

Probability:

P = \frac{16}{22} = 0.7273

72.73% probability of selecting a​ girl, given the flip resulted in​heads

A regular pentagon has side lengths of 10 cm and an
Fittoniya [83]

Answer: 172 square centimeters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Area of a pentagon (A) = 1/2× 5s × a

Where:

s : side of the pentagon

a: apothem

Replacing with the values given and solving for A (area):

A =1/2 x (5 x10) x 6.88

A = 172 square centimeters.

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