rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, a in seconds, by the given equation. Using this equation, find out
the time at which the rocket will reach its max, to the nearest 100th of a second.
y=16x^2+ +225x+79

Answers

Answer 1

Answer:

7.03 seconds

Step-by-step explanation:

First, you need to differentiate the equation (The derivative of y represents the rocket's velocity):

y' = 32x + 225

Then, set y' to 0 and solve for x

0 = 32x + 225

x = 7.03s

simplify the following expression
1/2 (18t) +2t(9)-12​

Answers

Answer:

The answer is 27t - 12.

Step-by-step explanation:

1) Remove parentheses.

[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]

2) Use this rule: a/b × c/d = ac/bd.

[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]

3) Simplify 1 × 18t to 18t.

[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]

4) Simplify 18t/2 to 9t.

[tex]9t + 2t \times 9 - 12[/tex]

5) Simplify 2t × 9 to 18t.

[tex]9t + 18t - 12[/tex]

6) Collect like terms.

[tex](9t + 18t) - 12[/tex]

7) Simplify.

[tex]27t - 12[/tex]

Thus, the answer is 27t - 12.

If 70% of college students say they have a job what is the probability that 3 randomly selected college students say they have a job?

Answers

Answer: 0.343

Step-by-step explanation:

Probability of college students that say they have a job = 70%

Number of randomly selected college students = 3

The probability that 3 randomly selected college students say they have a job will be:

= (70/100)³

= 0.7 × 0.7 × 0.7

max has 3 5/6 pounds of potting soil. She uses 2 3/8 pounds to fill a pot. how many pounds of potting soil does max have left?​

Answers

Answer:

1 11/24 pounds left

Step-by-step explanation:

For this question, find the common denominators of the fraction to add them.

A common multiple of 6 and 8 is 24.

So, 5*4 = 20  6*4 = 24

3 20/24 of potting soil initially

Then, 3*3 = 9   8*3 = 24

2 9/24 used

To find how many pounds are left:

3 20/24 - 2 9/24 = 1 11/24

The diagram shows a wedge ABCDEF.

The base of the wedge is a horizontal rectangle measuring 60cm x 40cm

Answers

9514 1404 393

Answer:

  77.3 cm

Step-by-step explanation:

The distance FA is the diagonal of rectangle ABFE. We know the length AB, so we need to find the length BF. That is found using the trig relation ...

  cos(25°) = BC/BF

  BF = BC/cos(25°) ≈ (60 cm)/0.906308 ≈ 66.203 cm

Then the diagonal length FA is found using the Pythagorean theorem:

  FA = √(AB² +BF²)

  FA = √(40² +66.203²) ≈ √5982.79 ≈ 77.349 . . . cm

The diagonal length FA is about 77.3 cm.
