Answer:

64

Step-by-step explanation:

[using calculus] When the function h(t) reaches its maximum value, its first derivative will be equal to zero (the first derivative represents velocity of the ball, which is instantaneously zero). We have [tex]h'(t) = -32t + 48[/tex], which equals zero when [tex]t = 3/2 = 1.5[/tex]. The ball therefore reaches its maximum height when t = 1.5. To find the maximum height, we need to find h(1.5), which is 64 feet.

[without calculus] This is a quadratic function, so its maximum value will occur at its vertex. The formula for the x-coordinate of the vertex is -b/2a, so the maximum value occurs when t = -48/(2*16), which is 1.5. The maximum height is h(1.5), which is 64 feet.

Answer:

  A) domain: 0 ≤ n ≤ 10

  B) the height at the start of the study

  C) 0.431 cm per day, average growth rate

Step-by-step explanation:

A) The study started on day 0 and ended on day 10. A reasonable domain is ...

  0 ≤ n ≤ 10

__

B) The y-intercept of the graph of plant height is the height of the plant on day 0, the day the study started.

__

C) On day 3, the height was ...

  f(3) = 12·1.03^3 ≈ 13.1127 . . . cm

On day 10, it was ...

  f(10) = 12·1.03^10 ≈ 16.1270 . . . cm

Then the plant grew at an average rate of ...

  (16.1270 -13.1127) cm/(10 -3 days) ≈ 0.431 . . . cm/day

The average rate of change is the average rate of growth of the plant in the given period.

Answer:

13. [tex]D = 18[/tex]

14. [tex]S = (x, y + 6)[/tex]

Step-by-step explanation:

13.

Given

[tex]M = (-8,2)[/tex]

[tex]S = (10,2)[/tex]

Required

Determine the distance between M and S

Distance (D) is calculated using:

[tex]D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]

Where

[tex](x_1,y_1) = (-8,2)[/tex]

[tex](x_2,y_2) = (10,2)[/tex]

[tex]D = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]

[tex]D = \sqrt{(10 - (-8))^2 + (2 - 2)^2}[/tex]

[tex]D = \sqrt{(10 +8)^2 + 0^2}[/tex]

[tex]D = \sqrt{18^2 + 0}[/tex]

[tex]D = \sqrt{18^2}[/tex]

[tex]D = 18[/tex]

Hence, the distance between M and S is 18 units

14.

The coordinate of S and P are not given,

So, I'll just use (x,y) for P

i.e.

[tex]P=(x,y)[/tex]

Required

Determine the coordinates of S

If S is 6 units above P, then the coordinates of S is

[tex]S = (x, y + 6)[/tex]

i.e. we add the units to the y coordinate of P.

Step-by-step explanation:

3, 4 and 5 cant be a right triangle

Answer:

The sides are

6

inches,

8

inches and

10

inches

Explanation:

I'd suggest that the question should read 'The perimeter of a triangle is 24 inches. The longest side is 4 inches longer than the shortest side, and the shortest side is three-fourths the length of the middle side. How do you find the length of each side of the triangle?'

In this case the question can be answered. If

x

is the length of the middle side, then the shortest side is 3/4x and the longest side is 3/4x+4

x+3/4x+3/4x+4=24

10/4x=20

x=8

Then the shortest side is 6and the longest side is 10

Answer:

Step-by-step explanation:

(a) What is the probability of a fatal accident over a lifetime?

Suppose A be the event of a fatal accident occurring in a single trip.

Given that:

P(1 single auto trip in the United States result in a fatality) = P(A)

Then;

P(A) = 1/4011000

P(A) = 2.493 × 10⁻⁷

Now;

P(1 single auto trip in the United States NOT resulting in a fatality) is:

P([tex]\mathbf{\overline A}[/tex]) = 1 -  P(A)

P([tex]\mathbf{\overline A}[/tex]) = 1 - 2.493 × 10⁻⁷

P([tex]\mathbf{\overline A}[/tex]) = 0.9999997507

However, P(fatal accident over a lifetime) = P(at least 1 fatal accident in lifetime i.e. 46000 trips)

= 1 - P(NO fatal accidents in 46000 trips)

Similarly,

P(No fatal accidents over a lifetime) = P(No fatal accident in the 46000 trips) = P(No fatality on the 1st trip and No fatality on the 2nd trip ... and no fatality on the 45999 trip and no fatality on the 46000 trip)

= [tex][P(\overline A)] ^{46000} \ \ \ (since \ trips \ are \ independent \ events)[/tex]

= [tex][0.9999997507]^{46000}[/tex]

= 0.9885977032

Finally;

P(fatal accident over a lifetime) = 1 -  0.9885977032

P(fatal accident over a lifetime) = 0.0114022968

P(fatal accident over a lifetime) ≅ 0.0114

Answer:

Larger number = 32

Step-by-step explanation:

Smaller number = x

Larger number = y

y - x = 8    -----------(I)

3y = 4x  ---------------(II)

3y/4 = x

Plug in x = 3y/4 in equation (I)

[tex]y - \frac{3}{4}y = 8\\\\\frac{4}{4}y - \frac{3}{4}y = 8\\\\\frac{1}{4}y = 8\\[/tex]

 y = 8*4

  y = 32

Plug in y = 32 in equation (II)

3y = 4x

3*32 = 4x

4x = 3*32

x = [tex]\frac{3*32}{4}[/tex]

x = 3 *8

x = 24
