Answer:
The rocket's maximum height will be 1424 feet.
It will reach that height in 4 seconds.
It will reach the ground in 8 seconds.
Step-by-step explanation:
One easy way to find the peak is to find the derivative and solve for zero:
h(t) = -16t² + 128t + 1680
To find the derivative of each term in that format, you simply multiply the coefficient by the exponent, and reduce the exponent by one. In the case of terms with no variable, they disappear. That gives us:
h'(t) = -32t + 128
This derivative describes the rate of change of h with respect to t, so to find the peak, we simply need to solve it for zero:
0 = -32t + 128
32t = 128
t = 4
So the maximum height occurs when t = 4. Let's plug it in to the original equation:
h(t) = -16t² + 128t + 1680
h(4) = -256 + 512 + 1680
h(4) = 1424
So the rocket's maxiumum height is 1424 feet.
And we've already answered the second question, it happens at 4 seconds.
Also, the amount of time going up will be the same as the amount of time going down, which means that it will reach the ground in twice that time, or 8 seconds.

6 + 3 (10× - 22) could someone please help me solve this
Answers
Answer:
x = -2
Step-by-step explanation:
6 + 3(10x-22)
3 * 10x = 30x
3 * -22 = -66
6 + 30x = -66
-66 + 6 = -60
30x = -60
-60/30 = -2
x = -2

Missing part:
What is the probability that an international flight leaving the US is delayed in departing given that the flight is a transpacific flight?
Answer:
[tex]P(D|P) = 0.50[/tex]
Step-by-step explanation:
Given
[tex]P(D) = 0.26[/tex]
[tex]P(P) = 0.50[/tex]
[tex]P(D\ and\ P) = 0.13[/tex]
The question illustrates conditional probability and it is represented as:
P(D|P)
This is then calculated as:
[tex]P(D|P) = \frac{P(D\ and\ P)}{P(D)}[/tex]
So, we have:
[tex]P(D|P) = \frac{0.13}{0.26}[/tex]
[tex]P(D|P) = 0.50[/tex]

a grilled chicken salad at a popular fast food restaurant contain 650 mg of sodium.which is 27% of recommended daily amount.what is the total recommended daily amount of sodium?
Answers
Answer:
286.34 mg
Step-by-step explanation:
Let the recommended amount is x.
ATQ,
A grilled chicken salad at a popular fast food restaurant contains 650 mg of sodium which is 27% of recommended daily amount.
Mathematically,
[tex]27\%\ of\ x=650 \\\\\dfrac{27}{100}x=650\\\\x=\dfrac{650\times 100}{227}\\\\x=286.34\ mg[/tex]
So, the recommended amount of sodium is equal to 286.34 mg.
Let x and y be two positive numbers whose sum is 175 and (x+3)(y+4) is a maximum
Answers
Answer:
Step-by-step explanation:
x+y = 175
y = 175 - x
f(x) = (x+3)(y+4)
= x(175-x) + 3(175-x) + 4x + 12
= 175x - x² + 525 - 3x + 4x + 12
= -x² +176x + 537
f'(x) = -2x + 176
maximum when x = 88
y = 175-x = 87

Find x. (leave answer in simplest radical form) *

Answer:

Step-by-step explanation:
The small right triangle at left is a 30-60-90 triangle.
x is the long leg, opposite the 60-deg angle.
The hypotenuse has length 4sqrt(3)
The ratio of the lengths of its sides is:
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
The short leg measures half the hypotenuse.
short leg = (1/2)4sqrt(3) = 2sqrt(3)
The long leg measures the short leg times sqrt(3)
long leg = 2sqrt(3) * sqrt(3)
long leg = 6
x = long leg = 6
