In terms of π, what is the area of the circle? A) 25π cm2 B) 100π ft2 C) 625π cm2 D) 1000π cm2
Answers
9514 1404 393
Answer:
C) 625π cm^2
Step-by-step explanation:
The area of a circle is given by ...
A = πr²
where r is the radius. The radius is half the diameter, so is 25 cm. The area is ...
A = π(25 cm)² = 625π cm²

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

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

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.

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]

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]
