Answer:
The answer is
[tex] \huge y + 7 = - \frac{3}{4} (x - 16) \\ [/tex]
Step-by-step explanation:
To find an equation of a line in point slope form when given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question we have the final answer as
[tex]y + 7 = - \frac{3}{4} (x - 16)[/tex]
Hope this helps you

1. F & G industries manufacturers a motor that is marketed with a warranty that guarantees it will be replaces free of charge if it fails within the first 13,000 hours of operation. On average, F & G, motors operate for 15,000 hours with a standard deviation of 1,250 hours before failing. The number of operating hours before failure is approximately normally distributed. a. What is the probability that a motor will have to be replaced free of charge
Answer:
The value is [tex]P(X < 13000) =0.054799[/tex]
Step-by-step explanation:
From the question we are told that
The number of hours considered is [tex]x= 13000 \ hours[/tex]
The population mean is [tex]\mu = 15000\ hours[/tex]
The standard deviation is [tex]\sigma = 1250\ hours[/tex]
Generally the the probability that a motor will have to be replaced free of charge is mathematically represented as
[tex]P(X < 13000) = P(\frac{ X - \mu }{\sigma } < \frac{13000 - 15000}{1250} )[/tex]
[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]
[tex]P(X < 13000) = P(Z<-1.6 )[/tex]
From the z table the probability of (Z<-1.6 ) is
[tex]P(Z<-1.6 ) = 0.054799[/tex]
So
[tex]P(X < 13000) =0.054799[/tex]
Among the thirty largest U.S. cities, the mean one-way commute time to work is 25.8 minutes. The longest one-way travel time is in New York City, where the mean time is 38.5 minutes. Assume the distribution of travel times in New York City follows the normal probability distribution and the standard deviation is 7.2 minutes. Use Appendix B.3. What percent of the New York City commutes are for less than 26 minutes
Answer:
4.093%
Step-by-step explanation:
Here, we want to calculate the proportion of Newyork commutes that are less than 26 minutes
We start by calculating the z-score
z = (x - mean)/SD
here;
x = 26
mean = 38.5 minutes
SD = 7.2 minutes
Thus, we have;
z = (26-38.5)/7.2
z = -1.74
We proceed to use the standard normal distribution table to get the probability of P(x < -1.74)
That will be 0.04093
So the proportion will be this in %
That will be 4.093%
A stone is dropped into a lake, creating a circular ripple that travels outward at a speed of 70 cm/s. Find the rate at which the area within the circle is increasing after each of the following. (a) after 1 s $$40 cm2/s (b) after 4 s cm2/s (c) after 6 s cm2/s
Answer:
(a) 9800π cm²/s
(b) 39200π cm²/s
(c) 58800π cm²/s
Step-by-step explanation:
As we know,
The area of circle is:
[tex]A= \pi r^2[/tex]
[tex]\frac{dA}{dt}=2 \pi r\frac{dr}{dt}[/tex]
The given value is:
[tex]\frac{dr}{dt} =70 \ cm/s[/tex]
Now,
(a)
After 1 second,
r = 70×1
= 70 cm
⇒ [tex]\frac{dA}{dt}=2\pi(70)\times (70)[/tex]
[tex]=9800 \pi \ cm^2/s[/tex]
(b)
After 2 second,
r = 70×4
= 280 cm
⇒ [tex]\frac{dA}{dt}=2\pi \ (280)\times (70)[/tex]
[tex]39200\pi \ cm^2/s[/tex]
(c)
After 6 seconds,
r = 70×6
= 420 cm
⇒ [tex]\frac{dA}{dt}=2\pi \ (420)\times (70)[/tex]
[tex]58800\pi \ cm^2/s[/tex]
The rate will be:
(a) 9800 π cm²/s
(b) 39200 π cm²/s
(c) 58800 π cm²/s
Circle:A circle seems to be a closed object or structure generated by tracing a point that travels together in plane at quite a constant distances from either a specific location.
According to the question,
Speed, [tex]\frac{dr}{dt}[/tex] = 70 cm/s
We know,
The area of circle:
→ A = πr²
[tex]\frac{dA}{dt}[/tex] = 2πr[tex]\frac{dr}{dt}[/tex]
(a) After 1 s, the rate be:
r = 70 × 1
= 70 cm
[tex]\frac{dA}{dt}[/tex] = 2π(70) × 70
= 9800 π cm²/s
(b) After 2 s, the rate be:
r = 70 × 4
= 280 cm
[tex]\frac{dA}{dt}[/tex] = 2π(280) × 70
= 39200 π cm²/s
(c) After 6 s, the rate be:
r = 70 × 6
= 420 cm
[tex]\frac{dA}{dt}[/tex] = 2π(420) × 70
= 58800 π cm²/s
Thus the response above is correct.

One side of a triangle is one-fourth the longest side. The third side is
8 feet less than the longest side. The perimeter is
118. Find all three sides.
The sides have lengths of______ ,___________ , and________ feet.
Answer:
Step-by-step explanation:
Let's call A the longest side. The others triangle sides are B and C.
We know that B = (1/4)*A and C = A - 8
The triangle's perimeter is: A + B + C = 118
Substituting the values of sides B and C, we have:
A + (1/4)A + (A-8) = 118
Adding common terms: (2 + 1/4)A = 118 + 8
(9/4)A = 126 then, A = 56 feet
B = (1/4)A = 14 ft
C = A - 8 = 48 feet

Randal's dad is installing a new pool in their backyard. The pool is a square and has an
area of 121ft? Randal's dad will then build a 4 ft wide deck to surround the pool.
What is the outside perimeter of the deck?
Answer:
76 feet.
Step-by-step explanation:
The side of the pool = square root of 121 = 11 feet.
With the deck the length of 1 side will be 11 + 2 *4 = 19 feet.
There are 4 sides in the outside perimeter so the answer:
= 4 * 19 = 76 feet.
