The line passes through the point (-4,1) and is perpendicular to the line y=1/2x-4.
Answers
Answer:
y=-2x-7
Step-by-step explanation:
lines are typically written in y=mx+b form, where m is the slope and b is the y intercept
we are given the line y=1/2x-4
perpendicular lines are negative and reciprocal; if the slopes are multiplied together, the result is -1
so to find the slope of the new line, use this formula:
1/2m=-1
multiply by 2
m=-2
so the slope is -2
here's the equation so far, written in y=mx+b form
y=-2x+b
we need to find b
because the line passes through the point (-4,1), we can use it to solve for b
substiute -4 as x and 1 as y
1=-2(-4)+b
1=8+b
-7=b
so b is -7
therefore the line is:
y=-2x-7

Bill washes his mom's car once every 2 weeks and gets paid $20.00 each time. How much does he earn in 22 weeks?

Answers
Answer:
Bill earns $220.00 in 22 weeks.
Step-by-step explanation:
If he is paid 20 dollars every 2 weeks for a car wash, we need to find out how many he gets for 22 weeks.
20 dollars = 2 weeks, to find 22, multiply both of the values by 11 to get to 22.
11(2 weeks = 20 dollars)
22 weeks = 220.
The amount of money earned in 22 weeks is $220.
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The amount for each car wash = $20
Number of car wash in two weeks = 1
Now,
Number of car washes in 22 weeks.
= 22 / 2
= 11
Now,
The amount earned in 11 car washes.
= 11 x 20
= $220
Thus,
Amount earned in 22 weeks is $220.

When a water-cooled nuclear power plant is in operation, oxygen in the water is transmuted to nitrogen-17. After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level.
Required:
Write a differential equation that expresses the rate of change in the radiation level in terms of the radiation level.
Answers
Answer:
The differential equation is [tex]\frac{dR}{dt} = -kR[/tex]
Step-by-step explanation:
Differential equation for the rate of change in radiation level:
Radiation level is R.
Rate of change indicates that the radiation level R varies in function of time t, which mathematically means that we have:
[tex]\frac{dR}{dt}[/tex]
After the reactor is shut down, the radiation from the nitrogen-17 decreases in such a way that the rate of change in the radiation level is directly proportional to the radiation level.
Rate of change is k. Decreases means that k is negative. Proportional to the radiation level of R means that -k multiplies R. So the differential equation is:
[tex]\frac{dR}{dt} = -kR[/tex]

cost = 6 x 90 = $540
3) find the cost of 0.25 in^3
90 : 4 = 22.5
