What is the slope for a line that is perpendicular to the line y = 4x + 8?
Answers
Answer:
m2 =1/4
Step-by-step explanation:
m1 . m2 = 1
m1 is given 4 then
4.m2 =1
4.m2/4 =1/4
m2 = 1/4
Hello there!
The slopes of perpendicular lines are opposite reciprocals.
So, if one line has a slope of 4, then the slope of the line perpendicular to it is the opposite of 4 flopped over (-1/4)

Two angles in a triangle are 30 degrees and 40 degrees. Find the missing angle measure. Please show your math work step by step and don't forget the unit. 40° 30
Answers
Answer:
110
Step-by-step explanation:
Hello There!
If you didn't know the rule about angles in a triangle is that they have a sum of 180
So we can find the measure of the missing angle by subtracting the given angles (in this case 30 and 40) from 180
so the missing angle = 180 - 30 - 40
180 - 30 = 150
150 - 40 = 110
so the missing angle = 110
Two gyms open their memberships to the public. Compare the gyms by calculating and interpreting the average rates of change from Week 1 to Week 3.
From Week 1 to Week 3, Gym A membership increases at an average rate of _ people per week, and Gym B membership increases at an average rate of _ people per week. So, Gym _ membership is growing faster.
Answers
Answer:
Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Step-by-step explanation:
To find the average membership in Gym A is simple. To get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks. So, Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so subtract 204 by 80 and you get 124. Divide 124 by 2 because the difference between Week 1 to 3 is 2. Then we get 62 some Gym B gets 62 average members per week. Hope this helps. Gym A gets 52 people per week and Gym B gets 62 people per week. So, Gym B is growing faster.
Gym A gets 52 people per week and Gym B gets 62 people per week hence, Gym B is growing faster.
What are average?The average can be calculated by dividing the sum of observations by the number of observations.
To determine the average membership in Gym A is simple.
Therefore, to get 72 to 124, we need to subtract them getting 52, this is the same for the other weeks.
Gym A gets 52 members per week. Gym B is a bit more complex, each week has to be constant so,
204 -80 = 124.
Now Divide 124 by 2 because the difference between Week 1 to 3 is 2.
Then we get;
62 some Gym B gets 62 average members per week.
Hence, we can conclude that Gym A gets 52 people per week and Gym B gets 62 people per week.

One shape is approaching a poor from the east traveling west at 15 mph and its presently 3 miles east east of the port I second ship is already left the poor traveling to the north at 10 mph and is presently 4 miles north of the port at this instant what is the rate of change of distance between the two ships are they going to close your more for their apart
Answers
Answer:
DL/dt = 17 mph
Step-by-step explanation:
The ships and the port shape a right triangle
Ship going west ( x-direction) is traveling at 15 mph
Ship going north (y-direction) is traveling at 10 mph
The distance L between ships is:
L² = x² + y²
Tacking derivatives on both sides of the equation with respect to time
we get
2*L*DL/dt = 2*x*Dx/dt + 2*y*Dy/dt (1)
In that equation we know:
Dx/dt = 15 mph
Dy/dt = 10 mph
At the moment ship traveling from the east is at 3 miles from the port
then x = 3 m and the other ship is at 4 miles north
then by Pythagoras theorem
L = √ 3² + 4² L = 5
By substitution in equation 1
2*5*DL/dt = 2*3*15 + 2*4*10
10* DL/dt = 90 + 80
DL/dt = 170 / 10
DL/dt = 17 mph

Step-by-step explanation:
This question didn't provide much information to begin with. But since I got the same question as well, I'll help.
First off, we're given g(0) = -2.
Looking from the choices we're given, we're most likely going to have to choose an answer that makes most sense.
'g(x) = 0' doesn't make sense with this function because in 'g(0) = -2' we can see the our y-intercept is -2, not 0.
Another answer we're given is a table. Looking at the data, it doesn't match with the equation we're given.
Another answer choice we're given are multiple points that form a linear function. The points on the graph, however, don't match with 'g(0) = -2. Considering this is graph is showing a linear line, the point that would go with the function 'g(0) = -2 is (-2,0). In this answer choice, we don't see a point at either options.
This leaves us with the graph that displays a exponential line. We can however, see that there's a point that does match with this equation. That point is (0,-2). Considering this graph is showing an exponential line, one of the points for our function 'g(0) = -2' would be (0,-2).

Felicia paid $2,879 for a new wall oven with her credit card. Felicia’s credit card has an APR of 13.89%, compounded monthly. It took Felicia seven years of identical monthly payments to pay for her oven, and she made no other purchases with her card until it was paid off. Over the ten years that she kept the oven, it used an average of $2.97 per week in electricity. Between the electricity and the interest, which component of the lifetime cost of the oven was greater, and how much greater was it? (Round all dollar values to the nearest cent.)
a.
The interest cost $94.12 more than the electricity.
b.
The interest cost $1,638.52 more than the electricity.
c.
The electricity cost $1,334.60 more than the interest.
d.
The electricity cost $463.32 more than the interest.
Answers
Answer:
A. The interest cost $94.12 more than the electricity.
Step-by-step explanation:
2.97 x (10 years- 52 weeks in a year= 520) = 1544.40
P= PV x i / 1- (1+i)^-n
PV= 2879
I= .1389/12
N= 84 (7 years x 12)
53.78 x 84 = 4517.52
4517.52 - 2879 = 1638.52
1638.52 - 1544.40 = 94.12
