what is the shape and direction of f(x)=(x+7)(x+11)
Answers
Given:
The function is
[tex]f(x)=(x+7)(x+11)[/tex]
To find:
The shape and direction of the given function.
Solution:
We have,
[tex]f(x)=(x+7)(x+11)[/tex]
It can be written as
[tex]f(x)=x^2+11x+7x+77[/tex]
[tex]f(x)=x^2+18x+77[/tex]
It is a quadratic function and the power of [tex]x[/tex] is 2 so the graph of this function is a vertical parabola.
The leading coefficient is positive so the parabola opens upward.
Therefore, the given function is a vertical parabola that opens upward.

Which car traveled the farthest on
1 gallon of gas? Show your work.
Answers
explanation:
car A = 302 mi / 10 gal = 30.2 miles per gallon
car B = 174 mi / 5 gal = 34.8 miles per gallon

so since car c had the highest unit that means it travelled the farthest per gallon.

American Vending supplies vended food to a large university. Because students often kick the machines out of anger and frustration, management has a constant repair problem. The machines break down in a mean of 3 hours with a standard deviation of 3 hours. One repair worker can service one machine in a mean of 2 hours with a standard deviation of 2 hours. Currently, TWO repair workers are hired. Average flow time (W) was calculated as 2.305 from the posted queueing template. --- Average down machines in the entire system (L) are ___.
Answers
Answer:
0.77
Step-by-step explanation:
From the information given:
The breakdown time (a)= 3 hours
The breakdown rate (λ) = 1/a = 1/3
Average flow time in the system (W) = 2.305 hours
For the entire system;
The average down machines L = Wλ
= 2.305 × (1/3)
= 0.77

Answer:
1. they're vertical angles but the The missing angle is 140
2. there's no relationship being displayed because there's no image
3 theyre vertical angles
4 is 51
5 is 41
6 is 59
Step-by-step explanation:
All you need to do to find the missing angles is subtract from whatever. so the first one is a straight line so all you would do is 180-40 for the one that kind of looks like an x just know they're going to be the same angle when they're like that and for number four you can see it's a 90° angle so you subtract 90 - 39 so that you can get the answer that way

-1 = 2x
x = -1/2
y = 3(-1/2) + 7
y = -3/2 + 7
y = 5.5
x = -0.5 ; y = 5.5
Answer:
x = [tex]-\frac{1}{2}[/tex] y = 5.5
Step-by-step explanation:
substitution method
3x + 7 = 5x + 8
subtract 3x from both sides
7 = 2x + 8
subtract 8 from both sides
-1 = 2x
divide each side by 2
x = [tex]-\frac{1}{2}[/tex]
substitute the x in either equation
y = 3(-1/2) + 7
y = -1.5 + 7
y = 5.5
or
y = 5(-1/2) + 8
y = -2.5 + 8
y = 5.5
