A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, can the company build 20 child bikes and 6 adult bikes in a week. (2 points) No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer:
answer rounded up is -31.84
Step-by-step explanation:
So first, square root of 6 is 2.4494, and then you times that by 2, and then you do square root of 54 which equals to 7.34846, and then you times 5 by that, and then you do 2 times square root of 6 minus 5 times square root of 54. Hope it helps

to find the slope the equation is the secony - the first y over the second x- the first x so 2-7 is -5 and 3-7 is -4 so it would be -5/4
Expressed as a percentage, how many more avocados does the city of
Phoenix consume per year compared to Denver? Phoenix - 120 Denver - 75
Answer:
In Phoenix they consume 60% more avocados than in Denver.
Step-by-step explanation:
Given that in Denver they consume 75 units of avocados, while in Phoenix they consume 120 units of said fruit, to determine the percentage difference between the consumption of both cities it is necessary to perform the following calculation:
75 = 100
120 = X
((120 x 100) / 75) = X
(12,000 / 75) = X
160 = X
160 - 100 = 60
Therefore, in Phoenix they consume 60% more avocados than in Denver.
In Phoenix they consume 60% more avocados than in Denver.
We have given that in Denver they consume 75 units of avocados, while in Phoenix they consume 120 units of said fruit, we have to determine the percentage difference between the consumption of both cities it is necessary to perform the following calculation
Suppose 75 = 100
[tex]120 = x[/tex]
[tex]100\times 120=75x[/tex]
divide both side by 75
[tex](120 \times 100) / 75) = X[/tex]
[tex](12,000 / 75) = X[/tex]
[tex]160 = X[/tex]
[tex]160 - 100 = 60[/tex]
Therefore, in Phoenix they consume 60% more avocados than in Denver.

5. Open Response Monique wants to rent
online movies. Movies Plus charges a
one-time fee of $20 plus $5 per movie.
Movies-To-Go charges $7 per movie. For how
many movies is the cost of renting movies
from Movies Plus and Movies-To-Go the
same?
Answer:
I'm going to say Movies-To-Go because this is an easy question.
Step-by-step explanation:
movies plus charges more than movies to go and your asking for which one is cheaper so movies to go is the answer.
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is 10 movies.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Movies plus:
One time fee = $20
Cost per movie = $5
We can write an equation for the total cost T for x movies:
T = 20 + 5x _____(1)
Movie-to-go:
Cost per movie = $7
We can write an equation for the total cost T for x movies:
T = 7x _____(2)
Now,
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is:
From (1) and (2),
20 + 5x = 7x
20 = 7x - 5x
20 = 2x
x = 20/2
x = 10
Thus,
The number of movies at which the cost of renting movies
from Movies Plus and Movies-To-Go is the same is 10 movies.

The equation of the piecewise defined function f(x) is below. What is the value of f(1)?
The value of the f(1) should be -1 when the equation of the piecewise defined function f(x).
Calculation of the value of f(1):here first we are required to determine which expression to use for f(1). The first function does not involve 1, because it is <, and not ≤
And,
The second functions involved 1, because it has a ≤ that meaning greater than or equal to, so this is the function we must use.
So, it can be like
f(1) = -1
= -(x^2)
= -(1)
= -1
hence,
The value of the f(1) should be -1 when the equation of the piecewise defined function f(x).

====================================================
Work Shown:
Plug (x,y) = (3,2) into the F(x,y) function
[tex]F(x,y) = 2x^2 + 4y^2\\\\F(3,2) = 2(3)^2 + 4(2)^2\\\\F(3,2) = 34\\\\[/tex]
Next, find the gradient and plug in (x,y) = (3,2)
[tex]F(x,y) = 2x^2 + 4y^2\\\\\\\nabla F(x,y) = \Big< \frac{dF}{dx}, \frac{dF}{dy}\Big>\\\\\\\nabla F(x,y) = \Big< 4x, 8y \Big>\\\\\\\nabla F(3,2) = \Big< 4*3, 8*2 \Big>\\\\\\\nabla F(3,2) = \Big< 12, 16 \Big>\\\\\\[/tex]
This means,
[tex]z = \nabla F(3,2) \cdot \left(\vec{x} - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \left(\big< x,y \big> - \big< 3, 2 \big>\right) + F(3,2)\\\\\\z = \nabla F(3,2) \cdot \big< x-3,y-2 \big> + F(3,2)\\\\\\z = \big< 12,16 \big> \cdot \big< x-3,y-2 \big> + 34\\\\\\z = 12(x-3)+16(y-2) + 34\\\\\\z = 12x-36+16y-32 + 34\\\\\\z = 12x+16y-34\\\\\\[/tex]
As a way to help check, note how plugging (x,y) = (3,2) into the last equation for z leads to z = 34. This helps confirm that we have the correct equation because the point (3,2,34) must be on F(x,y) and also on z since the plane is tangent to the F(x,y) curve at this point.

Answer:
I assume that the figure your figure is like this:
The Area of the shaded Region is 36π .
What is a Circle ?A circle is a round shaped figure whose all the point lie in the same plane.
It is given that Area of the shaded region needs to be found in the figure attached
Radius of the outer circle is 10
and Radius of the inner circle is 8
The area of the shaded region = Area of the outer circle - area of the inner circle
Area of a circle = πr²
r is the radius of the circle.
Area of the outer circle = π(10)²
Area of the outer circle = 100π
Area of the inner circle = π (8)²
Area of the inner circle = 64 π
Area of the shaded Region = 100π - 64 π
Area of the shaded Region = 36π
Therefore the Area of the shaded Region is 36π .
