Answer:
8/x+2 or [tex]\frac{8}{2+x}[/tex]
Step-by-step explanation:
To answer, carefully read the question and pick up on key words like "sum." To begin, we know that "sum" means addition, therefore the sum of 2 and a number (which will be replaced by the variable x) is equivilent to 2 + x. Furthermore, we know that 8 is being divided by the sum. So, the final expression should be [tex]\frac{8}{2+x}[/tex] . Good luck!
Which of the following is true of the composition F(G(H(X)))?
A. The function G(F(H(x))) depends on G(H(x)).
B. The function F(G(H(x))) depends on H(G(x)).
C. The function H(G(F(x))) depends on G(F(x)).
D. The function F(G(H(x))) depends on G(H(x)).
SUBMIT
Answer:
D. F(G(H(x))) depends on G(H(x))
Step-by-step explanation:
A function depends on its argument (the stuff in parentheses after the function name). The argument of function F in F(G(H(x))) is G(H(x)).
F(G(H(x))) depends on G(H(x))
__
Answer choices A and C do not make any statement about the given composition. Answer choice B shows a composition (H(G(x))) that has no relation to the argument of function F.
Answer: D. F(G(H(x))) depends on G(H(x))

Help please V/5 = 3/7 v=
Answer:
v = 15/7, or 2.14
Step-by-step explanation:
Find a common denominator, or multiply both denominators by each other, and well as the numerator.
v/5 = 3/7 can be written as 7v/35 = 15/35
multiplying both sides with 35, we are left with 7v = 15
v = 15/7, or 2.14
For the quadratic function f(x) = x2 + 6x +11:
a. Use the idea of completing the square to write it in graphing form.
Step-by-step explanation:
Make f(x) = 0
[tex] {x}^{2} + 6x + 11 = 0[/tex]
First, we move the constant term to the right hand side of the equality sign.[tex] {x}^{2} + 6x = - 11[/tex]
Then, we half the coefficient of x and square our result.[tex]( \frac{6}{2} ) ^{2} = 3 ^{2} = 9[/tex]
Now, we add the result to the both sides of the equation.[tex] {x}^{2} + 6x + 9 = - 11 + 9[/tex]
We can see that x²+6x+9 = (x+3)² {Try factorizing}Therefore,(x+3)²= -2
(x+3)²+2= 0
f(x)= (x+3)²+2
Which is the f(x) in graphing form.

The Happy Widget Company has a fixed cost of $1,378 each day to run their factory and a variable cost of $1.83 for each widget they produce.
Create a linear model for their daily cost.
How much does it cost them to produce 267 widgets?
The linear model for the daily cost is C(x) = $1378 + $1.83(x).
The cost of producing 267 widgets is $1,866.61
What is the cost of producing 267 widgets?
Fixed cost is the cost the remains constant with the number of widgets produced. Variable cost increases with the number of widgets produced. Daily cost is the sum of fixed cost and variable cost.
Fixed cost = fixed cost + (variable cost x number of widgets)
C(x) = $1378 + $1.83(x).
C(x) = $1378 + $1.83(267) = $1,866.61

How do you find the radian of any given degree.
To convert any given angle from the measure of degrees to radians, the value has to be multiplied by π/180.
hope it helps...!!!
Answer:
there are 2pi radians in a circle
there are also 360 radians in a circle
let r = radians and d = degrees
2*pi*r=360*d
2pi/360*radians = degrees
(pi/180)*radians = degrees
CAN SOMEBODY HELP IM LOST WITH THIS THIS EQUATION
Answer:
1. C(d)=0.69x+25.95
2. C(d)=0.69(57)+25.95
[0.69 times 57 is 39.33]
= 65.28 dollars
3. 136.3 miles
Step-by-step explanation:
For the first question....
Since this is a function, we have to start with C(d). Even if you drive 0 miles, you still have to pay $25.95 just for renting the truck, so that is constant. For every mile you drive, you pay $0.69. Since we don't know how far anyone is going to drive, we will put 'x' as the amount of miles driven. The number of miles driven (x) multiplied by 0.69 will be the cost of that. The final function would be C(d)=0.69x+25.95.
For the second question....
We know the general function now, so driving 57 miles would mean substituting "x" for 57, and doing the multiplication (if necessary), 0.69 times 57 equals 39.33 (the dollar amount for driving 57 miles, not including the starting fee of 25.95)
Doing the math, you can get $65.28 (39.33+25.95).
For the third question...
If we have a budget, we know that C(d) is the amount of money spent, so we'll substitute the budget (120) for that. We'll solve the equation for x from there, and should get 136.3 miles (rounded to the nearest hundredth).
Hope this helps!

Look at the given triangles.
A. Write an expression in the simplest form for the perimeter of each triangle.
B. Write another expression in simplest form that shows the difference between the perimeter of the larger triangle and the perimeter of the smaller triangle.
C. Find the perimeter of each triangle when x=3
Blue: P=4x +2+7x +7+5x-4 --> 16x +9-4=16x +5
Red: P=x+3+2x - 5 + x + 7 --> 4x + 10 - 5 = 4x + 5
Difference between the perimeter:
(16x + 5) - (4x + 5) = 16x + 5 - 4x - 5 = 12x
Perimeter when x = 3
Blue : 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17
The answers are explained in the solution.
What is perimeter?The perimeter of an object is given by adding the side lengths of the object.
Given are two triangles, we need to find their perimeters and then the difference and the value of the perimeter when x = 3,
Blue:
P = 4x +2 +7x + 7+5x-4
= 16x +9-4 = 16x +5
Red:
P = x+3+2x - 5 + x + 7
= 4x + 10 - 5 = 4x + 5
Now,
The difference between the perimeter:
(16x + 5) - (4x + 5)
= 16x + 5 - 4x - 5
= 12x
The perimeter when x = 3
Blue: 16x + 5 ⇒ 16(3) + 5 = 48 + 5 = 53
Red: 4x + 5 ⇒ 4(3) + 5 = 12 + 5 = 17
Hence, the perimeters of the given triangle are 53 and 17 respectively.

Answer:
56503
Step-by-step explanation:
this grows exponentialy so at the start it would be 50,000 growing by 5% every ten years. but since there is only 2 ten years in 25 years we must cut the percent in half making 2.5%

(50,000×5%)+50,000= 52500
