find (f*f)(3) f(x)=x^2-x

Answers

Answer 1

fof(x) = f(x^2 - x) = (x^2 - x)^2 - (x^2 - x)
f(3) = (9 - 3)^2 - (9 - 3)
f(3) = 6^2 - 6
f(3) = 36 - 6 = 30

I wouldn't want to bet the farm on this. If you get another answer that is reasonable, take it.

Answer 2

To find (f * f)(3) for the function f(x) = x² - x, we calculate f(3) to get 6, and then square it to get 36.

The question is asking to calculate (f * f)(3) given the function f(x) = x² - x. To do this, we find the value of f(x) for x=3 and then square that result. First, let's compute f(3).

f(3) = (3)² - (3) = 9 - 3 = 6.

Now, we find (f * f)(3), which means f(3) * f(3).

(f * f)(3) = f(3) * f(3) = 6 * 6 = 36.

Therefore, the solution to (f * f)(3) is 36.

Jenny's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Jenny 5.25
per pound, and type B coffee costs 4.15
per pound. This month, Jenny made 150
pounds of the blend, for a total cost of
642.60. How many pounds of type B coffee did she use?

Answers

In order to know the answer, you would have to set up a system of equations:

Given that type A coffee costs $4.15 per pound
(4.15x)
Given that type B coffee costs $5.25 per pound
(5.25y)
And that the total cost of it all was $642.60

[tex]4.15x + 5.25y = 642.60[/tex]
Also, the amount of pounds, represented by x and y add up to 150 pounds total:

[tex]x + y = 150[/tex]

A+B=167lbs
A=167lbs-B
$4.35A+$5.70B=$846.60 Substitute for A
$4.35(167lbs-B)+$5.70B=$846.60
$726.45-$4.35B+$5.70B=$846.60 Subtract $726.45 from each side.
$1.35B=$120.15 Divide each side by $1.35.
B=89 lbs
ANSWER: The mix contained 89 pounds of Type B coffee.
CHECK:
167lbs-89lbs=78 lbs She used 78 pounds of Type A coffee.
$4.35A+$5.70B=$846.60
$4.35(78)+$5.70(89)=$846.60
$339.30+$507.30=$846.60
$846.60=$846.60

Write a polynomial expression for the perimeter of a rectangle whose sides have the following lengths. Length: x2+3x-5 Width: 3x2-2x+6 A. 8x2+8x+2 B.8x2+2x+2 C.4x2+x+1 D. 4x2-5x+1

Answers

Final answer:

The perimeter of the rectangle with given dimensions is represented by the polynomial 8x^2 + 2x + 2, which corresponds to option A.

Explanation:

To determine the perimeter of a rectangle, we need to add up all sides of the rectangle. The formula for the perimeter (P) of a rectangle is P = 2(length) + 2(width). Given the length is x2 + 3x - 5 and the width is 3x2 - 2x + 6, we would calculate the perimeter as follows:

P = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)

Expanding this expression:

P = 2x2 + 6x - 10 + 6x2 - 4x + 12

Combining like terms gives us:

P = (2x2 + 6x2) + (6x - 4x) + (-10 + 12)

P = 8x2 + 2x + 2

So the correct polynomial expression for the perimeter of the rectangle is option A: 8x2 + 2x + 2.

Final answer:

The polynomial expression for the perimeter of the rectangle with given side lengths is 8x^2 + 2x + 2.

Explanation:

The perimeter of a rectangle is given by the formula P = 2l + 2w, where l represents the length and w represents the width. For the lengths provided, the length (l) is x2 + 3x - 5 and the width (w) is 3x2 - 2x + 6. To find the polynomial expression for the perimeter, we will multiply both the length and the width by 2 and then sum them:

Perimeter (P) = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)

On simplifying:

P = 2x2 + 6x - 10 + 6x2 - 4x + 12

P = (2 + 6)x2 + (6 - 4)x - (10 - 12)

P = 8x2 + 2x + 2

Therefore, the correct polynomial expression for the perimeter is 8x2 + 2x + 2, which corresponds to option B.

If the constant c is chosen so that the curve given parametrically by ct, c 2 16 t 2 , 0 â‰¤ t â‰¤ 3 , is the arc of the parabola 16y = x 2 from (0, 0) to (8, 4), find the coordinates of the point p on this arc corresponding to t = 2.

Answers

Final answer:

The coordinates of point p corresponding to t = 2 on the specified parametric curve, when matching the arc of the parabola 16y = x^2, are (8, 2).

Explanation:

The student is asking to find the coordinates of the point p corresponding to t = 2 on the curve defined parametrically by ct, [tex]c^2/16[/tex] × [tex]t^2[/tex] where c is chosen such that the curve becomes the arc of the parabola 16y = x² from (0, 0) to (8, 4).

To find c, we match the parametric equations to the standard form 16y = x², which implies c = 4 because for any point (x, y) on the parabola, y must equal [tex]x^2/16[/tex].

Substituting t = 2 into the corrected parametric equations x = 4t and y = 4 · [tex](t^2/16)[/tex], we obtain the coordinates of point p as (8, 2).

How far does a ball, hit from a height of 3 feet at a speed of 120 feet per second and an angle of 30 degrees, go before it hits the ground? Round your answer to the nearest integer.

Answers

The time of flight ends once the height of the ball hits the ground. First we look at the ball's upward trajectory. Its initial vertical velocity is (120 ft/s)(sin 30) = 60 ft/s. Since gravity is -32 ft/s^2, this means that the ball will fly upward for 60/32 = 1.875 s. By then, it will be at a height of:
h = h0 + vi*t - 0.5gt^2 = 3 ft + (60 ft/s)(1.875 s) - 0.5(32 ft/s^2)(1.875)^2 = 59.25 ft
So the time of its downward flight is solved by:
59.25 = 0.5(32)t^2
t = 1.924 s
Total time of flight = 1.875 + 1.924 = 3.799 s
The ball's horizontal velocity is constant at (120 ft/s)(cos 30) = 103.923 ft/s.
Multiplying this by the time of flight of 3.799 s gives a total distance of 395 ft.

It is 76 miles from waterton to middleton. it is 87 miles from middleton to oak hill. driving directly, it is 134 miles from waterton to oak hill. it is 39 miles rom oak hill to jackson. if juan drives from waterton to middleton then from middleton to oak hill, and finally home to waterton, how many miles does he drive?

Answers

297 miles would be the answer. It is simple addition.

Final answer:

Juan drives a total of 297 miles if he travels from Waterton to Middleton, then to Oak Hill, and back to Waterton.

Explanation:

The student is asking to calculate the total number of miles driven by Juan starting from Waterton to Middleton, then from Middleton to Oak Hill, and then returning home to Waterton.

To find the total distance traveled by Juan, we simply need to add the individual distances of each leg of his trip.

Waterton to Middleton: 76 milesMiddleton to Oak Hill: 87 milesOak Hill to Waterton (directly): 134 miles

By adding these distances, we get the total miles Juan drives:

Total miles driven = 76 + 87 + 134 = 297 miles

Solve for x and y.

y=x^2-5x+1
x+y=-2

Answers

y = x² - 5x + 1
x + y = -2

substitute the first equation into the second one....

x + x² - 5x + 1 = -2
x² - 4x + 1 = -2
add 2 on both sides to make the equation equal to 0.

x² - 4x + 3 = 0
factor this.

(x - 1)(x - 3) = 0
x = 1 , x = 3

to find the y values, you would have to substitute x = 1 and x = 3.
1 + y = -2 3 + y = -2
y = -3 y = -5

So your answers are
x = 1 , x = 3
y = -3, y = -5

at an airport it costs $7 to park for up to one hour and $5 per hour for each additional hour. let x represent the number of hours parked. write the function that modles the cost, C(x), of the parking x hours, where x is an integer greater then 1.

Answers

Answer:

C(X) = 7 + 5(X-1)

Step-by-step explanation:

So, the cost for parking from 0 to 1 hour is $7. Then, for one extra hour, from 1 to 2, you have to pay an additional $5. For another hour, from 2 to 3, an extra $5, and so on. So, lets make a quick table:

Hours Cost

[0-1] $7

(1-2] $7+$5

(2-3] $7+$5+$5

(3-4] $7+$5+$5+$5

So, for 1 hour the cost is $7, for 2 hours $12, 3 hours $17, 4 hours $22, and so on. We can see a pattern here: the cost for X hours is $7 plus $5 for each hour greater than 1. So we can write the cost function as:

C(X) = 7 + 5(X-1)

If X=2, 2 hours, the cost is:

C(2) = 7 + 5(2-1) = 7 + 5 = 12, so the function fits.

Notice that here I used the parenthesis in a (--] form, however, it could also be used in a [--) form. If the last is chosen, 2 hours would cost $17 instead of $12. The function would be C(X) = 7 + 5X.

As the statement does not specifies, any of this ways can be used.
