<h2>Answer:</h2>

The amount the jacket will cost on sale is:

                    $ 112.5

<h2>Step-by-step explanation:</h2>

It is given that:

A  $150 leather jacket is going on sale for 25% discount.

i.e. Original price of jacket= $ 150

This means that the cost of jacket is:

cost of jacket will be=Original price of jacket-25% of original price of jacket.

i.e.

cost of jacket will be= 150-25% of 150

cost of jacket will be= 150-0.25×150

cost of jacket will be= $ 112.5

100%-25% = 75%

75% = 0.75

150 * 0.75 = 112.50

it will sell for $112.50

Which algebraic expression is equivalent to this expression?<br><br> 6(3x-1)+9x
rusak2 [61]

Answer:

27x-6

Step-by-step explanation:

To distribute 6(3x-1) properly, 6 needs to be multiplied with 3x and -1.

6*(-1)=-6,

3x*6=18x.

Without simplifying, the answer we get from this is 18x+9x-6. 18x+9x=27x, so the algebraic expression equivalent to 6(3x-1)+9x is 27x-6.

(1 point) Consider the function f(x)=2x3−9x2−60x+1 on the interval [−4,9]. Find the average or mean slope of the function on thi
OlgaM077 [116]

Answer: c = 4.97 and c = -1.97

Step-by-step explanation: <u>Mean Value Theorem</u> states if a function f(x) is continuous on interval [a,b] and differentiable on (a,b), there is at least one value c in the interval (a<c<b) such that:

f'(c) = \frac{f(b)-f(a)}{b-a}

So, for the function f(x) = 2x^{3}-9x^{2}-60x+1 on interval [-4,9]

f'(x) = 6x^{2}-18x-60

f(-4) = 2.(-4)^{3}-9.(-4)^{2}-60.(-4)+1

f(-4) = 113

f(9) = 2.(9)^{3}-9.(9)^{2}-60.(9)+1

f(9) = 100

Calculating average:

6c^{2}-18c-60 = \frac{100-113}{9-(-4)}

6c^{2}-18c-60 = -1

6c^{2}-18c-59 = 0

Resolving through Bhaskara:

c = \frac{18+\sqrt{1740} }{12}

c = \frac{18+41.71 }{12} = 4.97

c = \frac{18-41.71 }{12} = -1.97

<u>Both values of c exist inside the interval [-4,9], so both values are mean slope: c = 4.97 and c = -1.97</u>

The first term in a sequence of numbers is 1/2
Andrei [34K]

Answer:

The correct answer is C. The 4th term is 11.

Step-by-step explanation:

Since the next term is one more than twice the previous, we can calculate it by the following expression:

a_{n} = 2*a_{n-1} + 1

So the second term is:

a_2 = 2*\frac{1}{2} + 1\\a_2 = 2

The third term:

a_3 = 2*2 + 1\\a_3 = 5

And the fourth term:

a_4 = 2*5 + 1\\a_4 = 10 + 1 = 11

The correct answer is C. The 4th term is 11.
