Claudio needs to buy gifts for 8 friends. He wants to give the same gift to all his friends and he plans to have the gifts wrapp
Blizzard [7]

Answer:

7.25

Step-by-step explanation:

In the question, the term at least means less than or equal to is represented by ≥

Let the cost of each gift = c

He is buying gifts for 8 friends = 8 gifts

Hence, our Inequality equation is written as:

(c + $1.50)× 8 ≥ $70

8c + 12 ≥ 70

8c ≥70 - 12

c ≥ 58/8

c≥ 7.25

Therefore, the amount Claudio needs to spend on each gift in order to receive free shipping is 7.25

kirill115 [55]
Answer: The are 39,070,080 different ways the DJ can play the first 6 songs.

We will use the Fundamental Counting Principle to find the answer. Simply determine the number of choices for each position and multiply.

For the first choice there are 21 choices. Then, the number is reduced by 1 each time.

So to get the answer, we have to multiply the numbers below:

21 x 20 x 19 x 18 x 17 x 16

Find the slope of the tangent line to f(x) = √(12-x) at x = -52
wariber [46]

Answer:

slope: -0.0625

Explanation:

To find slope of a function, we have to find the derivative of the function.

  • Here given the function:  f(x) = √(12-x)
<h3><u>Start deriving the equation</u>:</h3>

\rightarrow \sf \dfrac{dy}{dx} = \dfrac{d}{dx} ( \sqrt{12-x} )

\rightarrow \sf \dfrac{dy}{dx} = \dfrac{d}{dx} ( (12-x)^{\frac{1}{2} }} )

\rightarrow \sf \dfrac{dy}{dx} = \dfrac{1}{2} ( (12-x)^{\frac{1}{2}-1 }} )(-1)

\rightarrow \sf \dfrac{1}{2\sqrt{12-x}}\left(-1\right)

\rightarrow \sf -\dfrac{1}{2\sqrt{12-x}}

\bold{\star} <u>Tangent/Parallel Line Has Same Slope</u>

<u />

To find slope at x = -52, simplify insert x = -52 in derivative we found

\rightarrow \sf -\dfrac{1}{2\sqrt{12-(-52)}} \ = \ -\dfrac{1}{16}  \  \ = \  -0.0625
