6 = 5 + 1, then (5 + 1) + 5 = 11, (5 + 5) + 1 = 11, 10 + 1 = 11

Calling a Math Genius!!! What is the incorrect Step?

Pie

When you divide something by 3/4, there's no way something can decrease, unless the number is a fraction below 3/4.

Since in Step 2, they divided 27 by 3/4, but ended up with 20 1/4, that means that they got step 2 wrong, because 27 / (3/4) is equal to 27 * 4/3 = 36

(This is because dividing by a fraction is the same thing as multiplying by the reciprocal of the fraction.)

So therefore they got Step 2 wrong.

Find the average rate of change of f ( x ) = 9 x 2 − 7 on the interval [ 2 , a ] . Your answer will be an expression involving a

aleksandrvk [35]

Answer:

9a + 18

Step-by-step explanation:

so the first step is to evaluate the value of f(2).

$f(2) = 9(2)^2-7\\f(2)=9(4)-7\\f(2)=36-7\\f(2)=29$

Now that we have this value we can use the slope formula (y2 - y1) / (x2 - x1) where y2 is f(a), y1 is 29, x2 is a, and x1 is 2

$\frac{f(a)-29}{a-2}\\\\\frac{(9a^2-7)-29}{a-2}\\\frac{9a^2-36}{a-2}$

Now from here we can use long division to simplify it further

$9a^2/a = 9a\\9a(a-2)=9a^2-18a\\(9a^2-36)-(9a^2-18a)\\18a-36\\\\18a/a=18\\18(a-2)=18a-36\\(18a-36)-(18a-36)\\0\\\\9a+18$

a juice company produced 8064 cartons of juice in 21 days each day they produced the same the same number of carton and delivere

pshichka [43]

Answer:

The each coffee shops receives 4 cases of juice everyday.

Step-by-step explanation:

The juice company produced 8064 cartons of juice in 21 days each day they produced the same number of cartons.

Therefore, each day the company produces $\frac{8064}{21} = 384$ cartons.

The juice company delivers those cartons in 16 areas of coffee shops.

So, each coffee shop receives $\frac{384}{16} = 24$ cartons of juice.

Now, the cartons were delivered in cases of six cartons per case and each coffee shop received an equal number of cases in each delivery.

Hence, each coffee shops receives $\frac{24}{6} = 4$ cases of juice everyday. (Answer)
