X/7.5=62
x=62x7.5
x=465

Okay, so I would multiply 62*7.5 to get 465.

To check the solution, make sure it follows the rules as in the word problem.

If you divide 465 by 7.5 you do get 62, so the solution is 465.

Mathematically, the equation would be

x
-     = 62
7.5
I would multiply x/7.5 by 7.5/1 (to cancel it out) and 62/1  by 7.5 which is basically the same solution as above.

Answer:6018

Step-by-step explanation:

Given Sequence

-282-266-250-234.....

It represent an A.P. with

first term a=-282

common difference d=16

So sum of 51 term

S_n=\frac{n}{2}[2a+(n-1)d]

S_{51}=\frac{51}{2}\times [2\times (-282)+(51-1)16]

S_{51}=\frac{51}{2}\times [-564+800]

S_{51}=\frac{51}{2}\times [236]

S_{51}=51\times 118

S_{51}=6018

The cost to produce a product is modeled by the function f(x) = 5x2 − 70x 258, where x is the number of products produced. compl
ad-work [718]

The minimum cost to produce the product is $7.

What are functions?

  • A function from a set X to a set Y allocates exactly one element of Y to each element of X.

To determine the minimum cost:

We have to determine the minimum cost of producing this product.

Since f(x) = 5x^{2} -70x+258.

Now, consider the equation 5x^{2} -70x+258= 0.

Dividing the above equation by 5, we get

x^{2} -70x/5+258/5=0\\x^{2} -14x+258/5=0

Now, considering the coefficient of 'x', dividing it by '2' and then adding and subtracting the square of the number which we got after dividing.

Since the coefficient of 'x' is 14, and half of 14 is '7'.

So, adding and subtracting from the above equation.

x^{2} -14x+(7)^{2} -(7)^{2}+258/5=0\\x^{2} -14x+49 -49+258/5=0\\(x-7)^{2} -49+258/5=0\\(x-7)^{2} +258-245/5=0\\(x-7)^{2} +13/5=0\\5(x-7)^{2} +13=0

Now, we have to determine the minimum cost to produce the product.

Since f(x) = 5x^{2} -70x+258.

f'(x) = 10x-70

Now, let f'(x)=0

10x-70=0\\10x=70

Therefore, x=7

Now, consider which is greater than 0.

Therefore, x= 7 is the minimum cost.

Michel is building an in-ground swimming pool. it has a length of 16 feet, a width of 10 feet, and a depth of 8 feet. How many c
jonny [76]
The swimming pool is a <span>rectangular prism</span> (which means it's a 3D rectangle). To find the volume of a rectangular prism you multiply Length x Width x Height.

In this case that would mean 16*10*8 (height and depth are the same in this problem).

16*10*8=<span>1280 ft</span>³<span>
