Answer:

11.4 x 10 ^ 6

Step-by-step explanation:

First, you have to convert 3.8 x 10^5 out of scientific notation. To do that, multiply 3.8 * 10^5, you'll get 380,000. This is the weight of each whale.
Now multiply the weight of each whale times 30. 380,000 * 30 = 11,400,000
Convert back to scientific notation. 11.4 x 10^6

Suppose that the total cost of flatiron TVs is given by the function TC(Q) = 500Q + 300 dollars, where Q is the number of TVs pr

Harrizon [31]

The value of TC(10) is 5300 Dollars

Given function is TC(Q) = 500Q +300 dollars

We need to calculate the value for TC (10)

As we know that the equation given is TC(Q) = 500Q + 300 dollars

Q is the number of TVs produced

Therefore, The value of Q is 10 for TC(10)

Substituting the value of Q

in the total cost of flatiron TVs given by function TC(Q) = 500Q + 300 dollars That Q= 100,

TC(10) = 500(10)+300 dollars

∴ TC (10) = 5000+300 dollars

∴ TC (10) = 5300 dollars

Hence the value of TC(10) is 5300 Dollars

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

AlekseyPX

Answer:

No Solution

Step-by-step explanation:

If you grouped like terms, you would get $n+(-n)+5-10=1$

Both <em>n's</em> would cancel each other out.

I hope this helps! (If it's wrong, then tell me, I'll try to find the correct answer...)

( 6m + 3 )( m - 2 ) A) 4m 2 - 2m - 20 B) 4m 2 - 20 C) 4m 2 + 18m + 20 D) 6m 2 - 9m - 6

dybincka [34]

Answer:

D

Step-by-step explanation:

So we have the expression:

$(6m+3)(m-2)$

Use the distributive property and distribute:

$=(6m+3)(m)+(6m+3)(-2)$

Distribute:

$=(6m^2+3m)+(-12m-6)$

Combine like terms:

$=6m^2+3m-12m-6\\=6m^2-9m-6$

The correct answer is D
