Hey there!

To find if the first two answers are true, all you need to do is count the number of variables of each type in each equation. This number will be your exponent, since it's the number of times you will multiply that variable by itself. 

For your first answer, there are 6 x's. This means that when you multiply the x's together, it will equal x⁶. This is correct. 

For your second answer, there are 7 A's and 5 B's. This will equal A⁷B⁵. This is correct. 

The last two answers are a bit different. In order to simplify an equation like the ones you've been given, you'd need to put all of your terms in parenthesis in order to say that all of the terms within them must be multiplied by what is outside of the parenthesis. This means that:

(bc)⁶ = (b)⁶(c⁶) = b⁶c⁶, which is correct

xyz⁵ = xyz⁵ ≠ x⁵y⁵z⁵, which is not correct

Your answer will be your fourth option. Hope this helped you out! :-)

What is the best estimate for the product of 289 and 7
Katarina [22]
I would estimate it as (300 x 7) = 2100 

Then I would subtract (11 x 7) + 77 from that to get the exact answer of 2023 

~~~~~~~~~~ 
I didn't use a calculator or paper. The 'trick' is to notice that 289 = (300 - 11)

What point is 2/3 of the distance from point A(3, 1) to point B(3, 19)?
8_murik_8 [283]

Answer: (3, 13)

Step-by-step explanation:

If we let the point be P, then AP:BP=2:1.

P=\left(\frac{(2)(3)+(1)(3)}{2+1}, \frac{(2)(19)+(1)(1)}{2+1} \right)=(3, 13)

H(t)= (t+3)^2 + 5
oee [108]

Answer:

The average rate of change for the given function in the interval (-5, -1) is 0 (zero)

Step-by-step explanation:

The average rate of change of a function over an interval is the quotient between the difference between the function evaluated at the ends of the interval divided by the length of the interval. That is for our case:

the average rte of change of h(t) in the interval (-5, -1) is:

\frac{h(-1)-h(-5)}{-1+5}

so we find:

h(-1)=(-1+3)^2+5=2^2+5=4+5=9\\and\\h(-5)=(-5+3)^2+5=(-2)^2+5=4+5=9

then the average rate of change becomes:

\frac{h(-1)-h(-5)}{-1+5}=\frac{9-9}{4} =\frac{0}{4} =0
