Answer:
The first one is 0, the second one is ARN (All real numbers)
Step-by-step explanation:
1. Anything raised to the "zeroth" power is always 1
2. Because 7 is being raised to the zeroth power, the number inside the parentheses becomes 1. Now x can equal anything, 1 times itself will always equal 1, no matter how many times you multiply them.
Answer:
-12x^5 + 14x^3 -2x^2 + 10x
Step-by-step explanation:
-2x(6x^4 -7x^2 +x-5) =
-12x^5 + 14x^3 -2x^2 + 10x
1) The best thing to do here is to divide the two weights of the buses and fin out what you need to multiply it by.
100/50= 2.
Therefore, you've got to multiply the amount of people by 2.
10*2= 20
Therefore, it takes 20 people to pull a 100 ton bus.
2) Here, you should work out what each one is worth. Half of 40 is 20.
one fourth of 20 is 5. Therefore, half of 40 is larger.
3) The best thing to do is to divide 32 by 8, and then multiply the number of degrees by this.
32/8=4
110*4= 440
Therefore, the ball rotates 440 degrees in 32 seconds.
4) the best thing to do is to find what one part is worth- and to do this, you have to add together the amount of roses and divide this by the total roses.
4+6= 10
50/10= 5
The roses are 6 parts yellow, therefore, 6*5= 30, there are 30 yellow roses.
Hope this helps :)
Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>
The amount of money after t years in simple interest is modeled by:

In which:
- r is the interest rate, as a decimal.
The interest earned is:

A bank loaned out $14000, in two parts, hence:

Part of it at the rate of 9% per year and the rest at 17% per year, hence:

The interest received in one year totaled $2000, hence:

Then:



Isolating
as a function of
, then we can replace on the equation for the first interest.



Then:






$13,872 was loaned at 9%.
