Explain why (–4x)0 = 1, but –4x0 = –4.

1 answer:

5 0

Any number raised to power of 0 is 1.
In (-4x)^0, because of the parenthesis, the whole number is being raided to 0, which gives 1.
But in -4x^0, only x is being raised to 0, thus -4x^0 = -4(1) = -4.

Answer:

4^4·6^5·7^7 = 1,639,390,814,208

Step-by-step explanation:

Taking the cube root multiplies each exponent by 1/3.

((4^12)(6^15)(7^21))^(1/3) = (4^(12/3))·(6^(15/3))·(7^(21/3)) = (4^4)(6^5)(7^7)

12. Currently, there are 350 students in the seventh grade at Winchester

sweet [91]

Answer:

Winchester Heights Middle School plan to have 385 students in the upcoming school year.

Step-by-step explanation:

Total number of students in the seventh grade at Winchester Heights Middle School = 350

For the upcoming school year, they are planning to increase the number of seventh graders by 10%.

Rate of increase = r = 10% = 0.1

Formula : $N(t)=N_0(1+r)^t$

Where $N_0$ = initial population = 350

r = rate of increase =0.1

N(t)=Population after t years

t = time in years

So, Population after 1 year = $350(1+0.1)^1 =385$

Hence Winchester Heights Middle School plan to have 385 students in the upcoming school year.
