What is the value of (-14^0)^-2?
posledela

Answer:

The value of given expression is 1.

Step-by-step explanation:

The given expression is

(-14^0)^{-2}

If a is a real number, then a^0=1.

(-1)^{-2}                 [\because a^0=1]

Using exponent property we get,

(-1)^{-2}=\frac{1}{(-1)^2}                    [\because a^{-n}=\frac{1}{a^n}]

(-1)^{-2}=\frac{1}{1}

(-1)^{-2}=1

Therefore the value of given expression is 1.

Please help me with this question. Thank you so much everyone.
LiRa [457]

Answer:

1159

Step-by-step explanation:

She wants to read 1000 pages per week for five weeks.

So in total she wants to read 1000 * 5 = 5000 pages.

The first three weeks she read 894 pages per week.

So during the first three weeks she read a total of 894 * 3 = 2682 pages.

We want to find how many pages she must read per week for the last two weeks to reach her goal.

Goal: 5000 pages

Pages read so far: 2682

Weeks remaining: 2

To find how many pages she must read for the last two weeks we simply subtract the number of pages she read during the first 3 weeks (2682 ) by her goal ( 5000 )

5000 - 2682 = 2318

So she must read 2318 pages during the last 2 weeks.

If we want to find the amount of pages she must read per week during the last 2 weeks to reach her goal, we simply divide the amount of pages she must read during the last few weeks to reach her goal ( 2318 ) by the number of remaining weeks ( 2 )

2318 / 2 = 1159

So for the last two weeks she must average 1159 pages per week.
