What is the value of 7 ^−3 ^ −1 for = −2 and = 4?

andrey2020 [161]

Answer:

d. −7/32

Step-by-step explanation:

The expression that we have to evaluate in this problem is:

$7x^{-3}y^{-1}$

We have to evaluate this expression for:

x = -2

y = 4

We start by rewriting the expression by rewriting it using the following:

$a^{-n}=\frac{1}{a^n}$

So the expression can be rewritten as

$7x^{-3}y^{-1}=\frac{7}{x^3 y}$

Now we observe that:

$(-2)^3=(-2)(-2)(-2)=-8$

Therefore, by substituting x = -2 and y = 4 into the expression, we find:

$\frac{7}{(-2)^3\cdot 4}=\frac{7}{-8\cdot 4}=-\frac{7}{32}$

Brian works at the oil factory. He gets a $45 per day. He gets a 10% pay increase. He wirks 24 days in a month. How much more mo

Artist 52 [7]

Answer:

Net increment = $108

Step-by-step explanation:

Current wage rate for Brian = $45 per day

number of days Brain is working = 24

Total earning in a month = $45 x 24 = $ 1080

Total increment = 10% of $45

= 0.10 x $45 = $4.5

New wage rate for Brain = $45=$4.5= $49.5

No. of working days = 24

New earning per month = $49.4 x 24 = $1188

Total increment in the earning = $1188- $ 1080

= $108
