Inessa [10]3 years ago
5 0

Given:

Consider the given expression is:

\dfrac{7^{-1}}{7^{-2}}

To find:

The quotient of the given fraction value.

Solution:

We have,

\dfrac{7^{-1}}{7^{-2}}

It can be written as:

\dfrac{7^{-1}}{7^{-2}}=7^{-1-(-2)}            \left[\because \dfrac{a^m}{a^n}=a^{m-n}\right]

\dfrac{7^{-1}}{7^{-2}}=7^{-1+2}

\dfrac{7^{-1}}{7^{-2}}=7^{1}

\dfrac{7^{-1}}{7^{-2}}=7

Therefore, the value of the quotient is 7.

Note: Options B and C are same and both are correct.

Julian calculates the volume of a rectangular prism with the dimensions 3/4ft by 4 feet by 1/2 ft. His work is shown here.
lbvjy [14]

Answer:

He multiplied the denominators incorrectly

Step-by-step explanation:

we know that

The volume of a rectangular prism is given by the formula

V=LWH

we have

L=3/4 ft

W=5/1 ft

H=1/2

substitute

V=(3/4)(5/1)(1/2)= 3x5x1=    15

                           ₋₋₋₋₋₋₋₋    ₋₋₋₋ ft³

                           4x1x2=    8

                       

therefore

He multiplied the denominators incorrectly

What value of "p" will the pair of equations
Nikolay [14]

Answer:

9

Step-by-step explanation:

Slope is the same as coefficient of x

From the equation

3x+4y=12

Y=(-3/4)x+3

The slope for this eqn is -3/4

For this equation

Px+12y=30

12y=-p+30

Y= (-p/12)x +30/12

The slope is -p/12

To get p

-p/12=-3/4

P=9

Find all roots: x^3-7x^2-12x = 0
Pepsi [2]

Answer:

The roots are  0, 3 and 4.

Step-by-step explanation:

x^3-7x^2-12x = 0   Take out x:

x(x^2 - 7x - 12) = 0  Factor the expression in the brackets:

x(x - 3)(x - 4) = 0

x = 0 or x - 3 = 0 or x - 4 = 0, so

The roots are  0, 3 and 4.
