Solution:

The expression is

\frac{5-4}{4^{-3}}=1 \times 4^3= 4 \times 4 \times 4=64→→→Used law of indices here ,\frac{1}{a^{-m}}=a^m and\\\\ a^m = a \times a \times a (\text{m times})

Option D: 64 is right choice.

Find the midpoint of the line segment with the endpoints A and B.
zavuch27 [327]

Answer:

<h2>( 6 , 7 )</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M = (  \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )\\

From the question we have

m = ( \frac{2 + 10}{2} \:  , \:  \frac{6 + 8}{2} ) \\  =  (\frac{12}{2}  \: , \:  \frac{14}{2} ) \:  \:  \:  \:  \:  \:  \:

We have the final answer as

<h3>( 6 , 7 )</h3>

Hope this helps you

Approximate the real zeros to the nearest tenth: a.-1.6, 1.6 c.-2.6, 2.6 b.-2, 1 d .-1.6, 2.6 Please select the best answer from
Mariana [72]

Answer:

You didn't give the expression whose zero you want to find. From the options you wrote, the expression has two zeros, this means it is a quadratic expression.

I will however explain how to find the zero of a quadratic expression.

Step-by-step explanation:

An expression is called quadratic, if the highest degree of the variable is 2, no more, no less. It is of the form: ax² + bx + c, where a, b, and c are constants.

The zeros of a quadratic expression are the values that make the expression vanish, that is equal to zero.

Example: Find the zeros of 2x² - 6x + 4

First, equate the expression to zero

2x² - 6x + 4 = 0

Next, solve for x

2x² - 2x - 4x + 4 = 0

2x(x - 1) - 4(x - 1) = 0

(2x - 4)(x - 1) = 0

(2x - 4) = 0

Or

(x - 1) = 0

2x - 4 = 0

2x = 4

=> x = 4/2 = 2

Or

x - 1 = 0

x = 1

Therefore, the zeros of the polynomial are 1 and 2.
