Kriste respone is wrong
<em><u>Solution:</u></em>
Given that,
Kristen was asked to write each of the numbers in the expression 80,000 x 25 using exponents
Her response was (8 x 10 to the power of 3) x 5 to the power of 2
No, the response of Kristen is wrong
Let us first understand about exponents
An exponent refers to the number of times a number is multiplied by itself
Given expression is:
Here, 80000 has 4 zeros
Therefore, it can be raised as 10 power 4
<em><u>Thus the expression becomes:</u></em>
Also, 25 can be written as 5 power 2
Thus given expression is written as (8 x 10 to the power 4) x 5 power to the power 2
Thus Kristen respone is wrong, because he has raised 10 to power 3
ANSWER
The radius is 4
EXPLANATION
The given equation is:
We complete the square to get the expression in standard form:
We factor using perfect squares to get:
This implies that,
Comparing to
The radius is r=4
Answer:
Step-by-step explanation:
a). Given equation is y = 3x - 4
Table for the input-output values is,
x -1 0 1 2 3
y -7 -4 -1 2 5
Now we can plot these points on the graph (graph attached).
b). Equation is y = -2x + 3
Table for the input-output values will be,
x -1 0 1 2 3
y 5 3 1 -1 -3
Answer:
Option D.
Step-by-step explanation:
==>27
r = 3
9r
which means 9x3 = 27.
answer: x = 1/2
<u>explanation</u>
subtract 3x from both sides
4x+8=10
subtract 8 from both sides
4x=2
divide both sides by 4
x=2/4
simplify
x=1/2 OR x=.5
hope i helped!
