Answer:
(t + 6)(t - 6)
Step-by-step explanation:
(t - 6)(t + 6)
(t . t) + (t . (6) + ((-6) . t) + ((-6) . 6)
= t² - 6t + 6t - 36
= t² - 36
so,
t² - 36 = (t + 6)(t - 6)

Combine the like terms to simplify x + 4 - 5x - 2
Answer:
-1
Step-by-step explanation:
what you would start by doing is subtract x from 5 which gives it -6x. then, you would add the 2 to the 4 which cancels out the negative 2. so it should look like 6=-6x, then you would divide 6 by -6 which gives your answer as -1

im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]
What is the variance of the data set (4,6,7,10)
Answer:
4.6875Step-by-step explanation:
Given data set
(4,6,7,10)To find
VarianceSolution
The Variance is defined as the average of the squared differences from the mean.The mean is:
x = (4 + 6 + 7 + 10)/4 = 6.75The variance is:
σ² = [(4 - 6,75)² + (6 - 6.75)² + (7 - 6.75)² + (10 - 6.75)²]/4 = 4.6875How many solutions does 4x + 5 = 6(x + 3) - 20 - 2x have? Show your work.
Answer:
X∈∅
Step-by-step explanation:
4x + 5 = 6(x + 3) - 20 - 2x
distribute the 6
4x+5=6x+18-20-2x
collect like terms
4x+5=4x+18-20
4x+5=4x-2
cancel equal terms
5=-2
statment is false for any value of x

Round 94584 to the nearest hundreds
Answer:
94600
Step-by-step explanation:
A hundred has 2 zeroes. To round a number to the nearest hundreds, just look at the last 2 digits (84). If it is 5 or bigger, add 1 digit (as I did in this exercise) and so it becomes 94600.

FIRST CORRECT ANSWER GETS BRAINLIEST! CALCULATE THE SLOPE FOR INTERVAL A.
Answer:
60
Step-by-step explanation:
The slope is going to be rise over run which is feet/seconds
from (0,0) to (600,10) which is a the line rises up 600 feet and runs 10 seconds
so it is just 600/10 which is 60
