Answer:
D. 5 x 10⁶ ÷ 6.6 x 10⁴Step-by-step explanation:
If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;
6.6 x 10^4 mi² = $5 X 10^6
1mi² = $x
Cross multiply;
$5 X 10^6 * 1 = 6.6 x 10^4 * x
6.6 x 10⁴ x = 5 X 10⁶
Divide both sides by 6.6 x 10⁴ to get x;
6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴
x = 5 x 10⁶ ÷ 6.6 x 10⁴
x = 0.76*10⁶⁻⁴
x = $0.76*10²
Hence the key strokes on a calculator will give the cost the United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴
Netflix used to charge $5 per DVD rental and a $10 membership fee. Plex used to charge $2 per DVD and a $60 membership fee. Which inequality best represents when the charges from Netflix are less than Plex?
Answer:
the charges from Netflix are less than Plex cause there's a 50 dollar gap for the member ship and for the DVD there's only a 3 dollar gap

Why all integers are not whole numbers?
Answer:
Integers -4, -3, -2, -1, 0, 1, 2, 3, 4… all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. For example, -5 is an integer but not a whole number or a natural number.

What is the distance between the two points (-5, 6) and (8,-4)?
Given parameters:
Coordinates of the two points = (-5, 6) and (8,-4)
Unknown:
Distance between the two points.
To find the distance between two points, use the expression below;
Distance ² = (x₂ - x₁)² + (y₂ - y₁)²
where;
(-5, 6) and (8,-4)
x₂ = 8 , x₁ = -5 , y₂ = -4 and y₁ = 6
Input the parameters and solve;
Distance² = (8-(-5))² + (-4 - (6))²
= 169 + 100
= 269
Distance = [tex]\sqrt269}[/tex] = 16.4
The distance between the two points is 16.4

Answer: -2
Step-by-step explanation:
Can someone please explain to me how to work this out?
Answer:
B
Step-by-step explanation:
the way i work it out is if you take the product and power it to the third you can easily find out which answer is correct. another way, if you don't have a calculator is to look at the last digit in the number in the square root sign.
For example, 3 square root 64 equals 8. you would look at the 4 and try to find 3 numbers that end in 4 OR is divisible three times by the number. 64 is exactly divisible by 4 only 3 times so you know that it can't be 8.
hope this helps!
write the equation of the line perpendicular to y= 5/2x+3 that passes through the point (-7,9). Type an answer using slope-intercept form or using the given points in point-slope form
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y = [tex]\frac{5}{2} x + 3[/tex]
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y = [tex]\frac{5}{2} x + 3[/tex]
From the given equation; slope is [tex]\frac{5}{2}[/tex]
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line = [tex]-\frac{2}{5}[/tex]
Since y= 9 and x = -7;
So;
9 = [tex]\frac{-2}{5} x (-7)[/tex] + C
9 = [tex]\frac{14}{5}[/tex] + C
C = 9 - [tex]\frac{14}{5}[/tex] = [tex]\frac{31}{5}[/tex]
Now,
y = [tex]-\frac{2}{5}[/tex]x + [tex]\frac{31}{5}[/tex]
mulitply through by 5;

3) The height of an object that is thrown straight up from a height of 6 feet
above ground is given by h(t) = -15t2 + 25t + 6, where t is the time in
seconds after the object is thrown. Find the average rate of the object from
1 to 4 seconds.
Answer:
- 44 feets
Step-by-step explanation:
Given the model:
h(t) = -15t2 + 25t + 6
Average height of object from 1 - 4 seconds
At :
t = 1
h(1) = -15(1)^2 + 25(1) + 6 = 16 feets
t = 2
h(2) = -15(2)^2 + 25(2) + 6 = - 4 feets
t = 3
h(3) = -15(3)^2 + 25(3) + 6 = - 54 feets
t = 4
h(4) = -15(4)^2 + 25(4) + 6 = -134 feets
Average height:
(16 + (-4) + (-54) + (-134)) / 4 feets = (- 176 / 4) feets
= - 44 feets

F^12 x f^12=f to the power of what
Answer:
[tex]f^{24}[/tex]
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex] , thus
[tex]f^{12}[/tex] × [tex]f^{12}[/tex] = [tex]f^{(12+12)}[/tex] = [tex]f^{24}[/tex]

how many solutions does 12x + 1 = 12x - 10
Answer:
No solutions
Step-by-step explanation:
First things first we need to get rid of the variables so we subtract -12x from one side to the other.
Now we have 1= -10
In this case, 1 is not equal to -10 so we get no solutions!
(Side note: if they were the same like 3=3 that would be all solutions.)

Simplify (1/7) to the 2 power
Answer:
ill pass
Step-by-step explanation:
The statement as (1/7) to the 2 power is equivalent to 1/49.
What is Expression?
An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Examples -
2x + 3y
3x + 5y + z
Given is a statement as (1/7) to the 2 power.
We have the given statement -
"(1/7) to the 2 power".
We can write it as -
[X] = (1/7)²
[X] = 1/7 x 1/7
[X] = 1/49
Therefore, the statement as (1/7) to the 2 power is equivalent to 1/49

M = 2/3, B = -5
M = -5, b = 3/2
M = 2, b = -6
M = -5, b= 2
Answer: m = 3/2, b = -5
Step-by-step explanation:
When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.

Answer:
B. 4.5c + 4 = 24
Step-by-step explanation:
T = cx + py is the equation you are given.
T = 24 because it is the total amount of money you can spend.
x = 4.5 because each phone case costs 4.50 dollars
p = 2 because you bought 2 pop sockets.
y = 2 because each pop socket costs 2 dollars.
There is no c because you don't know the number of phone cases you bought.
Now, we have to substitute the values into the equation:
24 = 4.5x + 2(2)
24 = 4.5x + 4
4.5x + 4 = 24 <--- This is your answer

Find (f•g)(x).
f(x) = x^2 + 4x
g(x) = 6x
Write your answer as a polynomial in simplest form.
Answer:
6x^3 + 24x^2
Step-by-step explanation:
We need to find (f * g)(x)
If we distribute the "x" here, we should get f(x) * g(x), which is what we have to solve for
f(x) * g(x) = 6x(x^2 + 4x)
= 6x^3 + 6x(4x)
= 6x^3 + 24x^2
This is the simplest expression you can get
