Answer:. GCF of first two terms is 7r^2.
GCF for last two terms is 2
Step-by-step explanation: GCF means the largest number that the terms can be divided by evenly.
7 and 14 are both divisible by 7. The factors of those terms are (7r^2)(r +2).
r^3 means r × r × r. r^2 means r × r so r^2 is a factor of r^3
2r and 4 are both divisible by 2. The factors of those terms are (2)(r +2)

1.2,3,7.5,18.75 which formula can used to describe the sequence?
Answers
Answer:
[tex]a_n=1.2 \cdot 2.5^{n-1}[/tex]
Step-by-step explanation:
The first step is to realize that this is a geometric sequence, where each next term in the sequence is 2.5 times larger than the previous. You can confirm this by the fact that 3=1.2*2.5, 7.5=3*2.5, and 18.75=7.5*2.5. Now, you can write the formula, where n is where the number is in the sequence, and a is the number itself. Since 1.2 is the first term in the sequence and the rate of expansion is 2.5, the formula is:
[tex]a_n=1.2 \cdot 2.5^{n-1}[/tex]
Hope this helps!

An angle measures 120 degrees. Describe how to use special right triangles and the unit circle as tools to calculate the sine and cosine of this angle.
Answers
Answer:
120 degrees is the right angle and the 30 degree added which is 1/3 here we know as we can always divide a side measure by 90 then multiply by a second angle to find the hypotenuse. When we do this we are using a three way system just like a three way system appears when we use a right angle triangle and read the functions.

find the center and radius of the circle with equation (x-7)2+(y-5)2=4
Answers
Answer:
The center is (7,5) and the radius is 2
Step-by-step explanation:
We can write the equation of a circle as
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x-7)^2+(y-5)^2=2^2
The center is (7,5) and the radius is 2

Solve the equation 8.88 = 4.44(x − 7)
Answers
Answer & Step-by-step explanation:
8.88 = 4.44(x - 7)
Distribute 4.44 to (x -7).
8.88 = 4.44x - 31.08
Add 31.08 on both sides of the equation.
39.96 = 4.44x
Divide 4.44 on both sides of the equation.
9 = x
So, the value of x is equal to 9.
Answer:
x = 9
Step-by-step explanation:
Multiply the parentheses by 4.44
8.88 = 4.44(x-7)
-
Move the terms
8.88 = 4.44x - 31.08
-
Calculate
14.44x = -31.08 - 8.88
-
Divide both sides by -4.44
14.44x = 39.96
-
Solution
x = 9

Find they y-intercept
Slope
And the equation
Answers
when talking about y-intercept, you are finding where x = 0, and when finding the x-intercept, you are finding where y = 0.
Here, the y-intercept is -3 (look where x is 0)
Slope:
To find the slope, take any 2 points and use the equation:
Y2 - Y1
————— = m; m is the slope.
X2 - X1
As an example, I will take (1, -1) and (2, 1).
Y2 = 1
Y1 = -1
X2 = 2
X1 = 1
1 - (-1) 1+ 1
————— = ————— = 2/1 = 2
2 - 1 1
2 is the slope.
Or, observe how y always increases by 2 for every x (rise/run)
Equation:
Now, since we found the slope (2) and the y intercept, simply plug in the numbers into the linear equation form (y = mx + b). You should know that m means the slope and b means the y intercept. Meaning the equation is...
y = 2x - 3

We have another point (2,0) and (0,-2)
we can find the slope
m = (y2-y1)/(x2-x1)
= (-2-0)/(0-2)
= -2/-2

The slope is 1
We can write the equation in slope intercept from
y = mx+b
where m is the slope and b is the y intercept
y = 1x-2
y = x-2
