Answer:
B. 33.6 cm
Step-by-step explanation:
To find determine the length of an arc that subtends an angle of 2.8 radians at the centre of a circle with radius 12 cm, we will follow the steps below;
First write down the formula for calculating length of an arc
If the angle is measured in degree, then the formula for calculating the length of an arc is :
length of an arc = Ф/360 × 2πr
but if the angle is measured in radians, then the formula for calculating length of an arc will be:
length of an arc = r Ф
where r is the radius and Ф is the central angle in radians
In the case of the question given to us, the angle is given in radians, so we will use the second formula
angle Ф = 2.8
radius = 12 cm
length of an arc = r Ф
=12 × 2.8
=33.6
Length of the arc = 33.6 cm

Answer:
y intercept is -2
y = x-2
Step-by-step explanation:
The y intercept is -2 because that is where it crosses they y axis
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
= 1
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
The price of an item yesterday was
$
135
. Today, the price rose to
$
189
. Find the percentage increase.
step-by-step explanation: the increase = 204 - 120
increase = 84
percent increase = 84/120
percent increase = 70% so of course the percentage is 70% ( I hope this helps you )

1.2,3,7.5,18.75 which formula can used to describe the sequence?
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!

Ruben wants to be professional photographer and is saving up to buy a new camera priced at $2,900. After searching for the best credit
plan, he chooses an installment plan that requires a 15% down payment and monthly payments of $250 for 12 months.
Ruben will need to pay
for the down payment. He will pay
in finance charges.
He will pay in finance charges is 535.
We have given that
Down payment = 435
Finance charge = 535
Down payment = 15% of 2900 = 435
What is the finance charge?A finance charge is any fee representing the cost of credit, or the cost of borrowing. It is interest accrued on, and fees charged for, some forms of credit. It includes not only interest but other charges as well, such as financial transaction fees.
Finance charge = {(250x12) +435}- 2900
Finance charge=535
He will pay in finance charges is 535.

find the center and radius of the circle with equation (x-7)2+(y-5)2=4
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)
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

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.
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.

In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a ____ by a factor of ____.
Answer:
In the figure polygon ABCD is transformed to create polygon A’B’C’D’. This transformation is a horizontal stretch by a factor of 2.
Step-by-step explanation:
Dilation is a combination of vertical and horizontal stretch. In this case, the stretch os only horizontally applied.
We can see in the picture that the measure of figure ABCD in the x-axis is 2 units long and of Figure A'B'C'D' is 4 units long (double than ABCD). Then the stretch factor is 2.
