Yes. You are right C=2 \pi r
Question
Solve for x if 2(5x+2)^2=48
Solution 1
2(5x + 2) ² = 48

Simplify.

2{(5x × 5x) + (2 × 2)} = 48

Simplify.

2(25x² + 4) = 48

Simplify.

50x² + 8 = 48

Subtract 8 from both sides.

50x² = 48 - 8

Simplify.

50x² = 40

Divide both sides by 50.

x² = 40/50

Simplify.

x² = 4/5

Find the square root of 4 AND 5

Question
Erin is taking part in a play at the community theater. The cast and crew ordered T-shirts for all the volunteers. The cost of a T-shirt is $8, and the total delivery charge is$45 per order. If the center has no more than $325 to buy T-shirts, how many T-shirts can they buy? NextReset Solution 1 35 T-Shirts. The charge is$45 per order for service so you take $325 -$45. that gives you 280. Then divide by 8 because it is $8 per shirt. This gives you 35 T-shirts. Question How do I solve 4n=20? Please help Solution 1 N=20/4 n=5 therefore 5 is your answer Question You roll a standard number cube Find p( number greater than 1) Solution 1 In a cube, there are six sides: just like a dice, the set of possibilities are {1, 2, 3, 4, 5, 6}. In this case, the number of sample set is 6. Hence the probability of getting a number greater than 1 is 5 that is from {1, 2, 3, 4, 5}; 5/6. The answer to this problem is 5/6.

Question Franklin deposits$3500 in an account that earns 3.5% interest compounded annually. What function equation represents the balance of the account after t years?
Solution 1
The correct answer to this question is this equation:
f(t) = 3500×(1.035)^t

The statement that says, "Franklin deposits $3500 in an account that earns 3.5% interest compounded annually" can be stated in a form of function. 3.5% --> 0.035 + 1 for 1 year$3500 --> $3500 So the equation would be f(t) =$3500 * 1.035^t
Question
Expand and simplify: (x+2)(x+2)
Solution 1
Use foil which is a lazy way to remember theh distributive property
goes like this
multiply
First terms
Outer terms
Inner terms
Last terms

so
(x+2)(x+2)
First: x times x or x²
Outer: x times 2 or 2x
Inner: 2 times x or 2x
Last: 2 times 2 or 4

x²+2x+2x+4=
x²+4x+4

Question
A ball is thrown into the air with an upward velocity of 40 ft/s. Its height h in feet after t seconds is given by the function h = −16t2+ 40t + 10. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. What is the ball’s maximum height?
Solution 1
The maximum(or minimum) of a parabolic function would be it's vertex.
To find the vertex use the formula x = -b/(2a), after finding x, plug x back into the function to find y.
The function needs to be in standard form ax^2 + bx + c, so
a = -16, b = 40
x = -40/(2*-16) = 1.25
y = -16(1.25)^2 + 40(1.25) + 10
y = -25 + 50 +10
y = 35
The maximum height is the y value of the vertex. 35 feet is the answer.
