The answer I got is: Surface area=201.06192983. So Rounding to two decimal planes I get 201.06.
Surface area= 4(Pie)r^2
I hope this helps!

Your friend is thinking of two numbers.

frosja888 [35]

Answer:

2) 2x = y + 13

Step-by-step explanation:

We have to translate the given information into an equation. We don't know what the numbers are yet, so let the first number be represented by the variable x and the second number be represented by the variable y.

Start by breaking the sentence apart. "2 times the first number" gives us $2x$ . The "is" in the sentence means that $2x$ equals something, bringing us to $2x =$ . Finally, it says "13 more than the second number." 13 more would mean you have to add to the second number, represented by y, so this gives us $y + 13\\$ . Put it all together and it is $2x = y + 13\\$ .

H (t) = -t2 + t + 12 <br> Solve by using quadratic formula

Sedaia [141]

The quadratic formula is:

$x=\frac{-b+\sqrt{(b)^2-4(a)(c)}}{2a}$

and

$x=\frac{-b-\sqrt{(b)^2-4(a)(c)}}{2a}$

Let's identify our a, b, and c values:

a: -1

b: 1

c: 12

Plug in the values for a, b, and c into the equation. Let's do the first equation:

$x=\frac{-1+\sqrt{(1)^2-4(-1)(12)}}{2(-1)}$

Simplify everything in the radical:

$x=\frac{-1+\sqrt{49}}{-2}$

Simplify the radical:

$x=\frac{-1+7}{-2}$

Combine like terms:

$x=\frac{6}{-2}$

Simplify:

$x=-3$

This is one solution, now, let's solve for the other equation:

Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:

$x=\frac{-1-7}{-2}$

Combine like terms:

$x=\frac{-8}{-2}$

Simplify:

$x=4$

Your final answers are:

$x=-3$

$x=4$
