Answer: 61.12 ft squared

Explanation: The formula for area of a circle is Pi(radius squared), the line that is eight ft is the diameter of the circle. half of it would be the radius. plug in data as usual but make sure to divide your answer by 2 because you don’t have a complete circle. You only have half. For your triangle the formula is 1/2 base • height. your height would be the 8ft line from the half circle and the base would be the bottom line of the triangle. Don’t forget to divide the base of the triangle by 2. Plug in your data. Then add your two amounts to get your answer.

Solve for x: x^2 + 28x = 60

Alisiya [41]

For this case we have a quadratic equation, $x ^ 2 + 28x-60 = 0$ , of the form $ax ^ 2 + bx + c = 0$

Where:

$a = 1\\b = 28\\c = -60$

We can solve the equation by factoring, that is, we bias two numbers that multiplied give as a result -60 and added as a result 28.

These numbers are:

$+30\ and\ -2\\+ 30-2 = + 28\\+ 30 * -2 + -60$

Then, the factorization is given by:

$(x-2) (x + 30) = 0$

The roots are:

$x_ {1} = 2\\x_ {2} = - 30$

Answer:

$x_ {1} = 2\\x_ {2} = - 30$

Find the slope of the line that passes through the pair of points.(1,7) (10,1)

VladimirAG [237]

So I believe you go
$( y_{1} - y_{2} )$ $(x_{1}- x_{2)}$

and substitute x an y like this

(1-7) (7-1)
and get a slope of -9/6

Sorry If I got it wrong,but I hope I helped
