Answer:
Step-by-step explanation:
the shape can be divided into two semi-circles of radius 5 cm and (11x10) cm rectangle
so,
area = (2 x 0.5x pi x 5x 5) + (11x10) = 188.5 cm sq
What is the solution (not answer) to (not too) x^2 - 3x + 5 = 0?
This is a quadratic equation. Two possible approches to solving it are
1) quadratic formula, and
2) completing the square.
Let's use the quadratic formula:
a=1, b= -3, c = 5
Then
-(-3) plus or minus sqrt( [-3]^2 - 4(1)(5) )
x = --------------------------------------------------------
2
3 plus or minus sqrt(9-20) 3 plus or minus i*sqrt(11)
= ------------------------------------- = ------------------------------------

Please note: These are complex roots, due to the " i ".
10.65/8.20= 1.30
1.30-1 ( for the 100% that was there)
.30 x100 (to get in percent)= 30 percent increase
Answer:
see below
Step-by-step explanation:
Since the initial value is 5 and it increases by 3 every time x goes up the equation is y = 5 * 3^x.
