A diagram must be associated with the question above. Based on what I researched, this is what I got.
The blue sector of the circle is 120 degrees.
area of the blue sector = 1/3 of pi * 2^2
= 4.19cm2
I hope this answer helps.
Answer:
zeros: -11 , 7
Line of symmetry: x = -2
Step-by-step explanation:
y = 2x² + 8x - 154 = 2*(x² + 4x - 77) = 2*(x+11)(x-7)
y = 0
x = - 11 or x = 7
line of symmetry: x = 1/2 (-11 + 7) = -2
2x² + 8x - 154 = 2*(x² + 4x +4) - 162 = 2 * (x+2)² - 162
vertex (h , k): h = -2 , k = -162
Line of symmetry: x = -2
Answer:
75%
Step-by-step explanation:
First, take a look at the equation.
4, 500(1.75)^t
4500 is the y-intercept, or the INITIAL VALUE, as given in the information.
Exponential Growth is shown when the percentage is added to 1. For example, in this case, it's 1+0.75, which equals 1.75.
Therefore, annually, it increases by 75%.
10-2 = 8 therefore there are 8 frogs left
Try this explanation:
'y-interception' means x=0.
If x=0, then y=1.
answer: (0;1)
