Where h=-6 and k=-5whereh k vertex of a parabola
Answer: The dimensions are 8 and 3
Step-by-step explanation:
So 8*3=24 which corresponds with the formula for area l*w= Area
And perimeter means we add up all 4 sides so
8+8+3+3= 22
So the dimensions are 8 and 3
The solutions of the quadratic equation 0 = -3x² - 4x + 5 are
and
Step-by-step explanation:
The quadratic formula of the quadratic equation ax² + bx + c = 0, is
To find the solution of the quadratic equation by using quadratic formula
- Find the values of a, b, and c from the quadratic equation
- Substitute these values in the quadratic formula
- Calculate the values of x
∵ -3x² - 4x + 5 = 0
∴ a = -3 , b = -4 and c = 5
- Substitute these values in the quadratic formula
∵
∴
∴
- Simplify by dividing up and down by -2

Answer:
78.5
Step-by-step explanation:
The formula for area of a circle is pir^2
So we have 5 for r, so r^2 would be 25.
Using 3.14 for pi, we get the answer is 78.5
