Answer: 25%
Step-by-step explanation:
You have a 1/2 chance of landing a heads or tails both times. So, you multiply 1/2 *1/2 = 1/4. 1/4 = 0.25 = 25%.

I think i am wrong but they both have acute angles
Step-by-step explanation:
sorry if this didn't help
Area of a rectangle = Lenght x width
Lenght = 80 cm
Width = 60 cm
Height = 50 cm
A = 80x 60 = 4800 cm^2
Answer:
vertex = (1, - 9 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Given
f(x) = x² - 2x - 8
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² - 2x
f(x) = x² + 2(- 1)x + 1 - 1 - 8
= (x - 1)² - 9 ← in vertex form
with vertex = (1, - 9 )
