1) Tan45 = 1
2) Sin70 = 0.9397
3) Cos30 = 0.8660
4) Cos20 = 0.9397
a)
h(t) , namely "h" variable is being represented in terms of "t".
h = dependent variable, depends on the value of "t", output.
t = independent variable, takes on values freely, input.
b)

c)

after 2 seconds, the ball is 11 meters high up.
Area = πr^2
area = π(7)^2
area = 49π
Answer:
The answer to your question is: (1/2, 5)
Step-by-step explanation:
Parabola f(x) = 8x² - 8x + 7
y = 8x² - 8x + 7
Vertical Parabola equation
( x - h)² = 4p (y - k) Transform the original equation to this form
8x² - 8x = y - 7
8(x² - x + ( )²) = y - 7 Complete squares
8 (x² - x + (1/2)²) = y - 7 + 2 Simplification
8 (x² - x + 1/4) = y - 5
(x - 1/2)² = 1/8 (y - 5)
Finally Vertex
(1/2 , 5)
6% of $1,600 is = 96 if you multiple it with 180 : 96 × 180 = 17,280
