Answer:
x=25
Step-by-step explanation:
125+30= 155
180-155=25
180 is the overall total of the line so the angels will add up to 180
A. When the key reaches the ground, h = 0.
0 = -16t^2 + 64
16t^2 = 64
t^2 = 4
t = 2 seconds.
B. The reasonable domain of the function is [0, 2], since the function does not hold when the key reaches the ground. The range of the function is [0, 64] which corresponds to the domain.
Answer:
-2
Step-by-step explanation:
Put the given values of x and y in the equation, and solve for "a".
-40 = a(1 +3)(1 -2)(1 -6) = 20a
-40/20 = a = -2
The value of "a" is -2.
Answer:
T=48
Step-by-step explanation:
Now since I don’t know the height at the present moment, I’ll just make this ratio (of the tree) be represented as x/36. Which is saying that for every ‘x’ amount of feet, there will be 36 feet of shadow.
so we have 4/3=x/36. If I cross multiply 36 and 4, then divide the product by 3, then ‘x’ will be 48.
Answer:
A and C
Step-by-step explanation:
2(6x-4+5x)
12x-8+10x
22x-8 / 2 = 11x-4
