Answer:79
Step-by-step explanation:
9x8+7
=>72+7
=>79
Answer:
this is true
Step-by-step explanation:
a supplementary angle adds up to 180 degrees. two accute angles would equal to around 90 and two obtuse angles would add up to more than 180. two right angles are perpendicular and they could work but since the question asks about acute and obtuse, its true that one angle must be acute and the other must be obtuse for it to add up to 180.
Answer:
4.81 x 10^13
Step-by-step explanation:
Just count how many numbers there are and subtract it by one for the exponent, and put the decimal behind the first number.
Important: It's h = -16t^2 + 30t + 4, where " ^ " indicates exponentiation.
The units of measurement of h(t) are "feet."
Note that if time t = 0, h(0) = 4. This is the "initial value" of your function, the height off the ground of the ball at the very beginning.
As time progresses, the ball will travel skyward, slow down, momentarily stop moving, and then fall to the ground at an increasingly faster rate.
Here's the table of t and h values that you wanted:
t (sec) h(t) (feet)
0
4
0.5
15
1
18
1.5 4
2.0 0
Note that the ball must stop moving when it hits the ground. According to this table, that happens at time 2 sec. The max height reached by the ball is in the neighborhood of 18 ft, after 1 sec of upward travel.
