Step-by-step explanation:
Rosa throws a ball. The equation d = −t^2 + 4t + 5 represents the path taken by Rosa's ball where d is the height of the ball (in feet) after t seconds. How long was the ball in the air?
A. 1 second
B. 4 seconds
C. 5 seconds
D. 9 seconds
Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.
There is a proportional relationship between the cost of the movie subscription and the number of months a person has had the service. For 12 months the cost is $95.88. The point (6, 47.94) is on the line.
Label the x-axis and y-axis appropriately.
Write an equation that represents the proportional relationship between months and cost. Use the variable “m” for months and “c” for cost.
What does the “6” mean in the point (6, 47.94) in terms of the situation?
What does the “47.94” mean in the point (6, 47.94) in terms of the situation?
Answer:
c=7.99m
6 is the number of months
47.94 is the cost per 6 months
Step-by-step explanation:
95.88/12=7.99

Hello!
A function will be increasing if the y values are increasing (since this is a function, this will pass the vertical line test, meaning that it is increasing if the y values are increasing).
On interval 1, the function is not increasing since the y value stays constant.
On interval 2, the function is increasing because the y values are increasing.
On interval 3, the function decreases because the y values are decreasing.
On interval 4, the function increases again.
On interval 5, the function stays the same because of its constant y value.
To reiterate, on intervals 2 and 4, the function is increasing.
Hope this helps!

The complement of the angle is 1/2 of the measure of the angle. Find the measure of the angle.
Group of answer choices
1.180°
2.90°
3.60°
4.30°
Answer:
choice 2) x = 60°
Step-by-step explanation:
the complement of an angle is an angle that when added to the original angle = 90°
so:
x + 0.5x = 90°
1.5x = 90°
x = 90/1.5 = 60°

Consider the data below.
2, 2, 2, 3, 5, 6, 8, 30
The mean decreases by ? when the outlier is removed.
Answer:
It is decreased by 3.25
Step-by-step explanation:
When you add all 8 numbers you'll get 58 then you divide them by 8 you will get 7.25 which is the mean. To find out what is the decrease we need to take out the 30 and add all the other numbers and we get 28. After that you divide 28 by 7 and you get 4. Subtract 4 from 7.25 and you get 3.25.
2+2+2+3+5+6+8+30=58
58/8=7.25
2+2+2+3+5+6+8=28
28/7 = 4
7.25-4=3.25
How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? Or how are they different. Explain one of the two or how their similar and different. Thanks :)
I give brainliest to whichever makes the most sense
Answer:
They are different because in the mantle, the magma is heated, it becomes less dense and rises. It give off it's thermal energy and cools down, becoming more dense and descend to be heated again.
In the ocean, the tropics warm the water and it travels to the poles to cool down, then returns to the tropics to heat up again.
