Answer:
196 minutes
Step-by-step explanation:]
2x10 is 20 and if you divide 5/10 its 2 so the 4 in 4/5 is the total of 8 because 10 would mean 5/5 and 20+8=28 so 28x7 is 196
Answer:
The correct option is;
D. -8·t² + 18·t + 6 = 10
Step-by-step explanation:
The given equation of the height toy cannon launched on top of a platform is given as follows;
h(t) = -8·t² + 18·t + 6...(1)
Where "h" represents the height in meters, at time "t" seconds after the ball is launched
When the height is 10 meters, we can write as follows;
The height of the ball, h(t) = 10
Therefore, by substituting the value of h(t) in equation (1), h(t) = -8·t² + 18·t + 6, when h(t) = 10 we get;
-8·t² + 18·t + 6 = 10.
Answer:
x = ±4i or x = ±√-16
Step-by-step explanation:
x² - 5x + 19 = 5x + 3
x² + 16 = 0
x² = -16
x = ±√-16 (a negative square root is an imaginary number)
4x+5 feet
A square has 4 sides, and all of them are the same size. Because of this, you divide the whole expression by 4, and you’re left with 4x+5.
16x/4=4x
20/4=5
