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:
Use normalcdf ( 1.75, 1.85, 1.84, 0.07 )
Doc and Marty should have laptimes between 1.75 and 1.85 approximately 45.75% of the time.
Step-by-step explanation:
Answer:
x= 3126/125 or x=25.008 or as a mixed number form: x=25 and 1/125
Step-by-step explanation:
isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
99 marbles
Step-by-step explanation:
Let number of marbles with Alex be
Leanne has 1/2 as many marbles as Alex.
So,
Number of marbles with Leanne =
Number of marbles with Joachim =
Also, Alex has 36 more marbles than Joachim.
So,
Number of marbles with Alex = 36 + Number of marbles with Joachim
=
So,
So,
Number of marbles with Alex = 54
Number of marbles with Leanne =
Number of marbles with Joachim =
Total number of marbles =
