Answer:
As per the statement:
The path that the object takes as it falls to the ground can be modeled by
h =-16t^2 + 80t + 300
where
h is the height of the objects and
t is the time (in seconds)
At t = 0 , h = 300 ft
When the objects hit the ground, h = 0
then;
-16t^2+80t+300=0
For a quadratic equation: ax^2+bx+c=0 ......[1]
the solution for the equation is given by:
On comparing the given equation with [1] we have;
a = -16 ,b = 80 and c = 300
then;
Simplify:
= -2.5 sec and = 7.5 sec
Time can't be in negative;
therefore, the time it took the object to hit the ground is 7.5 sec
Answer:
Step-by-step explanation:
1.you have to set up a proportion(x/120 = 20%/100%
2.you have to cross multiply
3.you have to divide 100x by the number you get
4.you got your answer.
Answer:
<u>-1133</u>
Step-by-step explanation:
<u>Formula for nth term</u>
<u>Finding d</u>
- d = -45 - (-28)
- d = -45 + 28
- d = -17
<u>Solving for a₆₆</u>
- a₆₆ = -28 + 65(-17)
- a₆₆ = -28 - 1105
- a₆₆ = <u>-1133</u>
The value of 8 in 58.2 is 8 ones.
The place value of 1/10 of a value in the ones place is 8 tenth.
Therefore, from the given options, the length that has an 8 with a value of 1/10 the value of the 8 in 58.2 centimeters is 209.86cm
Answer:
8
Step-by-step explanation:
Divide 20 by 5 to get 4 then multiply that why 2.
