We can solve for x or solve for y,
for x
y+6=5x
divide both sides by 5
=x
for y
y+6=5x
minus 6 from both sides
y=5x-6
A=-32 (acceleration is the constant g) integrating with respect to t
v=-32t+vi but initial velocity is equal to zero as it is just "dropped".
h=-32t^2/2+hi, since the initial height is 144 ft
h(t)=-16t^2+144
The object will be at the ground when h(t)=0
-16t^2+144
-16(t^2-9)=0
-16(t+3)(t-3)=0, but since we know t>0
t=3 seconds.
Answer:
78.5
Step-by-step explanation:
Add the two scores, and then divide this sum by 2 to obtain the average score:
Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.
