- πr² = 25
<u>Area of the larger circle:</u>
Answer:
t1= 5.35
Step-by-step explanation:
Projectile height formula should be
h= -1/2gt^2+v0t+h0
where
h= height, this question asking time when "ball hit the ground" so height is 0
t= time, we look for this variable
v0= initial velocity= 85 feet/s
h0= initial height = 6 feet
g= gravity, assumed 32 feet/s^2
The calculation will be:
h= -1/2gt^2+v0t+h0
0= - 32 t^2+85t+6
0= -16t^2+85t+6
16t^2 - 85t -6 =0
x=
t=
t=
t=
t=
t1=
t1= 5.35
t2=
t2= -0.035
The answer can't be minus, so its t1
Answer:
at matilda's new job, she will make a rounded salary of $69,000 per year.
Step-by-step explanation:
when solving a problem like this, you have to take her current salary ($64,000 per year) and multiply it to the salary increase percentage by first turning the percentage into a decimal. to turn the percentage into a decimal, you imagine a tiny dot to the right of the 8 like this:
8.
and then you have to move that little dot to the left two times recreating it into .08. you multiply .08 (the salary increase percentage) by her current salary ($64,000) and then also add that number to matilda's current salary to come up with the answer you can round. I'll give you an example of my proscess just so I can give a clear visual of my explanation.
step one:
$64,000
x .08
-------------
5,120
step 2:
$64,000
+$5,120
-------------
$69,120
step 3:
$69,120 is rounded up to the nearest thousands is approximately $69,000
answer: $69,000
