Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
, where (h,k) is the vertex
h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
Answer:
$129 000/yr
Step-by-step explanation:
Weighted average is used to answer this question.
<em>total employees are 20</em>
10 employees make 80 000
<em>total earning for 10 employees </em>= 80 000 * 10 = 800 000 (multiplying)
6 employees make 150 000
<em>total earning for 6 employees= </em>150 000 * 6 =900 000<em> (multiplying)</em>
4 employees make 220 000
<em>total earning for 4 employees </em>= 220 000 * 4 = 880 00<em>0 (multiplying)</em>
<em />
<em>To calculate weighted average all the totals are added and then divide by total number of employees.</em>
<em>weighted average =</em> (800 000 + 900 000 + 880 000)/20
<em />
<em>weighted average = </em>2580000/20
<em />
<em>Weighted average = </em>129 000
<em />
Answer:
y=4
Step-by-step explanation:
You can ignore the 3 and 6 because this has no y value change(rise over run)
This is a straight horizontal line so the equation is y=4.
Slope=0
Answer: the answer is the first one!!
Step-by-step explanation: split the shape up and multiple the numbers that came with the problem and then put all the totals together i got a total of 364!! Hope that helps!!
it is 8 or 10. multiply the 10d by 11 0r 12. 13 or 14
