Major help I would highly appreciate it:(
Elena L [17]

Answer:

  9

Step-by-step explanation:

The function's y-intercept is the value for x=0.

  h(0) = 0.5(0 +4)² +1

  = 0.5(16) +1

  = 8 +1

  h(0) = 9

The function's y-intercept is 9.

The ages (in years) of the 6 employees at a particular computer store are 44, 46, 40, 34, 29, 41
son4ous [18]
step 1
<span>compute the average: add the values and divide by 6
Average =(44+ 46+40+34+29+41)/6=39

step 2
</span><span>Compute the deviations from the average
dev: (44-39)=5,
</span>dev: (46-39)=7
dev: (40-39)=1
dev: (34-39)=-5
dev: (29-39)=-10
dev: (41-39)=2

step 3
<span>Square the deviations and add
sum (dev^2): 5^2+7^2+1</span>^2+-5^2+-10^2+2^2
sum (dev^2): 25+49+1+25+100+4-----> 204

step 4
<span>Divide step #3 by the sample size=6
(typically you divide by sample size-1 to get the sample standard deviation,
 but you are assuming the 6 values are the population,
so
no need to subtract 1, from the sample size.
This result is the variance
Variance =204/6=34

step 5
</span><span>Standard deviation = sqrt(variance)
standard deviation= </span>√<span>(34)------> 5.83

the answer is
5.83</span>

8. What happens to acceleration when the velocity changes by the same<br> amount over time?
Nookie1986 [14]

Answer:

The acceleration will also be uniform when velocity changes by the same amount over time.

Step-by-step explanation:

Acceleration is defined as a rate of change of velocity per unit time.

Unit of the acceleration is m/s^{2}

So,here when the velocity changes by the same amount over time, the change here will be <u>UNIFORM</u>.

Hence, the acceleration will also be uniform when velocity changes by the same amount over time.

a source of laser light sends rays ab and ac toward two opposite walls of a hall. the light rays strike the walls at points b an
marissa [1.9K]
Let  AM be the distance between point A and the right wall and AN be the distance between A and the left wall.
Δ AMB is an isosceles right triangle and  Δ ANC is half of an equilateral triangle.
Length of AM = 30 m. Length of AN = 1/2 · 80 = 40 m.
The distance between the walls is:
30 m + 40 m = 70 m.
