The d value is going to be -3 because you have to compute the differences of all the adjacent terms. 2-5=-3    -1-2=-3     -4-(-1)=-3   -7-(-4)=-3   The difference between all the adjacent terms is the same and equal to -3

Common difference (d) = a(2) - a(1) = 2 - 5 = -3

In short, Your Answer would be -3

Hope this helps!

Use the graph to estimate the height of a jugglers ball that has been in the air for 1.5 seconds
strojnjashka [21]

Answer:

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

Step-by-step explanation:

we are given height equation as

h=-16t^2+25t+5

where

h is the height in feet of a Juggler's ball after t seconds

now, we can plug t=1.5

h=-16(1.5)^2+25(1.5)+5

we can solve for h

h=42.5-16\cdot \:1.5^2

h=42.5-36

h=6.5

So,

The height of a jugglers ball that has been in the air for 1.5 seconds is 6.5 feet

WILL MARK BRAINLIST!!!!!
Mrrafil [7]

The correct answer is B. Two out of every five people in the shopping center are in the clothing store.

Step-by-step explanation:

To establish this answer we have to know the total number of people that were in the Shopping Center. So, we have to add people from every store.

48+96+20+64+12=240

The result of this operation is 240 people.

Later we have to divide the total number in 5 and multiply by 2.

So, the operation is

240/5 = 48

48x2=96

According to the above, the correct answer is B. Two out of every five people in the shopping center are in the clothing store.

Brut [27]

Answer:

y=-4x+9

Step-by-step explanation:

a line parallel to another line means the two lines have the same slope

so you can already cross out the second and last equation

the y-intercept is 9 so it is positive, not a negative 9
