Answer:

I believe the second h=25+70t -16t

Step-by-step explanation:

because the initial height is 25 thats where you have to start and every second your adding 70 that way it's + 70t... but I don't get where the 16 comes in so I may be wrong

FIND THE RATE <br><br> PLSSSS HELPP ASSPPPP!!!!
xz_007 [3.2K]

Answer:

The rate is 13. Which also means for every tree there are 13 apples

Simple division☺ You divide the top by the bottom. 26 apples divided by two tree trees is 13 apples per tree. 39 apples divided by three trees is 13 apples per tree. See? There is a pattern. 130 apples divided by 10 trees is once again 13 apples per tree

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?
Lena [83]
To find the zeros of this equation you need to first set it equal to zero
2x2 + 16x - 9 = 0
But since you can't FOIL this equation you need to move the non-variable number over
2x2 +16x = 9
Now solve for x by pulling an x out of the equation
x(2x + 16) = 9
x = 9
2x +16 = 9
2x = -7
x = -7/2
So your zeros would be at x = 9, and -7/2

A county's population in 1991 was 147 million. In 1998 it was 153 million. Estimate the population in 2017 using the exponential
aliina [53]
Let t=number of years since 1991.
Then 
P(t)=147 e^(kt)   ... in millions
P(0)=147 e^(0)=147
P(7)=147 e^(7k)=153
e^(7k)=(153/147)
take ln both sides
ln(e^(7k))=ln(153/147)
7k=0.0400 => k=0.005715

Year 2017=>t=2017-1991=26
P(26)=147e^(26*.005715)=170.55
Answer: in 2017, the projected population is 170.55 millions.

Which correctly describes the type of symmetry of the butterfly pictured?
Alexxandr [17]

I'm not 100% sure, but I think it is A - Reflectional symmetry

I think it's Reflectional symmetry because If you look at the body of the butterfly, there is an implied vertical symmetry line right through the body.

This line makes the left image look mirrored to the image on the right.

Hope this helps :))
