Answer:
He is not correct
Step-by-step explanation:
10 x 50 = 500
500 + 10 = 510
510 represents plant 1 height after 50 weeks
8 x 50 = 400
400 + 18 = 418
418 represents plant 2 after 50 weeks
they're not the same height
Answer:
M(h) = 73.18025h
Step-by-step explanation:
The composite function is ...
M(B(L(h))) = M(B(28.75h)) = M(1.78(28.75h)) = M(51.175h)
= 1.43(51.175h) = 73.18025h
The composite function is ...
M(h) = M(B(L(h))) = 73.18025h
Answer:
-4
Step-by-step explanation:
Indeed, the y-value changes by 4 when the x-value changes by 1. However, the y-values <em>decrease</em> when the x-values increase. That means the slope is <em>negative</em> 4.
___
Any line that goes down to the right has a negative slope. Its slope is positive if it goes up to the right.
Answer:
y²z²-x²
3*3*4*4-2*2
3*16-4
48-4
44
Step-by-step explanation:
* means multiply
Answer:
Your answer is 5 weeks!!
Step-by-step explanation:
How I got my answer; First I checked if 2 weeks would work by doing 2( the umber of weeks) *3( the number of inches it grows per week) which is 6, I then added 6 to 3 inches (which is the original height of the plant) and I got 9.
I did the same process with the 2nd plant;
2(the number of weeks) *2( the number of inches the plant grows per week) which is 4. I then added 4 and 8( the original height) and I got 12.
(THE EXPLANATION FOR HOW I GOT 5 WEEKS STARTS HERE)
So I continued to do this process with 2,3,4 and 5, and finally I got my answer at 5weeks.
5(the number of weeks) * 3(the rate the plant grows per week) which is 15inches. I then added 15 to the original height which is 3inches, 15 +3 is 18 inches so that is my answer for how tall the 1st plant would get in 5 weeks .
Now the 2nd plant;
5(the number of weeks) * 2(the rate the plant grows per week) which is 10inches. Now I'm going to add the original height (8) with the rate the 2nd plant would grow after 5 weeks (10), 10+8 is 18 so the plant would grow 18inches after 5 weeks which is the same height as the first plant.
Hope this makes sense :)
