1.
The equation for this problem would be
y = (?)x + 190
With y being the height after a given amount of years and x being the amount of years passing. We would need to find ?, the rate of how fast the tree grows. The problem gives us y = 274 centimeters and x = 3 years
Let’s plug in and solve for ?
274 = ?(3) + 190
84 = ?3
28 = ?
The tree grew 28 cm per year
2.
Since we know the rate of change and y, let’s just plug in values
344 = 28x + 190
154 = 28x
5.5 = x
5.5 years since Renata moved.
Answer:
This is 0.25 miles per minute
The cyclist would travel 2.5 miles in 10 minutes
Step-by-step explanation:
The equation to convert miles per hour to miles per minute is to divide by 60, the number of minutes in an hour.
It should be 2,736? I think? I multiplied the fourth graders number x 4 and that’s what I got, I hope it’s correct!
Answer:
a = 5r² and b = r²s
Step-by-step explanation:
a3 - b3 = (a - b)(a + ab + b2)
Expressing 125q^6-r^6s^3 as a difference of 2 cubes
125q^6-r^6s^3
= 5³(r²)³ - (r³)²s³
= (5r²)³ - (r²s)³
Comparing with a³ - b³
a = 5r² and b = r²s
Hence the value of a is 5r² and b is r²s
