For question 4, it would be a^2+b^2=c^2. So you would set up the equation as a^2+14^2=18^2. the third side would equal approximately 23cm.

The table shows the relationship between the height of a tomato plant and the number of days since it has been planted
Vika [28.1K]

Answer:

The y-intercept represent Height

Step-by-step explanation:

In a graph the independent variable is plotted on the  X axis and attain only certain discrete values. The Dependent variable is plotted against the Y axis and may be discrete or continuous.

Here in the given question

Days:    2,5,8,12,18,22,25,30,32,35

Height: 3,4,6,9,13,15,16,20,21,24

The height is a dependant variable because we are trying to determine a relationship between the Days and the height. In particular, we are trying to see how the height depends upon what day it is or what is the height of the pant on the particular day.

The day can be only discrete values where height can be both discrete and continuous.

So height can be represented along Y axis

Andrew bought a house worth 200,000 dollars the house value appreciates 1% per year which of the following would help you find t
Aleks [24]

Answer: Option 1:

y=200,000(1.01)exponent 20

Step-by-step explanation:

The house value appreciates 1% per year. It means that the rate at which it is appreciating is exponential. We would apply the formula for exponential growth which is expressed as

y = b(1 + r)^ t

Where

y represents the value of the house after t years.

t represents the number of years.

b represents the initial value of the house.

r represents rate of growth.

From the information given,

b = 200,000 dollars

r = 1% = 1/100 = 0.01

t = 20 years

Therefore,

y = 200000(1 + 0.01)^20

y = 200000(1.01)^20
