JulijaS [17]

Answer:

$y = -3+ rx$

Step-by-step explanation:

Given

$Base = -3C$

$Time = x$

Required

Determine the equation (y)

Let the steady rate be represented with r.

So, the equation (y) can be determined using:

$y = Base + Rate * Time$

$y = -3+ r* x$

$y = -3+ rx$

Tomtit [17]

Answer:

Step-by-step explanation:

Given that the principal p= $290

rate r= 2.2% 2.2/100 =0.022

time t= 18years

by applying the expression

$V = Pe^{rt}$

We have

$V = 290e^{0.022*18}\\\\V=290e^{0.396}\\\\V=290*1.48586931755\\\\V=$430.90$

Hence after 18years the money in the account will be $430.90

The line plot shows the growth, In Inches, of Isabella's plant over 13 days. Growth of Isabella's Plant What is the total growth

mart [117]

Line plots are used to display data elements using markers

The total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches

<h3>How to determine the total growth</h3>

From the line plot, the total growth can be represented as:

$Total = \frac 18 * 4 + \frac 28 * 2 + \frac 38 * 3 + \frac 48 * 1 + \frac 58 * 3$

Evaluate the products

$Total = \frac 48+ \frac 48 + \frac 98 + \frac 48 + \frac {15}8$

Evaluate the sum

$Total = \frac{4+4+9+4+15}8$

Evaluate the numerator

$Total = \frac{36}8$

Evaluate the quotient

$Total = 4\frac{1}2$

Hence, the total growth, in inches, of Isabella's plant is $4\frac{1}2$ inches
