Which step should be completed first to solve the equation --2 = 3z + 4 ?

1 answer:

4 0

Subtract four from both sides. That'll put both numbers without a variable on one side, and the number with the variable is by itself.

The Gilbert's are designing a rectangular patio. The patio has an area of 432 square feet. The width of the patio is 3/4 it's le

ankoles [38]

Represent the unknowns.
Let x = length 
since the width is 3/4 of the length, 
Let (3/4)x = width 

Recall that the area of rectangle is just width multiplied by the length, 
A = w * l 
Substituting, 
432 = (3/4)x * x 
432 = (3/4)x^2 
432 * 4/3 = x^2 
576 = x^2 
Get the square root of both sides, 
x = 24 feet (length)

When we compute the value of a limit, all that we do is to change the value of the parameter
lim x^3 = (2)^3= 2x2x2=8
x approaches 2

Answer:

The statements that are true are:

1.575 was the coffee yield , in thousands of kilograms,before the honeybees were introduced.

1.16 represents the growth factor that reveals the rate at which the coffee yield increases.

2 is the number of times the coffee yield was compounded per year.

Step-by-step explanation:

We are given a function that models The coffee yield, in thousands of kilograms, t years after the introduction of the honeybees.

Also, the coffee yield increases according to a model where the exponential change is compounded semiannually .

The function is given by:

$f(t)=1.575(1.16)^{2t}$

Here when t=0, i.e. before the honeybees were introduced we have:

$f(0)=1.575$

Also, the rate of increase i.e. the growth rate is denoted by : 1.16

Also, 2 represents the number of times the coffee yield is compounded per year.
