B(t)=50×e^2.5t

e^2.5t = 20
t= ln(20) / 2.5 
set B(t)=1000 and solve for t via 1000=50e2.5t
20=e2.5t
ln(20)=2.5t
t=ln(20) / 2.5

Which function has the given properties below? The domain is the set of all real numbers. One x-intercept is (2 pi, 0). The ampl
Tomtit [17]

The functions y = -4sin (x) and y = 4sin (x) has the given properties.Functions help to define the relationship between the independent and the dependent variable.

<h3>What is function?</h3>

A expressions defining a connection between the independent variable and dependent variable is known as the functions.

A feature that:

The domain is defined as the set of all real numbers.

a single x-intercept

The amplitude is four.

The y-intercept is defined as (0,0)

Because the specified function goes through the functions having "cosine," the functions containing "cosine" can be omitted from the selections (0,0). As a result, we have two options:

Hence  y = -4sin (x) and y = 4sin (x) has the given properties.

The area of rectangular is 46 square inches.if the length is 4 times the width . Then find the dimensions of the rectangular
dimulka [17.4K]

Answer:

the rectangle's width is approximately 3.39 inches

and the length is approximately 13.56 inches.

Step-by-step explanation:

Recall that the area of a rectangle is Length times Width

If we name the length "L" and the width "W", we have:

L * W = 46

Also: "the length is 4 times the width" can be written in math form as:

L = 4 * W

and now we can replace the length L by 4 * W in the formula for the area:

L\,*\,W = 46\\(4\,W) \,W = 46\\4\,W^2=46\\W^2=\frac{46}{4} =11.5\\W=\sqrt{11.5} \\W\approx 3.39

and now we find the value of L:

L=4\.(3.39) = 13.56

Therefore, the rectangle's width is approximately 3.39 inches

and the length is approximately 13.56 inches.

How many years will it take for 20$ to grow to 100 if the simple interest rate is 4% annually
cestrela7 [59]

The formula for simple interest is:

Total = Principal(1+ Rate x time)


You are given:

Total = $100

Principal = $20

Rate = 4%


You are asked to find the time.

Replace everything known in the formula:


100 = 20(1 +0.04 x Time)

Now solve for Time:

Divide each side by 20:

5 = 1 + 0.04 x Time

Subtract 1 from each side:

4 = 0.04 x time

Divide each side by 0.04:

Time = 4 / 0.04

Time = 100 years.
