How long does it take for an investment to double its value if the interest is 7.25%
compounded continuously?

Answer:

D. 4

Step-by-step explanation:

Use rise over run, (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(20 - 12) / (4 - 2)

8 / 2

= 4

So, the slope is 4.

Answer:

In the graph, the y-intercept is -2. The equation of the line is [tex] y = x - 2 [/tex]

Step-by-step explanation:

The equation of the line can be written in the slope-intercept form, y = mx + b.

First we need to find:

The slope = m

the y-intercept = b

Using two points on the line, (0, -2) and (2, 0) the slope can be calculated as follows:

[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 -(-2)}{2 - 0} = \frac{2}{2} = 1 [/tex]

The y-intercept is simply the point at which the line intercepts the y-axis. It is the value of y when x = 0.

Therefore, the y-intercept, b, = -2.

Substitute m = 1 and b = -2 into [tex] y = mx + b [/tex].

Thus, the equation if the line would be:

[tex] y = (1)(x) + (-2) [/tex]

[tex] y = x - 2 [/tex]

Answer:

[tex]f(5)=3.5[/tex]

Step-by-step explanation:

[tex]f(x)=\frac{3}{2}x-4\\f(5)=\frac{3}{2}(5)-4\\f(5)=7.5-4\\f(5)=3.5[/tex]

Hope this helped!! Have an amazing day :D

The required value of the linear function at x = 5 is 7 / 2.

Given that, a linear function f(x) = 3/2x-4 we have to determine the value of the function at x = 5 that is f(5).

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Liner function,
f(x) = 3/2x-4
Put x = 5 in above function,
f(5) = 3 * 5 / 2 - 4
f(5) = 15 / 2 - 4
f(5) = 15 - 8 / 2
f(5) = 7 / 2

Thus, the required value of the linear function at x = 5 is 7 / 2.

Answer:

I do not agree because if there is an equation like 7+8 the answers would not be equal. They can only be equal if you add 8 to each side of the same number. For example, 7+7 with 8 added on both sides would be equal. But Maggie says that it can be equal for any equation. Therefore, Maggie is wrong.

d i have this ? to so thats how ik

Step-by-step explanation:

so the problem is y-2=3(x-1)

in this problem you have to rmb the forumla

y-y1=m(x-x1)

to find the points

so in the equation -1 would be x1 thats one point but you turn the -1 into a postive one dont know why thats just what my tutor said

so know you know one of the points (1,

to find the other you have to seaarch for y1 which from using the forumla you would know is -2 but you have to turn it in to a postive

This actually the answer for a deff problem but if you got the problem thats asking for which quarterpoints then this is it

so the points are (1 , 2)

The equation of a line in slope-intercept form is expressed as y = mx + b

m is the slope of the line

b is the y-intercept

Given the equation y − 2 = 3(x − 1), express in the form y = mx + b

y - 2 = 3x - 3

y = 3x - 3 + 2

y = 3x - 1

Speaking from experience, when you work with rational (fraction) polynomials on paper, it often tends to take up a bit of space and get messy. Therefore, I'd suggest you tried solving one equation at a time if you have the same issue.

Also, sometimes you may come across values that you don't want to type again in your calculator (like non-recurring decimals). For these, use the store function on your calculator to get maximum accuracy. With TI-84 and 83s, you can save values as letters (X, Y, etc.). Hence, you can just write out your equation using these, and hence significantly reduce the risk of typing the number wrong, while saving yourself some time.

Mega Melt's food truck can make 84 grilled sandwiches in 3 hours today.

Given that, yesterday, Mega Melt's food truck made 56 grilled cheese sandwiches in 2 hours.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Here,

The number of sandwiches grilled in 1 hour = Total number of sandwiches grilled/Number of hours

= 56/2

= 28

Number of sandwiches grilled in 3 hour = 28×3

= 84

Therefore, Mega Melt's food truck can make 84 grilled sandwiches in 3 hours today.

Answer:

The volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

Step-by-step explanation:

Given that,

The volume of a right circular cone is 300 cubic inches

We need to find the volume of a  right cylinder that  has the same base and height as the cone.

Volume of a cone is given by :

[tex]V=\dfrac{1}{3}\pi r^2h[/tex]

And volume of a cylinder is given by :

[tex]V'=\pi r'^2 h'[/tex]

If the base and height of cone and cylinder are same, r=r' and h=h'

[tex]\dfrac{V}{V'}=\dfrac{1/3\pi r^2 h}{\pi r'^2h'}\\\\=\dfrac{1/3\pi r^2 h}{\pi r^2h}\\\\\dfrac{V}{V'}=\dfrac{1}{3}\\\\V'=3V[/tex]

So, the volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.
