The regular price of a baseball hat is 14.45$. If Carlos buys the baseball hat on sale for 20% off the regular price, how much c
otez555 [7]

Answer:

$8.44

Step-by-step explanation:

To find the 20%

x/14.45=20/100

14.45×20=289

289÷100=2.89

We then subtract 2.89 from 14.45 to get the selling price.

14.45-2.89=11.56

$11.56 is the price of the baseball hat on sale.

To get the change

20-11.56=8.44

$8.44 is the change

Inverse Function In Exercise,analytically show that the functions are inverse functions.Then use the graphing utility to show th
Anna [14]

Step-by-step explanation:

We need to show whether

f^{-1}(x) = g(x)

or

g^{-1}(x) = f(x)

so we'll do either one of them,

we'll convert f(x) to f^-1(x) and lets see if it looks like g(x).

f(x) = e^x - 1

we can also write it as:

y = e^x - 1

now all we have to do is to make x the subject of the equation.

y+1 = e^x

\ln{(y+1)} = x

x=\ln{(y+1)}

now we'll interchange the variables

y=\ln{(x+1)}

this is the inverse of f(x)

f^{-1}(x)=\ln{(x+1)}

and it does equal to g(x)

g(x)=\ln{(x+1)}

Hence, both functions are inverse of each other!

This can be shown graphically too:

we can see that both functions are reflections of each other about the line y=x.

Set up an equation to find x, Explain why you used this equation
stiv31 [10]
Answer: 180= 38+(17x+1)+(3x+1), All the angles in a triangle add up to 180 degrees, so I made all the add measures equal to 180 degrees.

Just solve that equation to find x. Then used then plug in the x value to (17x+1). After you solve that put it equal to 2y to solve for y.

So the y equation would look like: 2y=(17x+1) (but you would have solved for x and then plugged it in to the equation)

If you need help solving or have any questions let me know!

A paper clip is just over 4 cm long. How many paper clips like this can be made from a straight piece of wire 10 meters long?
bixtya [17]

Answer:

25 Paper Clips

Step-by-step explanation:

100cm is equal to 1 meter. So to find the answer you would need to take the whole of the centimeter (100) and divide that by the paper clips length (4).

100/4 = 25

So, to form a straight line 10 meters long you would need 25 paper clips each 4cm long.
