Kim owes her friend $245 and plans to pay $35 per week. write an equation of the function that shows the amount kim owes after x
yarga [219]
35x=245
so you would divide both sides by 35
x=7
so it would take her 7 weeks or 1 month and 3 weeks to pay her friend back

Suppose p={0,1,2,3,4,5,6,7,8,9}and V={1,3,5,7,9,11,13,15,17,19} what is PnV?
vekshin1

Answer:

P \cap V=\{1,3,5,7,9\}

Step-by-step explanation:

P \cap V means what do both lists have in common.

There is a 1,3,5,7, and 9 in both sets.

This implies P \cap V=\{1,3,5,7,9\}.

The Hyperbolic Sine (sinh(x)) and Hyperbolic Cosine (cosh(x)) functions are defined as such: sin h(x) = e^x - e^-x/2 cosh(x) = e
labwork [276]

Answer:

y-incercepts:

sinh(x):0, cosh(x)=1

Limits:

positive infinity: sinh(x): infinity, cosh(x): infinity

negative infinity: sinh(x): - infinity, cosh(x): infinity

Step-by-step explanation:

We are given that

\sinh(x)=\frac{e^{x}-e^{-x}}{2}

\cosh(x)=\frac{e^{x}+e^{-x}}{2}

To find out the y-incerpt of a function, we just need to replace x by 0. Recall that e^{0}=1. Then,

\sinh(0) = \frac{1-1}{2}=0

\cosh(0) = \frac{1+1}{2}=1

For the end behavior, recall the following:

\lim_{x\to \infty}e^{x} = \infty, \lim_{x\to \infty}e^{-x} = 0

\lim_{x\to -\infty}e^{x} = 0, \lim_{x\to -\infty}e^{-x} = \infty

Using the properties of limits, we have that

\lim_{x\to \infty} \sinh(x) =\frac{1}{2}(\lim_{x\to \infty}e^{x}-\lim_{x\to \infty}e^{-x})=(\infty -0) = \infty

\lim_{x\to \infty} \cosh(x) =\frac{1}{2}(\lim_{x\to \infty}e^{x}+\lim_{x\to \infty}e^{-x}) =(\infty -0)= \infty

\lim_{x\to -\infty} \sinh(x) =\frac{1}{2}(\lim_{x\to -\infty}e^{x}-\lim_{x\to -\infty}e^{-x}) = (0-\infty)=-\infty

\lim_{x\to -\infty} \cosh(x) =\frac{1}{2}(\lim_{x\to -\infty}e^{x}+\lim_{x\to -\infty}e^{-x}) =(0+\infty)= \infty

Yesterday, Chau had m baseball cards. Today, he gave 5 away. Using m , write an expression for the number of cards Chau has left
guapka [62]
If m = baseball cards he had yesterday, and today he got rid of 5, the expression is equal to

m - 5 = x.

As an example of what the answer is, replace m with 10.

If he had 10 baseball cards and gave away 5 today, x = 5.

The answer is m - 5 = x.
