The missing values are shown in the attached picture, and 41 degrees F = 5 degrees C.

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

Make subject C and solve:

[tex]\rm \dfrac{5}{9}(F-32) = \dfrac{5}{9}\times\dfrac{9}{5}C[/tex]

[tex]\rm \dfrac{5}{9}(F-32) = C[/tex]

Answer:

f(x) = (x + 1)^2 + 2

Step-by-step explanation:

A parabola function has different forms:

standard form: f(x) = ax + bx + c^2

vertex form:  f(x) = a (x − h)^2 + k

Our equation that includes a horizontal translation is h

- negative h shifts right

- positive h shifts left

this graph shows a shift to the left by 1 so h = 1

Our equation that includes a vertical translation is k

- negative k shifts down

- positive k shifts up

this graph shows a shift to the up by 2 so k = 2

- a represents a compression / stretch which seems not to be in this graph

combine, f(x) = (x + 1)^2 + 2

To find the probability of 2 events happening in a row, we need to multiply their probabilities.

For example, if a friend bet: "If you roll a six on a dice and filp and coin and get heads, then I'll give you 500 bucks. However, if you don't roll a six and flip and coin and get heads in a row, then you have to give me 500 bucks."

You want to know the probability of you winning this bet.

So, we need to multiply the probability of rolling a six, and the probability of flipping a coin and landing heads.

This is 1/6 * 1/2

That is 1/12

You probably should't take this bet, because you only have a 1/12 chance of winning.

Lets go back to your problem. The jar contains 16 red marbles and 28 blue marbles. The probability of picking a red marble right now is 16/28, or 4/7. Assume we picked a red marble on our first try. Now, there are only 15 red marbles. The probability of picking a red marble right now is 15/28.

Probability of picking a red marble on your first try:  4/7

Probability of picking a red marble on your second try:  15/28

Now, we need to multiply the probabilities.

If Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = PRT

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Sasha's bank account earns 4% simple interest. Therefore, if she wants it to be worth $1,000 in 5 years then the principal amount must be,

Account balance = PRT + P

$1,000 = P[(0.04×5)+1]

$1,000 = 1.2 P

P = $833.34

Hence, if Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.

Answer:

[tex]f(4)=e^{4}-3[/tex]   or   [tex]f(4)\approx51.5981500331...[/tex]

Step-by-step explanation:

The following is a general explanation of functions, what they mean, and how to evaluate them.  The simplifications and calculations at the end are based on the clarification from your comments that [tex]f(x)=e^{x}-3[/tex] .  If [tex]f(x)[/tex] is equal to something else, the simplifications/calculation will obviously be a little different, and the answer will likely be different, but the general process will be the same.

In the equation [tex]f(x)=e^{x}-3[/tex] , the left side of the equation is saying several things at once.

Names

The first character, "f", is the name of the function.

The name of a function tells you which set of directions you should look for to apply to an input.  Some functions have names that are more than one letter, and even might give a hint as to what they do, for instance I might name a certain function [tex]squareroot[/tex], and based on the name, you might guess what the equation for [tex]squareroot(x)[/tex] might look like.

Mathematicians often use "f" as a function name between different problems over and over and over again, unless they come up with a special function that is worth giving a special name to.  

Input

The rest of the characters after the name of the function, are "(x)" which is a pair of parentheses to contain the input, and the input itself.

Again, mathematicians often use "x" as a generic input over and over and over again, until we actually know which number we want to put into the function.

Output

Even though we've already discussed every character in the notation on the left, there is actually one more thing that the left side of the equation is saying:  Altogether, "f(x)" is the output of the function, when the input "x" is put in.  I feel it's worth stating, because it's often glossed over.

The equation itself

Next in the equation is the equals sign, which means that the left side of the equation, which is the output "f(x)", is equal to the stuff on the right.

The right side of the equation is the rule to follow describing what f(x) does to an input, and can help you calculate the output.

For instance, if I asked what p(4) was, it is clear that there is an input of 4, but without knowing what the function "p" does, there's no way to know what the function will give as an output when one inputs "4".  This is why the right-hand side of the equation for a function is important.

To evaluate any function, we take an input, apply the function, and simplify/calculate the output.

In this case, the question asks for [tex]f(4)[/tex], meaning that the "input" is "4".  

In this case, the question gives an explanation of what the function does through a rule given in equation form.

Given your clarification of the given function,  [tex]f(x)=e^{x}-3[/tex] , meaning a generic input (in this case "x") is put into the function "f" and the output is found by doing the arithmetic on the right side of the equation (exponentiating the number by "e", and then subtracting 4)

Notice that in the expression  [tex]f(4)[/tex], the "x"  was replaced with "4".  So, we need to substitute "4" where we see an "x" in the rule on the right hand side of the equation rule, and simplify and/or calculate (calculate, like with a calculator)

So, to evaluate the expression [tex]f(4)[/tex], simply substitute, and simplify/calculate.

Simplifying (no calculator)

To simplify without a calculator, we substitute "4".  Any time you make a substitution, use parentheses.  Then, try to simplify.

[tex]f(4)=e^{(4)}-3[/tex]

[tex]f(4)=e^{4}-3[/tex]

As it turns out, this is as much as we could simplify things here (without a calculator).  So, if an exact answer is needed, this would be it.

Calculating (with a calculator)

To calculate with a calculator, we substitute "4".  Any time you make a substitution, use parentheses.  Then, try to simplify.

[tex]f(4)=e^{(4)}-3[/tex]

[tex]f(4)=e^{4}-3[/tex]

[tex]f(4)=54.5981500331...-3[/tex]

[tex]f(4)=51.5981500331...[/tex]

So calculating with a calculator, the output of the function "f", for an input of "4", is approximately 51.598.

Answer:

Step-by-step explanation:

A function assigns the values. The value of (p·p)(x) is x⁴ + 10x³ + 30x² + 25x.

A function assigns the value of each element of one set to the other specific element of another set.

Given p(x)= x²+5x, therefore, the value of (p·p)(x) can be written as,

(p·p)(x) = p(p(x))

            = (x²+5x)²+5(x²+5x)

            = x⁴ + 25x² + 10x³ + 5x² + 25x

Answer:

y = 2x + 6

Step-by-step explanation:

We are given that a line runs through the points (-4,-2) and (-2,2).

We want to write the equation of this line in slope-intercept form.

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept, hence the name.

First, we need to find the slope of the line.

The slope can be found using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points.

Even though we have two points, let's label the values of the points to avoid confusion & mistakes.

[tex]x_1=-4\\y_1=-2\\x_2=-2\\y_2=2[/tex]

Now let's find the slope (remember: the formula has subtraction):

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{2--2}{-2--4}[/tex]

This can be simplified:

m=[tex]\frac{2+2}{-2+4}[/tex]

Add the numbers together.

m=[tex]\frac{4}{2}[/tex]

Divide.

m = 2

The slope of the line is 2.

We can substitute this into the equation for m.

Here is the equation of the line so far:

y = 2x + b

We now need to find b.

As the equation passes through both (-4, -2) and (-2, 2), we can use either one of them to help solve for b.

Taking (-4, -2) for instance:

Substitute -4 as x and -2 as y in the equation we have.

-2 = 2(-4) + b

Multiply.

-2 = -8 + b

Add 8 to both sides.

6 = b

Substitute 6 as b into the equation.

y = 2x + 6
