Answer:

  [tex]y=\sqrt[3]{x+3}+3[/tex]

Step-by-step explanation:

The S-shaped curve is that of the cube root function (choices C or D). The parent function has its critical point at the origin. Here, that has been moved 3 units left and 3 units up.

Replacing x with x-a will move a function's graph to the right by "a" units. Here, we have a=-3, so we expect to see ∛(x-(-3)) = ∛(x+3). The graph of that is moved up 3 units by adding 3 to the function value. This gives ...

  y = ∛(x+3) +3 . . . . . matches choice D

Solving e²ˣ + 3eˣ- 18 = 0 involves substituting y = ex to transform it into a quadratic equation. Solving this quadratic equation yields a valid solution, y = 3, leading to x = ln(3). Therefore, the solution is x = ln(3).

To solve the equation e²ˣ + 3eˣ- 18, we perform a substitution to convert it into a quadratic form.

Let y =eˣ. Then the equation becomes:

This gives us two solutions for y:

Since y = eˣ, and eˣ must be positive:

Finally, solve for x:

Therefore, the solution to the equation e²ˣ + 3eˣ- 18 = 0  is x = ln(3).

For 12 number of aerobics classes, cost for members and nonmembers is same

Solution:

Let "x" be the number of aerobic classes

At a local fitness​ center, members pay a $12 membership fee and ​$3 for each aerobics class

Therefore,

Members pay = 12 + 3(number of classes)

Members pay = 12 + 3x ------- eqn 1

Nonmembers pay ​$4 for each aerobics class

Nonmembers pay = 4x ------- eqn 2

For cost for members and nonmembers be the​ same, eqn 1 must be equal to eqn 2,

12 + 3x = 4x

4x - 3x = 12

x = 12

Elmer's bank contained coins totaling $1.37, calculated by summing the value of each type of coin separately.

To find the total value of the coins in Elmer's bank, we need to calculate the value of each type of coin separately and then sum them up. The value of coins is counted based on their denomination, with pennies being worth 1 cent, nickels 5 cents, dimes 10 cents, and quarters 25 cents.

Adding these amounts gives us a total value of 17 + 20 + 50 + 50 = 137 cents. Therefore, the value of the coins in Elmer's bank is $1.37.

The value of the coins in Elmer's bank is $2.17.

17 pennies = $0.17

4 nickels = $0.20

5 dimes = $0.50

2 quarters = $0.50

Adding these amounts together: $0.17 + $0.20 + $0.50 + $0.50 = $2.17.

since since the scale factor is 3 angle ab abyou multiply 6 * 3 to get 18

The length of the Side EF is 18.

A scale factor is defined as the ratio between the scale of a given original object and a new object.

Given that  corresponding sides are AB and EF, and EF is a side of the larger (second) triangle.

scale factor 3 means each length of the second is 3 times as long as the first.

Therefore, the length of the side EF when the length of side AB is 6 units is,

EF = 3 x AB

     = 3 x 6 units

     = 18 units.

Therefore, Side EF is 18.

Answer:

30240

Step-by-step explanation:

There are two primary ways to approach this problem - the logical and the mathematical.

The logical way is very simple:

Since you know that there are 5 digits and each must be different, start with the first digit and work your way up.

The first digit can be any of 10 digits (0–9).

However, the second digit can be any of only 9 digits as 1 digit has already been used and cannot be repeated.

Similarly, applying the same logic, there are only 8 options for the third digit, 7 for the fourth digit, and 6 for the fifth and final digit.

Now, multiply all these numbers together to get the total number of configurations like so:

10⋅9⋅8⋅7⋅6=30240

The more mathematically inclined way requires the use of a special formula. Since in this particular scenario, the order of the numbers matter, we can use the Permutation Formula:

P(n,r)=n!(n−r)!

where n is the number of numbers in the set and r

is the subset.

Since there are 10 digits to choose from, we can assume that n=10

.

Similarly, since there are 5 numbers that need to be chosen out of the ten, we can assume that r=5

.

Now, plug these values into the formula and solve:

=10!(10−5)!

=10!5!

=10⋅9⋅8⋅7⋅6

The sphere has a diameter of 32 in.

The radius’s length is one-half the length of the diameter.

The volume of the sphere is StartFraction 16,384 Over 3 EndFraction pi inches cubed.

Step-by-step explanation:

      This is false because a radius is half of a diameter. Half of      the given diameter of 8 in is 4 in whereas the radius in the question is 16 in.

        This is false because the volume of the sphere is 4πr³/3 = (16,384/3) π cubic inches.

This is True because a radius is half of a diameter. Half of the given diameter of 32 in is 16 in and  the radius in the question is also 16 in.

This is True because a radius is half of a diameter

This is True because the volume of the sphere is 4πr³/3 = (16,384/3) π cubic inches.

It is the radius’s length that is one-half the length of the diameter

7.50*35=262.50

Step-by-step explanation:

The correct equation of the new line parallel to y = 3x + 2 and passing through (1, 6) is y = 3x + 3.

To find the equation of the line that is parallel to the given line y = 3x + 2 and passes through the point (1, 6), we first need to acknowledge that parallel lines have the same slope.

Therefore, the slope of the new line will also be 3. We can use the point-slope form of the equation y - y1 = m(x - x1) to find the equation. Substituting the given point into the equation, we get y - 6 = 3(x - 1).

Simplifying the equation, we find y = 3x + 3. So, the equation of the line that is parallel to the original line and passes through the given point is y = 3x + 3.

Answer:

Step-by-step explanation:

y = mx + b

slope(m) = 1/9

y int (b) = 8.....or (0,8)

y = 1/9x + 8.....this is ur equation

ur x intercept is : (can be found by subbing in 0 for y

0 = 1/9x + 8

-1/9x = 8

x = 8 * -9

x = - 72....or (-72,0)

The equation of line is y = ( 1/9 )x + 8

What is an Equation of a line?

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is given by

The slope of the line m = 1/9

So , Slope m = 1/9

The point on the line is given by P = P ( 0 , 8 )

Now , the equation of line is y - y₁ = m ( x - x₁ )

Substituting the values in the equation , we get

y - 8 = ( 1/9 ) ( x - 0 )

y - 8 = ( 1/9 ) x

On simplifying the equation , we get

Adding 8 on both sides of the equation , we get

y = ( 1/9 )x + 8

Therefore , the value of A is y = ( 1/9 )x + 8

Hence , The equation of line is y = ( 1/9 )x + 8

Final answer:

Nancy bought 177 long sleeve shirts and 354 short sleeve shirts for her business by solving a system of linear equations based on the provided constraints that she bought a total of 531 shirts and twice as many short sleeve shirts as long sleeve shirts.

Explanation:

The student's question involves solving a system of linear equations to find out how many of each type of shirt Nancy bought for her business. Following the given relationships between long sleeve shirts (x) and short sleeve shirts (y), we understand that Nancy bought a total of 531 shirts and that she bought twice as many short sleeve shirts as long sleeve shirts. The two equations that can represent this scenario are:

Equation 1: x + y = 531

Equation 2: y = 2x

To solve this system, we substitute Equation 2 into Equation 1 to get:

x + 2x = 531

Which simplifies to:

3x = 531

Dividing both sides by 3, we find that:

x = 531 / 3 = 177

Using the value of x to find y from Equation 2, we get:

y = 2 * 177 = 35

Therefore, Nancy bought 177 long sleeve shirts and 354 short sleeve shirts.
