Explanation:

Write out an equation for the total cost. The price per pound multiplied by the number of pounds will give you the total cost.

Total cost

=

Price per pound

⋅

Number of pounds

Rearrange this algebraically to solve for  

Price per pound

. To do this, divide both sides of the equation by  

Number of pounds

to get  

Price per pound

by itself.

Total cost

Number of pounds

=

Price per pound

⋅

Number of pounds

Number of pounds

This leaves us with a new form of the equation.

Price per pound

=

Answer:50000

Step-by-step explanation:

Answer:

The investment required is: $5687

Step-by-step explanation:

Future Amount A= $7000

Rate r = 6% =0.06

Time t = 4

Compounded Weekly = n= 52

We need to find Principal Amount P

The formula used is: [tex]A=P(1+\frac{r}{n})^{n*t}[/tex]

Putting values and finding P

[tex]A=P(1+\frac{r}{n})^{n*t}\\7000=P(1+\frac{0.06}{52})^{4*52}\\7000=P(1.001)^{208}\\7000=P(1.231)\\P=\frac{7000}{1.231} \\P=5687[/tex]

Answer:

x + (x +3) + (x +7) = 37

3x = 27

x = 9

Longest side = x + 7 = 16 cm

Step-by-step explanation:

Answer:

16cm

Step-by-step explanation:

x + x + 3 + x + 7 = 37          (make all sides equal 37)

3x + 10 = 37                        (Add x's and coefficiants together)

    -10     -10                        (subtract 10 from each side)

3x = 27                               (divide 27 by 3)

x = 9                                    (answer)

x, x + 3, x + 7                      (finding longest length)

9, 9 + 3, 9 + 7                     (Substitute 9 for x)

9cm, 12cm, 16cm               (add each together)

16cm                                   (answer)

Answer:

[tex]V(x) = 66.02\ \text{in}^3 \ \vert \ _x_=_1_._9_6[/tex]

Step-by-step explanation:

The volume of a rectangular prism is found using the formula: V = lwh.

In order to write a formula in terms of the variable x, we need to write expressions for the length, width, and height of the rectangle.

We can say the length is the bottom of the base of the prism. To find this value, we can subtract x and x from 15 and divide this by 2, since there are two equal rectangles (base and lid).

We can say the width is the side of the base of the prism. To find this value, we can subtract 2x from 10.

The height of the prism can be x, which is the labeled length of the rectangle next to the base and lid.

Now we are able to write a formula for volume in terms of x.

The domain of the volume is where x > 0, 2x < 10, and 2x < 15.

This is because our expressions for length ([tex]\frac{15-2x}{2}[/tex]), width (10-2x), and height (x) cannot go below 0, because you cannot have a negative value for measurement - realistically.

Therefore, if we take into account all of these restrictions on x, the domain is where 0 < x < 5.

x cannot be > 5 since that would not satisfy 2x < 10.

The domain of V for this problem situation is D: (0, 5).

In order to find the maximum volume of the rectangular prism using our formula we derived, we can use the idea of optimization in calculus.

Start by taking the derivative of V(x).

Set the derivative equal to 0. This gives us the critical point(s) in order to determine the extreme values of the function, aka where the max and min occur.

Solve for x by using the quadratic formula.

Input this into your calculator and you should get:

We are going to use x = 1.96 since 6.37 is NOT in the domain of V(x).

Now, since this value of x is going to give the maximum volume of this rectangular prism, or cardboard box, we can plug it back into the V(x) equation for volume to determine the maximum volume of the box.

The maximum volume of the cardboard box is 66.02 in³ and the value of x that gives this is 1.96.

Answer:

To find the volume of a rectangular prism, multiply its 3 dimensions: length x width x height. The volume is expressed in cubic units.

Cube is the same

Answer:V=h×b×w

Step-by-step explanation:

You have to mulitiply height,width, and the base together to get the volume.

Answer:

Answer is B

Step-by-step explanation:

If you are unsure about where to start, you could always plot some numbers down until you see a general pattern.

But a more intuitive way is to determine what happens during each transformation.

A regular y = |x| will have its vertex at the origin, because nothing is changed for a y = |x| graph. We have a ray that is reflected at the origin about the y-axis.

Now, let's explore the different transformations for an absolute value graph by taking a y = |x + h| graph.

What happens to the graph?

Well, we have shifted the graph -h units, just like a normal trigonometric, linear, or even parabolic graph. That is, we have shifted the graph h units to its negative side (to the left).

What about the y = |x| + h graph?

Well, like a parabola, we shift it h units upwards, and if h is negative, we shift it h units downwards.

So, if you understand what each transformation does, then you would be able to identify the changes in the shape's location.

Answer:

  y > 0

Step-by-step explanation:

The range of the function ...

  y = e^(4x)

is the same as the range of any exponential function:

  y > 0

The function can take on any positive value, but will never be 0 or negative. It has a horizontal asymptote of y=0.

The range of the given function is y > 0.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given function is,

y = e⁴ˣ

This is an exponential function.

The range of any exponential function is all the real numbers which are greater than 0.

So here also, the range is all the real numbers which are greater than 0.

So range is y > 0.

Hence the correct option is B.
