Answer:

45 dollars per week

Step-by-step explanation:

To find the rate of change due y2 - y1 divided by x2 - x1

In this case,

y2 = 205

y1 = 115

x2 = 3

x1 = 1

(205-115) / (3-1) = 90 / 2 = 45

Could you help me figure out the left/right facesortop/bottom faces
jolli1 [7]

Explanation

The question requires that we figure out the sides that represent the top/bottom faces and the left/right faces.

We are given the plan of the aluminum sheet

The top, bottom, left and right faces are shown below

The dimension for the top and bottom is

1.5ft\times5ft=7.5ft^2

Since they are two

Therefore the total area for the top and bottom will be

2\times7.5ft^2=15ft^2

For the left and right faces, the dimensions are

The dimensions of the left and right faces will be

\text{1}.25ft\times5ft=6.25ft^2

Since they are two, then

The area will be

6.25ft^2\times2=12.5ft^2

Help me please!!!! I’m trying to figure this out and I really am struggling guys
damaskus [11]

Answer:

$19.68

Step-by-step explanation:

To find out how much it'll cost Melissa to buy the ribbon, we simply need to find all the side lengths (the perimeter) and then multiply then by the cost.

We already know two of the side lengths: 6 and 8. To find the third, remember that the question tells us that the triangle is a right triangle. Therefore, we can use the Pythagorean Theorem. The unknown side is the longest side. Therefore:

a^2+b^2=c^2

Substitute 6 for a and 8 for b. This gives us:

(6)^2+(8)^2=c^2

Solve for c. Square the values:

36+64=c^2

Add:

100=c^2

Take the square root of both sides:

c=10

Therefore, our unknown side is 10 feet.

Therefore, the sum of our side lengths or the perimeter is:

P=6+8+10

Add:

P=24\text{ feet}

This means that the total cost will be:

T=\frac{0.82\text{ dollars}}{\text{foot}}\cdot24\text{ feet}

Multiply. The foot/feet cancel:

T=24(0.84)\text{ dollars}

Multiply:

T=\$19.68

So, it will cost Melissa a total of $19.68 to buy the ribbon.

And we're done!

Use the table below to evaluate the derivative with respect to x of g of f of 2 times x at x = 1.
lilavasa [31]
(g o f)(2x)=g(f(2x))

take derivitive
use chain rule
remember
derivitive of g(f(x))=g'(f(x))f'(x)
so

g(f(2x))=g'(f(2x))f'(2x)(2)


at x=1
f(2x)=f(2)=1
g'(1)=1
f'(2x)=f'(2)=1

we get
(1)(1)(2)=2

it is 2
I hope yo udidn't copy the wrong value for f(x) or f'(x)

How can I obtain the graph of f(x) = -1/2(x + 2)^2 - 5 from the graph of g(x) = x^2? please show work
Anna007 [38]

Answer:

read the full answer

Step-by-step explanation:

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.

Horizontal Shift: Right  2  Units

Vertical Shift: Up  5  Units

Reflection about the x-axis: None

Reflection about the y-axis: None

Vertical Compression or Stretch: Stretched
