A project on Kickstarter.com was aiming to raise $15000 for a precision coffee press. They ended up with 714 supporters, raising

Leni [432]

For this, we can set up a proportion.
Their aim was 15000, so if they raised 100% of their goal, they wouldve raised exactly 15000.
They raised 557%, so how much did they make?

Proportion:

$15000 100%
$x 557%

Our expression would be x=$15000*557% divided by 100%, which would be $83550, so... a lot of money.

(we did an “x” formation with the proportion, ie “connected” x with 100, and “connected” 15k and 557. The number connecting to x is what we divide the equation by, and the other two are multiplied and then divided by the first number connecting to x. Otherwise we couldve calculated 557% of 15000 and gotten the same result. Whichever way is easier for you :) )

What is the volume of a rectangular prism which is 4.25 inches length, 3.75 inches width and 10 ½ inches height? You must show y

pav-90 [236]

The volume would be 167.344 cubic inches because 4.25 times 3.75 times 10.5 or 10 1/2 is 167.34375 but you would round so your answer would be 167.344 cubic inches.

In a graphing program, graph the following 4 functions in the same coordinate plane.

9966 [12]

See below for the changes when the exponential function is transformed

<h3>How to determine the effect of a</h3>

The exponential functions are given as:

$y = \sqrt x$

$y = 5\sqrt x$

$y = 14\sqrt{x$

$y = -2\sqrt{x$

An exponential function of the above form is represented as:

$y = a\sqrt{x$

See attachment for the graph of the four functions.

<u>When a is large</u>

This is represented by $y = 14\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves closer to the y-axis

<u>When a is small</u>

This is represented by $y = 5\sqrt x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and it moves away from the x-axis

<u>When a is negative</u>

This is represented by $y = -2\sqrt{x$

In this case, the curve of the base form $y = \sqrt x$ is vertically stretched and is reflected across the y-axis.

At which x-value does the cosine function attain a maximum value?

Liono4ka [1.6K]

9514 1404 393

Answer:

x = 0

Step-by-step explanation:

It can help to keep a graph of the cosine function in mind. It starts off at its maximum value at x = 0.
