Answer:

V = 5x² - 100x + 500

The answer is v=5x^2-100x+500. First, since we are finding the volume of a square you already know that the equation for a square is volume= length*width*height. Because 5 inches was cut off from each side, that means that each side is now 10 inches shorter than it originally was. So, then you substitute the values into the formula.  So the length is x-10 and the width is also x-10 and the height is 5in. Then you write the formula like this (x-10)(x-10)5. Second, you substitute the values into the formula. Since there are 2 x's that would make x^2 and add that to 5 that would make 5x^2. Then you multiply -10*10=-100. Finally, you multiply -10*-10-5=500. Then you add them all together to get 5x^2-100x+500

If a 42.9 ft tall flagpole casts a 253.1 ft long shadow then how long is the shadow that a 6.2 ft tall woman casts?
blsea [12.9K]
We will have to use proportions:
\frac{42.9}{253.1}  =  \frac{6.2}{x}
Cross multiplying we get
42.9x = 6.2 \times 253.1
Now divide:
x =  \frac{6.2 \times 253.1}{42.9}
Solve to tenths place we get
x = 36.6
The woman casts a 36.6 ft long shadow.

Which of the following is not a correct name for the line shown?
Talja [164]

Answer:

D

Step-by-step explanation:

The line can be named with small latin letters or with two large latin letters which represent two points lying on the line.

Consider all options:

A. Points V and X lie on the line, so you can name the line as VX (true option)

B. Points W and X lie on the line, so you can name the line as WX (true option)

C. p represents the line (small letter given on the diagram) - (true option)

D. You cannot name the line using point V and line p, so this option is false

Solve the following function for y when x=5 round to the nearest tenth
Wittaler [7]

In the given question , we have a function given , which is

y= 13(0.5^x)

And we need to find the value of y when x=5.

So we substitute 5 for x and solve for y, that is

y=13(0.5^5) = 0.40625

And on rounding to the nearest tenths, we will get

y=0.4

So when x=5, y=0.4
