What is the product of (5× + 1)(5x - 1)?

padilas [110]

we are given

$(5x + 1)(5x - 1)$

we can distribute it

$5x*5x-1*5x+1*5x-1*1$

$25x^2-5x+5x-1$

now, we can simplify it

$25x^2-1$ ...............Answer

Determine the volume of the figure. Use 3.14 for π. Round your answer to the nearest tenth. Show all of your work.

Ostrovityanka [42]

Answer:

1985 cubic units (written as un. with the cubed exponent)

Step-by-step explanation:

First, you find the volume of the cylinder

Here's the formula:

$V=\pi r^{2}h\\V=volume\\r=radius\\h=height$

Now, you plug in and solve.

$V=(3.14)(7.2^{2})(7.4)\\V=(3.14)(51.84)(7.4)\\V=(162.7776)(7.4)\\V=1204.55424\\rounded:\\V=1204.6$

Then, you find the volume of the dome.

Here's the formula:

$volume/of/a/sphere=\frac{4}{3}\pi r^{3}\\volume/of/a/dome:\\V=\frac{2}{3}\pi r^{3} \\V=volume\\r=radius$

Now, you just plug in and solve.

$V=(\frac{2}{3})(\pi)(r^{3})\\V=(\frac{2}{3})(3.14)(7.2^{3})\\V=(\frac{2}{3})(3.14)(373.248)\\V=(2.093)(373.248)\\V=781.208064\\rounded:\\V=781.2$

Finally, you add them together, and there's your answer!

$1204.6+781.2=1985.8$

Hope this helped!

Find the distance between (4,2) and (-4,-4)

VikaD [51]

Use the distance formula, and plug in values.
$d = \sqrt{(x_{2}-x_{1} )^{2}+(y_{2}-y_{1} )^{2}}$
<u /> $d = \sqrt{( -4-4 )^{2}+( -4-2 )^{2}}$
$d = \sqrt{( -8 )^{2}+( -6 )^{2}}$
$d = \sqrt{64+36}$
$d= \sqrt{100}$

Therefore, the distance is equal to "10".
