Answer:

To find the x intercept substitute 0 for y and solve for x. To find the y intercept substitute 0 for x and solve for y.

X intercept: (-2,0)

Y intercept: (0,5/2)

im not sure if you looking for the X and Y intercept for the second equation but if you are the

X intercept: (5/2,0)

Y intercept: (0,-5)

Answer:

look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.

given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°

now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°

Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180

aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°

A sphere with a diameter of 5 feet long is being painted. how much more paint would be needed to paint a sphere that has four ti

MArishka [77]

well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).

Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.

$~\hfill \stackrel{\textit{surface area of a sphere}}{SA=4\pi r^2}\qquad \qquad r=radius~\hfill \\\\[-0.35em] ~\dotfill\\\\ \stackrel{\textit{\large difference of their areas}}{\stackrel{\textit{radius of (4)(2.5)}}{4\pi (4)(2.5)^2}~~ - ~~\stackrel{\textit{radius of 2.5}}{4\pi (2.5)^2}}\implies 100\pi -25\pi \implies 75\pi ~~ \approx ~~235.62~ft^2$

What is one tenth of 0.04

Lyrx [107]

One tenth is equal to .1 or 1/10

and .04 is nothing but 4/100

So just multiply them together:

1/10 x 4/100 = 4/1000

And since there are 3 0's we need to move the decimal spot 3 places the the left:

.004

So our final answer is $\sf{\boxed{.004}}$
