anastassius [24]

Answer:

C

Step-by-step explanation:

A "zero" of a function is an input value that makes the function value equal zero.  On the graph these input values are -3 and 1; you can see that the function values are zero in both cases.  C is correct.

The polygons are similar, but not necessarily drawn to scale. Find the value of x.
alexandr402 [8]

If the shapes are similar, the correspondent sides are in proportion:

AB\div DE = BC \div EF

Let's plug the values and solve for x:

5x \div 5 = 4 \div x \iff \dfrac{5x}{5}=\dfrac{4}{x}\iff x = \dfrac{4}{x}

Multiply both sides by x to get

x^2=4 \iff x=\pm2

The only feasible solution, though, is x=2, because it wouldn't make sense to have negative lengths.

427 thousand in a scientific notation
ira [324]

Answer:

4.27 x 10^{5}

Step-by-step explanation:

The whole digit cannot go past 10 or be less than 1:

1 - 10 is the numbers of its max.

427,000

We would move the decimal point between 4 and 2 making:

4.2700

(Originally the decimal point moved 5 places because 427,000 is a whole number, which means the decimal point would be considered at the end, as shown below)

427,000<u><em>.</em></u>

By moving 5 places to the left this will be part of your: scientific notation as

___ x 10^{5}

(Then plug in 4.27 in front of your notation)

4.27 x 10^{5}

That is your answer!

From Kansas City to Denver is twice as far as from Kansas City to St. Louis the two distance together total 900 miles what are t
BARSIC [14]

Answer:

KC to StL = 300

KC to Den = 600

Step-by-step explanation:

KC to StL was the base distance, so we'll call that x.

KC to Denver is twice as long, so we'll call that 2x.

If we add the together is is 900 miles total.

x + 2x = 900    Combine like terms

3x = 900          Divide by 3

x = 300

If x is 300, then 2x is 600.
