What is DE ? Enter your answer as a decimal in the box. ____ units

Fantom [35]

6.3 Looking at the triangle, you can see that point D bisects line segment AB and that point E bisects line segment BC. In fact, you can easily determine that triangles ABC and DBE are similar triangles with DBE having sides that are half the length of the respective sides in ABC. And since line segment DE corresponds to line segment AC which is 12.6 units long, line segment DE is 12.6/2 = 6.3 units long.

Given the function h(w)=3w2−11w, solve for h(w)=−6.

Vesnalui [34]

Answer:

w = 2/3 AND w = 3

Step-by-step explanation:

Set 3w2-11w = -6

So 3w2-11w+6 = 0

Now factor: (3w-2)(w-3) = 0

So 3w-2 = 0 AND w-3 = 0

So w=2/3 AND w = 3

Can you explain how to do this?

ivanzaharov [21]

Hi there! The answer is x = 1

Let's solve this problem step by step!
$8(10) {}^{2x} = 800$

First divide both sides of the equation by 8.
$10 {}^{2x} = 100$

Now rewrite 100 as a power of 10.
$10 {}^{2x} = 10 {}^{2}$

Now we can use the following rule, which basically means that two different exponents of the same base must be the same
${g}^{a} = {g}^{b} \\ a = b$

We now get this.
$2x = 2$

Finally divide both sides by 2.
$x = 1$

~ Hope this helps you!
