Answer:

B.) why Factor p+ 12r - 6, I did not do that below.

Step-by-step explanation:

r^2+12r-6=0

solve:

r^2 + 12 r + 36 - 36 - 6 = 0

factor the trinomial by completing the square.

( r + 6)^2 -42 = 0

(r + 6)^2 = 42

r + 6 = root(42 ) or r + 6 = - root(42)

r = -6 + root(42) or r = -6 -root(42)

Answer:

≈ 33°

Step-by-step explanation:

So, first, you can draw a visual. Refer to the image attached below:

Using this info, you can use trigonometric ratios. Recall that:

tangent = opposite side/adjacent side

sine = opposite side/ hypotenuse

cosine = adjacent side/hypotenuse

You can clearly see that you have an opposite side and a given hypotenuse. This means we'll be using sine.

So:

$sinX = \frac{150}{275}$

However, we're not trying to find sinX, we're trying to find X.

So we would have to use inverse sine, which would then be:

$X = sin-1 (\frac{150}{275} )$

Put this into your calculator, and:

X ≈ 33.05573115...

Answer:

The table C

Step-by-step explanation:

when you multiply the x number in the table c by 0.3 you get the same answer as the one in the y column. The constant of proportionality is the value that stays constant in the ratio. Since when you multiply each number in the x column by 0.3 and you always get the number in the y column it shows that the table c is correct.

Correct option is C. As used in line 50, "reason" most nearly means intellect.

write the logarithm as a sum or difference of logarithms. simplify each term as much as possible. log4(6ab)

Dominik [7]

The logarithm written as a sum of logarithm and simplified as much as possible is $\frac{1}{2} +log_{4 }3 + log_{4 }a + log_{4 }b$
