Calculate a and b if

const2013 [10]

Notice that

$7^{2014} - 7^{2012} = 7^{2012} \bigg(7^2 - 1\bigg) = 7^{2012} \times 48 = 2^4 \times 3 \times 7^{2012}$

$12=2^2\times3$ , so

$\dfrac{7^{2014}-7^{2012}}{12} = 2^2 \times 7^{2012}$

Then taking the positive square root gives

$\sqrt{\dfrac{7^{2014}-7^{2012}}{12}} = \sqrt{2^2 \times 7^{2012}} = 2\times7^{1006}$

so $\boxed{a=2}$ and $\boxed{b=1006}$ .

Number 28 ignore the bubbled in answer

Ghella [55]

Answer:

y = -7x+34

Step-by-step explanation:

We have 2 points, so we can find the slope

m = (y2-y1)/(x2-x1)

= (6--1)/(4-5)

= (6+1)/(4-5)

= 7/-1

= -7

We can use point slope form to make an equation

y-y1 = m(x-x1)

y--1 = -7(x-5)

y+1 = -7(x-5)

Distribute

y+1 = -7x+35

Subtract 1 from each side

y+1-1 = -7x+35-1

y = -7x+34

PLEASE HELP LAW OF COSINES

chubhunter [2.5K]

The Law of Cosine states
cos $C=(a^2+b^2-c^2)/2ab$

so plugging in the numbers gives us

cos $J=(13^2+19^2-11^2)/2(13*19) = 409/494$

We now have cosJ so plug that into your calculator and find arccos (arccos(cos(J)) = J)
arccos $(409/494)=34.11$
rounding your answer will give you 34°
