   tangent(x) = (opposite side) / (adjacent side)

   = (57 / 29)

   = 1.96551....

According to my calculator,

   The angle whose tangent is 1.96551... = 63.034... degrees .

The nearest whole degree = 63 degrees.

Find the product. (a3 + 8)(a3 – 8)

kogti [31]

1. Use difference of squares: a^2-b^2=(a+b)(a-b)
(a^3)^2-8^2
2. Use power rule: (x^a)^b=x^(ab)
a^6-8^2
3. Simplify 8^2 to 64
a^6-64

Your answer is d.

2 1/4 - 2/3. A. 1 3/7. B. 1 7/12. C 2 3/7. D 2 11/12

DedPeter [7]

Answer:

B.) $1\frac{7}{12}$

Step-by-step explanation:

$2\frac{1}{4} -\frac{2}{3} Then multiply 4 by 2, then add 1.frac{9}{4} - \frac{2}{3} \\$

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

$\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}$

to get: $\frac{27}{12} - \frac{8}{12}$ .

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: $\frac{19}{12} = 1\frac{7}{12}$ .

Your final answer is 1\frac{7}{12}[/tex].
