What is the length of side c, given a = 10, b = 8, and c = 105°?

posledela

We can calculate using cosinus method in triangle
c² = a² + b² - 2ab cos c

Plug in the number to the formula
c² = a² + b² - 2ab cos c
c² = 10² + 8² - 2(10)(8) cos 105°
c² = 100 + 64 - 160 cos 105°
c² = 164 - 160 (-0.26)
c² = 164 + 41.6
c² = 205.6
c = √205.6
c =14.34

C is 14.34 unit length

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!

Sedbober [7]

For f(-2), x will equal -2.

Plug the x-value into the equation:

$2 \times 2^{-2}$

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator.
Solve 2^(-2):

$2^{-2} = \frac{1}{2^{2}} = \frac{1}{4}$

Solve the problem:

$2 \times \frac{1}{4} = \frac{1}{2}$

f(-2) will equal 1/2.
