Given sec theta=-4/3 and 90°

hoa [83]

Answer:

Option A.

Step-by-step explanation:

It is given secθ = - $\frac{4}{3}$

then cosθ = - $\frac{3}{4}$

Now we know the identity

sinθ = $\sqrt{1-cos^{2}\theta }$

= $\sqrt{1-(-\frac{3}{4} )^{2}}$

= $\frac{\sqrt{7} }{4}$

Now sin2θ = 2sinθcosθ

Now we put the values of cosine and sine in the formula

sin2θ = 2×(- $\frac{3}{4}$ )( $\frac{\sqrt{7}}{4}$ )

= - $\frac{3\sqrt{7}}{8}$

Therefore, option A. is the answer.

If f(x) = 4 – x2 and g(x) = 6x, which expression is equivalent to (g – f)(3)?

tatiyna

F(x) = 4 - x² g(x) = 6x

(g - f)(x) = g(x) - f(x)

(g - f)(3) = g(3) - f(3)

g(x) = 6x

g(3) = 6*3 = 18

f(x) = 4 - x²

f(3) = 4 - 3² = 4 - 9 = -5

(g - f)(3) = g(3) - f(3) = 18 - (-5) = 18 + 5 = 23

(g - f)(3) = 23

Easy points

goblinko [34]

Answer: 2

Step-by-step explanation:

try each value in the equation

2(0) + 1 = 3

0 + 1 = 3

1 ≠ 3

so 0 doesn’t work

2(1) + 1 = 3

2 + 1 = 3

3 = 3

this works, so the answer is 1
