If sec x = -3, and x lies in quadrant II, find tan
x/2

Answers

Answer:

√2.

Step-by-step explanation:

sec ^2x = 1 + tan^2 x

(-3)^2 = 1 + tan^2x

tan^2 x = 8

tan x = +/- 2√2

tan x/2 =  tanx / sec x + 1

= -2√2 /  -3 + 1

= -2√2 / -2

= √2

We take the negative tan  because tan is negative in the second quadrant.

A flower bed in the corner of your yard is in the shape of a right triangle. The perpendicular sides of the bed measure 7

a. 39.5 sq.ft
C. 21.5 sq.ft
b. 31.5 sq.ft
d. 11.5 sq. ft

Answers

B - 31.5 sq ft

9 ft x 7 ft = 63ft, but since we are finding the area of a triangle, not a square, we would divide that answer by 2, so:

63ft / 2 = 31.5 sq ft

Correct answer:

8cm

Explanation:

Because the two trapezoids are similar, the ratio of their bases must be the same. Therefore, we must set up a cross-multiplication to solve for the missing base:

6x=912, using x as the variable for the missing base.

72=9x

x= 8

Therefore, the length of the longer base of Trapezoid B is 8cm.

Simplify the expression ( 6x3-5x) + (2x3 + x 2+ 10x).​

Answers

Answer:

see below

Step-by-step explanation:

I assume when you write x3 you mean

[tex] {x}^{3} [/tex]

so the expressions is:

[tex](6{x}^{3} - 5x) + (2 {x}^{3} + {x}^{2 } + 10x)[/tex]

we can combine like terms

[tex]6 {x}^{3} + 2 {x}^{3} + {x}^{2} - 5x + 10x[/tex]

[tex]8 {x}^{3} + {x}^{2} + 5x[/tex]

the last thing we can do is factor out x because all 3 pieces have at least one x in them
