So this first wants you to find where sin is √3/2 when θ is between π and 3π/2. θ would therefore be located at 2π/3.
Now plug in the value of θ for cosine:
cos (2π/3) = -1/2
And tangent:
tan (2π/3) = -√3/3
Answer:
using a negative facto to factor the expression will be:
- 7a+49b - 35 = -7(a-7b+5)
Step-by-step explanation:
Given the expression
- 7a+49b - 35
Rewrite -35 as 5 · 7
Rewrite 49 as 7 · 7
so
= -7a + 7 · 7b - 5 · 7
as -7 is the common factor, so factoring out
= -7(a-7b+5)
Thus, using a negative facto to factor the expression will be:
- 7a+49b - 35 = -7(a-7b+5)
Answer:
-22 1/2
Step-by-step explanation:
-2 1/2 *s
Let s = 9
-2 1/2 (9)
Change to an improper fraction
-5/2 *9
-45/2
Change back to a mixed number
-22 1/2
Answer:
C. 10in 24in 26in
Step-by-step explanation:
Right Scalene Triangle
Side a = 24
Side b = 10
Side c = 26
Angle ∠A = 67.38° = 67°22'48" = 1.17601 rad
Angle ∠B = 22.62° = 22°37'12" = 0.39479 rad
Angle ∠C = 90° = 1.5708 rad = π/2
Area = 120
Perimeter p = 60
Semiperimeter s = 30
Height ha = 10
Height hb = 24
Height hc = 9.23077
Median ma = 15.6205
Median mb = 24.5153
Median mc = 13
X=-8 is just a vertical line 8 units to the left of the origin.
So a parallel line will also be vertical and as asked it must pass through (-3,-1) so it is:
x=-3
