This will be easier to write, and a lot easier to read, if we temporarily
use another symbol ... say, 'Q' ... to represent ' sin(2x) ' .
Here we go:
Original equation: Q² - 0.5 Q = 0
Factor the left side: Q (Q - 0.5) = 0
This equation is true if either factor is zero:
-- If Q=0, then sin(2x) = 0
2x = 0°, 180°, 360°
x = 0°, 90°, 180°
-- If (Q-0.5) = 0, then Q = 0.5
sin(2x) = 0.5
2x = 30°, 150°
x = 15°, 75°
The whole collection of solutions
between 0° and 360° :
x = 0°, 15°, 75°, 90°, 180° .
Answer:
6
Step-by-step explanation:
If c is 2 then that means you would multiply 2 and 3 to get 6
First you have to set the fractions with an equal denominator
hint: numerator/denominator
all of the denominators go into sixty
1/10=6/60
1/4=15/60
1/5=12/60
2/15=8/60
then you will have to add the numerators
(6+15+12+8)/60 = 41/60
simplify if possible but it's not necessary for this one
Tan(73) = tan(90 - 17) = cot(17) = 3.2709. Hope this helps you.
Answer:
1458 sq cm
Step-by-step explanation:
because each dimension of A is 3 tomes each dimension of B, that will mean that both the length and width of B are multiplied by 3 in order to get the length and width of A, so the area of B is length×width=162 and the area of A (in terms of B's dimensions) is 3xlength×3×width=9×length×width=9×162=1458 sq cm
