1) we know that sin2x=2sinxcosx, so sinxcosx=(1/2)sin2x, but sinxcosx=0.027
(1/2)sin2x=0.027, sin2x=0.054, arcsin(0.054)=2x, 3.09=2x, x=1.54 degree (x is in (0, 2), it is verified)
Answer:
y = -3x + 2, or C
Step-by-step explanation:
So, slope intercept form is y = mx + b.
m = (y2 - y1)/(x2 - x1). So (5 - (-1))/(-1 - 1) = -3
b = (0,2), according to the graph, or just 2.
So y = -3x + 2
Answer:
19530 meters
Step-by-step explanation:
There are 7 days per week. If audrina swims 21 times for 0.93 km each day, we can multiply 0.93 km by 21 as we add 21 instances of 0.93. Our answer, using a calculator, is 19.53 km. Multiplying that by 1000, as there are 1000 meters per kilometer, we get 19530 meters as our answer
Answer:
?
Step-by-step explanation:
First you do,
3 x 2 =1/4
plus 3 x 2 1/2= ?
Then you will get your answer! Hope it helps!
The would be -3,, because your doing y2-y1 over x2-x1
