Answer:
0.44
Step-by-step explanation:
See the picture below.
Remember that the sine is the ratio of the length of the opposite leg to the length of the hypotenuse.
Perhaps you know SOHCAHTOA, where SOH means sine, opposite, hypotenuse.
For angle J, leg LK is the opposite leg.
The hypotenuse of the triangle is the side opposite the right angle, teh angle of 90°, which is angle L, so the hypotenuse is side KJ.
Answer: 0.44
Answer:
Step-by-step explanation:
Birth Rate in 1994 = 14.6 births per thousand population.
Birth Rate in 2004 = 14.32 births per thousand population.
A linear equation is of the form: y=mx+c
Where:
- x=years after 1994
- y=the birth rate
- m=Yearly Birth Rate
First, we determine the birth rate per year
Therefore, a linear equation that relates y in terms of x is of the form:
When x=0, y=14.6
14.6=-0.028(0)+c
c=14.6
Therefore, the linear equation that relates y in terms of x is:
