Expand the left side using the angle sum identity for sine:
sin(<em>x</em> + <em>π</em>/2) = sin(<em>x</em>) cos(<em>π</em>/2) + cos(<em>x</em>) sin(<em>π</em>/2)
cos(<em>π</em>/2) = 0 and sin(<em>π</em>/2) = 1, so the right side reduces to
sin(<em>x</em> + <em>π</em>/2) = cos(<em>x</em>)
as required.
Answer:
B and C
Step-by-step explanation:
Answer:
Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)
So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year
Step-by-step explanation:
Use the proportions from earlier
We have the point (5, 21000)
70,000/21,000 = 3.3
To find the x-value multiply 3.3 by 5
3.3 * 5 = 16.65
We can even use the other point's values to find the exact same answer
Point (3.5, 14700)
70,000/14,700= 4.7619047619
4.7619047619 * 3.5 = 16.66 (literally about the same)
The area of any circle is equal to
, where r is the radius.
We know that the diameter is 12. The radius is always half of the diameter, so the radius of our circle must be 6.
Substitute 6 for r in our equation and simplify.
π6² = π6×6 =
36π in²
Answer:
<u>108 m²</u>
Step-by-step explanation:
Area of the figure :
- 3 x 6 + (3 + 3) x 6 + (3 + 3 + 3) x 6
- 6 (3 + 6 + 9)
- 6 (18)
- <u>108 m²</u>
