Look like B to me
It cant be C which has a negative slope.
Answer:
Step-by-step explanation:
We can solve that using this identity,
plug in -24/25 from x in sin
Since cos is positve in quadrant 4, the answer is 7/25.
ANSWER
EXPLANATION
The given vector is v = −14.5i + 2.5 j.
The magnitude of this vector is
The unit vector in the direction of this vector is
The area would be 83.67 cm.
A semicircle is half of a circle. The perimeter of the semicircle would be half of the perimeter (circumference) of the entire circle. The formula for circumference is:
C=πd
Using our information, we have
22.92 = 0.5(3.14)d
22.92 = 1.57d
Divide both sides by 1.57:
22.92/1.57 = 1.57d/1.57
14.6≈d
Since the diameter is 14.6, the radius is 14.6/2 = 7.3.
We use the radius for the area of the semicircle:
A=0.5πr²
=0.5(3.14)(7.3)²
=83.67
