Answer:
Step-by-step explanation:
1.
(a) n ≤ 21
(b) n ≥ 5
(c) n > 3/5
2.
(d) n < 14
(e) n ≥ 14
Given 2 sides and 1 included angle, the area of a triangle can be solved using the formula:
Area = ab (sin C)/2
Substituting the given values:
Area = 10 * 23 * (sin 95)/2
Area = 114.56 sq. units
Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
90+85=175
Thats the answer
28 + vector b = -12
vector b = -40
vector b has magnitude 40 units in the negative y direction.
