Answer:
BC ≈ 4.85 m
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos26° =
=
=
( cross- multiply )
5.4 × cos26° = BC , then
BC ≈ 4.85 m ( to 3 s f )
Answer:
No.
Step-by-step explanation:
If (0,5) is a solution to y=2x, then 5=2(0) has to be true.
It is not because 5=2(0) is not true.
2(0)=0 and 0 is definitely not 5.
An example of a point on y=2x is (5,10) since 10=2(5) is true.

Positive square root of 0.25 = 0.5

Answer:
C = 22π; A = 121π.
Step-by-step explanation:
To find the circumference of a circle, you do pi times the diameter. That would be 22pi.
To find the area of a circle, you do pi * r^2. The radius is the diameter divided by 2. That is 22 / 2, which is 11. Then, the area would be pi * 11^2 = pi * 121 = 121pi.
So, C = 22pi; A = 121pi.
