Answer:
This is incorrect, the correct answer is 7/12
Step-by-step explanation:
It is after the fifth round that there are only 32 contestants left
1024/2=512
512/2=256
256/2=128
128/2=64
64/2=32
For a right triangle, we have he advantage of using the trigonometric functions like cosine and sine.
If you use cosine function:
cos45 = adjacent/hypotenuse
cos 45 = b/c
c = b/cos 45
If you use sine function:
sin 45 = opposite/hypotenuse
sin 45 = a/c
c = a/sin45
From the choices, the answer is <span>b over cos 45 degrees</span>
Answer:
x²+2x+3
Step-by-step explanation:
We are to simplify the expression;
5x³+10x²+15x/5x
Factor out 5x from the numerator
= 5x(x²+2x+3)/5x
5x will cancel out both at the top and bottom to have;
x²+2x+3
Factorize
x²+2x+3
Hence the simplified form is x²+2x+3
Answer: 18 yellow flowers
Step-by-step explanation:
There are 9 flowers in each of the 6 rows. The total number of flowers planted is therefore:
= 6 rows * 9 flowers per row
= 54 flowers
A 1/3 of these flowers were yellow flowers so the number of yellow flowers planted is:
= 1/3 * 54
= 54/3
= 18 yellow flowers
