Answer:
A.
Step-by-step explanation:
This is A. because it says 5 TIMES the sum of b and two. First, the sum of b and two. That means it will be b+2. Now the 5. You have to multiply 5 by b+2. That means your answer is 5(b+2). If you follow the order of operations, you do what is in the parentheses first wish is b+2. Once you get the sum of that, you multiply it by 5.
Hope this helps! :)
Answer:
Step-by-step explanation:
To find the values of the angle which makes maximum r you use the derivative of r
If you equals this derivative to zero you obtain the value of the angle:
However, the values of 5π/6 and 9π/6 are also available, because makes the sinusoidal function equal to 1.
hence, the answer is:
answer b
Slope-intercept form: y = mx + c
10x - 5y = -17
move 10x to the other side.
- 5y = -10x - 17
Answer:
Cos A = 3/5
Step-by-step explanation:
Points to remember
<u>Trigonometric ratios
</u>
Sin θ = Opposite side/Hypotenuse
Cos θ = Adjacent side/Hypotenuse
Tan θ = Opposite side/Adjacent side
From the figure we can see a right angled triangle, ABC
AC = 9, CB = 12 and AB = 15
<u>To find the value of Cos A</u>
Cos A = Adjacent side/Hypotenuse
= AC/AB
= 9/15 = 3/5
Therefore the value of Cos A = 3/5
