First problem:
cos (theta)=1
Using the inverse cosine function, you get theta = 0.
Now we find tan 0 = 0
cot(theta) = 1/tan(theta) = 1/0
Division by zero is undefined, so the answer is d. undefined
Second problem:
cos (theta)=1
Use the inverse cosine function.
theta = 0°
Answer: c. 0°
The formula for a circumference of a circle is 2πr
2 × π × 25 = 157
so your answer is A 157in.
I hope I've helped!
Answer:
f(x) = 3x + 6.
Step-by-step explanation:
f(7) - f(0) = 27 - 6 = 21
so we may write a function:
f(x) = 3x + 6.
Answer:8tan(30)
Step-by-step explanation:
It is right angle triangle. The given data includes angle 30 and the side "b" infront i.e. perpendicular and the base 8ft.
So tan(30)=b/8
Seven more than 3 times a number is equal to 49 can be put into an equation form, which would be 7 + 3x = 49. With this equation we can work it out, first we will subtract 7 from both sides of the equation to cancel out the 7. 49 - 7 = 42. Now we have 3x = 42. To isolate x and give us the answer we will divide by 3 on both sides, since 3 is being multiplied by x. This will give us our answer, which is 14.
