Answer:
45 and 225degrees
Step-by-step explanation:
Given the expression
tan⁻¹1
Using the calculator
tan⁻¹1
tan⁻¹1 = 45degrees
Since tan is positive in the third quadrant
theta= 180 + theta
theta = 180 + 45
theta = 225degrees
Hence the values of theta are 45 and 225degrees
Answer: B
Step-by-step explanation:
From the given table
When x changes from 1 to 2 , value of y changes from 6 to 4
The multiplicative rate of change=
Similarly we can check
When x changes from 2 to 3 , value of y changes from 4 to
The multiplicative rate of change=
When x changes from 3 to 4 , value of y changes from to
The multiplicative rate of change=
Therefore, the multiplicative rate of exponential function =
1 nickel = 5 cents
1 dollar = 20 nickels
You can make 13 dollars plus 16 nickels left over
20 * 13 = 260
then 260 + 16 = 276
Y = k/x is the inverse equation.
6 = k/11
Solving for k, multiply by 11 on both sides.
66 = k
y = 66/x
13.2 = 66/x
x = 5
Answer:
They did not flip the inequality
Step-by-step explanation:
-x/4 < (x+2)/3
Multiply each side by 3
-3x<4x+8
Subtract 4x from each side
-3x-4x <4x-4x +8
-3x-4x<8
Combine like terms
-7x<8
Divide by -7. Remember to flip the inequality
-7x/-7 > 8/-7
x > -8/7
