Answer:
∠b = 64°
Step-by-step explanation:
We know that a complete rotation is 360°, so:
∠b + 57° + 239° = 360°
∠b = 360° - 57° - 239°
∠b = 64°
Answer:
y = -4/3x + 2
Step-by-step explanation:
to find slope use m= y2-y1/x2-x1
m= 3-(-1)/-6-(-3)
m= 4/-3
m= -4/3
then use point slope formula (y-y1) =m(x-x1)
(y-(-1)) = -4/3(x-(-3))
simplify
y+1 = -4/3x + 3
turn into slope intercept form
y = -4/3x + 2
Answer:
Only first two are exponential growth function and last three functions are exponential decay functions.
Step-by-step explanation:
We need to describe exponential growth or decay for the given functions.
The standard exponential function equation is
Where a is the initial value and b is the growth factor.
Note: If value of b > 1, it would be an exponential growth and if b < 1, it would be an exponential decay.
Value of b is 1.008 > 1, therefor it's an exponential growth function.
y=250(1+0.004)^t, also have b>1 therefor it's an exponential growth function.
All other functions has b values less than 1, therefore only first two are exponential growth function and last three functions are exponential decay functions.

Step-by-step explanation:
Answer:
x²-7 = 0 part 1 and part 2 : x = sqrt(7) or x = -sqrt(7)
Step-by-step explanation:
Solve for x:
x^2 - 7 = 0
Add 7 to both sides:
x^2 = 7
Take the square root of both sides:
Answer: x = sqrt(7) or x = -sqrt(7)
