Ethan's string is 4/3 of Kayla's string.
4/3 + 3/3 = 7/3
10/7 = 1.42857143
1.42857143*4 = 5.71428571
1.42857143*3 = 4.28571429
5.71428571 + 4.28571429 = 10
Ethan's string is 1.42857143ft longer than Kayla's

Find the measures of two angles, one positive and one negative that are coterminal with pi/5
lozanna [386]
To find coterminal angles for an angle, β, given in radians use the following formula:
                                  coterminal angle =  β + 2πk
                          where k is an integer {..., -3, -2, -1, 0, 1, 2, 3, ...}
Negative Coterminal Angle: k = -1 
                                   NCA = π/5 + 2π(-1)
                                            = -9π/5      
Positive Coterminal Angle: k = 1
                                  PCA = π/5 + 2π(1)
                                           = 11π/5
The following answers are just one of many possible answer... you have infinite number of choices for k.
NCA =  \frac{-9 \pi }{5}
PCA= \frac{11 \pi }{5}

If f(x) = 3x -2 and g(x).= 4x + 1.<br> what is the sum of f(2) and g(-3)
ira [324]

Answer:

The sum of f(2) and g(-3) is -7.

Step-by-step explanation:

f(x) = 3x - 2

f(2) = 3(2)-2

f(2) = 6 -2 = 4

g(x) = 4x + 1

g(-3) = 4(-3) +1

g(-3) = -12 + 1 = -11

f(2) + g(-3) = 4 + (-11)

f(2) + g(-3) = -7
