Answer:

-12

Step-by-step explanation:

The average rate of change of a function f(x) on an interval [a, b] is defined as ...

average rate of change = ((f(b) -f(a))/(b -a)

For the given function and interval, this is ...

average rate of change = (f(1.25) -f(0.75))/(1.25 -0.75)

= (4 -10)/(0.5) = -12

The average rate of change is -12 on the interval.

The calculator results for f(1.25) and f(0.75) are shown in the attachment, along with the computation of the average rate of change.

Prove the following

jenyasd209 [6]

Answer:

Step-by-step explanation:

sin(180°-∅)=sin∅ as its in the 2nd quadrant

then tan(180°-∅)= -tan∅ as its in the 2nd quadrant and there only sin and cosec is positive and at last cos(180°-∅) = -cos∅ for the same reason

so by putting the values:

sin∅/sin∅ + -tan∅/tan∅ + -cos∅/cos∅ =1-1-1= -1

Use the Factor Theorem to determine if the given binomial is a factor of the given polynomial function:f(x)=4x^4-20x^3+33x^2-22x

Xelga [282]

Answer:

D: f(5/2)=0; yes, the binomial is a factor of the polynomial

Step-by-step explanation:

The easy way to determine is to plug in the potential zero into the polynomial given the binomial divisor and see if it results in 0. If so, then the binomial is a factor of the polynomial:

Because f(5/2)=0, then the binomial is indeed a factor of the polynomial!
