Answer:

Hence, the rate of change of f(x) from x=1 to x=3 is given by:

-4

Step-by-step explanation:

We have to find the rate of change of the function f(x) from x=1 to x=3 which is defined as:

f(x)=-(3)^{x-1}+3

The rate of change of the function f(x) from x=1 to x=3 is given by:

\dfrac{f(3)-f(1)}{3-1}

we know that:

f(1)=-(3)^{1-1}+3\\\\f(1)=-(3)^0+3\\\\f(1)=-1+3\\\\f(1)=2

Similarly,

f(3)=-(3)^{3-1}+3\\\\f(3)=-(3)^2+3\\\\f(3)=-9+3\\\\f(3)=-6

Hence, the rate of change is given as:

\dfrac{-6-2}{3-1}\\\\=\dfrac{-8}{2}\\\\=-4

Hence, the rate of change of f(x) from x=1 to x=3 is given by:

-4

The rate of the change for the function between points x=1 and x=3 will be given by:
[f(3)-f(1)]/(3-1)
f(3)=-6
f(1)=2

thus the rate of change will be:
(-6-2)/(3-1)
=-8/2
=-4
Answer: -4

jeds market has a total of 26 employees. Each full time employee makes $275/ week, and each part-time employee makes $140/ week.
I am Lyosha [343]

Answer:

f=17\\p=9\\

Step-by-step explanation:

Let

f= Full-time\\p=Part-time

Full time rates-$275, Part-time rates-$140

The problem can be expressed as:

f+p=26...eqtn1\\275f+140p=5935....eqtn2\\

Express eqtn1 in terms of f,f=26-p

Substitute f value in eqtn 2.

=>275(26-p)+140p=5935\\7150-275p+140p=5935\\1215=135p\\p=9\\f=26-9=17\\

Therefore,  jeds has 17 fulltime and 9 parttime employees.

O. Find the distance between P (10,-7) and Q (7,- 10). Leave your answer in radical<br> form.
mr Goodwill [35]

Answer:

\sqrt{18} or 3\sqrt{2} units.

Step-by-step explanation:

To find the <em>distance between two points</em>, we can use the Distance Formula.

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u />

<u>Given:</u>

P (10, -7) ⇒ x₁ = 10, y₁ = -7

Q (7, -10) ⇒ x₂ = 7, y₂ = -10

Substitute the given values into the formula and simplify.

\\\implies d=\sqrt{\bold{(7-10)}^2+\bold{(-10-(-7))}^2}\\\\\implies d=\sqrt{\bold{(-3)}^2+\bold{(-10+7)}^2}\\\\\implies d=\sqrt{9+\bold{(-3)}^2}\\\\\implies d=\sqrt{\bold{9+9}}\\\\\implies d=\sqrt{\bold{18}}\\\\\implies d=\sqrt{\bold{9}\times2}\\\\\implies d=3\sqrt{2}

The distance between points P and Q is \sqrt{18} or 3\sqrt{2} units.
