The numbers 0.1, 12, 15 and 124 can all be classified as counting numbers?​
andreyandreev [35.5K]

Answer:

No

Step-by-step explanation:

Counting numbers are considered to be whole numbers greater than zero. Whole numbers are positive numbers without decimals or fractions, so 12, 15, and 124 can be classified as counting numbers, but not 0.1.

hope this helps!!!

Calculate the average rate of change for the function f(x) = x4 + 3x3 - 5x2 + 2x - 2, from x = -1 to x = 1
kolezko [41]
In interval <a, b>  the average rate of change the function you count from this formula:
x=\frac{f(b)-f(a)}{b-a} \qquad b>a
Here you've got a=-1 and b=1:
f(a)=f(-1)=(-1)^4+3 \cdot (-1)^3 - 5 \cdot (-1)^2 +2 \cdot (-1)-2= \\ = 1-3-5-2-2=-11 \\ \\ f(b)=f(1)=1^4+3 \cdot 1^4 - 5 \cdot 1^2 + 2 \cdot 1 -2=1+3-5+2-2=-1 \\ \\ \hbox{So average rate of change this function is:} \\ \\ x= \frac{-1+11}{1+1}=\frac{10}{2}=5

Eric, Cam, and Brooke are playing a game of mini golf on a computer. The computer program for the game stores
andrew-mc [135]

Answer:

Eric

Step-by-step explanation:

First, we determine the distance of each player to the hole using the distance formula.

Given points (x_1,y_1)$ and (x_2,y_2)

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

<u>Eric</u>

The hole is at (3,2)

Eric's golf ball is at point (-6,6)

Distance=\sqrt{(-6-3)^2+(6-2)^2}

=\sqrt{(-9)^2+(4)^2}\\=\sqrt{97} \\\approx 9.85

<u>Cam</u>

The hole is at (3,2)

Cam's golf ball is at point (8,-6)

Distance=\sqrt{(8-3)^2+(-6-2)^2}

=\sqrt{(5)^2+(-8)^2}\\=\sqrt{89} \approx9.43

<u>Brooke</u>

The hole is at (3,2)

Brooke's golf ball is at point (10,8)

Distance=\sqrt{(10-3)^2+(8-2)^2}\\=\sqrt{(7)^2+(6)^2}\\=\sqrt{85} \approx 9.22

Since Eric's ball is the farthest from the hole, Eric should shoot next.
