From 1980 to 1990 the consumer price index increased from 82.4 to 130.7 if a bottle of dish soap cost 0.74 in 1980 and the price
natta225 [31]

Answer:

$0.43

Step-by-step explanation:

Rate of increase = [(CPI in 1990 / CPI in 1980)^1/t] - 1

(130.7 / 82.4)^1/10

1.586165^0.1 = 1.047213 - 1  = 4.72%

Price of dish soap in 1990 = value in 1980 ( 1 + rate of increase)^10

0.74( 1.047213)^10 = 1.174

Price increase 1.174 - 0.74 = 0.43

Which equation in point-slope form contains the point (2, 3) and has slope 2?
sergiy2304 [10]
------------------------------------------------------
Option A
------------------------------------------------------

------------------------------------------------------
Check if slope = 2
------------------------------------------------------
y + 2 = 2(x + 3)
y + 1 = 2x + 6
y = 2x + 6 - 1
y = 2x + 5

Slope = 2 

Answer:  Yes, Slope is 2

------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
When x = 2
y = 2(2) + 5
y = 9

Answer: No, it does not passed through (2, 3)

------------------------------------------------------
Option B
------------------------------------------------------

------------------------------------------------------
Check if Slope is 2
------------------------------------------------------
y - 3 = 2(x - 2)
y - 3 = 2x  - 4
y = 2x - 4 + 3
y = 2x - 1
Slope = 2

Ans : Yes, slope is 2.

------------------------------------------------------
Check if it passed through (2, 3)
------------------------------------------------------
when x = 2
y = 2(2) - 1
y = 4 - 1
y = 3

Answer : Yes, it passed through (2, 3)

------------------------------------------------------
Answer: (B) <span>y – 3 = 2(x – 2)

Need help with this the multiple choice questions aka &lt;&gt;,for each 3 of them are “makes sense, does not makes sense”
polet [3.4K]

When a 4 is rolled on the die, the player is awarded 17 points.

When a 4.5 is rolled on the die, the player is awarded 19 points.

When a 9 is rolled on the die, the player is awarded 37 points.

<h3>Function and values</h3>

Given the function that represents certain number of points is awarded to a player upon rolling a six sided die according to the function.

f(x) = 4x + 1

If the number of die rolled is 4, hence;

f(4) = 4(4) + 1

f(4) = 16 + 1

f(4) = 17

This shows that when a 4 is rolled on the die, the player is awarded 17 points.

If the number of die rolled is 4.5, hence;

f(4.5) = 4(4.5) + 1

f(4.5) = 18 + 1

f(4.5) = 19

This shows that when a 4.5 is rolled on the die, the player is awarded 19 points.

If the number of die rolled is 4, hence;

f(9) = 4(9) + 1

f(9) = 36 + 1

f(9) = 37

This shows that when a 9 is rolled on the die, the player is awarded 37 points.
