First of all Horner
First we try with -3
1. 2. -5. -6.
-3. 3. 6
1. -1. -2. 0
To verify: -3^3+2*-3^2+15-6=0
Now we have this equation
(X+3)*(x^2 - x -2)=0
I dont know If you know sum and product but that is the easiest way so sum= 1 product = 2 so 2 and -1 are the answers.
You can do this too by this way : b^2-4ac= D
X= (-b(+or-)d^1/2)/2a
So all the zeros
2, -1 and -3

Answer:
f(x)=0.17x+3.00
f(60)=0.17(60)+3.00
f(60)=10.20+3
f(60)=13.20
1 hour will cost $13.20
Step-by-step explanation:
I found the difference in minutes between the given values and the difference in cost between the given values. Between 8 minutes and 25 minutes is 17, and between 25 and 40 is 15 minutes. The difference of $7.25 and $4.36 is $2.89, and the difference between $7.25 and $9.80 is $2.55. I then divided2.89 by 17 and 2.55 by 15 and both resulted in $0.17/minute. I them multiplied 8 minutes by $0.17 toget $1.36. I subtracted that from the cost given for 8 minutes to get $3.00. The $3.00 is the initial charge, or b in slope-intercept form with m=0.17. Plug in 60 for x to find the cost of an hour.
Hey there! :)
Answer:
Choice D. V = 2184 in³.
Step-by-step explanation:
Recall that to find the volume of a rectangular prism, the following formula is used:
V = l × w × h
Plug in the given dimensions into the formula to solve for the volume:
V = 14 × 13 × 12
Multiply:
V = 2184 in³. The correct answer is D.
Answer:2+2= fish
Step-by-step explanation:
put the first one up side ways this side up --->2 and for the 2nd one this side down ---->2 then it looks like a fish your welcome ugh
If you would like to know how long will take you to paint one wall, you can calculate this using the following steps:
1/3 of a wall ... 1/4 hour1 wall ... x hours = ?
1/3 * x = 1/4 * 11/3 * x = 1/4 /*3x = 1/4 * 3x = 3/4 hour
Result: It will take you 3/4 hour to paint one wall.
