Answer:
The story of the man putting on grain of rice on a chess board is a great example of exponential growth.
Step-by-step explanation:
The man in the story said that "the king was to put a single grain of rice on the first chess square and double it on every consequent one."
Even though the number starts out small at first, it gets infinitely larger.
For example square 1 has 1 grain of rice, square 2, square 3 has 4, square 4 has 8, square 5 has 16 and so on.
The reason why the number got so large was because there are 64 squares on a chessboard, meaning the last square would have to hold 18,000,000,000,000,000,000 grains of rice!

Tra'Niyah spent half of the money she made babbysitting on mew shoes. If she baby sat for 6 hours and charged $8.75 per hour, how much money did she have left after shoe shopping
Answer:
She has $26.25 after shoe shopping
Step-by-step explanation:
if you multiply $8.75 by 6 hours, you get $52.50
then divide that by 2 and you get $26.25
Answer:
26.25 dollars
Step-by-step explanation:
8.75x6= 52.50
52.50/2 equals 26.25
Find the closest point on the line.
y = - x -4 to (4,4)
Answer:
(-2,-2)
Step-by-step explanation:
The closet point on a line to any given point is the point where a perpendicular line intersects them both. The perpendicular line to y=-x-4 that intersects (4,4) is y=x. If you graph them both, you will find that they intersect at (-2,-2).
Answer:
y = x - 4
Step-by-step explanation:
root (4,0)
domain XER
y intercept (0,-4)

Answer:
a) 13%
b) 65.9%
Step-by-step explanation:
a) You can use n=1 to find the percentage remaining at the end of 1 hour:
P = 100(0.87^1) = 87
This is 13% less than 100%, so the decay rate per hour is 13%.
__
b) Fill in n=3 and evaluate the expression.
P = 100(0.87^3) = 65.8503
After 3 hours, about 65.9% of the caffeine remains.
what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Liz lives 3 miles from the library.
Brendan lives 3 times as far as Liz.
Andy lives 3 times as far as Brendan.
Eddie lives 3 times as far as Andy.Which exponential expression represents how far Eddie lives from the library?
A.3 the the 5th power miles
B.4 to the 3rd power miles
C.3 to the 4th power miles
D.3 to the 3rd power miles
Answer:
C.
Step-by-step explanation:
3 times 3 =9 and is 3 by the 2nd power. Then that times three is 27 which is 3 to the third power. Now it’s time to find out where Eddie is compared to the library. Then that times 3 is 3 to the fourth power. So that’s how far Eddie is. He is 81 miles away.

the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
$1500 at 9% for 2 years
Answer:$270
Step-by-step explanation:
I=PRT

Determine the value of x in the triangle at the right.
Answer:
x = 72°
Step-by-step explanation:
This seems like a scalar triangle where 2 angles/sides are equal and the other is different.
Sum of all angles in a triangle equals 180 so using this we calculate x as follows:
[tex]x+x+36=180\\2x=144\\x=72[/tex]
so value of x = 72°

Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax = 11% * original price = 0.11 * x= 0.11xTips for dinner = 20% * original price = 0.20 * x = 0.2x0.11x + 0.2x = 18.600.31x = 18.60x = 60$60 was the price of Zoe's dinner, before sales tax and tip.Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
1. Sales tax = 11% times original price = 0.11 times x= 0.11x
2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x
3. 0.11x + 0.2x = 18.60
4. 0.31x = 18.60
5. x = 60
6. $60 was the price of Zoe's dinner, before everything else
