express -32/243 into power notation
This problem can take a while if you cannot observer the answer quickly.
First of all we can see that 32=2*2*2*2*2=2^5
243, if you don't know its actually is 3^5
Now we can see that this turns into...
- 2^5/3^5
since the 5th power doesn't change the sign of the original number, we can put the negative in the ( ), if you don't know what I mean look below
(-3)^2=9 Positive
(-3)^3=-27 Negative since its to the odd power it keeps the sign.
This problem can be simplified to.
(-2/3)^5
And this is the answer :D

-4m^2+2m-11=-5m^2
Answer:
m is equal to -1 ± 2√3, which is approximately equal to 2.46 and -4.46
Step-by-step explanation:
-4m² + 2m - 11 = -5m²
m² + 2m - 11 = 0
m² + 2m + 1 = 12
(m + 1)² = 12
m + 1 = ± √12
m = -1 ± 2√3

You ride through some wet paint on your bike, creating a red
spot on the tire. Write a cosine equation to model the height
of the red spot over the distance you ride.
• Your bike tire has a radius (r) of 13 inches
• The period is the circumference of the tire (2 πr)
• Start the cycle when the spot is at the top of the tire
Answer:B
y=13cos(1/13x)+13
Step-by-step explanation:
The cosine equation to model the height of the red spot over a distance you ride is y = 13 cos (x/13) + 13. Then the correct option is B.
What is a cosine Function?It is a function that repeats itself in a particular time interval.
You ride through some wet paint on your bike, creating a red spot on the tire.
Write a cosine equation to model the height of the red spot over the distance you ride.
Your bike tire has a radius (r) of 13 inches.
The period is the circumference of the tire (2πr).
The cosine equation is given as
y = A cos (Bx + C) + D
Where
A = the amplitude
B = time period
C = phase difference
D = shifting of central line
Then we have the diagram
A = 13
B = 1/13
C = 0
D = 13
Then the equation will be
[tex]\rm y = 13 \cos (\dfrac{1}{13}x - 0 ) + 13\\\\y = 13 \cos (\dfrac{x}{13} ) + 13[/tex]

Find the area of the shaded section.
3 cm
9 cm
7 cm
16cm
Answer:
The area of the shaded portion is 123 cm^2
Step-by-step explanation:
Here, we want to find the area of the shaded portion
To find this, we subtract the area of the smaller inner rectangle from that of the outside bigger one
Mathematically, the area of a rectangle at any point in time is length * width
For the bigger one, we have;16 * 9 = 144 cm^2
For the smaller inner one, we have ;3 * 7 = 21 cm^2
The area of the shaded portion which is the difference is;
144-21 = 123 cm^2
5. A softball has a diameter of 8.3 in. How many softballs will fit inside of a storage unit 4 that is 15 feet wide, 10 feet long, and 5 feet high?
Answer:
4329 softballs
Step-by-step explanation:
To find the number of softballs that will fit into the container, we first find the volume of the softball. Since it is a sphere, its volume V = 4πr³/3 where r = radius = d/2 where d = diameter of softball.
So, V = 4π(d/2)³/3 = πd³/6
Since d = 8.3 in,
V = πd³/6 = π(8.3 in)³/6 = π × 571.787 in³/6 = 299.39 in³
The volume of the box, V' = 15 × 10 × 5 ft³ = 750 ft³ = 750 × (12 in)³ = 750 × 1,728 in³ = 1,296,000
So, for n softball to fit, its volume must equal the volume of the storage unit.
The volume of n softballs is nV.
For the softballs to fit, V' = nV
n = V'/V
= 1,296,000 in³/299.39 in³
= 4328.8 softballs
≅ 4329 softballs since we cannot have a decimal number of softballs.

Answer:
The surface area is 286.5in.
Step-by-step explanation:
7.5 * 11.5 = 86.25 * 2 = 172.5in for two big rectangles
7.5 * 3 = 22.5 for little rectangle
11.5 * 3 = 34.5 * 2 = 69 for two medioum rectangles
7.5 * 3 = 22.5 for the smallest rectangle
22.5 + 69 + 22.5 + 172.5 = 286.5 in SA

so 1:1 x 473:473 = 473:473
Therefore there are 473 potatoes
Answer:
473 potatoes
Step-by-step explanation:
The ratio is 1:1, meaning that for every carrot, there is a potato.

Which algebraic expression represents “the quotient of 7 and a number”?
Answer: D
Step-by-step explanation: its best you can get to the a quotient (from Latin: quotiens "how many times", pronounced) is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division (in the case of Euclidean division), or as a fraction or a ratio (in the case of proper division). For example, when dividing 20 (the dividend) by 3 (the divisor), the quotient is 6 in the Euclidean division sense, and 62/3 in the proper division sense.
