Answer:
960 cubes
Step-by-step explanation:
To find how many cubes of side 1 foot can be contained in the room, we have to find the volume of the storage room and then, divide by the volume of the cube.
The storage room is in the shape of a rectangular prism, hence, its volume is:
[tex]V = L * W * H[/tex]
where L = length
W = width
H = height
The dimensions of the storage room are:
10 feet wide, 12 feet long, and 8 feet high
Hence, its volume is:
[tex]V = 10 * 12 * 8 = 960 ft^3[/tex]
The volume of the cube of side 1 foot is:
[tex]V = S^3\\\\V = 1^3 = 1 ft^3[/tex]
Hence, the number of cubes that can be contained in the storage room is:
960 / 1 = 960 cubes
960 cubes can be stored in the storage room.

what is the general solution to the differential equation dy/dx= cos(8x)/cos(4y) ?
A. sin =(4y) - sin(8x) = C
B. sin (4y) - 2 sin(8x) = C
C. 2 sin(4y) - sin(8x) = C
D. 2 tan(4y) - sin(8x) = C
Answer:
2sin4y - sin8x = K (C)
Step-by-step explanation:
Given the differential equation
dy/dx= cos(8x)/cos(4y)
This can be solved by using the variable separable method.
Step 1;
Separate the variables
Cos4ydy = cos 8xdx
step 2:
Integrate both sides of the equation
∫cos4y dy = ∫cos8x dx
sin4y/4 = sin8x/8
Step 3:
Add constant of integration to the side containing x variable
sin4y/4 = sin8x/8+ C
Taking sin8x to the other side we have:
sin4y/4-sin8x/8 = C
Multiplying through by 8:
2sin4y - sin8x = 8C
2sin4y - sin8x = K (where K = 8C )
To solve the given differential equation we have apply variable separation method.
The correct option is (c) 2 sin(4y) - sin(8x) = C.
Variable separation:In mathematics, variable separation method used to calculate the partially and ordinary differential function in which we rewrite the equation so that two variable occurs on two side.
Given:
The given differential equation is as follows,
[tex]\dfrac{dy}{dx}=\dfrac{\cos(8x)}{\cos(4y)}[/tex]
How to calculate the Separate the variable?Separate the variable.
[tex]\cos 4y \:dy =\cos 8x\:dx\\[/tex]
Integrate both side of the equation.
[tex]\int \cos4y dy = \int \cos8x dx\dfrac {1}{4}\sin4y = \dfrac {1}{8}\sin8x\\\dfrac {1}{4}\sin4y-\dfrac {1}{8}\sin8x=C\\2\sin4y - \sin8x = 8C[/tex]
Thus, the correct option is (c) 2 sin(4y) - sin(8x) = C.

Suppose vanilla beans cost $600 per kilogram. Julie bought 9 grams of vanilla beans. Jacques bought 70 grams of vanilla beans. How much more did Jacques pay for his vanilla beans? A.$5.40 B.$12.00 c.$36.60 D.$42.00
Answer:
The correct option is c,$36.60
Step-by-step explanation:
The key to solving this question lies around measurement conversion,specifically converting grams into its equivalence in kilograms.
1000 grams equal one kilogram
9 grams=9/1000 kg
9 grams=0.009 kg
70 grams=70/1000 kg
70 grams=0.07 kg
Julie pays=$600*0.009=$5.4
Jacques pays=$600*0.07=$42
Jacques pays $36.60 more ($42-$5.4) than Julie paid
Option is wrong because that was what Julie paid
Option D is wrong because that was what Jacques paid
Option B is obviously wrong

Write your answer in the form y=mx+b.
I don't get it please help!
Answer:
y = -2x+2
Step-by-step explanation:
First we find the slope
m = (y2-y1)/(x2-x1)
= (-2-4)/(2--1)
= (-2-4)/(2+1)
-6/3
-2
We have the slope =-2
We can substitute it into the equation
y = mx+b where m is the slope and b is the y intercept
y =-2x+b
Use a point for x and y to solve for b
4 = -2(-1) +b
4 = 2+b
Subtract 2 from each side
4 -2 = -2+2+b
2 = b
We know m and b
y = -2x+2
Answer:
y = -2x + 2
Step-by-step explanation:
Slope: (-2-4)/(2--1) = -6/3 = -2
y - 4 = -2(x - -1)
y = -2x - 2 + 4
y = -2x + 2
When graphed, which parabola opens downward?
y = –3x2
y = (x – 3)2
y = one-third x squared
y = x2 – 3
The parabola that opens downward when graphed is y = –3x^2, as the negative coefficient of the x^2 term determines the downward opening direction.
The student has asked which parabola opens downward when graphed. The general form of a parabola is y = ax2 + bx + c. The direction in which the parabola opens is determined by the coefficient a of the x2 term. If a is negative, the parabola opens downward, and if a is positive, the parabola opens upward. Looking at the provided equations, we can identify the equation with a negative a value:
y = –3x2 (The coefficient of the x2 term is -3, so this parabola opens downward.)y = (x – 3)2 (The coefficient here is positive after expanding, so this parabola opens upward.)y = one-third x squared (The coefficient is positive 1/3, so this parabola opens upward.)y = x2 – 3 (The coefficient is positive 1, so this parabola opens upward.)Therefore, the equation of the parabola that opens downward when graphed is y = –3x2
Write one digit on each side of 92 to make a four digit multiple of 45. How many different solutions does this problem have?
Answer:
Two solutions:
Adding 7 to the left and 0 to the right: 7920
Adding 2 to the left and 5 to the right: 2925
Step-by-step explanation:
The multiples of 45 always have as last digit 0 or 5, so the digit to the right of 92 has to be 0 or 5.
If we use 0 as the last digit, our options of multiples will be just 7920 (7920 = 45 * 176)
If we use 5 as the last digit, our option of multiples will be just 2925 (2925 = 45 * 65)
So we have just two solutions for this problem:
Adding 7 to the left and 0 to the right: 7920
Adding 2 to the left and 5 to the right: 2925
Which polynomial function has a leading coefficient of 1, roots -2 and 7 with multiplicity 1, and root 5 with multiplicity 27
O
f(x) = 2(x + 7)(x + 5)(x-2)
Rx) = 2(x - 7)(x - 5)(x + 2)
Rx) = (x + 7)(x + 5)(x + 5)(x - 2)
f(x) = (x - 7)(x - 5)(x - 5)(x + 2)
The polynomial function with a leading coefficient of 1 and the specified roots and multiplicities is f(x) = (x + 2)(x - 7)(x - 5)^27.
Explanation:The polynomial function you are looking for, which has a leading coefficient of 1, roots at -2 and 7 each with a multiplicity of 1, and a root at 5 with multiplicity 27, is given by the expression:
f(x) = (x + 2)(x - 7)(x - 5)^27
The given roots indicate the factors of the polynomial, and the multiplicity of each root shows how many times that factor is repeated. Hence, the root -2 becomes (x + 2), the root 7 becomes (x - 7), and the root 5 with multiplicity 27 becomes (x - 5)^27. The leading coefficient is 1, which means these factors are not multiplied by any other constant.

Andrea has a credit score of 895 and Ashley has a credit score of 768. Stutts National Bank has determined that both will receive a credit card; however, the borrower with the lower credit score will be charged a $50.00 fee the first time she makes a purchase. If both receive a credit card with $1,500.00 available credit, what will Ashley's remaining available credit be after she purchases a $425.00 Coach bag?
Answer:
Ashley's remaining available credit after her first purchase is $1025.00
Step-by-step explanation:
Here we are told that the borrower with the lower credit score will be charged $50.00 fee after the first purchase
Therefore, we have
Credit score Andrea = 895
Credit score for Ashley = 768
Therefore, Ashley has the lower credit score hence after her first purchase of a $425.00 Coach bag, we have
Available credit = Initial balance - Purchase - Charges
∴ Available credit = $1,500.00 - ($425.00 + $50.00) = $1025.00
Therefore, Ashley's remaining available credit after she purchases the $425.00 Coach bag = $1025.00.

please help!
Answer:
121 + 22i - 1
Step-by-step explanation:
Expand:
(11 + i)² = (11 + i)(11 + i)
Note that:
i² = -1
Use FOIL method. Multiply first terms, outside terms, inside terms, then the last two terms:
(11)(11) = 121
(11)(i) = 11i
(i)(11) = 11i
(i)(i) = -1
Combine like terms:
121 + 11i + 11i - 1
121 + (11i + 11i) - 1
121 + 22i - 1
121 + 22i - 1 is your answer.

1. Complete the inequality below to describe the
domain of the graph shown.
Domain
2. Complete the inequality below to describe the
range of the graph shown.
Range: <_y <5
Domain is the entire span left to right (on the x-axis) that the graph is on. Since the graph goes from x=-4 and ends at x=4, the domain would be from -4 to 4. The circle at -4 is open, so it does not include the point at -4, just everything leading up to it. So, the domain would be
[tex] - 4 < x \leqslant 4[/tex]
The range is similar, it is the entire span that the graph goes up and down (on the y-axis). The graph starts at the bottom at y=-2, and ends at y=5. The bottom point (4,-2) is closed, so the graph includes that point, and the top point (-4,5) is open and doesn't include the point. Therefore, the range would be
[tex] - 2 \leqslant x < 5[/tex]

The width of a swimming pool is 12 feet less than the pool's length. The area of the pool is 540 square feet. What are the dimensions of the pool?
Answer:
30 feet by 18 feet
Step-by-step explanation:
Area = length * width
A = x*w
w = x - 12
A = 540 sq. ft
540 = x * (x -12)
x*x - 12x - 540 = 0
x*x - 12x + 36 - 36 - 540 = 0
(x - 6)^2 - 576 = 0
x - 6 = 24
or x -6 = -24
x = 30 or x = -18
w = 30 - 12 = 18
