Okay so this is for my portfolio. I have two figures; a rectangular prism (think cereal box) and a cylinder. Is it possible for the cylinder to have a larger VOLUME than the prism, but a smaller measurement of cubic inches?? (Please say yes )

Answers

Step-by-step explanation:

No, it is not possible. Cubic inches are a measurement of volume. If the cylinder has a larger volume, then it also has more cubic inches.

Answer:

no TWT

Step-by-step explanation:

Because these solids have the same height and the same cross-sectional areas at every level, the solids have the same volume due to Cavalieri's principle. The volume of the prism is: V = A B a s e ⋅ h = π r 2 h Therefore, the volume of the cylinder is: V = π r 2 h This should make sense because a cylinder is essentially a circular prism.

Answers

The difference in total cost between the two mortgages is $168,852. The Option A is closest.

What is the difference in the total cost?

To get total cost of the adjustable-rate mortgage, we have to find total payments for each period and add them up.

Using the monthly payments, we get:

Total payments for years 1-5:

= $2,506.43 x 12 x 5

= $150,385.80

Total payments for years 6-15:

= $3,059.46 x 12 x 10

= $367,135.20

Total payments for years 16-25:

= $3,464.78 x 12 x 10

= $415,773.60

Total payments for years 26-30:

= $3,630.65 x 12 x 5

= $217,839.00

Total cost of adjustable-rate mortgage: $1,151,133.60

The total cost of the fixed-rate mortgage is computed as follows. The Total payments for 30 years is:

= Monthly payment x Number of payments

= $2,728.56 x 12 x 30

= $982,281.60

The difference in total cost is:

= $1,151,133.60 - $982,281.60

= $168,852.00.

Dr. Salaam orders 39 grams of marijuana for a patient. Each bud is about 0.07 grams of marijuana.

How many buds will each patient need and If the dispensary charges $530 an ounce for the strain the patient likes, how much will the patient have to pay in total? (28.4 grams = 1 ounce)

Answers

The patient will have to pay approximately $727.74 in total.

How to solve for the  dispensary charges

Total grams of marijuana: 39 grams

Weight of each bud: 0.07 grams

Number of buds = Total grams of marijuana / Weight of each bud

Number of buds = 39 / 0.07 ≈ 557.14

Since the patient can't purchase a fraction of a bud, they will need 558 buds (rounding up).

Now, let's calculate the total cost.

Dispensary cost: $530 per ounce (28.4 grams)

First, we need to find the cost per gram:

Cost per gram = $530 / 28.4 ≈ $18.66

Total grams of marijuana: 39 grams

Total cost = Cost per gram * Total grams of marijuana

Total cost = $18.66 * 39 ≈ $727.74

The patient will have to pay approximately $727.74 in total.

An economy's consumer price index (CPI) is described by the function f(t)=-0.1t^3+3t^2+500 where t=0 corresponds to the year 1995. Find the point of inflection of the function.

Answers

Answer: t=10, or in 2005

Explanation: the point of inflection refers to when a function switches concavity (i.e. up or down). If the second derivative of f is positive, the graph is concave up, and if it is negative, the graph is concave down. This means that the graph switches concavity when the second derivative equals zero.

To find the second derivative (f’’(t)), we shall first find f’(t), or the first derivative. Because each term is separated by addition/subtraction, we can take the derivative of each term separately. Using the power rule, ((d/dx)(-0.1t^3)) = -0.1(3)(t)^(3-1)= -0.3t^2. For d/dx of 3t^2, use the power rule again: 3(2)t^(2-1) = 6t. The derivative of 500 is 0 because it is a constant. f’(t) = -0.3t^2 + 6t.

Now we shall do this process again to find the second derivative. For the first term, d/dx of -0.3t^2 = -0.3(2)t^(2-1) = -0.6t. For 6t, d/dx equals 6(1)t^(1-1) = 6. f”(t) = -0.6t + 6

Now that we have the second derivative, we set it equal to zero and solve for t. 0 = -0.6t + 6, -6 = -0.6t, t = 10. Because t = 10 years, the point of inflection occurs in 1995 + 10 = 2005.

The difference of a number and 4/3 is 11/3. What is the number?

Answers

Answer:

n = 5

Step-by-step explanation:

Let n represent the unknown the numberSince we know the difference of n and 4/3 is 11/3, we can use the following equation to solve for n:  n - 4/3 = 11/3

Step 1:  Multiply both sides by 3 (i.e., the least common multiple of 3) to clear the fractions:

3(n - 4/3 = 11/3)

3n -12/3 = 33/3

3n - 4 = 11

Step 2:  Add 4 to both sides:

(3n - 4 = 11) + 4

3n = 15

Step 3:  Divide both sides by 3 to solve for n:

(3n = 15) / 3

n = 5

What is the area of DEF? D to F is 7.65, d to e is 2.12 and e to f is 6

Answers

To find the area of triangle DEF, we can use Heron's formula, which states that the area of a triangle with sides of lengths a, b, and c is:

A = sqrt(s(s-a)(s-b)(s-c))

where s is the semiperimeter of the triangle, defined as:

s = (a + b + c)/2

In this case, we have:

a = DE = 2.12
b = EF = 6
c = DF = 7.65

The semiperimeter is:

s = (a + b + c)/2 = (2.12 + 6 + 7.65)/2 = 7.885

Therefore, the area of triangle DEF is:

A = sqrt(s(s-a)(s-b)(s-c)) = sqrt(7.885(7.885-2.12)(7.885-6)(7.885-7.65)) = 9.63

The area of triangle DEF is approximately 9.63 square units.

The function is transformed and it is a vertical stretch with a factor of 100 and a translation 5 units down

Given data ,

Let the transformed function be represented as f' ( x )

Now , The pace of filling a 100-gallon fish tank is x gallons per minute. The tank has been filling for five minutes already.

The parent function's graph is f (x) = x.

Consequently, the function's graph is provided as

f ( x ) = ( 100/x ) - 5

The graph is now 100 times longer vertically, giving us f (x) = 100/x.

By translating by 5 units down, we obtain f (x) = (100/x) - 5.

Hence , it is a translation of 5 units down and a vertical stretch of 100.

Answers

The area of the small sector is (131/360) * pi * 3^2 = 3.422 cm^2 (rounded to 3 decimal places).

To find the area of the large sector, we need to subtract the area of triangle ADB from the area of the circle sector ACB. We can use the Law of Cosines to find the length of segment AD:

AD^2 = AB^2 + BD^2 - 2 * AB * BD * cos(ACB)
AD^2 = 3^2 + 2^2 - 2 * 3 * 2 * cos(131)
AD^2 = 13 - 12cos(131)
AD = sqrt(13 - 12cos(131))

The area of triangle ADB is (1/2) * AB * AD * sin(DAB) = (1/2) * 3 * sqrt(13 - 12cos(131)) * sin(49) = 1.786 cm^2 (rounded to 3 decimal places).

The area of the large sector is pi * 3^2 - 1.786 = 23.556 cm^2 (rounded to 3 decimal places).

Therefore, the area of the small sector is 3.422 cm^2 and the area of the large sector is 23.556 cm^2.

In a class of 30 students, 12 have a cat and 19 have a dog. There are 6 students who
do not have a cat or a dog. What is the probability that a student chosen randomly
from the class has a dog?

Answers

Answer:

P(dog) = 12/30 = 0.4 or 40%

Step-by-step explanation:

We can use the formula for probability:

P(dog) = number of students with a dog / total number of students

To find the number of students with a dog, we can use the fact that 19 students have a dog and 6 students have neither a cat nor a dog:

number of students with a dog = total number of students - number of students with no pets - number of students with only a cat

number of students with a dog = 30 - 6 - 12 = 12

So the probability that a student chosen randomly from the class has a dog is:

P(dog) = 12/30 = 0.4 or 40%

Answers

Answer:

Step-by-step explanation:

The correct statement about the given equations is: "The equations are dependent because the lines are the same line."

In the equation y = 2x + 5, the slope is 2, which means the line has a positive slope and is upward sloping.

The y-intercept is 5, indicating that the line intersects the y-axis at the point (0, 5).

The equation y = -2x + 5 is equivalent to y = 2(-x) + 5, which has the same form as the first equation but with a negative slope.

However, the equations are still dependent because when you simplify the second equation, you obtain the first equation.

These two equations represent the same line with a different slope. Therefore, they are dependent, and any point that satisfies one equation will satisfy the other equation as well.
