A hyperbola is an open curve with two branches, the intersection of a plane with both halves of a double cone.

To graph the hyperbola y^2/16 - x^2/9 = 1 and determine its type of transverse axis, follow these steps:

Step 1: Identify the center of the hyperbola.
The center of the hyperbola is at the origin, (0, 0), since there are no shifts in the equation.

Step 2: Determine the orientation of the hyperbola.
The positive term in the equation is associated with y^2, so the hyperbola will be vertically oriented. This means that the transverse axis will be vertical.

Step 3: Calculate the distance from the center to the vertices.
The distance to the vertices is given by the square root of the denominator under the y^2 term. In this case, it is √16 = 4. The vertices are then at (0, ±4).

Step 4: Calculate the distance from the center to the co-vertices.
The distance to the co-vertices is given by the square root of the denominator under the x^2 term. In this case, it is √9 = 3. The co-vertices are at (±3, 0).

Step 5: Sketch the hyperbola.
Plot the center, vertices, and co-vertices. Draw the asymptotes through the center and the corners of the rectangle formed by the vertices and co-vertices. Finally, draw the hyperbola opening vertically along the transverse axis.

In conclusion, the hyperbola y^2/16 - x^2/9 = 1 has a vertical transverse axis.

The sum of the areas of the non-hexagonal faces of the prism is 9 square feet.

A right hexagonal prism has only one type of non-hexagonal faces: six rectangular faces.

Since the base of the hexagon is a regular hexagon, the length of each side of the base is 6 inches. Using the formula for the perimeter of a regular hexagon, P = 6*s

we can find that the perimeter of the hexagon is,

Perimeter = 6*6 inches = 36 inches = 36/12 feet = 3 feet

The total area of six rectangular faces is found by multiplying the length of the perimeter by the height of the prism.

Area= Perimeter* height

=3 feet * 3 feet

= 9 sqft

Consider the same figure as given above. It is observed that DP/PE = DQ/QF and also in the triangle DEF, the line PQ is parallel to the line EF.

So, ∠P = ∠E and ∠Q = ∠F.

Hence, we can write: DP/DE = DQ/DF= PQ/EF.

The above expression is written as

DP/DE = DQ/DF=BC/EF.

It means that PQ = BC.

Hence, the triangle ABC is congruent to the triangle DPQ.

(i.e) ∆ ABC ≅ ∆ DPQ.

Thus, by using the AAA criterion for similarity of the triangle, we can say that

∠A = ∠D, ∠B = ∠E and ∠C = ∠F.

The ratio of baking powder to flour is 1/192 teaspoon of baking powder for every teaspoon of flour.

The amount of baking powder per unit of flour is the unit rate for baking powder and flour. The amount of flour in this situation equals 1 2/3 cups. We must change the baking powder measurement to the same unit as the flour measurement in order to calculate the unit rate.

For every 1 2/3 cups of flour, 1/4 teaspoon of baking powder should be used as follows:

1/4 teaspoon / (1 2/3 cups)

By changing the numerator and denominator of the fraction on the right side to a standard unit, such as teaspoons, we may make it simpler. 1 2/3 cups equal 48 teaspoons, so:

1/4 teaspoon / (1 2/3 cups) = 1/4 teaspoon / (48 teaspoons)

The ratio of baking powder to teaspoons is as follows:

1/4 teaspoon / (48 teaspoons) = 1/192 teaspoon per teaspoon

So The ratio of baking powder to flour is 1/192 teaspoon of baking powder for every teaspoon of flour.

The completed statements with regards to the compound interest of the amount in the account are;

If the account has a 5% interest rate and is compounded monthly, you have $101.655 million money after 2 years

If the account has a 5% interest rate compounded continuously, you would have $106.096 million money after 2 years

Compound interest is the interest calculated based on the initial amount and the accumulated interests accrued from the periods before the present.

The compound interest formula indicates that we get;

\(A = P\cdot (1 + \frac{r}{n}) ^{n\cdot t}\)

Where;

P = The principal amount invested = $92 million

r = The interest rate = 5% monthly

n = The number of times the interest is compounded per annum = 12

t = The number of years = 2 years

Therefore; \(A = 92\cdot (1 + \frac{0.05}{12}) ^{12\times 2}\approx 101.655\)

The amount in the account after 2 years is therefore about $101.655 million

The formula for the amount in the account if the principal is compounded continuously, we get;

A = \(P\cdot e^{(r\cdot t)}\)

Therefore, we get;

\(A = 96 \times e^{0.05 \times 2} \approx 106.096\)

The amount in the account after 2 years, compounded continuously therefore, is about $106.096 million

Therefore , the solution to the given problem of circle comes out to be  

572 yard^2.

Each point in the plane that is a certain distance from some other point forms a circle (center). Thus, it is an curve composed of spots that are spaced apart from one another in the plane. Additionally, at every angle, it is axis of rotation symmetric about the center. The closed, two-dimensional plane of a circle has every pair of points uniformly separated from the "center." With tracing a path through the circle, one can create a line of circular symmetry. Additionally, at every angle, it is radially symmetric about the center.

Given that April has 30 days, Luke used, on average, 20.05 kilowatt-hours of electricity per day during April.

The average is the mean value obtained by dividing the total value of a data set by the number of items.

In this situation, we can divide the total electric bill for April by 30 to obtain the average daily charge.

In addition, we can divide the average charge per day by the cost per kilowatt-hour to obtain the number of kilowatt-hours used per day.

The total electric bill for April = $84.21

The charge per kilowatt-hour (kWh) = $0.14

The number of days in April = 30

The bill per day = $2.807 ($84.21/30)

The kilowatt-hours per day = 20.05 kWh ($2.807/$0.14)

Thus, Luke used an average of 20.05 kilowatt-hours per day in April.

We want to write an equation that shows the relationship.

30% of 105 is x.

First, remember that if we take a percentage X of a number N, the expression is:

N*(X/100%).

In this case we are taking the 30% of 105, then the expression is:

105*(30%/100%)

A total of 30 golf balls are there in the bag that weighs 1110 grams.

A total of 69 golf balls weights 2553 grams in a bag.

It is asked that how much golf balls does make 1110 grams of weight.

Let us say that the weight of one ball is X.

So, Using unitary method,

We can write,

69 times mass of one golf ball = 2553 grams.

69X = 2553

X = 2553/69

X = 37 grams.

Hence, the weight of one ball is 37 grams.

Now, let us say that Y balls weights 1110 grams,

So, we can write,

Y time weight of one ball = 1110

37Y = 1110

Y = 1110/37

Y = 30.

Hence, 30 golf balls will weight 1110 grams.

Answer:

x= 8

Step-by-step explanation:

step: Substitute−3x+33 for y in x+y=17:

x+y=17

x+−3x+33=17

−2x+33=17(Simplify both sides of the equation)

−2x+33+−33=17+−33(Add -33 to both sides)

−2x=−16

If 3x + y = 33 and x +y = 17, then the value of x is 8. See the analysis below.

To find the value of x, we can solve the given system of equations  -

Equation 1  -  3x + y = 33

Equation 2  -  x + y = 17

We can use the method of substitution or elimination to solve the system. Here, we will use the method of elimination.

Multiplying Equation 2 by 3, we get  -

3(x + y) = 3(17)

3x + 3y = 51

Now we can subtract Equation 1 from the modified Equation 2  -

(3x + 3y) - (3x + y) = 51 - 33

2y = 18

Dividing both sides of the equation by 2  -

2y/2 = 18/2

y = 9

Substituting the value of y into Equation 2  -

x + 9 = 17

x = 17 - 9

x = 8

Therefore, the value of x is 8.

Answer:

1684.8 cubic units

Step-by-step explanation:

In oblique cylinder the height (altitude) is measured from the opposite base to the base of the cylinder, but it lies outside. We can find the height using Pythagoras theorem.

       h + 7² = 13²

              h²= 169 - 49

              h² = 120

               h = √120

                h = 10.95 units

radius = r = 7 units

\(\boxed{\text{\bf Volume of oblique cylinder = $\bf\pi r^2h$} }\)

                                                    = 3.14 * 7 * 7 * 10.95

                                                    = 1684.8 cubic units
