Two quantities x and y vary inversely, y=4 when x=7. Identify the value of constant variation, a, for the function.
y= ___/x
I will mark you brainliest!!

Answers

Answer 1

Answer:

28

Step-by-step explanation:

The constant variation, a, is equal to the product of x and y when they are both known. In this case, when x = 7 and y = 4, the constant variation is 4 * 7 = 28. So, the equation for the inverse variation is y = 28 / x.

What is pyramid?

A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base. The bases are joined to the peak to create a pyramid. The lateral face is a triangle face formed by the connection of each edge of the base to the apex.

Given:

Each side of the base of a square pyramid measures 8 inches.

The height of each lateral face of the pyramid is also 8 inches.

The perimeter of the base P is 32 inches.

An oil exploration firm is to drill 10 wells, each in different locations. Each well has a probability of 0.1 of producing oil. It will cost the firm $60,000 to drill each well. A successful well will bring in $1 million, taking into account the cost of drilling.

1. What is the probability that the firm will lose money on the ten wells?

2. What is the probability that the firm will gain $1.5 or more from the ten wells?

Answers

The probability the firm will lose money from 10 wells is 0.99 and the probability the firm will gain 1.5 million from the ten wells is  1 minus the CDF of 4 successful wells.

What is the probability the firm will lose or gain money

1.

The expected profit from each well is $1 million - $60,000 = $940,000. The expected profit from all ten wells is $940,000 * 10 = $9,400,000. The probability of losing money on all ten wells is 1 - (0.1)^10 = 0.99

2.

To calculate the probability of gaining $1.5 million or more, we can use the cumulative distribution function (CDF) of the binomial distribution, which models the number of successful wells out of ten. The CDF gives the probability of getting a certain number of successful wells or fewer. To get the probability of getting more than a certain number of successful wells, we subtract the CDF of that number from 1. To get the probability of getting 2 or more successful wells, we subtract the CDF of 1 from 1, and so on. To get the probability of getting 5 or more successful wells, we subtract the CDF of 4 from 1, and so on. To get the probability of getting $1.5 million or more, we need to find the probability of getting 5 or more successful wells, since 5 wells at $1 million each give $5 million. The CDF of 4 successful wells can be found using statistical software or by using tables or approximations. The final answer is 1 minus the CDF of 4 successful wells.

40000=6(6)^x What is the value of X

Answers

Step-by-step explanation:

Given:

Present value =₹ 40000

Interest rate =6% per annum

Time =6 months

To find the amount we have the formula,

Amount (A)=P(1+(r/100))n

where P is present value, r is rate of interest, n is time in years

Now substituting the values in above formula we get,

∴A=40000(1+(6/4)/100) ²

⇒A=40000(1+3/200)²

⇒A=40000(203/200)²

⇒A=40000(203/200) ²

⇒A=203×203

⇒A=₹ 41209

∴ Compound interest =A–P

=41209–40000=₹ 1209

Step-by-step explanation:

The surface area of a square pyramid can be calculated by summing up the area of its base and four lateral faces.

The base area of the square pyramid is 8 x 8 = 64 in².

The area of each lateral face is a triangle with base 8 in and height 8 in, so its area is 1/2 x 8 x 8 = 32 in².

So the total surface area of the pyramid is 64 + 4 x 32 = 192 in².

Answers

The solution for the system of equations is negative one fourth comma three fourths.

What are Linear Equations?

Linear equations are equation involving one or more expressions including variables and constants and the variables are having no exponents or the exponent of the variable is 1.

Slope intercept form of a line is y = mx + c, where m is the slope and c is the y intercept.

Given two lines on a graph.

Let y = m₁x + c₁ and y = m₂x + c₂ are the equations of two lines.

One line passes through (0, 1) and (1, 2).

m₁ = (2 - 1) / (1 - 0) = 1

Substituting m₁ = 1 and a point (x, y) = (0, 1) in y = m₁x + c₁,

1 = c₁

Equation of one line is y = x + 1.

Other line passes through (0, 0) and (1, -3).

m₂ = (-3 - 0) / (1 - 0) = -3

Substituting m₂ = 1 and a point (x, y) = (0, 0) in y = m₂x + c₂,

0 = c₂

Equation of second line is y = -3x

Solving both the equations y = x + 1 and y = -3x,

-3x = x + 1

-4x = 1

x = -1/4

y = -3x = 3/4

Solution is (-1/4, 3/4).

Hence the solution of the system of equations is the point (-1/4, 3/4).

Answers

Based on the proportionate equation of the selling price (S), cost price (C), and profit (P), the change in S caused by decrease of C and increase of P is decrease by 4%

Based on the given information, we know that:

S ∝ √C --> S directly varies as the square root of C

S ∝ 1/P³ --> S inversely as the cube of P

We can combine both relationships to make a proportionate equation:

S = √C / P³

We know from the case that:

ΔC = - 2%

ΔP = 1%

Then:

C' = C + ΔC

C' = C + (-0.02)P

C' = 0.98C

P' = P + ΔP

P' = P + (0.01)P

P' = 1.01P

S' = √C' / P'³

S' = √(0.98C) / (1.01P)³

S' = 0.96 √C/P³

S' = 0.96S

The graph of the function g(x) = 1/x + 13 is a transformation of the graph of f(x) = 1/x. The transformation that has been applied is a vertical shift of 13 units upward. This means that every point on the graph of f(x) has been moved upward by 13 units along the y-axis, resulting in the new graph of g(x).

The sum of the angles of the triangle below are angle A = 34.91°, angle B = 86.41°, and angle C = 58.68°.

What is triangle sum theorem?

According to the triangle sum theorem, a triangle's internal angles can be added up to 180 degrees. The triangle sum theorem, often referred to as the angle sum theorem of the triangle, states that the total of the measures of a triangle's internal angles in a Euclidean space adds up to 180 degrees, whether the triangle is acute, obtuse, or right.

Let a = 8, b = 14 and c = 12 for the given triangle.

Then,

cos (A) = (b² + c² − a²) / 2bc

cos (A) = (14² + 12² - 8²)/ (2)(14)(12)

cos (A) = (196 + 144 - 64)/ 336

cos (A) = 0.82

A = cos⁻¹ (0.82)

A = 34.91°

Similarly, for angle B.

Cos (B) = (c² + a² − b²)/2ca

Cos (B) = (12² + 8² - 14²)/ (2)(12)(8)

A = cos⁻¹ (0.0625)

B = 86.41°

The sum of all the angles of a triangle is 180:

A + B + C = 180°

34.91° + 86.41° + C = 180°

C = 58.68°

Hence, the sum of the angles of the triangle below are angle A = 34.91°, angle B = 86.41°, and angle C = 58.68°.
