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

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).

Step-by-step explanation:

You're welcome.

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

The formula holds true for matrices A and B.

The formula (A + B)^2 = A^2 + 2AB + B^2 holds true for all matrices A and B that are of the same size and can be added and multiplied. To prove this, we calculate the left-hand side and the right-hand side of the equation:

(A + B)^2 = (A + B)(A + B) = A^2 + AB + BA + B^2

Since AB = BA, we can simplify the equation to:

(A + B)^2 = A^2 + 2AB + B^2

So, the formula holds true for matrices A and B.

The complete question is shown in figure.

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

ΔS = S' - S

ΔS = 0.96S - S

ΔS = - 4%

The surface area of the pyramid is 3136 square inches.

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.

The base area B = 8 x 8 = 64 square inches.

The surface area of the pyramid,

= B + 12(P x L)

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

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°.

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.

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.

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). In other words, the graph of g(x) will be parallel to the graph of f(x) but shifted upward by 13 units.

The 5th term of the geometric sequence described by an = 5(1.5)-1 is 6.5

Geometric progression,  which is also called geometric sequence, is defined as a sequence with non-zero numbers where all of the terms after the first is determined by multiplying the previous one by a fixed, non-zero number that is termed the common ratio.

The general formula for a geometric sequence is given as;

an = ar^n-1

From the information given, we have that the nth term of the geometric sequence is expressed with the equation;

an = 5(1.5)-1

expand the bracket

an = 7.5 - 1

Now, subtract the value, we get;

an = 6.5

The result of the definite integral by substitution is 214440.6.

In this problem we find the case of a definite integral, that is, an integral with definite limits, that must be simplified by algebraic substitution to be solved quicker. First, write the substitution formula and its derivative:

u = 6 · x - 7

du = 6 dx

f(u) = u⁴

Second, define the new limits of the definite integral:

a = 6 · 2 - 7

a = 5

b = 6 · 5 - 7

b = 23

Third, simplify the integral by means of the substitution formula:

[tex]\frac {1}{6}\int\limits^{23}_{5} {u^{4}} \, du[/tex]

Fourth, integrate the expression:

[tex]I = \frac{1}{30} \cdot u^{5}\left|_{5}^{23}[/tex]
