Answer:

The answer is 145°

Step-by-step explanation:

Angle 3 and 4 make a right angle (90°) Subtract 55 from 90.

90-55=35

Angle 3 and Angle 1 are vertical angles, hence they have the same measurement.

Angle 1 is 35°

Angle 1 and 2 make a 180° angle. Subtract 35 from 180.

180-35=145

The measurement of angle 2 is 145°

Answer:

Step-by-step explanation:

∠5 + ∠4 = 90 + 55 = 145

∠2 = ∠5 + ∠4 (vertically opposite angles)

∴ ∠2 = 145

The other root of the polynomial is 5 + 7i.

Polynomial, a mathematical expression made comprised of numbers and variables arranged in specific patterns. Polynomials are sums of monomials of the form ax^n, where n (the degree) must be a whole number and a (the coefficient) can be any real number. The greatest degree monomial in a polynomial determines the polynomial's degree. Polynomials can be prime or factorable into products of primes, just like whole numbers. As long as each variable's power is a non negative integer, they can include any number of variables. They serve as the foundation for solving algebraic equations.

As per the given data:

One root of a polynomial is 5 - 7i

For finding the other root:

Consider the quadratic formula:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

From here, we can observe that imaginary roots will always occur in a pair.

So if one root is a + ib the other will be a - ib.

Similarly, for 5 - 7i the other root will be 5 + 7i.

Hence, the other root of the polynomial is 5 + 7i.

From the question, we have the following parameters that can be used in our computation:

Center = (0, 0).

Point = (6, 12), (8, 12) and (8, 8)

Scale factor = 3

A dilation with center (0, 0) and scale factor k multiplies the coordinates of a point by k.

So, to find the image of the point under the dilation with scale factor 3/2, we multiply each coordinate by 3/2:

Image = [(6, 12), (8, 12) and (8, 8)] * 3/2

Image = [(9, 18), (12, 18) and (12, 12)]

The value for k has to be taken, to ensure that the probability, that - when we take a distance measurement y in practice - this distance measurement lies inside the interval [x – ko, x + ko), equals 99% is  0.516.

To find the value of k that ensures that the probability that the distance measurement lies inside the interval [x – ko, x + ko) equals 99%, we can use the standard normal distribution table.

First, we need to find the z-score that corresponds to the 99% probability. This is found by looking at the standard normal distribution table and finding the z-score that corresponds to a cumulative probability of 0.995 (since the probability is split between both sides of the mean, we need to look for 0.995 instead of 0.99).

The z-score that corresponds to 0.995 is approximately 2.58.

Now, we can use the formula for the z-score to find the value of k:

z = (y - x)/o

Since we are looking for the value of k that corresponds to the interval [x – ko, x + ko), we can plug in the values for the z-score and the standard deviation:

2.58 = (x + ko - x)/0.2

Solving for k, we get:

k = 2.58 * 0.2

k = 0.516

Therefore, the value for k that ensures that the probability that the distance measurement lies inside the interval [x – ko, x + ko) equals 99% is 0.516.

The total area of the painting and frame is 112 in²

An equation is an expression that shows the relationship between two or more numbers and variables. Equations can either be linear, quadratic, cubic and so on depending on the degree.

Let x represent the length of the smaller edge.

One edge of a painting is 6 in. longer than the other edge. Hence:

Longer edge = x + 6

The painting has a 2-inch-wide frame.

Smaller edge length with frame = x + 2 + 2 = x + 4

Longer edge length with frame = (x + 6) + 2 + 2 = x + 10

Total area = (x + 4)(x + 10)

Total area = x² + 14x + 40

The longer side of the frame is 14 inches long, hence:

x + 10 = 14

x = 4 in

Total area = x² + 14x + 40 = 4² + 14(4) + 40 = 112 in²

The product AB is not equal to the product BA. This demonstrates the non-commutativity of matrix multiplication.

Matrix multiplication is non-commutative, which means that the product of two matrices can be different depending on the order in which they are multiplied. In other words, AB is not always equal to BA. Let's find the product of the given matrices A and B in both orders to demonstrate this.

First, let's find the AB Product:
AB = [[1,-4],[-2,4]] * [[-4,0],[4,3]]
= [(1 * -4) + (-4 * 4), (1 * 0) + (-4 * 3), (-2 * -4) + (4 * 4), (-2 * 0) + (4 * 3)]

The area of the circle to the nearest whole number is 79 square feet.

What is the diameter?

In geometry, the diameter of a circle is defined as the longest straight line segment that can be drawn between any two points on the circle, passing through the center of the circle. It is twice the length of the radius of the circle.

The formula for the area of a circle is A = πr^2, where r is the radius of the circle.

Given that the diameter of the circle is 10 feet, we can find the radius by dividing the diameter by 2:

radius = diameter / 2 = 10 ft / 2 = 5 ft

Now we can use the formula to find the area of the circle:

A = πr^2

= π(5 ft)^2

= 25π square feet

To get the answer to the nearest whole number, we can use the approximation π ≈ 3.14:

A ≈ 25 × 3.14

a. R = 1820 - 25t
b. R = 1820 - 25(7) = 1345 billion barrels
c. The world's oil reserves will be depleted when R = 0, so 25t = 1820, t = 72.8 years

a. The linear equation for the remaining oil reserves, R, in terms of t, the number of years since now, is R = 1820 - 25t. This equation represents the starting amount of oil reserves (1820 billion barrels) and subtracts the amount that is depleted each year (25 billion barrels) multiplied by the number of years that have passed (t).
b. Seven years from now, the oil reserves will be R = 1820 - 25(7) = 1820 - 175 = 1645 billion barrels.
c. To find when the world's oil reserves will be depleted, we need to solve for t when R = 0. So we have:

0 = 1820 - 25t
25t = 1820
t = 1820/25
t = 72.8

The general solution to the differential equation y''+4y=0 is y(x) = c₁ cos ₂x + c₂ sin ₂x and the value of β is 2.

To find the value of β, we substitute the general solution into the differential equation and solve for β. We start by finding the first and second derivatives of y(x):

y'(x) = -c₁β sin βx + c₂β cos βx

y''(x) = -c₁β² cos βx - c₂β² sin βx

Substituting these expressions into the differential equation, we get:

-c₁β² cos βx - c₂β² sin βx + 4(c₁ cos βx + c₂ sin βx) = 0

Simplifying this equation, we get:

(c₁β² + 4c₁) cos βx + (c₂β² + 4c₂) sin βx = 0

This equation must hold for all values of x, which means that the coefficients of cos βx and sin βx must both be zero. Therefore, we have the following system of equations:

c₁β² + 4c₁ = 0

c₂β² + 4c₂ = 0

We can solve for β by dividing the second equation by c₂ and substituting c₁ = -4β²/c₂ from the first equation:

β² = -4c₁/c₂ = 4

Since β>0, we take the positive square root of 4, which gives β=2.

We must locate the data set's middle value in order to get the median. As there are 20 data points in this instance, the median is calculated as the average of the 10th and 11th values, both of which are 2 hours. As a result, 2 hours is the median amount of exercise per day.

We must determine the difference between the data set's maximum and minimum values in order to determine the range. The ranges are 0 hours for the minimum and 5 hours for the highest. The range is therefore 5 - 0 = 5 hours.

Finding the difference between the third quartile (Q3) and the first quartile is necessary to calculate the interquartile range (IQR) (Q1). The data set can be divided into the lower half and the upper half because the median is 2 hours. 10 data points are present in the upper half and 10 data points are present in the lower half.

The median of the lower half of the data set must be located in order to determine Q1. The median is the average of the fifth and sixth values, both of which are one hour because there are ten data points in the lower half. Q1 is therefore 1 hour.

We must determine the median of the upper half of the data set in order to determine Q3. The median is the average of the fifth and sixth values, which are both 4 hours, as there are 10 data points in the upper half. Q3 is therefore 4 hours.

To show that the family of conics with the same focus x^2/a^2+C + y^2/b^2+C = 1 is its own orthogonal family of curves, we need to take the derivative of the equation and set it equal to -1/b^2, the slope of the orthogonal line.

First, we take the derivative of the equation with respect to x:

2x/a^2 = -2y/b^2 * dy/dx

Simplifying, we get:

dy/dx = -b^2*x/a^2*y

Now, we set this equal to -1/b^2:

-b^2*x/a^2*y = -1/b^2

Cross-multiplying and simplifying, we get:

x/a^2*y = 1/b^2

Finally, we can rearrange this equation to get:

y = b^2*x/a^2

This equation represents the orthogonal family of curves to the original family of conics. Since the original equation and the orthogonal equation are the same, we can conclude that the family of conics with the same focus x^2/a^2+C + y^2/b^2+C = 1 is its own orthogonal family of curves.
