Answer:  D. 58 degree

Step-by-step explanation:

A triangle has a total of 180 degrees

92 + 30 = 122 degree

180 - 122 = 58 degree

So, the answer is D. 58 degree

The equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.

An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.

Given:

Point (6,-4),

2x - y = 5,

Calculate the slope as the line is perpendicular to line 2x - y = 5

m = 2

The slope of the line perpendicular, m = - 1 / 5

Calculate the equation of the line as shown below,

[tex]y - (-4) = - 1 / 5 (x - 6)[/tex]

5 (y + 4) = -x + 6

5y + 20 = -x + 6

5y + x = -14

Therefore, the equation of the line that passes through the point (6,-4) and is perpendicular to the line 2x - y = 5 is 5y + x = -14.

The height of the building is 44 meters

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

Height of the tree = 22 m

From the question, we understand that

Scale of the diagram = 2

This means that

Height of the building = Height of the tree * Scale of the diagram

Substitute the known values in the above equation, so, we have the following representation

Height of the building = 22 m * 2

Evaluate

Height of the building = 44 m

Step-by-step explanation:

Based on the given conditions, formulate: 32 / 4 Cross out the common factor

Answer:

Below

Step-by-step explanation:

10 % OFF means you pay 90% of price

x = original price

Store A :   5% off    means   price is .95x

                    then another 10% off would mean  .9 * (.95x)

                        then another 10% off would mean  .9 * ( .9 *(.95x)

                               this equals .7695 x

Store B 25% off means you pay 75%  

  price is then .75x

price of      .75x at store B is < than .7695 x at store A  

    so B has greater discount

Answer:

Step-by-step explanation: To compare the discounts offered by Store A and Store B, we need to calculate the final price of the item after all discounts have been applied.

For Store A, the successive discounts of 5%, 10%, and 10% can be applied as follows:

The initial price of the item is reduced by 5%, resulting in a price of 0.95 * Price.

The price from step 1 is reduced by an additional 10%, resulting in a price of 0.9 * (0.95 * Price) = 0.855 * Price.

The price from step 2 is reduced by an additional 10%, resulting in a price of 0.9 * (0.855 * Price) = 0.7695 * Price.

For Store B, the single discount of 25% can be applied as follows:

The initial price of the item is reduced by 25%, resulting in a price of 0.75 * Price.

Comparing the final prices of the item at Store A and Store B, we can see that Store B offers a greater discount. The final price of the item at Store A is 0.7695 * Price, while the final price at Store B is 0.75 * Price. Since 0.75 is less than 0.7695, the final price at Store B is lower.

Therefore, Store B offers a greater discount on the item.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Answer:

the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).

Step-by-step explanation:

Correctly me if im wrong. To rationalize the denominator of the fraction 1/(5^(1/2)-2), we can use the conjugate of the denominator. The conjugate of a+b is a-b, so the conjugate of 5^(1/2)-2 is 5^(1/2)+2. We can then multiply the numerator and denominator of the fraction by the conjugate to obtain:

1/(5^(1/2)-2) * (5^(1/2)+2)/(5^(1/2)+2)

= (1*(5^(1/2)+2)) / ((5^(1/2)-2)*(5^(1/2)+2))

= (5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)

Notice that we can further simplify this expression by substituting 5^(1/2) with x and expanding the denominator:

(5^(1/2)+2) / (5^2 - 2*5^(1/2) - 4)

= (x+2) / (x^2 - 2x - 4)

= (x+2) / (x-2)(x+2)

The denominator of this expression can be further simplified by factoring out x-2, which gives us:

(x+2) / (x-2)(x+2)

= (x+2) / (x-2)(x-2 + 4)

= (x+2) / (x-2)(x^2 - 2x + 4 - 4)

= (x+2) / (x-2)(x^2 - 2x)

= (x+2) / (x-2)((x-1)(x+1))
Finally, we can use the fact that x-1 and x+1 are factors of x^2-2x, which means that we can factor out x-1 and x+1 from the denominator to obtain the fully simplified expression:
(x+2) / (x-2)(x^2 - 2x)

= (x+2) / (x-2)(x-1)(x+1)

= (x+2) / ((x-2)(x-1)(x+1))

Therefore, the rationalized form of the denominator 1/(5^(1/2)-2) is (x+2)/((x-2)(x-1)(x+1)).

A  conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

The likelihood that any two events will occur is equal to the sum of the probabilities of each event separately, less the probability that the two occurrences will meet. However, if two occurrences are incompatible with one another, then there is a zero probability of the two events intersecting, therefore the likelihood that either one or the other will occur is equal to the sum of the two individual probabilities.

To calculate conditional probability, use the following formula:

p( b | a ) = p( a ∩ b )/ p(a)

It is known that if two events A and B are independent, then p(a ∩ b) = p (a) . p(b)

So, p(b | a) = [p (a) . p(b)]/p(a) = p(b)

Thus, it is concluded that a conditional probability p(b | a) is equal to its marginal probability p(b) if A and B are independent.

Range (interval notation): [1,4)

Domain (inequality notation): -4 ≤ x < 4

Range (inequality notation): 1 ≤ x < 4

The collection of values that can be put into a function's domain are called its parameters. The x values for a function like f(x) are contained in this collection (x). The collection of values that a function can take on is known as its range. Following the putting of the x value, the function outputs this sequence of values.

Utilizing graphs is a useful tool for determining the scope and range of functions. A graph's domain is the entire set of input values shown on the x-axis since the term "domain" refers to the set of potential input values. The various output values are displayed on the y-axis and make up the range.

Domain (interval notation) : [-4,4)
