The altitude of the hill whose top rises 64 feet above checkpoint -213, is 277 feet above sea level.

The altitude refers to the vertical distance or height of an object or point in relation to sea level (true altitude) or ground level (absolute altitude).

The altitude of a hill refers to its height measured from the ground level or the sea level, as the case may be.

In this situation, we can compute the altitude of the hill as the difference between the rise of the hill or mountain above the checkpoint and the given checkpoint.

The rise of the top of a hill = 64 feet

Given checkpoint = -213

The altitude of the hill = 277 feet [64 - (-213)]

Thus, the position or altitude of the hilltop in relation to the ground or sea level is 277 feet.

Sherree's score on her 12th game is 86.67 in her golf game using equation.

A function is a procedure or a relation that links each element of a non-empty set A, at least one element of another non-empty set B, to another element of the first non-empty set A. In mathematics, a relation f between two sets, A and B, is referred to as the function's domain and co-domain.

Each element of X receives precisely one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

In order to have ordered pairs of the kind, relations and functions provide a mapping between two sets (Inputs and Outputs) (Input, Output). In algebra, relationship and function are crucial ideas. They are commonly employed in both real life and mathematics.

At games =2 score was 120

At games = 8 score was 100

so the equation is

y - 2 = (8-2)/(100-120) *(x-120)

⇒ (y-2)*(-20) = 6(x - 120)

⇒ -20y + 40 = 6x -720

⇒ 6x + 20y = 760

⇒ 3x + 10 y = 380

So, for y = 12

3x + 12*10 = 380

⇒ 3x +120 = 380

⇒ x = 260/3 = 86.67

Answer:

z = -8/3 - 5i

Step-by-step explanation:

Sorry, I don't know what a ti-84 calculator is.

But, I can solve this question normally.

Let the real part of z be x and the imaginary part be y.

z = x + iy

|z| = √(x²+y²)

z + |z| = x + iy + √(x²+y²) = 3 - 5i

Now, y has to be -5 as |z| is a real number so the only component affecting i is y. Therefore, y = -5.

Now, lets figure out the real part.

Cancel out imaginary part.

x + √(x² + 25) = 3

3 - x = √(x² + 25)

squaring on both sides,

9 + x² - 6x = x² + 25

6x = -16

x = -8/3

Hence the required complex number is -8/3 - 5i

When the number of blue frogs increased by 60% and the number of green frogs decreased by 60%, the percentage of the overall increase is solved to be 60%

Assuming the number of blue frogs and the number of green frogs are equal and = y

Then the total number of frogs = y + y = 2y

Increasing the percentage of each by 60%, the factor for percentage increase by 60% is 1.6

hence 1.6y + 1.6y = 3.2y

percentage change

= change in price / original price * 100

= (3.2y - 2y) / 2y * 100

= 1.2y / 2y * 100

Step-by-step explanation:

To start off, let's find the y-intercept, which is when x=0

So, when x=0,

[tex]y=\frac{3}{4}(0)+5[/tex], which is y=5.

So we can put a point on (0, 5)

From there, since the slope is 3/4. We can go up 3 and right 4 to plot a point there, you can also do down 3 and down 4 from the y-intercept point, then keep going either, up 3 and right 4 or down 3 and left 4, which should give you a diagonal line that looks something like;

Table F shows a proportional relationship and its points are plotted in the graph shown in the image attached below.

In Mathematics, the graph of any proportional relationship is represented by a straight line with the data points passing through the origin (0, 0) because as the values on the x-axis increases or decreases, the values on the y-axis increases or decreases simultaneously.

Mathematically, a proportional relationship can be represented or modeled by the following linear equation:

y = kx

Where:

Next, we would determine the constant of proportionality (k) for the data points on this graph as follows:

Constant of proportionality, k = y/x

Constant of proportionality, k = 2/1 = 4/2 = 8/4 = 10/2

Constant of proportionality, k = 2.

Therefore, the linear equation for this proportional relationship can be correctly written as follows:

Answer:

(a) The central 95% of IQ scores in a standardized test would be found in the interval from 85 to 115. This is because a normal distribution is symmetric around the mean, and 95% of the data falls within two standard deviations of the mean. So, the interval would be mean - 2standard deviation to mean + 2standard deviation i.e. 100 - 215 to 100 + 215 = 85 to 115

(b) About 2.5% of people should have IQ scores above 115. This is because the IQ scores follow a normal distribution and IQ scores above 115 are considered to be in the top 2.5% of the distribution.

(c) About 16% of people should have IQ scores between 70 and 85. This is because the IQ scores follow a normal distribution, and IQ scores between 70 and 85 fall within one standard deviation of the mean (85 is one standard deviation below the mean and 70 is one standard deviation below that)

(d) About 0.1% of people should have IQ scores above 130. This is because IQ scores above 130 are considered to be in the top 0.1% of the distribution.

What is the system of equations?

System of equations, also known as simultaneous equations, Two or more equations to be solved together in algebra (i.e., the solution must satisfy all the equations in the system). The number of equations must equal the number of unknowns for a system to have a unique solution.

Given that a worker earns $16.10 per hour with 1 year of experience.

The other worker earns $21.30 per hour with 3 years of experience.

The model that represents the wages of a worker is

y = ax + b

Where x is the number of years of experience, and y is total wages.

Now putting x =1 and y = 16.10 in y = ax + b:

16.10 = a + b .....(i)

Now putting x =3 and y = 21.30 in y = ax + b:

21.30 = 3a + b .....(ii)

Subtract equation (ii) from equation (i)

3a + b =21.30

a + b = 16.10

(-)  (-)    (-)

__________

2a = 5.2

a = 2.6

Putting a = 2.6 in equation (i)

16.10 = 2.6 + b

b = 16.10 - 2.60

b = 13.5

The model is y = 2.6x + 13.5

A worker's starting wage is $13.5 at this job.

Putting x = 7  in y = 2.6x + 13.5:

y = 2.6×7 + 13.5

The total surface area of the rectangular prism is 160 inches².

Since the base of the rectangular prism is a square, we know that the edge length of the base is the square root of the area of the base. The area of the base is 16 square inches (since it can be completely covered by 16 squares with edge length of 1 inch), so the edge length of the base is 4 inches.

Since the height of the prism is twice the edge length of the base, the height of the prism is 8 inches.

The total surface area of a rectangular prism is given by the formula:

2lw + 2lh + 2wh

Where l is the length, w is the width and h is the height

So, the total surface area of the rectangular prism is:

The shape of the ABCD is a rhombus. The diagonals are not equal to each other.

What is the 2-dimensional shape?

A two-dimensional shape with horizontal and vertical axes is known as a 2d shape (x-axis and y-axis). Two-dimensional shapes have only length and width. There is no thickness or height to these shapes.

Given the vertices of ABCD are  A(-3,0), B (1,5), C(-3,10) and D(-7,5).

The formula distance between points (x₁, y₁) and (x₂, y₂) is √[(x₂ - x₁)² + (y₂ - y₁)²].

The distance between A and B is √[(1 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between B and C is √[(-3 - 1)²+(10 - 5)²] = √(4²+5²) = 6.4

The distance between C and D is √[(-7 - (-3))²+(5 - 10)²] = √(4²+5²) = 6.4

The distance between A and D is √[(-7 - (-3))²+(5 - 0)²] = √(4²+5²) = 6.4

The distance between A and C is √[(-3 - (-3))²+(10 - 0)²] = √(10²) = 10

The distance between B and D is √[(-7 - 1)²+(5 - 5)²] = √(8²) = 8

The slope of a line passes through the points (x₁, y₁) and (x₂, y₂) is (y₂ - y₁)/(x₂ - x₁).

The slope of AB is (5-0)/(1-(-3))=5/4

The slope of BC is (10-5)/(-3-1)=-5/4

The slope of CD is (5-10)/(-7-(-3))=5/4

The slope of AD is (5-0)/(-7-(-3))=-5/4

The number of vertices of the quadrilateral is 4.
