The system of inequatilies that is represented in the graph is:

y ≥ –x² – x + 1

y > 2x² + 3

We can confirm this statement since the first equation implies that the system doesn't include any point bellow the parabola y = -x² - x + 1, and the second equation implies that the system must include only points above the parabola y = 2x² + 3

From the given data-set, we have that:

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

To find the correlation coefficient, we find the same strategy, inserting these points into a calculator of correlation coefficients.

From the data, the points are given as follows:

(3, 7), (4, 8), (5, 10).

Hence the correlation coefficient is of:

r = 0.982.

The line of best-fit is given by:

y = 1.5x + 2.33.

Which has a slope of 1.5 and an intercept of 2.33.

The linear function passing through points (1,7) and (2.5, 1) is given by:

y = -4x + 11.

A linear function, in slope-intercept format, is modeled according to the rule presented below:

y = mx + b

In which the coefficients are described as follows:

For this problem, the two points that form the function are given as follows:

(1,7) and (2.5, 1).

The slope is given by change in y divided by change in x, hence it is given by:

m = (1 - 7)/(2.5 - 1) = -4.

Then:

y = -4x + b.

When x = 1, y = 7, hence we can find the intercept b of the function as follows:

7 = -4(1) + b

b = 7 + 4

b = 11.

Hence the equation is:

y = -4x + 11.

SOLUTION

We want to find out at which points the lines

intersect.

To do this, we have to solve the equations simultaneously and look for the values of x and y.

This becomes

Dividing both sides by 1.5, we get x, this becomes

To get y, we substitute the x for 8 into equation 1 or 2. Let us use equation 1, we have

-6 is the value of X

The question can be answered by simply following the rules of angles of geometry. The rule that follows here is:

Rule: Vertically opposite angles are equal i.e whenever two straight lines cross, they create two pairs of equal vertically opposite angles.

Because, both the angles given in the question are vertically opposite to each other

Therefore, angle 80 degree = angle 86 + X

i.e   80 = 86 + X

-->   80 - 86 = X

-->   -6 = X

An additional 36 gallons of water will be pumped into the pool past 13 minutes

Constant rate of flow: The definition of a constant rate of flow rate shows how fluid of a certain volume moves through a segment in a specified amount of time. Instead of measuring how quickly a fluid moves from point A to point B, the motion of fluids is examined by figuring out its flow rate. Specifically, how much fluid volume moves from point A to point B in a given amount of time.

Time for which water has been pumped into the pool = 13 minutes

Rate of flow of water = 24 gal/min

So, water pumped in 1.5 minutes = 24*1.5 = 36 gallons

Total water pumped in the pool in 14.5 minutes = 24*14.5 = 348 gallons

The correct answer for the limit expression is √2 (π/4)(π - 5).

What is limit?

In mathematics, the value of the limit of a function always approaches as input and finally it approach to some value. It is used for the calculation of the continuity function, derivatives or calculus.

According to the question, the value of the variable 'x' should be substituted in the limit expression.

Now, the required expression will be:

[tex]\lim_{x \to \\pi /4} (secx)(4x^{2} -5x) = sec(\pi/4)(4(\pi /4)^{2} -5(\pi /4))[/tex]

Now, the value of the sec(pi/4) is √2

⇒ √2((π²/4)-5(π/4)) = √2 (π/4)(π - 5)

Hence, the correct answer for the limit expression is √2 (π/4)(π - 5).

The weakness of plotting a scatterplot is given below

What is a scatterplot?

A scatterplot (also known as a scatter plot, scatter graph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that uses Cartesian coordinates to represent values for a collection of data for generally two variables. One more variable can be presented if the points are coded (color/shape/size). The data is represented as a collection of dots, with the value of one variable defining the horizontal axis and the value of the other variable determining the vertical axis. A scatterplot can be used when one continuous variable is within the experimenter's control and the other is reliant on it, or when both continuous variables are independent.

The estimation technique that will yield a solution that is closest to the actual product of (–21.06) (–30.45) is: rounding to the nearest tenth.

Given data  or information :

Actual Product  =  ( – 21.06) (– 30.45)

Now let estimate the product by approximating the product to the nearest tenth.

Approximation :

So,

- 21.06 = - 21.1 ( Approximately )

- 30.45= - 30.5 ( Approximately )

Hence , her estimate can be calculated as :

Estimate :

Estimate =  ( - 21.1) (-30.5)

Estimate = - 643.55

Therefore the estimation technique that will yield a solution that is closest to the actual product of (–21.06) (–30.45) is: rounding to the nearest tenth.

Answer:

Answer C
This statement is  not true

Step-by-step explanation:

Logarithms result in real values only for positive values of the argument i.e. log(x) results in a real value only for x > 0 So A is correct

Range is set of all real numbers -∞ < x < ∞ So B is correct

D is also correct. At x = 0, log is not defined

Only C is incorrect. If 0 < a < 1 the graph actually shows a downward trend ie logarithmic decline instead of growth

Answer:

y = - 2x + 12

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (6, 0 ) and (x₂, y₂ ) = (- 1, 14 )

m = [tex]\frac{14-0}{-1-6}[/tex] = [tex]\frac{14}{-7}[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (6, 0 )

0 = - 12 + c ⇒ c = 0 + 12 = 12

y = - 2x + 12 ← equation of line
