Answer:

C) as x –> ∞, q(x) –> –∞, and as x –> -∞, q(x) –> –∞

Step-by-step explanation:

use the end behavior chart to figure out the end directions of the graph. remember these

   E   O

+|↑↑|↓↑

–|↓↓|↑↓

all you need to do is look at the first number of the equation and ask yourself:

1. Is the first number even or odd?

2. is the first number positive or negative?

find where the answers to both meet on the chart.

so, in this question, the first number is even and negative. when using the chart we see that they meet at the ↓↓ which means that the end behavior on both sides is going towards negative infinity.

Using the normal distribution, the value that separates the highest 70% of the scores in a normal distribution from the lowest 30% is:

z = -0.52.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The value that separates the highest 70% of the scores in a normal distribution from the lowest 30% is is the 30th percentile, which is Z with a p-value of -0.3, hence z = -0.52.

Step-by-step explanation:

Hello!

We are basically asked to find the circumference of the Earth's cross-section.

Circumference: [tex]C = 2\pi r[/tex]

We can replace 2r with the diameter, because the diameter is 2 times the radius.

Multiply the Diameter by pi:

It is around 25,132.74 miles around.

The value for x and y are 140° and 70° respectively.

There are two ways to solve polygon question. Formula for the sum of interior angle and sum of the  exterior angle of regular polygon.

Sum of the interior = (n - 2)180

Sum of the exterior = 360/n

Where n = number of sides of a polygon.

The regular polygon in which x is one of its angle is called decagon

Sum of the interior = (n - 2)180

n = 10

Substitute n into the formula

Sum of the interior angle = (10 - 2)180

Sum of the interior angle  = (8)180

Sum of the interior angle = 1440

Each angle = 1400/10

x = 140°

For y, the three angles are similar.

sum of angle in a triangle = 180

Since the each triangle is an isoceles triangle, angle at each base will be y

40 + y + y = 180

2y = 180 - 40

2y = 140

y = 70°

Therefore, the value for x and y are 140° and 70° respectively.

The area of the rectangular patio to be painted is: B. A = (x + 20)(x + 10) - 12.

A rectangle, by definition, is a quadrilateral with two pairs of opposite that have the equal lengths. All four angles of a rectangle are right angles (90 degrees).

The area of a rectangle = (length of rectangle)(width of rectangle).

Given the following parameters for the patio and the bench:

Area to be painted = area of rectangular patio - area of rectangular bench

Area of rectangular patio = (x + 20)(x + 10)

Area of rectangular bench = (6)(2) = 12

This function will have a minimum point only if f(x) has one.

Examples:  

y = x + 5:  straight line with no minimum

y = x^2 + 5:  parabola that opens up and has vertex at (0, 5); thus, the minimum is (0, 5)

What f(x) did you have in mind?  Please share it.

The domain of the function f(x) is:

11 ≥ x

Here we have the function:

[tex]f(x) = \sqrt{11 - x}[/tex]

Now, remember that the argument of a square root can only be a number equal to or larger than zero, so the domain of our function is defined by:

The length of the rectangle = 2 - (1/3n) +(3/n²).

The formula for the area (taking this exists as a rectangle)

Area = length ⋅ width

where A exists the area of the rectangle

l exists the length of the rectangle and w exists the width of the rectangle.

If Area of the rectangle = length ⋅ width

then length of the rectangle = area/ width

Area = 6n² − n +9​

width = 3n²

Area = length [tex]*[/tex] width

length = area/ width

= (6n²  − n +9)/3n²

= 2 - (1/3n) +(3/n²).

Slope is rise over run. The graph decreases by 5 units every 1 unit to the right, so the slope is -5.

Step-by-step explanation:

324+x²=729

x²=405===> x=√405===> 9√5

The pythagorean theorem (leg 1)2 + (leg 2)² = (hypotenuse)² the values is about 8.5, -8.5.

The Pythagorean theorem is used to find the length of the sides of a right triangle, not for solving equations like x² = 72.

To solve the equation x² = 72,  to take the square root of both sides to find the value of x:

√(x²) = √(72)

Since the square root of x² is x (the absolute value of x), the equation simplifies to:

x = √(72)

Now, let's find the approximate value of √(72):

√(72) ≈ 8.49

So, the equation becomes:

x≈ 8.49

Now, remember that the absolute value of x is a positive value, so the equation gives two possible solutions for x:

x= 8.49 → x = 8.49

x = -8.49 → x = -8.49

Rounded to the nearest tenth, the solutions are:

x ≈ 8.5 and x ≈ -8.5

Answer:

2 face cards

Step-by-step explanation:

By definition, there are 12 face cards (Kings, queens, and jacks) and 36 numbered cards (2's through 10's) in a standard deck of 52 cards.  Aces are not considered face cards (no face on the card).

The ratio of face cards in a full deck is (12/52) or slightly over 23%.

The likelihood of a face card in a hand of 8 cards is:

(8 cards)*(12 face cards/52 cards) = 1.85 cards.  We need to round to the nearest whole card, so the expected number of face cards in a hand of 8 is 2 cards.  

The standard equation of the circle is x² + y² + 8x - 9 = 0 if the circle with center at (-1,-4) that passes through the point (-4,0).

According to the question,

The circle with center at (-1,-4) that passes through the point (-4,0).

To find the radius of the circle:

Radius r = √[(-4 - (-1))² + (0- (-4))²]

=√(-4+1)² + (4)²

=√9+16

=√25

=5.

In order to find the standard equation of the circle is

(x - (-4))² + (y - (0))² = (5)²

(x + 4)² + (y )² = 25

x² + 8x + 16 + y² = 25

x² + y² + 8x + 16 = 25

x² + y² + 8x = 25 - 16

x² + y² + 8x = 9

x² + y² + 8x - 9 = 0

Hence, the standard equation of the circle is x² + y² + 8x - 9 = 0.
