Answer: -2.4, -2.25, -11/5, 15/10, 1.6

Step-by-step explanation:

The lowest number would be -2.4. Before you put these numbers in order you will have to convert the -11/5 into -2.2, and the 15/10 into 1.5. After doing this you can put the numbers in order from the lowest of -2.4 the -2.25 the -2.2 and then the numbers switch to positive and 15/10 and then final the highest of 1.6

Answer:

Option A

Step-by-step explanation:

Weight of an apple = twice of the weight of a lemon

Weight of an apple = 2(weight of a lemon)

x = 2y ------(1)

x = weight of an apple

y = weight of a lemon

Number of apples in a box = 16

Weight of the apple box (A) = 16x

Number of lemons in another box = 24

Weight of the lemon box (B) = 24y

Therefore, [tex]\frac{A}{B}=\frac{16x}{24y}[/tex]

[tex]\frac{A}{B}=\frac{2x}{3y}[/tex]

[tex]\frac{A}{B}=\frac{2(2y)}{3y}[/tex] [From equation (1)]

[tex]\frac{A}{B}=\frac{4y}{3y}[/tex]

[tex]\frac{A}{B}=\frac{4}{3}[/tex]

Option A will be the correct option.

Answer:

x =22

Step-by-step explanation:

The two angles are corresponding angles , so the angles are equal

x+14 = 5x-74

Subtract x from each side

x+14-x = 5x-x-74

14 = 4x-74

Add 74 to each side

14+74 = 4x-74+74

88 = 4x

Divide by 4

88/4 = 4x/4

Step(i):-

Given Ellipse   9 x² + 4 y² = 36

                     [tex]\frac{9x^{2} }{36} + \frac{4y^{2} }{36} =1[/tex]

               ⇒     [tex]\frac{x^{2} }{4} + \frac{y^{2} }{9} = 1[/tex]

Step(ii):-

  The Major axis lies on y-axis

   Foci of the Formula C² = a² -b² = 9-4 =5

                                 C = √5

The Foci is always lie on the major axis(longest) axis, spaced equally each side of the centre

Given ellipse of the foci is lie on Y- axis

Answer:

f(-2) = 13

g(4)  = -9

Explanation:

Whenever a question is asking you to find something like, in this example, f(-2) or g(4), you have to substitute whatever number is in the parentheses for every x in the function with that letter.

Let's try to find f(-2). We have to substitute -2 for every x in the function f and simplify:

[tex]f(-2) = -2 (-2)^{3} -3\\f(-2) = -2(-8)-3\\f(-2) = 16 - 3 \\f(-2) = 13[/tex]

Therefore, [tex]f(-2) = 13[/tex].

Next, let's try to find g(4). We have to substitute 4 for every x in the function g and simplify:

[tex]g (4) = -2(4) - 1\\g(4) = -8-1\\g(4) = -9[/tex]

Therefore, [tex]g (4) = -9.[/tex]

Answer:

Overall, the steps for algebraically finding the range of a function are:

1.Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

2.Find the domain of g(y), and this will be the range of f(x).

3.If you can't seem to solve for x, then try graphing the function to find the range.

Step-by-step explanation:

Answer:

Write down y=f(x) and then solve the equation for x, giving something of the form x=g(y).

Find the domain of g(y), and this will be the range of f(x).

If you can't seem to solve for x, then try graphing the function to find the range.

Answer:

False

Step-by-step explanation:

When a figure is dilated by a scale factor of 4, the new figure produced will be 4 times the size of the original figure. This means that, the size would change while the shape remains the same as the original figure.

Congruent figures must have the same shape and size.

Therefore, the figure produced when a dilation of scale factor of 4 is done is not a congruent figure. Rather, it is a similar figure.

So, get statement is FALSE.

The z - score for the Stephanie’s exam grade will be 1.

What is Standard deviation?

Standard deviation is the measure of dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

Given that;

The grades on a physics midterm at Covington are roughly symmetric with μ = 72 and σ = 2.0.

And,  Stephanie scored 74 on the exam.

Now,

The formula for the z - score = ( X - μ ) / σ

Substitute all the values, we get;

The z - score for the Stephanie’s exam grade = ( 74 - 72 ) / 2.0

                                                                       = 2 / 2

                                                                       = 1

Thus, The z - score for the Stephanie’s exam grade will be 1.

Answer:

64º

Step-by-step explanation:

We can find ∠F by looking at triangle BDF. A triangle's interior angles add up to 80º. We know that ∠B=77º and ∠D=39º, and ∠B+∠D+∠F=180º. So, 77º+39º+∠F=180º. Therefore, 116º+∠F=180º, and ∠F=64º.

Based on the information given, the value of angle F is 64°.

From the information given, it was stated that angle A=74º, angle B=77º, angle C=70º, angle D=39º, and angle E=36º.

Therefore, the measure of angle F in degrees will be calculated thus:

B + D + F = 180°

77° + 39° + F = 180°

116° + F = 180°

F = 180° - 116°

F = 64°

The line perpendicular to the line y = 2/3x + 4 is 4) y = -3/2x + 4.

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

The given equation of a line in slope-intercept form is y = (2/3)x + 4.

Now, We know lines perpendicular to each other have slopes that are negative reciprocal to each other.

If one line has a slope of 'm' the line perpendicular to it will have slope

(-1/m).

Therefore, From the given options the line y = -(3/2)x + 4 is the line perpendicular to the line y = (2/3)x + 4.

Given:

The equations are

[tex]5y=2x-5[/tex]

[tex]5y=4+3x[/tex]

[tex]5y-3x=-1[/tex]

To find:

The two parallel lines.

Solution:

Slope intercept form of a line is

[tex]y=mx+b[/tex]

where, m is slope and b is y-intercept.

Isolate variable y in each of the given equations, to get the slope intercept form of the lines.

The slope intercept forms of given lines are

[tex]y=\dfrac{2}{5}x-1[/tex]

[tex]y=\dfrac{4}{5}+\dfrac{3}{5}x[/tex]

[tex]y=-\dfrac{1}{5}+\dfrac{3}{5}x[/tex]

On comparing these equations with slope intercept form, we get

Slope of I line = [tex]\dfrac{2}{5}[/tex]

Slope of II line = [tex]\dfrac{3}{5}[/tex]

Slope of III line = [tex]\dfrac{3}{5}[/tex]

Slope of parallel lines are equal. So, lines II and III are parallel because their slopes are equal.

Therefore, the correct option is C.
