Answer:

for every 2 seniors there are 3 juniors or 2:3

The ratio of seniors to total students will be 2: 5.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

There are 10 seniors and 15 juniors in a gym class.

The total number of students will be given as,

Total students = 10 + 15

Total students = 25

Then the ratio of seniors to total students will be given as,

Ratio = Seniors / Total student

Ratio = 10 / 25

Ratio = 2 / 5

The ratio of seniors to total students will be 2: 5.

Answer:

Length of third side is: [tex]\mathbf{8m^3-4m^2+3m}[/tex]

Step-by-step explanation:

Perimeter of triangle = [tex]18m^3+2m^2-m[/tex]

Length of side 1= [tex]5m^3+3m^2-2m[/tex]

Length of side 2= [tex]5m^3+3m^2-2m[/tex]

We need to find length of third side.

The formula used is: [tex]Perimeter \:of\:triangle=Sum\:of\:all\:sides[/tex]

Putting values and finding length of third side.

[tex]Perimeter \:of\:triangle=Sum\:of\:all\:sides\\18m^3+2m^2-m=5m^3+3m^2-2m+5m^3+3m^2-2m+Length\:of\:3rd\:side\\18m^3+2m^2-m=5m^3+5m^3+3m^2+3m^2-2m-2m+Length\:of\:3rd\:side\\18m^3+2m^2-m=10m^3+6m^2-4m+Length\:of\:3rd\:side\\Length\:of\:3rd\:side=18m^3+2m^2-m-(10m^3+6m^2-4m)\\Length\:of\:3rd\:side=18m^3+2m^2-m-10m^3-6m^2+4m\\Length\:of\:3rd\:side=18m^3-10m^3+2m^2-6m^2-m+4m\\Length\:of\:3rd\:side=8m^3-4m^2+3m[/tex]

Answer:

The translated image point would then be (10, -6) (10, -6)

Step-by-step explanation:

The image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6)

A translation is a type of transformation that takes each point in a figure and slides it the same distance in the same direction.

Now the given points are,

(7,-5)(7,−5)

So, when the image points translates right 3 units there is change in x coordinate. Thus,

(7,-5)(7,−5)

= (7-3,-5) (7-3,−5)

= (4,-5)(4,−5)

and, when the image points translates down 1 unit there is change in y coordinate. Thus,

(4,-5)(4,−5)

= (4,-5-1)(4,−5-1)

= (4,-6)(4,−6)

Thus, the image point of (7,-5)(7,−5) after a translation right 3 units and down 1 unit is (4,-6)(4,−6).

Answer:

graph -4/1  and y intercept is 1

Step-by-step explanation:

Using proportions, we have that:

6. From the last pool, 46.43% of voters were for the candidate.

7. Janie makes the triple amount of Jenny.

8. The balance has increased by 3.02% during the year, not 3%.

9. The statement that 10% of the students in the class are men with blond hair is correct.

10. There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

For item 6, we have that:

Hence:

1.4x = 65

x = 65/1.4

x = 46.43%.

From the last pool, 46.43% of voters were for the candidate.

For item 7, we have that 200% more than a measure is given by:

x + 2x = 3x.

As the measure by itself is of 100%, hence:

Janie makes the triple amount of Jenny.

For item 8, we have that:

Hence the yearly increase is given by:

1.01 x 1.02 = 1.0302 = 3.02%.

The balance has increased by 3.02% during the year, not 3%, because the 2% increase on the second semester is over the 1% increase in the first semester, hence the coefficients are multiplied.

For item 9, we have that:

Hence:

0.2 x 0.5 = 0.1.

The statement that 10% of the students in the class are men with blond hair is correct.

For item 10, we have that:

There is a intersection between the percentages of Democrats and of union members, hence we can not affirm that the sets are independent and that 18% of the voters are Democrats who are union members.

Answer:

Initial Value: 25, Rate of change -5.

Step-by-step explanation:

First. Lets find the rate of change.

y2-y1/x2-x1 = m

We have A(1,20) B(3,10)

10-20/3-1=-5

m=-5(Rate of change)

Now let's find the initial value using slope-point form.

y-y₁=m(x-x₁)

y-20=-5(x-1)

=-5x+5+20

=-5x+25

The initial value is the value of y when the value of x is equal to 0. (Also the Y-Intercept)

Initial Value = -5(0)+25

=25

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Slope = [tex]\frac{6-4}{-1-0}[/tex]

9). Slope of a line passing through (10, 15) and (9, 0),

Slope = [tex]\frac{15-0}{10-9}[/tex]

          = 15

10). Slope of a line passing through (0, -9) and (4, -7),

Slope = [tex]\frac{-9+7}{0-4}[/tex]

          = [tex]\frac{1}{2}[/tex]

11). Slope of a line passing through (2, 20) and (4, 17),

1                  60

2                 45

3                 33.75

An arithmetic sequence can be defined as a series of real and natural numbers in which each term differs from the preceding term by a constant numerical quantity.

Mathematically, the nth term of an arithmetic sequence can be calculated by using this expression:

aₙ =  a₁ + (n - 1)d

Where:

After the first person cuts off 1/4, the piece of paper left is given by:

Fraction = 1/4 × 80

Fraction = 20

Remainder = 80 - 20 = 60 square inches.

After the second person cuts off 1/4, the piece of paper left is given by:

Fraction = 1/4 × 60

Fraction = 15

Remainder = 60 - 15 = 45 square inches.

After the second person cuts off 1/4, the piece of paper left is given by:

Fraction = 1/4 × 45

Fraction = 11.25

Remainder = 45 - 11.25 = 33.75 square inches.

⇒ Average rate of change = f(b) - f(a)  / b - a

                                            = (27 - 6) / (4 - (-3))

                                            = 21 / 7

The coordinates of the vertices of the image of the triangular figure with vertices (-5, -3), (-2, -9), (-5, -8) are the points (3, 3), (6, -5), (7, -2)

A reflection transformation is one in which the image points are mirrored about a line of reflection.

The coordinates of the vertices of the triangle following a reflection about the line y = -2·x - 3 can be found as follows;

The coordinates of the vertices of the triangle are; (-5, -3), (-2, -9), (-5, -8)

The slope of the line y = -2·x - 3 is m₁ = -2, therefore, the slope, m₂ of the line of reflection is m₂ = -1/(-2) = 1/2

The equations of the line of reflection are therefore;

y = (1/2)·(x + 5) - 3 = 0.5·x - 0.5

y = 0.5·x - 0.5

The point of intersection can therefore be found as follows;

0.5·x - 0.5 = -2·x - 3

Which indicates, using an online calculator, x = -1

y = 0.5 × (-1) + 0.5 = 0

The point of intersection of the line from (-5, -3) to the image and the line of reflection  is (-1, 0)

(x₁ + x₂)/2 = -1

(-5 + x₂)/2 = -1

x₂ = 3

Similarly; (y₁ + y₂)/2 = 0

(-3 + y₂)/2 = 0

y₂ = 3

The image of the point (-5, -3) following a reflection is (3, 3)

Equation of the line from point (-2, -9) is; y = 0.5·(x + 2) - 9

y = 0.5·x + 1 - 9 = 0.5·x - 8

The point of intersection is; 0.5·x - 8 = -2·x - 3

Which indicates x = 2 and y = -7

(x₁ + x₂)/2 = 2

(-2 + x₂)/2 = 2

x₂ = 6

Similarly; (y₁ + y₂)/2 = -7

(-9 + y₂)/2 = -7

y₂ = -5

The coordinate of the point (-2, -9) following a reflection about the line y = -2·x - 3 is (6, -5)

The equation from the perpendicular line to the line of reflection from the point (-5, -8), is; y = 0.5·(x + 5) - 8 = 0.5·x + 2.5 - 8 = 0.5·x - 5.5

y = 0.5·x - 5.5

The point of intersection with y = -2·x - 3 is therefore at the point; 0.5·x - 5.5 = -2·x - 3

x = 1

y = -5

(x₁ + x₂)/2 = 1

(-5 + x₂)/2 = 1

x₂ = 7

Similarly; (y₁ + y₂)/2 = -5

(-8 + y₂)/2 = -5

y₂ = -2

The coordinate of the point (-5, -8) following a reflection about the line y = -2·x - 3 is (7, -2)

We have a translation 3 units downwards and 4 units to the right. So the equation is:

g(x) = ∛(x - 4) - 3

We know that g(x) is a transformation of the parent cube function, which is f(x) = ∛x

If we look at the image, we can see that the graph of g(x) is exactly like the graph of f(x), but translated 3 units downwards and 4 units to the right.

A vertical translation of N units is written as:

g(x) = f(x) + N

A translation of 3 units downwards is written as:

g(x)= f(x) - 3

A horizontal translation of N units is written as:

g(x) = f(x + N)

Then a translation of 4 units to the right is:

g(x) = f(x - 4) - 3

Replacing the function f(x) we get:

g(x) = ∛(x - 4) - 3

That is the transformed function. So the correct option is D
