Answer:

c.) y = -3x - 2

Explanation:

Given following:

Equation:

[tex]\sf y - y_1 = m(x - x_1)[/tex]

[tex]\sf y - 10 = -3(x - (-4))[/tex]

[tex]\sf y - 10 = -3(x + 4)[/tex]

[tex]\sf y = -3x -12 + 10[/tex]

There are 15 / 2 ways to distribute 11 identical candies between 4 children such that each child receives at least 2 candies.

If we give child A four candies and so we were left with 9 candies.

In addition, we will take child A away from consideration to ensure he received exactly four candies, and thus we were left with 9 dots and 2 slashes, separating the 4 remaining distinct children.

So the possible ways are:  (11 + 4 / 2) = (15 / 2).

B- Jenny must have driven more than 48 miles.

Step-by-step explanation:

If Jenny rode for 60 at 48 mph, it would be exactly 48 miles. Though there is only 60 minutes in an hour, and Jenny rode 5 minutes longer than that, her drive being 65 minutes. To find how much she rode, 5 extra minutes into an hour would divide equally into 60, resulting in 12. Divide 48 by 12, and Jenny would have driven 4 miles in the 5 minutes drive after 60 minutes.

(Jenny basically driven 52 miles in 65 minutes).

The area of square LMNP is 50

A circle is the locus of points equidistant from a fixed point which is known as the center of the circle.

A circle is defined if the center and the radius is known.

Analysis:

Perimeter of a circle = 2πr

Given perimeter = 10π

2πr = 10π

2r = 10

r = 10/2 = 5

r = MO

so the diagonal of the square is actually the diameter of the circle = 5+5 = 10

To find the side, x of the square the diagonal and the sides form a right-angled triangle, by  Pythagoras, [tex]10^{2}[/tex] = [tex]x^{2}[/tex] + [tex]x^{2}[/tex]

2[tex]x^{2}[/tex] = 100

[tex]x^{2}[/tex] = 100/2 = 50

Also area of square is [tex]x^{2}[/tex] = 50

In conclusion, the area of square LMNP is 50

A geometric progression is a sequence that involves a rate, causing a change in the subsequent values of the sequence with respect to the given rate.

The answers to the given question are as follows:

a. It is a geometric progression.

b. Radius of the 6th circle ≅ 23. 73 ft.

c. The total length, l, can be determined by: l = ∑0.75[tex]R_{i}[/tex], i = 1 to n.

Geometric progression involves a change in the subsequent values of a given sequence due to a rate. So considering the given question, the circular iceberg melts at a certain rate per hour. Thus its radius decreases at the given rate per hour.

a. Therefore it can be deduced that the question is on geometric progression.

b. To determine the radius of the 6th circle, the:

radius of the 1st circle = 100 ft

radius of the 2nd circle = 0.75 x 100

                                        = 75 ft

radius of the t3rd circle = 0.75 x 75

                                        = 56.25 ft

radius of the 4th circle = 0.75 x 56.25

                                         = 42.1875 ft

radius of the 5th circle = 0.75 x 42.1875

                                        = 31.640625 ft

radius of the 6th circle = 0.75 x 31.640625

                                      = 23.73046875 ft

Thus the radius of the 6th circle is approximately 23. 73 ft.

c. Since the process is assumed to continue forever, let the number of hours required to be represented by n, and each radius of the iceberg be represented by R.

So then, we can say that the total length, l, of all the circles' radii is will be given by:

              l = ∑0.75[tex]R_{i}[/tex], i = 1 to n

The age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.

An equation is a mathematical statement with an 'equal to=' symbol between two expressions that have equal values.

Here, Let the age of the Caleb's be x years.

then age of Amir's be x/2 years.

also age of Balu's be 3x/4 years.

In 5 years,

Caleb's age = (x+5) years

Amir's age = (x/2 + 5) years

Balu's age = (3x/4 + 5) years

Now, According to question;

Amir's age + Balu's age = 16 + Caleb's age

(x/2 + 5) + (3x/4 +5) = 16 + (x + 5)

x/2 + 3x/4 - x = 16 + 5 - 5 - 5

(2x + 3x - 4x)/4 = 11

x/4 = 11

x = 4 X 11

x = 44

Now, Caleb's age = 44 years

         Amir's age = 44/2 = 22 years

         Balu's age = 3X44/4 = 33 years

Thus, the age of the brothers Caleb, Amir and Balu is 44 years, 22 years, and 33 years respectively.

The coordinates of the image after a reflection over the x-axis are A(-2,3) ,B(0,3), and (-1,1).

Given The coordinates of the triangle ABC are A(-2,3) B (0,3) and C(-1,-1).

We know that the coordinates of x axis used to be positive in first and fourth quadrant. The coordinates of y axis used to be positive in second and first quadrant. The coordinates of x axis are to be negative in second and third quadrant. The coordinates of y-axis used to be negative in third and fourth quadrant.

We have to reflect the triangle over x-axis so the values of y-axis needs to be positive. So we need to just convert the coordinates of y to positive numbers which will make the coordinates as under:

A (-2,3) will not change because it is already positive.

B(0,3) will not change as it is is also positive.

y = 1/2 x -2

Step-by-step explanation:

rise/run from (-6, -5) to (-4, -4) = 1/2

(rise 1, run 2)

meaning that slope (m) = 1/2

we can now rewrite our points in y=mx + b formatting:

y = mx + b

-5 = (1/2)(-6) + b

-4 = (1/2)(-4)+b

now, let's solve for b

-5 = (1/2)(-6) + b

-5 = -3 + b

-2 = b

-4 = (1/2)(-4)+b

-4 = -2 + b

-2 = b

So, the equation for our line is y = [tex]\frac{1}{2}[/tex] x- 2

The value of the y-intercepts of f(x) and g(x) is f(0), g(0) which gives -4.

An equation is an expression that shows the relationship between two or more variables and numbers.

The y intercept of an equation is the value of the function when x = 0.

Given that f(x) = -4(1.09)ˣ

f(0) = -4(1.09)⁰ = -4

From the table of g(x), when x = 0, g(0) = -4

The value of the y-intercepts of f(x) and g(x) is f(0), g(0) which gives -4.
