The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 467) and (10, 647)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (647 - 467)/(10 - 2)

Evaluate

Rate = 22.5

This means that the rate of change is $22.5

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 22.5

So, we have

y = 22.5(x - x1) + y1

Using one of the points, we have

y = 22.5(x - 6) + 467

Set x = 0

So, we have

y = 22.5(0 - 6) + 467

Evaluate

y = 332

Hence, the initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The value of the factorial expression is 99/10

The expression is given as

98!/100! x 10

The above expression implies that we multiply 10 by the quotient of 98! and 100!

This can be done directly using a calculator, and it can be solved step by step

The step by step procedure is as follows

Expand the denominator

98!/100! x 10 = 98!/100 * 99 * 98! x 10

Evaluate the quotient

98!/100! x 10 = 1/100 * 99 x 10

This gives

98!/100! x 10 = 1/10 * 99

Evaluate the product

98!/100! x 10 = 99/10

Hence, the value of the factorial expression is 99/10

The dimensions of the rectangular playing field are:

length = 92 yards and

width = 24 yards.

Given, the perimeter of the rectangular field is : 232 yards.

From the given question, length of the field is 4 yards less than quadruple the width.

hence, let the width of the field be x yards.

Length of the field = 4x - 4 yards.

we know that perimeter of the rectangle = 2(l+w)

therefore, substitute the values in the above formula:

2(4x - 4 + x) = 232

2(5x - 4) = 232

multiply the terms.

10x - 8 = 232

arrange the constants on one side.

10x = 232 + 8

10x = 240

x = 240/10

x = 24

hence we get the width as x = 24 yards.

Now substitute the value of x to find out the value of the length.

therefore, l = 4x - 4

l = 4(24) - 4

l = 96 - 4

l = 92

Therefore length and width of the rectangular field is 92 and 24 yards respectively.

y(2.5) = 15.9389 is Use euler's method with step size 0.1 to estimate y(2.5), where y(x) is the solution of the initial-value problem.

What is euler's method?

First-order methods, such as the Euler method, have local errors that are proportional to the square of the step size and global errors that are proportional to the step size.

f(x,y) = 3y+2xy

So, starting at t0 = 2, repeat the above sequence until t0>2.5

a) m = f(2,1) = 3(1)+2(2)(1) = 7

b) y1 = y0 + hm = 1+0.1(7) = 1.7

c) t1 = t0 + h = 2.1

d) show t1 and y1

e) t0 = t1 = 2.1

f) y0 = y1 = 1.7

2nd iteration

a) m = f(2.1,1.7) = 3(1.7)+2(2.1)(1.7) = 5.1 + 7.14 = 12.24

b) y1 = y0 + hm = 1.7+0.1(12.24) = 1.7 + 1.224 = 2.924

c) t1 = t0 + h = 2.2

d) show t1 and y1

x = 6

Since B is in the middle of A and C, AB + BC = AC

So,

2x - 11 + 8 = x + 3

x - 3 = 3

x = 6

Answer:

x = 85

Step-by-step explanation:

the exterior angles of a polygon sum to 360°

note the exterior angle at P = 180° - 90° = 90°

sum the 4 exterior angles and equate to 360

x + 72 + 113 + 90 = 360

x + 275 = 360 ( subtract 275 from both sides )

x = 85

The equations of the three perpendicular bisectors in the triangle ABC are y = - (1 / 2) · x + 9 / 4, x = 2 and y = - (6 / 7) · x + 24 / 7.

Triangles are polygons with three sides and three perpendicular bisectors, whose equations need the informations of slopes and midpoints of each side. Bisectors are lines that partitions line segments in two parts of equal length.

First, determine the midpoints of each side:

Side AB

M₁(x, y) = 0.5 · (- 3, 0) + 0.5 · (0, 6)

M₁(x, y) = (- 1.5, 0) + (0, 3)

M₁(x, y) = (- 1.5, 3)

Side BC

M₂(x, y) = 0.5 · (0, 6) + 0.5 · (4, 6)

M₂(x, y) = (0, 3) + (2, 3)

M₂(x, y) = (2, 6)

Side AC

M₃(x, y) = 0.5 · (- 3, 0) + 0.5 · (4, 6)

M₃(x, y) = (- 1.5, 0) + (2, 3)

M₃(x, y) = (0.5, 3)

Second, determine the slope of the perpendicular bisectors:

Side AB

m = (6 - 0) / [0 - (- 3)]

m = 2

m' = - 1 / m

m' = - 1 / 2

Side BC

m = (6 - 6) / (4 - 0)

m = 0

m' = - 1 / m

m' = NaN  (Vertical line)

Side AC

m = [4 - (-3)] / (6 - 0)

m = 7 / 6

m' = - 1 / (7 / 6)

m' = - 6 / 7

Third, derive the equations of the bisectors:

Side AB

b = 3 - (- 1 / 2) · (- 1.5)

b = 9 / 4

y = - (1 / 2) · x + 9 / 4

Side BC

x = 2

Side AC

b = 3 - (- 6 / 7) · (0.5)

b = 24 / 7

y = - (6 / 7) · x + 24 / 7

The equations of the three perpendicular bisectors in the triangle ABC are y = - (1 / 2) · x + 9 / 4, x = 2 and y = - (6 / 7) · x + 24 / 7.

The other root of the given quadratic equation is a = ± 3/√2.

Given that, x=2 and x²+ax+12=0.

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.

Now, put x=2 in x²+ax+12=0 and find the value of a.

That is, 2²+2a+12=0

⇒4+12+2a=0

⇒16+2a=0

⇒2a=-16

⇒a=-8

So, the value of a is -8.

Put (0, 6) and (4, 6) in the function y=2x²+bx+c and find the value of b and c.

That is, 6=2(0)²+b(0)+c

⇒ c=6

6=2(4)²+b(4)+c

⇒ 6 = 32+4b+c

⇒ -26 = 4b + 6

⇒ 4b = -32

⇒ b = -8

So, the value of b is -8 and the value of c is 6.

Put x=a (root) in the equation 2x + x/a -9 = 0 and find the other root.

That is, 2a²+a/a -9 = 0

⇒ 2a² - 9 = 0

⇒ a²=9/2

Answer:

[tex]y = -5x - 23[/tex]

Step-by-step explanation:

To write an equation in the slope-intercept form for a line, given the coordinates of a point on the line as well as the line's slope, we use the following formula:

[tex]\boxed{y - y_1 = m(x - x_1)}[/tex],

where [tex]m[/tex] is the slope of the line and [tex](x_1, y_1)[/tex] are the given coordinates of a point.

In this question, we are told that the slope is -5 and the coordinates of a point passing through the point are (-3, -8).

Therefore, using the above formula, we can write:

[tex]y - (-8) = -5(x - (-3))[/tex]

⇒ [tex]y + 8 = -5(x + 3)[/tex]

⇒ [tex]y + 8 = -5x - 15[/tex]           [Distributing -5 into the brackets]

⇒ [tex]y = -5x - 15 - 8[/tex]           [Subtracting 8 from both sides]

⇒ [tex]y = -5x - 23[/tex]
