The equation in slope-intercept form of a line whose slope is 9 and whose y-intercept is -3 is equals to the y = 9x-3.

Slope intercept form of an equation : The slope intercept form is one of method to determine the equation of a straight line in the coordinate plane. The equation of a straight line is a relation which:

Let us assume a straight line of slope 'm' and y-intercept 'b'. The equation of slope intercept form for a straight line with slope, say, 'm', and the y-intercept, 'b', is

y = mx + b

Now, the slope of line , m = 9

y-intercept of line, b = - 3

As we know slope intercept form of a line is, y = mx + b , so plugging the known values of slope and y-intercept in it,

=> y = 9x - 3

So, required equation in slope intercept form of line is y = 9x - 3.

We may apply the simple interest formula to find the due date for repayment from Mikos is 5 months.

I = P*r*t, where I represents interest, P the principal (initial sum), r the interest rate, and t the period of time in years.

The maturity value formula can be used to calculate interest given that the loan's principal is $100,000 and its maturity value is $104,375:

Where MV is the maturity value, P is the principal, and I is the interest, the formula is: MV = P + I.

With the above data, we obtain: 104,375 = 100,000 + I

  I = 4,375.

Now we can use this value of I to find the time t in years:

I = P*r*t

4,375 = 100,000 (0.105) t

t = 4.375 / (100,000 x 0.105)

t = 4.375 / 10,500

t = 0.417 years or approximately 5 months

 So, it takes approximately 5 months to repay the pay back amount .

Therefore, Mike must repay the amount by April 14, which is around five months after the day he took out the loan.

Therefore , the solution of the given problem of circle comes out to be 100 rotations of the front tire will be made by the back wheel.

Each point in the plane whose distance from that other point is a certain value forms a circle (center). It is therefore a curve composed of vertices that are spaced apart from one another in the plane by a specific amount. Furthermore, it is symmetrical about the center at all angles in terms of rotation. The closed, two-dimensional plane of a circle has all pairs of endpoints equally separated from the "center." When a line is drawn through the circle, a circle symmetry line is created. Furthermore, it rotates equally from all angles about the center.

Here,

The circle of the rear wheel is equal to circle = diameter x π, or 2.5 feet by 12 inches, or 30 inches.

The length of the front axle is 30 x 2 = 60 inches.

The diameter of the front wheel, C, is equal to 60 x Pi, or 60π, in inches.

The diameter of a back wheel is 4 x 2 = 8 inches.

The circumference of back wheel is C = 8 x Pi = 8π in inches.

750 revolutions are equal to

100 × [60Pi/8π] = 6,000π/8π.

100 rotations of the front tire will be made by the back wheel.

Step-by-step explanation:

Let the width be x, then the length is x+2 km.

Area = width * length

Substituting the given values:

24 = x(x + 2)

24 = x^2 + 2x

x^2 + 2x - 24 = 0

(x + 6)(x - 4) = 0

x = -6, 4

As x must be positive, then x = 4.

So, the dimensions are 4 and 4+2

= 4, 6,

Answer:

width = 3.46 km and length = 6.93 km

Step-by-step explanation:

let the width be : X km

then the length would be: 2X km

as area is length x width

therefore:

2X x X = 24

2X² = 24

X² = 24/2

X² = 12

X = [tex]\sqrt{12}[/tex]

X=  3.46

The required system of equation is given as y = 3x + 12 and y=x³+4x²+3x+12.

The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.

Given equation,
y=x³+4x²+3x+12

To determine the x-intercept put equation y = 0

0 = x³+4x²+3x+12

Factorize the above equation

0=(x²+3)(x+4)

One of the factors from above is given as

x+4=0  

x = -4

The x-intercept is (-4,0)

For the y-intercepts, x=0 and solve.

First, we can use the fact that A, B, C, D, E, and F are concyclic and that D, E, and F are the midpoints of AB, BC, and AC respectively.

Let r be the radius of the circumcircle of triangle ABC. Then using the Pythagorean theorem, we can find that r = (151413) / (4*K) where K is the area of the triangle.

Now we can use the property that the perpendicular bisectors of any triangle pass through the circumcenter of the triangle. We know that the midpoint of a line segment is the foot of the perpendicular from that point to the other endpoint. Then we can use the property that the radius from the circumcenter of the triangle to the midpoint of a side is half the length of that side.

Therefore, the circumcenter of triangle BDE is located at X = (BD/2, DE/2) = (13/2, 7/2) and the circumcenter of triangle CEF is located at X = (CE/2, EF/2) = (15/2, 7/2).

So the coordinates of X are (13/2, 7/2) and since the circumcenter of a triangle is equidistant from each vertex of the triangle, we can find that XA = XB = XC = r = r = (151413) / (4*K)

Therefore, XA + XB + XC = 3r = 3(151413) / (4*K) = (195/8)

Basically, The real numbers R is the set of "all the numbers" on the number line that  includes the rationals and irrationals together.

The real numbers are an uncountably infinite set – there actually are far more real numbers than there are natural numbers, and there is no way to line up the reals and the naturals so that we are assigning exactly one real number to each natural number. Hence there is no possible way of counting the number it can be considered in the category of uncountably infinite.

For Sydney with $100 at 5%, monthly, for 10 year we get 229050.

Annual percentage rate (APR) refers to the yearly interest generated by a sum that's charged to borrowers or paid to investors. APR is expressed as a percentage that represents the actual yearly cost of funds over the term of a loan or income earned on an investment.

The interest rate is the amount a lender charges a borrower and is a percentage of the principal—the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).

Let the equation be

A = [ p(1 + r/n)nt ] + [ PMT ((( 1 + r/n)nt - 1) / (r / n)) ]

For Sydney with $100 at 5%, monthly, for 10 year

The surface area is approximately 100.5m².

Surface Area = πrl + πr²

Where r is the radius of the base and l is the slant height.

Surface Area = π(2m)(4m) + π(4m)²

Surface Area = 100.5m²

The surface area of a right circular cone can be calculated by using the formula surface area = πrl + πr². In this particular case, the height of the cone is 4m and the radius of the base is 2m. Therefore the surface area of the cone is calculated as follows: π(2m)(4m) + π(4m)² = 100.5m². This surface area includes both the base and sides of the cone.

A. The total number of points of intersection of the graphs of the equations y = 5e^x and xy = 20 is two.

To find the points of intersection, we must solve the two equations for x and y.

For the first equation, y = 5e^x, we can solve for x by taking the natural logarithm of both sides and getting x = ln(y/5).

For the second equation, xy = 20, we can solve for y by dividing both sides by x and getting y = 20/x.

We can then substitute the expression for x in terms of y into the expression for y in terms of x and solve for y to get y = 20/(ln(y/5)). This is a nonlinear equation that must be solved numerically.

By using numerical methods, we can solve the equation and find the two points of intersection, which are (x, y) = (3.68, 4.64) and (x, y) = (0.87, 22.95).

Next, we would determine the rate of change of the value of y with respect to the value of x on the scatter plot, which represents a line that is passing through the points (0, 800) and (10, 1200):

Rate of change, m = (1200 - 800)/(10 - 0)
