If the width is 9x², then the length is 27x^5+9x^4-18x^3/9x², which equals 3x³+x²+2x. ☺☺☺☺

Answer:

The length of the rectangle is given by 3x^3+x^2-2x

Step-by-step explanation:

We have been given that

area of rectangle is A=27x^5 + 9x^4 - 18x^3

The width of the rectangle is w=9x^2

We know the area of rectangle is given by

A=lw\\\\l=\frac{A}{w}

On substituting the known values, we get

l=\frac{27x^5 + 9x^4 - 18x^3}{9x^2}

On simplifying this, we get

l=\frac{27x^5}{9x^2} +\frac{9x^4}{9x^2} -\frac{18x^3}{9x^2} \\\\l=3x^3+x^2-2x

Therefore, the length of the rectangle is given by 3x^3+x^2-2x

Find the equations of the tangent lines to x2+y2=1 at x=0, x=1 and x=35.
Ivanshal [37]
Assuming the equation is x^2 + y^2 = 1, then that's a circle, with radius 1, centered on the origin [0,0].

So there are two tangents at x = 0. They are y = 1, and y = -1 (horizontal lines).

There is one tangent at x = 1. It is x = 1 (a vertical line).

There is no tangent at x = 35, because the original equation has no solution at x = 35.

A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function
nlexa [21]
H = - 16 t² + 36 t + 10
The maximum height of the ball is at the vertex of the parabola.
t = - b / 2 a
t = -36/-32
t = 1.12 s
The maximum height of the ball:
h max = - 16 * 1.12² + 32* 1.12 + 10 = - 16 * 1.2544 + 35.84 + 10 =
=  - 20.0704 + 45.84 = 25.7696 = 25.77 m

Answer:

the possible line of best fit equation is;

y = 10x + 24

Step-by-step explanation:

Here, we want to get the approximate line of best fit

Mathematically, we have the general line of best fit as

y = mx + b

where m is the slope and b is the y-intercept

By joining the given lines, we can see that the y-intercept values fall a little below 30

This means that the possible y-intercept value is 24

Now, to get the slope value, we select any two points and use the slope equation

We can have (3,50) and (6,80)

Using the slope equation;

m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10

The equation is thus;

y = 10x + 24
