Answer:

Your answer would be D, the equation is a function because it is a polynomial and all polynomials are functions.

Step-by-step explanation:

I like to remember that polynomials have no negative , fraction exponents and no division. In this case everything is positive so I knew it was a polynomial , and like the answer says all polynomials are functions !

Hope this helped

A system of equations is given below.

MAVERICK [17]

First, solve the given system of linear equations.

Second, multiply the first equation by 4 (which was an arbitrary choice). Add your result to the 2nd equation.

You should now have the following:

First equation: No change: <span>2x + 7y = 1

Second equation: 4(</span><span>-3x – 4y = 5) = -12x -16y = 20

Solve this new system of linear equations. Do you (or do you not) obtain the same solution as your earlier one?</span>

Section 5.2 Problem 17:

Elina [12.6K]

This DE has characteristic equation

$4r^2 - 12r + 9r = (2r - 3)^2 = 0$

with a repeated root at r = 3/2. Then the characteristic solution is

$y_c = C_1 e^{\frac32 x} + C_2 x e^{\frac32 x}$

which has derivative

${y_c}' = \dfrac{3C_1}2 e^{\frac32 x} + \dfrac{3C_2}2 x e^{\frac32x} + C_2 e^{\frac32 x}$

Use the given initial conditions to solve for the constants:

$y(0) = 3 \implies 3 = C_1$

$y'(0) = \dfrac52 \implies \dfrac52 = \dfrac{3C_1}2 + C_2 \implies C_2 = -2$

and so the particular solution to the IVP is

$\boxed{y(x) = 3 e^{\frac32 x} - 2 x e^{\frac32 x}}$

A bicycle wheel makes five rotations. the bicycle travels 44.48 ft. Find the diameter of the wheel in inches.

Tema [17]

Answer:

2.42 feet

Step-by-step explanation:

the bicycle wheel rotates 5 times and travels 37.94 feet, then we know that the circumference of the wheel (the outside of the wheel as it touches the ground 5 times around) is 37.94/5 = 7.588

Then we use the formula for the circumference of a circle: 2(pi)(radius) = circumference

We plug in what we know 2(3.14)(radius) = 7.588 and then solve for the radius

We divide 2 from both sides of the equation (3.14)(radius) = 3.794

We divide pi from both sides (radius) = 1.208

Then the last step, we multiply the radius by 2, because we need the diameter, which is double the radius

1.208 * 2 = 2.416 or 2.42 rounded up

Final answer = 2.42 feet
