The baker can put all the 576 muffins in the box that contains exactly 9 muffins with none left over.

In order to determine if the baker can put all the 576 muffins in the box that contains exactly 9 muffins with none left over, divide 576 by 9. If 9 perfectly divides 576, then there would be no remainder.

Division is the process in mathematics that is used to group a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other operations in mathematics are addition, subtraction and multiplication.

Number of boxes needed = number of muffins / capacity of each box

576 / 9 = 64

The domain and range are the set of all real numbers, so:

Domain: x ∈ R

Range: x ∈ R

Thus, the correct option is  the second one

For any function y = f(x), we define the domain as the set of the possible values of x (the ones on the horizontal axis) and the range is the set of the possible values of y (vertical axis).

In this case, we have a linear equation (you can see that the lines extend to the bottom left and the top right)

So both domain and range are the sets of all real numbers.

Thus, the correct option is  the second one.

Answer:

  angle 1 = 108°

Step-by-step explanation:

You want the measure of angle 1, given the measure of angle 4 is 72° in the diagram.

Angles 1 and 4 are a linear pair, so are supplementary:

  angle 1 + angle 4 = 180°

  angle 1 + 72° = 180°

  angle 1 = 108° . . . . . . . subtract 72°

Simplify the integrand.

[tex]\displaystyle \frac{x^3-x^2-1}{x^2-x-1} = x + \frac{x-1}{x^2-x-1}[/tex]

Expand into partial fractions, recalling that [tex]\phi[/tex] and [tex]-\frac1\phi[/tex] are roots to the quadratic in the denominator.

[tex]\dfrac{x-1}{(x - \phi) \left(x + \frac1\phi\right)} = \dfrac1{1+\phi^2} \left(\dfrac1{x-\phi} + \dfrac{\phi^2}{x + \dfrac1\phi}\right)[/tex]

Then the integral is

[tex]\displaystyle I = \int_0^1 \frac{x^3-x^2-1}{x^2-x-1} \, dx \\\\ ~~~~ = \int_0^1 x \, dx + \frac1{1+\phi^2} \int_0^1 \left(\frac1{x-\phi} + \frac{\phi^2}{x+\frac1\phi}\right) \, dx \\\\ ~~~~ = \frac12 + \frac{1}{1+\phi^2} \left(\ln|1-\phi| + \phi^2 \ln\left|1 + \frac1\phi\right| - \ln|-\phi| - \phi^2 \ln\left|\frac1\phi\right|\right)[/tex]

and this reduces significantly, when we recall that [tex]\phi = 1 + \frac1\phi[/tex], to

[tex]\displaystyle I = \boxed{\frac12 + \frac{2\phi}{1 + \phi^2} \ln(\phi)}[/tex]

If Gabriella has 3 more nickels than dimes and they have a combined value of 90 cents, The number of coin she have is; 4 nickels and 7 dimes.

x =  number of nickels that Gabriella has

x +3 =number of dimes that Gabriella

Hence,

0.05x  + 0.10 ( x + 3 ) = 0.9

Solving for x

Multiply both sides of the equation by 100 so as to eliminate two  decimal places

5x + 10x + 30 = 90

Collect like terms

15x  = 60

Divide both side by 15x

x = 60/15

x = 4 nickels

So,

x + 3 where x = 4

4 + 3 =7 dimes

Therefore she has 4 nickels and  7 dimes.

Explanation: 423 divided by 3/4 is 141, and 141 x 3/4 is 423

Answer:

(3, 0)

Step-by-step explanation:

I assume this means a clockwise rotation.

let's think this through logically :

the last option (0, 3) cannot be right, because that is F before the rotation. to go back to the original position requires a full rotation of 360° (remember, a circle has 360°, and that means to travel one complete time around the circle).

(0, -3) cannot be right, because this is just mirrored down, and would represent a turn of 180° (a half-circle).

for the other options imagine you use a math compass, put the pin on the origin, and the writing arm on F. and the you draw a circle through F.

(3, 0) is the result of the clockwise (right) turn of 90°, (-3, 0) would be the result of a counterclockwise (left) turn of 90°.

so, if my assumption above is incorrect, please pick (-3, 0) for the counterclockwise solution.

∠a=90° as the rays of the angles meet at the right angle that is 90°.One of the angle is 21, The remaining would be 90-21=69°.

When two straight lines or rays intersect at a common endpoint, an angle is formed. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

A ray is a vector that extends from one point to another. A ray is typically defined in geometry as a half-infinite line (also known as a half-line) with one of the two points and taken to be at infinity.

The right angle is formed when two straight lines intersect at 90 degrees or are perpendicular to each other at the intersection. The symbol is used to represent a right angle.∠

Here, The total sum of angles is 90°.

one the value is 21°. The value of adjacent angle would be,

remaining angle=90-21

                          =69°

So the remaining value of adjacent angle is 69°.

Answer:

Rounds down to 7000.

Step-by-step explanation:

Applying the Chain Rule, the derivatives are given as follows:

The function Z is defined as follows:

z = x^7y^7.

The variables x and y are functions of variables s and t, as follows:

Hence the derivative of z as a function of s is given as follows:

∂z/∂s = (dz/dx)(dx/ds) + (dz/dy)(dy/ds).

Hence, applying the derivative rules for the exponents, and for the exponents, we have that:

[tex]\frac{\partial z}{\partial s} = 7x^6y^7\cos{(t)} + 7y^6x^7\sin{(t)} = 7x^6y^6(y\cos{t} + x\sin{t})[/tex]

Replacing the values of x and y, we have that:

[tex]\frac{\partial z}{\partial s} = 7(s\cos{t})^6(s\sin(t))^6(y\cos{t} + x\sin{t})[/tex]

We follow the same logic as above, only that now the inside derivatives, that is, the derivatives of x and y, are as function of t and not of s, hence:

∂z/∂t = (dz/dx)(dx/dt) + (dz/dy)(dy/dt).

Then:

[tex]\frac{\partial z}{\partial t} = -7x^6y^7s\sin{(t)} + 7y^6x^7s\cos{(t)} = 7sx^6y^6(-y\sin{t} + x\cos{t})[/tex]

Then, replacing x and y as functions of s and t, we have that:

[tex]\frac{\partial z}{\partial t} = -7x^6y^7s\sin{(t)} + 7y^6x^7s\cos{(t)} = 7s(s\cos{t})^6(s\sin{t})^6(-y\sin{t} + x\cos{t})[/tex]

The points on the x-axis that are 12 units away from the point (3,-6) is       found to be  3 ±  [tex]6\sqrt{3}[/tex].

r² = (x - h)² + (y - k)²is the standard equation for a circle, where (h,k) are the coordinates of the circle's center and r is the radius.

We must locate all points on the x-axis that are 12 units away from the starting point (3,-6).

Let these points be (x,0)

All points 12 units away from the point (3,-6) form a circle with a radius of 12 and a center at (3,-6). The formula would be as follows:

r² = (x - h)² + (y - k)²

12² = (x-3)² + (0+6)²

144 = (x-3)² + 36

(x-3)² = 108

x-3 = ± [tex]\sqrt{108}[/tex]

x = ± [tex]\sqrt{108}+3[/tex]

x = 3 ± [tex]6\sqrt{3}[/tex]

Therefore, the points on the x-axis 12 units away from point (3,-6) is  calculated as  3 ± [tex]6\sqrt{3}[/tex].

The quotient of 581 and 14 has a value of 40.07

The quotient expression is given as

581/14

Next, we express 581 as the sum of a multiple of 14 and another number

Say 581 = 280 + 280 + 1

So, we have the following equation

581/14 = (280 + 280 + 1)/14

Expand the bracket

So, we have the following equation

581/14 = 280/14 + 280/14 + 1/14

Evaluate the quotients

581/14 = 20 + 20 + 0.07

Evaluate the sum

581/14 = 40.07

Factor of trinomial 8x+2x-3 is 4x-3(binomial).

The breaking or decomposition of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. Complete factoring is a three-step process: If at all possible, factor a GCF from the expression. Try to factor a trinomial if you can. Factor as many times as you can using a Difference Between Two Squares. Factorizing is the practice of expressing a number or other mathematical object as the sum of a number of other, typically smaller or more basic items of the same kind.

Given Data

8x² + 2x -3

Factorizing,

8x² + 2x -3 =0

8x² - 6x + 4x - 3 = 0

2x(4x -3) +1(4x - 3) =0
