Dentro de cinco años mi abuelo tendrá el cuádruple de mi edad. Hace cinco años tenia siete veces mi edad¿que edad tenemos el y yo?

Answer:

9)  17 miles/hr

10)  7.14 miles

Step-by-step explanation:

See the attached worksheet.  Note the use of conversion factors.  In question 9 we want to convert minutes to hours.  We know there are 60 minutes/hr.  So we can set up a conversion factor in one of 2 ways:  (60 minutes/1 hr) or (1 hr/60 minutes).  Both are valid, and both are = 1, since the numerator and denominator are both equivalent.  This means we can invert a conversion factor and it is still = 1.  Since conversion facots are equal to 1, we can multiply them times anything, and the result is numerically the same (anything times 1 = anything) and only the units have changed.  For question 9, we want to convert miles/min to miles/hr.  I'll choose the conversion factor (60 min/1 hr), mostly because I like multiplication over division.  Note how the units cancel in the attachment, resulting in 17 miles/hr.  One may also use the factor (1hr/60min), but then a division is required.  Perfectly fine, but not my preferred route.

The same approach is used to answer question 10.  Again, note how he units cancel, leaving a number wth just the units desired,

N! also called N factorial is the product of all positive non-integers equal to or less than N or simply is the product of the Nth integer and all integers below it.

N! is represented as 1x2x3x4.......x n which is also equivalent to n x (n-1_x(n-2w)x(n-3)......x1.  Therefore the formula for N factorial is N! = n × (n - 1)!. For whole numbers, the factorial is a product of natural numbers till 1 of the values is equal to or less than whole numbers.

N is also used to represent the set of natural numbers up to infinity. Natural numbers include the values from till infinity, they can be represented like N=[1,2,3,4,5,6........].

When MN = 5x + 10, the lengths of MN, RS, and NP are 410, 400, and 320, respectively in this triangle .

A triangle is a polygon since it has three sides and three vertices. It is one of the basic geometric forms. The name given to a triangle with the vertices A, B, and C is Triangle ABC. A unique plane and triangle in Euclidean geometry are discovered when the three points are not collinear. Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.

We multiply by -3/2 to get rid of y and figure out the system of equations.

A mathematical assertion that has an "equal to" symbol between two expressions with equivalent values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including straight, quadratic, cubic, and others.

So, we have:

9x+3/4y=6 and 2x+1/2y=9

By removing y, we must solve a system of equations.

Therefore, we will first make the y-coefficient equal but with the opposite sign.

In the first equation, the y-coefficient is 3/4

The coefficient of y in equation two is half.

LCM: 3/4 and 1/2 = 3/2
To maintain the same coefficient of y, multiply the second equation by -3/2.

-3/2*2x-3/2*1/2y = -3/2*9

-3x-3/4y = -27/2

9x+3/4y = 6

Combine the two equations and get rid of the y variable.

-3x+9x = -27/2+6

6x = -15/2

x = -5/4

Therefore, we multiply by -3/2 to get rid of y and figure out the system of equations.

Brooklyn could calculate how many arithmetic problems she completed and how many pages she read using the equations x = 2y and 2x + 3y = 70.

let

number of math problems Brooklyn solved = x

number of pages she read = y

Time to solve each math = 2 minutes

Time to read each page = 3 minutes

Brooklyn read twice as many pages as there were arithmetic problems to be done.

x = 2y

2x + 3y = 70

Substitute x = 2y into

2x + 3y = 70

2(2y) + 3y = 70

4y + 3y = 70

7y = 70

divide both sides by 7

y = 70/7

y = 10

Recall,

x = 2y

x = 2(10)

x = 20

The value of the integration of the expression [tex]$$\int x^3+\frac{1}{x^{0.5}} d x$$[/tex] will be  [tex]\frac{1}{4} x^4+2 x^{0.5}+C[/tex]

[tex]$$\int x^3+\frac{1}{x^{0.5}} d x$$[/tex]

Split the single integral into multiple integrals.

We will get: [tex]$$\int x^3 d x+\int \frac{1}{x^{0.5}} d x$$[/tex]

By the Power Rule, the integral of x^3 with respect to x is (1/4)x^4.

[tex]\frac{1}{4} x^4+C+\int \frac{1}{x^{0.5}} d x[/tex]

Let u=x^{0.5}.

Then [tex]d u=\frac{0.5}{x^{0.5}} d x[/tex],

So [tex]$\frac{x^{0.5}}{0.5} d u=d x$[/tex].

Now, we will rewrite the above using u and du.

Let u=x^{0.5}.

Finding the value of (du/dx)

Differentiate x^{0.5}.

[tex]\frac{d}{d x}\left[x^{0.5}\right][/tex]

Differentiate using the Power Rule which states that [tex]$\frac{d}{d x}\left[x^n\right]$[/tex] is n x^{n-1} where n=0.5.

We will get: 0.5 x^{-0.5}

Simplify.

Rewrite the expression using the negative exponent rule

[tex]b^{-n}=\frac{1}{b^n}\\0.5 \frac{1}{x^{0.5}}[/tex]

Combine 0.5 and [tex]\frac{1}{x^{0.5}}[/tex] we will get [tex]\frac{0.5}{x^{0.5}}[/tex]

Rewrite the problem using u and du.

We will get it as:

[tex]\frac{1}{4} x^4+C+\int 2 d u[/tex]

Apply the constant rule, we will get: [tex]\frac{1}{4} x^4+C+2 u+C[/tex]

Simplifying we will get it as: [tex]\frac{1}{4} x^4+2 u+C[/tex]

Replace all occurrences of u with x^{0.5}.

a) The quadratic function g(x) = 2f(x-4) + 5 is defined as a transformed version of the original quadratic function f(x). The transformation applied to f(x) is a horizontal shift of 4 units to the left and a vertical shift of 5 units upward. This can be observed from the fact that x is replaced with (x-4) in the function g(x). The function is also scaled by a factor of 2.

How does a quadratic function work?

f(x) = ax2 + bx + c, where a, b, and c are numbers and an is not equal to zero, is a quadratic function. A parabola is the shape of a quadratic function's graph. Although the "width" or "steepness" of a parabola can vary as well as its direction of opening, they all share the same fundamental "U" form.

b) The turning point of the quadratic function f(x) is (-3, 2). To find the turning point of g(x), we must first apply the horizontal shift of 4 units to the left to the x-coordinate, and then apply the vertical shift of 5 units upward to the y-coordinate.

The turning point of g(x) is (-3+4, 2+5) = (1,7)

So, the turning point of the transformed function g(x) is (1,7)

We can see that the transformation of g(x) moves the turning point of f(x) to the right and up, as expected from the transformation.

Step-by-step explanation:

Simplify the following:

The gcd of 24 and -6 is 6, so (24 x^6 y^3)/(-6 x^3 y) = ((6×4) x^6 y^3)/((6 (-1)) x^3 y) = 6/6×(4 x^6 y^3)/(-x^3 y) = (4 x^6 y^3)/(-x^3 y):

(4 x^6 y^3)/(-1 x^3 y)

Combine powers. (4 x^6 y^3)/(-x^3 y) = (4 x^(6 - 3) y^(3 - 1))/(1 (-1)):

(4 x^(6 - 3) y^(3 - 1))/(-1)

Any shape with 3 sides and three points is a polygon. The fundamental form of geometry is this. The corners of the triangular Triangle ABC are A, B, and C. When four parts are not collinear in a geometric shape, a single plane plus triangle are produced. As triangles have three sides as well as a top right corner, they are included in polygons.

y = x^2 represents a nonlinear function.

A linear function has the form of y = mx+b where m and b are constants and x is variable, the graph of a linear function is always a straight line. A nonlinear function is any function that is not linear, the graph of a nonlinear function is not a straight line.

y = x^2 is nonlinear because the variable x is squared, a quadratic function and its graph is a parabola.

y=2x is a linear function and its graph is a straight line, increasing linearly with x.

y = x is also a linear function and its graph is also a straight line, increasing linearly with x.

y = x+2 is a linear function and its graph is also a straight line with a y-intercept of 2, increasing linearly with x

So, y = x^2 represents a nonlinear function, and it is the correct answer.
