A baker uses the equation y= 3.5x to find the number of cups ,y, of milk he needs to make a number ,x, of tres leches cakes. What is the constant of proportionality between y and x?

Answer:

860.9 m³

Step-by-step explanation:

We can obtain the volume of the composite figure by subtracting the volume of cylinder from the volume of cuboid.

     l = 10 m

     w = 10 m

    h = 12 m

[tex]\sf \boxed{\text{ \bf Volume of cuboid = l *w * h}}[/tex]

                                    = 10 * 10 * 12

                                    = 1200 m³

      r = 3 m

      h = height of the cuboid = 12 m

    [tex]\sf \boxed{\text{\bf Volume of cylinder = $\pi r^2h$}}[/tex]

                                         = 3.14 * 3 * 3 * 12

                                         = 339.1 m³

Volume of composite figure = 1200 - 339.1

                                                = 860.9 m³

The ordering of the number is 6.286  , 6.628 , 6.826

According to the question we have been given three numbers which are

     6.826 , 6.628 and 6.286

We need to arrange in ascending order that is from least number to the greatest number.

when we arrange number in ascending order for decimal number we first look at the number before the decimal point then if they are all same then we look at the number after the decimal point. After the decimal point the first number is compared which is closest to the decimal point.

If we look into this question the number before decimal points are all same thus we will look the numbers after the decimal point. Therefore we will arrange according to the first  number after the decimal that is 8 , 6 and 2

Hence the ordering the number we get:

      6.286  , 6.628 , 6.826

Answer:

Step-by-step explanation:

b) Figure 1 is 2² = 4 (which is also 2x2=4 or if you count all the squares = 4)

Figure 2 is 3² = 9 (which is also 3x3=9 or if you count all the squares = 9 )

Figure 3 is 4² = 16 (which is also 4x4=16 or if you count all the squares = 16 )

Figure 4 is 5² =25(which is also 5x5=25 or if you count all the squares = 25)

Figure 5 is 6² = 36(which is also 6x6=36 or if you count all the squares =36)

c) Figure 1 add squares in a horizontal row which is your x-coordinate (2)

then add squares in a vertical row which is your y-coordinate (2)

so (x,y) = (2,2). Graph those points. Do the same for each and your line is a diagonal straight line traveling diagonally upward equally.

The right-angle triangle on the coordinate plane will be drawn. Then the third length of the right triangle will be 2√(a² - b²) units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

The right triangle ΔABC with legs AC and AB so that AC is 2a units long and leg AB is 2b units long.

We know that the angle ABC is a right angle which means 90°.

Then the third length of the right triangle will be

H² = P² + B²

(2a)² = (2b)² + B²

B² = 4a² - 4b²

B² = 4(a - b²)

B = 2√(a² - b²)

The right-angle triangle on the coordinate plane will be drawn.

Distance between the points A and B are equal to distance between points B and C.

So, The given triangle is isosceles.

And, The vertices on a coordinate are plot in figure.

Here,

The vertices of a triangle are A (0, 0), B (2a, b) and C (4a, 0)

We have to check the triangle is isosceles.

And, Plot the vertices on a coordinate grid to model the problem.

What is Isosceles triangle?

When two sides of a triangle are equal then the triangle is said to be isosceles triangle.

Now,

The vertices of a triangle are A (0, 0), B (2a, b) and C (4a, 0)

We have to check the triangle is isosceles.

For this we use distance formula and prove that the two sides of triangle are equal.

Distance between the points A (0, 0) and B (2a, b) is;

[tex]D_{AB} = \sqrt{(2a - 0)^2 + (b-0)^2} = \sqrt{4a^2+b^2}[/tex]

The translated and reflected function is:

g(x) = f(-x) - 3 = 3x + 1.

Here we want to transform a function f(x)=  -3x + 4.

First, remember that a vertical translation is written as:

g(x) = f(x) + N

Then a translation of 3 units down is written as:

g(x) = f(x) - 3

Now we want to do a reflection across the y-axis, this just changes the sign of the variable, so we get:

g(x) = f(-x) - 3

Now we replace the actual function f(x) by -3x + 4, we will get:

g(x) = -3*(-x) - 3 + 4 = 3x + 1

g(x) = 3x + 1

We conclude that the transformed function is 3x + 1.

Answer:

Pon tu tarea aquí para que podamos ayudarte con ella :)

The student walked 58.58 meters more than the total displacement from the starting point.

Given that a student walked 100 meters north, then 100 meters west.

We are required to find the number of meters, the student travelled more as compared to the total displacement from the starting point.

We have to find the distance from the starting point to ending point. We have to apply pythagoras theorem to find that distance.

Pythagoras theorem basically says that the square of hypotenuse of right angled triangle is equal to the sum of squares of base and perpendicular.

[tex]H^{2} =P^{2} +B^{2}[/tex]

In our case P is 100 meters and B is 100 meters and we have to find H from the formula given above.

[tex]H^{2} =100^{2} +100^{2}[/tex]

H=[tex]\sqrt{10000+10000}[/tex]

H=[tex]\sqrt{20000}[/tex]

H=141.42 meters

Difference=100+100-141.42

=200-141.42

=58.58 meters

Hence the student walked 58.58 meters more than the total displacement from the starting point.

   For the given parabola:

 We have the following data.

v = (-4,2)

f = (-4, 2.25)

d  = y = 1.75

We define what a parabola is

 The parabola is a geometric shape that is formed from the intersection of a vertical plane in a cone.

The canonical equation of a parabola is given by

(x - h)² = 4p(y - k)

The parabola is a quadratic function, it is composed of a vertex, or inflection point, a focus and a directrix.

  The parabola equation is:

y = x² + 8x + 18

y - 18  + 16 = x² + 8x + 16

y - 2 = x² + 2(4x) + 4²

y - 2 = (x + 4)²

This means that the vertex of this parabola is

v = (h, k)

v = (-4,2)

f = (-4, 2 + 1/4)

f = (-4, 2.25)

d = y = 2 - 1/4

d  = y = 1.75

first move the like terms to one side of the = sign. (its best to move the smaller x value to the bigger one.

When Olga turns 18, she will have $3032.89 in her account, which earned a monthly compound interest rate of 1.75%.

Compound interest refers to the amount of interest added on the principal amount plus interest. The formula of monthly compound interest is:

B = P(1 + r)^t

where B is the ending balance, P is the principal amount or original balance, r is the monthly interest rate in decimal form, and t is the number of months.

If Olga's uncle invested $2,000 in an account that was locked into a 1.75% interest rate, compounded monthly, using the formula, solve for the ending balance after 2 years.

B = P(1 + r)^t

B = 2000(1+ 0.0175)^24

B = $3032.89

For the given parabola, we have that:

a) The equation is: f(x) = -16(x - 0.75)² + 18.

b) The function is increasing at a rate of 12 feet per second, while the don't have the final point for the decrease, hence we cannot compute the average rate of change.

The equation of a quadratic function, of vertex (h,k), is given by:

y = a(x - h)² + k

In which a is the leading coefficient.

For this problem, the vertex is at (0.75,18), hence:

h = 0.75, k = 18.

f(x) = a(x - 0.75)² + 18.

When x = 0, y = 9, hence:

9 = 0.5625a + 18

a = -9/0.5625

a = -16.

Hence:

f(x) = -16(x - 0.75)² + 18.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

It is increasing between x = 0 and x = 0.75, in which f(0) = 9, f(0.75) = 18, hence:

r = 9/0.75 = 12.

The function is increasing at a rate of 12 feet per second, while the don't have the final point for the decrease, hence we cannot compute the average rate of change.

The recursive formula for the given sequence is a(n) = 2 a(n-1) - a(n-2) + 1

A recursive formula is an equation that express the nth term as a function of preceding term(s), i.e. as function of (n-1)th term, (n-2)th terms, and so on. Mathematically it can be written as:

a(n) = f(a(n-1), a(n-2), ..., a(1))

The given sequence: 1,3,6,10, . . .

Here a(1) = 1. Notice that:

a(2) = 3 = 1 + 2

a(3) = 6 = 3 + 3

a(4) = 10 = 6 + 4

Notice that the differences between terms increase by 1.

Further, we can write:

a(2) = 3 = 1 + (1 - 0) + 1

             = a(1) + a(1) + 1

             = 2a(1) + 1  

a(3) = 6 = 3 + (3 -1) + 1

             = a(2) + a(2) - a(1) + 1

             = 2a(2) - a(1) + 1

a(4) = 10 = 6 + (6 - 3) + 1

               = a(3) + a(3) - a(2) + 1

               = 2 a(3) - a(2) + 1

We can continue this recursive pattern to find a(n),

a(n) = 2 a(n-1) - a(n-2) + 1

We can find next term for n = 5:

a(5) = 2a(4) - a(3) + 1

       = 2. 10 - 6 + 1 = 15
