Which of the following could be the equation of the function below?

Answer:

36 ft

Step-by-step explanation:

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.

Answer: 36 ft

Step-by-step explanation:

Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.

[tex]\frac{LeftLeg(large)}{LeftLeg(small)}= \frac{BaseLeg(large)}{BaseLeg(small)}[/tex]

                  [tex]\frac{x}{3}= \frac{48}{4}[/tex]

Cross multiply: x(4) = 3(48)

solve for x:        ÷4     ÷4    

                          x    =  3(12)

                                =  36

The SSE for the data set is:  24

The data points are given by:

        (3,6),(6,2),(9,10)

The data points are as follows:

when x=3   y=6

when x=6   y=2

and when x=9   y=10

Also, the line of best fit is as follows:

[tex]y=\dfrac{2}{3}x+2[/tex]

The SSE( sum of square for error ) is calculated as follows:

when x=3

from the line of best fit we have: y=4

when x=6

then y=6

when x=9

then y=8

when x=3        6-4= -2

when x=6       2-6= -4

and when x=9      10-8=2

Hence, the square of these difference quantity is:

(-2)²=4

(-4)²=16

and (2)²=4

Hence, the sum of these square quantity is: 4+16+4=24

Hence, the SSE of data is:  24

Step-by-step explanation:

We are given the co-ordinates,

x : -2, -1, 0, 1, 2

y : 8, 5, 2, -1, -4

According to the graph, we see that this function represents a straight line.

The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.

So, taking any two points we will find the equation of the straight line.

Consider, (0,2) and (1, -1). Now, slope is given by,

m = [tex]\frac{-1-2}{1-0}[/tex]

i.e. m = -3

Now, we will find the y-intercept of this equation using (0,2) and m = -3,

i.e. y = -3x + c

i.e. 2 = c

Hence, the equation of the straight line is y = -3x + 2.

Step-by-step explanation:

[tex]\int 3x(x^2+3)^4 \ dx[/tex].

It is apparently obvious we could expand the bracket and integrate term-by-term. This method would work but is very time consuming (and you could easily make a mistake) so we use a different method: integration by substitution.

Integration by substitution involves swapping the variable [tex]x[/tex] for another variable which depends on x: [tex]u(x)[/tex]. (We are going to choose [tex]u[/tex] for this question).

The very first step is to choose a suitable substitution. That is, an equation [tex]u=f(x)[/tex] which is going to make the integration easier. There is a trick for spotting this however: if an integral contains both a term and it's derivative then use the substitution [tex]u=\text{The Term}[/tex].

Your integral contains the term [tex]x^2 + 3[/tex]. The derivative is [tex]2x[/tex] and (ignoring the constants) we see [tex]x[/tex] is also in the integral and so the substitution [tex]u=x^2+3[/tex] will unravel this integral!

Step 2: We must now swap the variable of integration from x to u. That means interchanging all the x's in the integrand (the term being integrated) for u's and also swapping (dx" to "du").

[tex]u=x^2+3 \Rightarrow \frac{du}{dx}=2x \Rightarrow dx = \frac{1}{2x} du[/tex]

Then,

[tex]\int 3x(x^2+3)^4 \ dx = \int 3x \cdot u^4 \cdot \frac{1}{2x} du = \int \frac{3}{2}u^4\ du[/tex].

The substitution has made this integral is easy to solve!

[tex]\int \frac{3}{2}u^4\ du= \frac{3}{10}u^5 + C[/tex]

Finally we can substitute back to get the answer in terms of x:

[tex]\int 3x(x^2+3)^4 \ dx = \frac{3}{10}(x^2+3)^5+C[/tex]

The equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex].

Let's denote the entrance fee as E (in dollars) and the cost of each slice of pizza as P (also in dollars). Given the problem, we can write the following equations based on the given information:

After having 1 slice of pizza, the total cost is $6:

[tex]\(E + 1 \times P = 6\)[/tex]

After having 2 more slices of pizza (total 3 slices), the total cost is $10:

[tex]\(E + 3 \times P = 10\)[/tex]

To find the equation that represents the total cost (y) after buying x slices of pizza (let's call it C(x), we need to generalize the pattern observed in the given equations.

Notice that the entrance fee remains constant regardless of the number of slices of pizza bought. So, we can write the equation as:

[tex]\[ E + x \times P = C(x) \][/tex]

Substituting the values given in the problem:

[tex]\[ C(x) = E + x \times P \][/tex]

So, the equation representing the total cost after buying x slices of pizza

is [tex]\( C(x) = E + x \times P \)[/tex]. This equation gives the total cost (y) as a function of the number of slices of pizza bought (x).

Answer:

BC = 6.7 cm (rounded to nearest tenth)

Explanation:

Given: ABC is a right triangle with right angle C as shown below.

Side AB=18 cm and m∠A=22°.

Using Sine ratio in triangle ABC to find BC.

Sine ratio is defined as the ratio of the opposite side of a right triangle to the hypotenuse.

i.e

[tex]\sin A = \frac{Opposite side}{Hypotenuse side}[/tex]

Let BC = x (opposite side) and AB = 18 cm(Hypotenuse side)

then;

 [tex]\sin 22^{\circ} = \frac{x}{18}[/tex]

[tex]0.37460659341 = \frac{x}{18}[/tex]

Multiply both sides by 18 we get;

[tex]x = 0.37460659341 \times 18 = 6.74291868[/tex]

therefore, value of BC (nearest tenth place) is, 6.7 cm

The student that solved at a rate of 28 per minutes was Logan

Answer:

Logan

Answer:

Logan solved problems at a rate of 28 problems per minute.

Step-by-step explanation:

To find the number of problems per minute that a person solved, you will divide the number of problems that they solved by the number of minutes that they took.

Murray:

58 problems in 2 minutes,

58 / 2 = 29

He solved problems at a rate of 29 problems per minute.

Kris:

78 problems in 3 minutes,

78 / 3 = 26

He solved problems at a rate of 26 problems per minute.

Logan:

84 problems in 3 minutes,

84 / 3 = 28

He solved problems at a rate of 28 problems per minute.

Since you found that Logan solved problems at a rate of 28 problems per minute, Logan is the student that solved problems at a rate of 28 per minute.

What is Algebraic expression ?

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

given variable is given as c therefore, the translation of the given equation  Five more than the quotient of a number and 7 is equal to 8 will be :

We have the supplementary angles.

The sum of the measures of the two Supplementary Angles is 180°.

Therefore we have the equation:

13x = 143      divide both sides by 13

The perimeter of the rectangle is 42m.

To find the perimeter of the rectangle, we need to know the lengths of its sides. From the given information, we know that the area of the rectangle is 108m^2 and its diagonal is 15m. We can use this information to find the lengths of the sides.

Let the length of the rectangle be 'l' and the width be 'w'.
Given, lw = 108 and sqrt(l^2 + w^2) = 15.
Squaring both sides of the second equation, we get l^2 + w^2 = 225.
Since lw = 108, we can solve the quadratic equation l^2 - 108l + 225 = 0 to find l. In this particular case, the quadratic factors as (l - 9)(l - 12) = 0, so l = 9 or l = 12.
Substituting the values of l in the equation lw = 108, we find w = 12 or w = 9.
Since the perimeter is the sum of all the sides, the perimeter of the rectangle is (2l + 2w) = (2 * 9 + 2 * 12) = 42m.
