Using linear functions, the costs are given as follows:

For 4 hours, the difference is costs between the company that charges the most and the one that charges the least is of $15.

A linear function is modeled by:

y = mx + b

In which:

For Company A, we have two points on the column: (2, 33), (3, 49). Hence for one additional hour, the cost increased by $16, hence the slope is of 16 and:

A(x) = 16x + b.

When x = 2, A(x) = 33, hence we use it to find b as follows:

33 = 16(2) + b

b = 1.

Hence:

A(x) = 16x + 1.

Companies B and C have intercepts of 0, while the slopes are hourly costs, hence:

For 4 hours, the costs are given as follows:

The difference is:

72 - 57 = 15.

For 4 hours, the difference is costs between the company that charges the most and the one that charges the least is of $15.

Using the Fundamental Counting Theorem, it is found that the website would have 30,891,577,600 passwords.

It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]

For this problem, the first six spaces of the password are letters, and each can assume 26 values, hence the parameters are:

[tex]n_1 = n_2 = n_3 = n_4 = n_5 = n_6 = 26[/tex]

The last two spaces are composed by digits, and each can assume 10 values, hence the parameters are:

Hence the number of possible passwords is given by:

Answer: Yes

Step-by-step explanation:

If these lengths were to form a right triangle, then 51 and 68 would be the legs and 85 would be the hypotenuse.

[tex]51^2 +68^2 =7225\\\\85^2 =7225\\\\\therefore 51^2 +68^2 =85^2[/tex]

So, the side lengths form a right triangle.

The value of x will be 1099.8 when rounded it to the nearest decimals.

㏑(x-4)=7

Taking the exponential (e) both side, we get

[tex]e^{ln(x-4)} = e^{7}[/tex]

since 'e' and 'ln' cancels each other,

therefore

[tex]x-4 = e^{7}[/tex]

[tex]x = e^{7} + 4[/tex]                                                                                                  ..eq 1

Exponential 'e' is the Euler's number, which is a constant having the value of around 2.718281828459045235360.

so putting the value of 'e' in eq 1

[tex]x = (2.718)^{7} + 4[/tex]

x = 1095.838 + 4

x = 1099.838

Step-by-step explanation:

The equation of the line in point-slope form, with slope equal to 5/6 and passing through the point located at (22 , 12), is (y - 12) = 5/6(x - 22).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Using the point slope form, plug in the values to set up the equation.

(y - y1) = m(x - x1)

where m = 5/6 and (x1 , y1) = (22 , 12)

(y - 12) = 5/6(x - 22)

In slope-intercept form, the equation of the line is:

(y - 12) = 5/6(x - 22)

y - 12 = 5/6 x - 110/6

y = 5/6 x - 19/3

In standard form, the equation of the line is:

y = 5/6 x - 19/3

5/6 x - y = 19/3

Multiplying both sides by 6,

5x - 6y = 38

Step-by-step explanation:

The missing angle can be found by using the property '∠ sum of Δ'. The sum of the interior angles in a triangle is 180°.

The square symbol in the triangle represents a right angle, i.e. 90°.

Form an equation:

x +90° +48°= 180° (∠ sum of Δ)

x +138°= 180°

Applying the triangle sum theorem, the measures of the angles in △CBD are: m∠CDB = 90°; m∠BCD = 65°; m∠CBD = 25°

In △CAD, they are: m∠A = 65°; m∠ADC = 90°; m∠ACD = 25°

All interior angles of a triangle have a total sum of 180 degrees when added together, according to the triangle sum theorem.

Given:

Measure of angle C = 90 degrees

In △CAD, we have the following angle measures:

m∠A = 65° (given)

m∠ADC = 90° [right angle]

m∠ACD = 180 - 90 - 65 [triangle sum theorem]

m∠ACD = 25°

In △CBD, we have the following angle measures:

m∠CDB = 90° [right angle]

m∠BCD = 90 - m<ACD [complementary angle]

m∠BCD = 90 - 25

m∠BCD = 65°

m∠CBD = 180 - m∠BCD - m∠CDB [triangle sum theorem]

m∠CBD = 180 - 65 - 90

m∠CBD = 25°

In summary, applying the triangle sum theorem, the measures of the angles in △CBD are: m∠CDB = 90°; m∠BCD = 65°; m∠CBD = 25°

Answer:

The point of intersection is the number of gigabytes and the total cost when the two plans cost the same.

Step-by-step explanation:

Company A doesn't charge a fee "per gigabyte", there's just a flat fee and it is $100. Company B only charges a flat fee of $20, BUT there IS a "per gigabyte" charge. These two plans actually cost exactly the same when the customer uses 16 gigabytes.

By substitution, the solution of the system of equations, x - 2y + z = -4, -4x + y -2z = 1 and 2x + 2y - z = 10, is (x , y , z) = (2 , 1 , -4).

A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.

There are three methods that can be used to solve system of equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given three equations in x, y, and z,

x - 2y + z = -4     (equation 1)

-4x + y -2z = 1     (equation 2)

2x + 2y - z = 10     (equation 3)

Using the equation 1, find the value of one variable, lets say x, in terms of the other variables.

x - 2y + z = -4     (equation 1)

x = 2y - z - 4     (equation 4)

Substitute the equation 4 to equation 2 and 3 and find the value of another variable, lets say y, in terms of the other variable.

-4x + y -2z = 1     (equation 2)

-4(2y - z - 4) + y -2z = 1

-8y + 4z + 16 + y -2z = 1

-8y + y = 2z - 4z + 1 - 16

-7y = -2z - 15

y = -(2z + 15)/-7

y = (2z + 15)/7     (equation 5)

2x + 2y - z = 10     (equation 3)

2(2y - z - 4) + 2y - z = 10

4y - 2z - 8 + 2y - z = 10

4y + 2y = 2z + z + 10 + 8

6y = 3z + 18

y = (1/2)z + 3     (equation 6)

Substitute the value of y from equation 5 to equation 6 and solve for z.

y = (1/2)z + 3     (equation 6)

(2z + 15)/7 = (1/2)z + 3

2z + 15 = 7[(1/2)z + 3]

2z + 15 = (7/2)z + 21

2z - (7/2)z = 21 - 15

(-3/2)z = 6

z = -4

Substitute the value of z in either equation 5 or 6.

y = (1/2)z + 3     (equation 6)

y = (1/2)(-4) + 3

y = -2 + 3

y = 1

Finally, substitute the value of y and z to equation 4 and solve for x.

x = 2y - z - 4     (equation 4)

x = 2(1) - (-4) - 4

x = 2 + 4 -4

x = 2

Hence, the solution of the given system of equations is (x , y , z) = (2 , 1 , -4).
