In the given diagram, the value of x is 15

From the question, we are to determine the value of x

From one of the circle theorems, we have that

Opposite angles of a cyclic quadrilateral are supplementary.

Thus, in the diagram

5x + 7x = 180°

12x = 180°

x = 180°/12

x = 15

Hence, the value of x is 15

A pair of points which is perpendicular to line L is: D. (3, -5),(-6, 3).

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

For points A, we have:

[tex]Slope = \frac{3\;-\;(-6)}{3\;-\;(-9)}\\\\Slope = \frac{9}{12}[/tex]

Slope = 9/12.

For points B, we have:

[tex]Slope = \frac{6\;-\;(-2)}{-6\;-\;(-9)}\\\\Slope = \frac{8}{-3}[/tex]

Slope = -8/3.

For points C, we have:

[tex]Slope = \frac{3\;-\;(-6)}{3\;-\;(-5)}\\\\Slope = \frac{9}{8}[/tex]

Slope = 9/8.

For points D, we have:

[tex]Slope = \frac{3\;-\;(-5)}{-6\;-\;3}\\\\Slope = \frac{-8}{9}[/tex]

Slope = -8/9.

In Mathematics, the condition for perpendicularity of two lines is:

m₁ × m₂ = -1

9/8 × 8/9 = -1

Thus, points (3,−5) and (−6,3) are perpendicular to line L.

Equation for Determining the Number of Bacterial Cells

Initially, the count of bacterial cells = 4

It is given that the bacterial cell triples every month.

Hence, the equation for the count of bacterial cells after first month is,

a₁ = 4(3)

This count of 4(3) triples again in the second month.

So, after the second month, the equation for the count of bacterial cells is given by,

a₂ = 4(3)(3) = 4(3)²

Calculating the Count of Bacterial Cells For Each Month

Again, this count triples in the third month.

Therefore, the  equation for the count of bacterial cells after the third month becomes,

a₃ = 4(3)(3)(3) = 4(3)³

This count triples again in the fourth month and this process continues till 15 months.

A function assigns the value of each element of one set to the other specific element of another set. The correct option is A.

Suppose that the given function is

[tex]f:X\rightarrow Y[/tex]

Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is

[tex]f^{-1}: Y \rightarrow X[/tex]

such that:

[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]

(and vice versa).

It simply means that the inverse of 'f' is an undone operator, that takes back the effect of 'f'

Answer:

315 in.²

Step-by-step explanation:

Recall:

area of rectangle = length × width

area of triangle = base × height / 2

Base of prism: 9 in. × 9 in. = 81 in.²

4 sides of prism: 4 × 9 in. × 3 in. = 108 in.²

Lateral area of pyramid: 4 × 9 in. × 7 in. / 2 = 126 in.²

Total area = 81 in.² + 108 in.² + 126 in.² = 315 in.²

The resulting equation if Becca isolated x² in the first equation and then substituted it into the second equation is (9-y²) / 25 - y²/36 = 1

x² + y² = 9

x²/25 - y²/36 = 1

From (1)

x² = 9 - y²

substitute x² = 9 - y² into (2)

x²/25 - y²/36 = 1
