Step-by-step explanation:

The value of x in the circle is 1.

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

if a tangent and a chord are drawn from a point outside a circle, and the point of intersection of the tangent and the circle is labeled as point P, then the length of the tangent squared is equal to the product of the lengths of the two segments of the chord:

Now,

From the figure,

(2x - 9)² = 27 (2x + 2)

We can start by simplifying the left-hand side of the equation:

(2x - 9)² = 27 (2x + 2)

4x² - 36x + 81 = 54x + 54

Now we can move all the terms to one side and simplify:

4x² - 90x + 27 = 0

Next, we can use the quadratic formula to solve for x:

x = (-b ± √(b² - 4ac)) / 2a

where a = 4, b = -90, and c = 27.

Plugging in the values:

x = (-(-90) ± √((-90)² - 4(4)(27))) / 2(4)

x = (90 ± √(8100 - 432)) / 8

x = (90 ± √(7668)) / 8

x = (90 ± √(447)) / 8

x ≈ 11.16 or x ≈ 1.09

Rounding to a whole number.

x = 1

Therefore,

The value of x in the circle is 1.

Answer:

x=√65 and x=-√65

Step-by-step explanation:

Givn the expression 2x^2 - 9 = 121

Add 9 to both sides

2x^2 - 9 + 9 = 121 + 9

2x^2 = 130

Divide both sides b 2

2x^2/2 = 130/2

x^2 = 65

x = ±√65

x=√65 and x=-√65

Answer:

[tex](x-4)^2+(y-7)^2=125[/tex]

Step-by-step explanation:

1) Find the radius

To find the radius of the circle, use the distance formula for the points (4,7) and (-7,9)

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (4,7) and (-7,9)

[tex]d=\sqrt{(-7-4)^2+(9-7)^2}\\d=\sqrt{(-11)^2+(2)^2}\\d=\sqrt{121+4}\\d=\sqrt{125}[/tex]

Therefore, the radius of the circle is [tex]\sqrt{125}[/tex] units.

2) Plug all data into the circle equation

Equation of a circle (not centred at the origin):

[tex](x-h)^2+(y-k)^2=r^2[/tex] where the centre is [tex](h,k)[/tex]

Plug in the point (4,7) as (h,k)

[tex](x-4)^2+(y-7)^2=r^2[/tex]

Plug in the radius [tex]\sqrt{125}[/tex]

[tex](x-4)^2+(y-7)^2=(\sqrt{125}) ^2\\(x-4)^2+(y-7)^2=125[/tex]

Pyramid formula: V= LWH/3

Step-by-step explanation:

Answer:

336

Step-by-step explanation:

The figure shown is a triangular prism

The volume of a triangular prism can be calculated by using this formula

[tex]V=ah[/tex]

where a = area of base and h = height

we are already given the height ( 8 ft ) so all we need to find is the area of the base

Because this is triangular prism the base will be a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

The base length of this particular triangular prism is 12 ft and the height of the base is 7 ft

That being said we plug in the values into the formula

[tex]A=\frac{12*7}{2} \\12*7=84\\\frac{84}{2} =42[/tex]

So we can conclude that the area of the base is 42 ft²

Now to find the volume

Using the formula V = ah

* plug in the values *

V = 42 * 8

42 * 8 = 336

Therefore the volume of the triangular prism is 336ft³

The percentage rate of decay per year is of 5.19%.

The function  showing the mass of the sample remaining after t is [tex]A(t) = 520(0.9481)^t[/tex]

Step-by-step explanation:

Exponential equation of decay:

The exponential equation for the amount of a substance is given by:

[tex]A(t) = A(0)(1-r)^t[/tex]

In which A(0) is the initial amount and r is the decay rate, as a decimal.

Every 13 years, its mass decreases by half.

This means that [tex]A(13) = 0.5A(0)[/tex]. We use this to find r. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]0.5A(0) = A(0)(1-r)^{13}[/tex]

[tex](1-r)^{13} = 0.5[/tex]

[tex]\sqrt[13]{(1-r)^{13}} = \sqrt[13]{0.5}[/tex]

[tex]1 - r = (0.5)^\frac{1}{13}[/tex]

[tex]1 - r = 0.9481[/tex]

[tex]r = 1 - 0.9481[/tex]

[tex]r = 0.0519[/tex]

The percentage rate of decay per year is of 5.19%.

The initial mass of a sample of Element X is 520 grams

This means that [tex]A(0) = 520[/tex]. So

[tex]A(t) = A(0)(1-r)^t[/tex]

[tex]A(t) = 520(1-0.0519)^t[/tex]

[tex]A(t) = 520(0.9481)^t[/tex]

The function  showing the mass of the sample remaining after t is [tex]A(t) = 520(0.9481)^t[/tex]

Step-by-step explanation:

8x10=80

because, lxw

l= length

w= width

Answer:

80

Step-by-step explanation:

im not trying to copy the answer above, im just going to say why its 80

so firstly we have the known dimensions of 10 by 8, so in this case we have 10 rows that each contain 8 units

we can then multiply the 8 units of one row, by the amount of rows there are total (in this case 10) to get the total unit count, or area

8 * 10 = 80

(NOTE: you can use the Asterisk (*) as a multiplication mark as to not get it confused with x as in the variable, as with slash (/) for dividing)

Answer:

15595 bacteria will be present after 13 hours.

Step-by-step explanation:

Continuous population growth:

The continuous population growth model, for the population after t hours, is given by:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial population and r is the growth rate.

Started with 5000 bacteria

This means that [tex]P(0) = 5000[/tex]

So

[tex]P(t) = 5000e^{rt}[/tex]

After three hours it grew 6500 bacteria:

This means that [tex]P(3) = 6500[/tex]. We use this to find r.

[tex]P(t) = 5000e^{rt}[/tex]

[tex]6500 = 5000e^{3r}[/tex]

[tex]e^{3r} = \frac{65}{50}[/tex]

[tex]\ln{e^{3r}} = \ln{\frac{65}{50}}[/tex]

[tex]3r = \ln{\frac{65}{50}}[/tex]

[tex]r = \frac{\ln{\frac{65}{50}}}{3}[/tex]

[tex]r = 0.0875[/tex]

So

[tex]P(t) = 5000e^{0.0875t}[/tex]

How many bacteria will be present after 13 hours?

This is P(13). So

[tex]P(13) = 5000e^{0.0875*13} = 15594.8[/tex]

Rounding to the nearest whole number

15595 bacteria will be present after 13 hours.

The appropriate description of the graph is as follows

1. The demand for health supplements in Oklahoma A: increases slowly.

2. The demand for health supplements in Oklahoma B: Decreases quickly.

3. The demand for health supplements in Oklahoma for C: Increases quickly.

4. The demand for health supplements in Oklahoma for D: decreases slowly.

To interpret lines on a graph, we must first note that those lines mean a number of things but ultimately, the tell or show is the relationship between two or more variables.

In the case of the Oklahoma graphs, we know that the lines represents the deman for health supplements. However, what we don't know are those factors that are causing the demands to increase or decrease.
