Vertex at 8,1      and includes point 9,-1    <=====given

Vertex form :

y = a (x-8)^2 + 1

Plug in the point (9,-1)  to find 'a'

  -1 = a ( 9-8) + 1

    a = -2

Answer:

(x−h)2+(y−k)2=r2

Step-by-step explanation:

Standard form for the equation of a circle is (x−h)2+(y−k)2=r2. The center is (h,k) and the radius measures r units. To graph a circle mark points r units up, down, left, and right from the center.

Answer:

x = arccos(3/4) + 2πn where n = 0,1,2,3,4, ....

Step-by-step explanation:

We can solve the equation 4cos(x) + 3 = 6 by isolating the cos(x) term on one side of the equation.

4cos(x) + 3 - 3 = 6 - 3

4cos(x) = 3

cos(x) = 3/4

Now we can find the solutions of the equation by finding the values of x that make cos(x) equal to 3/4. Since -π < x < π, we can find the solutions in the range of -π < x < π.

x = cos^-1(3/4) + 2πn, where n is an integer

x = cos^-1(3/4) + 2πn, where n = 0, 1, 2, ...

The solutions are x= cos^-1(3/4) and x = cos^-1(3/4) + 2π, x = cos^-1(3/4) + 4π

Keep in mind that cos^-1(3/4) is the inverse cosine function or arccos(3/4) so the final solution is x = arccos(3/4) + 2πn where n = 0,1,2,3,4, ....

1% converts to the decimal form 0.01

0.01*800 = 8

Basically we move the decimal point two spots to the left

So the 800.0 becomes 8.000 or simply 8

Answer:

Step-by-step explanation:

Anything in percentage format can be expressed as a fraction by dividing by 100

Thus

[tex]\textrm{1\% }= \dfrac{1}{100}[/tex]

1% of 800 is found by multiplying 800 by the above fraction
[tex]\textrm{1\% of 800 } = 800\cdot \dfrac{1}{100} = 8[/tex]

Using the rate of the exponential growth to calculate the exponential function, the number of subscribers after 10 years is 3446

An exponential function is a function in which the variable appears in an exponent. It is of the form f(x) = aˣ, where a is a constant and x is the independent variable. The graph of an exponential function is a curve that increases or decreases at an increasing rate.

To solve this problem, we have to find the rate and then calculate the number subscribers after 10 years.

In a given exponential function;

A = P(1 + x)ⁿ

Since this is an exponential growth, we can calculate the rate as;

1 year = 250 subscriber

2 years = 3 * 250

rate = (250 / 750) * 100

rate = 30%

We can substitute the values into the formula and solve

A = 250(1 + 0.3)¹⁰

A = 3446.46

They are expected to have 3446 subscribers after 10 years

Step-by-step explanation:

0.3 =

In mathematics, the value for x is 9.38 in Example 1 and 11.40 in Example 2.

What are the value signifies?

The value in mathematics refers to the numerical representation of a quantity or concept. It represents the numerical magnitude of a mathematical expression, equation, or quantity.

For example, in the expression 2 + 3 = 5, the value of 2, 3, and 5 all represent specific numerical magnitudes. The value of a variable, such as x or y, can change depending on the context or equation it is used in, but it still represents a specific numerical value.

Values can be represented in different forms, such as integers, fractions, decimals, or real numbers, and they are used to perform mathematical operations and solve mathematical problems.

a) Example 1

AB  is a diameter

PQ is a chord

AO = 13

AO is perpendicular to PQ (2AP=AQ)

In Δ APO

[tex](AO)^2 =(AP)^2+ (PO)^2[/tex]

[tex](13)^2 = (9)^2 + X^2[/tex]

[tex]169 = 81 +X^2[/tex]

X^2 = 169-81

X^2 = 88

X = √88

X = 9.38

As a consequence, 9.38 is equal to x.

b) Example 2

LM = 18

KN = 7

LK = ?

LN = 9

In Δ LKN:

[tex]X^2 = (KN)^2 + (LN)^2[/tex]

[tex]X^2 = (7)^2 + (9)^2[/tex]

X^2 = 49 + 81

X^2 = 130

X =√ 130

X = 11.40

As a consequence, 11.40 is equal to x.

Answer: If 34,500 copies sold in the first month of release represent 9.8% of the number of copies sold to date, we can use this information to find the total number of copies sold to date. We can set up the equation as:

(34,500 copies) / (9.8%) = (Total number of copies sold to date)

To solve for the total number of copies sold to date, we can cross-multiply and divide by 0.098:

(34,500 copies) * (100%) / (9.8%) = (Total number of copies sold to date)

(34,500 copies) * (100/9.8) = (Total number of copies sold to date)

This simplifies to:

(34,500 copies) * 10.20408163 = (Total number of copies sold to date)

Total number of copies sold to date = 353878.163.

Rounding the answer to the nearest whole number we get:

Total number of copies sold to date = 353878.

So the book has sold 353878 copies to date.

230p – 1010 = 650p – 400 – p and 2.3p – 10.1 = 6.49p – 4 are the equations after rewriting their properties have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p.

As with other words like "equal," "equality," and "equate," the word "equa" at the start of the equation will sound familiar to you. Making things balance out is the theme of all these words. A statement of two quantities' equality is expressed by an equation.

You might still attempt to make the two sides equal even if the equation is not mathematical but rather, say, interpersonal. It might be simpler for two people to decide to remain together for a while if marriage is removed from the picture, for instance.

Given the equation 2.3p – 10.1 = 6.5p – 4 – 0.01p

When multiplied by 100, it becomes

230p – 1010 = 650p – 400 – p

And 6.5p - 0.01p = 6.49p

So, 2.3p – 10.1 = 6.49p – 4

Thus, 230p – 1010 = 650p – 400 – p and 2.3p – 10.1 = 6.49p – 4 are the equations after rewriting their properties have the same solution as 2.3p – 10.1 = 6.5p – 4 – 0.01p.

The rectangular bin has a depth of 20 feet.

A cuboid is a three-dimensional shape with rectangles on all sides. A cuboid has six faces, eight vertices, and twelve edges. All of the angles formed at a cuboid's vertices are right angles. The opposing edges are perpendicular to each other.

For the given situation,

A rectangular bin is in the shape of a cuboid.

Volume of the rectangular bin, V = 1200 cubic feet

Length of the rectangular bin ,l = 10 feet

Width of the rectangular bin,w = 6 feet

Let the height of the rectangular bin be h.

The depth of the box is found through the volume formula for a rectangular prism, which involves multiplying the length, width and depth. Knowing the volume when half-filled, and the length and width, we can calculate the box is 10 feet deep.

This problem deals with the concept of volume in mathematics. First, the formula for the volume of a rectangular prism (or a box) is length multiplied by width multiplied by height. In this case, we know that the box is half filled with grain and that the total volume of that grain is 200 cubic feet. So, if the box was filled completely, it would have a volume of twice that, or 400 cubic feet.

Now we know that the box's volume is 400 cubic feet and its length is 8 feet and width is 5 feet. So to find the height (which is what we're calling 'depth' in this case), we can use our volume formula. We divide the total volume by the product of the length and width (400/40) to find the height or depth, resulting in a depth of 10 feet.

Answer:

y = -1/2

Step-by-step explanation:

We are given the equation -10 - 8y = 2y - 5.

We want to solve this equation for y.

To do that, we need to isolate y on one side of the equation.

To start, add 10 to both sides.

-10 - 8y = 2y - 5

+10               +10

________________

-8y = 2y + 5

Subtract 2y from both sides.

-10y = 5

Divide both sides by -10.

y = -5/10

-5/10 can be simplified to -1/2.

Hence, y = -1/2.

The correct statement regarding the addition of the fractions is given as follows:

Answer:

x = √52

Step-by-step explanation:

Triangle PLM and JLK are connected together at L, which means that they share the same vertex L and therefore, the angle at L is the same for both triangles.

Since PLM and JLK are both triangles, we know that the sum of the angles in each triangle is always 180 degrees.

Let's call the angle at L as a. So we have:

a + (180-a) = 180

We know that PL = 6 and PM = 12, so we can use the Law of Cosines to find the value of the angle a:

c^2 = a^2 + b^2 - 2ab*cos(C)

where c is the hypotenuse, a and b are the other two sides and C is the angle opposite to c.

c = PL = 6

a = PM = 12

b = JL = 4

c^2 = 12^2 + 4^2 - 2124cos(a)

36 = 144 - 48cos(a)

cos(a) = (144 - 36)/48 = (108/48) = 9/4

a = arccos(9/4)

Now we know the measure of angle a and we can use it in the equation of the sum of angles in a triangle.

a + (180-a) = 180

We also know that JL = 4 and JK = x and we can use the Law of Cosines again to find the value of x.

x^2 = 4^2 + 6^2 - 246cos(a)

x^2 = 16 + 36 - 24(9/4)

x^2 = 52

x = √52
