0     -2

3     10

Answer:

A general way of explaining this is

Suppose that we have a given property (or a pattern if we are working with a series of numbers):

Now, if that property is true, for example, for the numbers 1, 2, 3... etc.  Then we can suppose that the property is also true for an unknown number N.

Now, if using the hypothesis that the property is true for N, we can prove that the property is also true for N + 1, then we actually proved that the property is true for all the set.

We actually can use any set, not only the natural numbers.

For example, we can use the set of the even numbers {2, 4, 6, 8....}, suppose that the property is true for a random number N, that is even, and then see if using that hypothesis we can prove that the property is also true for the next number in the set; N + 2.

Answer:

y = (x - 8)² - 47

Step-by-step explanation:

x² - 16x + 17 = 0

x² - 16x = -17

(-16) / 2 = -8

-8² = 64

x² - 16x + 64 = -17 + 64

(x - 8)² = 47

y = (x - 8)² - 47

Answer:

a...is wrong because it doesnt have a common denominator ..and its not a rational exponent .

11/12=0.916

in second one denominators are common and it is a rational exponent .

so the answer is b..

2/12=1/6

9/12=3/4

as you can see the denominator are common and its a rational exponent .

Answer:

Bacterial population at the time of 10 hours = 1040000

Step-by-step explanation:

Let the function that defines the bacterial population after 'x' hours is,

p(x) = a(b)ˣ

Where a = Initial population

And 'x' = Duration or time

Since bacterial population is getting doubled every hour,

2a = a(b)¹

b = 2

Therefore, function will be,

p(x) = a(2)ˣ

From the graph attached,

Point (5, 32500) lies on the graph of the function.

32500 = a(2)⁵

a = [tex]\frac{32500}{32}=1015.625[/tex]

Therefore, the function will be,

p(x) = 1015.625(2)ˣ

For x = 10 hours,

p(10) = 1015.625(2)¹⁰

        = 1040000 bacteria

Answer:

p = -6.5

Step-by-step explanation:

Given:

Solving for p:

Option 2 is correct in the list

Composite functions are multiple functions combined to form another function.

The value of the composite function (p - q)(2) is 5

To find (p - q)(2), we make use of the following composite function formula:

[tex](p - q)(x) = p(x) - q(x)[/tex]

Substitute 2 for x in the above formula

[tex](p - q)(2) = p(2) - q(2)[/tex]

From the table entries, we have:

[tex]p(2) =3[/tex]

[tex]q(2) = -2[/tex]

So, the equation becomes

[tex](p - q)(2) = 3 -- 2[/tex]

Rewrite the above equation as:

[tex](p - q)(2) = 3 + 2[/tex]

Take the sum of 3 and 2

[tex](p - q)(2) = 5[/tex]

Hence, the value of (p - q)(2) is 5

712,402,207

Step-by-step explanation:

;)

Answer: 711,142,207

Step-by-step explanation:

Answer:

  no

Step-by-step explanation:

The circumference of a table is ...

  C = πd = π(180 cm) ≈ 565.5 cm

At 70 cm/guest, a table will accommodate ...

  565.5 cm/(70 cm/guest) = 8.08 guests

At 8 guests per table, the available 18 tables will accommodate ...

  (18 tables)(8 guests/table) = 144 guests

There is not enough space at 18 tables for 145 guests.

Answer:

No, it's not.

Step-by-step explanation:

First, find the circumference of the table:

C = 2πr

= 2 × 22/7 × 180/2

NOTE: Diameter/2 is equal to the radius because half of Diameter is a radius.

= 44/7 × 90

= 3,969/7

= 565.71 approximately 566cm²

Next, find how many guests can occupy a table:

566/70 = 8.08 approximately 8 guests.

Now, how many guests will be in 18 tables?

18 × 8 = 144 guests, but we need 145 guests, so it is not enough.

Answer:

Step-by-step explanation:

Indian books = 4x - 15

Total books = 12x + 5x + 4x + 4x - 15  {add like terms}

Step-by-step explanation:

Width=x

Length=x+2

X+x+x+2+x+2=74

4x+4=74

4x=70

x=17.5

A=LW

A=17.5*19.5

A=341.25in²

Answer:

422 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the upper cuboid + surface area of lower cuboid) - 2(base area of the lower cuboid)

Surface area of composite figure = [tex] (2(lw + lh + hw)) + (2(lw + lh + hw)) - 2(l*w) [/tex]

Upper cuboid has the following dimensions:

[tex] l = 4, w = 3, h = 8 [/tex]

Lower cuboid has the following dimensions:

[tex] l = 10, w = 7, h = 5 [/tex]

Plug these values into the formula

Surface area of composite figure

[tex] = (2(4*3 + 4*8 + 8*3)) + (2(10*7 + 10*5 + 5*7)) - 2(4*3) [/tex]

[tex] = (2(12 + 32 + 24)) + (2(70 + 50 + 35)) - 2(12) [/tex]

[tex] = (136 + 310) - 24 [/tex]

[tex] = 446 - 24 = 422 [/tex]

Surface area of composite figure = 422 cm²

Answer:

Step-by-step explanation:

5x - 8 = 16 -3x

8x - 8 = 16

8x = 24

x = 3

AC= 5(3) - 8 = 15 - 8 = 7

CD= 16 - 3(3) = 16 -9 = 7

7 + 7 = 14 = AD

The value of x and AD such that C is the midpoint of AD is 3 and 14 respectively.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

Given the line segment AD with mid-point C

So,

AC = CD

5x - 8 = 16 - 3x

8x = 16 + 8

x = 3

So,

AD = 5x - 8 + 16- 3x

AD = 2x + 8

AD = 2(3) + 8 = 14

Hence "The value of x and AD such that C is the midpoint of AD is 3 and 14 respectively".

Answer:

15

Step-by-step explanation:

Use the pythagorean theorem.

A² + B² = C²

In this case, A = 8, B is unknown, and C = 17. B is the side that we want to calculate.

8² + B² = 17²

64 + B² = 289

B² = 225

B = √225 = 15

Literally, irrational numbers are numbers that cannot be expressed as simple fractions. Some irrational numbers between 7 and 10 are 7.4833,7.9372,8.3666,8.4852,9.4868.

Given that

[tex]Min = 7[/tex]

[tex]Max = 10[/tex]

There are several ways to generate the irrational numbers between the given range.

One of the ways is as follows:

First, we list the pairs of relatively prime integers between the given range.

They are:

[tex]x = \{(7,8),(7,9),(7,10),(8,9),(9,10)\}[/tex]

Calculate the product

[tex]x = \{56,63,70,72,90\}[/tex]

Take the positive square root of the numbers to generate some irrational integers

[tex]x = \{\sqrt{56},\sqrt{63},\sqrt{70},\sqrt{72},\sqrt{90}\}[/tex]

[tex]x = \{7.4833...,7.9372....,8.3666...,8.4852....,9.4868....\}[/tex]
