Recall (or "define", if you're not familiar) the so-called ceiling and floor functions, or least/greatest integer functions, respectively; for any integer n,

• ceiling function:

[tex]\lceil x \rceil = n \text{ if } n-1 < x \le n[/tex]

• floor function:

[tex]\lfloor x \rfloor = n \text{ if } n \le x < n+1[/tex]

Let x and y be the two numbers Serena picks. She finds that

[tex]\lceil x \rceil \lceil y \rceil = 100[/tex]

[tex]\lfloor x \rfloor \lfloor y \rfloor = X[/tex]

Assume x and y are not integers. Let m and n be two integers such that m - 1 < x < m and n - 1 < y < n. Then

[tex]\lceil x \rceil \lceil y \rceil = mn = 100[/tex]

so m and n are divisors of 100. There's a finite number of distinct divisor pairs (m, n) to consider,

(± 1, ± 100), (± 2, ± 50), (± 4, ± 25), (± 5, ± 5)

whose sums can be one of

± 101, ± 99, ± 52, ± 48, ± 29, ± 21, ± 10, 0

Similarly,

[tex]\lfloor x \rfloor \lfloor y \rfloor = (m-1)(n-1) = 101 - (m + n) = X[/tex]

which is maximized if the sum m + n is negative; the largest of these is m + n = -101, so the maximum value of X is 101 + 101 = 202.

The reasoning for the case of either x or y, or both, being integers is nearly identical.

Answer:

this is too much, and I forgot how to do this

Answer:

  B

Step-by-step explanation:

Euler's formula tells you that ...

  cos(θ) +sin(θ)·i ≡ e^(i·θ)

__

So, for θ = 90° (= π/2 radians), this is ...

  cos(π/2) +sin(π/2)·i = 0 +i = i = e^(i·π/2) . . . . . matches choice B

Answer:

It's called the Natural Logarithm because so many processes in nature can be described mathematically using it.

For example:

1) The population of a colony of rabbits that reproduce at a constant rate

2) The decay rate of a charged capacitor

3) The decay rate of a radioactive isotope

4) The rate at which your money will grow if you apply an interest rate continuously over a period of time.

5) The population of seeds in a sun flower

6) etc.

Step-by-step explanation:

radius=6cm.

π=22 over 7

circumference=2πr

circumference=2×22 over7×6

circumference=51.04cm

Answer:

2 x 30   cm

Step-by-step explanation:

L x W = 60

(2x-12)(3x+9) = 60

 6x^2 -18x-168=0

use quadratic fromula to find   x = 7   or -4 (throw out)

the sides then become   ( using 7)    

 2   and 30   cm

Step-by-step explanation:

The function represented by the graph is

y = { x² + 6 , x < 3

        -x + 6 , x ≥ 3}

In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

According to the graph

When x < 3 then  y =  + 6

and, at x = 3 we get an open interval.

So, y = x² + 6 is valid for x < 3 not at x =3.

Also , y = -x + 6 is valid for x ≥ 3 and we get a close interval.

Thus, the function represented by the graph is

y = { x² + 6 , x < 3

        -x + 6 , x ≥ 3}

Answer:

pls refer to pic

well I am from India whats the time there now

7.25% of 38,000

10% = 3,800

5% = 1,900

1% = 380

0.50% = 190

0.25% = 95

1,900+380+380+95 = 2,755

38,000+2,755 = 40,755

[tex]2\sqrt{10}[/tex] is equivalent to the expression [tex]\sqrt{40}[/tex]

entire to mixed radical:

[tex]\sqrt{40} \\\sqrt{4\ x\ 10} \\2\sqrt{10}[/tex]

decimal value:

[tex]2\sqrt{10}=6.32....\\\sqrt{40}=6.32...[/tex]

Answer:

5, 6, 7

Step-by-step explanation:

let the 3 consecutive integers be n , n + 1 , n + 2 , then

n(n + 2) = n+ 1 + 29

n² + 2n = n + 30 ( subtract n + 30 from both sides )

n² + n - 30 = 0 ← in standard form

(n + 6)(n - 5) = 0 ← in factored form

equate each factor to zero and solve for n

n + 6 = 0 ⇒ n = - 6

n - 5 = 0 ⇒ n = 5

n > 0 , then n = 5

the 3 integers are 5, 5 + 1, 5 + 2 , that is

5, 6, 7

The domain is talking about the "range" of the horizontal axis therefore you will be focusing on the x-intercepts.

The answer will be All non-negative real numbers less than or equal to 18

because the x-intercepts lies at 0 and 18. The answer makes sense because the furthest you can go is 18 ft and the closest you could go is 0 ft. The "all non-negative real numbers" puts a restriction on the least distance it could travel so that means that it stops at 0 ft because if you go any further, you will end up in the negatives and it clearly states "non-negative".

Hey there!

To answer this question you have to plug in your values and do PEMDAS.
PEMDAS simply means

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction

WE CAN ANSWER THE EQUATION

1/4(c^3 + d^2)

= 1/4(-4^3 + 10^2)

= 1/4(-64 + 100)

= 1/4(-64) + 1/4(100)

= -16 + 25

= 9

OR

1/4(c^3 + d^2)

= 1/4(-4^3 + 10^2)

= 1/4(36)

= 9

Therefore, your answer is: 9

Good luck on your assignment & enjoy your day!

girl that is so easy, just look it up

Firstly this looks like translated log function graph

log1=0

As per graph the graph is pulled some inwards y axis but little bit

Usually log x leaves y axis at -1 but here it leaves at +2

So

y axis is moved upwards (+3)
