Evaluate - x - y - z when x = - 8, y = 6 and z = -4.

Answer:

Step-by-step explanation:

Start with this equation where 17 is the base, x is the power that 17 must be raised to. Then 2 is the result.

17^x = 2                      Take the log of both sides

log(17^x) = log(2)        Take the x outside the brackets

x log(17) = log(2)         Divide by log 17

x = log(2)/log(17)         Find the values for log  2 and log 17

log(2) = 0.3010

log(17) = 1.230

x = .3010/1.230

x = .2446

Step-by-step explanation:

f(x+1) = 2(x+1)^2 + 1

Answer:

Step-by-step explanation:

Given the speed of Stephano’s marble is represented by the equation

f = 2.25s, where f is the distance in feet and s is the time in seconds.

To get the marble that will reach the 6-foot mark sooner, we will substitute the value of f = 6 and calculate the value of s as shown:

f = 2.25s

6 = 2.25s

s = 6/2.25

s = 2.67secs

Hence the 6 foot marble will reach after 2.67secs

Answer:

The answer is B.

Step-by-step explanation:

The answer is B, because if you have a vertical line, it is undefined. And also, it is on the x-axis, therefore it would be x = 4.

Answer

b. x=4, undefined

Step-by-step explanation:

the x value constantly stays at 4 because it’s a straight vertical line. there’s no slope because it’s straight up and down.

Answer:

22/35

Step-by-step explanation:

Simplify the following:

((1 + 4/7)×2)/5

((1 + 4/7)×2)/5 = ((1 + 4/7)×2)/5:

((1 + 4/7)×2)/5

Put 1 + 4/7 over the common denominator 7. 1 + 4/7 = 7/7 + 4/7:

((7/7 + 4/7) 2)/5

7/7 + 4/7 = (7 + 4)/7:

(((7 + 4)/7)×2)/5

7 + 4 = 11:

(11/7×2)/5

11/7×2 = (11×2)/7:

((11×2)/7)/5

((11×2)/7)/5 = (11×2)/(7×5):

(11×2)/(7×5)

7×5 = 35:

(11×2)/35

11×2 = 22:

Answer: 22/35

Hey there!

=> 59 + x = 24

=> x = 24 - 59

=> x = -35

Therefore, 59 + (-35) = 24

Answer:

[tex]\boxed{\sf{x=-35}}[/tex]

Step-by-step explanation:

A subtraction property of equations is the subject of this problem.

For the correct answer, you need to isolate x from one side of the equation.

59+x=24

First, switch sides.

x+59=24

Then, subtract by 59 from both sides.

[tex]\sf{x+59-59=24-59}[/tex]

Solve.

[tex]\sf{24-59=-35}[/tex]

[tex]\boxed{\sf{x=-35}}[/tex]

Therefore, the solution is x=-35, which is our answer.

Answer:

probably -9 degrees

Step-by-step explanation:

The least common multiple that is divisible by both a and b is the smallest positive integer. The number of times Ram, Hari and Shyam will meet in 180 days is 30 times.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

Given that Ram, Hari and Shyam go for a swim after a gap of every 1 day, 2 days and 3 days respectively. Therefore, the number of day after which all three together will meet can be found by taking the LCM.

Since the LCM of the 1, 2 and 3 are 6. Therefore, the three of them will meet after every 6 days.

Thus, if they all meet today then within 180 days, the number of times they meet is,

Number of times they meet = 180 days/6 = 30

Hence, the number of times Ram, Hari and Shyam will meet in 180 days is 30 times.

Answer:

a) 676, 1296

b) 17576, 46656

c) 456976, 1679616

Step-by-step explanation:

firstly we know that there are 26 letters in the alphabet.

there are 26 ways of choosing the first character and 26 ways choosing the second character,

Therefore, the possible number of domains with two leeter is;

n = 26²

= 26 × 26

= 676

now when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore the possible number of domains with two characters is;

n = 36²

= 36 × 36

= 1296

b)

there are 26 ways of choosing each character

therefore, the possible number of domains with three letters is

n = 26³

= 26 × 26 × 26

= 17576

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore , the possible number of domains with three characters is;

n = 36³

= 36 × 36 × 36

= 46656

c)

there are 26 ways of choosing each character, therefore the possible number of domains with four letters is;

n = 26⁴

n = 26 × 26 × 26 × 26

n = 456976

when the digits are allowed, there are 26 + 10 = 36 characters to be used in total

therefore, the possible number of domains with four characters is;

n = 36⁴

n = 36 × 36 × 36 × 36

= 1679616

There are 676 domain names consisting of just two letters in a sequence that can be formed.

There are 1296 domain names of length two are there if digits, as well as letters, are per-mitted as characters.

There are 17576 domain names are there consisting of three letters in sequence.

There are 46656 of this length are there if either letters or digits are permitted.

As of April 2006, roughly 50 million web domain names were registered.

1. How many domain names consisting of just two letters in sequence can be formed?

There are 26 letters in the English alphabet.

Combining 2 domain names with letters alone will be;

[tex]\rm =n^2\\\\ = 26^2\\\\ =26 \times 26\\\\=676[/tex]

2. How many domain names of length two are there if digits, as well as letters, are per-mitted as characters.

If digits are allowed with letters:

There are 10 digits from 0-9.

Therefore 26 letters + 10 digits = 36

[tex]\rm = n^2 \\\\= 36^2 \\\\ = 36 \times 36 \\\\ = 1296[/tex]

3. How many domain names are there consisting of three letters in sequence?

There are 26 ways of choosing each character;

Therefore, the possible number of domains with three letters is;

[tex]= \rm n^3\\\\= 26^3\\\\= 26 \times 26 \times 26\\\\= 17576[/tex]

4. How many of this length are there if either letters or digits are permitted?

The digits are allowed, there are 26 + 10 = 36 characters to be used in total

Therefore, the possible number of domains with three characters is;

[tex]\rm = n^3 \\\\= 36^3 \\\\ = 36 \times 36 \times 36\\\\ = 46656[/tex]

Answer:

20 cm

Step-by-step explanation:

A2 + B2 = C2

 C is your hypotenuses = 29 cm

And one leg of a right triangle is 21 cm long

So we have A2 = (21cm)2 = 441 cm + B2 = (29cm)2 = 841cm

B2 = 841 - 441 = 400

 B = √400 = 20

So the third leg of a triangle that has a hypotenuses of 29 cm and one side of a right triangle that is 21 cm long is 20 cm

Answer:

x+4<12

Step-by-step explanation:

You did not put the inequalities, but that is how the statement would look like. "And" is a clue that we're adding. So, x + 4 would be the first part, and we know when the open part of this symbol '</>' is pointed at a number then that number is greater than the number before it. So, in this case, you'll want to have that symbol pointed at 12 because x + 4 is less than 12.

Answer:

[tex] 5(d - 4) [/tex]

Step-by-step explanation:

Entrance fee per head = d

Entrance fee for the 5 friends = 5*d = 5d

Booklet of ride ticket per head = 2.5d

Booklet of ride ticket for the 5 friends = 5(2.5d)

Meal ticket per head = d - 4

Meal ticket for the 5 friends = 5(d - 4)

Total amount paid altogether by the five friends = [tex] 5d + 5(2.5d) + 5(d - 4) [/tex]
