A. There are 33 special characters.
B. The probability of guessing the password under the given circumstances is 1 out of 858 combinations.
Step-by-step explanation:
Step 1; First we need to determine all the possible values that can come in each space of the password.
From 0 to 9, there are a total of 10 values.
For uppercase letters, there are a total of 26 values from A, B, C, D ...Z
For lower case letters, there are also a total of 26 values from a, b, c, d ...z.
So out of these three characters, we have a total of 10 × 26 × 26 = 6,760 different combinations.
If there are 223,080 password combinations we need to divide this by 6,760 to calculate the possible values of the special characters.
6,760 × Number of possible special characters = 223,080,
Number of special characters = [tex]\frac{223,080}{6,760}[/tex] = 33. So there are 33 special characters.
Step 2; If the number and uppercase values are known then the various lowercase letters and special characters are the unknown values.
The number of possible combinations = number of lowercase letters × number of special characters = 26 × 33 = 858.
So the probability of guessing the password is 1 out of 858 combinations.
(a) There are 216,320 special characters in the password combinations.
(b) The probability of guessing the account password with knowledge of the number and uppercase letter, but not the rest, is [tex]\(\frac{320}{11}\)[/tex].
Let's solve each part of the problem:
(a) Number of Special Characters:
Given that there are 223,080 password combinations and the special character comes last, it means there are 10 possible numbers (0-9), 26 possible uppercase letters, and 26 possible lowercase letters, leaving the remaining positions for special characters. Therefore, the number of special characters is:
[tex]\[ \text{Number of special characters} = 223,080 - (10 \times 26 \times 26) = 223,080 - 6760 = {216,320} \][/tex]word:
If you know the number and uppercase letter but forget the rest, you only need to guess the lowercase letter and special character. The total number of possible lowercase letters is 26, and the total number of possible special characters is 216,320 (calculated in part a).
Therefore, the probability of guessing the account password is:
[tex]\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} = \frac{26 \times 216,320}{223,080} \]\[ \text{Probability} = \frac{6,387,520}{223,080}[/tex]

The fifth power of the number 27 is equal to 3¹⁵.
To find the fifth power of a number that is equal to 3¹⁵, we need to determine what number raised to the power of 5 gives us 3¹⁵.
Let's call the number we are looking for "x." So, we need to solve the equation:
x⁵ = 3¹⁵
To find x, we can take the fifth root of both sides of the equation:
x = (3¹⁵[tex])^{(1/5)[/tex]
x = 3³
x = 27
This means that if we raise 27 to the power of 5 (27⁵), we will get 3¹⁵ (3 raised to the power of 15).
In conclusion, the number we are looking for is 27, as 27^5 is equal to 3¹⁵.

I need help on this please can someone help me with this
Answer:
C. 11
Step-by-step explanation:
First, find the value of "x" by solving the first equation. You need to move every other number to the other side of "x". When you move a number, you have to do the opposite operation to both sides.
5x + 6 = 10 The opposite of +6 is -6.
5x + 6 - 6 = 10 - 6 Subtract 6 from both sides
5x = 10 - 6 The "6" on the left cancelled out. Simplify the right side
5x = 4 The opposite of multiply by 5 is divide by 5
5x/5 = 4/5 Divide both sides by 5
x = 4/5 Value of "x"
Substitute the value of "x", which is 4/5, in the "x" for the second equation.
10x + 3
= 10(4/5) + 3 Multiply 10 and 4/5
= [tex]\frac{10*4}{5}[/tex] + 3 Combine into the numerator
= [tex]\frac{40}{5}[/tex] + 3 Divide the top by the bottom
= 8 + 3 Add
= 11 Value of second equation
Therefore the value of 10x + 3 is 11.
A pen in the shape of an isosceles right triangle with legs of length x ft and hypotenuse of length h ft is to be built. If fencing costs $ 4 divided by ft for the legs and $ 16 divided by ft for the hypotenuse, write the total cost C of construction as a function of h.
Answer:
[tex]\frac{8h}{\sqrt{2}} + 16h[/tex]
Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have
[tex]x^2 + x^2 = h^2[/tex]
[tex]2x^2 = h^2[/tex]
[tex]x = \frac{h}{\sqrt{2}}[/tex]
The cost for the legs is
[tex]C_l = 4*2x = \frac{8h}{\sqrt{2}}[/tex]
The cost for the hypotenuse is
[tex]C_h = 16h[/tex]
So the total cost in term of h is
[tex]C = C_l + C_h = \frac{8h}{\sqrt{2}} + 16h[/tex]
The total cost C of construction as a function of h is C = 16 / h + 8√2 / h
The pen is in the shape of an isosceles right angle. This means one of the
angle is 90 degrees and 2 sides of the triangle are equal and the base angles
are equal too.
Using pythagora's theorem
Therefore,
x² + x² = h²
2x² = h²
x² = h² / 2
x = √h²/ √2 = h/√2
cost of the legs = 4 / h/√2 + 4 / h /√2 = 8√2 / h
cost of the hypotenuse = 16 / h
Total cost = 16 / h + 8√2 / h
C = 16 / h + 8√2 / h

Inverse property of multiplication: For all real numbers except , a • = 1.
Answer:
[tex]\text{Inverse property of multiplication: For all real numbers except }0,\text{ }a\cdot 1/a=1[/tex]
Explanation:
These are the examples given to illustrate the inverse property of multiplication:
[tex]1/5\cdot 5=1\\\\ \sqrt{2}\cdot (1/\sqrt{2})=1[/tex]
And you must complete the statement to describe the property.
Inverse property of multiplication: For all real numbers except __, a • __ = 1.In the first example, 1/5 and 5 are reciprocal numbers of each other, also known as multiplicative inverses. And the example is showing that the product of 1/5 and its reciprocal is 1.
In the second example, [tex]\sqrt{2}\text{ and }(1/\sqrt{2})[/tex] are reciprocal of each other. Again, the example is showing that the product of those a number at its reciprocal is 1.
That is a general property, that can be written as:
[tex]a\cdot 1/a=1[/tex]
That property is satisfied by any number except 0, because the reciprocal of [tex]0[/tex] , i.e. [tex]1/0[/tex] is not defined.
Then, the statemen is:
[tex]\text{For all real numbers except }0,\text{ }a\cdot 1/a=1[/tex]
The statement that best describes the inverse property of multiplication is: Inverse property of multiplication: For all real numbers except 0, a * a⁻¹ = 1.
This means that if you multiply a number by its reciprocal, you will always get 1.
The examples you provided illustrate this property nicely:
5 * 1/5 = 1
√2 * 1/√2 = 1
Note that the inverse property of multiplication does not hold for the number 0, because the reciprocal of 0 is undefined.
Here is another example of the inverse property of multiplication:
3 * 1/3 = 1
You can check any other real number and its reciprocal, and you will always find that the product is 1.
The inverse property of multiplication is a useful property in mathematics, and it is used in many different areas, such as algebra, calculus, and physics.

QUESTION 4 of 10: Your restaurant purchases 1,625 bottles of Chablis per year. The annual increase of purchases has been 6%. If this
increase continues for 5 years, what will be your average increase in bottles purchased per year over that time?
a) 110 bottles
b) 190 bottles
c) 260 bottles
d) 400 bottles
Answer:
A - 110
Step-by-step explanation:
So if it is 6% increase you would times the number by 1.06. So you would do this like 5 times:
1,625 x 1.06 = 1722.5
1722.5 x 1.06 = 1825.85
1825.85 x 1.06 = 1935,401
1935.401 x 1.06 = 2051,52506
2051.52506 x 1.06 = 2174,6165636
Now you have the total number of bottles after 5 years, you would find the increase which is 2174.6165636 - 1,625 ≈ 550. 550 / 5 = 110

The average increase in bottles purchased per year over that time is c) 110 bottles.
What is percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.
Now it is given that,
Number of bottles purchased per year, a = 1,625
Percentage increase per year, r = 6% = 0.06
Total time period, n = 5 years
Since, the equation of a exponential growth function is given as,
y = a(1 +r)ⁿ
⇒ y = 1625(1 +0.06)⁵
⇒ y = 1625(1.06)⁵
⇒ y = 1625*1.338
⇒ y = 2,175
Therefore, average increase in bottles purchased per year over that time = (2175 - 1625) / 5
= 550 / 5
= 110 bottles
Thus, the average increase in bottles purchased per year over that time is c) 110 bottles.

f(x) = –2x2 + 16x – 35
f(x) = one-halfx2 – 4x + 5
f(x) = 2x2 – 16x + 35
Answer:
f(x) = 1/2x^2 – 4x + 5 (the third option)
Step-by-step explanation:
I looked it up on a graphing calculator.
The quadratic function that has a minimum located at (4, -3) is:
[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]
Which function has a minimum located at (4, -3)?All the options are quadratic functions, so we need to find the one with a leading coefficient positive, which also has a vertex at (4, -3).
The 3 ones with positive leading coefficients are:
[tex]f(x) = (1/2)*x^2 + 4x -11[/tex]
[tex]f(x) = (1/2)*x^2 - 4x + 5[/tex]
[tex]f(x) = 2x^2 - 16x + 35[/tex]
The vertex of the first one is at:
[tex]x = -4/(2*1/2) = -4[/tex]
The x-value of the vertex must be x = 4, so we can discard this.
For the second quadratic function the x-value of the vertex is:
[tex]x = -(-4)/(2*1/2) = 4[/tex]
Then the y-value of the vertex is:
[tex]f(4) = (1/2)*4^2 - 4*4 + 5 = -3[/tex]
Then the vertex is at (4, -3), so this is the correct option.

"15 times a number w"
Answer:
15×w
Step-by-step explanation:
15 times w is a number bigger 15 times or added up again and again 15 times:
w+w+w+w+w+w+w+w+w+w+w+w+w+w+w or 15×w
The expression to represent "15 times a number w" is written as 15w. Substituting ½ for w would lead to the multiplication 15 × ½, resulting in 7.5.
Explanation:To represent the phrase "15 times a number w," you would write the algebraic expression 15w. This is accomplished by using the coefficient 15 to indicate that the number w is being multiplied by 15. So, if you were to substitute the value ½ for w into this expression, you would perform the multiplication 15 × ½ to get the result, which simplifies to 7.5.

Find the coordinates of the epicenter.
Answer:
(-2, -3)
Step-by-step explanation:
A careful graph shows the point (-2, -3) is at the intersection of the circles whose radii are the given distances from the receiving stations.
_____
The simultaneous equations for the circles can be solved algebraically.
The epicenter is 10 units from X, so lies on the circle ...
(x -4)^2 +(y -5)^2 = 10^2
x^2 -8x +16 +y^2 -10y +25 = 100
x^2 +y^2 -8x -10y = 59
__
The epicenter is 5 units from Y, so lies on the circle ...
(x +6)^2 +(y +6)^2 = 5^2
x^2 +12x +36 +y^2 +12y +36 = 25
x^2 +y^2 +12x +12y = -47

The epicenter is 13 units from Z, so lies on the circle ...
(x +14)^2 +(y -2)^2 = 13^2
x^2 +28x +196 +y^2 -4y +4 = 169
x^2 +y^2 +28x -4y = -31
__
Subtracting the second equation from each of the other two, we get ...
(x^2 +y^2 -8x -10y) -(x^2 +y^2 +12x +12y) = (59) -(-47)
-20x -22y = 106 . . . . eq1 -eq2

These simultaneous linear equations can be solved a variety of ways. We might use substitution:
x = y+1 . . . . . from eq3 -eq2 divided by 16
10(y +1) +11y = -53 . . . . . from eq1 -eq2 divided by -2
21y = -63 . . . . . . . . . . . . simplify, subtract 10
y = -3
x = y+1 = -2
The epicenter is located at (x, y) = (-2, -3).

6v+13b=377
4v+9b=259
Answer:
v = 13
b = 23
Step-by-step explanation:
To solve this system of equations, we can negate one equation and add it to other to cancel out one variable.
Looking at v and b, the coefficients are 6, 4 and 13, 9, respectively.
It would be easier to use the LCM of 6 and 4
[tex]E_1 : 6v + 13b = 377\\E_2: 4v + 9b = 259\\\\4E_1 + (- 6)E_2:\\24v + 52b = 1508\\-24v - 54b=-1554\\\\0v -2b = -46\\-2b = -46\\b = 23\\\\4v + 9(23) = 259\\4v + 207 = 259\\4v = 52\\v = 13\\\\6(13) + 13(23)\\78 + 299\\377[/tex]
