Samuel wants to create a password containing one, two, or three lowercase vowels followed by two digits. How many different passwords are possible? (Note: assume the letters "a", "e", "i", "o", and "u" are the ONLY vowels of the English alphabet.)
Using the fundamental counting principle, it is found that 15500 different passwords are possible.
----------------------------
The fundamental counting principle states that if there are p ways to do one things, and q ways to do other thing, and they are independent, there are p*q ways to do both things.
----------------------------
For each digit, there are 10 ways.For each vowel, there are 5 ways.The digits and the vowels are independent, thus, the fundamental counting principle is applied.----------------------------
With one vowel followed by two digits, there are [tex]5 \times 10^2 = 5 \times 100 = 500[/tex] passwords.With two vowels followed by two digits, there are [tex]5^2 \times 10^2 = 25 \times 100 = 2500[/tex] passwords.With three vowels followed by three digits, there are [tex]5^3 \times 10^2 = 125 \times 100 = 12500[/tex] passwords.In total, there are [tex]500 + 2500 + 12500 = 15500[/tex] passwords.A similar problem is given at https://brainly.com/question/23855405

Seven more than a number, x, is at most 20
Answer:
x+7 ≤ 20
Just take it step by step:
seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.
it then says it's equal to at most 20.
This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals
x+7≤ 20
≤ -this symbol means less than or equal to

While playing pool, you try to shoot the eight ball into the corner pocket.
Imagine that the coordinate plane is placed over the pool table. The eight ball is at ( 4, 3⁄4) and the pocket you are aiming for is at (10,4). You are going to make a bank shot at (6, 0).
a.) Write an equation for the path of the ball. b.) Do you make your shot? Why or why not?
Answer:
Step-by-step explanation:
to go from (4, 3/4 ) to (6, 0) you need
a line with slope m= (y2-y1)/(x2-x1) = [tex]\frac{3}{4}[/tex] -0 / 4-6 = [tex]\frac{3}{4} /\frac{-2}{1} =\frac{3}{4} *\frac{-1}{2} =\frac{-3}{8}[/tex]
use the quation of a line point-slope
(y-y1)=m(x-x1)
substitute m= -3/8 and (x1,y1) with (6,0)
[tex]y=\frac{-3}{8} (x-6)[/tex]
Now does point (10,4) where is the aim is verified by this equation?
substitute x=10, y=4 in the equation to check
4= -3(10-6)/8
4= -3*4/8
4=-3/2 this is never true so you do NOT make the shot
a.) The equation for the path of the ball is:[tex]\(y = -\frac{3}{8}x + \frac{9}{4}\).[/tex]
b.) The equation is not true because 4 is not equal to -3/2. Therefore, the ball does not make it into the pocket. The bank shot is not successful.The reason the shot fails is that the path of the ball (as represented by the linear equation) does not intersect the pocket point (10, 4), so the ball does not reach the desired target.
a.) To find the equation for the path of the ball, we can use the concept of a linear equation, which represents a straight line on the coordinate plane. The general form of a linear equation is:
[tex]\(y = mx + b\)[/tex]
where:
- y is the y-coordinate of a point on the line.
- x is the x-coordinate of the same point.
- m is the slope of the line (change in y divided by change in x).
- b is the y-intercept, which is the point where the line intersects the y-axis (x = 0).
a.) Equation for the path of the ball:
We can find the slope m of the line passing through (4, 3/4) and (6, 0) as follows:
[tex]\(m = \frac{{y_2 - y_1}}{{x_2 - x_1}} \\= \frac{{0 - \frac{3}{4}}}{{6 - 4}} \\= \frac{{-\frac{3}{4}}}{{2}} \\= -\frac{3}{8}\)[/tex]
Now, let's find the y-intercept b by substituting the values of (x, y) from one of the given points (let's use (4, 3/4)) and the calculated slope m :
[tex]\(y = mx + b\)\\\(\frac{3}{4} = -\frac{3}{8} \times 4 + b\)\\\(\frac{3}{4} = -\frac{3}{2} + b\)[/tex]
Now, solve for
[tex]\(b\): \(b = \frac{3}{4} + \frac{3}{2}\\ = \frac{3}{4} + \frac{6}{4} \\= \frac{9}{4}\).[/tex]
b.) To determine if the ball makes it into the pocket at (10, 4), we need to check if the y-coordinate (4) of the pocket point lies on the path of the ball. Substitute [tex]\(x = 10\) and \(y = 4\)[/tex] into the equation for the path of the ball:
[tex]\(4 = -\frac{3}{8} \times 10 + \frac{9}{4}\)\\\(4 = -\frac{30}{8} + \frac{9}{4}\)[/tex]
Now, let's find a common denominator and simplify:
[tex]\(4 = -\frac{30}{8} + \frac{18}{8}\)\\\(4 = -\frac{12}{8}\).[/tex]

Determine whether the ordered pair (10, 4) is a solution to the equation 3x – 5y = 10
Yes, (10,4) is a solution.
No, (10,4) is not a solution.
Answer:
Yes, (10,4) is a solution.
Step-by-step explanation:
3x - 5y = 10
Substitute x and y to see if you get 10;
x = 10
y = 4
3(10) - 5(4) = 10
30 - 20 = 10

Find x. Round to the nearest tenth if needed.
Answer:
x = 16
Step-by-step explanation:
Use that the addition of all internal angles of a triangle must add up to 180, and the fact that the two given triangles are similar:
51 + 65 + 4 x = 180
combine and solve for "x"
116 + 4 x = 180
4 x = 180 - 116
4 x = 64
x = 64 / 4
x = 16
Answer:
x = 16
Step-by-step explanation:
A triangle is 180 degrees. Since two of the angles are congruent to each other, the third angle must be congruent as well. This means that the third measure for both triangles is 4x. Knowing all of this, we can solve for x:
65 + 51 + 4x = 180
116 + 4x = 180
4x = 64
x = 16

right?
Answer:
if jack uses 10 cups of sugar he will need to use 6 tsp of vanilla extract
Step-by-step explanation:
10 devided by 2 1/2= 4
and 1/2 multiplied by 4 is 6
Answer:
2 tsp
Step-by-step explanation:
This is a ratio/ proportionality problem. The recipe calls for 2 1/2 cups of sugar, Jack uses 10 cups. Then 10/(2[tex]\frac{1}{2}[/tex]) = 4, meaning he used 4 times the amount of sugar than in the original. Using that, just multiply [tex]\frac{1}{2}[/tex] by 4 to get 4 times the vanilla of the og recipe, which equals 2 tsp.

CLOTHING A online retailer is running a special on jeans. All pairs of jeans are $39. The function f(x) = 39x models the total cost of buying x pairs of jeans. The retailer also charges $6 flat rate shipping fee. a. Write a function g(x) that represents the cost of purchasing jeans and having them shipped. b. Find the cost of purchasing 3 pairs of jeans before and after shipping
Answer:
a. g(x) = 39x + 6
b. The price before shipping is $117 and the price after shipping is $123
Step-by-step explanation:
To represent the cost of purchasing jeans and shipping them, add 6 to the function, since it is a flat rate.
So, the function will be g(x) = 39x + 6.
Then, use this function to find the cost of 3 pairs of jeans after shipping:
g(x) = 39x + 6
g(3) = 39(3) + 6
g(3) = 117 + 6
= $123
Then, use the original function, f(x) = 39x, to find the price before shipping:
f(x) = 39x
f(3) = 39(3)
= $117
So, the price before shipping is $117 and the price after shipping is $123
