Step-by-step explanation:
A license plate consists of three letters followed by
three digits. How many license plates are possible if
no letter may be repeated?
Answer: 15,600,000
Step-by-step explanation:
26 x 25 x 24 =15,600 combinations of letter with no repeats
10 x 10 x 10 = 1000 with repeating numbers
15,600 x 1000 = 15,600,000
The total number of possible license plates is 26*25*24*10*9*8.
The number of possible license plates with no repeated letters can be calculated by multiplying the number of choices for each position. Since no letter can be repeated, the choices for the first position would be 26 letters, then 25, and then 24 for the three positions. For the digits, there are 10 choices for each position.
So, the total number of possible license plates would be 26*25*24*10*9*8.

What is the measure of <B 98 108 118 128
Answer:
Step-by-step explanation:
By observation, you can see that the irregular polygon can be split into 4 triangles (see attached image). We know that the sum of the internal angles of 1 triangle is always 180 degrees. Hence the sum of all the internal angles of the polygon is,
180 degrees x 4 triangles = 720 degrees.
Therefore Angle B,
= sum of internal angles - sum of all other known angles
= 720 - (133 +102+117+90+170)
= 108 degrees.
The measure of angle B is 108 degrees.
What is angle sum property?
Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
We can divide the given polygon in split into 4 triangles.
Using, angle sum property,
The sum of the internal angles of triangle is always 180 degrees.
Hence the sum of all the internal angles of the polygon is,
=180 x 4 triangles
= 720 degrees.
Now, angle B
= 720 - (133 +102+117+90+170)
=720 -612
= 108 degrees.
Hence, angle B is 108 degrees.

If two angels are congruent, then the sides opposite those angles are congruent. True or false.
Answer:
The statement is True
Step-by-step explanation:
The Isosceles Triangle Theorem states that;
If two sides of a triangle are congruent, then the angles opposite those sides are also congruent. The converse of this statement is;
if two angles are congruent, then sides opposite those angles are congruent.
Answer:
True.
Step-by-step explanation:
To start with , remember that congruent angles have the same degree of measurement. For example, in an isosceles triangle, the base angles are congruent angles because they both measure 45°
The base angles theorem states that the sides next to congruent angles are equal.The statement is therefore True.If sides of the triangle are congruent, the opposite angles in the triangle are congruent .
Billy is helping to make pizzas for a school function. He's made 25 pizzas so far. His principal asked him to make at least 30 pizzas but no more than 75. Solve the compound inequality and interpret the solution.
30 ≤ x + 25 ≤ 75
Answer: Number of pizzas would be less than 5 but not more than 50.
Step-by-step explanation:
Since we have given that
Number of pizzas so far = 25
His principal asked him to make at least 30 pizzas but no more than 75.
According to question, we have
30 ≤ x + 25 ≤ 75
First we subtract 25 from both the sides:
[tex]30-25\leq x \leq 75-25\\\\=5\leq x\leq 50[/tex]
Hence, number of pizzas would be less than 5 but not more than 50.
The solution to the compound inequality is 5 x 50.
The compound inequality given is 30 x 25 75, where x represents the number of additional pizzas Billy needs to make to satisfy the principal's request. To solve for x, we need to isolate x in the inequality.
First, we subtract 25 from all parts of the compound inequality to shift the 25 pizzas already made to the other side of the inequality. This gives us:
30 - 25 x + 25 - 25 75 - 25
Simplifying the inequality, we get:
5 x 50
This means that Billy needs to make at least 5 more pizzas to reach the minimum requirement of 30 pizzas (since 25 + 5 = 30) and no more than 50 additional pizzas to not exceed the maximum allowed number of 75 pizzas (since 25 + 50 = 75).
Therefore, the number of additional pizzas Billy should make is any integer value between 5 and 50, inclusive. This ensures that the total number of pizzas made will be within the principal's specified range of 30 to 75 pizzas."

A grid shows the positions of a subway stop and your house. The subway stop is located at (-5,2) and your house is located at (-9,9). what is the distance, to the nearest unit, between your house and the subway stop?
Answer:
8
Step-by-step explanation:
Calculate the distance (d) using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 5, 2) and (x₂, y₂ ) = (- 9, 9)
d = [tex]\sqrt{(-9+5)^2+(9-2)^2}[/tex]
= [tex]\sqrt{(-4)^2+7^2}[/tex]
= [tex]\sqrt{16+49}[/tex] = [tex]\sqrt{65}[/tex] ≈ 8 ( nearest unit )
Answer: The required distance between my house and the subway stop is 8 units.
Step-by-step explanation: Given that a grid shows the positions of a subway stop and my house. The subway stop is located at (-5,2) and my house is located at (-9,9).
We are to find the distance, to the nearest unit, between my house and the subway stop.
We will be using the following formula :
Distance formula : The distance between the points (a, b) and (c, d) is given by
[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]
Therefore, the distance between the points (-5, 2) and (-9, 9) is given by
[tex]D\\\\=\sqrt{(-9-(-5))^2+(9-2)^2}\\\\=\sqrt{(-9+5)^2+7^2}\\\\=\sqrt{4^2+49}\\\\=\sqrt{16+49}\\\\=\sqrt{65}\\\\=8.06.[/tex]
Rounding to the nearest units, we get
D = 8 units.
Thus, the required distance between my house and the subway stop is 8 units.
Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
Answer:
a = 3 , b = -2 , c = 0
Step-by-step explanation:
The given equation is:
1 = -2x + 3x^2 + 1
To find the correct substitution values of a, b and c. We need to convert t into the standard form first.
Standard form of a Quadratic equation is written as:
ax^2 + bx + c = 0 (where a is not equal to zero)
Converting the given equation into its standard form:
1 = -2x + 3x^2 + 1
-2x + 3x^2 + 1 - 1 = 0
3x^2 - 2x + 0 = 0
OR 3x^2 - 2x = 0
According to the equation
a = 3 , b = -2 , c = 0

An answer is
[tex]\displaystyle f\left(x\right)=\frac{\left(x+1\right)^3}{\left(x+2\right)^2\left(x-1\right)}[/tex]
Explanation:
Template:
[tex]\displaystyle f(x) = a \cdot \frac{(\cdots) \cdots (\cdots)}{( \cdots )\cdots( \cdots )}[/tex]
There is a nonzero horizontal asymptote which is the line y = 1. This means two things: (1) the numerator and degree of the rational function have the same degree, and (2) the ratio of the leading coefficients for the numerator and denominator is 1.
The only x-intercept is at x = -1, and around that x-intercept it looks like a cubic graph, a transformed graph of [tex]y = x^3[/tex]; that is, the zero looks like it has a multiplicty of 3. So we should probably put [tex](x+1)^3[/tex] in the numerator.
We want the constant to be a = 1 because the ratio of the leading coefficients for the numerator and denominator is 1. If a was different than 1, then the horizontal asymptote would not be y = 1.
So right now, the function should look something like
[tex]\displaystyle f(x) = \frac{(x+1)^3}{( \cdots )\cdots( \cdots )}.[/tex]
Observe that there are vertical asymptotes at x = -2 and x = 1. So we need the factors [tex](x+2)(x-1)[/tex] in the denominator. But clearly those two alone is just a degree-2 polynomial.
We want the numerator and denominator to have the same degree. Our numerator already has degree 3; we would therefore want to put an exponent of 2 on one of those factors so that the degree of the denominator is also 3.
A look at how the function behaves near the vertical asympotes gives us a clue.
Observe for x = -2,
as x approaches x = -2 from the left, the function rises up in the positive y-direction, andas x approaches x = -2 from the right, the function rises up.Observe for x = 1,
as x approaches x = 1 from the left, the function goes down into the negative y-direction, andas x approaches x = 1 from the right, the function rises up into the positive y-direction.We should probably put the exponent of 2 on the [tex](x+2)[/tex] factor. This should help preserve the function's sign to the left and right of x = -2 since squaring any real number always results in a positive result.
So now the function looks something like
[tex]\displaystyle f(x) = \frac{(x+1)^3}{(x+2 )^2(x-1)}.[/tex]
If you look at the graph, we see that [tex]f(-3) = 2[/tex]. Sure enough
[tex]\displaystyle f(-3) = \frac{(-3+1)^3}{(-3+2 )^2(-3-1)} = \frac{-8}{(1)(-4)} = 2.[/tex]
And checking the y-intercept, f(0),
[tex]\displaystyle f(0) = \frac{(0+1)^3}{(0+2 )^2(0-1)} = \frac{1}{4(-1)} = -1/4 = -0.25.[/tex]
and checking one more point, f(2),
[tex]\displaystyle f(2) = \frac{(2+1)^3}{(2+2 )^2(2-1)} = \frac{27}{(16)(1)} \approx 1.7[/tex]
So this function does seem to match up with the graph. You could try more test points to verify.
======
If you're extra paranoid, you can test the general sign of the graph. That is, evaluate f at one point inside each of the key intervals; it should match up with where the graph is. The intervals are divided up by the factors:
x < -2. Pick a point in here and see if the value is positive, because the graph shows f is positive for all x in this interval. We've already tested this: f(-3) = 2 is positive.-2 < x < -1. Pick a point in here and see if the value is positive, because the graph shows f is positive for all x in this interval.-1 < x < 1. Pick a point here and see if the value is negative, because the graph shows f is negative for all x in this interval. Already tested since f(0) = -0.25 is negative.x > 1. See if f is positive in this interval. Already tested since f(2) = 27/16 is positive.So we need to see if -2 < x < -1 matches up with the graph. We can pick -1.5 as the test point, then
[tex]\displaystyle f(-1.5) = \frac{\left(-1.5+1\right)^3}{\left(-1.5+2\right)^2\left(-1.5-1\right)} = \frac{(-0.5)^3}{(0.5)^2(-2.5)} \\= (-0.5)^3 \cdot \frac{1}{(0.5)^2} \cdot \frac{1}{-2.5}[/tex]
We don't care about the exact value, just the sign of the result.
Since [tex](-0.5)^3[/tex] is negative, [tex](0.5)^2[/tex] is positive, and [tex](-2.5)[/tex] is negative, we really have a negative times a positive times a negative. Doing the first two multiplications first, (-) * (+) = (-) so we are left with a negative times a negative, which is positive. Therefore, f(-1.5) is positive.

Use substitution to write an equivalent quadratic equation.
(3x + 2)2 + 7 (3x + 2) – 8 = 0
-
u2 + 74 - 8 = 0, where u = (3x + 2)2
u2 + 7u - 8 = 0, where u = 3x + 2
u2 + 70 - 8 = 0, where u = 7(3x + 2)
lu² +4-8=0

Answer:
Option B
Answer:
second option: [tex]u^{2}+7u-8=0[/tex]
Step-by-step explanation:
We have the equation given:
[tex](3x+2)^{2}+7(3x+2)-8=0[/tex]
We can replace the variable in the quardatic equation.
So,
[tex]Putting\\u=3x+2[/tex]
Putting u in place of 3x+2 will give us:
[tex](u)^{2}+7(u)-8=0[/tex]
So the answer is:
[tex]u^{2}+7u-8=0[/tex]
So, the second option is correct ..
