A total of 175,760,000 different license plates are possible.

A permutation is a count of the different arrangements which can be made from a given set of things. In permutation the details matter, as the order or sequence is important. Permutation and combination are the methods employed in counting how many outcomes are possible in various situations. Permutations are understood as arrangements and combinations are understood as selections. As per the fundamental principle of counting, there are the sum rules and the product rules to employ counting easily.

According to this, if one event can occur in a ways and a second event can occur in b ways, the second event occurring after the first event did, then the two events can occur in a × b ways.

There are 26 letters in an English language.The license plate has 3 digits.  There are 10 digits from 0 to 10. The license plate has 4 digits.

The number of different license plate numbers that can be formed:

26 x 26 x 26 x 10 x 10 x 10 x 10 = 175,760,000

Thus, a total of 175,760,000 different license plates are possible.

The possible values of a are 1,2, and 4 from quadratic equation

Given a quadratic 4x^2 + bx + c, Jimmy successfully factors it as (ax + b)(cx + d), where a, b, c and d are integers. We are to determine the possible values of a

To find the value of a, we first need to multiply (ax + b)(cx + d). This gives

(ax + b)(cx + d) &= acx^2 + (ad + bc)x + bd \\&= 4x^2 + bx +c

Comparing the coefficients of x^2, we get ac = 4

Since a and c are integers, the only possible values of a and c are a = 1, c = 4or a = 2, c = 2 or a = 4, c = 1.

Comparing the constant terms, we get bd = c and so b and d are factors of c.

Therefore, the possible values of a are 1,2 and 4

The complete question is given below:

Find the slope of  linear equation 3x+4y=5?

Answer:

1.

\(C.\\sin(N)=\frac{\sqrt{3} }{2}\)

2.

\(x=82.1\)

3.

x = 18°

Step-by-step explanation:

1. The sine ratio is sin(θ) = opposite/hypotenuse, where θ is the reference angle.  When N is the reference angle, we see that side OP with a measure of 5√3 units is the opposite side and side NP with a measure of 10 units is the hypotenuse.

Thus, we can find plug everything into the sine ratio and simplify:

\(sin(N)=\frac{5\sqrt{3} }{10} \\\\sin(N)=\frac{\sqrt{3} }{2}\)

2. We can use the tangent ratio to solve for x, which is tan (θ) = opposite/adjacent.  If we allow the 75° to be our reference angle, we see that the side measuring x units is the opposite side and the side measuring 22 units is the adjacent side.  Thus, we can plug everything into the ratio and solve for x or the measure of the opposite side:

\(tan(75)=\frac{x}{22}\\ \\22*tan(75)=x\\\\82.10511777=x\\\\82.1=x\)

3. Since we're now solving for an angle, we must using inverse trigonometry.  We can use the inverse of the tangent ratio, whose equation is tan^-1 (opposite/adjacent) = θ.  We see that when the x° is the reference angle, the side measuring 11 units is the opposite and the side measuring 33 units is the adjacent side.  Now we can do the inverse trig to find the measure of x:

\(tan^-^1(\frac{11}{33})=x\\ 18.43494882=x\\18=x\)

The expression is which gives an estimate of how tall Justin will be as an adult is

\(\dfrac{x+y+5}{2}\)

where, x and y are his parents’ current heights in inches.

Mom’s height = 54 inches Dad’s height = 71 inches.

His calculation:

\(\dfrac{71+54+5}{2}=71+27+5=103\ inches\)

To find:

Justin's mistake.

Solution:

Let x be Dad’s height  and y be Mom’s height. So, correct estimation for his height is

\(\dfrac{71+54+5}{2}=\dfrac{130}{2}\)

\(\dfrac{71+54+5}{2}=65\)

He should have added the values in the numerator before dividing by 2.

The number of prime factors of 3×5×7+7 is 3.

To find the number of prime factors, we need to calculate the given expression:

3×5×7+7 = 105+7 = 112.

The number 112 can be factored as 2^4 × 7.

In the first step, we factor out the common prime factor of 7 from both terms in the expression. This gives us 7(3×5+1). Next, we simplify the expression within the parentheses to get 7(15+1). This further simplifies to 7×16 = 112.

So, the prime factorization of 112 is 2^4 × 7. The prime factors are 2 and 7. Therefore, the number of prime factors of 3×5×7+7 is 3.

In summary, the expression 3×5×7+7 simplifies to 112, which has three prime factors: 2, 2, and 7. The factor of 2 appears four times in the prime factorization, but we count each unique prime factor only once. Thus, the number of prime factors is 3.

Answer:

Step-by-step explanation:

Imagine coordinate system

I quarter is where x>0 and y>0  {right top} and it is (0°,90°)

II quarter is where x<0 and y>0  {left top} and it is (90°,180°)

III quarter is where x<0 and y<0  {left bottom} and it is (180°,270°)

IV quarter is where x>0 and y<0  {right bottom} and it is (270°,360°)

Now, we have an angle wich vertex is point (0,0) and one of its sides is X-axis and the second lay at one of the quarters.

For the trig functons of an angle created by this second side always are true:

In first quarter all functions are >0

in second one only sine

in third one: tangent and cotangent

and in fourth one: cosine

{You can check this by selecting any point on the second side of angle and put it's coordinates to formulas of these functions:

\(\sin \phi=\dfrac y{\sqrt{x^2+y^2}}\,,\quad \cos \phi=\dfrac x{\sqrt{x^2+y^2}}\,,\quad \tan\phi=\dfrac yx\,,\quad \cot\phi=\dfrac xy\)  }

So:

sinφ<0  ⇒ III or IV quarter

tanφ<0  ⇒ I or IV quarter

IV quarter  ⇒  φ ∈ (270°, 360°)

f(4) is 1/2

f(x)= 4 when x is 8

The complete statements would be as:

function f(4) is 1/2 and function f(x) = 4 when domain x is 8.

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

We have been given that the mapping diagram shows a functional relationship.

To determine the value of f(4)

As per the given functional relationship,

If the value of the domain is 4 then the value of the respective range would be 1/2.

Therefore, the function f(4) would be 1/2.

To determine the value of x,  when f(x) = 4

As per the given functional relationship,

If the value of the range is 4 then the value of the respective domain would be 8.

Therefore, x would be 8 if function f(x) = 4 .

Hence, the complete statements would be as:

f(4) is 1/2 and f(x) = 4 when x is 8.

For a certain species of virulent bacteria with the rate of growth of the bacterial population as proportional to the number the bacteria present after 3 hours is 256000.

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decline or exponential growth, and so forth.

When there is exponential growth, the quantity grows initially extremely slowly and subsequently quickly. Over time, the rate of change quickens. As time goes on, the rate of increase accelerates. It is intended for the quick growth to be a "exponential increase".

The species of bacteria follow an exponential growth pattern.

The exponential growth is given as:

\(A(t) = A_0e^{kt}\)

Where, A₀ is the initial population = 4000

k = constant

t = time = 30 minutes = 1/2 hour.

The bacteria doubles in 30 minutes, thus A(t) = 2(4000) = 8000.

Substituting the values in the equation:

\(8000 = 4000e^{k(\frac{1}{2} )}\\\\2 = e^{k(\frac{1}{2} )}\)

Takin ln on both sides of the equation:

ln(2) = 1/2 k

2(ln(2)) = k

k = 1.38

The number of bacteria present after 3 hours:

\(A(t) = 4000e^{(1.38)(3)}\\\\\)

A(t) = 256000

Hence, for a certain species of virulent bacteria with the rate of growth of the bacterial population as proportional to the number the bacteria present after 3 hours is 256000.
