Answer:

Quadratic polynomial (Biggest power is 2). It's also a trinomial (3 unlike terms)

The perimeter of the original rectangle is 17.6mm. The side length of the enlarged rectangle is 23.22mm and the perimeter of the enlarged rectangle is 95.04mm

The formula for calculating the perimeter of a rectangle is expressed as;

P = 2(l +w)

If the smaller rectangle has a length of 4.3 millimeters and width of 4.5 millimeters while a larger rectangle has a length of x millimeters and width of 24.3 millimeters, then;

4.3/x = 4.5/24.3

Cross multiply

4.5x = 104.49

x = 23.22mm

Perimeter of original rectangle = 2(4.3 + 4.5)

Perimeter of original rectangle = 17.6mm

Perimeter of enlarged rectangle = 2(23.22 + 24.3)

Perimeter of enlarged rectangle = 95.04mm

The perimeter of the original rectangle is 17.6mm. The side length of the enlarged rectangle is 23.22mm and the perimeter of the enlarged rectangle is 95.04mm

Step-by-step explanation:

Answer:

given : 0.61 per year

formula poisson probability : p(x=k)=xke-x/k!

(a) The parameter λ is the product of the rate per year and the number of years. The number of years is 1 year in this case.

λ=0.61×1=0.61

Evaluate the formula of the Poisson probability at k=0,1:

P(X=0)= 0!

(0.61)

0

e

−0.61

​

≈0.5434

P(X=1)=

1!

(0.61)

e

​

≈0.3314

Add the corresponding probabilities:

P(X≤1)=P(X=0)+P(X=1)=0.5434+0.3114=0.8748

Use the complement rule:

P(X>1)=1−P(X≤1)=1−0.8748=0.1252

Resolviendo una ecuación lineal veremos que que Manuel tiene 36 años.

Vamos a definir la edad de Manuel como x.

Sabemos que la mitad mas el tercio mas la cuarta parte de x es igual que x más 3, entonces:

x/2 + x/3 + x/4 = x + 3

Ahora podemos resolver esta ecuación lineal para x:

x/2 + x/3 + x/4 - x = 3

x*( 1/2 + 1/3 + 1/4 - 1) = 3

x = 3/(1/2 + 1/3 + 1/4 - 1) = 36

The table of values is

x -1 0 1 2 3 4 5 6

f(x) -13 -7 -1 11 35 77 143 139

The function is given as:

f(x) = x³ +5x-7

And the values of x are

x = -1, 0, 1, 2, 3, 4 5 and 6.​

Substitute these values in the function

f(-1) = (-1)³ +5(-1) - 7 = -13

f(0) = (0)³ +5(0) - 7 = -7

f(1) = (1)³ +5(1) - 7 = -1

f(2) = (2)³ +5(2) - 7 = 11

f(3) = (3)³ +5(3) - 7 = 35

f(4) = (4)³ +5(4) - 7 = 77

f(5) = (5)³ +5(5) - 7 = 143

Answer: B. Reciprocal

Step-by-step explanation:

This is a fact.

The parent function represented by f(x) = -1/x is the reciprocal function.

Therefore, the correct answer is option B.

Reciprocal functions, also known as rational functions, are defined by an algebraic expression where the dependent variable is in the denominator. In this case, the dependent variable is x, and it appears in the denominator as 1/x.

The negative sign in front of the fraction simply indicates that the function is reflected over the x-axis.

The general form of a reciprocal function is f(x) = a/x, where "a" is a constant. In the given function f(x) = -1/x, a is equal to -1.

In the case of f(x) = -1/x, the graph of the function is a hyperbola that opens downwards in the first and third quadrants. It approaches the x-axis as x moves towards positive or negative infinity, and it moves away from the x-axis as x approaches 0.

Therefore, the correct answer is option B, the reciprocal function.

The $1 belongs in the box.

s + c = 47 equation 1

5s + 4c = 200 equation 2

Multiply equation 1 by 5

5s + 5c = 235

Subtract equation 2 from equation 3

c = 35

Subtract 35 from 47

c = 47 - 35 = 12

35 couples tickets and 12 individual tickets were sold. This is not possible since the couples tickets were sold in 2.

s + c = 47 equation 1

5s + 4c = 201 equation 2

Multiply equation 1 by 5

5s + 5c = 235

Subtract equation 2 from equation 3

c = 34

34 is divisible by 2 so the $1 belongs in the box.

Part B

Diagonals of a parallelogram bisect each other, so

All polar coordinates of point P where P = ordered are given are mathematically given as

Option B is correct.

Generally, the equation for all polar coordinates is mathematically given as

Finding the whole set of polar coordinates for An arbitrary point's polar coordinates may be written as (r, ), where (r, ) = (r, +2n) for some n and r.

In conclusion, we may solve the problem by setting r = 6 and = -/6.

If n is an integer and r is positive, then P(6,-/6) = (6, -/6) + 2n, and if n is an integer and r is negative, then P(-6,-/6) = (-6, -/6) + (2n+1).

The rate at 14% and 5% are $12, 883 and $2191 respectively.

Given that;

Invested amount = $ 15, 074 at 14% and 5%

Let rate at 14% = x

rate at 5% = y

We have rate at 9% exceeds that of 5% by $1694. 07

Hence,

0. 14x = 0. 05y + $1694. 07 ⇒ equation 1

x + y = $15, 074 ⇒ equation 2

Make 'x' the subject

x = [tex]15, 074 - y[/tex]

Substitute in equation 2

[tex]0. 14(15, 074 - y) = 0. 05y + $1694. 07[/tex]

Make 'y' the subject

y = [tex]\frac{416. 29}{0. 19}[/tex]

y = [tex]$2, 191[/tex]

Substitute the value in equation 2

x + y = $15, 074

x = $15, 074 - y

Answer:

(0, 22)

Step-by-step explanation:

So you have the equation:

[tex]y-1=-7(x-3)[/tex]

So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:

[tex]y-1 = -7(0-3)[/tex]

[tex]y-1 = -7(-3)[/tex]

[tex]y-1=21[/tex]

[tex]y=22[/tex]

So the y-intercept is at (0, 22)

Answer:

We can now take 2 as the third digit, 3 as the fourth digit, 4 as the fifth digit and finally 5 as the sixth digit. Therefore, the smallest 6-digit number having all different digits is 102345.

The smallest 6-digit multiple of 4 with all different numbers is 102,564. This number is obtained by incrementing from 100,000 until finding a divisible number with distinct digits.

A number that is the result of a given number plus another natural number is said to be a multiple of that number.

Since the smallest 6-digit number, is 100,000.

Check if this number is divisible by 4.

In this case, it is not.

Increment the number by 1 to get 100,001.

Repeat step 2. Not divisible by 4.

Increment the number by 1 to get 100,002.

Repeat step 2. Not divisible by 4.

Increment the number by 1 to get 100,003.

Repeat step 2. Not divisible by 4.

Continue this process until you find a number that is divisible by 4 and has all different digits.

After following these steps, we find that the smallest 6-digit multiple of 4 with all different numbers is 102,564.

Hence,

The required number is 102564.

The total amount of chocolates in the box is 8 + 16 + 14 = 38, 14 of which are solid.

Let's calculate the probability of getting a solid chocolate in the first selection:

Given that the first piece was solid, there are now 37 pieces of chocolate in the box, 13 of which are solid. Let's now calculate the probability of selecting another solid chocolate:
