3 different ways to do it.

Using the combination formula, it is found that there are 35 ways to do this.

The order in which the vegetables are included is not important, thus, the combination formula is used to solve this question.

Combination formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given as follows:

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

In this problem, 4 vegetables from a set of 7, thus:

[tex]C_{7,4} = \frac{7!}{4!(7-4)!} = 35[/tex]

8. y = -4

Step-by-step explanation:

2 ( -2y - 6 ) + 10 = -4y + 22 + 6y

-4y - 12 + 10 = -4y + 22 + 6y

-6y = 12 - 10 + 22

-6y = 24

y = -4

Answer: C. Jamaal added 4 and 9 to the right hand side in step 4; he should have added 16 and 36. The radius is r=8.

Step-by-step explanation: edge 2020, i took one for the team boys :(

In the given conic equation, Jamaal added 16 and 36 on the left hand side. However, he added 4 and 9 on the right hand side. The radius is r = 8.

What is a general conic equation?

Ax² + Bxy + Cy² + Dx + Ey + F = 0, where x, y are variables and A, B, C, D, E, F are constant terms.

Given,

4x² + 4y² – 16x + 24y – 12 = 0

⇒ 4x² – 16x + 4y² + 24y = 12

⇒ 4(x² – 4x) + 4(y² + 6y) = 12

⇒ 4(x² – 4x) + 16 + 4(y² + 6y) + 36 = 12 + 16 + 36

⇒ 4(x² – 4x + 4) + 4(y² + 6y + 9) = 12 + 16 + 36

⇒ 4(x – 2)² + 4(y + 3)² = 64

⇒ 4(x – 2)² + 4(y + 3)² = (8)²

Therefore, the center is at (2, -3) and the radius is r = 8.

Jamaal must have added 16 and 36 on the rest hand side of the conic equation. That's the mistake Jamaal did. As a result, the value of the radius is wrong when Jamaal solved.

Shelby's new weekly wage would be £318.50  if she receives a pay increase  of 45p per hour.

What is Shelby's hourly rate based on the  weekly wage of £302.75?

Shelby's hourly rate can be determined as her weekly wage divided by the number of hours spent working per week, in essence, the hourly rate is based on the weekly wage and the number of hours since the total weekly wage can as well be determined as the hourly rate multiplied by the number of hours working per week

hourly rate=weekly wage/hours spent working per week

weekly wage=£302.75

hours spent working per week=35

hourly rate=£302.75/35

hourly rate=£8.65

her new hourly rate=£8.65+£0.45

her new hourly rate=£9.10

new weekly wage=35*£9.10

new weekly wage=£318.50

The Maclaurin series of ln(1 − x) is f(x) =  ∑xⁿ⁺¹/(n+1) + c

A Maclaurin series is a Taylor series expansion of a function about 0,

f(x) = f(0) + xf'(0) +  x²f''(0)/2! + x³f⁽³⁾(0)/3! +.... xⁿf⁽ⁿ⁾(0)/n! ...

We have been the given function

⇒ f(x) = ln(1 − x)

First, let us find the derivative of f(x) for the Maclaurin series,

f'(x) = 1/(1 − x) =  1/(1 − x)

⇒ 1/(1 − x) = 1 + x + x² + x³⋯ = ∑xⁿ  if -1< x <1

f'(x) =  ∑xⁿ  if -1< x <1

By integrating using Power Rule,

⇒ f(x) = ∫∑xⁿ  if -1< x <1 = ∑xⁿ⁺¹/(n+1) + c

Since f(0) = ln(1 − 0) = 0

So ln(1 − x) =  ∑xⁿ⁺¹/(n+1) + c

Hence, the Maclaurin series of ln(1 − x) is f(x) =  ∑xⁿ⁺¹/(n+1) + c

the area of the yellow figure is 45 square units.

The figure shaded in yellow can be decomposed in two simpler ones, a triangle of base of 4 units and height of 5 units, and a rectangle of 5 units by 7 units.

The area of the triangle is:

A = 4*5/2 = 10 square units

The area of the rectangle is:

A' = 5*7 = 35 square units.

Adding that we get:

A + A' = 10 square units + 35 square units = 45 square units.

Then the area of the yellow figure is 45 square units.

domain is x numbers and that has all the x numbers in it

The value of domain in the given function is ( -4, 0 , 1, 2).

The value of range in the given function is ( 1, -3, -4 ).

Given,The function {(0,1), (1,-3), (2,-4), (-4,1)}

We have to find ,

Domain and range of the given function .

The domain of a function is the complete set of possible values of the independent variable.

So, The value of domain in the given function is ,

Domain = ( -4, 0, 1,  2 )

And, The range of a function is the complete set of all possible resulting values of they,  dependent variable (usually), after we have substituted the domain.

So, The value of range in the given function is

0.00016 is the distance of 8km if measured on a map with a scale of 1;50,000

Since the problem is in proportion, we can write it as an equation

like this,

1/50,000 = x/8

From here on we will cross-multiply

1/50,000 = x/8

50,000x = 8

x = 8/50,000

x = 0.00016

The cross multiplication method is used to solve linear equations with two variables. The method of cross-multiplication is the simplest and most straightforward way of solving linear equations in two variables. When we have a pair of variables in a linear equation, we apply this strategy.

The procedure of multiplying two fractions, p/q and r/t, by each other is known as cross multiplying or cross-multiplication. For example, p/q and r/t are two fractions that can be cross multiplied by multiplying p t and q r
