Answer:

a₂₁ = 41

Step-by-step explanation:

The nth term of an AP is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 1 and d = a₂ - a₁ = 3 - 1 = 2 , then

a₂₁ = 1 + (20 × 2) = 1 + 40 = 41

Can someone please help I’m very confused

Oxana [17]

y + 6 = 4/3(x - 2)

First, distribute the 4/3

y + 6 = 4/3x - 8/3

Subtract 6 from both sides.

y = 4/3x - 26/3

-26/3 is the y-intercept so start the graph at coordinate (0, -26/3)

After you plot the y-intercept, add 4 to they y-coordinate and 3 to the x-coordinate of the y-intercept to get the next point.

0 + 3 = 3

-26/3 + 4 = -14/3

The next point should be at (3, -14/3)

Add as many points as your professor requires.

Phoenix [80]

If in a certain recipe, a cake serving 6 persons require $2(\frac{1}{2} )$ cups of flour and Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use $3(\frac{1}{3})$ cups of flour.

As per the question statement, $2(\frac{1}{2} )$ cups of flour are required to bake a cake that serves 6. Mrs. Jenkins wants to use the same recipe to bake a cake for 8.

We have to calculate the number of cups of flours she will need to bake her desired cake as per the same recipe.

To solve this question, we will simply use the unitary method, i.e.,

A cake serving 6 required $2(\frac{1}{2} )=\frac{5}{2}$ cups of flour in its preparation, then,

A cake serving 1 person will require $\frac{\frac{5}{2} }{6} =\frac{5}{12}$ cups of flour, and finally,

A cake serving 1 person will require $(\frac{5}{12} *8)=\frac{10}{3}=3(\frac{1}{3})$ cups of flour.

Hence, Mrs. Jenkins wants to use the same recipe to make a cake for 8, then she will need to use $3(\frac{1}{3})$ cups of flour.

Unitary Method: In Mathematics, the unitary method is a problem-solving technique where, we first find the value of a single unit, and then calculate the necessary value by multiplying that single unit value.
