So your answer is A.

quester [9]3 years ago

Answer:

A

Step-by-step explanation:

(2x^2 + 3x - 4) (x + 4)


FOIL.


2x^2 times x = 2x^3

3x times x is 3x^2

-4 times x = -4x

2x^2 times 4 = 8x^2

3x times 4 = 12 x

-4 times 4 = -16


Combine like terms to get 2x^3 + 11x^2 + 8x - 16.

Represent, the set of numbers between 5 to 50 when they are divided by 8 then the remainder is 3,It by description method, listi
Debora [2.8K]

By descriptive method = Set A is a set of all natural numbers between 5 and 50 which gives remainder 3 when divided by 8.Listing method : A = { 11, 19, 27, 35, 43} and Set builder method : A = { x : x ∈ N, x = 8 c + 3 and 1 < c < 5

We are given that:

Number range 5 - 50

Remainder = 3 when the number is divided by 8

We need to find the sets of numbers between 5 to 50 when they are divided by 8 gives remainder 3 by description method, listing method and set builder method.

Let the set be A

Descriptive Method

Set A is a set of all natural numbers between 5 and 50 which gives remainder 3 when divided by 8.

Listing Method

A = { 11, 19, 27, 35, 43}

Set Builder Method

A = { x : x ∈ N, x = 8 c + 3 and 1 < c < 5

Therefore, we get that, by descriptive method = Set A is a set of all natural numbers between 5 and 50 which gives remainder 3 when divided by 8.Listing method : A = { 11, 19, 27, 35, 43} and Set builder method : A = { x : x ∈ N, x = 8 c + 3 and 1 < c < 5

Using the equation representing the height of the firework (h = -16t2 + v0t + h0), algebraically determine the extreme value of
lubasha [3.4K]
-16t^2 + v0t + h0

=  -16(t^2 - 1/16 v0t)  + h0
 = -16 [(t - 1/32v0)^2 - (1/32 v0)^2 ) + h0
 = -16(t - 1/32v0)^2 + 1/64 (v0)^2 + h0   which is the vertex form 

The vertex  is at the point (1/32v0, 1/64 (v0)^2)

1/32v0  represents the time  when the firework is at its maximum height and 1/64 (v0)^2  is this maximum height

Liam uses 2 quarts of yellow paint and adds 3 1/4 Jars of blue paint.Evan uses 1/2 quarts of yellow paint and adds 5 1/2 of red
EleoNora [17]

Answer:

2 + (13/4)x = 1/2 + (11/2)y

Step-by-step explanation:

Let each jar of paint used by Liam be x

Let each jar of paint used by Evan be y.

Liam uses 2 quarts of yellow paints and adds 3 1/4 jars of blue paint. so we have

2 + 3 1/4x

= 2 + (13/4)x

Since Evan also uses 1/2 quarts of yellow paints and add 5 1/2 jar of red paint, we have

1/2 + 5 1/2y

= 1/2 + (11/2)y

Since they end up with the same volume of paint, we have

2 + (13/4)x = 1/2 + (11/2)y
