Answer:

The coefficient of n² is 3

Step-by-step explanation:

Given: $4n^3+3n^2+2n+1$

We are given an expression. We need to find the coefficient of n².

Coefficient is a constant number front of variable (n²)

$\text{Coefficient of }n^3\rightarrow 4$

$\text{Coefficient of }n^2\rightarrow 3$

$\text{Coefficient of }n\rightarrow 2$

1 is constant term of the expression.

A number front of n² is 3.

Hence, The coefficient of n² is 3

Nancy's garden has the dimensions shown 4 1/2 yard 3 3/4 yd . She need find the area

Marina86 [1]

Answer:

The area of Nancy's garden is $16\frac{7}{8}\ yd^{2}$

Step-by-step explanation:

I assume that the Nancy's garden is a rectangle shape

To find the area first convert mixed number to an improper fraction

$4\frac{1}{2}\ yd=\frac{4*2+1}{2}=\frac{9}{2}\ yd$

$3\frac{3}{4}\ yd=\frac{3*4+3}{4}=\frac{15}{4}\ yd$

Therefore

The area is equal to

$A=\frac{9}{2}*\frac{15}{4}=\frac{135}{8}\ yd^{2}$

convert to mixed number

$\frac{135}{8}\ yd^{2=\frac{128}{8}+\frac{7}{8}=16\frac{7}{8}\ yd^{2}$

Answer:

A. Half of

B. Twice

C. greater than

Step-by-step explanation:

The median of the box plot is the middle line of the box, so for set a it is approximately ten and for set b it is approximately 20. 10 is half of 20 and 20 is twice as much as 10.

How do I graph the linear equation y=-1/2x + 4

shtirl [24]

Answer:

The Two points for the line $y =\frac{-1}{2}x+4$ are

point A( x₁ , y₁) ≡ ( 0 , 4)

point B( x₂ , y₂) ≡ (8 , 0)

The Graph is attached below.

Step-by-step explanation:

Given:

$y =\frac{-1}{2}x+4$ ........... equation of a line Given

Let the points be point A, and point B

To Find:

point A( x₁ , y₁) ≡ ?

point B( x₂ , y₂) ≡ ?

Solution:

For Drawing a graph we require minimum two points but we will have here.

For point A( x₁ , y₁)

Put x = 0 in the given equation we get

$y =\frac{-1}{2}0+4\\\\y=4$

∴ point A( x₁ , y₁) ≡ ( 0 , 4)

For point B( x₂ , y₂)

Put y= 0 in the given equation we get

$0 =\frac{-1}{2}x+4\\\\x=8$

∴ point B( x₂ , y₂) ≡ (8 , 0)

Therefore,

The points for the line $y =\frac{-1}{2}x+4$ are

point A( x₁ , y₁) ≡ ( 0 , 4) (blue color point on the graph)

point B( x₂ , y₂) ≡ (8 , 0) (green color point on the graph)

The Graph is attached below..
