Answer:

see explanations below.

Step-by-step explanation:

Your answers are basically correct, but unfortunately the values between C and D have been inverted in both cases.

For the translation problem, the coordinates are:

A'(-4,2), B'(-2,4), C'(-2,0), D'(-4,0)

using the rule (x,y) -> (x-3, y+2)

For the reflection problem, the coordinates are

A'(5,4), B'(2,4), C'(2,1), D'(5,1)

using the rule (x,y)->(-x,y)

Also, note that letters for images have an appostrophe added, so you could add them on in the transformed images.

rusak2 [61]

Answer:

37.8metres

Step-by-step explanation:

The arc of the arrow can be modeled by the equation:

y=-0.02x²+0.65x+4

Where x is the horizontal distance (in meters) from Linda and y is the height (in meters) of the arrow.

The arrow hits the ground when its height (y) is zero.

Therefore, we determine the value(s) of x for which:

y=-0.02x²+0.65x+4=0

Using a calculator to solve the quadratic equation:

x=37.79 or -5.29

Since the distance cannot be a negative value, we ignore -5.29.

The distance from Linda when the arrow hits the ground is 37.8metres (to the nearest tenth)

Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:
Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

5p+3p+(-9)

We need to find an expression which is equivalent to the given expression.

Combine like terms.

(5p+3p)-9

8p-9

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

3(p+(-3))+5p

3(p-3)+5p

Using distributive property, we get

3p-9+5p

Combined liker terms.

(5p+3p)-9

8p-9

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.

a rectangle has a height of n3+4n2+3n and a width of n^3+5n^2 express the area of the entire rectangle
alukav5142 [94]

<u>Given</u>:

It is given that the height of the rectangle is n^3+4n^2+3n

The width of the rectangle is n^3+5n^2

We need to determine the area of the entire rectangle.

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=height \times width

Substituting the values, we have;

A=(n^3+4n^2+3n)(n^3+5n^2)

Multiplying each term within the parenthesis, we get;

A=n^{3} n^{3}+n^{3} \cdot 5 n^{2}+4 n^{2} n^{3}+4 n^{2} \cdot 5 n^{2}+3 n n^{3}+3 n \cdot 5 n^{2}

Simplifying, we get;

A=n^{6}+5 n^{5}+4n^{5}+20 n^{4}+3  n^{4}+15 n^{3}

Adding the like terms, we have;

A=n^{6}+9n^{5}+23 n^{4}+15 n^{3}

Thus, the area of the entire rectangle is n^{6}+9 n^{5}+23 n^{4}+15 n^{3}
