Answer:

1. r(x) = [q(x)]/[p(x)] is x ≠ 0

2. r(x) = p(x) * q(x) is All real numbers

3. r(x) = [1]/[p(x) + 16q(x)] is x ≠ -2

4. r(x) = [q(x)]/[p(x) + 2] is x ≠ -1

5. r(x) = [1]/[p(x) - q(x)] is x ≠ 1, 2

Answer:

19 square cm

Step-by-step explanation:

4 + 2.5 = 6.5

4 × 6.5 = 26

Since the shape is half of the product above, we're going to divide it by 2

26 ÷ 2 = 13

4 × 3 = 12

12 ÷ 2 = 6

Now to add them together

13 + 6 = 19

Answer:

(x + 1)(x + 3)eˣ

Step-by-step explanation:

Since f(x) = (x + 1)²eˣ

df(x)/dx = d[(x + 1)²eˣ]/dx

By the product rule, duv/dx = udv/dx + vdu/dx

where  u =  (x + 1)² and v = eˣ

So,  df(x)/dx = d[(x + 1)²eˣ]/dx

= (x + 1)²deˣ/dx + eˣd(x + 1)²/dx

= (x + 1)²eˣ + eˣd(x + 1)²/d(x + 1) × d(x + 1)/dx  (by the chain-rule dy/dx = dy/du × du/dx)

= (x + 1)²eˣ + eˣ[2(x + 1) × 1]

= (x + 1)²eˣ + 2eˣ(x + 1)

= (x + 1)eˣ(x + 1 + 2)

= (x + 1)eˣ(x + 3)

= (x + 1)(x + 3)eˣ

Answer:

1) linear

2) none of the above

Step-by-step explanation:

A linear function has a constant rate of change. The graph of any linear function is a straight line. If y = f(x) is a linear function, then for some constants b and m: y = b + mx.

Answer:

462.99

Step-by-step explanation:

Answer:

Your answer is 8.06.

Step-by-step explanation:

Since you're finding the hypotenuse of the triangle through Pythagorean theorem, you need to use the formula:

a² + b² = c²

Here, you have to remember that x is the same as c in the formula. c is the hypotenuse and x.

a is going to be your smallest leg, so in this case a = 4.

b is going to be your longest leg, so it is b = 7.

Now, you don't know what c yet is so you simply write it as:

4² + 7² = c²

Do the exponents.

16 + 49 = c²

Add.

65 = c²

Now you need to get the exponent away from the c. To do that, all you have to do is square root both sides.

√65 = √c2

Once you do that, you have your answer!

8.0622577483 = c

Now just simplify and you're done :)

Answer:

(0,1)

Step-by-step explanation:

Answer:

14 units

Step-by-step explanation:

Area is l*w and since the length is known, solve for width

182/13=13w/13

w=14

Answer:

14 units

Step-by-step explanation:

Given, the area of rectangle = 182 square units

length = 13 units

width = ?

By using the formula to find the area of a rectangle, we have

area of rectangle = length * width

182 = 13 * width

182/13 = width

14 units = width

Answer:

For the first one it is 5x+2

Step-by-step explanation:

(9x+5) - (4x+3) = ?

First you minus the x's together so,

9x-4x which would equal 5x

then you minus the 5 and 3 together so,

5-3 which would equal 2

then you put the 5x and the 2 together and you get

5x+2 :-)

For the rest of the problems, use this as an example!

With 2x-4 given to you, you can substitute x (input) and solve with that input to get y (output).

Ex. 2(0)-4=-4, (0, -4)

     2(1)-4=-2, (1, -2)

     2(2)-4=0, (2, 0)
