Answer:

33

Step-by-step explanation:

Remember PEMDAS when using order of operations.

Parentheses Exponents Multiplication Division Addition Subtraction.

1. Solve what's in the parentheses first:

5+4 = 9

2. Multiply what's in the parentheses by 3.

9 x 3=27

3. Add 6

27+ 6 = 33

Answer:

1 cm = 100 mi

28.9/1=28.9

28.9 x 100 = 2890 miles distance

2890 / 65 miles per hour = 44.4615 hours to drive

44.461/24 hours in a day = 1.85 rounded up is 2 days

About two days

Minchanka [31]

The exponential function which represented by the values in the table is f(x)=4(\frac{1}{2})^{x} ⇒ 3rd answer

Step-by-step explanation:

The form of the exponential function is f(x)=a(b)^{x} , where

  • a is the initial value (when x = 0)
  • b is the growth/decay factor
  • If k > 1, then it is a growth factor
  • If 0 < k < 1, then it is a decay factor

The table:

→  x    :    f(x)

→ -2    :    16

→ -1     :    8

→  0    :    4

→   1    :    2

→   2   :     1

∵ f(x)=a(b)^{x}

- To find the exponential function substitute the value of x and f(x)

  by some values from the table to find a and b, at first use the

  point (0 , 4) to find the value of a

∵ x = 0 and f(x) = 4

∴ 4=a(b)^{0}

- Remember that any number to the power of zero equal 1

  except the zero

∵ b^{0}=1

∴ 4 = a(1)

∴ a = 4

Substitute the value of a in the equation

∴ f(x)=4(b)^{x}

- Chose any other point fro the table to find b, lets take (1 , 2)

∵ x = 1 and f(x) = 2

∴ 2=4(b)^{1}

∴ 2 = 4 b

- Divide both sides by 4

∴ b=\frac{2}{4}=\frac{1}{2}

- Substitute the value of b in the equation

∴ f(x)=4(\frac{1}{2})^{x}

The exponential function which represented by the values in the table is f(x)=4(\frac{1}{2})^{x}

EleoNora [17]

Answer:

<h3> X = 2 , X = -3</h3>

Option C is the correct option.

Step-by-step explanation:

f(x) = a {x}^{2}  + bx + c

Discriminant = {b}^{2}  - 4ac

Given d = 15

When discriminant D > 0 --> roots are real and distinct. ( unequal )

So , {3}^{rd} option has real and distinct roots.

Hope this helps..

Best regards!!
