Simplify √-48

1) -4√3

2) 4√-3

3) 4i√3

4) 4√3i

Answers

Answer 1

We can change the negative sign into i instantly as sqrt-1 is i.

With this the problem simplifies to sqrt48*i.

Now sqrt48=sqrt4*sqrt4*sqrt3=2*2*sqrt3

So the final product is 4sqrt3*i=4isqrt3.

Thus choosing choice 3 :)

Solve the equation:

7x − 2 = 26

Answers

Answer:

[tex] \large \boxed{x = 4}[/tex]

Step-by-step explanation:

Goal

Solve for x-term.

Given

Equation

[tex]7x - 2 = 26[/tex]

Step 1

Isolate x by adding 2 to both sides.

[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]

Step 2 (Optional)

We check the answer by substituting x = 4 in the equation.

[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]

The equation is true for x = 4. Hence, the solution is x = 4.

  P(Red) = 0.44

Step-by-step explanation:

There are 3 (mutually exclusive) ways to get red. The probability of red is the sum of the probabilities of the different ways to get there:

  P(red) = (0.35)(0.6) + (0.45)(0.2) + (0.20)(0.7) = 0.21 + 0.09 + 0.14 = 0.44

The probability a player will select a red ball is 0.44.

3x = 183
divide by 3 to both sides
x = 61

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.

Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.

As per the given data in the question,

Distance (d) traveled by the horse = 0.5 miles

Time (t) taken by the horse to cover the distance = 1.25 minutes

Then, the speed of the horse will be,

[tex]Speed=\frac{Distance}{Time}[/tex]

s = 0.5/1.25

s = 0.4 miles/minute.
