Answers

Answer:

[tex]\sqrt{85}[/tex] units

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = N(- 9, 9) and (x₂, y₂ ) = H(- 3, 2)

What is the solution to the following equation? x2 + 3x + 4 = 0

Answers

Answer:

[tex]x=\dfrac{-3\pm \sqrt7i}{2}[/tex]

Step-by-step explanation:

The given equation is [tex]x^{2}+3x+4=0[/tex].

We need to find the solution of the above equation.

The solution of an equation [tex]ax^2+bx+c=0[/tex] is :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

We have, a = 1, b = 3 and c = 4

[tex]x=\dfrac{-3+ \sqrt{(3)^2-4(1)(4)} }{2}, \dfrac{-3- \sqrt{(3)^2-4(1)(4)} }{2}\\\\=\dfrac{-3+\sqrt{9-16}}{2}, \dfrac{-3-\sqrt{9-16}}{2}\\\\=\dfrac{-3\pm \sqrt7i}{2}[/tex]

So, the solution of the given equation is [tex]\dfrac{-3\pm \sqrt7i}{2}[/tex].

Tammy figured her math exam would be difficult unless she put in at
least 15 hours of study time to prepare. She studied 2½ hours on
Monday, 3 hours on Tuesday, 4¾ hours on Wednesday, and 4 ½
hours on Thursday. Did she study for at least 15 hours? Explain.

Answers

Answer: No, she did not study for at least 15 hours.

=======================================================

Explanation:

Fractions are often a pain, so I find it easier to convert to decimal form whenever possible.

1/2 = 0.5

3/4 = 0.75

which lead to,

2 & 1/2 = 2 + 1/2 = 2 + 0.5 = 2.5

4 & 3/4 = 4 + 3/4 = 4 + 0.75 = 4.75

4 & 1/2 = 4 + 1/2 = 4 + 0.5 = 4.5

-----------------------------

We can then rephrase the problem like so:

"She studied 2.5 hours on Monday, 3 hours on Tuesday, 4.75 hours on Wednesday, and 4.5 hours on Thursday"

Add up those decimal values to get:

2.5 + 3 + 4.75 + 4.5 = 14.75

In total, Tammy studied for 14.75 hours, which is equivalent to 14 & 3/4 hours.

This result is smaller than 15, so she did not study for at least 15 hours.

Note: "at least 15" is the same as saying "15 or more".

Answers

Answer:

The value of x = 40.

Step-by-step explanation:

From the figure, it is clear that given a transversal line cuts two parallel lines m and n, thus making the corresponding congruent angles 120° and 3x°.

Here, 120° is corresponding to 3x°.

As corresponding angles are congruent.

3x° = 120°

Divide both sides by 3

3x/3 = 120 / 3

x = 40

Therefore, the value of x = 40.

What are the vertices of triangle A'B'C' produced by (x, y) -> (x+5, y-2)?

Answers

Answer:

The vertices of triangle A'B'C' produced by (x, y) → (x+5, y-2) will be:

A'(8, -2) B'(8, 0) C'(5, -5)

Step-by-step explanation:

Given the vertices of an original triangle ΔABC such that

A = (3, 0)B = (3, 2)C = (0, -3)

As the rule of translation is given by

Translation: (x, y) → (x+5, y-2)

So, after the translation the vertices of the original triangle ΔABC will be translated as:

A = (3, 0) → (x+5, y-2) ⇒ (3+5, 0-2) = A'(8, -2)

B = (3, 2) → (x+5, y-2) ⇒ (3+5, 2-2) = B'(8, 0)

C = (0, -3) → (x+5, y-2) ⇒ (0+5, -3-2) = C'(5, -5)

Therefore, the vertices of triangle A'B'C' produced by (x, y) → (x+5, y-2) will be:

A'(8, -2) B'(8, 0) C'(5, -5)

I hope it will be useful.

The probability that a number selected at random in between integers from 3 to 30 inclusive is a multiple of 3 is .

What is probability?

The term probability indicates the chance of happening an event or incident.

The total integers between 3 to 30 inclusive is a multiple of 3 is:

{3, 6, 9, 12, 15, 18, 21, 24, 27, 30}

Therefore, favorable event = 10 numbers.

Here, sample space is:

{3, 4, 5, 6,......, 30} = 28 numbers

Therefore, required probability is

= (10 / 28)

A chemist is using 353 milliliters of a solution of acid and water. If 14.7 of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth

Answers

Answer:

The amount of Acid in a solution = 51.9 millimeters

Step-by-step explanation:

Given that the total amount of solution of acid and water = 353 milliliters

Acid percentage = 14.7%

Thus, in order to determine the amount of acid, all we need is to multiply 353 with 14.7% or 0.147.

i.e

Amount of Acid = 14.7% of 353

= 0.147 × 353

= 51.9 millimeters

Therefore, the amount of Acid in a solution = 51.9 millimeters
