Answer 1

Answer:

See below

Step-by-step explanation:

Equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p

Given is the parabola:

(y + 1)^2 = (x + 2)

It has a vertex at (-2, -1)

New vertex (-1, -1) requires translation to the right by 1 unit. Which changes the function to:

(y + 1)^2 = (x + 2 - 1) ⇒ (y + 1)^2 = (x + 1)

For this function the focus and directrix is:

(y + 1)^2 = (x + 1)k = -1, p = 1/4, h = -1

Focus is

(h +p, k) = (- 0.75, -1)

Directrix is:

x = -1 - 1/4 = - 1.25

the X-intercepts are the places where the line crosses the x axis which is the one that goes along so they would be 5 and -5.
the Y-intercepts is the place where the lines cross the y axis which is the one that goes up. so for this question it is 5.

The pH of stomach acid is 2.7. Which of the following is the closest to the hydrogen concentration?

Answers

Answer:

0.002M

Step-by-step explanation:

2.7= -log(H^+)

-2.7=log(H^+)

10^-2.7 M=H^+

0.0002M=H^+

The stomach has an acidic fluid that is an important part of the digestive juices. The pH of 2.7 in the stomach is close to a 0.002M concentration of hydrogen.

What is pH?

pH measures the concentration of the hydronium and the hydrogen ions in the solution. pH is calculated as:

pH = -log (H⁺)

Here, pH = 2.7

Substituting values:

2.7 = -log (H⁺)

-2.7 = log (H⁺)

H⁺ = 10⁻²⁷ M

H⁺ = 0.0002M

Therefore, 0.002M is the concentration of hydrogen.

How many different ways can five types of laser printer be displayed on .1 shelf in a computer store? There are_______ different ways to display the five types of laser printer on a shelf.

Answers

Answer:

120 ways

Step-by-step explanation:

This is a pretty straightforward question. We are asked how many ways can 5 printers be displayed on one shelf. We use the formula of factorial in getting the number of ways, i.e

n! = n * (n-1) * ..... 1, in the question given, our n = 5, so if we plug it in, we get

n! = 5 * (5-1) * (4-1) * (3-1) * (2-1) * 1

n! = 5 * 4 * 3 * 2 * 1

n! = 120.

Thus, there are 120 different ways to display the five types of laser printer on a shelf.

During a war, Country A led a massive assault on the beach of Country B. The beach is 6.4 miles long. At 5 AM, a ship was first spotted from either end of the beach. The angle made with the ship from one end of the beach was 47°. The angle made with the ship from the other end of the beach was 71°. Determine the distance from the ship to either end of the beach at the moment the ship was first spotted.

Answers

Answer:

5.3 miles & 6.85 miles

Step-by-step explanation:

To solve this question, I would use the sine rule

a/Sine A = b/Sine B = c/Sine C

Making a rough sketch, I have a scalene triangle with angles 47° and 71°, by default, the third angle is 61°

Given that, from my rough sketch

Angle C = 62°

Angle B = 71°

Angle A = 47°

Side c = 6.4 miles

We're looking for dudes a and b, applying our formula, we have

a/Sine 47 = 6.4/Sine 62

a/0.7314 = 6.4/0.8829

a/0.7314 = 7.25

a = 7.25 * 0.7314

a = 5.3 miles

b/Sine 71 = 6.4/Sine 62

b/0.9455 = 6.4/0.8829

b/0.9455 = 7.25

b = 7.25 * 0.9455

b = 6.85 miles

If the mFT 3x - 2 and the mFE = 5x + 1, Find x and mTE. (GT is median)
Please get back to me soon, I'll give Brainliest!​

Answers

Answer:

x = 5

TE = 13

Step-by-step explanation:

Since GT is the median, then 2*(FT) = FE.

FE = 5x + 1

FT = 3x - 2

Therefore:

2*(3x - 2) = 5x + 1 (substitution)

6x - 4 = 5x + 1

Collect like terms

6x - 5x = 4 + 1

x = 5

TE = ½*(FE)

TE = ½*(5x + 1)

Plug in the value of x

TE = ½*(5(5) + 1)

TE = ½(25 + 1) = ½(26)

TE = 13

Read the excerpt from The Riddle of the Rosetta Stone by James Cross Giblin. De Guignes guessed rightly that the cartouches in hieroglyphic inscriptions were intended to draw attention to important names, probably the names of Egyptian rulers. Along with such insights, de Guignes advanced other ideas about the hieroglyphs that were as silly as any that had been proposed by Kircher or Horapollo. After comparing some Egyptian hieroglyphs with examples of Chinese picture writing, de Guignes announced that settlers from Egypt must have colonized China in ancient times. What ideas of de Guignes differed sharply from the authors? Egyptian society used picture writing. Chinese society used hieroglyphs. Cartouches were part of hieroglyphic inscriptions.
