Answer:

4.2 units

Step-by-step explanation:

Assuming 1 grid box = 1 units, the coordinates of the two points are (-1, -1) and (2, 2).

Apply distance formula d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} to find the distance between (-1, -1) and (2, 2).

Let,

(-1, -1) = (x_1, y_1)

(2, 2) = (x_2, y_2)

Plug in the values

d = \sqrt{(2 - (-1))^2 + (2 - (-1))^2}

d = \sqrt{(3)^2 + (3)^2}

d = \sqrt{9 + 9}

d = \sqrt{18}

d = 4.2 (to the nearest tenth)

What is the frequency heard by a person driving at 15 m/s toward a blowing factory whistle (800. Hz) if the speed of sound is 34
bija089 [108]

Answer:

Answer:

835.29 Hz

Explanation:

When moving towards the source of sound, frequency will be given by

f*=f(vd+v)/v

Where f is the freqiency of the source, vd is the driving speed, v is the speed of sound in air, f* is the inkown frequency when moving forward.

Substituting 800 Hz for f, 340 m/s for v and 15 m/s for vd then

f*=800(15+340)/340=835.29411764704 Hz

Rounded off, the frequency is approximately 835.29 Hz

The price of a new computer is $1,449 at your local store. This is 18% less than what it costs at the Brownstone Mall. How much
Komok [63]

Given:

Price of new computer at local store = $1,449

This is 18% less than what it costs at the Brownstone Mall.

To find:

The cost of new computer at the Brownstone Mall.

Solution:

Let x be the cost of new computer at the Brownstone Mall.

According to the question,

x-18\%\text{ of }x=1449

x-\dfrac{18}{100}x=1449

x-0.18x=1449

0.82x=1449

Divide both sides by 0.82.

x=\dfrac{1449}{0.82}

x=1767.07317

x\approx 1767.07

Therefore, the cost of new computer at the Brownstone Mall is $1767.07.
