the distance between (-1/2, -1) , (5/8, -1)

Answers

Answer 1

Solution :  Distance between (-1/2, -1) , (5/8, -1) = .75

Distance Formula :

Distance between two points can be evaluated if we know the c

[tex]\sqrt{{(y2-y1)^{2} } +(x2-x1)^{2}][/tex] = XY

The difference between the x-axis coordinates gives the horizontal distance and the difference between the y-axis coordinates gives the vertical distance.

Distance between the points P and Q is calculated as follows:

S and T are the points on the x-axis which are endpoints of two parallel line segments PS and QT respectively.

⇒ PR = ST

Coordinates of S and T are (x1, 0) and  (x2, 0) respectively.

OS =  x1 and OT = x2

ST = OT – OS = x2 – x1 = PR

Similarly,

PS =  RT

QR = QT – RT = QT – PS = y2 – y1

By Pythagoras theorem,

PQ2 = PR2 + QR2

PQ = √[(x2– x1)2+ (y2– y1)2]

Therefore,

Distance between two points (x1,y1) and (x2,y2) is given by:

[tex]\sqrt{{(y2-y1)^{2} } +(x2-x1)^{2}][/tex]

distance between (-1/2, -1) , (5/8, -1)

The evaluations of the quadratic equation at the values of 0, 7 and - 5 are 5, 1356 and - 460, respectively.

How to evaluate a polynomial function

In this question we have the definition of a quadratic equation, which has to be evaluated at three distinct values of x. Evaluating a function consists in substituting the independent variable by a value and simplify the expression. Now we proceed to evaluate the function:

f(0) = 4 · 0³ - 7 · 0 + 5

f(0) = 5

f(7) = 4 · 7³ - 7 · 3 + 5

f(7) = 1372 - 21 + 5

The Thai Pepper has a hotness rating of 7.5 x 10^4 on the Scoville scale.

The Red Savina Habanero has a hotness rating of 4.6 x 10^5 on the Scoville scale.

How many times hotter is the Red Savina Habanero than the Thai Pepper?

a
Divide (4.6 x 10^5) / (7.5 x 10^4) = (4.6 / 7.5) x (10^(5-4)) = .613 x 10^1 = 6.13 times hotter
b
Multiply (7.5 x 10^4) x (4.6 x 10^5) = (7.5 x 4.6) x (10^(4+5)) = 34.5 x 10^ 9 = 3.45 x 10^10
c
Divide (7.5 x 10^4) / (4.6 x 10^5) = (7.5 / 4.6) x (10^(4-5)) = 1.63 x 10^ 1 = 16.3 times hotter

What is ratio?

A ratio can be defined as the comparison of two or more numbers on the basis of their sizes in relation to each other;

Given that;

Thai Pepper has a hotness rating of 7.5 x 10^4 Red Savina Habanero has a hotness rating of 4.6 x 10^5

To determine the ratio, we have to divide Red Savina Habanero hotness rating by Thai Pepper hotness rating

This is represented as;

= 4.6 x 10^5 /  7.5 x 10^4

= 6. 13 times

The Red Savina Habanero is 6. 13 times hotter

By taking the quotient between the ratings, we can see that  Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

How many times hotter is the Red Savina Habanero than the Thai Pepper?

We know that the Thai Pepper has a hotness rating of 7.5*10⁴, while the Red Savina Habanero has a hotness rating of 4.6*10⁵.

We want to see how many times hotter is the Red Savina Habanero than the Thai Pepper, to find that we need to take the quotient between the rating for the Habanero and the rating for the Pepper.

It gives:

Q = (4.6*10⁵)/(7.5*10⁴)

This can be rewritten as:

Q = (4.6/7.5)*(10⁵/10⁴)

   =0.613*(10 ⁵⁻⁴) = 0.613*10

Now, we want to write this in scientific notation, so we need to have a single digit different than zero in the left side of the decimal point.

Then we can rewrite:

0.613*10 = 6.13*10⁰ = 6.13

We conclude that the Red Savina Habanero is 6.13 times hotter than the Thai Pepper.

Applying cross multiplication, the proportion can also be written as follows:

mq = pn.

Then each statement in which the application of cross multiplication results in this product is valid.

Thus the third, fourth, and fifth options are the correct options, as the application of the cross multiplication for each of them results in the expression mq = pn.

Suppose that two balls are selected with replacement from a bag that contains 10 white and 5 black balls. What is the probability that both balls are black?

Answers

The probability that both the balls are black is  [tex]\frac{1}{9} \\[/tex] .

Probability is the section of mathematics which deals with the likelihood of an event happening.

The value of probability is a fraction which always lies between 0 and 1. it is defined as the ratio of the favorable outcomes of an event to the total outcome of an event.

Given the bag has 10 white balls and 5 black balls. Therefore the total number of balls in the bag is 15 .

Hence the sample space is 15 .

The balls are drawn with replacement. Therefore for the first ball pick:

Number of favorable outcomes = 5

Total number of outcomes = 15

Probability = favorable outcome ÷ total outcome

Therefore  [tex]P_1=\frac{5}{15}=\frac{1}{3}[/tex]

Now the ball is placed back and the second ball is picked.

Number of favorable outcomes = 5

Total number of outcomes = 15

Probability = favorable outcome ÷ total outcome

Therefore  [tex]P_2=\frac{5}{15}=\frac{1}{3}[/tex]

Now the total probability that both the balls are black is :

P = P₁×P₂

[tex]P=\frac{1}{3}\times \frac{1}{3}\\\\P=\frac{1}{9}[/tex]

Hence the probability of picking two black balls is  [tex]\frac{1}{9} \\[/tex]  .

The rectangular coordinates of each point are (x, y) = (- √2, √2), (x, y) = (2√3, 2) and (x, y) = (- 1 / 3, - √3 / 3).

How to convert polar coordinates into rectangular form

Polar coordinates are of the form (r, θ), where r and θ are the the distance with respect to the origin and the direction in standard position. The coordinates in rectangular form can be described in polar terms by the following formula:

(x, y) = (r · cos θ, r · sin θ)

Now we find the polar coordinates equivalent to each pair of rectangular coordinates:

Case 1

(x, y) = (2 · cos (3π / 4), 2 · sin (3π / 4))

(x, y) = (- √2, √2)

Case 2

(x, y) = (- 4 · cos (7π / 6), - 4 · sin (7π / 6))

(x, y) = (2√3, 2)

Case 3

(x, y) = ((2 / 3) · cos (- 2π / 3), (2 / 3) · sin (- 2π / 3))

The flow rate of a hose, found by dividing the volume of water that leaves the hose in cubic yards during a period of time measured in seconds

Answers

The flow rate of the hose calculated mathematically is 0.0127425 m³/s.

What is defined as the flow rate?The amount of water which flows through a pipe per unit time is measured as its flow rate. It is typically calculated by dividing the volume of water by the total time it requires to flow. A pipe's flow rate is typically assessed in meters cubes per second as well as litres per second.

The flow rate of a pipe is determined by dividing this same volume of water leaving the pipe in cubic yards by the time in hours.

unit = cubic yard/ hours

The mathematical units are as follows:

1 cubic yard equals 0.764555 cubic meter.

The units in meters cubes per second are calculated as follows:

unit = 0.764555 cubic meter/60 seconds

unit = 0.0127425 cubic meter/ seconds
