The table shows the location of four cities relative to sea level.
Which city is closest to sea level? Explain.
City Location Relative to Sea Level
A –0.25 meter
B 74 meters
C −32 meters
C 0.5 meter


City A; –0.25 is closest to 0 on a number line.


City B; 74 has the greatest absolute value.


City C; −32 is farthest from 0 on a number line.


City D; 0.5 has the least absolute value.

The location of point D on the number line is -5.15625

The given parameters are:

A = 5

B = -10

AC : CB = 1 : 3

This means that

C = AC/(AC + AB) * (A - B)

This gives

C = 1/4 * (5 + 10)

Evaluate

C = 3.75

Also, we have:

BD : DC = 3 : 5

So, we have:

D = BD/(BD + DC) * (B - C)

This gives

D = 3/8 * (-10 - 3.75)

Evaluate

D = -5.15625

Hence, the location of point D on the number line is -5.15625

By using the given pair of values we can see that the constant of proportionality is 8, and the proportional relation is:

y = 8*x

A proportional relation is a linear relation with an y-intercept of 0, so these are written as:

y = a*x

Where a is the constant of proportionality.

By knowing a pair of values x and y, we can find the value of a. In this case we can see that when x = 3, y = 24, replacing that in the general equation we get:

24 = a*3

24/3 = a = 8

Then the constant of proportionality is 8, and the proportional relation is:

y = 8*x

The equation of the line in function notation is y.=-2x + 5

The standard equation of a line is expressed as y = mx + b

where

m is the slope

b is the y-intercept

Given the equation

2y=x-4

y = 1/2x - 2

The slope perpendicular will be -2

Substitute into y-y₁ = m(x-x₁)

y-(-7) = -2(x-6)

y+7 = -2x +12

y = -2x  + 5

Hence the equation of the line in function notation is y.=-2x + 5

Answer:

y = −2x + 8

Step-by-step explanation:

y = −2x + 8, the answer is this because, in order to find the slope, you must use the formula y2-y1/x2-x1, and the y-intercept is found by using the formula y=mx+b, in which b is the y-intercept which leads to the awnser,  y = −2x + 8.

Hi! Your answer is y = −2x + 8

Step-by-step explanation:

In order to find the slope, you have to use y2-y1/x2-x1 for the formula. The y-intercept can be found by using the formula y=mx+b. This means b is the y-intercept which makes the answer:  y = −2x + 8.

Step-by-step explanation:

In 1, is 4. Okay, this a good answer.

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.

Given the data in the question;

Since Q is a point between P and R.

PR = PQ + QR

Plug in the given values and solve for x.

5x - 3 = ( 2x + 8 ) + ( x + 11 )

5x - 3 = 2x + 8 + x + 11

5x - 3 = 3x + 19

5x - 3x = 19 + 3

2x = 22

x = 22/2

x = 11

Numerical value of segment PQ when x = 11 will be;

PQ = 2x + 8 = 2(11) + 8 = 30

Numerical value of segment QR when x = 11 will be;

QR = x + 11 = (11) + 11 = 22

Numerical value of segment PR when x = 11 will be;

PR = 5x - 3 = 5(11) - 3 = 52

Given that Q is a point between P and R, the numerical values of x, segment PQ, QR and PR are 11, 30, 22 and 52 respectively.

The height of the building = 1026.328ft

Given the angle of elevation = 11°

The angle of elevation is the angle formed between the horizontal distance to the base of the building and the line of sight to the top of the building.

We know that tan x = opposite side/adjacent side.

Here the opposite side gives the height of the building and the adjacent side is the distance to the base of the building on the ground.

Distance to the base of the building on the ground = 1 mile = 5280 ft.

So tan 11° = h/5280

⇒ h= tan 11° x 5280 = 0.194 x 5280 = 1026.328 ft

So the height of the building = 1026.328 ft

The answer is most probably to round the the numbers to nearest 10 digits and multiply

697x82 =  56,154

700 x 80 = 56000

A rounded number is less precise but roughly equal to the original number in value.

To the closest hundred, 341 is equivalent to 300. This is due to the fact that 341 is more similar in value to 300 than to 400. Because $1.89 is closer to $2.00 than to $1.00, when rounded off to the nearest dollar, it becomes $2.00.

Answer:

x² + y² = z²

Step-by-step explanation:

(a)

Using the right triangle altitude theorem,

x/z = p/x

x² = pz

(b)

y/z = q/y

y² = qz

(c)

x² + y² = pz + qz

x² + y² = z(p + q)

z = p + q

x² + y² = z × z

The factors of the expression is 3x²(x+5)(x+5) .

Factors of a number are defined as the numbers which divide the given number completely.

For an algebraic expression the factors of the expression are smaller polynomials which divide the given expression completely.

Factors of algebraic expression can be  calculated by the following methods:

The given polynomial is of the form:

3x⁴ + 30x³ + 75x²

Taking 3x² common from all the terms we get:

3x² (x² + 10x + 25)

Now we use middle- term factorization method to factor (x² + 10x + 25)

3x² (x² + 5x + 5x + 25)

or, ( 3x² ){x ( x + 5 ) + 5 ( x + 5 )}

Part a: The size of the game in standard form is 240000 kilobytes

Part b: The game was 5 times larger than the patch file

Part A:

Size of the game downloaded by Ryan on his computer = 2.4 * 10^5

Size of the patch file for the game = 48000 kilobytes

Therefore, converting the size of the game into the standard form:

Size of the game = 2.4 * 10^5

= 2.4 * 100000

= 240000 kilobytes

Therefore, the size of the game is 240000 kilobytes in standard form

Part B:

Size of the game = 240000 kilobytes

Size of the patch file = 48000 kilobytes

Computing the size of the game with respect to the patch file we get:

=240000/48000

The food budget is modeled by 0.5|x - 110| = 6

So, we have:

0.5|x - 110| = 6

Divide both sides by 0.5

|x - 110| = 12

Remove the absolute bracket

x - 110 = 12 and x - 110 = -12

Add 110 to both sides

x = 112 and x = 98

The probability that the product of the two rolls is a multiple of 3 is 1/2.

Probability:

Probability mean the fraction of the possibility of the required event.

The formula for the probability is

P(E) = n(E)/n(S)

Where

P(E) = Probability of the event

n(E) = number of required event

n(S) = Total number of event

Given,

Juan rolls a fair regular octahedral die marked with the numbers 1 through 8.

Then Amal rolls a fair six-sided die.

Here we need to find the  probability that the product of the two rolls is a multiple of 3.

We know that,

On both dice, only the faces with the numbers 3,6 are divisible by 3.

Let

P(a) = 2/8

P(a) = 1/4

it is  the probability that Juan rolls a 3 or a 6,

and Similarly,

P(b) = 2/6

P(b) = 1/3

Is the probability of Amal does.

By the Principle of Inclusion-Exclusion,

[tex]\[P(a \cup b) = P(a) + P(b) - P(a \cap b) = \frac{1}{4} + \frac{1}{3} - \frac{1}{4} \cdot \frac{1}{3} = \frac{1}{2} \Rightarrow \mathrm{(C)}\][/tex]
