what is quadratic formula?

The required equation which represents the expression of Celsius temperature as a linear function of the Fahrenheit temperature is; C = (9/5)F - 57.6.

It follows from the task content that the linear equation which relates both the Celsius and Fahrenheit temperature is to be determined.

On this note, the two points which can be inferred to describe the linear relationship are;

(32, 0) and (212, 100)

Hence, the slope of the linear equation;

m = (C2 - C1)/(F2 - F1)

m = (212 - 32)/(100 - 0)

m = 180/100

m = 9/5

Hence, from the point-slope equation form; (y-y1) = m (x -x1).

We have; (C - 0) = (9/5) (F - 32)

C = (9/5)F - 57.6

Answer: formula - (x/4)+x

Step-by-step explanation:

Since there are no numbers, here is just the formula and what it means :)

(x/4)+x

(btw x is whatever your number is)

so what you need to do first is to divide your number by 4 because 25% is 1/4 of 100%

and then add that number that you just got to your number.

Its a little confusing to say out in words, so here is an example using 24

24/4=6

24+6=30

and heres another example using 50

50/4=12.5

50+12.5=62.5

Answer: B) rose bush: $6, geranium $7

Step-by-step explanation:

Jose spent $70 on 7 rose bushes and 4 geraniums.

( 7 x $6 = $42 ) ( 4 x $7 =  $28 )

$42+$28= $70

Eugene spent $50 on 6 rose bushes and 2 geraniums.

( 6 x $6 = $36 ) ( 2 x $7 = $14 )

36+14 =50

Volume = PI x r^2 x h

r -s 1/2 the diameter ( 20/2 = 10)

Volume = 3.14 x 10^2 x 5

Volume = 3.14 x 100 x 5

Volume = 3.14 x 500

Volume = 1570 cubic meters

Considering that XZ is the perpendicular bisector of segment WY, we have that the value of k is of k = 6.

It means that XZ divides the segment into two segments of equal length, given by:

WX = XY.

From the lengths given, we can solve for k as follows:

3k + 17 = 7k - 7

4k = 24.

k = 24/4

k = 6.

The value of k is of k = 6.

Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

Selection of menu, food, clothes, subjects, the team are examples of combinations.

The formula for combinations is: nCr = n!/[r! (n-r)!]

nCr represents the number of combinations from “n” objects taken “r” at a time.

given that

select 6 restaurants from 11.

nCr = n!/[r! (n-r)!]

we are looking at a Combination of 11 things takes 6 at a time, or 11C6

11C6=11!/(6!5!)

11C6=11×10×9×8×7 / 5×4×3×2×1.

11C6=55440 / 120

11C6=462

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The real surface area is between 214.9 square inches and 668.3 square inches.

The mistaken surface area found by Jayden is 443 square inches.

In this problem we find a right angled parallelepiped whose dimensions are known. The surface area of the parallelepiped is the sum of the areas of the six faces. There are three pairs of faces with the following dimensions:

Pair 1

A' = (4.92 in) · (15.3 in)

A' = 75.276 in²

Pair 2

A'' = (15.3 in) · (7.28 in)

A'' = 111.384 in²

Pair 3

A''' = (4.92 in) · (7.28 in)

A''' = 35.818 in²

There are three pairs of faces with surface areas of 75.3 square inches, 111.384 square inches and 35.818 square inches.

The surface area of the six faces of the parallelepiped is equal to 444.956 square inches.

The range of measures for the area of the parallelepiped is represented by the following inequality:

6 · 35.818 in² < 444.956 in² < 6 · 111.384 in²

214.908 in² < 444.956 in² < 668.304 in²

The real surface area is between 214.9 square inches and 668.3 square inches.

Lastly, the mistaken surface area found by Jayden is:

A = 2 · (4.92 in) · (15.1 in) + 2 · (111.384 in²) + 2 · (35.818 in²)

A = 442.988 in²

The mistaken surface area found by Jayden is 443 square inches.

The 40th percentile is (1.6 + 1.6) / 2 = 1.6

What is percentile ?

In statistics, a k th percentile is a score below which a given percentage k of scores in its frequency distribution falls or a score at or below which a given percentage falls.

The data are in ascending order.

Compute the position of the pth percentile (index i):

i = (p/100)*n

i = (40/100)*50

i = 20

The index i is an integer ⇒ the 40th percentile is the average of the values in the 19th and 20th positions (1.6 and 1.6 respectively).

Therefore, the 40th percentile is (1.6 + 1.6) / 2 = 1.6

Answer:

The largest advertisement she can afford has dimensions of 5 in x 10/3 in

Step-by-step explanation:

Assume the dimensions of the advertisement are L and W.

The area of the advertisement is:

A = L.W

The ratio length/width is 3:2, thus the proportion is:

[tex]\displaystyle \frac{L}{W}=\frac{3}{2}[/tex]

Thus:

[tex]\displaystyle L=\frac{3}{2}W[/tex]

The area is:

[tex]\displaystyle A=\frac{3}{2}W^2[/tex]

Since the square inch of advertisement space sells for $3, the cost for Anna to purchase it is:

[tex]\displaystyle C=3\cdot\frac{3}{2}W^2[/tex]

Simplifying:

[tex]\displaystyle C=\frac{9}{2}W^2[/tex]

This cost can be a maximum of $50, thus:

[tex]\displaystyle \frac{9}{2}W^2=50[/tex]

Multiplying by 2:

[tex]9W^2=100[/tex]

Solving for W:

[tex]\displaystyle W=\sqrt{\frac{100}{9}}=\frac{10}{3}[/tex]

[tex]\displaystyle W=\frac{10}{3}[/tex]

And

[tex]\displaystyle L=\frac{3}{2}\cdot \frac{10}{3}[/tex]

L = 5

Thus the largest advertisement she can afford has dimensions of 5 in x 10/3 in
