Answer:

B

Step-by-step explanation:

The Pythagoras theorem states that [tex]c^{2} = a^{2} + b^{2[/tex], where [tex]c[/tex] is the hypotenuse and a and b are the adjacent and opposite sides of the hypotenuse. If we made [tex]a[/tex] the subject of the expression, the expression will be re-written as [tex]a^{2} = c^{2} - b^{2}[/tex], which is the correct answer.

Accordingly the answer is Nineteen Fourths.

Step-by-step explanation:

Answer:

a - 6%

b - $7.50

Step-by-step explanation:

The answer for a

the only items that had sales tax were $3.00 and $0.50. The total tax for the both was $0.21 so you can find what percent 0.21 is of 3.00 + 0.50 o 3.50. Do this by dividing the percent you are looking for, 0.21, by what it is the percent of 3.50. 0.21 / 3.50 = 0.06. then you multiply the number you got, in this case 0.06 by 100 to find the percentage so it is 6%

The answer for b

Here you can just take the subtotal, $13.00, and subtract all the other prices and you will be left with the price of the top. 13.00 - 3.00 - 2.00 - 0.50 = 7.50. So the answer is $7.50

Answer:

So......cheating eh? jk, the answers 15

Step-by-step explanation:

you plug in 15 for x ==> 2/3 x 15 + 5 = f(15)

simplify ==> 10+5 = f(15)

so f(15) = 15

Answer:

not linear

Step-by-step explanation:

a linear function contains x and y only with the exponent 1.

this allows the function to be a line (hence the term "linear"), a constant ratio of y changes to x changes for any values of x which defines linear relation between x and y.

but this equation contains a term with x², which changes the size of change of y for every value of x.

e.g. when x changes by 1 from 1 to 2, y changes by 3 from 1² to 2² (1 to 4). but if x changes again by 1 from 2 to 3, y changes by 5 from 2² to 3² (4 to 9).

this is clearly not constant.

Answer:

y= 2x-3

when X= -1

y= 2(-1)-3

y= -2-3

y= -5

The value of the given function y=2x-3 is  -5 when x=-1

A function is a correspondence from the two set A to set B in which each element of set A has a unique image in B. Generally we denote a function by f or y.

Here the given function is y=2x-3

Putting x= -1 in the given function y=2x-3 , we get

y= 2(-1) -3

y= -2-3

y= -5

Hence the value of the function y= 2x-3 is -5 when x=-1 .

Answer:

100:100

Step-by-step explanation:

100 reds and 100 blues are in there

Answer:

x = 4

y = 12°

Step-by-step explanation:

Since each angles are equal ,

So each angle is 60°.

=> 5y = 60°

=> y = 60/5°

=> y = 12°

Again all sides will be equal ,

=> 5x - 6 = 3x + 2

=> 5x - 3x = 6+2

=> 2x = 8

=> x = 4

Answer:

It's a parabola with a minimum.

C(x)= 500,000 + 80x + 0.003x^2

C'(x) = 80 + 0.006x = 0

x = 80/0/006 = 13,333 units

Step-by-step explanation:

A company that produces chemicals used in manufacturing sells a certain product for $200 per unit. The total production cost for the product is

C(x)= 500,000 + 80x + 0.003x^2

The company can produce no more than 30,000 units during a given time period. How

many units of the chemical product should be manufactured and sold to maximize profit?

Answer: x = 3.030631 approximately

Explanation:

If you want to solve for x, then you could follow these steps:

[tex]18 = 1.57*x^{2.2}\\\\18/1.57 = x^{2.2}\\\\11.464968 \approx x^{2.2}\\\\x^{2.2} \approx 11.464968\\\\x \approx (11.464968)^{\frac{1}{2.2}}\\\\x \approx 3.030631\\\\[/tex]

In the second to last step, we have the value 11.464968 raised to the exponent of 1/(2.2) which is done to undo the exponent of 2.2 in the previous line.  The rule used is [tex]a^b = c \to a = c^{1/b}[/tex]

Answer:

PX : XQ = 2 : 5

Step-by-step explanation:

Since RX is perpendicular to PQ , then

Δ RPX and Δ RQX are right triangle

Calculate PX and XQ using Pythagoras' identity in the right triangles

PX² = 20² - 16² = 400 - 256 = 144 ( take square root of both sides )

PX = [tex]\sqrt{144}[/tex] = 12

Similarly

XQ² = 34² - 16² = 1156 - 256 = 900 ( take square root of both sides )

XQ = [tex]\sqrt{900}[/tex] = 30

Then

PX : XQ = 12 : 30 = 2 : 5 ( in simplest form )

Answer:

P = a + b + c

P = (8x + 2) + (5x - 4) + (9x + 3)

P = 8x + 5x + 9x + 2 - 4 + 3

P = 22x + 1

Using the principle of probability, the likelihood that Shreya wins by getting 2 blues and 1 red is 0.416

Creating an area model for the first two spinners :

___ G _ B _ B _ R _R _R

R_RG_RB_RB_RR_RR_RR

R_RG_RB_RB_RR_RR_RR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

B_BG_BB_BB_BR_BR_BR

G_GG_GB_GB_GR_GR_GR

G_GG_GB_GB_GR_GR_GR

Creating an area model or tree diagram for the third spinner would result in a sample space of (48 × 12) = 576 combinations.

However, the probability that Shreya would win can be obtained thus :

To win he needs to pick get 2 blues and 1 red in any order :

3! = 3 × 2 × 1 = 6 ways

P(BBR) = 1/3 × 4/8 × 5/12 = 0.0694444

P(winning) = 6 × 0.0694444 = 0.416

Therefore, the probability that Shreya wins is 0.416.

Answer:

(3,5)

1/3

Step-by-step explanation:

The equation is already in point-slope form. Therefore, both the point and slope can easily be found in the equation. Point slope form looks like [tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]. In this the point is [tex](x_{1},y_{1})[/tex] and the slope is m. So, the x value is 3 and the y value is 5, making the coordinate (3,5). Finally, the slope is 1/3.
