According to the given data we have the following:

3√45 -4 √225 + √200 - √50

Then to simplify we would have to make the following:

[3 × √3 × √3 × √5] - [√5 × √5 × √5] + [√2 × √2 × √2 × √5 × √5] - [√2 × √5 × √5]

=[3 × 3 × √5] - [5 × √5] + [2 × 5 × √2] - [5 × √2]

=3√5 - 5√5 + 10√2 - 5√2

=√5(3 - 5) + √2(10 - 5)

=(-2√5) + 5√2

Answer: p=110.1321 pounds

Step-by-step explanation:

50 divided by 0.454 is equal to 110.1321

The inverse of the function is [tex]f^-1 = \frac{1}{4}x + 2[/tex] .

What is inverse of the function ?

   A function that "undoes" another function is known as an inverse in mathematics. To put it another way, if f(x) produces y, then y will produce x when y is fed into f's inverse function. A function f is said to be invertible if it has an inverse, and the inverse is represented by the symbol [tex]f^-1[/tex]

Here the given function is,

=> f(x) = 2(x-3)2+4

=> f(x) = 4(x-3)+4

=> f(x) = 4x-12+4

=> f(x) = 4x -8

Now take y= f(x) then,

=> y = f(x)=4x-8

=> y = 4x-8

Now  interchange x and y then,

=> x = 4y-8

Now solve for y then,

=> x+8 = 4y

=> y= [tex]\frac{1}{4} x+ 2[/tex]

Then [tex]f^-1[/tex] = [tex]\frac{1}{4}x+ 2[/tex]

Therefore inverse of the function is [tex]f^-1 = \frac{1}{4}x + 2[/tex] .

Solution

Given the equation 2x+5y=1

We are required to Identify the slope and y intercept

The general equation of a straight line is in the form y = mx + c

Where m = slope and c= y-intercept

To solve the problem before us, we need to re-write 2x+5y=1 in the form y = mx + c

Thus, the slope = -2/5 while the y-intercept is 1/5

Answer: 1=x

Step-by-step explanation:

9-4x-4=3x-10+8x

9-4+10=3x+8x+4x

15=15x

1=x

Expand the brackets :
9 - 4x - 4 = 3x - 10 + 8x

-> 9 - 4x - 4 - (3x - 10 + 8x) = 0
-> 9 - 4x - 4 - 3x + 10 - 8x = 0
-> (9 - 4 + 10) - (4x + 3x + 8x) = 0
-> 15 - 15x = 0
15x = 15
x = 1

Might be confusing so just leave a comment if you don't understand (because I do the more detailed way really ;-;)

The probability that a customer purchased popcorn, given that they purchased from stand B is 13.4%.

For the given question;

The data for the selling of the snack items at arena are given;

Snack Item    Hot Dogs  Nachos Popcorn Total Concession

Stand A          125            65          40           230

Stand B          218            119          52           389

Stand C          65             52          13             130

Total              408           236        105           749

Now the customer purchased the popcorn from stand B.

Thus, total number of snack at stand B = 389

Total number of popcorn at stand B = 52

Thus,

Probability = favourable outcome/total outcome

Probability = 52/386

Probability % = 52/386 × 100

Probability % = 13.4%.

Thus, the probability that a customer purchased popcorn, given that they purchased from stand B is 13.4%.

We have 20 coins in total, lets say that we have X amount od quarters(0.25 dollar) and Y amount of dimes(0.1 dollar), and in total we have $3.05, with this we can write the system:

Wich means that we have 20 coins, and:

Thats the amount of money we have.

So, from the first equation, we can isolate X, as follows:

And with that we can substitute X in the second equation, as follows:

So, if Y=13, we have that X=7. So 13 dimes and 7 quarters.

The given system of equation are :

-6x - y = -16

-6x -5y = -8

On subtracting both the equation we get :

-6x -y -(-6x -5y) = -16 -(-8)

-6x -y +6x +5y = -16 +8

-6x + 6x +5y -y = -8

4y = -8

4y = -8

Divide both side by 4:

4y/4 = -8/4

y = -2

Substitute the value of y =- 2 in the any one equation:

-6x - y = -16

-6x - (-2)= -16

-6x + 2 = -16

-6x = -16 -2

-6x = -18

The value of sin Y is 4/5. The correct option is B) 4/5

From the question, we are to determine the value of sin Y.

From the given information, we have that

sin X = 3/5

and

cos X = 4/5

Also,

We have that angle X and angle Y are complementary angles.

That is,

X + Y = 90°

From the Trigonometric ratios of complementary angles, we have that

sin Y = cos (90° - Y)

From X + Y = 90°

X = 90° - Y

Therefore,

sin Y = cos X

From the given information,

cos X = 4/5
