Answer:15.70

Step-by-step explanation:The formula for the circumference is 2πr. Plug-in the number provided into the formula, since diameter is double the radius you just divide the 5 by 2 to get 2.5.

So, 2π2.5=15.70

2 time π =6.28

6.28 time 2.5= 15.70

A quadratic equation is an equation whose leading coefficient is of the second degree. The correct option is D.

A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.

Its roots are given as:

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

A.) x²−4x+1=0

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(-4) \pm \sqrt{(-4)^2 - 4(1)(1)}}{2(1)}\\\\x = \dfrac{4 \pm \sqrt{16 - 4}}{2}\\\\x = \dfrac{4 \pm \sqrt{12}}{2}[/tex]

x = 2 ± √3

B.) x²−18=0

    x² = 18

    x = √18

C.) x²+6x+7=0

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(6) \pm \sqrt{(6)^2 - 4(1)(7)}}{2(1)}\\\\x = \dfrac{-6 \pm \sqrt{36 - 28}}{2}\\\\x = \dfrac{-6 \pm \sqrt{8}}{2}[/tex]

x = -3 ± √2

D.) x²−6x+7=0

[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{-(-6) \pm \sqrt{(-6)^2 - 4(1)(7)}}{2(1)}\\\\x = \dfrac{6 \pm \sqrt{36 - 28}}{2}\\\\x = \dfrac{6 \pm \sqrt{8}}{2}[/tex]

x = 3 ± √2

Answer:

96 pages

Step-by-step explanation:

This is because she reads 16 pages per hour so we just multiply 16 by 6 hours. And we get 96 pages.

Answer:

B. 96 pages

Step-by-step explanation:

8 pages in 30 minutes.

16 pages in 60 minutes. ( 8 x 2 = 16 pages)

60 min = 1 hour

16 pages in 1 hour.

16 x 6 = 96 pages in 6 hours

Answer: 1,594,323

Step-by-step explanation:

No of leaves which falls daily on the first day = 1

No of days leaves falls = 14 days.

Solution:

No of leaves of day 1

= 1.

No of leaves on day 2

= 1*3

= 3

No of leaves of day 3

= 3*3

= 9

No of leaves of day 4

= 9*3

= 27

No of leaves on day 5

= 27*3

= 81

No of leaves on day 6.

= 81*3

= 243.

No of leaves of day 7

= 243*3

= 729

No of leaves on day 8

= 729 * 3

= 2187

No of leaves on day 9

= 2187 *3

= 6561

No of leaves on day 10

= 6561 * 3

= 19683

No of leaves on day 11

= 19683 * 3

= 59049

No of leaves on day 12

= 59049 *3

= 177147

No of leaves on day 13

= 531441

No of leaves on day 14

= 531441 * 3

= 1,594,323.

The number of leaves that would be on the ground on the 24th day of autumn would be 1,594,323

Jin (WWH) spends 18.55 for every 7 tacos he gets. That means he spends 18.55÷7 for every taco he gets.

18.55÷7 = 2.65

Now you need to find how much he spends for 15 tacos. If one taco is 2.65, you need to multiply 15 by 2.65 to find the price for 15 tacos.

2.65×15=39.75.

Jin will have to pay $39.75 for 15 tacos.

Answer:

2. Def of supplementary angles

3. Def of supplementary angles

Answer:

Step-by-step explanation:

Note: the question did not provide the quantity to work with, so we will assume some values, say quantity Q= 30

Generally, it is normal for the revenue to decrease when the price of a commodity increase, this is so that buyer will have to react to adjust to the change in price.

When price increase from $50 to $60, the total revenue will decrease

let say the quantity Q1=30 , and the new quantity after price increase is Q2=20

1. The revenue PxQ before price change will be

PxQ= P1xQ1=50*30

PxQ= $1500

1. The revenue PxQ after price change will be

PxQ=P2xQ2= 60*20

P2xQ2= $1200

This clearly shows that based on the assumed data, the total revenue will drop from1500 to 1200, a total of $300 in a decrease

The inverse of the function is:

f^-1(x) = {-1, 0, 1, 2} corresponding to x = {-2, 3, 8, 13}

Option C is the correct answer.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

To find the inverse of the function, we need to switch the x and y variables, and then solve for y.

So, we start by writing the function in terms of y:

y = f(x) = {-2, 3, 8, 13} corresponding to x = {-1, 0, 1, 2}

Now we switch the x and y variables:

x = f(y) = {-2, 3, 8, 13} corresponding to y = {-1, 0, 1, 2}

Next, we solve for y:

For x = -2, y = -1

For x = 3, y = 0

For x = 8, y = 1

For x = 13, y = 2

Therefore,

The inverse of the function is:

f^-1(x) = {-1, 0, 1, 2} corresponding to x = {-2, 3, 8, 13}

Step-by-step explanation:

Answer:

The value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]

Option C is correct.

Step-by-step explanation:

We need to find value of x

We are given Perpendicular = 8

Hypotenuse = x

and Ф= 45°

Using trigonometric identity

[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}[/tex]

Putting values and finding x

[tex]sin \theta=\frac{Perpendicular}{Hypotenuse}\\sin \ 45^o=\frac{8}{x}\\\frac{1}{\sqrt{2} }= \frac{8}{x}\\\frac{1}{\sqrt{2} }x=8\\x=8\sqrt{2}[/tex]

So, the value of x is : [tex]\mathbf{8\sqrt{2}}[/tex]
