The diameter of a circle is 12 ft. Find its area in terms of t.

Nadia says the hypotenuse of this right triangle has a length of 73 because the pythagorean theorem states that (28 45) squared

xxTIMURxx [149]

Both the options that Nadia gives are wrong about the length of hypotenuse.

Given length of hypotenuse is 73 and options which are :

1) Because the pythagoras theorem states that $28^{2} +45^{2}$ squared = 73 squared.

2) 3 squares are positioned to form a right triangle.

We have to choose the correct option which shows the calculation of length of hypotenuse.

Pythagoras theorem says that in a right angled triangle the square of hypotenuse of triangle is equal to sum of the square of base and square of perpendicular.

$H^{2} =P^{2} +B^{2}$

First option says that $28^{2} +45^{2} =73^{2}$

784+2025=5329

2809≠5329

so it is wrong.

Second option says that the length of hypotenuse is the sum of three squares but we have seen that the square of the length of hypotenuse is equal to sum of two square one is the square of base and the square of perpendicular.

Hence both the options are incorrect about the length of hypotenuse.

2. A book with a green sticker costs $2 less than half the price of a

Damm [24]

For this case we can propose an equation that will allow us to find the price of one of the books knowing the price of the other.

x: Let the variable that represents the price of the book with a green sticker

y: Let the variable that represents the price of the book with a yellow sticker

According to the statement we have:

$x = \frac {y} {2} -2\\$

$y=2(x+2)$

Finally, we can substitute the price of one of the books and clear the value of the other as the case may be.

Answer:

$x = \frac {y} {2} -2$

A roller coaster’s height is given by the equation h = –.025t2 + 4t + 50, where t represents the time in seconds. How long will

netineya [11]

The time it took the rider to reach the ground level is 171.651seconds

<h3>Quadratic functions</h3>

Quadratic functions are functions that has a leading degree of 2.

Given the equation that represents roller coaster’s height as shown

h = –0.025t^2 + 4t + 50

The coaster will reach the ground when h = 0

Substitute

0 = –0.025t^2 + 4t + 50

Factorize

On factorizing, the time it took the rider to reach the ground level is 171.651seconds

The difference of two numbers is 2. The sum of the same two numbers is 6. Find the numbers. Write the numbers from least to grea

Nady [450]

Answer:

2 and 4

Step-by-step explanation:

It says it on the correct answer box.

The difference in two numbers is 2.

2 and 4 are two numbers away from each other.

The sum of the same two numbers is 6.

2+4=6

In least to greatest order they would be written 2, 4
