Key Ideas:Finding a quadratic equation

Solving the Question

We're given:

Vertex= (-5,-5)Passes Through (-7,3)

One of the forms of a quadratic equation is vertex form:

[tex]y=a(x-h)^2+k[/tex]

a = vertical stretchh = horizontal translationk = vertical translation(h,k) is the vertex

Plug in the vertex:

[tex]y=a(x-h)^2+k\\y=a(x+5)^2-5[/tex]

Plug in the given point and solve for a:

[tex]3=a(-7+5)^2-5\\3=a(-2)^2-53=4a-5\\8=4a\\a=2[/tex]

What is the dividend when the divisor is 8 and the quotient is 96 with a remainder of 3?

Answers

The dividend when the divisor is 8 and the quotient is 96 with a remainder of 3 is 771.

What is a dividend?

The dividend in mathematics is the value that is divided by another value to obtain the result. The dividend is the starting point for any division method. The dividend is one of four critical components of the division process. It is the whole that is to be divided into equal parts.

A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another integer to produce n. In this case, n is also said to be a multiple of m.

In this case, the dividend will be:

= (96 × 8) + 3

= 768 + 3

= 771

To solve this problem, I'll use trigonometric functions,

The trigonometric function that relates the opposite side and the hypotenuse is sine

Formula

sin 48 = Opposite side / hypotenuse

hypotenuse = 105 ft

5. Which of the equations show x and y DIRECTLY proportional to each relationship? For every one that does provide the constant of proportionality

Answers

A direct proportional relation can always be express as an equation of the form:

[tex]y=kx[/tex]

where k is the constant of proportionality. (This means that y has to be the result of multiplying a number by x)

Now, let's see at the option we have.

a)

Solving the equation for y we have:

[tex]\begin{gathered} 2x+2y=0 \\ 2y=-2x \\ y=-\frac{2}{2}x \\ y=-x \end{gathered}[/tex]

Since we can write the equation in the form as a direct proportional relationship we conclude that option a shows a directly proportional relationship and that the constant is -1.

b)

For this case we have the equation:

[tex]x=.125y[/tex]

From it we already can see that this means that x is directly proportional to y and that the constatn of porportionality is 0.125.

Now if we want we can solve the equation for y, then we have:

[tex]\begin{gathered} y=\frac{1}{.125}x \\ y=8x \end{gathered}[/tex]

this equation shows that y is directly proportional to x and that the constant of proportionality is 8.

Notice that the the constant of proportionality changes if we write the relation as x directly proportional to y or if we write it as y directly proportional to x. Either way the relation express the same and it is directly proportional.

c) and d)

For this equations that we have a division in which one of the variables is the divisor (or the denominator); this means that the equation show a relation between x and y but their are not directly proportional. In fact this means that the equations show an inversely proportional relations.

[tex]\sin^2\theta+\cos^2\theta=1[/tex]

We can eliminate the parameter theta adding the square of the coordinates

[tex]\begin{gathered} \sin^2\theta+\cos^2\theta=1 \\ 6^2(\sin^2\theta+\cos^2\theta)=6^2 \\ 6^2\sin^2\theta+6^2\cos^2\theta=6^2 \\ (6\sin\theta)^2+(6\cos\theta)^2=6^2 \\ (6\sin\theta)^2+(2\cdot3\cos\theta)^2=6^2 \\ (y)^2+(2x)^2=6^2 \\ y^2+4x^2=36 \\ \frac{x^2}{9}+\frac{y^2}{36}=1 \end{gathered}[/tex]

According to the question, the total profit from the Spanish club fundraiser varies directly with the number of dinner tickets sold.

If the sale of 14 tickets results in a profit of : $175.

Therefore, Profit in 1 ticket = 175/14 = 12.5 dollars

Let us assume 'x' tickets are sold in order to reach the fund-raising goal of $600.

[tex]\begin{gathered} L^{\prime}\Rightarrow(7,2) \\ M^{\prime}\Rightarrow(4,1) \\ N^{\prime}\Rightarrow(4,2) \end{gathered}[/tex]

On observation, the shapes show a dilation and a shift in position.

The image has a scale factor of 1/2, meaning it is reduced by 1/2. Therefore, the original coordinates will be reduced to give:

Answers

The given sequence is

1, 1/2, 1/4, 1/8......

we can see that the ratio of the consecutive terms is the same. We have

1/2/1 = (1/4)/(1/2) = (1/8)/(1/4) = 1/2

This means that it is a geometric sequence

To find the amount of the substance left after 21 half lifes, we would find the 21st term of the sequence. The formula for finding the nth term of a geometric sequence is

an = a1r^(n - 1)

a1 = 1

n = 21

r = 0.5

Thus,

a21 = 1 * 0.5^(21 - 1) = 0.5^20

a21 = 0.00000095367
