Answer:

To write the equation of the parabola in vertex form, we use the standard form:

y = a(x - h)^2 + k, where (h, k) is the vertex.

Given that the vertex is (-4, -6), we have:

h = -4 and k = -6

Now, we need to find the value of "a" using the point (-14, 13/2) which lies on the parabola.

Substituting the values in the standard form, we get:

13/2 = a(-14 - (-4))^2 - 6

Simplifying, we get:

13/2 = 100a - 6

100a = 13/2 + 6

a = 19/200

Therefore, the equation of the parabola in vertex form is:

y = (19/200)(x + 4)^2 - 6

In the exponential decay, A) r = -0.0839 , B) r = -8.39% , C) Value=$11,800.

What is exponential decay?

The term "exponential decay" in mathematics refers to the process of a constant percentage rate reduction in an amount over time. It can be written as y=a(1-b)x, where x is the amount of time that has passed, an is the initial amount, b is the decay factor, and y is the final amount.

To find the annual rate of change between 1992 and 2006, we can use the formula:

r = [tex](V_2/V_1)^{1/n}-1[/tex]

where V1 is the initial value, V2 is the final value, and n is the number of years between the two values.

=>r = -0.0839

Therefore, the rate of change between 1992 and 2006 is -0.0839.

To express the rate of change in percentage form, we can multiply the result from part A by 100:

=>r = -0.0839 x 100

=> r = -8.39%

Therefore, the rate of change between 1992 and 2006 is a decrease of 8.39%.

To find the value of the car in the year 2009, we can assume that the value continues to drop at the same percentage rate as calculated in part A.

From 2006 to 2009, there are 3 years. So, using the formula for exponential decay, we have:

where V0 is the value in 2006, r is the rate of decrease, and n is the number of years between 2006 and 2009.

=>V = 11792.51

Therefore, the value of the car in the year 2009 would be approximately $11,800 (rounded to the nearest $50).

Answer: -3x - 6y = -27 (Equation 1)

4x - 2y = -4 (Equation 2)

We can use the method of elimination, which involves adding or subtracting the equations to eliminate one of the variables.

In this case, we can start by multiplying Equation 2 by 3 to eliminate the y variable:

-3x - 6y = -27 (Equation 1)

12x - 6y = -12 (Equation 2 multiplied by 3)

Now we can add Equation 1 to Equation 2:

-3x - 6y = -27 (Equation 1)

12x - 6y = -12 (Equation 2 multiplied by 3)

9x = -39

Simplifying this expression, we get:

x = -39/9 = -13/3

Now we can substitute this value of x into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:

-3x - 6y = -27

-3(-13/3) - 6y = -27

13 + 6y = -27

6y = -40

y = -40/6 = -20/3

Therefore, the solution to the system of equations is x = -13/3 and y = -20/3, or (-13/3, -20/3) in coordinate form.

To check the solution, we can substitute the values of x and y into both equations:

-3(-13/3) - 6(-20/3) = -27

4(-13/3) - 2(-20/3) = -4

Simplifying both expressions, we get:

13 + 40 = 27 (which is true)

-52/3 + 40/3 = -4 (which is also true)

Therefore, the solution is correct.

Answer: 6 songs.

Step-by-step explanation:

Each song is $2 dollars. $12 divided by $2 equals 6.

So he can download 6 songs.

Given the above circles,

1) x = 42°

2) x = 29°

3) x = 101°

4) x = 37°

5) x = 31°

6) x = 120°

1) x = 42° because the Angles at the circumference of a circle

subtended by the same arc are equal. Since 35° and 103° are two of the three angles in a triangle whose third angle subtends the circumference of the circle along with ∠x, and the third angle = 180 - 35 - 103 = 42° therefore,  x = 42°

2) x = 29° because according to the central angle theorem, the angle at the circumference is double the one at the center. Since the angle at the circumference is 61°, the one at the center is 122°. Since the line from the center that couches on both sides of the circumference is the radius, they are equal. Hence, the angles formed at their bases are equal.

Thus, x = (180-122)/2

x = 29°

3) 3) x = 101° because the opposite angles of a cyclic quadrilateral are supplementary.

4) x = 37° based on the angle in the alternate segment theorem.

5) x= 31° is based on the "inscribed angle theorem" or the "theorem of the intercepted arc".

This theorem states that if an angle is inscribed in a semicircle, then the angle is a right angle (i.e., it measures 90 degrees). In other words, if you draw any two chords from the ends of the diameter to any point on the arc of the semicircle, then the angle formed by these two chords at the point on the arc will always be 90 degrees.

6) x = 120° on the basis of  the "Tangent-Secant Angle Theorem" or "Tangent-Chord Angle Theorem".

In the problem given above, the angle x is formed by two tangents intersecting at the vertex outside the circle, and the Tangent-Secant (or Tangent-Chord) Angle Theorem is used to find its measure.

The arc formed at the points where the two tangents meet is twice the angle formed inside the circle which is = 30°
Thus, where the rest of the arc traced from the upper point of tangency  is traced back to the lower point of tangency is called A,

The measure of arc A is 360° - 60° = 300°.

The measure of angle x is half the difference between the measures of the intercepted arcs, which is (300° - 60°)/2 = 120°.

Therefore, the measure of angle x would be 120°.

Answer:

The formula for the surface area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

where l, w, and h are the length, width, and height of the prism, respectively.

Since the length, width, and height of the prism in this case are all x inches, we can substitute x for l, w, and h in the formula to get:

Surface Area = 2(x)(x) + 2(x)(x) + 2(x)(x)

Simplifying the equation, we get:

Surface Area = 2x^2 + 2x^2 + 2x^2

Surface Area = 6x^2

Therefore, the equation for the surface area of a prism with a length, width, and height of x inches is:

Surface Area = 6x^2 square inches

Answer:

To work out the probability that Caroline buys fruit or buys a CD or both, you can use the formula:

P(A or B) = P(A) + P(B) - P(A and B)

where A and B are events.

In this case, A is the event that Caroline buys fruit and B is the event that Caroline buys a CD.

The probability that Caroline buys fruit is 0.4 and the probability that Caroline buys a CD is 0.6.

To find the probability that Caroline buys fruit and a CD, you can multiply the probabilities of the two events:

P(A and B) = P(A) x P(B) = 0.4 x 0.6 = 0.24

Therefore, the probability that Caroline buys fruit or buys a CD or both is:

P(A or B) = P(A) + P(B) - P(A and B) = 0.4 + 0.6 - 0.24 = 0.76

So, the probability that Caroline buys fruit or buys a CD or both is 0.76 .

Answer: Kayla sold 1/12 gallons more than Ethan.

Step-by-step explanation:

Let's start by finding out how much lemonade Kayla sold. We know that together, Ethan and Kayla sold 1 1/4 gallons, which is the same as 5/4 gallons. We also know that Ethan sold 2/3 gallons. Therefore, we can find how much Kayla sold by subtracting Ethan's sales from the total sales:

Kayla's sales = Total sales - Ethan's sales

Kayla's sales = 5/4 - 2/3

To subtract these fractions, we need to find a common denominator. The smallest common multiple of 4 and 3 is 12, so we can rewrite the fractions with 12 as the denominator:

Kayla's sales = (5/4)(3/3) - (2/3)(4/4)

Kayla's sales = 15/12 - 8/12

Kayla's sales = 7/12

Therefore, Kayla sold 7/12 gallons of lemonade. Now, we need to compare this to Ethan's sales. We can convert Ethan's sales to twelfths to make it easier to compare:

Ethan's sales = (2/3)(4/4) = 8/12

Now we can see that Kayla sold more lemonade than Ethan. The difference in sales is:

Kayla's sales - Ethan's sales = 7/12 - 8/12

Kayla's sales - Ethan's sales = -1/12

The result is negative, which means that Ethan sold 1/12 gallons less than Kayla. Therefore, Kayla sold 1/12 gallons more than Ethan.

= cos(2α)(2cos(5π/16)cos(3π/16)) - sin(2α)(2cos(7π/16)sin(π/16)) (using the sum-to-product formula again)

= 2cos(2α)cos(5π/16)cos(3π/16) - 2sin(2α)cos(7π/16)sin(π/16)

= 2cos(2α)(cos(5π/16)cos(3π/16) - sin(5π/16)sin(3π/16)) (using the product-to-sum formula)
