The equation in vertex form is y = 2(x+3)² + 1. The vertex is (-3,1), the axis of symmetry is x = -3, and the direction of opening is upwards.
The vertex form of the equation is y = a(x-h)^2 + k, where (h, k) is the vertex. The axis of symmetry is x = h, and the direction of opening is determined by the value of a.
Using this formula, let us write each equation in vertex form and then identify the vertex, axis of symmetry, and direction of opening.
1. y = x² + 8x + 18
To write this equation in vertex form, we need to complete the square. y = x² + 8x + 18 is equivalent to y = (x+4)² - 2. Therefore, the equation in vertex form is y = (x+4)² - 2.
The vertex is (-4,-2), the axis of symmetry is x = -4, and the direction of opening is upwards.2
. y = -x² - 12x - 36To write this equation in vertex form, we need to complete the square. y = -x² - 12x - 36 is equivalent to y = -(x+6)² - 12. Therefore, the equation in vertex form is y = -(x+6)² - 12.
The vertex is (-6,-12), the axis of symmetry is x = -6, and the direction of opening is downwards.3. y = 2x² + 12x + 13To write this equation in vertex form, we need to complete the square. y = 2x² + 12x + 13 is equivalent to y = 2(x+3)² + 1.

which of the following statements is true? question 4 options: the population mean and a sample mean for a sample selected from the population will usually be different values. the mean of the population will generally be larger than the mean of the sample selected from that population. the population mean and sample mean will always be identical. the mean of a population will always be larger than the population standard deviation.
The statement that is true among the given options is: "The population mean and a sample mean for a sample selected from the population will usually be different values." This statement accurately describes the relationship between the population mean and a sample mean.
In statistics, the population mean refers to the average value of a variable in the entire population, while a sample mean represents the average value of the variable calculated from a subset of the population (a sample). It is important to note that unless the sample is the entire population itself, the sample mean will typically differ from the population mean.
The reason for this discrepancy is due to sampling variability. When we select a sample from a population, we are observing a smaller subset of the whole, which introduces some level of randomness or uncertainty. Different samples from the same population may yield slightly different values for the sample mean.
However, as the sample size increases, the sample mean tends to converge towards the population mean.
In summary, the population mean and sample mean are generally not identical, and their values are likely to differ due to sampling variability. The sample mean provides an estimate of the population mean, and the accuracy of this estimate improves with larger sample sizes.

Find the first 4 terms, a10, Jamini an n≥3 n-2' and a₁5 of the sequence with the following nth term.
The sequence with the given nth term is n-2. The first four terms of the sequence are a₁ = -1, a₂ = 0, a₃ = 1, and a₄ = 2. The term a₁₀ is equal to 8, a₉ is equal to 7, and a₁₅ is equal to 13.
The given nth term of the sequence is n-2, which means that each term is obtained by subtracting 2 from the corresponding value of n.
To find the first four terms of the sequence, we substitute the values of n from 1 to 4 into the nth term expression. Thus, we have a₁ = 1-2 = -1, a₂ = 2-2 = 0, a₃ = 3-2 = 1, and a₄ = 4-2 = 2.
To find a specific term, we substitute the corresponding value of n into the nth term expression. For example, a₁₀ = 10-2 = 8, a₉ = 9-2 = 7, and a₁₅ = 15-2 = 13.
In summary, the first four terms of the sequence are a₁ = -1, a₂ = 0, a₃ = 1, and a₄ = 2. The term a₁₀ is equal to 8, a₉ is equal to 7, and a₁₅ is equal to 13.

Here we have two quadratics, these are:
f(x) = ax² + bx + c
g(x) = kx² + jx + n
Notice that in the graph of (f + g)(x), we have a line instead of a quadratic, so the quadratic term is zero, this means that:

find the coordinates of point P along the directed line segment ST so that SP to PT is the given ratio. 1. S(6,4), T(-4, -8); 1 to 3 2. S(-6, 7), 7(9,25); 2 to 3
First, we find the length of ST and multiply it by the given ratio to get the length of SP. Then, we use the midpoint formula to find the coordinates of point P.1. S(6,4), T(-4, -8); 1 to 3
Let P be the point on the directed line segment ST such that SP : PT = 1 : 3. We need to find the coordinates of P.Step 1: Find the length of ST.
Let S(x1, y1) and T(x2, y2) be the coordinates of S and T respectively. Then we can use the distance formula to find the length of ST.
d(ST) = √[(x2 - x1)² + (y2 - y1)²]
d(ST) = √[(-4 - 6)² + (-8 - 4)²]
d(ST) = √(100 + 144)
d(ST) = √244d(ST) = 2√61
Find the length of SP.We know that
SP : PT = 1 : 3. Therefore,
SP = (1/4)ST.SP = (1/4)(2√61)SP = (1/2)√61
Use the midpoint formula to find the coordinates of P.Let (x, y) be the coordinates of P. Then we can use the midpoint formula to find
(x, y).x = (1/4)(2x2 + 2x1) = (1/4)(2(-4) + 2(6)) = 1y = (1/4)(2y2 + 2y1) = (1/4)(2(-8) + 2(4)) = -1
The coordinates of P are (1, -1).
Once we have the length of SP, we can use the midpoint formula to find the coordinates of P. In the first example, we found that the coordinates of P are (1, -1) if SP : PT = 1 : 3. In the second example, we will use the same method to find the coordinates of P when S(-6, 7) and T(9, 25) are the given points, and
SP : PT = 2 : 3.
We will also find the length of ST, the length of SP, and the coordinates of P.2. S(-6, 7), T(9, 25); 2 to 3Let P be the point on the directed line segment ST such that SP : PT = 2 : 3. We need to find the coordinates of P.Step 1: Find the length of ST.Let S(x1, y1) and T(x2, y2) be the coordinates of S and T respectively. Then we can use the distance formula to find the length of ST.
d(ST) = √[(x2 - x1)² + (y2 - y1)²]
d(ST) = √[(9 - (-6))² + (25 - 7)²]
d(ST) = √(225 + 324)
d(ST) = 3√61
We know that SP : PT = 2 : 3. Therefore,
SP = (2/5)ST.SP = (2/5)(3√61)SP = (6/5)√61
Use the midpoint formula to find the coordinates of P.Let (x, y) be the coordinates of P. Then we can use the midpoint formula to find (x, y).x = (2/5)(x2 + x1) = (2/5)(9 + (-6)) = -3/5 y = (2/5)(y2 + y1) = (2/5)(25 + 7) = 16
The coordinates of P are (-3/5, 16).
To find the coordinates of point P along the directed line segment ST so that SP to PT is the given ratio, we need to find the length of ST and multiply it by the given ratio to get the length of SP. Then, we use the midpoint formula to find the coordinates of point P.

What is Unitary Method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Steps to Use Unitary Method
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Given:
price of 16 snack- size bags of chips = 7.84
Cost of 1 bag of chip = 7.84 /16
= $0.49
and, price of 24 snack-size bags of pretzels = 12.48
Cost of 1 snack-size bags of pretzels = 12.48 / 24
= 0.52
Hence, by $0.03 pretzels cost more than cost of bag of chips.

HELPPP PLEASEEE
Answer:
16. x = 40
17. y = 15
Step-by-step explanation:
16. Given that f is parallel to s, therefore by the corresponding theorem and linear pair theorem, <1 + 3x = 180°
60° + 3x = 180° (substitution)
3x = 180° - 60° (Subtraction property of equality)
3x = 120°
x = 120/3 (division property of equality)
x = 40
17. Since f and s are parallel, therefore,
m<1 = (5y - 7)° (alternate interior angles are congruent)
68° = 5y - 7 (substitution)
68 + 7 = 5y (addition property of equality)
75 = 5y
75/5 = y (division property of equality)
15 = y

Plaza Corporation purchased 70 percent of Square Company's voting common stock on January 1, 20X5, for $291,200. On that date, the noncontrolling interest had a fair value of $124,800 and the book value of Square's net assets was $380,000. The book values and fair values of Square's assets and liabilities were equal except for land that had a fair value $14,000 higher than book value. The amount attributed to goodwill as a result of the acquisition is not amortized and
In a purchase acquisition, the purchase price is allocated to the fair value of the net assets acquired. In this case, Plaza Corporation has purchased 70% of Square Company's voting common stock.
Since the noncontrolling interest in Square is 30% and has a fair value of $124,800, the implied fair value of Square Company is $178,285 ($291,200 - $124,800).The difference between the purchase price and the fair value of net assets acquired represents goodwill. The fair value of net assets acquired is $380,000 + $14,000 = $394,000. Therefore, the goodwill is $116,485 ($178,285 - $394,000).The goodwill is not amortized but is subject to impairment testing at least annually. The goodwill impairment test compares the fair value of the reporting unit, in this case, Square Company, to the carrying amount of the reporting unit, including the goodwill. If the fair value of the reporting unit is less than its carrying amount, an impairment loss is recognized, which reduces the carrying amount of the goodwill.
Based on the provided information, the amount attributed to goodwill as a result of the acquisition is $116,485. It is not amortized but is subject to impairment testing at least annually.
