Step-by-step explanation:
You want the vertex-form equation of the parabola with vertex (-3, -1) and opening downward.
Vertex formFor vertex (h, k), the vertex form equation of a parabola is ...
y = a(x -h)² +k
Given that (h, k) = (-3, -1), the equation will have the form ...
y = a(x -(-3))² + (-1)
y = a(x +3)² -1 . . . . . . . . . . matches choice C
The value of 'a' will be negative when the parabola opens downward. Here, its value is -1.
y = -(x +3)² -1

Two coins are tossed. What is the probability of both coins landing on heads?
Answers
The probability of both coins landing on heads when two coins are tossed is 1/4, or 0.25, or 25%.
When two coins are tossed, there are four possible outcomes: both coins can land on heads (HH), both coins can land on tails (TT), the first coin can land on heads and the second coin on tails (HT), or the first coin can land on tails and the second coin on heads (TH).
Since we are interested in the probability of both coins landing on heads, we need to determine the number of favorable outcomes (HH) out of the total number of possible outcomes.
Out of the four possible outcomes, only one outcome is favorable (HH). Therefore, the probability of both coins landing on heads is 1 out of 4.
In fraction form, this can be written as 1/4. The probability can also be expressed as a decimal, which is 0.25, or as a percentage, which is 25%.
It's important to note that in this case, we assume that the coins are fair and unbiased, meaning that the probability of landing on heads is equal to the probability of landing on tails, which is 1/2 or 0.5 for each coin individually.

Answers
Probability that a blue marble is chosen and then a black marble is 1/6 .

Neighbor Jim will give her a board that he says is 8 and 1/2 feet long. Neighbor Malia will give her two boards that she says are each 126 inches long. What is the total combined length of lumber Jenna has received?
Answers
The Jenna has entered a total concerted length of timber that measures 354inches.
To calculate the total concerted length of timber Jenna has entered, we need to convert all the measures to a harmonious unit.
Let's convert the measures to elevation for easier computation. Neighbor Jim's board is 8 and1/2 bases long, which is equal to8.5 bases. Since there are 12 elevation in a bottom, the length of Jim's board in elevation is8.5 * 12 = 102 elevation.
Neighbor Malia has two boards, each measuring 126 elevation. Now we can add up the lengths of all the boards to find the total concerted length.
Total combined length = Jim's board length Malia's board length Malia's board length = 102 elevation 126 elevation 126 elevation = 354 elevation.

a) Share £5 in the ratio 2 : 3
b) Share £50 in the ratio 2:3
c) Share £500 in the ratio 2 : 3
Answers
Total ratio parts = 2 + 3 = 5
Share for the first part (2/5 of £5):
(2/5) * £5 = £2
Share for the second part (3/5 of £5):
(3/5) * £5 = £3
Therefore, in the ratio 2:3, £2 would be allocated to the first part, and £3 would be allocated to the second part.
b) To share £50 in the ratio 2:3, we follow a similar process:
Total ratio parts = 2 + 3 = 5
Share for the first part (2/5 of £50):
(2/5) * £50 = £20
Share for the second part (3/5 of £50):
(3/5) * £50 = £30
Thus, in the ratio 2:3, £20 would be allocated to the first part, and £30 would be allocated to the second part.
c) Sharing £500 in the ratio 2:3:
Total ratio parts = 2 + 3 = 5
Share for the first part (2/5 of £500):
(2/5) * £500 = £200
Share for the second part (3/5 of £500):
(3/5) * £500 = £300
Hence, in the ratio 2:3, £200 would be allocated to the first part, and £300 would be allocated to the second part.
Each part will be worth £5/5 = £1.
To find the share of each ratio, we need to multiply their respective parts by this value:
- Share of the first ratio (2 parts): 2 x £1 = £2
- Share of the second ratio (3 parts): 3 x £1 = £3
Therefore, the shares are £2 and £3.
b) To share £50 in the ratio 2:3, we need to divide it into 2 + 3 = 5 parts.
Each part will be worth £50/5 = £10.
To find the share of each ratio, we need to multiply their respective parts by this value:
- Share of the first ratio (2 parts): 2 x £10 = £20
- Share of the second ratio (3 parts): 3 x £10 = £30
Therefore, the shares are £20 and £30.
c) To share £500 in the ratio 2:3, we need to divide it into 2 + 3 = 5 parts.
Each part will be worth £500/5 = £100.
To find the share of each ratio, we need to multiply their respective parts by this value:
- Share of the first ratio (2 parts): 2 x £100 = £200
- Share of the second ratio (3 parts): 3 x £100 = £300
Therefore, the shares are £200 and £300.

Answers
In interval notation, this can be written as (0, 6), which corresponds to option A.
To determine over which interval of the domain the function is negative, we need to examine the behavior of the linear function between the x-axis intercept and the y-axis intercept.
Given that the linear function intersects the y-axis at (0, 4) and the x-axis at (6, 0), we can calculate the slope of the line using the formula:Slope = (change in y) / (change in x) = (0 - 4) / (6 - 0) = -4 / 6 = -2/3
Since the slope of the line is negative, we know that the function is decreasing as x increases. Therefore, the function is negative over the interval of the domain where x is greater than 0 and less than 6, excluding the endpoints.O

3. A website is offering a promotion, during which customers can buy up to 100 photos for a flat fee. The
cost per photo varies inversely with the number of photos a customer buys, as shown in the table below.
What function models the data?
Answers
To determine the function that models the data, we need to analyze the relationship between the cost per photo and the number of photos a customer buys. From the given information, we can observe that the cost per photo varies inversely with the number of photos. This implies that as the number of photos increases, the cost per photo decreases, and vice versa.
To model this relationship, we can use the inverse variation equation, which can be expressed as:
y = k/x
Here, y represents the cost per photo, x represents the number of photos, and k is the constant of variation.
Let's examine the data given in the table to find the value of k:
Number of Photos (x) Cost per Photo (y)
10 10
25 4
50 2
100 1
We can see that as the number of photos increases, the cost per photo decreases. We can use any pair of values from the table to solve for k. Let's choose the pair (50, 2):
2 = k/50
Solving for k:
k = 2 * 50 = 100
Now that we have the value of k, we can write the function that models the data:
y = 100/x
Therefore, the function that models the data is y = 100/x, where y represents the cost per photo and x represents the number of photos a customer buys.

In this case, we know that the volume is[tex] 972\pi[/tex] cubic inches.
Substituting this into the formula, we get:
[tex]972\pi = \frac{4}{3} \pi r^3[/tex]
Dividing both sides by π, we get:
[tex]972 = \frac{4}{3} r^3[/tex]
Multiplying both sides by [tex]\frac{3}{4}[/tex], we get:

Taking the cube root of both sides, we get:
r = 9
Therefore, the radius of the sphere is 9 inches.
x = 12 log 8x ( Find the value of x.?
Answers
The value of x that satisfies the equation x = 12 log₆ (8x) is x = 0.
We have,
To find the value of x in equation x = 12 log₆ (8x), we can solve it algebraically.
Here's how:
Start by isolating the logarithm term by dividing both sides of the equation by 12:
x/12 = log₆ (8x)
Now, rewrite the logarithmic equation in exponential form:
6^(x/12) = 8x
Apply the properties of exponents to simplify the equation further:
(2^3)^(x/12) = (2^3)^x
2^(3x/12) = 2^(3x)
Since the bases are equal, we can equate the exponents:
3x/12 = 3x
Next, cross-multiply to get rid of the fraction:
3x = 12 * 3x
Simplify:
3x = 36x
Subtract 36x from both sides:
3x - 36x = 0
Simplify:
-33x = 0
Divide both sides by -33:
x = 0
Therefore,
The value of x that satisfies the equation x = 12 log₆ (8x) is x = 0.

Within a week Nepali rupee is devaluated by 5%.He again exchanged his dollars to Nepali rupee after a week. a) How many dollars did he get with Rs 540000? b) What is the new exchange rate after devaluation in Nepali rupee? c) How much did he gain or lose? d) After devaluation of Nepali rupee, if the bank took 2% commission, how many rupee would he gain or lose?
Answers
Answer: a) To find out how many dollars Mr Anil got with Rs 540,000, we'll divide the amount in Nepali rupees by the exchange rate.
Exchange rate: 1$ = Rs 120Amount in Nepali rupees: Rs 540,000Number of dollars = Amount in Nepali rupees / Exchange rateNumber of dollars = 540,000 / 120Number of dollars = 4,500Therefore, Mr Anil got 4,500 dollars with Rs 540,000.
b) After the devaluation of the Nepali rupee by 5%, the new exchange rate would be 5% less than the previous rate.
New exchange rate = Previous exchange rate - (Previous exchange rate * 5%)
New exchange rate = 120 - (120 * 0.05)New exchange rate = 120 - 6New exchange rate = 114The new exchange rate after the devaluation is 1$ = Rs 114.
c) To calculate how much Mr Anil gained or lost, we need to compare the initial exchange rate with the new exchange rate.
Initial exchange rate: 1$ = Rs 120New exchange rate: 1$ = Rs 114Gained or lost = Number of dollars * (New exchange rate - Initial exchange rate)
Gained or lost = 4,500 * (114 - 120)Gained or lost = 4,500 * (-6)Gained or lost = -27,000Mr Anil lost 27,000 rupees due to the devaluation of the Nepali rupee.
d) If the bank took a 2% commission on the transaction, we need to calculate the commission amount and adjust the gain or loss accordingly.
Commission amount = Number of dollars * (Commission rate)Commission amount = 4,500 * (0.02)Commission amount = 90Adjusted gain or loss = Gained or lost - Commission amountAdjusted gain or loss = -27,000 - 90Adjusted gain or loss = -27,090
After the devaluation of the Nepali rupee and considering the 2% commission, Mr Anil would lose 27,090 rupees.

In slope intercept form, the line's equation is y = 2x + 1. We must apply the formula y = mx + b to formulate an equation in slope intercept form. The slope of the line is represented by m, while the y-intercept is represented by b.
We need two locations on the line to find the slope. Assume we have points (2,5) and (4,9). We may calculate the slope using the following formula:
m = (9 - 5) / (4 - 2) m = (9 - 5) / (4 - 2)
m = 2
As a result, the slope of the line is 2.
We must now identify the y-intercept, which is the point at where the line crosses the y-axis.
We can utilise one of the points we already have to discover this. Let's start with (2,5).
y = mx + b
5 = 2(2) + b
5 = 4 + b
b = 1
As a result, the y-intercept is 1.
Now we can enter the numbers we discovered for m and b into the formula:
y = mx + b
y = 2x + 1
As a result, the slope intercept form equation of the line is y = 2x + 1.

In ΔVWX, w = 680 cm, ∠X=80° and ∠V=32°. Find the area of ΔVWX, to the nearest 10th of a square centimeter.
Answers
Area = (1/2) * base * height
In this case, we have two sides and the included angle, so we can use the formula:
Area = (1/2) * VW * WX * sin(V)
First, let's calculate the lengths of sides VW and WX using the law of sines:
VW / sin(X) = WX / sin(V)
VW / sin(80°) = WX / sin(32°)
VW = (WX * sin(80°)) / sin(32°)
Now, substitute the value of VW in the area formula:
Area = (1/2) * [(WX * sin(80°)) / sin(32°)] * WX * sin(V)
Area = (1/2) * WX^2 * (sin(80°) * sin(V)) / sin(32°)
Area = (1/2) * WX^2 * (sin(80°) * sin(32°)) / sin(32°)
Area ≈ (1/2) * WX^2 * 0.7365 (rounded to four decimal places)
Now, substitute the value of WX and calculate the area:
Area ≈ (1/2) * (680 cm)^2 * 0.7365
Area ≈ 139,850.4 cm^2
Therefore, the area of triangle VWX is approximately 139,850.4 square centimeters to the nearest 10th of a square centimeter.
