Write the equation for the function described, in STANDARD FORM.

STANDARD FORM is [tex]3x^2 + 24x + 32y + 192 = 0[/tex] ,parabola has a maximum point at its vertex, which is (2, -3).
what is equation of parabola in standard form:to write the equation for the given parabola in standard form, we need to use the vertex form of the equation of a parabola, which is:
[tex]y = a(x - h)^2 + k[/tex]
where (h, k) is the vertex of the parabola and 'a' is the coefficient that determines the shape and direction of the parabola.
We know that the x-intercepts of the parabola are -2 and 6. This means that the parabola intersects the x-axis at these two points. Therefore, the roots of the quadratic equation are -2 and 6.
We also know that the y-intercept of the parabola is -48, which means that the point (0, -48) lies on the parabola.
Since the parabola is symmetric about the vertical line passing through its vertex, the x-coordinate of the vertex is the midpoint of the x-intercepts, which is (6 - 2)/2 = 2.
Therefore, the vertex of the parabola is (2, k), where k is the y-coordinate of the vertex.
Now we can use the vertex form
[tex]y = a(x - 2)^2 + k[/tex]
We need to determine the values of 'a' and 'k' to complete the equation.
Since the parabola passes through the point (0, -48), we can substitute x = 0 and y = -48 into the equation:
[tex]-48 = a(0 - 2)^2 + k[/tex]
-48 = 4a + k
Similarly, since the x-intercepts are -2 and 6, we can substitute x = -2 and x = 6 into the equation to get:
[tex]0 = a(-2 - 2)^2 + k[/tex]
0 = 16a + k
0 = a(6 - 2)^2 + k
0 = 16a + k
Solving these three equations for 'a' and 'k', we get:
a = -3/8 and k = -3
Substituting these values into the vertex form equation, we get:
[tex]y = (-3/8)(x - 2)^2 - 3[/tex]
Therefore, the equation for the parabola in standard form is:
[tex]3x^2 + 24x + 32y + 192 = 0[/tex]
This parabola has a maximum point at its vertex, which is (2, -3).

Lee’s family had a garden in the shape of a right triangle. The total area of the garden is 16 square feet. If they expand the garden to form a triangle with twice the base and twice the height, by how much will they increase the size of their garden?
you say 48 is the answer but there is no step by step instruction shown. Please peovide step by step instruction
According to the question we can conclude that expanding the garden will increase its area by 48 square feet.
Let's call the base of the original right triangle "b" and the height "h". The area of the right triangle is given by the formula:
Area = (1/2) * base * height
So we have:
16 = (1/2) * b * h
When we factor in a single of the variables, then obtain:
b * h = 32
Now, the new triangle will have twice the base and twice the height of the original triangle, so the new base will be 2b and the new height will be 2h. The area of the new triangle is given by the formula:
(Half) * Additional Base * Increased Height = New Area
Plugging in the new values, we get:
New area = (1/2) * 2b * 2h
Simplifying:
New area = 2bh
Now we need to find by how much the area has increased, which is the difference between the new area and the old area:
Area increase = Current area minus Old area.
Area increase = 2bh - 16
Substituting bh = 32, we get:
Area increase = 2(32) - 16
Area increase = 48
Therefore, expanding the garden will increase its area by 48 square feet.

What is arc mBC?
Inscribed angles
Answer:
[tex]\textsf{B.} \quad m\overset{\frown}{BC}=56^{\circ}[/tex]
Step-by-step explanation:
To find the measure of arc BC, first calculate the measures of arc ABC and arc BCD.
Definitions:
A chord is a straight line joining two points on the circle.An inscribed angle is the angle formed (vertex) when two chords meet at one point on a circle.An intercepted arc is the arc that is between the endpoints of the chords that form the inscribed angle.Inscribed Angle TheoremThe measure of an inscribed angle is half the measure of the intercepted arc.
Therefore, we can use the inscribed angle theorem to calculate the measures of arcs ABC and BCD:
[tex]\boxed{\begin{aligned}\angle ADC&=\dfrac{1}{2} \overset{\frown}{ABC}\\\\\implies 70^{\circ}&=\dfrac{1}{2} \overset{\frown}{ABC}\\\\ \implies \overset{\frown}{ABC}&=140^{\circ}\end{aligned}}[/tex] [tex]\boxed{ \begin{aligned}\angle BAD&=\dfrac{1}{2} \overset{\frown}{BCD}\\\\\implies 98^{\circ}&=\dfrac{1}{2} \overset{\frown}{BCD}\\\\ \implies \overset{\frown}{BCD}&=196^{\circ}\end{aligned}}[/tex]
The sum of the arcs is 360°. Therefore:
[tex]\overset{\frown}{ABC}+\overset{\frown}{CD}+\overset{\frown}{AD}=360^{\circ}[/tex]
Substitute the given measure of arc AD and the found measure of arc ABC and solve for arc CD:
[tex]\implies 140^{\circ}+\overset{\frown}{CD}+80^{\circ}=360^{\circ}[/tex]
[tex]\implies \overset{\frown}{CD}=140^{\circ}[/tex]
The measure of arc BCD is the sum of arcs BC and CD. Therefore:
[tex]\overset{\frown}{BC}+\overset{\frown}{CD}=\overset{\frown}{BCD}[/tex]
To find the measure of arc BC, substitute the found measures of arc CD and arc BCD and solve for BC:
[tex]\implies \overset{\frown}{BC}+140^{\circ}=196^{\circ}[/tex]
[tex]\implies \overset{\frown}{BC}=56^{\circ}[/tex]
Therefore, the measure of arc BC is 56°.

A. The graphed line will not change, because additional consumers
were not added to limit population growth.
B. The graphed line will eventually level off because the ecosystem
lacks a way to recycle matter.
C. The graphed line will eventually level off because the ecosystem lacks a way to recycle matter.
D. The graphed line will increase and then level off again as the population reaches a new carrying capacity.
Answer:
B. The graphed line will eventually level off because the ecosystem
lacks a way to recycle matter.
Step-by-step explanation:
Based on the information I can get from the question, option B is likely the correct answer. The graphed line will eventually level off because there is no way for dead organisms to be recycled back into the ecosystem and no additional nutrients being added. This means that the bacteria will consume all available resources and will not be able to sustain further growth, resulting in the population reaching its carrying capacity. Option A is not relevant to the growth of the bacteria population, and option D is incorrect as there are no additional nutrients being added, indicating that a new carrying capacity is not expected. Therefore, option B is the correct choice.
500g packet of beans cost £1.55
Answer: The packet is better value for money is a 125 g packet of beans which costs £0.36.
Step-by-step explanation:
The better value for money of a packet of beans can be calculated as follows?
The first step we can check on the first packet value for money by calculating the costs of 1 g of beans as follows :
(1/500) x £1.55 = £0,003
In the second step we can check on the second packet value for money by calculating the costs of 1 g of beans as follows :
(1/125) x £0.36 = £0,0028.
Hence, the better value for money between those two packets of beans is the second packet of beans which is given 125 g and costs £0.36

Now, we need to round Point A to the nearest whole number and the nearest ten.
To round to the nearest whole number:
1. Observe the position of Point A on the number line.
2. Since Point A is slightly above 35, it's closer to 35 than 36.
3. Therefore, Point A rounded to the nearest whole number is 35.
To round to the nearest ten:
1. Observe the position of Point A (35) in relation to the tens (30 and 40) on the number line.
2. Since 35 is exactly halfway between 30 and 40, it is equidistant from both.
3. In this case, we round up to the next ten, which is 40.

3. Julianna deposits $2,340 in a bank paying an
annual interest rate of 3.1% compounded
continuously. Find the balance after 3 years
Therefore, the balance after 3 years of continuous compounding at an annual interest rate of 3.1% is approximately $2,701.85.
What is percent?Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred," so when we say something is, for example, 25%, we mean it is 25 out of 100, or 0.25 as a decimal. Percentages are often used to express ratios or proportions, such as in statistics, finance, and everyday life. Some common examples include: Interest rates: A bank might advertise a 5% annual interest rate on a savings account, which means that the account balance will increase by 5% (or 0.05) each year. Discounts: A store might offer a 20% discount on a product, which means that the price will be reduced by 20% (or 0.20) of the original price. Grades: A student might receive a grade of 85% on a test, which means that they answered 85 out of 100 questions correctly. Percentages can be converted to decimals or fractions, and vice versa, using simple arithmetic operations. For example, to convert a percentage to a decimal, divide by 100. To convert a decimal to a percentage, multiply by 100 and add a percent sign (%).
Here,
The formula for continuous compounding is:
[tex]A = Pe^{rt}[/tex]
where A is the ending balance, P is the principal amount, r is the annual interest rate (as a decimal), t is the time in years, and e is the mathematical constant approximately equal to 2.71828.
Plugging in the given values, we get:
A = 2340 * [tex]e^{0.031*3}[/tex]
Simplifying the exponent, we get:
A = 2340 * [tex]e^{0.093}[/tex]
Using a calculator, we get:
A ≈ $2,701.85

A bag holds 13 marbles. 6 are blue, 2 are green, and 5 are red.
Answer:
[tex]\boxed{\frac{8}{13} }[/tex]
Step-by-step explanation:
Probability is found by dividing the number of favorable outcomes by the total number of outcomes.
[tex]\text{P}=\dfrac{\text{favorable outcomes}}{\text{total outcomes}}[/tex]
For this problem, the favorable outcome is selecting a blue or green marble. There are 8 outcomes for this because there are 6 outcomes for blue and 2 fr green.
The total outcomes are all the marbles. Each marble could be an outcome, so there are 13 outcomes (1 for each marble).
[tex]\text{P}=(\text{blue or green})=\dfrac{8}{13}[/tex]
This fraction cannot be reduced, so the probability of selecting a blue or green marble is 8/13.

the companies bounce zone and jump world run many trampoline parks around the country. the box plots show the number of trampolines at their park. which conclusion is best supported by the box plots?
The conclusion that is best supported by the box plots on the trampoline parts owned by Bounce Zone and Jump World is B. For both companies, about 25% of the parks have 21 or fewer trampolines.
What does the box plot show ?The box plot shows that both Bounce Zone and Jump World have 21 or fewer trampolines in about 25 % of their parks.
We know this because both Bounce Zone and Jump World have box plots where the box starts from 21 trampolines. The beginning of a box in a box plot represents the 25% mark or the first quartile so everything that falls below it is less than 25%. Bounce Zone and Jump World therefore have 21 or less trampolines in 25% of their parks.

The tank is shaped like a cylinder that is 3 ft long with a diameter of 1.8 ft. Suppose oil is drained at a rate of 1.7 ft³ per minute. If the tank starts completely full, how many minutes will it take to empty the tank? Use the value 3.14 for pi, and round your answer to the nearest minute. Do not round any intermediate computations.
Answer:
4 minutes
Step-by-step explanation:
You want to know how long it takes to drain a cylindrical tank 1.8 ft in diameter and 3 ft long at the rate of 1.7 ft³/minute. (π = 3.14)
VolumeThe volume of a cylinder can be found using the formula ...
V = (π/4)d²h . . . . . . . diameter d, height h
Then the volume of the oil tank is ...
V = 3.14/4(1.8 ft)²(3 fft) = 7.6302 ft³
TimeThe time it takes to empty the tank is found by dividing the volume by the rate:
(7.6302 ft³)/(1.7 ft³/min) ≈ 4.49 min ≈ 4 min
It will take about 4 minutes to empty the tank.

Tests show that the lives of light bulbs are
normally distributed with a mean of 750 hours
and a standard deviation of 75 hours. Find
the probability that a randomly selected light
bulb will last between 675 and 900 hours.
525 600 675 750 825 900 975
P = [?]%
Hint: use the 68 - 95 - 99.7 rule.
Enter
Answer: like three out of a thousand, would be likely to last less than 525 hours or more than 975 hours.
Step-by-step explanation:
normal distribution is shaped like a bell curve with the average (mean) at the center.
A light bulb in your problem is most likely to last about 750 hours. One standard deviation up from that would be 750 + 75, which is 825 hours, and one standard deviation down is 750 - 75, which is 675 hours.
According to the empirical rule, the interval from the average to +1 standard deviation (750 to 825) and the interval from the average to -1 standard deviation (675 to 725) each have a 34.1% probability.
From +1 to +2 standard deviations and -1 to -2 standard deviations (825 to 900 and 600 to 675) the probability is 13.5% for each interval.
From +2 to +3 standard deviations and -2 to -3 standard deviations (900 to 975 and 525 to 600) the probability is 2.1% for each interval.
These percentages are the same for any normal distribution problem. If you add up the chances you can find the probability a light bulb will last an increasing range of times centered around the average:
Within one standard deviation of the average: 68.3% (chance it will last 675 to 825 hours)
Within two standard deviations of the average: 95.4% (chance it will last 600 to 900 hours)
Within three standard deviations of the average: 99.7% (chance it will last 525 to 975 hours)
And only a very few, like three out of a thousand, would be likely to last less than 525 hours or more than 975 hours.

A javelin is being launched into the air 31 feet away from the launch site is a lamp. If the javelin is travelling vertically at 3 feet per second, what is the rate of change of the angle of elevation (θ) from the lamp to the javelin when the javelin is 37 feet off the ground?
The rate of change of the angle of elevation from the lamp to the javelin when the javelin is 37 feet off the ground is zero.
Rate of changeLet's denote the distance from the lamp to the point directly below the javelin by x, and the height of the javelin above the ground by y. Then we have two right triangles: one with legs x and y, and hypotenuse 31, and another with legs x and 37-y, and hypotenuse 37. Using the Pythagorean theorem, we can write:
x^2 + y^2 = 31^2
x^2 + (37-y)^2 = 37^2
Taking the derivative with respect to time t of both sides of each equation, we get:
2x(dx/dt) + 2y(dy/dt) = 0
2x(dx/dt) - 2(37-y)(dy/dt) = 0
Solving for (dy/dt) in terms of (dx/dt), we get:
(dy/dt) = x(dy/dx)/(-y+37)
At the given moment when the javelin is 37 feet off the ground, we have y = 37, and so:
(dy/dt) = x(dy/dx)/(-y+37) = x(dy/dx)/(-37+37) = 0
This means that the rate of change of the angle of elevation is zero at this moment. In other words, the angle of elevation is not changing at the moment when the javelin is 37 feet off the ground.

given a line DE parallel to a side AC of the triangle and intersecting the other two sides, it intersects those sides proportionally , that is
[tex]\frac{CE}{BE}[/tex] = [tex]\frac{AD}{BD}[/tex] ( substitute values )
[tex]\frac{25}{x-25}[/tex] = [tex]\frac{15}{24-15}[/tex]
[tex]\frac{25}{x-25}[/tex] = [tex]\frac{15}{9}[/tex] ( cross- multiply )
15(x - 25) = 9 × 25 = 225 ( divide both sides by 15 )
x - 25 = 15 ( add 25 to both sides )
x = 40
