Answer:

A

Step-by-step explanation:

it goes through the vertex so that means it is not moved so that rules out C and d

seeing the y value for 1 is 4 that means that it has to be A

Answer:

A

Step-by-step explanation:

by using the eqn to find for a straight line

slope = ∆y/∆x

(1,4) and (0,0) since both points are in the line

slope = 4

then,

y-y'=slope(x-x')

y-4=4(x-1)

y-4=4x-4

y=4x-4+4

y=4x

but the graph is parabolic thus

y=4x^2

this is how I did it I have no idea to do anything else so hope it works

The height of Tree A t years after being planted can be represented by the equation:

A = 30 + 2t

This equation states that the initial height of the tree (30 inches) plus the annual growth of the tree (2 inches per year) multiplied by the number of years that have passed (t) will give the current height of the tree.

The height of Tree B t years after being planted can be represented by the equation:

B = 15 + 5t

This equation states that the initial height of the tree (15 inches) plus the annual growth of the tree (5 inches per year) multiplied by the number of years that have passed (t) will give the current height of the tree.

To determine which tree is taller after 6 years, we can substitute t = 6 into each equation and compare the results:

A = 30 + 2(6) = 30 + 12 = 42 inches

B = 15 + 5(6) = 15 + 30 = 45 inches

Tree B is taller than Tree A after 6 years because 45 inches is greater than 42 inches.

The ratio of the leading coefficients and the equation of the horizontal asymptote is degree of numerator and denominator is equal.

The term coefficients in math is defined as the coefficient of the term of highest degree in a polynomial.

Here we have given that  the ratio of the leading coefficients and the equation of the horizontal asymptote.

The term horizontal asymptote is known as  a horizontal line y = b where the graph approaches the line as the inputs approach ∞ or –∞.

As we all know that if the degree of the numerator is equal to the degree of the denominator, then the horizontal asymptote is equal to the ratio of the leading coefficients.

Answer:

B

Step-by-step explanation:

We will first look at the end behavior of the graph

Is it down then up which means that the degree is 3 and the coeficcent is positive

this leaves B or C

We then know that the x intercepts are (-2,0) (1,0) (3,0)

The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!

looking at the B we have

-2³-2*-2²-5(-2)+6

this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)

You can also factor it and find the zeroes that way, but it's just more work

Since, 1 JPY = 0.0077 USD in Jan 27, 2023 08:45 UTC

Therefore, based on above information :

800 Japanese Yen 5.93 US Dollar.

The yen is the official currency of Japan. It is the third most traded currency on the foreign exchange market, after the US dollar (USD) and the euro. It is also widely used as the third key currency after the US dollar and the euro.

After World War II, the yen lost much of its pre-war value. To stabilize the Japanese economy, the yen exchange rate was fixed at 360 yen per US dollar under the Bretton Woods system. When this system was abolished in 1971, the yen was devalued and became liquid. After peaking at 271 yen per dollar in 1973, the yen appreciated to 271 yen per dollar due to the oil crisis in 1973, reaching 227 yen per dollar in 1980.

Another option is to do the calculations manually using simple mathematical formulas. However, for this you need to know the current exchange rate. As of this writing, one yen is worth $0.007.

Once you know this information, multiply the amount in JPY by the current exchange rate.

The resulting number shows how much you need to spend on your trip in US dollars.

Manual Currency Conversion Example

Suppose you have 100,000 yen and want to calculate how much money you will need to travel to the United States. Using the current exchange rate, the conversion formula would be

100,000 yen x 0.007 = $700

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Hence we get 25%

Step-by-step explanation:

Answer:

Step-by-step explanation:

You want the number of rising numbers between 2020 and 2400.

A "rising number" has digits that strictly increase from left to right.

The smallest rising number greater than 2020 is 2345. The largest rising number less than 2400 is 2389.

In this number range, the first two digits must be 23, and the remaining two digits are distinct and chosen from {4, 5, 6, 7, 8, 9}. Once a pair of digits is chosen, it can be arranged in increasing order, so the number of rising numbers is the number of ways 2 can be chosen from 6.

   C(6, 2) = 6!/(2!(6 -2)!) = 6·5/(2·1) = 15

There are 15 distinct integers between 2020 and 2400 that have their digits in increasing order.

To solve this problem, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides (called the "legs") is equal to the square of the longest side (called the "hypotenuse").

In other words, if we let $a$ and $b$ be the lengths of the two legs, and $c$ be the length of the hypotenuse, we have:

$a^2 + b^2 = c^2$

In this case, we know that the hypotenuse has length 39 units, so we can write:

$a^2 + b^2 = 39^2 = 1521$

We also know that $a$ and $b$ are both integers, since they are the lengths of sides of a triangle. We can use this information to try out different values of $a$ and see if any of them result in a value of $b$ that is also an integer.

One way to do this is to start with $a=1$ and see what value of $b$ makes the equation $a^2 + b^2 = 1521$ true. We can rewrite this equation as:

$b^2 = 1521 - a^2$

If we plug in $a=1$, we get:

$b^2 = 1521 - 1^2 = 1520$

Now we need to find a perfect square that is less than or equal to 1520, since that will give us a value of $b$ that is an integer. The largest perfect square that is less than or equal to 1520 is $36^2 = 1296$, so we can try plugging in $b=36$:

$36^2 = 1296$

$1^2 + 36^2 = 1297$

This is close, but not quite right – we need the sum of the squares to be 1521, not 1297. We can try again with a larger value of $a$, and keep going until we find a value that works. This process can be a bit tedious, but fortunately there is a shortcut – we can use the fact that $a$ and $b$ must be the lengths of sides of a triangle to narrow down our choices.

Specifically, we know that in a triangle, the length of any side must be less than the sum of the lengths of the other two sides. In this case, we have a right triangle with hypotenuse length 39, so the length of each leg must be less than 39. This means that $a$ and $b$ must both be less than 39.

We can use this fact to quickly eliminate many of the possibilities. For example, if $a=1$, we know that $b^2 = 1520$, which means that $b$ must be greater than 39 (since $6^2 = 36$ and $7^2 = 49$). This tells us that $a$ must be at least 7 in order for there to be any hope of finding a value of $b$ that works.

Using this approach, we can quickly narrow down the possibilities and find that the only value of $a$ that works is 15. If we plug in $a=15$, we get:

$b^2 = 1521 - 15^2 = 216$

$b = \sqrt{216} = 6\sqrt{6}$

So the length of the shorter leg is $\boxed{15}$ units.

The values of p, q, and r are p = 2, q = 5, and r = 3, respectively.

Given that the lowest common multiple (LCM) of A and B is 2250, and the prime factorization of A is A = 2 × p × q¹, and the prime factorization of B is B = 2 × p² × q², we can compare the prime factorizations to determine the values of p, q, and r.

From the prime factorization of 2250 (2 × 3² × 5³), we can observe the following:

The prime factor 2 appears in both A and B.

The prime factor 3 appears in A.

The prime factor 5 appears in A.

Comparing this with the prime factorizations of A and B, we can deduce the following:

The prime factor p appears in both A and B, as it is present in the common factors 2 × p.

The prime factor q appears in both A and B, as it is present in the common factors q¹ × q² = q³.

From the above analysis, we can conclude:

The standard deviation for the random variable X, the number of wins, is approximately 0.10341.

Probability of winning a certain lottery \(= 1/51,949\)

560 times were played overall.

Let X represent the random variable that represents the number of victories out of 560 plays.

The probability of winning in one play is \(p = 1/51,949\). The probability of not winning in one play is \(q = 1 - p\)

\(q = (51,949 - 1) / 51,949\)

\(q = 51,948 / 51,949.\)

What X should actually be is:

\(E(X) = np\)

\(E(X) = 560 * (1/51,949)\)

\(E(X) = 0.010793\)

The variance of X is:

\(Var(X) = npq\)

\(Var(X) = 560 * (1/51,949) * (51,948/51,949)\)

\(Var(X) = 0.010699\)

The value of X's standard deviation is

\(SD(X) = \sqrt{Var(X)}\)

\(SD(X) = \sqrt{0.010699}\)

\(SD(X) = 0.10341\)(approx)

Therefore, the standard deviation for the random variable X, the number of wins, is approximately 0.10341.

The process takes approximately 14 iterations to reach the desired accuracy.

The Bisection Method will take approximately 14 iterations to find the approximate root of the equation within an error tolerance of 0.001. The mathematics calculations involve finding the midpoint of a given interval [a, b] and then determining whether the midpoint is a root of the equation. If it is not a root, then the interval is divided into two halves, and the process is repeated on the subinterval where the sign of the function changes. This process is repeated until the midpoint is within the desired error tolerance.

To calculate the number of iterations required, we begin by noting that the initial interval used is [1, 0]. The midpoint of this interval is 0.5. This value is then plugged into the function to determine if it is a root. Since it is not, the interval is then divided into two halves and the process is repeated. This process is repeated until the midpoint is within the desired error tolerance of 0.001. In this case, it takes approximately 14 iterations to reach the desired accuracy.
