To find the number of days it will take for Juliana's investment to grow, we can use the formula for simple interest

I = P * r * t.

I = interest earned
P = principal amount (initial investment)
r = interest rate per year (in decimal form)
t = time in years In this case,

Juliana's principal amount (P) is $3,300, the interest rate (r) is 6.25% or 0.0625, and she wants to reach $3,450. We need to solve for t. $3,450 = $3,300 * 0.0625 * t Divide both sides of the equation by ($3,300 * 0.0625) to isolate t:
t = $3,450 / ($3,300 * 0.0625)
t = 17 So it will take Juliana approximately 17 days for her investment to grow to $3,450.

Answer:

A, E

Step-by-step explanation:

lets first solve the equation using distributive property:

-3(x-2)=4x-2(x-1)

-3x+6=4x-2x+2

-3x+6=2x+2    (E)

Now move the like terms on one side:

-5x=-4             (A)

Answer: c

Step-by-step explanation:

A is 190 divided by 125

B is 190 multiplied with 125 (product of the two numbers)

D is the sum of 190 and 125 (addition)

the difference will be found by subtracting the smaller number from the bigger number

Answer:

(x+2)(9x+6)

Step-by-step explanation:

This is the whole process. Skip down to the bolded important part if you want.

Going to quickly expand it again:

\(9x(x+2)+6(x+2)\\9x^2+18x+6x+12\\9x^2+24x+12\)

This is in the form of:

\(ax^2+bx+c\)

To factor a trinomial in this form, you need to find 2 numbers that multiply together to make \(ac\), and also add together to make \(b\).

In this case,

\(ac=9*12=108\\b=24\\\\18*6=108=ac\\18+6=24=b\)

those 2 numbers are 18 and 6.

Then, in the above, expanded equation, you need to split b into 2 numbers, from 24 into 18 and 6.

\(9x^2+24x+12\\9x^2+18x+6x+12\)

Then, split the equation in half and factor each half individually.

\((9x^2+18x)+(6x+12)\\9x(x+2)+6(x+2)\)

Important part ==========

Now, we're right back at where we started with your question. All we need to do now is factor out the (x+2).

\(9x(x+2)+6(x+2)\\(x+2)(9x+6)\)

And you're done, that's all.

The solutions to the quadratic equation x² = -7x - 8 are x equals  \(\frac{-7 - \sqrt{17}}{2}, \frac{-7 + \sqrt{17}}{2}\).

Given the quadratic equation in the question:

x² = -7x - 8

To find the solutions of the quadratic equation x² = -7x - 8, we can rearrange it into standard quadratic form, which is ax² + bx + c = 0, and apply the quadratic formula.

x² = -7x - 8

x² + 7x + 8 = 0

a = 1, b = 7 and c = 8

Plug these into the quadratic formula: ±

\(x = \frac{-b \± \sqrt{b^2 -4(ac)}}{2a} \\\\x = \frac{-7 \± \sqrt{7^2 -4(1*8)}}{2*1} \\\\x = \frac{-7 \± \sqrt{49 -4(8)}}{2} \\\\x = \frac{-7 \± \sqrt{49 - 32}}{2} \\\\x = \frac{-7 \± \sqrt{17}}{2} \\\\x = \frac{-7 - \sqrt{17}}{2}, \frac{-7 + \sqrt{17}}{2}\)

Therefore, the values of x are \(\frac{-7 - \sqrt{17}}{2}, \frac{-7 + \sqrt{17}}{2}\).

Therefore , the solution of the given problem of angles comes out to be

120° is the measure of interior angle of regular polygon of 6 sides.

An angle is a structure in Euclidean geometry made up of two rays, called the sides of the loops, that split at the apex of the angle and indeed the vertex, which is located in the middle. A combination of two rays may result in an angle being created inside the plane in which they are positioned. The combination of two planes also produces an angle. These are referred to as dihedral angles. Two line rays with end points can be arranged in a variety of ways to create angles in two dimensions.

The total number of possible ways to create a license plate with 2 letters followed by 3 numbers if no repetition is 4,680,00.

To calculate the number of ways to create a license plate with 2 letters followed by 3 numbers, we need to consider two separate parts: the number of ways to choose the two letters, and the number of ways to choose the three numbers. Since no repetition is allowed, we have to take this into account in both parts.

For the first part, we have 26 choices for the first letter and 25 choices for the second letter, since we cannot choose the same letter twice.

For the second part, we have 10 choices for each of the three numbers. Again, we cannot choose the same number twice, so we have to decrease the number of choices by 1 for each subsequent number.

Thus, the total number of ways to create a license plate with 2 letters followed by 3 numbers is:

26 x 25 x 10 x 9 x 8 = 468,000

If no repetition of characters is allowed, then the number of possible ways to create a license plate with 2 letters followed by 3 numbers can be calculated as follows:

There are 26 choices for the first letter (A-Z).

There are 25 choices for the second letter (since no repetition is allowed).

There are 10 choices for the first number (0-9).

There are 9 choices for the second number (since no repetition is allowed).

There are 8 choices for the third number (since no repetition is allowed).

Therefore, the total number of possible ways to create a license plate with 2 letters followed by 3 numbers if no repetition is allowed is:

26 x 25 x 10 x 9 x 8 = 4,680,00

Answer:

Please type or attach a question to be answered. Currently, all you have is as a question is the statement "Breyelle is planning on purchasing a new sports utility vehicle."

It is true that the existence of two local maxima does not guarantee the presence of a local minimum. It is possible for a function to have multiple local maxima and no local minimum.

For example, consider the function f(x,y) = x^4 - 4x^2 + y^2. This function has two local maxima at (2,0) and (-2,0), but no local minimum. Therefore, the statement "if f(x,y) has two local maximal, then f must have a local minimum" is false. The presence or absence of local maxima and minima depends on the behavior of the function in the immediate vicinity of a point, and cannot be determined solely based on the number of local maxima. It is possible for a function to have an infinite number of local maxima and minima, or none at all. Therefore, it is important to carefully analyze the behavior of a function in order to determine the presence or absence of local extrema.

A statistical test conducted to determine whether to reject or not reject a hypothesized probability distribution for a population is known as a test of significance

Statistical Test

A statistical test provides a mechanism for making quantitative decisions about a process or processes. The intent is to determine whether there is enough evidence to reject a conjecture or hypothesis about the process.

A test of significance is a formal procedure for comparing observed data with a claim (also called a hypothesis), the truth of which is being assessed. The claim is a statement about a parameter, like the population proportion p or the population mean µ.

Hypothesized Probability Distribution

To hypothesis test with the binomial distribution, we must calculate the probability, p , of the observed event and any more extreme event happening. We compare this to the level of significance α . If p>α then we do not reject the null hypothesis. If p<α we accept the alternative hypothesis.

The test is a statistical test .The test is used to accept or reject an hypothesis. The statistical test that has the above features is the test of significance
