Step-by-step explanation:

The common ratio = -10/4 = -5/2 and the first term is 4.

The sigma notation is:

n=6

∑       4(-5/2)^n-1.   (answer).

n=1

Answer:

[tex]\sum_{n=1}^{n=6} 4(\frac{-5}{2} )^{n-1}[/tex]  

Step-by-step explanation:

We are given the geometric series [tex]4 + -10+ 25+ -62.5+ 156.25+ -390.625[/tex]

General geometric series is of the form

[tex]a, ar, ar^2, ar^3, ar^4,\text{ and so on}[/tex], where a is the first term and r is the common ration.

The common ratio for given geometric series is [tex]\frac{\text{Second Term}}{\text{First Term}}[/tex] = [tex]\frac{-10}{4} = \frac{-5}{2}[/tex]

[tex]a = 4\\r = \frac{-5}{2}[/tex]

To write the series in summation form we use:

[tex]\sum_{k=0}^{k=n} a(r)^{k}[/tex]

Thus, the given geometric series is

[tex]\sum_{n=1}^{n=6} 4(\frac{-5}{2} )^{n-1}[/tex]

Answer:

[tex]x=5[/tex] and [tex]y=2[/tex].

Step-by-step explanation:

We have been given a system of equations. We are asked to solve our given system.

[tex]x+y=7...(1)[/tex]

[tex]2x+3y=16...(2)[/tex]

From equation (1), we will get:

[tex]x=7-y[/tex]

Upon substituting this value in equation (2), we will get:

[tex]2(7-y)+3y=16[/tex]

[tex]14-2y+3y=16[/tex]

[tex]14+y=16[/tex]

[tex]14-14+y=16-14[/tex]

[tex]y=2[/tex]

Now, we will substitute [tex]y=2[/tex] in equation (1).

[tex]x+2=7[/tex]

[tex]x+2-2=7-2[/tex]

[tex]x=5[/tex]

Therefore, the point [tex](5,2)[/tex] is solution for our given equation.

Answer:

B. 24 yd^2

Step-by-step explanation:

Let A denote the area of the smaller figure:

We can determine the ratio of both lengths and areas as:

3:5 :: A:40

As the areas of figures vary directly with their lengths and widths so the proportion will be direct proportion.

Converting into fractions will give us:

3/5 = A/40

Now we have to find the value of A for the area of smaller figure.

Cross multiplication will give us:

3*40 = 5A

=> 120 = 5A

=> 120/5 = 5A/5

So,

A = 24 yd^2

Answer:

|x-22| < 2

The < has an underline below it

The absolute value inequality that represents the average height range of a golden retriever (20-24 inches) is |h - 22| <= 2, where h represents any height within the range. This means that the difference between any height in the range and the midpoint (22 inches) is at most 2 inches.

To write the average height range of a golden retriever as an absolute value inequality, we need to first find the midpoint of the range and then use that to express the distance from any height in the range to that midpoint. In this case, the average height range for a golden retriever is 20-24 inches. The midpoint of the range is (20 + 24) / 2 = 22 inches. So, any height h in the range satisfies |h - 22| <= 2. This is because the maximum difference between any height in the range and the midpoint is 2 inches (24 - 22 or 22 - 20).

These I's are being used as sticks

lets say i have 40 sticks then i add 55 more sticks to them

IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII + IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII If i were to reverse the sequence and use the 55 sticks and add 44 sticks to them it would be the same as me having 44 sticks and adding 55 more.

By commutative property, the following which is equal to 40 + 55 is Option(D) 55 + 40.

The commutative property is a math rule that says that the order in which we find the sum of the numbers does not change the sum up value of the numbers.

By the statement,

A + B = B + A , where A and B are any numbers

The original expression given is 40 + 55 .

Therefore by commutative property, the equivalent expression is -

40 + 55 = 55 + 40

○ The graph of y = -2x² + 3 opens downward and is shifted up.

Step-by-step explanation:

According to the Quadratic Equation, y = Ax² + Bx + C, C acts like a y-intercept, and in this case, since both graphs shift up [because both are positive values], we do not pay attention to those. Now, we come over to our A, which makes a BIG difference because both graphs open in opposite directions [one negative, one positive]. With this being stated, we have our answer.

Answer:

A. 0

Step-by-step explanation:

Nothing can be equal to itself if you subtract 9 from it.

Final answer:

The equation X = X - 9 yields a contradiction upon simplification (0 = -9), indicating that there are no solutions.

Explanation:

To determine the number of solutions for the given equation, we start by inspecting it closely:

X = X - 9

If we attempt to solve for X, we will subtract X from both sides of the equation:

0 = -9

This is a contradiction since 0 does not equal -9. Therefore, the given equation has no solution. Other examples of equations can have one solution, such as X = 1, or have two solutions, such as quadratic equations like x = 4.133 or 9.435. But in this case, the equation does not balance and therefore has no solutions.

The correct answer is:

A. 0

The quotient of the rational expressions given is obtained by converting the division to multiplication by the reciprocal leading to \((\frac{3x \times (x+5)}{2x \times (2x+5)})\). The final simplification depends on specific values of x.

The question asks to find the quotient of the following rational expressions: \((\frac{3x}{2x+5}) \div (\frac{2x}{x+5})\). To solve this, we first recall that dividing by a fraction is the same as multiplying by its reciprocal. Therefore, the problem becomes \((\frac{3x}{2x+5}) \times (\frac{x+5}{2x})\).

We simplify this further by multiplying the numerators together and the denominators together: \((\frac{3x \times (x+5)}{2x \times (2x+5)})\).

To solve the more difficult problem, as hinted, we might consider factoring or simplifying further. However, the key calculation here reveals that the certain factors in the numerator and denominator might not simplify directly in this expression, leading to a more nuanced understanding of rational expressions. As such, detailed simplification depends on the specific values of x and further factorization may not lead to a simpler form without more context.

The correct answer is: [tex]\text { B. } \frac{3 x+15}{4 x+10}[/tex].

To find the quotient of the given rational expressions, you divide the first rational expression by the second one.

[tex]\frac{\frac{3 x}{2 x+5}}{\frac{2 x}{x+5}}=\frac{3 x}{2 x+5} \cdot \frac{x+5}{2 x}[/tex]

Now, you can simplify this expression:

[tex]=\frac{3 x(x+5)}{2 x(2 x+5)}[/tex]

Cancel out x from both numerator and the denominator.

[tex]=\frac{3 (x+5)}{2 (2 x+5)}[/tex]

[tex]=\frac{3x+15}{4x+10}[/tex]

This value matches with the option B. Thus, B is the correct answer.

Complete Question:

Which of the following is the quotient of the rational expressions shown below?

[tex]\frac{3 x}{2 x+5} \div \frac{2 x}{x+5}[/tex]

[tex]\text { A. } \frac{4 x^2+10 x}{3 x^2+15 x}[/tex]

[tex]\text { B. } \frac{3 x+15}{4 x+10}[/tex]

[tex]\text { D. } \frac{3}{4}[/tex]

The expression log 5 + log 2 can be combined using the property that the logarithm of a product is equal to the sum of the logarithms, which simplifies to log 10. Since log 10 is equal to 1, the solution to the expression is 1.

To solve the expression log 5 + log 2 using the logarithmic theorems, we can apply one of the fundamental properties of logarithms. Specifically, the logarithm of a product of two numbers is equal to the sum of the logarithms of those two numbers (log xy = log x + log y). Applying this property to our expression, we can combine the two logarithms as follows:

log 5 + log 2 = log (5 x 2)

Now, we can easily calculate the combined term:

log (5 x 2) = log 10

Since the base of the logarithm is not specified, we can assume it is 10 (common logarithm). Therefore, we can simplify further:

log 10 = 1

Thus, the solution to the given expression is 1.

Answer:

Nearly 23.8%

Step-by-step explanation:

The word ALGEBRA consists of letters A, L, G, E, B, R and A (2 letters A and 5 letters other than A).

The probability that the first letter chosen will be other than A is

[tex]\dfrac{5}{7}[/tex]

Then 2 letters A and 4 letters other than A left (6 letters in total). The probabilty that the second letter chosen is A is

[tex]\dfrac{2}{6}=\dfrac{1}{3}[/tex]

Hence, the probability of choosing a letter other than A and then choosing an A is

[tex]\dfrac{5}{7}\cdot \dfrac{1}{3}=\dfrac{5}{21}\approx 23.8\%[/tex]

The probability of first drawing a letter other than 'A' and then drawing an 'A' from the word ALGEBRA is approximately 23.81%. This is determined by calculating the individual probabilities and then multiplying them together.

The word ALGEBRA has 7 letters. The probability of choosing a letter other than 'A' means we are considering 5 valid letters out of the 7. Therefore, the probability is 5/7. Then, looking for an 'A' within the remaining 6 letters (after one letter is already taken), we see there are 2 'A' letters left, so the probability is 2/6 or simplified as 1/3.

Therefore, the combined probability of both these events happening is the product of their individual probabilities. We multiply the fractions: 5/7 * 1/3 = 5/21 = 0.238095. Translating that fraction into a percentage, we multiply by 100% to get approximately 23.81%.
