Answer:

Step-by-step explanation:

Question 1 :

The statement that best describes the solutions of a two-variable equation is (1) The ordered pairs must lie on the graphed equation. This means that any ordered pair (x,y) that satisfies the equation will corresponds to a point on the graph of the equation. In other words, if we plot all the points (x,y) that make the equation true, we will obtain the graph of the equation. Any points that do not lie on the graph is not a solution to the equation. Therefore, when solving a two-variable equation, we need to find the values of x and y that make the equation true and plot those points on the graph to visualize the solutions.

Question 2 :

To use the arithmetic sequence formula, we need to know the first term (a1), the common difference (d), and the desired term (an). In this case, we are given the first term as 4 and the common difference as 3 (since each term is increasing by 3). To find the 10th term, we would replace the variable "n" with 10 in the formula. Therefore, to determine the 10th term of this sequence, we would use the formula:

a10 = a1 + (n-1)d

a10 = 4 + (10-1)*3

a10 = 4 + 27

a10 = 31

Thus, the 10th term of the given sequence is 31.

Question 3 :

The formula an = al + (n-1)d is used to determine the nth term in an arithmetic sequence, where "a" represents the first term in the sequence, "n" represents the term number being solved for, and "d" is the common difference between terms. The formula essentially states that to find any term in an arithmetic sequence, one must add the common difference between terms multiplied by the number of terms-1 to the value of the first term. This formula can be applied to various situations, such as determining the total cost of goods sold in a business with a constant markup percentage, or calculating the number of days it will take to save a given amount of money with a fixed monthly contribution. By understanding the principles behind the formula, individuals can successfully solve problems involving arithmetic sequences in a variety of contexts.

Thus, the intermediate step in the form (x+a)² = b as a result of completing the square for the given equation is - (x + 10)² = 1 /3.

A quadratic equation can be made together into perfect square trinomial simply adding or removing elements from both sides, a technique known as "completing the square."

You can use the square's completion as another mathematical tool to solve a variety of problems:

Given expression:

-3x² - 298 = 60x - 1

isolating the x values:

-3x² - 60x = 298 - 1

-3x² - 60x = 299

Taking -3 common from the left hand side:

-3(x² + 20x) = 299

x² + 20x = - 299/3

This, can be written as:

x² + 2*10x = - 299/3

add both side by 100

x² + 2*10x + 100 = - 299/3 + 100

On simplification:

(x + 10)² = (-299 + 300) /3

(x + 10)² = 1 /3

Comparing obtained expression with the given form: (x+a)²=b

There seems to be an error in the expression for P3(x). It appears to be missing an exponent for the second term.

Assuming that the correct expression is P3(x) = x^4 - 21x^2 + 20x, we can analyze its properties.

The degree of the polynomial P3(x) is 4, which means its graph will have at most 4 x-intercepts and at most 3 turning points.

To find the x-intercepts, we set P3(x) equal to zero and solve for x:

x^4 - 21x^2 + 20x = 0

x(x^3 - 21x + 20) = 0

Using the factor theorem or synthetic division, we can find that x = 0 is a root of the polynomial, so (x-0) is a factor. The remaining cubic factor can be factored as (x-1)(x-4)(x+5).

Therefore, the x-intercepts of the graph of P3(x) are x = 0, x = 1, x = 4, and x = -5.

As for the y-intercept, we can find it by setting x = 0:

P3(0) = 0^4 - 21(0)^2 + 20(0) = 0

So the y-intercept is (0,0).

To determine the turning points, we can find the critical points by taking the derivative of P3(x) and setting it equal to zero:

P3'(x) = 4x^3 - 42x + 20

4x^3 - 42x + 20 = 0

Solving this equation yields three critical points: x ≈ -1.23, x ≈ 0.58, and x ≈ 2.65.

We can use the second derivative test to determine the nature of these critical points. The second derivative is:

P3''(x) = 12x^2 - 42

At x ≈ -1.23 and x ≈ 2.65, the second derivative is negative, indicating that these are local maxima. At x ≈ 0.58, the second derivative is positive, indicating that this is a local minimum.

Therefore, the graph of P3(x) has a local maximum at (approximately) (-1.23, P3(-1.23)), a local minimum at (approximately) (0.58, P3(0.58)), and a local maximum at (approximately) (2.65, P3(2.65)).

From the given information about the vertices of the quadrilateral, the point at which the PQRS quadrilateral will be made a rectangle is S(17/14, -1/7).

https://brainly.com/question/12871911

#SPJ1

The answer is option c.) S(-8,2).

A closed quadrilateral has four sides, four vertices, and four angles. It is a form of polygon. In order to create it, four non-collinear points are joined. Quadrilaterals always have a total internal angle of 360 degrees.

For PQRS to be a rectangle, its opposite sides must be parallel and have equal length. We can find the length of PQ and RS using the distance formula:

PQ = √[(Qx - Px)² + (Qy - Py)²]

  = √[(-3 - (-5))² + (6 - 7)²]

  = √[4 + 1]

  = √[5]

RS = √[(Sx - Rx)² + (Sy - Ry)²]

  = √[(-8 - (-6))² + (2 - 0)²]

  = √[4 + 4]

  = √[8]

Since PQ and RS are not equal, we need to find a point S such that PQRS has equal sides. Moreover, the diagonals of a rectangle bisect each other. Hence, we can use the midpoint formula to find a point that bisects PR:

M = [(-5 - 6)/2, (7 + 0)/2]

 = (-11/2, 7/2)

Let's consider each option:

a.) S(-4,-1)

The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-4, -1) cannot be a point of RS.

b.) S(-7,2)

The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-7 + 6) = -2, so S(-7, 2) cannot be a point of RS.

c.) S(-8,2)

The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (2 - 0)/(-8 + 6) = 1, so S(-8, 2) could be a point of RS. Moreover, the distance from S to the midpoint of PR is:

√[(-11/2 - (-8))² + (7/2 - 2)²]

= √[25/4 + 9/4]

= √[34]/2

This is equal to the length of PQ, so PQRS could be a rectangle with S(-8, 2).

d.) S(-8,1)

The slope of PQ is (6 - 7)/(-3 + 5) = -1/2, so the slope of RS must be -1/2 as well. The slope of RS is (1 - 0)/(-8 + 6) = -1, so S(-8, 1) cannot be a point of RS.

Therefore, the answer is option c.) S(-8,2).

Answer:

the product of (3-2x)(2x+1)(x-5) is -4x^3 + 26x^2 - 19x - 75.

Step-by-step explanation:

To find the product, we need to multiply these three expressions:

(3 - 2x)(2x + 1)(x - 5)

Let's start by multiplying the first two expressions using the distributive property:

(3 - 2x)(2x + 1) = 6x - 4x^2 + 3 - 2x

Now we can multiply this result by the third expression using the distributive property again:

(6x - 4x^2 + 3 - 2x)(x - 5) = 6x^2 - 34x + 15x - 75 - 4x^3 + 20x^2

Simplifying this expression by combining like terms, we get:

-4x^3 + 26x^2 - 19x - 75

Therefore, the product of (3-2x)(2x+1)(x-5) is -4x^3 + 26x^2 - 19x - 75.

The probability of getting a multiple of 2 or a multiple of 3s:

P = 0.67

The probability is equal to the quotient between the number of outcomes for the given event and the total number of outcomes, which in this case are 12.

The multiples of 2 and the multiples of 3 are

{2, 3, 4, 6, 8, 9, 10, 12}

So 8 out of the total of 12 outcomes make the event true, then the probability we want to get is the quotient between these numbers:

What is simple interest?

Before delving further into the concept of simple interest, it is worth noting that it is a straightforward method for calculating interest on money, whereby interest is added at a constant rate for each time period and always to the initial principal amount. When we deposit our money into a bank, we can earn interest on our investment. Simple interest is one type of interest that banks may offer.

The formula for simple interest is:

I = P * r * t

where:

I = interest earned

P = principal (initial amount)

r = interest rate per year (as a decimal)

t = time (in years)

Substituting the given values, we have:

P = $9,750

r = 0.055 (since the interest rate is 5.5%)

t = 3

I = $9,750 * 0.055 * 3

we do not have convincing statistical evidence that women pay more than men for the same transmission repair

To determine whether the data provide convincing statistical evidence that women pay more than men we do not have convincing statistical evidence that women pay more than men for the same transmission repair for the same transmission repair, we can perform a hypothesis test.

Null hypothesis: The mean repair cost for women is the same as the mean repair cost for men.

Alternative hypothesis: The mean repair cost for women is greater than the mean repair cost for men.

We can use a two-sample t-test for the difference in means, assuming equal variances.

The test statistic is given by:

t = (xbar1 - xbar2) / (s_p * sqrt(1/n1 + 1/n2))

where xbar1 and xbar2 are the sample means, s_p is the pooled standard deviation, and n1 and n2 are the sample sizes.

The degrees of freedom is given by:

df = n1 + n2 - 2

Using the data given, we have:

xbar = 2542.86, xbar2 = 2469.29

s1 = 691.27, s2 = 599.77

n1 = n2 = 7

First, we can calculate the pooled standard deviation:

s_p = sqrt(((n1-1)*s1^2 + (n2-1)*s2^2) / (n1 + n2 - 2))

s_p = sqrt(((6)*691.27^2 + (6)*599.77^2) / (7 + 7 - 2))

s_p = 644.47

Then, we can calculate the t-statistic:

t = (xbar 1 1 - xbar2) / (s_p * sqrt(1/n1 + 1/n2))

t = (2542.86 - 2469.29) / (644.47 * sqrt(1/7 + 1/7))

t = 0.97

Using a t-distribution table with df = 12 and a significance level of 0.05, the critical value for a one-tailed test is 1.7823. Since our t-statistic is less than the critical value, we fail to reject the null hypothesis.

Therefore, we do not have convincing statistical evidence that women pay more than men for the same transmission repair
