Answer 1

Answer:

the number of positive real roots is one

the number of negative real roots is one

I not sure I was right

Step-by-step explanation:

[tex]x^{3} +5x^{2} -3x+7[/tex]

it changed the sign in the second to the third term,so,it was one root

[tex]-x^{3} +5x^{2} +3x+7[/tex]

Change the coefficients of odd items, and the signs of the first to second items change, so there is also a root.

Answer 2

Answer:

Maximum of 2 positive real rootsExactly 1 negative real root

Step-by-step explanation:

Descartes' Rule of Signs tells us the maximum number of positive and negative real roots in a polynomial function.

Positive root case

[tex]\begin{aligned}p(x)&=(x)^3+5(x)^2-3(x)+7\\ &=+x^3+5x^2-3x+7\end{aligned}[/tex]

Check the signs of the coefficients. As there are 2 sign changes, the maximum possible number of positive roots is 2.

However, as some pairs of roots may be complex, count down by two's to find the complete list of the possible number of roots.

So there may be as many as 2 real roots or there might also be no real roots (zero).

Negative root case

[tex]\begin{aligned}p(-x)&=(-x)^3+5(-x)^2-3(-x)+7\\&=-x^3+5x^2+3x+7\end{aligned}[/tex]

Check the signs of the coefficients.  As there is one sign change, the maximum possible number of negative roots is 1.  We can't count down by two's since this would give us a negative number. Therefore, there is exactly 1 negative root.

Note:  There is one real negative root of the given function at x ≈ -5.74 and two complex roots at x = 0.37 + 1.04i  and  x = 0.37 - 1.04i.

Which of the following statements is true regarding a scatter diagram?
a. It provides very little information about the relationship between the regression variables.
b. It is a plot of the independent and dependent variables.
c. It is a line chart of the independent and dependent variables.
d. It has a value between -1 and +1.
e. It gives the percent of the variation in the dependent variable that is explained by the independent variable.

Answers

Option B is correct. It is a plot of the independent and dependent variables.

A scatter diagram is a type of plot or graph that uses Cartesian coordinates to display the values of two variables for a set of data. It is a simple yet powerful way to visualize the relationship between two variables.

The points on the plot represent the values of two variables, the independent variable (X-axis) and the dependent variable (Y-axis). Scatter diagrams provide a visual representation of the relationship between the two variables, which makes it easier to identify patterns such as linear or non-linear relationships.

They also can show correlations, or lack thereof, between two or more variables. Additionally, scatter diagrams can provide insight into the strength of the relationship between the two variables as well as how much of the variation in the dependent variable is explained by the independent variable. For example, a correlation coefficient of 1 indicates a perfect linear relationship, while a correlation coefficient of 0 indicates no relationship between the two variables.

Mary plants roses in 1/4 of her garden. She also plants some tulips in her garden. She has 1/12 of the garden left to plant more flowers. What fraction of Mary's garden has tulips?

Answers

Let's represent the fraction of Mary's garden that has tulips as x. The fraction of Mary's garden that has roses is 1/4, and the fraction of Mary's garden that is left to plant more flowers is 1/12. We can set up the equation 1/4 + x + 1/12 = 1, since the total fraction of Mary's garden must add up to 1.

Solving this equation for x, we get:
1/4 + x + 1/12 = 1
x = 1 - 1/4 - 1/12
= 3/4 - 1/12
= 3/12 + 5/12
= 8/12
= 2/3

Therefore, the fraction of Mary's garden that has tulips is 2/3.

Which statement could describe the diver’s movements?

Answers

Answer: The diver descended 20 meters below sea level and then ascended 8 meters.

Step-by-step explanation: The expression 2 + (-20) + 8 describes the diver's movements in relation to sea level. The first number, 2, represents the diver's initial position at sea level. The second number, -20, represents the diver's descent below sea level by 20 meters. The third number, 8, represents the diver's ascent back up to sea level. This can be interpreted as the diver starting at sea level, descending 20 meters below sea level, and then ascending 8 meters back up to sea level.

Answers

If the data display is strongly skewed right, it means that there are relatively more households with a higher number of children compared to households with a lower number of children. This means that the median value is likely to be higher than the mean value of 3 children per household.

Possible values for the median could be 4, 5, or even higher. It is not possible to determine the exact value of the median without more information about the distribution of the data. However, it is reasonable to assume that the median could be 4 or 5 children per household in this case.

3 The sum of two numbers is 6, and the sum of their squares is 28. Find these numbers.

Answers

Answer:

The possible pairs of numbers that satisfy the given conditions are (x, y) = (4, 2) and (x, y) = (8, -2).

Step-by-step explanation:

To solve this problem, we can use algebra. Let's call the two numbers x and y. We are given that x + y = 6 and x^2 + y^2 = 28. We can square the equation x + y = 6 to get x^2 + 2xy + y^2 = 36. We can then subtract the equation x^2 + y^2 = 28 from the equation x^2 + 2xy + y^2 = 36 to get 2xy = 8. We can then divide both sides by 2 to get xy = 4.

We can then use the equation x + y = 6 to write x = 6 - y, which we can substitute into the equation xy =  to get (6 - y)y = 4. Solving this equation for y yields y = 2 or y = -2.

If y = 2, then x = 6 - y = 6 - 2 = 4, so the two numbers are x = 4 and y = 2. If y = -2, then x = 6 - y = 6 + 2 = 8, so the two numbers are x = 8 and y = -2. Therefore, the possible pairs of numbers that satisfy the given conditions are (x, y) = (4, 2) and (x, y) = (8, -2).

Answers

The equation that shows the relationship is y = 6 + x

How to determine the equation that shows the relationship?

From the question, we have the following parameters that can be used in our computation:

Initial number of pieces = 6

Additional number of pieces per week = 1

The equation that shows the relationship is represented as

Number of pieces = Initial number of pieces + Additional number of pieces per week * Number of weeks

Substitute the known values in the above equation, so, we have the following representation

Number of pieces = 6 + 1 * Number of weeks

So, we have

Number of pieces = 6 + Number of weeks

A ball is projected into the air. Its height at time, t, is given by the equation h=-16t^2 + 100t + 2. When will the ball return to the ground?

A.0.02 sec
B. 6.3 sec
C. 6.5 sec
D. 16 sec

Answers

Answer:

The ball will return to the ground at t = 16 seconds, so the correct answer is D.

Step-by-step explanation:

To find when the ball will return to the ground, we need to find the time at which the ball's height is equal to 0. We can do this by setting the height equation equal to 0 and solving for t.h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-2 = -16t^2 + 100t

-0.125t = -2

t = 16

Answer:

B. 6.3 sec

Step-by-step explanation:

To find the time when the ball will return to the ground, we need to find the value of t when h is equal to 0 (since height = 0 means the ball is on the ground). We can do this by substituting 0 for h in the given equation and solving for t.

So, let's start by substituting 0 for h:

h = -16t^2 + 100t + 2

0 = -16t^2 + 100t + 2

-16t^2 + 100t + 2 = 0

This is a quadratic equation, which we can solve using the quadratic formula:

t = (-100 +/- sqrt(100^2 - 4(-16)(2)) ) / (-2(-16))

t = (-100 +/- sqrt(10000 + 128)) / 32

t = (-100 +/- sqrt(10128)) / 32

t = (-100 +/- 100.64) / 32

t = (200.64) / 32

t = 6.3125

Since the ball is projected into the air and then falls back down to the ground, the time when it returns to the ground must be a positive value. Therefore, the solution to the problem is t = 6.3 sec

B (x-1)(-7x+10)
C(x-1)(7x+10)
D(x-7)(x+10)
E(7x-1)(x+10)

Answers

Answer:

The correct answer is A (x+1)(7x-10).  

Step-by-step explanation:

To determine the dimensions of a rectangular poster that will cover an area represented by 7x² + 3x - 10, we need to find the factors of the expression 7x² + 3x - 10 that will give us the length and width of the poster.

One way to do this is to factor the expression 7x² + 3x - 10 using the difference of squares method. We can write the expression as follows:

7x² + 3x - 10 = (7x² + 3x) - 10

To factor (7x² + 3x) - 10, we can write the expression as the difference of squares:

(7x² + 3x) - 10 = (7x² + 3x + 10) - (10 + 10)

To simplify the expression, we can complete the square for the terms in parentheses:

(7x² + 3x + 10) - (10 + 10) = (7x² + 3x + 10) - 20

To complete the square, we need to add and subtract the square of half the coefficient of the x term, which is (3/2)² = 9/4. We can rewrite the expression as follows:

(7x² + 3x + 10) - 20 = (7x² + 3x + 10 + 9/4) - (20 - 9/4)

To simplify the expression, we can factor the terms in parentheses:

(7x² + 3x + 10 + 9/4) - (20 - 9/4) = [(7x² + 3x + 10 + 9/4) - (20 - 9/4)]

To simplify the expression further, we can factor out a common factor:

[(7x² + 3x + 10 + 9/4) - (20 - 9/4)] = (x + 1)(7x - 10)

From the given options, the expression that represents the area of the rectangular poster is (x+1)(7x-10), which is equivalent to 7x² + 3x - 10. We can verify this by multiplying (x+1)(7x-10) to get 7x² + 3x - 10. Therefore, the correct answer is A (x+1)(7x-10).

Answers

The amount of interest Maria owes after 6 month of graduation, if she take a subsidized loan of $5,000 and unsubsidized loan of $4,500 is $508.75.

Therefore, the answer is $509.

Subsidized loan

Here, the time period is considered only after graduation, so time period is 6 months, that is 0.5 year. We know simple interest formula where P is the principal amount, r is annual interest rate and n time period in years.

I = P×r×n

Therefore I₁ =  5000 × 0.055 × 0.5

I₁ = 137.5

Unsubsidized loan

Here the time period is considered from the time the loan taken, so time period is one year of graduation plus 0.5 year, i.e. n = 1.5yrs.

Therefore, I₂ = 4500 × 0.055 × 1.5

I₂ = 371.25

Therefore total interest for both the loan is

I = I₁ + I₂

I = 137.5 + 371.25

I = 508.75

I ≈ $509
