Algebra I

Slope-Intercept Form: y = mx + b

Transformations of graphs

Step-by-step explanation:

Step 1: Define

f(x) = x + 1

g(x) = -x + 4

Step 2: Define

Multiplying -1 to x flips it over the x-axis, or known as a reflection. There is no vertical shrink/stretch.

To get to 1 to 4, we add 3. That means we will be moving the graph up 3 units.

Answer:

The sign on the 'x' changes, this implies a reflection.

g(x) = -f(x) = -(x+1) = -x -1

Now apply a vertical translation 'up 5' to f(x)

g(x) = -f(x) + 5 = (-x-1) +5 = -x +4

The solution of the given equalities is intersection of shaded region

To find the solution of the system of inequalities:

1) y < - (1/3)x + 1

2) y > 2|x - 1|

We can analyze each inequality separately and then find the intersection of their solutions.

1) For the inequality y < - (1/3)x + 1:

We can start by graphing the line y = - (1/3)x + 1. Since it is a strict inequality, we should use a dashed line to represent it.

Next, we need to determine which side of the line to shade to satisfy the inequality. Since y is less than the expression on the right side of the inequality, we shade the region below the line.

2) For the inequality y > 2|x - 1|:

First, let's consider the absolute value term |x - 1|. This term represents the distance between x and 1 on the number line. We can rewrite the inequality as two separate cases:

a) When x - 1 ≥ 0 (x ≥ 1), we have:

  y > 2(x - 1)

  y > 2x - 2

  We can graph the line y = 2x - 2. Since it is a strict inequality, we use a dashed line.

b) When x - 1 < 0 (x < 1), we have:

  y > 2(-(x - 1))

  y > -2x + 2

  We graph the line y = -2x + 2. Again, it is a strict inequality, so we use a dashed line.

For both cases, we shade the region above the respective lines to satisfy the inequalities.

Now, we need to find the intersection of the shaded regions from both inequalities.

The Remainder Theorem states that if a polynomial f(x) is divided by x - a, then the remainder of the division is equal to f(a). In other words, if we divide a polynomial by x - a, the value of the polynomial at x = a is equal to the remainder.

Using the Remainder Theorem, we can find P(a) for the polynomial f(x) = x^3 - 2x^2 - 3x + 6 when a = 2:

First, we need to create a polynomial that is equivalent to f(x) when divided by x - a. This is done by performing synthetic division, using a as the divisor:

2 | 1 -2 -3 6

2 0 -6

1 0 -3 0

The result of the synthetic division is the polynomial 1x^2 + 0x - 3 with a remainder of 0. This means that f(x) can be expressed as:

f(x) = (x - 2)(x^2 + 0x - 3)

We can now use the Remainder Theorem to find P(a) for f(x) when a = 2. This means that we need to evaluate the polynomial x^2 + 0x - 3 at x = 2:

P(2) = 2^2 + 0(2) - 3 = 1

Therefore, P(2) = 1.

The result P(2) means that when we divide the polynomial f(x) = x^3 - 2x^2 - 3x + 6 by x - 2, the remainder is 1.

Answer:

The linear equation is y = 450 - 30 x, where y is the number of pages

Lourdes has left to read after x days

Step-by-step explanation:

Each day, Lourdes reads 30 pages of a 450-page book

- We need to write a linear equation to represent the number of pages

 Lourdes has left to read after x days

∵ Lourdes reads 30 pages each day

∵ Lourdes will read for x days

∴ The number of pages Lourdes will read in x day = 30 x

- The left pages will be the difference between the total pages of the

 book and the pages Lourdes read

∵ The book has 450 pages

∵ Loured will read 30 x in x days

∴ The number of pages left = 450 - 30 x

- Assume that y represents the number of pages Lourdes has left

 to read after x days

∴ y = 450 - 30 x

The linear equation is y = 450 - 30 x, where y is the number of

pages Lourdes has left to read after x days

To find the expected number of times Joan rolls a 3, we use the formula for mean of a binomial distribution.

The correct option is, option (C) 6.

The probability of rolling a number 3 on any given roll is 1/4

If Joan rolls the die 20 times, the number of times she rolls a 3 will follow a binomial distribution with n = 20 (number of trials) and p = 1/4 (probability of success).

The formula for the probability mass function of a binomial distribution is:

P(X=k) = (n choose k) * p^k * (1-p)^(n-k)

where X is the random variable representing the number of successes (the number of times Joan rolls a 3), k is the number of successes, n is the number of trials, p is the probability of success, and (n choose k) is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Using this formula, we can calculate the probability of rolling a 3 exactly k times out of 20 rolls:

P(X=k) = (20 choose k) * (1/4)^k * (3/4)^(20-k)

To find the expected number of times Joan rolls a 3, we can use the formula for the mean of a binomial distribution:

E(X) = n * p

In this case, E(X) = 20 * 1/4 = 5

Therefore, the expected number of times Joan rolls a 3 is 5.

Since the possible answers are integers, the closest answer to 5 is 6. Therefore, the answer is (C) 6.

The body axis roll rate is 1.102 rad/s, the body axis pitch rate is -3.647 rad/s, and the body axis yaw rate is 0.079 rad/s

To find the body axis roll, pitch, and yaw rates using kinematic equations, we need to use the following equations:

Body axis roll rate (p) = (Ixx * L + (Izz - Iyy) * Q * R) / Ixx

Body axis pitch rate (q) = (Iyy * M + (Ixx - Izz) * P * R) / Iyy

Body axis yaw rate (r) = (Izz * N + (Iyy - Ixx) * P * Q) / Izz

where:

p, q, and r are the roll, pitch, and yaw rates in radians per second, respectively

L, M, and N are the moments about the body axes in Newton meters

P, Q, and R are the angular velocities about the body axes in radians per second

Ixx, Iyy, and Izz are the moments of inertia about the body axes in kilogram meters squared

To convert the given values in degrees per second to radians per second, we need to multiply them by pi/180.

Using the given values, we have:

omwphi = 100 deg/s = 100 * pi/180 rad/s = 1.745 rad/s

phi = 45 deg/s = 45 * pi/180 rad/s = 0.785 rad/s

psi = 10 deg/s = 10 * pi/180 rad/s = 0.175 rad/s

psi = 360 deg/s = 360 * pi/180 rad/s = 6.283 rad/s

theta = 10 deg/s = 10 * pi/180 rad/s = 0.175 rad/s

theta = 5 deg/s = 5 * pi/180 rad/s = 0.087 rad/s

Assuming the moments of inertia about the body axes are known, we can use the above equations to calculate the body axis roll, pitch, and yaw rates.

For example, let's say the moments of inertia about the body axes are:

Ixx = 100 kg \(m^2\)

Iyy = 200 kg  \(m^2\)

Izz = 300 kg  \(m^2\)

Using these values and the given angular velocities, we can calculate the body axis rates as follows:

Body axis roll rate (p) = (Ixx * L + (Izz - Iyy) * Q * R) / Ixx

= (100 * 0 + (300 - 200) * 0.175 * 6.283) / 100

= 1.102 rad/s

Body axis pitch rate (q) = (Iyy * M + (Ixx - Izz) * P * R) / Iyy

= (200 * 0 + (100 - 300) * 1.745 * 6.283) / 200

= -3.647 rad/s

Body axis yaw rate (r) = (Izz * N + (Iyy - Ixx) * P * Q) / Izz

= (300 * 0.087 + (200 - 100) * 1.745 * 0.175) / 300

= 0.079 rad/s

Therefore, the body axis roll rate is 1.102 rad/s, the body axis pitch rate is -3.647 rad/s, and the body axis yaw rate is 0.079 rad/s

We know that:

- stack of mail consists of 8 bills, 10 letters, and 6 advertisements.

- One piece of mail is drawn at random and put aside. Then a second piece of mail is drawn.

And we must find P (both are letters)

STEP BY STEP EXPLANATION:

To find the probability, we need to know that we have two events. First, when one piece of mail is drawn at random and put aside and, second, when a second piece of mail is drawn.

These two events are dependent. If A and B are dependent events, P(A and B) = P(A) • P(B after A) where P(B after A) is the probability that B occurs after A has occurred.

So, first

- Probability of A (the first piece is letter)

- Probability of B after A

Since A already occurred and one piece of the mail was drawn (a letter), now in total we would have 9 letter and 23 total pieces

Finally, replacing in the initial formula

Finally, the probability would be 0.1630

The discriminant can be positive, zero, or negative, and this determines how many solutions there are to the given quadratic equation. A positive discriminant indicates that the quadratic has two distinct real number solutions. A discriminant of zero indicates that the quadratic has a repeated real number solution.

Step-by-step explanation:

The discriminant of the quadratic equation g is negative.

In algebra, the discriminant of a quadratic equation plays a crucial role in determining the nature of its roots. For a quadratic equation of the form ax² + bx + c = 0, the discriminant is given by Δ = b² - 4ac. Depending on whether the discriminant is positive, zero, or negative, we can determine the types of roots the equation possesses.

When the discriminant is negative, it implies that the quadratic equation has no real roots. In this case, the graph of the quadratic equation does not intersect the x-axis at all, indicating that it has complex roots. These complex roots are a pair of complex conjugates of the form (p + qi) and (p - qi), where p and q are real numbers and i is the imaginary unit (√(-1)).

The rate at which the wage earners and rural households should save is 21%.

Given that:

Depreciation (δ) = 0.03

Capital output ratio (c) = 3

Profit share of income (π/Y) = 0.5

Savings out of capital income (sπ) = 25% = 0.25

We know that the modified Harrod-Domar growth model is given as:

c(g+δ) = (sπ - sW)(Yπ) + sW

We can rearrange the above equation to find the value of savings out of wage income as follows:

sW = c(g+δ - sπ(Yπ))/ (sπ - π/Y)

Plugging in the given values:

sW = 3(0.04 + 0.03 - 0.25(0.5))/ (0.25 - 0.5)

On solving the above equation, we get:

sW = 0.21 or 21%

Answer:

x = 45°

y = 90°

Step-by-step explanation:

    The 135° is on a line, so 180° - 135° = 45°

Since this is an isosceles triangle, x will be equal to 45° as well.

    The sum of a triangle's angles is 180°, so if we add them all together and subtract from 180° we will get our y.

180° - (45 + 45) = y

180° - 90° = y

90° = y

(a triangle can be both an isosceles and a right-triangle!)

After solving both the system of equations, we have the value of x as 4 and -4.

In this question, we have been given two equations.

y = 3x

y = x² + 3x - 16

We can substitute the value of y in first equation with the value of y in second equation and our new equation will be:

x² + 3x - 16 = 3x

Now, we will solve it.

x² + 3x - 16 = 3x

x² - 16 = 3x - 3x

x² - 16 = 0

After factorizing the number, we will have:

(x + 4) ( x- 4) = 0

Putting each equation equal to zero

x - 4 = 0

x = 4

x + 4 = 0
