Simplify the expression.Can you help me with this one. I'm stuck at 12^x4 - 15x^2

The answer for this process of long division is, therefore:

To find the result for this long division, we needed to divide the first term of the polynomial by the x in the divisor. Then, if we see the first graph, we have:

Then, we need to multiply this term by the divisor (x - 3), and then, subtract the result from the first two terms of the dividend. We can see as follows:

This will be his initial investment. The amount for 8% will be 84000, and the amount for 12% will be 204000.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the

value of the variable x is 7.

let x = the money invested at 8%

y = the money invested at 12%

an actor invests some money at 8% and 36,000 more than four times the amount at 12%

x = 36000 + 2y

total annual interest earned from the investment is 26400

0.08*x + 0.12*y = 26400

by solving the system of equations

x = 36000 + 2y

0.08*x + 0.12*y = 26400

solving the equations,

0.08(36000+2y)+0.12y=26400

2880+0.16y+0.12y=26400

y=84000

x=204000

The amount for 8% will be 84000, and the amount for 12% will be 204000.

The absolute value inequality is given by | x-130745 | > 10000

and the possibility of Car B is  x < 120745  or  x > 140745

What is absolute value inequality?

Absolute value inequality are inequalities in algebra that involve algebraic expressions with absolute value symbols and inequality symbols. In simple words, we can say that an absolute value inequality is an inequality with an absolute value symbol in it. It can be solved using two methods of either the number line or the formulas.

x = price of car B

x-130745 = difference in price from car A to car B

If x is the larger price, then x-130745 will be positive. If x is the smaller price, then x-130745 is negative.

In short,

x-130745 > 0 when x > 130745

x-130745 < 0 when x < 130745

Using absolute value will give us

|x-130745| = positive difference in price

The result of an absolute value is never negative

We write the |x-130745| > 10000 to indicate that the difference in price is more than 10000 dollar

 | x-130645 | > 10000

Part b.

We'll use the idea that if |x| > k, then x < -k or x > k

to get the following

|x-130745| > 10000

x-130745 < -10000 or x-130745 > 10000

x < -10000+130745  or  x > 10000+130745

x < 120745  or  x > 140745

Car B has a price less than $120,745

OR

Car B has a price greater than $140,745

So basically anything that is not between 120745 and 140745. The price has to be positive of course.

P (B U C) is 0.1675 when B and C are independent and P (B U C) is 0 when B and C are mutually exclusive.

An Independent Event is defined as if the outcome of one event has no bearing on the outcome of the other, the two events are said to be independent events. Or, we may say that an event is considered independent if it does not affect the probability of another event. Probability-independent events mirror actual occurrences.

Let B and C be two events such that P(B) = 0.25 and P(C) = 0.67.

To determine P (B U C),

Given that B and C are independent.

Since B and C are independent events, we can just multiply the probabilities together, 0.25 × 0.67 = 0.1675

To determine P (B U C),

Given that B and C are mutually exclusive.

Since B and C cannot both occur at the same moment by definition because they are mutually exclusive, the answer is 0.

Therefore, P (B U C) is 0.1675 when B and C are independent and P (B U C) is 0 when B and C are mutually exclusive.

The quadratic equation with roots -7, 3/4 in standard form is

4x² + 25x - 21 = 0.

A quadratic equation is an algebraic equation of degree two and has exactly two roots real or imaginary or complex.

We know the roots of a quadratic equation are also factors of a quadratic equation.

If x = a and x = b are two roots of a quadratic equation then x - a = 0 and

x - b = 0 are the factors of a quadratic equation that can be formed by multiplying the two factors (x - a)(x - b) = 0.

Given that -7 and 3/4 are the roots.

∴ { x - (-7)}{ x - 3/4) = 0.

(x + 7)(x - 3/4) = 0.

x² + 7x -(3/4)x - 21/4 = 0.

x² + (25/4)x - 21/4 = 0.

4x² + 25x - 21 = 0.

Hello!

First, let me explain the difference between discrete and continuous.

Discrete: only some numbers of the interval are on the input. For example, in the interval 1 - 10, consider only the integers.

Continuous: all the numbers of the interval are on the input. For example: in the interval 1 - 10, all values are considered (integers and decimals).

Knowing it, let's analyze your exercise:

The function D = 25 + 0.3x represents the daily rental charge D (in dollars) for x miles driven.

We can represent miles as integers and also decimals, right?

• 2 miles

• 5.750 miles

So, it means that all values can be considered.

So, this is a continuous domain.

45 represents the slope while -900 is the y-intercept of the function

Here, we want to write the slope and y-intercept of the function that represents Patrick's elevation during his climbing

From the question, we are told that he averaged an elevation of 45 meters per hour

What the slope basically does is to measure a rate of change. As we can see from here, the change represents a rate and thus, we have this as our slope

To get the y-intercept of the function, we can see this as a distance of -900 meters

The reason for this is that we can see the summit of the mountain as 0 m

So we can represent the equation as;

The height is 9.875 feet from which the goalkeeper catches the ball.

The player kicks soccer from a height of 2 feet

x = 0 and y = 2

Maximum height of 20 feet after traveling 40 feet

x = 40, y = 20

So let y = a(x - 40)² + 20  ( the path of parabola)

Since x = 0 , y = 2

So, 2 = a(0 - 40)² + 20

2 = 1600a + 20

-18 = 1600a

a = - 9/800

Thus, y = -9/800(x - 40)² + 20

Since the soccer is caught by the goalkeeper 70 feet from where it was kicked

x = 70

So at this time,

y = -9/800 ( 70 - 40)² + 20

  = -9/800 × 900 + 20

  = - 81/8 + 20

  = 79/ 8

  = 9.875 feet

Therefore the height at which the goalkeeper catches the ball is 9.875 feet.

Where:

The equation for the velocity of the body in simple harmonic motion is found differentiating (1):

v = - ω · Δy · sin ωt      (2)

If we know that ω = 1, t = 2π / 3 and Δt = 5, then the velocity of the body is:

v = - 1 · 5 · sin (2π / 3)

v = - 5 · sin (2π / 3)

Many graduate schools require applicants to take a certain test. Those taking the test receive three scores:

a verbal reasoning score,

a quantitative reasoning score,

an analytical writing score.

Let average verbal reasoning score represent by v

Let average quantitative reasoning score represent by q

Let average analytical writing score represent by a

In 2013, the average quantitative reasoning score exceeded the average verbal reasoning score by 1.3 points

i.e.,

Average quantitative reasoning score - average verbal reasoning = 1.3

q - v = 1.3 ...(1)

The average verbal reasoning score exceeded the analytical writing score by 150.5 points.

i.e.,

Average Reasoning score - average analytical writing = 150.5

v - a = 150.5 ...(2)

The sum of the three average scores was 305.9.

i.e.,

v + q + a = 305.9 ...(3)

Simplify the equation (1), (2) and (3) to get the value of q,v and a;

Add equation (1) and (2)

(q-v) + (v-a) = 1.3 + 150.5

q + a = 151.8 ....(4)

Substitute the value of (q+a=151.8) in the equation (3);

v + q + a = 305.9

v + 151.8 = 305.9

v = 305.9 - 151.8

v = 154.1

Substitute the value of v = 154.1 in the equation (2);

v - a = 150.5

154.1 -a = 150.5

a = 154.1 - 150.5

a = 3.6

Now, substitute the value of a = 3.6 in the equation (4)

q + a = 151.8

q + 3.6 = 151.8

q = 151.8 - 3.6

q = 148.2

Answer :

The average verbal reasoning score was 154.1
