To find f(x)/g(x), we factor both f(x) and g(x), and then simplify by canceling common terms. The simplified result is 2x + 3 / x + 2.

To find the quotient of two functions, f(x) and g(x), we divide the first function by the second. In this case, we have f(x) = 2x² - x - 6 and g(x) = x² - 4. The process involves the following steps:

Write the division of the two functions: f(x)/g(x).Simplify the expressions, if possible, by factoring and reducing them.

We start by factoring both f(x) and g(x):

f(x) = (2x + 3)(x - 2)
g(x) = (x + 2)(x - 2)

Now we divide f(x) by g(x):

f(x)/g(x) = ((2x + 3)(x - 2)) / ((x + 2)(x - 2))

Notice that the term (x - 2) is common in both the numerator and the denominator, so we can reduce the expression by canceling out the common term, resulting in:

f(x)/g(x) = (2x + 3) / (x + 2)

The correct result is the second option: 2x + 3 / x + 2.

Am I able to evaluate sin(cos^1(7/11)) without a calculator? If yes, how? ...?

Answers

Final answer:

Yes, you can evaluate sin(cos^-1(7/11)) without a calculator. The result can be simplified to √(72/121).

Explanation:

Yes, you can evaluate sin(cos-1(7/11)) without a calculator. Let's break it down step by step:

cos-1(7/11) represents the inverse cosine of 7/11. Inverse cosine is the angle whose cosine is equal to the given value. So, cos-1(7/11) is the angle whose cosine is 7/11.To evaluate sin(cos-1(7/11)), we need to find the sine of the angle we found in the previous step.Since we know that sin2(θ) + cos2(θ) = 1, we can use this relationship to find sin(θ) when we know cos(θ).Let's assume the angle we found in step 1 is θ. We know that cos(θ) = 7/11, so we can substitute this value into the equation sin2(θ) + (7/11)2 = 1 and solve for sin(θ).By solving the equation, we find that sin(θ) = √(1 - (7/11)2).Finally, we can simplify the expression sin(θ) = √(1 - (49/121)) or sin(θ) = √(72/121).

Therefore, sin(cos-1(7/11)) can be evaluated as √(72/121).

Rate of Change , you are given the dollar value of a product in 2004 and the rate at which the value of the product is expected to change during the next 5 years. Write a linear equation that gives the dollar value (v) of the product in terms of the year
(Let t=0 represent 2000.)

2004 value= $156 with $4.50 increase per year
...?

Answers

when t=4, v = 156the equation of linear liney = mx+bm=slopeb = y-intercept or initial valueapply it to this problemv = 4.5t + bto solve for b, use given info (v=156 when t=4)156 = 4.5(4) + bb = 156 - 4.5(4)b = 156 - 18b = 138
Linear equation:v = 4.5t +138this means the product had value of $138 in 2000

Answer:

The linear equation is v = 4.5t +138

The product had value of $138 in 2000.

Step-by-step explanation:

In 2004, dollar value(v) = $156 and rate of change (m) = $4.50

The linear equation is in the form of y = mx + b, where "m" is slope or rate of change, b is the y-intercept.

We can rewrite the equation as v = m(t) + b.

Now let's find the value of b, when t = 4, m = 4.5, v = 156

156 = 4.5(4) + b

b = 156 - 4.5(4)

b = 156 - 18

b = 138

So, the linear equation is v = 4.5t +138

When t=0, the dollar value (v) = 4.5(0) + 138

v = $138

So, the product had value of $138 in 2000

what is the correct expansion of the binomial (x+y)^5

This is the answer to your problem.

Answer: The correct expansion is,

[tex]x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5[/tex]

Step-by-step explanation:

Since, by the binomial expansion,

[tex](p+q)^n=\sum_{r=0}^{n} ^nC_r (p)^{n-r}(q)^r[/tex]

Where,

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

Here, p = x and q = y and n = 5,

By substituting values,

[tex](x+y)^5=\sum_{r=0}^{5} ^5C_r (x)^{n-r}(y)^r[/tex]

[tex] =^5C_0(x)^{5-0}(y)^0+^5C_1 (x)^{5-1}(y)^1+^5C_2 (x)^{5-2}(y)^2+^5C_3 (x)^{5-3}(y)^3+^5C_4 (x)^{5-4}(y)^4+^5C_5(x)^{5-5}(y)^{5}[/tex]

[tex]=x^5+\frac{5\times 4!}{4!}x^4y^1+\frac{5\times 4\times 3!}{3!2!}x^3y^2+\frac{5\times 4\times 3!}{2!3!}x^2y^3+\frac{5\times 4!}{4!}x^1y^4+\frac{5!}{5!}y^5[/tex]

mx+4y=3t, Solve for the value of x

Answers

The answer is x = (3t - 4y)/m

mx + 4y = 3t
__________
Distract 4y from both sides of the equation:
mx = 3t - 4y
__________
Divide both sides of the equation by m:
x = (3t - 4y)/m
Final answer:

To solve mx+4y=3t for x, subtract 4y from both sides to isolate the x term, giving mx = 3t - 4y. Then, divide both sides by m to solve for x, resulting in x = (3t - 4y) / m.

Explanation:

To solve the equation mx+4y=3t for the value of x, follow these steps:

First, isolate the x term by moving the 4y to the other side of the equation. This gives us:mx = 3t - 4yNext, divide both sides of the equation by m to solve for x:x = (3t - 4y) / m

You can now plug in the known values for y, t, and m to find the value of x.

Enter the slope-intercept equation of the line that has slope -6 and y-intercept (0, 2).

Answers

In y = mx + b form, the m is ur slope and the b is ur y int.

so ur equation in slope intercept form with a slope of -6 and a y int of 2 is :
y = -6x + 2

The slope-intercept form of equation of the line that has slope -6 and y-intercept (0, 2) is y=-6x+2.

What is the slope intercept form?

The slope intercept form of a straight line is one of the most common forms used to represent the equation of a line. The slope intercept formula can be used to find the equation of a line when given the slope of the straight line and the y-intercept.

The standard form of the slope intercept form is y=mx+c.

Given that, the line that has slope -6 and y-intercept (0, 2).

The y-intercept is the point where a graph crosses the y-axis. In other words, it is the value of y when x=0.

Here, m=-6 and c=2

Substitute m=-6 and c=2 in y=mx+c, we get

y=-6x+2

Therefore, the slope-intercept form of equation of the line that has slope -6 and y-intercept (0, 2) is y=-6x+2.
