To find the common roots between two functions, we need to find the roots (or solutions) of each function individually and then identify the shared solutions.

For the function f(x) = x^2 + x - 6, we can find the roots by setting the function equal to zero and solving for x:

x^2 + x - 6 = 0

To factorize this quadratic equation, we need to find two numbers that multiply to -6 and add up to 1 (the coefficient of x). The numbers that satisfy these conditions are 3 and -2:

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

Setting each factor equal to zero:

x + 3 = 0 or x - 2 = 0

Solving for x in each equation:

x = -3 or x = 2

Therefore, the function f(x) = x^2 + x - 6 has two roots: x = -3 and x = 2.

To find the common roots between this function and another function, we would need to know the second function. If you provide the second function, I can help determine if there are any shared roots.

So, the rate at which the area of the circular surface of the cookie dough is increasing with respect to time is 80π mm^2/min and the rate at which the height is decreasing with respect to time is  -2 mm/min.

Part A: The area of the circular surface of the cookie dough is given by A = πr^2, where r is the radius of the dough. The rate at which the area is changing with respect to time is given by dA/dt = 2πr*dr/dt. At time t, the radius is 20 mm and the rate at which it is increasing is 2 mm/min. Therefore, the rate at which the area of the circular surface of the cookie dough is increasing with respect to time is dA/dt = 2π(20 mm)(2 mm/min) = 80π mm^2/min.

Part B: The height of the dough is given by h, and the rate at which the height is decreasing with respect to time is given by dh/dt. Since the dough is retaining its cylindrical shape, the decrease in the height of the dough is exactly the opposite of the increase in the radius. At time t, the rate at which the radius is increasing is 2 mm/min, so the rate at which the height is decreasing with respect to time is dh/dt = -2 mm/min.

Answer:

any number

Step-by-step explanation:

Using simple interest, we have that:

The amount of money accrued in simple interest, after t years, is given by:

\(A(t) = Pit\)

In which:

In this problem, there is an interest rate of 8%, hence \(i = 0.08\).

The down payment is of 5%, hence, the principal is 95% of the price, that is, \(P = 0.95(100000) = 95000\)

Then, for the 20 year option, \(t = 20\), and:

\(A(t) = Pit = 95000(0.08)(20) = 152000\)

The amount of interest paid for the 20 year option is $152,000.

For the 30 year option, \(t = 30\), and:

\(A(t) = Pit = 95000(0.08)(30) = 228000\)

The amount of interest paid for the 30 year option is $228,000.

228000 - 152000 = 76000

The buyer saves $76,000 in interest with the 20 year option.

The equivalenet expression is 54\(n^{-11}\)

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

To simplify the given expression, we need to apply the power of a power rule, which states that to raise a power to another power, we need to multiply the exponents.

Starting with:

(\(6n^-5\))(\(3n^-3\))²

We can simplify as follows:

(\(6n^-5\))(\(9n^-6\))

Now, we can use the product of powers rule, which states that when multiplying two powers with the same base, we add their exponents.

Therefore:

6 x 9 = 54

\(n^-5 * n^-6 = n^-11\)

So the simplified expression is:

\(54n^-11\)

Therefore, the expression \((6n^-5)(3n^-3)^2\) is equivalent to \(54n^-11.\)

gradient of the line = -5/9

general equation for all straight lines: y = mx + c

Answer:

(a) He would need 76 feet of fencing

(b) Kevin should buy the packaged box of 90 feet of fencing for $950.

(c) How much does he save?

For every 1 feet of packaged fencing Kevin buys, he saves $1.94 naira.

Step-by-step explanation:

(a) At the outside edge of the pool is a protective fence. How many feet of fencing would be needed to surround the pool area?

From the question, we are told that the swimming pool measures:

14-1/2 feet wide and 23-1/2 feet long.

Perimeter of a fence = 2(L + W)

= 2( 14-1/2 + 23-1/2)feet

= 76 feet

This means he need 76 feet of fencing.

(b) Kevin discovers that he can buy a packaged box of 90 feet of fencing for $950 or he can buy cut-to-order fencing that costs $12.40 per foot. Which type of fencing should he buy?

If : For cut to order fencing

1 foot = $12.40

76 feet =

Cross Multiply

= 76feet × $12.40/1 foot

= $942.4

This means that the cut to order fencing would cost him $942.40

The packaged box of fencing cost $950 for 90 feet of fencing. This is cheaper than the cut to order fencing and he would have extra feet of fencing(14 feet) .

Therefore, Kevin should buy the packaged box of 90 feet of fencing for $950.

How much money does he save?

For the cut to order box

1 feet = $12.40

For the packaged fence,

90 feet = $950

1 feet = x

= 950/90

= $10.555555556

≈ $10.56

Hence, 1 feet of packaged fence = $10.56

Subtracting $10.56 from $12.40

= $12.40 - $10.56

=$ 1.94

Therefore, for every 1 feet of packaged fencing Kevin buys, he saves $1.94 naira.

This means:

1 feet (packaged fence) = $10.56

76 feet = x

= 76 × $10.56

= $802.56

The probability that the sample proportion will be at least 2 percent more than the population proportion is 40%.

The population mean's likelihood to differ from a sample mean is indicated by the standard error of the mean, or simply standard error. It reveals how much the sample mean would change if a study were to be repeated with fresh samples drawn from a single population.

You may determine the accuracy of the comparison between the mean of any given sample from a population and the actual population mean by looking at the standard error. Any given mean is more likely to be an inaccurate depiction of the genuine population mean as the standard error rises, or as the means grow more dispersed.

Given:

p = 0.75, the population proportion

n = 135, the sample size

Now, Standard error

= √p(1- p)/n

= √0.75 x 0.25 / 135

= √0.1875/135

= 0.0372

Now, 2% of p = 0.02 x 0.75 = 0.015

Now, the confidence interval

z x SE= 0.015

z = 0.015/0.0372

z= 0.4032

Explanation:

Segment AW bisects angle CAD.

This leads to the smaller pieces (angles CAW and DAW) to be equal to one another. Both are 20 degrees each. That totals to 20+20 = 40 degrees.

Therefore, angle CAD = 40 degrees.

The supplement of this is angle DAX

(angle CAD) + (angle DAX) = 180

angle DAX = 180 - (angle CAD)

angle DAX = 180 - 40

The triangle for which angle a =30\degree, angle b=45\degree, and a=20, side a ≈ 20, side b ≈ 28.284, and side c ≈ 38.636

Two angles (a and b) and one side (a) are provided for us to solve the triangle. Let's call the side across from angle a side A, the side across from angle b side B, and the side across from the final angle (angle c) side C.

Here, it is given that,

angle a = 30 degrees

angle b = 45 degrees

side a = 20

angle c = 180 - (angle a + angle b)

angle c = 180 - (30 + 45)

angle c = 180 - 75

angle c = 105 degrees

We know that, a/sin(A) = b/sin(B) = c/sin(C)

a/sin(A) = b/sin(B) = c/sin(C)

20/sin(30) = b/sin(45) = c/sin(105)

b/sin(45) = 20/sin(30)

b = (sin(45) * 20) / sin(30)

b ≈ (0.7071 * 20) / 0.5

b ≈ 14.142 / 0.5

b ≈ 28.284

Now,

c/sin(105) = 20/sin(30)

c = (sin(105) * 20) / sin(30)

c ≈ (0.9659 * 20) / 0.5

c ≈ 19.318 / 0.5

c ≈ 38.636

Thus, side a ≈ 20, side b ≈ 28.284, and side c ≈ 38.636.
