The coefficient of the term containing y^8 in the expansion of [(x/2)-4y]^9 is -126.

To find the coefficient of the term containing y^8, we can use the Binomial Theorem. According to the Binomial Theorem, the expansion of (a + b)^n can be written as:

(a + b)^n = C(n,0) * a^n * b^0 + C(n,1) * a^(n-1) * b^1 + C(n,2) * a^(n-2) * b^2 + ... + C(n,k) * a^(n-k) * b^k + ... + C(n,n) * a^0 * b^n

where C(n,k) is the binomial coefficient given by C(n,k) = n! / (k! * (n-k)!).

In our case, a = x/2 and b = -4y. Plugging these values into the formula, we have:

[(x/2)-4y]^9 = C(9,0) * (x/2)^9 * (-4y)^0 + C(9,1) * (x/2)^8 * (-4y)^1 + C(9,2) * (x/2)^7 * (-4y)^2 + ... + C(9,8) * (x/2)^(9-8) * (-4y)^8 + C(9,9) * (x/2)^0 * (-4y)^9

The term containing y^8 is C(9,8) * (x/2)^(9-8) * (-4y)^8 = C(9,8) * (x/2) * (-4y)^8.

The binomial coefficient C(9,8) is equal to 9, and the term (x/2) * (-4y)^8 simplifies to (-4)^8 * (x/2) * y^8 = 65536 * (x/2) * y^8.

Therefore, the coefficient of the term containing y^8 is 65536 * (x/2) = 32768x.

The area of the region between line y =3x -6 and line y=-2x+8 and

the x-axis with the help of integration will be 2.88 sq units.

What exactly is integration?

The process of computing an integral is known as integration. Mathematicians utilise integrals to compute a variety of useful quantities such as areas, volumes, displacement, and so on. When we talk about integrals, we usually imply definite integrals. Antiderivatives are represented by indefinite integrals. Integration, along with differentiation, is one of the two major calculus concepts in mathematics (which measure the rate of change of any function with respect to its variables).

Integral Fundamental

A definite integral is one that has both upper and lower bounds. For X to lie, only a true line may be utilised. The Definite Integral is also known as a Riemann Integral.

From a to b, use ∫f(x)dx

indefinite integral

Integrals are defined without upper and lower limits. It looks like this:

A indefinite Integral is written as:

∫f(x)dx = F(x) + C

Where C might be any constant and the function f(x) is referred to as the integrand.

Now,

As given in image

Area of the region will be  =∫3x-6 dx from x=2 to 2.8 +∫-2x+8 from x=2.8 to 4.

=(3x²/2-6x) from x=2 to 2.8 + (-2x²/2+8x)  from x=2.8 to 4.

=3*0.8*0.8/2-6*0.8-2*1.2*1.2+8*1.2

=2.88 sq units.

Hence,

           The area of the region between line y =3x -6 and line y=-2x+8 and the x-axis with the help of integration will be 2.88 sq units.

To construct a 98% confidence interval for B₁, we can use the t-distribution since the sample size is small (n = 12).

Given the sample mean (B₁ = 46), sample standard deviation (s = 5.7), and sum of squares (SSzz = 57), we can calculate the confidence interval.

The formula for a confidence interval is:

Confidence Interval = Sample Mean ± (Critical Value * Standard Error)

For a 98% confidence level and n = 12, the critical value is approximately 2.681 (obtained from a t-distribution table).

The standard error is calculated as the sample standard deviation divided by the square root of the sample size (s / √n).

Plugging in the values:

Standard Error = 5.7 / √12 ≈ 1.647

Confidence Interval = 46 ± (2.681 * 1.647)

Therefore, the 98% confidence interval for B₁ is approximately (42.21, 49.79).

In conclusion, we can be 98% confident that the true value of B₁ falls within the range of 42.21 to 49.79 based on the given sample data.

Step-by-step explanation:

a. The medium coffee is the best value for money.

b. The percentage profit is 40%

c The cafe is likely doing this because they know that many people will choose the small coffee because it is the cheapest option.

a) The cost per 100 ml of coffee is:

2.40 / 250 = 0.96p

The cost per 100 ml of coffee for the medium and large sizes is:

2.70 / 330 = 0.82p

3.00 / 500 = 0.60p

Therefore, the medium coffee is the best value for money.

b) The profit on a small coffee is:

2.40 - (0.96 x 250) = 0.96p

The percentage profit is:

(0.96 / 2.40) x 100 = 40%

c) The large coffee is twice the size of the small coffee, but the difference in price is only 60p. This is because the cafe is making a larger profit on the small coffee. The cafe is likely doing this because they know that many people will choose the small coffee because it is the cheapest option.

The statement that It is sufficient to test an analogy by asking what are its relevant similarities is false.

Analogy refers to the process of comparison of two or more items such that it explains some idea, or classification or familiarity and representativeness. Studying the analogies helps in enhancing, strengthening and reinforcing the skills in areas such as reading comprehension, homophones, deductive reasoning and logic.

Testing an analogy only by relevant similarities will produce partial results which might not be suitable to fully explain the reason.

The weight of the astronaut with gear on the moon is 80 pounds.

The pull of gravity is different on Earth than on the Moon as gravity depends on factors such as the mass of the celestial body, the radius of the celestial body, and the density of the celestial body.

The pull of gravity on Earth = 10 m/s²

Thus, Given:

Weight of object on Earth: 25 pounds

Weight is described as the product of mass and the acceleration due to gravity

Thus, 25 = 10 * mass

mass = 2.5 unit

Weight of the object on the Moon: 4 pounds

4 = 2.5 * acceleration due to gravity on the moon

Acceleration due to gravity on the moon = 1.6 m/s²

Weight of astronaut with gear on earth = 500 pounds

500 = mass * 10

mass = 50 units

Weight of astronaut with gear on earth = 50 * 1.6

Answer:

The solution is -22

Step-by-step explanation:

The solution of an equation is the value of the variable of the equation

∵ -(4x - 3) = -7(9 + x)

→ Simplify each side

∵ -(4x) - -(3) = -7(9) + -7(x)

∴ (-4x) - (-3) = -63 + (-7x)

→ Remember (-)(-) = (+) and (-)(+) = (-)

∴ -4x + 3 = -63 - 7x

→ Add 7x to both sides

∴ -4x + 7x + 3 = -63 - 7x + 7x

∴ 3x + 3 = -63

→ Subtract 3 from both sides

∵ 3x + 3 - 3 = -63 - 3

∴ 3x = -66

→ Divide both sides by 3

∴ x = -22

∴ The solution is -22

The value of m in the image below which shows two parallel lines that are crossed by a transversal is: m = 102.

Examining the image attached below, we have a transversal, line d, which crossed the two parallel lines, lines e and f, to form same-side interior angles, 78° and m°.

These two angles are said to be supplementary to each other based on the same-side interior angles theorem.

Therefore:

78 + m = 180

Subtract 78 from both sides:

78 + m - 78 = 180 - 78

m = 102°

Therefore, the value of m is: m = 102.

The quadratic equation with roots 2 + 5i and 2 - 5i is: x² - 4x - 21 = 0.The quadratic equation with roots 3 + 4i and 3 - 4i is:x² - 6x - 7 = 0

The sum of the roots of the quadratic equation ax² + bx + c = 0 is -b/a and the product of the roots is c/a.

If a = 1, then the sum of the roots is -b and the product of the roots is c.

Given that the roots are 2 + 5i and 2 - 5i, the sum of the roots is 2 + 5i + 2 - 5i = 4.

The product of the roots is (2 + 5i)(2 - 5i) = 4 - 25 = -21.

Therefore, the quadratic equation with roots 2 + 5i and 2 - 5i is: x² - 4x - 21 = 0

Let the roots be 3 + 4i and 3 - 4i.

The sum of the roots is 3 + 4i + 3 - 4i = 6.

The product of the roots is (3 + 4i)(3 - 4i) = 9 - 16 = -7.

Therefore, the quadratic equation with roots 3 + 4i and 3 - 4i is:x² - 6x - 7 = 0

I think the answer is 20

Step-by-step explanation:

to solve you take the number on the right, subtract it by one, then multiple the new number by the old one.

1-1=0x1=0

3-1=2x3=6

4-1=3x4=12

2-1=1x2=2

5-1=4x5=20

We will see that the pattern is defined by the function:

f(x) = (x - 1)*x

Such that:

f(5) = 20.

Here we have the relations:

1 = 0

3 = 6

4 = 12

2 = 2

5 = ?

We can think this as a function, actually:

f(1) = 0

f(3) = 6

f(4)  = 12

f(2) = 2

f(5) = ?

Now, one pattern that can be seen is that:

f(1) = (1 - 1)*1 = 0

f(2) = (2 - 1)*2 = 2

f(3) = (3 - 1)*3 = 6

And so on, so the function is actually:

f(x) = (x - 1)*x

Evaluating it in 5, we will see that:

f(5) = (5 - 1)*5 = 20
