A builder builds a brick wall that is 10m long and 1.5m high. The face of a brick is 20cm by 10cm. How many bricks will be needed to complete the wall?

Answer:

The answer is 28.8, When finding the Volume of a shape, you multiply all numbers.

Line with slope\($\mathrm{m}=\frac{3}{2}$\) and passing through \($(13,-8): \quad y=\frac{3}{2} x-\frac{55}{2}$\).

What is Line?

A line is an object in geometry that is indefinitely long and has neither breadth nor depth nor curvature. Since lines can exist in two, three, or higher dimensional environments, they are one-dimensional things. The term "line" may also be used to describe a line segment in daily life that contains two locations that serve as its endpoints.

Compute the line equation\($\mathbf{y}=\mathbf{m x}+\mathbf{b}$\) for slope \($m=\frac{3}{2}$\) and passing through (13,-8)

Compute the y intercept:\($\quad b=-\frac{55}{2}$\)

Construct the line equation y=m x+b where \(m=\frac{3}{2}$ and $b=-\frac{55}{2}$\)

\(y=\frac{3}{2} x-\frac{55}{2}$$\)

Another point on the line is (-9, 7). Ultimately, the choice of which point to use depends on the context or specific requirements of the problem you are solving.

To determine which point to use from the equation y - 7 = 3(x + 9), we need more information.

The equation provided represents a linear equation in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Without additional context or specific instructions, we can choose any point that satisfies the equation to use as a reference.

For example, if we let x = 0, we can solve the equation for y:

y - 7 = 3(0 + 9)

y - 7 = 3(9)

y - 7 = 27

y = 27 + 7

y = 34

So, one point on the line is (0, 34).

Alternatively, if we let x = -9, we can solve the equation for y:

y - 7 = 3(-9 + 9)

y - 7 = 3(0)

y - 7 = 0

y = 7

So, another point on the line is (-9, 7).

The electric current to flow through the resistors and complete the circuit by reaching its intended destination or powering a device.

In the analogy of a circuit with resistance, we can compare it to an obstacle race. Here's how we can relate the different elements:

Circuit: The entire obstacle race course represents the circuit itself. It includes all the components and paths that the participants will go through.

Obstacles: The obstacles in the race represent the resistors in the circuit. Just like resistors impede the flow of electrical current in a circuit, obstacles in the race impede the progress of the participants.

People/Participants: The people participating in the race represent the flow of electric current in the circuit. They are the "charge" moving through the circuit, encountering and overcoming obstacles (resistors) to reach the finish line.

The goal of the participants (people) is to navigate through the obstacles (resistors) and complete the race (circuit) by reaching the finish line.

Similarly, in an electrical circuit, the goal is for the electric current to flow through the resistors and complete the circuit by reaching its intended destination or powering a device.

If probability  each parent is heterozygous for both features, determine the likelihood that a child will only have cystic fibrosis or sickle-cell anaemia.

P(Sickle-cell Anemia)

= 0.25

P(Cystic Fibrosis)

= 0.25

P(Sickle-cell Anemia or Cystic Fibrosis) = P(Sickle-cell Anemia) + P(Cystic Fibrosis)

The likelihood that a child will have either cystic fibrosis or sickle-cell anaemia is 0.5 or 50%. This is because both parents are heterozygous for both features. This means that each parent has a 25% chance of passing on either one of the conditions to their child. The probability of having either one of the conditions is the sum of the individual probabilities, which is 0.25 + 0.25 = 0.5 or 50%.

By using the Conjugate Roots Theorem, the factored form of the polynomial is:

f(x) = (x + 6i)(x - 6i)(x - (3 + i√27)/2)(x - (3 - i√27)/2).

What is Conjugate Roots Theorem?

The Conjugate Roots Theorem is a theorem in algebra that states that if a polynomial function has a complex root of the form a + bi, where a and b are real numbers, then its conjugate a - bi is also a root of the polynomial.

Since −6i is a zero of the polynomial, then 6i is also a zero by the conjugate pairs theorem. Therefore, the factors are:

f(x) = (x - (-6i))(x - 6i)(x - r)(x - s)

where r and s are the remaining roots of the polynomial.

Using the fact that the coefficients of the polynomial are all integers, we can determine that r and s are the conjugate pair of complex numbers: r + si and r - si.

By Vieta's formulas, we know that:

the sum of the roots is -3/1 = -3

the product of the roots is 1944/1 = 1944

Therefore:

r + si + r - si - 12i = -3

(r + si)(r - si) = 1944/12 = 162

\(r^2 + s^2 = -3\)

From the first two equations, we get:

\(r^2 + s^2 + 2rsi = 162\)

2rsi = -12i

rs = -6

Solving for r and s, we can find:

\(r^2 + s^2 = -3\)

rs = -6

Multiplying the second equation by 4 and adding 12 to both sides, we get:

\(4r^2 - 12rs + 9s^2 = 12\)

\((2r - 3s)^2 = 12\)

Taking the square root of both sides, we get:

2r - 3s = ±2√3

Solving for r and s, we get:

r = (3s ± 2√3)/2

Substituting into the equation rs = -6, we can solve for s:

s = -6/r

Substituting into the equation \(r^2 + s^2 = -3\), we get:

\(r^2 + (-6/r)^2 = -3\)

\(r^4 + 36 = 3r^2\)

\(r^4 - 3r^2 + 36 = 0\)

This is a quadratic equation in \(r^2\). Solving for \(r^2\) using the quadratic formula, we get:

\(r^2\) = (3 ± i√27)/2

Therefore, the roots of the polynomial are:

x = -6i, 6i, (3 + i√27)/2, (3 - i√27)/2

Thus, the factored form of the polynomial is:

f(x) = (x + 6i)(x - 6i)(x - (3 + i√27)/2)(x - (3 - i√27)/2)

Answer:

1.32km (answer might differ slightly due to different values of speed of sound, in the range of 320 to 340 ms-1)

Step-by-step explanation:

Speed of lightning = 3 x 10^8 m/s (same as speed of light)

Speed of sound = 330 m/s (most common answer for speed of sound)

Let the time taken for lightning be T seconds

Time taken for thunder to reach her = (T + 4) seconds

Hence, an equation can be formed

Distance between lightning and her = Distance between thunder and her

Distance = Speed x Time

T(3x 10^8) = (T+4)(330)

((3 x 10^8) - 330)T = 4(330)

Solving, T = 4.40 x 10^-6

Hence,

Distance from storm = (4.40 x 10^-6)(3 x 10^8) metres

Using the scale factor given, the amount of fence, to the nearest foot, that they will have to purchase is: 297 feet.

Let P be the perimeter of your yard. We know that P = 339 feet.

Let k be the scale factor for your friend's yard. We know that the perimeter of your friend's yard is 7/8 times the perimeter of your yard, so the perimeter of your friend's yard is:

7/8 * P = 7/8 * 339 = 296.625 feet

Since your friend's yard is similar to yours, the ratio of corresponding sides is k. Since the perimeter is the sum of all sides, we can write:

k * P = 296.625

Solving for k, we get:

k = 296.625 / P = 296.625 / 339 = 0.875

So the scale factor for your friend's yard is 0.875.

Now we can use the scale factor to find the length of fence your friend will need to purchase. The length of fence for your yard is P, so the length of fence for your friend's yard is:

k * P = 0.875 * 339 = 296.625 feet

Therefore, your friend will need to purchase approximately 297 feet of fence.

Line equation => \( 2.1x + 9.9y - 9.2 = 0 \)

Required:

x-intercept and y-intercept of the line.

SOLUTION:

The x-intercept is the point where the line intercepts the x-axis. To find the x-intercept of the line for which the equation is given above, set y = 0 and solve for x.

\( 2.1x + 9.9(0) - 9.2 = 0 \)

\( 2.1x + 0 - 9.2 = 0 \)

\( 2.1x - 9.2 = 0 \)

\( 2.1x - 9.2 + 9.2 = 0 + 9.2 \)

\( 2.1x = 9.2 \)

\( \frac{2.1x}{2.1} = \frac{9.2}{2.1} \)

\( x = 4.4 \) (approximated)

The y-intercept is the point where the line intercepts the y-axis. At this point, x = 0. Set x = 0 and solve for y to find the y intercept.

\( 2.1(0) + 9.9y - 9.2 = 0 \)

\( 9.9y - 9.2 = 0 \)

\( 9.9y - 9.2 + 9.2 = 0 + 9.2 \)

\( 9.9y = 9.2 \)

\( y = \frac{9.2}{9.9} \)

\( y = 0.9 \) (approximated)

1a. The percentage total return is -19.56%

1b. The dividend yield is 2.42%.

1c. The capital gains yield is -21.98%.

2a. The arithmetic average annual return on large-company stocks in nominal terms is 14.5%.

2b. The arithmetic average annual return on large-company stocks in real terms is 9.67%.

3a. The real return on long-term government bonds is 3.195%

3b. The real return on long-term corporate bonds is 3.291%

In Financial accounting, the percentage total return (P) can be calculated by using this formula;

P = [(Ending price - Initial price) + Dividend] ÷ Initial price

P = [(71 - 91) + 2.20] ÷ 91

P = -0.1956 or -19.56%

1b. For the dividend yield, we have:

Dividend yield = Dividend ÷ Initial price

Dividend yield = 2.20 ÷ 91

Dividend yield = 0.0242 or 2.42%

1c. For capital gains yield, we have:

Capital gains yield = (Ending price - Initial price) ÷ Initial price

Capital gains yield = (71 - 91) ÷ 91

Capital gains yield = -0.2198 or -21.98%.

Part 2.

a. The arithmetic average of annual return on large-company stocks in nominal terms is equal to 14.5%.

b. For arithmetic average annual return in real terms, we have:

(1 + 0.145) = (1 + r)(1 + 0.044)

r = (1.145/1.044) - 1

r = 9.67%

Part 3.

a. For real return on the long-term government bonds, we would apply Fisher equation:

(1 + i) = (1 + r)(1 + h)

Where:

(1 + 0.066) = (1 + r)(1 + 0.033)

1 + r = 1.066/1.033

r = 3.195%

b. For real return on long-term corporate bonds:

(1 + 0.067) = (1 + r)(1 + 0.033)

1 + r = 1.067/1.033

r = 3.291%

Answer:

Given the information you provided, we can model cellular phone usage over time with an exponential growth model. An exponential growth model follows the equation:

`y = a * b^(x - h) + k`

where:

- `y` is the quantity you're interested in (cell phone usage),

- `a` is the initial quantity (34 million in 1995),

- `b` is the growth factor (1.22, representing 22% growth per year),

- `x` is the time (the year),

- `h` is the time at which the initial quantity `a` is given (1995), and

- `k` is the vertical shift of the graph (0 in this case, as we're assuming growth starts from the initial quantity).

So, our specific model becomes:

`y = 34 * 1.22^(x - 1995)`

To find the cellular usage in 2003, we plug 2003 in for x:

`y = 34 * 1.22^(2003 - 1995)`

Calculating this out will give us the cellular usage in 2003.

Let's calculate this:

`y = 34 * 1.22^(2003 - 1995)`

So,

`y = 34 * 1.22^8`

Calculating the above expression gives us:

`y ≈ 97.97` million.

So, the cellular phone usage in 2003, according to this model, is approximately 98 million.
