Answer:

64 poles

Step-by-step explanation:

Given the question :

Fence posts are erected 5m apart (with a post at each corner) to support fencing round a rectangular field. If the field measures 100m by 60m, how many posts are needed?

Dimension of rectangular field = 100m by 60m

Length = 100m ; breadth = 60m

Since it is erected around the corners of the field, we need to calculate the entire perimeter of the rectangular field.

Perimeter of a rectangle : 2( length + breadth)

Perimeter = 2(100 +60) = 2(160) = 320m

Since the posts are erected 5m apart, the number of post needed will be :

Perimeter / 5

= 320 / 5

= 64 poles

Answer:

3/8

Step-by-step explanation:

Consider all the possible ways to get two heads, HHT, HTH and THH. There are 2⋅2⋅2=8 possible combinations in total. Therefore, the answer is 3/8.

The correct answer is (d) in the money. The XYZ 30 put sold at 3 is in the money because the strike price is lower than the current market price of XYZ, indicating the potential for the option holder to gain if they were to exercise the option.

To determine the status of an XYZ 30 put option sold at 3 when XYZ is trading at 40, we need to understand the concepts of "at parity," "at the money," "out of the money," and "in the money" in options trading.

- At parity: An option is said to be at parity when its market price is equal to its intrinsic value. Intrinsic value refers to the amount by which an option is in the money. If an option is at parity, there is no inherent gain or loss in holding the option.

- At the money: An option is considered at the money when the strike price of the option is equal to the current market price of the underlying asset. In this case, the XYZ 30 put would be considered at the money if the XYZ stock is trading at 30, which is not the case in this scenario.

- Out of the money: An option is out of the money when the strike price is higher for a put option (or lower for a call option) than the current market price of the underlying asset. In this scenario, since the XYZ 30 put has a strike price of 30 and XYZ is trading at 40, the put option is out of the money.

- In the money: An option is in the money when the strike price is lower for a put option (or higher for a call option) than the current market price of the underlying asset. In this case, since the XYZ 30 put has a strike price of 30 and XYZ is trading at 40, the put option is in the money.

Therefore, the correct answer is (d) in the money. The XYZ 30 put sold at 3 is in the money because the strike price is lower than the current market price of XYZ, indicating the potential for the option holder to gain if they were to exercise the option.

Step-by-step explanation:

well we know that every angle in a tringle adds up to 180 degrees.

so we know that 64 + angle 1 + angle 2 = 180

180-64=116

and since they are congruent (same value as one another) you just divide 116 by 2 and boom!

A 60-minute video at 40 frames per second requires approximately 288 GB of video storage.

Total frames = frame rate \(\times\) duration

Total frames = 40 frames/second \(\times\) 60 minutes \(\times\) 60 seconds/minute

Total frames = 144,000 frames

Total storage = Total frames \(\times\) size of a single frame

Total storage = 144,000 frames \(\times\) 2MB/frame

Total storage = (144,000 frames \(\times\) 2MB/frame) / 1024 MB/GB

Total storage = 288,000 MB / 1024 MB/GB

Total storage ≈ 288 GB

Answer:

¼

Step-by-step explanation:

From the question given above, the following data were obtained:

Blue (B) seed = 3

Purple (P) seed = 1

Total (S) = 1 + 3 = 4

The probability of her choosing a purple seed can be obtained as follow:

Event of purple seed, n(P) = 1

Total, n(S) = 4

Probability of purple seed, P(P) =?

P(P) = n(P) / n(S)

P(P) = ¼

Therefore, the probability of her choosing a purple seed is ¼.

There are 10 possible outcomes in the sample space.

To determine the number of outcomes in the sample space, we need to consider the number of possible sequences of paint jars the painter can try before finally obtaining the purple color.

Since the painter does not repeat any of the jars, we can count the outcomes by considering the possible positions of the purple jar within the sequence.

In the first attempt, there are 4 different jars she can choose from.

If the purple jar is not chosen in the first attempt, there are 3 remaining jars she can choose from in the second attempt.

If the purple jar is not chosen in the second attempt, there are 2 remaining jars she can choose from in the third attempt.

If the purple jar is not chosen in the third attempt, there is only 1 remaining jar she can choose from in the fourth attempt.

Since the purple jar must be chosen at some point, it will be one of the four attempts. Therefore, the total number of outcomes in the sample space is the sum of the outcomes at each step:

4 + 3 + 2 + 1 = 10

So, there are 10 possible outcomes in the sample space.

T: P₂ → P4, is the transformation that maps a polynomial p(t) into the polynomial p(t)- t²p(t). Let’s find out the image of p(t) = 6 + t - t² and show that T is a linear transformation and find the matrix for T relative to the bases (1, t, t²) and (1, t, 12, 1³, 14).

Step by step answer:

a) The image of p(t) = 6 + t - t² is;

T(p(t)) = p(t) - t² p(t)T(p(t))

= (6 + t - t²) - t²(6 + t - t²)T(p(t))

= 6 - t + 5t² - 13t + 14T(p(t))

= 20 - t + 5t²

Therefore, the image of p(t) = 6 + t - t² is 20 - t + 5t².

b)To show T as a linear transformation, we need to prove that;

(i)T(u + v) = T(u) + T(v)

(ii)T(cu) = cT(u)

Let u(t) and v(t) be two polynomials and c be any scalar.

(i)T(u(t) + v(t))

= T(u(t)) + T(v(t))

= [u(t) + v(t)] - t²[u(t) + v(t)]

= [u(t) - t²u(t)] + [v(t) - t²v(t)]

= T(u(t)) + T(v(t))

(ii)T(cu(t)) = cT (u(t))= c[u(t) - t²u(t)] = cT(u(t))

Therefore, T is a linear transformation.

c)The standard matrix for T, [T], is determined by its action on the basis vectors;

(i)T(1) = 1 - t²(1) = 1 - t²

(ii)T(t) = t - t²t = t - t³

(iii)T(t²) = t² - t²t² = t² - t⁴

(iv)T(1) = 1 - t²(1) = 1 - t²

(v)T(14) = 14 - t²14 = 14 - 14t²

Therefore, the standard matrix for T is;\($$[T] = \begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & -1 & 1 \\ 0 & -13 & 0 \\ 0 & 0 & -14 \end{bmatrix}$$\)Hence, the solution of the given problem is as follows;(a) The image of p(t) = 6 + t - t² is 20 - t + 5t².(b) T is a linear transformation because it satisfies both the conditions of linearity.(c) The standard matrix for T relative to the bases (1, t, t²) and (1, t, 12, 1³, 14) is;\($$[T] = \begin{bmatrix} 1 & 0 & 0 \\ 0 & 1 & 0 \\ 0 & -1 & 1 \\ 0 & -13 & 0 \\ 0 & 0 & -14 \end{bmatrix}$$\)

The depth of the scientist below sea level after traveling downward for 102 seconds can be found by multiplying her speed by the time she traveled:

Distance = Speed x Time

Distance = 4.2 feet/second x 102 seconds

Distance = 428.4 feet

Since she traveled straight down, this distance is also her depth below sea level.

Next, we need to find how far she ascended. The distance she traveled upward can be found in the same way:

Distance = Speed x Time

Distance = 1.9 feet/second x 112 seconds

Distance = 212.8 feet

However, since she traveled upward, this distance is subtracted from her previous depth:

Final depth below sea level = Initial depth below sea level - Distance traveled upward

Final depth below sea level = 428.4 feet - 212.8 feet

Final depth below sea level = 215.6 feet

Therefore, the scientist is 215.6 feet below sea level at this point.

The value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1 ​.

According to the question,

We have the following equation:

f-2g+3=2f-39+2=1 ​

Now, we will equate both these equations to 1:

f-2g+3 = 1

Subtracting 3 from both sides:

f-2g = 1-3

f-2g = -2 ..(1)

2f-39+2 = 1

2f -37 = 1

Adding 37 to both sides:

2f = 1+37

2f = 38

Dividing by 2 on both sides:

f = 38/2

f = 19

Putting this value of f in equation 1:

f-2g = -2

19-2g = -2

-2g = -2-19

-2g = -21

g = 21/2

g = 10.5

Hence, the value of f is 19 and the value of g is 10.5 after solving the simultaneous equation, f-2g+3=2f-39+2=1​.

The rate of increase in the radius is larger because, as the radius increases, the rate of change in the volume increases as well.

(a) The rate at which the volume of the balloon is increasing can be found by using the formula for the volume of a sphere: V = (4/3)πr3. Differentiating this with respect to time gives the rate at which the volume is increasing: dV/dt = 4πr2(dr/dt). When r = 5.20 cm and dr/dt = 0.840 cm/s, the rate at which the volume is increasing is 4π(5.20 cm)2(0.840 cm/s) = 4.15 cm3/s.

(b) When the radius is 13.90 cm, the rate at which the volume is increasing is 4π(13.90 cm)2(dr/dt). For this rate to remain constant, dr/dt must increase. Thus, the rate at which the radius is increasing must be larger than 0.840 cm/s.

(c) Physically, this is because the rate of change in the volume of the balloon increases as the radius increases. As the radius increases, the surface area of the balloon increases, allowing more air to enter the balloon. Thus, in order to maintain a constant volume rate, the rate of increase in the radius must also increase.
