Answer:

The graph will be translated down 2 units.

The new horizontal asymptote is y=2 because the graph now crosses over the y axis at 2. This is at the point (0,2).

Step-by-step explanation:

Q1. By linear pair, I know that 72* + unknown angle = 180*

therefore unknown angle = 180-72 = 108*

Now because this is a pentagon, the total of all interior angles of a polygon equals 540*

so 108* + 100* + 110* + 45* (Half of 90 , written as a semi-square) + Y* = 540

Y* = 540 - 363 = 177*

Q2. 360 - (80+70+110) = q

q = 360 - 220 =  140*


Q3. 160+160+ S* = 360*

360* - 320* = S*

S* = 40*

Hope it helps

Answer: All of the slopes are the same.

A fair die is rolled twice, then the probability that the sum is greater than 10 is 1/12.

Finding the total number of possible outcomes when the dice is rolled twice:

A total of 6*6 = 36 outcomes are possible as there are 6 outcomes for the first roll and 6 outcomes for the second.

Making a list of all results that add up to greater than 10:

5 + 6 = 11

6 + 5 = 11

6 + 6 = 12

There are only three favorable outcomes.

So, the probability of getting a number greater than 10 =

[tex]\frac{no\ of\ favorable\ outcomes}{total\ number\ of\ possible\ outcomes}[/tex]

P(sum > 10) = 3/36 = 1/12

Therefore, there is a 1/12 probability that the sum of the two dice is greater than 10.

It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.

The formula for finding the MOE:

MOE =Z_{score} * s/√n

Where  Z_{score} is the z score at the confidence interval

            s is the standard deviation

            n is the number of samples.

We have:

MOE = 2% = 0.02 and

α = 1-0.95 = 0.05

Let's assume the value of p = 0.5, and q = 0.5

From the table:

Z_(0.05/2)

= Z_(0.025)

= 1.96

n = 2401

For part (b):

p = 18% = 0.18, and q = 0.82

so, we get,

n = 1417.5 = 1417

Thus, the sample size for part (a) is 2401, and the sample size for part (b) is 1417 if the margin of error is no more than two percentage points and use a confidence level of 95%

The expected value for the game is 2/3.

The average value we would anticipate to find if we repeated an experiment several times is the anticipated value of a random variable. It is calculated by averaging the outcomes of multiplying each potential result of the random variable by the associated probability. In other words, it's the weighted average of all potential possibilities, with the weights being the likelihoods that each outcome would actually happen. In several disciplines, including finance, economics, and engineering, predictions and judgements are made using the expected value, a fundamental idea in probability theory.

Let us suppose the profit = X.

Thus,

Probability of winning twice our wager = 1/6 thus, the expected value is:

(2)(1/6) = 1/3

No, for profit equal to wager we have:

(1)(1/3) = 1/3

The total expected value is:

E(X) = (1/3) + (1/3) + 0 = 2/3

Hence, the expected value for the game is 2/3.

Using division operation, the number of cans collected by each of the 18 students is 17.

Division operation is one of the four basic mathematical operations, including addition, subtraction, and multiplication.

Division operation involves the dividend (the number being divided), the divisor (the number dividing the dividend), and the product called the quotient.

The total number of students engaged in the can collection project = 18

The total number of cans collected = 306

The number of cans collected by each, if each collected the same quantity = 17 (306 ÷ 18)

Thus, based on a division operation, the number of cans each student collected is 17.

Step-by-step explanation:

The mean absolute deviation (MAD) of the data set include the following: A. 11.

In Mathematics, MAD is an abbreviation for mean absolute deviation and the mean absolute deviation (MAD) of a data set can be calculated by using this formula;

MAD = 1/n ∑|x - μ|

Where:

By substituting the given parameters into the MAD formula, we have the following;

MAD = 1/10 [(325 - 290) +  (310 -290) +(289-290)+(288-290)+(285-290)+(285-290)+(285-290) + (280-290) + (280-290) + (273-290)]

MAD = 1/10(35 + 20+1+2+5+5 +5 + 10 + 10 + 17).

MAD = 1/10(110)

MAD = 11

The temperature is rising at a rate of 7.5 degrees Celsius per second along the bug's path after 2 seconds.

A derivative of a function with regard to an independent variable is defined as differentiation. In calculus, differentiation can be used to calculate the function per unit change in the independent variable.

We can use the chain rule of differentiation to find how fast the temperature is changing on the bug's path. Let T denote the temperature function, and let x and y be functions of time t given by x = sqrt(2) + t and y = 1 + t/2. Then the temperature function on the bug's path is given by T(x(t), y(t)), and we want to find dT/dt at t = 2.

Using the chain rule, we have:

dT/dt = dT/dx * dx/dt + dT/dy * dy/dt

We are given Tx(2, 9) = 7 and Ty(2, 9) = 1, so we can evaluate the partial derivatives at (x, y) = (2, 9):

dT/dx(2, 9) = 7

dT/dy(2, 9) = 1

To find dx/dt and dy/dt, we can take the derivatives of x and y with respect to t:

dx/dt = 1

dy/dt = 1/2

Now we can plug in the values:

dT/dt = 7 * 1 + 1 * 1/2

dT/dt = 7.5

Therefore, the temperature is rising at a rate of 7.5 degrees Celsius per second along the bug's path after 2 seconds.

Step-by-step explanation:

To determine if this is a good investment, we can use present value calculations to see what the $3,000 payment in 4 years is worth today:

Present value of $3,000 in 4 years at 10% interest rate = $3,000 / (1 + 0.10)^4 = $2,102.50.

If we invest $2,000 today and get a payment of $2,102.50 in 4 years, our net gain would be:

Net gain = $2,102.50 - $2,000 = $102.50

Therefore, investing $2,000 today with an interest rate of 10% and receiving $3,000 in 4 years would yield a net gain of $102.50.

While any gain is better than no gain, a return of $102.50 on an investment of $2,000 over a period of 4 years may not be considered a great investment. It's up to the individual to decide whether they feel that the potential gain is worth the initial investment and risk involved.

Using the fundamental identities, the equivalent expressions are hereby matched as follows:

a. 2 csc (θ) cot (θ) = 2 sin²(θ) / (sin(θ) + cos(θ))

b. 2 sec (θ) tan (θ) = (2 sec²(θ)) - 2 sec(θ)

c. 2 cot (θ) = 2 / sin(θ) - csc(θ)

d. 2 csc² (θ) = 2 / (csc(θ) - 1)(csc(θ) + 1)

Using the fundamental identities, rewrite each expression as follows:

a. 2 csc (θ) cot (θ) = 2 / sin(θ) * cos(θ) = 2 cos(θ) / sin(θ) = 2 / sin(θ) - 2 / sin(θ) + 2 cos(θ) / sin(θ) = 2 / sin(θ) - 2 / (1 + cot(θ)) = (2 - 2 sin(θ)) / (sin(θ) + cos(θ)) = (2 sin²(θ)) / (sin(θ) + cos(θ))

b. 2 sec (θ) tan (θ) = 2 / cos(θ) * sin(θ) / cos(θ) = 2 sin(θ) / cos²(θ) = 2 / cos²(θ) - 2 / cos(θ) = (2 sec²(θ)) - 2 sec(θ)

c. 2 cot (θ) = 2 cos(θ) / sin(θ) = 2 / sin(θ) - 2 / sin²(θ) = 2 / sin(θ) - csc(θ)

d. 2 csc² (θ) = 2 / sin²(θ) = 2 / (1 - cos²(θ)) = 2 / (1 - cos(θ))(1 + cos(θ)) = 2 / (csc(θ) - cot(θ))(csc(θ) + cot(θ)) = 2 / (csc(θ) - 1)(csc(θ) + 1)

Therefore, the matches are:

a. 2 csc (θ) cot (θ) = 2 sin²(θ) / (sin(θ) + cos(θ))

b. 2 sec (θ) tan (θ) = (2 sec²(θ)) - 2 sec(θ)

The balance on the account of the Telkom account holder, every month was :

We know that May was one and half times June :

M = 1. 5 x J

July was R 50 more than June :

L = J + 50

Total spent was R 575 :

M + J + L = R 575

Then we can solve by substitution:
( 1. 5 J ) + J + ( J + 50 ) = 575

3. 5 J + 50 = 575

3. 5 J = 525

J = 525 / 3. 5 = R 150

L would be:

Okay, to find the maximum number of shovels that can be produced with $10,000, we need to do the following:

1) Set the cost function C(N(h)) = 10,000. So: 990h + 430 = 10,000

2) Subtract 430 from both sides: 990h = 9,570

3) Divide both sides by 990: h = 9.75 (round to 10 hours)

4) Substitute 10 hours into the function for number of shovels:

N(10) = 30(10) = 300 shovels

Therefore, the maximum number of shovels that can be produced with $10,000 is 300 shovels.
