Using a multiplier, find 85% of £30
Answers
Answer:

Step-by-step explanation:
I don't know what you mean by multiplier but to find 85% of £30 you do:
10% of 30 which is 3
80% is 24
5% is 1.5 (to find 5% you find 10% then divide by 2)
Now add 24 and 1.5. Do not add the 10% becuase we used it to help the 80%.

Answers
(a)i. Evaluating the constant:
\($$\int_{-1}^{1} c(1+x)(1-2x) dx = 1$$$$\implies c = \frac{3}{4}$$\)
Therefore, the probability density function is:
\($$f(x) = \frac{3}{4} (1+x)(1-2x), -1< x < 1$$\) ii. Plotting the probability density function:
From the graph, it is observed that the density function is skewed to the left.
(b)i. The mean:
\($$E(X) = \int_{-1}^{1} x f(x) dx$$$$E(X) = \int_{-1}^{1} x \frac{3}{4} (1+x)(1-2x) dx$$$$E(X) = 0$$\)
ii. The second moment about the origin:

Therefore, the variance is:
\($$\sigma^2 = E(X^2) - E(X)^2$$$$\implies \sigma^2 = \frac{1}{5}$$\)

Answers
The total interest consumer pay on the credit card which has a daily interest rate of 0.042% is $32.08.
What is compound interest?Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.
The formula for the final amount with the compound interest formula can be given as,
\(A=P\times\left(1+\dfrac{r}{100}\right)^{t}\\\)
Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.
In the given problem,
A consumer charges a P, $2,530.16 purchase on a credit card. The card has a daily interest rate r of 0.042%. The balance is paid off at the end of 30 days. Thus the time t is 30.Put these values in the above formula as,
\(A=2530.16\times\left(1+\dfrac{0.042}{100}\right)^{30}\\\\A=2562.24\)
The interest amount paid is,
\(I=A-P\\I=2562.24-2530.16\\I=32.08\)
Thus, the total interest consumer pay on the credit card which has a daily interest rate of 0.042% is $32.08.

John is saving to buy a new car that will cost him $24,000. John started his savings at the beginning of the school year and has been able to accumulate $1000 after the first month. John plans to continue his savings at a rate proportional to the amount he still needs to save. Determine John's savings amount as function of time Hint: A variable y is said to be proportional to a variable x if y=cx for some constant c.
Answers
John's savings amount as a function of time is S(t) = $24,000 / 25. Initially, he needs to save $24,000 for a new car. After the first month, he has saved $1,000. The savings amount is directly proportional to the time elapsed. The constant of proportionality is 1/24. Thus, John's savings amount can be determined based on the remaining amount he needs to save.
John's savings amount can be represented as a function of time and is proportional to the amount he still needs to save. Let's denote the amount John needs to save as N(t) at time t, and his savings amount as S(t) at time t. Initially, John needs to save $24,000, so we have N(0) = $24,000.
We know that John has saved $1,000 after the first month, which means S(1) = $1,000. Since his savings amount is proportional to the amount he still needs to save, we can write the proportionality as:
S(t) = k * N(t)
where k is a constant of proportionality.
We need to find the value of k to determine John's savings amount at any given time.
Using the initial values, we can substitute t = 0 and t = 1 into the equation above:
S(0) = k * N(0) => $1,000 = k * $24,000 => k = 1/24
Now we have the value of k, and we can write John's savings amount as a function of time:
S(t) = (1/24) * N(t)
Since John's savings amount is proportional to the amount he still needs to save, we can express the amount he still needs to save at time t as:
N(t) = $24,000 - S(t)
Substituting the expression for N(t) into the equation for S(t), we get:
S(t) = (1/24) * ($24,000 - S(t))
Simplifying the equation, we have:
24S(t) = $24,000 - S(t)
25S(t) = $24,000
S(t) = $24,000 / 25
Therefore, John's savings amount at any given time t is S(t) = $24,000 / 25.

the linear density of a rod of length 1 m is given by (x) = 7/sqrt(x) , in grams per centimeter, where x is measured in centimeters from one end of the rod. find the mass (in g) of the rod.Multiple choice:If lim f(x) = lim g(x) = , then lim[f(x)– g(x)] i. equal 0ii. does not exist iii. depends on f and g
Answers
The mass of the rod is 140 grams. If lim f(x) = lim g(x) = L, then lim [f(x) - g(x)] = lim f(x) - lim g(x) = L - L = 0. The correct option is (i) equal 0.
To find the mass of the rod, we can integrate the linear density function over the length of the rod:
m = ∫0^100 (7/√x) dx
Using the power rule of integration, we can simplify this expression:
m = 14[√x]0^100
m = 14(10 - 0)
m = 140 grams
Therefore, the mass of the rod is 140 grams.
As for the multiple-choice question, if lim f(x) = lim g(x) = L, then we can use the limit laws to evaluate the limit of their difference:
lim [f(x) - g(x)] = lim f(x) - lim g(x) = L - L = 0
So the answer is (i) equal 0.
This result holds true for any two functions with the same limit as x approaches a particular value or infinity. The limit of their difference will always be equal to the difference of their limits, which is zero in this case. Therefore, the answer is not dependent on the specific functions f and g.

Two angles of a triangle are in the ratio of 2:3 if the third angle is 50 degree find the other two angles
the sum of the interior angles in a triangle is 180°
so
180 - 50 = 130°
130 : 5 = 26° (unit)
26 * 2 = 52°
26 * 3 = 78°
