Answer:

Find roots of x4−81=0 by solving for x. x=3,−3

Step-by-step explanation:

The given equation \(x^4\) - 81 = 0 has a total of two real roots x = 3 and

x = -3.

We have,

The given equation \(x^4\) - 81 = 0 can be factored as a difference of squares:

\((x^2)^2 - 9^2 = 0\\(x^2 - 9)(x^2 + 9) = 0\)

Further simplifying:

(x - 3)(x + 3)(x² + 9) = 0

From this factorization, the equation has two linear factors (x - 3) and

(x + 3) and one quadratic factor (x² + 9).

The linear factors, (x - 3) and (x + 3), will each provide one real root since they are linear equations.

x = 3 and x = -3.

The quadratic factor (x² + 9) has no real roots.

This is because the discriminant (b² - 4ac) of the quadratic equation is negative (a = 1, b = 0, c = 9), indicating that there are no real solutions.

Therefore,

The given equation \(x^4\) - 81 = 0 has a total of two real roots,

x = 3 and x = -3.

Answer: The measure of Angle A is 46 degrees.

Step-by-step explanation:

Complementary angles are angles that when both added together are equal to 90 degrees. So the measure of angle A plus the measure of angle B is equal to 90 or 3x - 2 + 2x + 12 = 90. Add like terms so you get 5x + 10 = 90. Subtract 10 on both sides you get 5x = 80. Divide by 5 on both sides and you get x = 16. To find the measure of angle A, plug in your x value. So M<A = 3(16) - 2. Ange A is equal to 46. I double checked my answer too and plugged my x value into M<B and got 44. So indeed 44 + 46 = 90.

t = 3 s and t = 4 s

Step-by-step explanation:

Given that,

A projectile is fired straight up from ground level with an initial velocity of 112ft/s. Its height as a function of time t is given by :

\(h=-16t^2+112t\)

We need to find the interval of time during which the projectile’s height exceeds 192 feet. It means put h = 192 feet

So,

\(-16t^2+112t=192\\\\-16t^2+112t-192=0\)

The above is a quadratic equation, it can be solved using middle term splitting as follow :

\(16 (t^2 - 7t + 12) = 0\\\\16 (t - 4)(t - 3) = 0\\\\t=4\ s\ \text{and}\ t=3\ s\)

Hence, at t = 3 s and t = 4 s, the projectile’s height exceeds 192 feet above the ground.

The odds of the soccer player scoring a goal is 4. The correct option is (b).

The odds of an event happening can be calculated by dividing the number of successful outcomes by the number of unsuccessful outcomes.

In this case, the soccer player scored a goal 3 times out of 15 attempts.

The number of successful outcomes is 3 (goals scored), and the number of unsuccessful outcomes is 15 - 3 = 12 (failed attempts).

Therefore, the odds of the soccer player scoring a goal can be expressed as 3:12, which can be simplified to 1:4.

To match the given answer choices, we can rewrite the odds as a fraction by dividing both sides by the number of successful outcomes:

Odds = Successful outcomes : Unsuccessful outcomes

Odds = 3 : 12

Odds = 3/3 : 12/3

Odds = 1 : 4

It will take approximately 12.15 years for the investment to reach $5000.

Compound interest is an interest calculated on the principal amount as well as on the previously earned interest. The formula for compound interest is:

P = A (1 + r / n) ^ (n * t),

where, P is the principal amount, A is the amount, r is the rate of interest, n is the number of times interest is compounded per year, and t is the time for which the investment is made.

Jose invests $2000 at an annual compound interest of 8%.

Let's assume that it takes t years to reach $5000.

We know that the initial investment is $2000.

Therefore, we can use the formula of compound interest to calculate the amount after t years:

$5000 = $2000 (1 + 0.08 / 1) ^ (1 * t)

Simplifying the above equation,

we get:$(1.08) ^ t = 5 / 2

Taking the natural logarithm of both sides, we get:

t ln (1.08)

= ln (5 / 2)t

= ln (5 / 2) / ln (1.08)t

Answer:

Rs. 300

Step-by-step explanation:

The bicycle marked price = Rs. 2000

The amount the customer bought the bike given that there was some discount allowed by the shopkeeper including VAT = Rs. 1921

The VAT applied = 13%

The amount given as the discount = Required

The VAT is applied to the selling price

Let d represent the discount amount, we have;

The selling price = 2000 - d

The amount paid as VAT = (2,000 - d) × 13% = (2,000 - d) × 0.13

The amount the customer bought it including VAT = The selling price + The amount paid as VAT

The amount the customer bought it including VAT = Rs. 1921

∴ 1921 = 2000 - d + (2,000 - d) × 0.13 = 2,260 - 1.13·d

1.13·d = 2,260 - 1,921 = 339

d = 339/1.13 = 300

The amount given as discount, d = Rs. 300

the likelihood that the sample proportion of family units investing more than $125 a week is between 0.24 and 0.41 is 0.841 or generally 84.1% 

From the given data, the sample size given in the problem is  149. 

and the population extent of families investing more than $125 a week on foodstuffs is 0.36.

Now, we have to find the likelihood that the sample proportion of families investing more than $125 a week on basic supplies is between 0.24 and 0.41.

The standard blunder(error) of the sample extent (proportion) can be calculated utilizing the taking after equation:

SE (sample extent) = √[(p*(1-p))/n].

Where,

p is the population proportion

n is the sample estimate.

SE = √[(0.36*(1-0.36))/149]

SE = 0.049.

Able to utilize the standard typical distribution to discover the likelihood. We have to standardize the test extent utilizing the taking after equation:

z = (p - P) / SE

Where P is the population extent,

p is the sample extent (proportion)

and SE is the standard error.

For p = 0.24, z = (0.24 - 0.36) / 0.049 = -2.45

For p = 0.41, z = (0.41 - 0.36) / 0.049 = 1.02

with the help of a standard ordinary table or a calculator, be ready to discover the probabilities related to these z-scores:

P(z < -2.45) = 0.007

P(z < 1.02) = 0.848

Hence, the likelihood that the sample extent (proportion)  of family units investing more than $125 a week is between 0.24 and 0.41 is:

P(-2.45 < z < 1.02)

= P(z < 1.02) - P(z < -2.45)

= 0.848 - 0.007

= 0.841

Therefore P(-2.45 < z < 1.02) = 0.841 or roughly 84.1%

In order to calculate the time it will take for Andrew to settle the loan, we can use the formula for compound interest. So, it will take Andrew approximately 5.22 years to settle the loan.

The formula is given as A = P(1 + r/n)^(nt), Where: A = the final amount, P = the principal (initial amount borrowed), R = the annual interest rate, N = the number of times the interest is compounded in a year, T = the time in years.

We know that Andrew borrowed R200 000 from a bank at an annual interest rate of 5.25% compounded quarterly and that he will make repayments of R6 000 at the end of every 3 months.

Since the first repayment will be made 3 months from now, we can consider that the initial loan repayment is made at time t = 0. This means that we need to calculate the value of t when the total amount repaid is equal to the initial amount borrowed.

Using the formula for compound interest: A = P(1 + r/n)^(nt), We can calculate the quarterly interest rate:r = (5.25/100)/4 = 0.013125We also know that the quarterly repayment amount is R6 000, so the amount borrowed minus the first repayment is the present value of the loan: P = R200 000 - R6 000 = R194 000

We can now substitute these values into the formula and solve for t: R194 000(1 + 0.013125/4)^(4t) = R200 000(1 + 0.013125/4)^(4t-1) + R6 000(1 + 0.013125/4)^(4t-2) + R6 000(1 + 0.013125/4)^(4t-3) + R6 000(1 + 0.013125/4)^(4t)

Rearranging the terms gives us: R194 000(1 + 0.013125/4)^(4t) - R6 000(1 + 0.013125/4)^(4t-1) - R6 000(1 + 0.013125/4)^(4t-2) - R6 000(1 + 0.013125/4)^(4t-3) - R200 000(1 + 0.013125/4)^(4t) = 0

Using trial and error, we can solve this equation to find that t = 5.22 years (rounded to 2 decimal places). Therefore, it will take Andrew approximately 5.22 years to settle the loan.

To have $3,793,695.00 in his retirement account when he retires, Derek would need the rate on the account to be approximately 5.89%.

To calculate the required rate on Derek's retirement account, we can use the formula for the future value (FV) of an annuity:

\(FV = P * [(1 + r)^n - 1] / r\)

Where:

FV is the desired future value

P is the amount deposited on each birthday

r is the interest rate per period

n is the total number of periods (number of birthdays)

In this case, the desired future value (FV) is $3,793,695.00, the amount deposited on each birthday (P) is $14,455.00, and the total number of periods (n) is the difference between Derek's final and initial birthday, which is 68 - 27 = 41.

We need to solve for the interest rate (r). Rearranging the formula:

\(r = [(FV / P) / [(1 + r)^n - 1]]\)

Substituting the given values, we have:

\(r = [(3,793,695.00 / 14,455.00) / [(1 + r)^{41} - 1]]\)

We can use numerical methods or trial and error to find the value of r that satisfies the equation. By using these methods, the approximate value of r is found to be 0.0589 or 5.89%.

Therefore, Derek would need the rate on his retirement account to be approximately 5.89% for him to have $3,793,695.00 in it when he retires.

Let \($S$\) be the subset of \($\mathbb{R}^3$\) consisting of all vectors such that \(x_1 + x_2 + x_3 = 0$.\) To determine if $S$ is a subspace of \($\mathbb{R}^3$\), we need to check the following three conditions:

\($S$\) contains the zero vector\(: $(0,0,0) \in S$ since $0+0+0=0$.\)

$S$ is closed under addition: if\($\mathbf{u}, \mathbf{v} \in S$,\)then \($(u_1+v_1)+(u_2+v_2)+(u_3+v_3) = (u_1+u_2+u_3) + (v_1+v_2+v_3) = 0+0 = 0$, so $\mathbf{u}+\mathbf{v} \in S$.\)

$S$ is closed under scalar multiplication: if\($\mathbf{u} \in S$ and $c$ is\) a scalar, then \(c\mathbf{u} = c(u_1,u_2,u_3) = (cu_1,cu_2,cu_3)$ and $(cu_1+cu_2+cu_3) = c(u_1+u_2+u_3) = c\cdot0 = 0$, so $c\mathbf{u} \in S$.\)

Since all three conditions are satisfied, we conclude that \($S$\) is a subspace of\($\mathbb{R}^3$.\)Therefore, the correct answer is (a) is a subspace because it has a zero element.
