The price of 3 chairs and 4 tables is Rs 7540.What is the price of 1 table if the price of a chair is Rs 220.
Given parameters:
Number of chairs = 3
Number of tables = 4
Cost of 3 chairs and 4 tables = Rs 7540
Price of 1 table = Rs220
Unknown:
Price of 1 table = ?
Solution:
Let the cost of 1 table = t
So,
3(220) + 4(t) = 7540
660 + 4t = 7540
4t = 7540 - 660
4t = 6880
t = Rs. 1720
The cost of 1 table is Rs. 1720

if \(v=v_{1} +v_{2}\), where \(v_{1}\) and \(v_{2}\) are not both 0 and \(u=-3v\), find the measure of the angle between \(u\) and \(v\).
Given:
\(\frac{u*v}{||u|| ||v||}\)
If θ is the angle between u and v, then
u • v = ||u|| ||v|| cos(θ)
Since u = -3v, we have
u • v = (-3v) • v = -3 ||v||²
and
||u|| = ||-3v|| = 3 ||v||
If v₁ and v₂ are both not zero, then ||v| ≠ 0.
Then
cos(θ) = (-3 ||v||²) / (3 ||v|| ||v||) = 1
which means θ = π rad = 180°.

Answer:
11 meters.
Step-by-step explanation:
The important thing to note here is that the backyard is a square. Since it's a square, all of its sides all equivalent in length. Thus, let's find the length of the sides. To do this, we use the area formula.
The formula for the area of a square is:
\(A=n^2\)
Where n is a side. Since we know the area already, we can find n. Find n:
\(121=n^2\\n=11\)
Since every side in a square are equivalent, all sides are 11 meters in length.
Therefore, each section of the fence should be 11 meters long.

(a) An angle measures 28°. What is the measure of its complement?
(b) An angle measures 132°. What is the measure of its supplement?
Complementary angles has sum of \(90^{o}\) and supplementary angles have sum of \(180^{o}\) , The answer is \(62^{o}\) and \(48^{o}\) .
What do you mean by angle?When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together.
What is complementary and supplementary angle?When two angles' measurements add up to 90 degrees, they are said to be complementary. When two angles' measures sum up to 180 degrees, they are said to be supplementary. Keeping in mind that the letter s follows the letter c in the alphabet and that 180 is greater than 90 can help you avoid conflating these definitions.
\(28^{o}\)
complement = \(90^{o}-28^{o}\) = \(62^{o}\)
\(132^{o}\)
supplement= \(180^{o}-132^{o}\) = \(48^{o}\)

The sum of two numbers is 17 and their dofference is 7. What are the two numbers?
Answer:
The two number are 15 and 5
Step-by-step explanation:
Let both numbers be first and second.
According to the problem statement:
first + second = 20 (Consider this as 1st equation)
first – second = 10 (Consider this as 2nd equation)
Add both equations:
first + second + first – second = 20 + 10
2 * first = 30
first = 30 / 2
first = 15
So from this we get first = 15, put this value in any equation i.e.
first + second = 20 (Put the value of first in this equation)
15 + second = 20
second = 20 – 15
second = 5
So, the numbers are 15 and 5.
12 and 5 the two numbers

Write an equation for a polynomial function whose graph intercepts the
horizontal axis at -7, 8, and 15.
Answer:
y=(x+7)(x-8)(x-15)
Step-by-step explanation:
yw
An equation for a polynomial function with given intercepts is
\(P(x)=x^3-16x^2-41x+840\)
Given :
The intercepts at the horizontal axis at -7, 8, and 15.
so, the x intercepts are -7, 8, and 15.
Lets write the x intercepts in factor form
if 'a' is x intercept then (x-a) is a factor
x intercepts are -7, 8, and 15.
the factors are
\((x-(-7)) (x-8)(x-15)\\(x+7)(x-8)(x-15)\)
Now to write the polynomial we multiply all the factors
\(P(x)=(x+7)(x-8)(x-15)\\P(x)=\left(x^2-x-56\right)\left(x-15\right)\\P(x)=x^3-16x^2-41x+840\)

a man has been driving a second hand car for the past four years. over these four years he managed to save 16% as a deposit of the price of the brand new car he wants to buy. the price of the new car is 750 000... calculate the amount he saved for the deposit
Answer:
$120,000
Step-by-step explanation:
Provided that
The price of the new car is $750,000
And, the saving percent is 16%
We need to calculate out the saving amount for the deposit
Therefore, the saving amount is
= $750,000 × 16%
= $120,000
Basically we multiply these two things to each other in order to get the saving amount
Determine an interval that a root of
f(x)=5cosx)−√x^2 +1+2^x−1
lies on
The root of the function \(\(f(x) = 5\cos(x) - \sqrt{x^2 + 1} + 2^{x-1}\)\) lies within the interval \(\([-1, 0]\)\).
To find the interval where the root of the given function lies, we need to analyze the behavior of the function within certain intervals. Let's consider the interval \(\([-1, 0]\)\).. For \(\(x = -1\)\), we have \(\(f(-1) = 5\cos(-1) - \sqrt{(-1)^2 + 1} + 2^{-2}\)\). Since \(\(\cos(-1)\)\) is positive and the other terms are also positive, the value of \(\(f(-1)\)\) is positive.
Now, for \(\(x = 0\)\), we have \(\(f(0) = 5\cos(0) - \sqrt{0^2 + 1} + 2^{-1}\)\). Since \(\(\cos(0)\)\) is positive and the other terms are positive, the value of \(\(f(0)\)\) is positive.
As the function is continuous, and it changes sign from positive to negative within the interval \(\([-1, 0]\)\) (as \(\(f(-1)\)\) and \(\(f(0)\)\) have different signs), by the Intermediate Value Theorem, there exists at least one root of the function within this interval. Therefore, we can conclude that the root of \(\(f(x)\)\) lies within the interval \(\([-1, 0]\)\).

Plot the point whose cylindrical coordinates are given. Thenfind the rectangular coordinates of this point.
1. a] (2, π/4, 1)
b] (4, -π/3, 5)
The rectangular coordinates of the point are approximately (1.414, 1.414, 1).
The rectangular coordinates of the point are approximately (-2, -3.464, 5).
The point with cylindrical coordinates (2, π/4, 1) corresponds to the cylindrical radius of 2, angle of π/4 (45 degrees), and height of 1. To find the rectangular coordinates, we can use the following formulas:
x = r * cos(θ)
y = r * sin(θ)
z = h
Plugging in the values, we get:
x = 2 * cos(π/4) ≈ 1.414
y = 2 * sin(π/4) ≈ 1.414
z = 1
b] The point with cylindrical coordinates (4, -π/3, 5) corresponds to the cylindrical radius of 4, angle of -π/3 (-60 degrees), and height of 5. Using the same formulas as above, we can calculate the rectangular coordinates:
x = 4 * cos(-π/3) ≈ -2
y = 4 * sin(-π/3) ≈ -3.464

Peter would like to invest in the U.S share market. Consider the following table, which gives a security analyst’s expected return on two stocks in two particular scenarios for the rate of return on the market:
Market Return
Aggressive Stock
Defensive Stock
6%
-3%
8%
22%
40%
11%
The probability of the pessimistic (optimistic) scenario is 90% (10%) and the risk-free rate is 3%. What is the equation of SML and the alphas for the aggressive and defensive stock? Please keep 2 decimals in your answer.
The Security Market Line (SML) is a graphical representation of the Capital Asset Pricing Model (CAPM). It depicts the return that an investor should expect to earn by holding an efficient portfolio of risky assets as a function of systematic risk, beta.
The CAPM equation defines the relationship between expected return and beta, which is reflected in the slope of the SML. The equation for the SML is:E(Ri) = Rf + βi(E(RM) - Rf)whereE(Ri) = the expected return on asset iRf = the risk-free rateβi = the asset’s systematic risk (beta)E(RM) = the expected return on the market portfolioWhen using the CAPM to price securities, the relevant measure of risk is not the total risk (variance), but rather the systematic risk (beta), which is covariance with the market portfolio divided by the variance of the market portfolio.
Below is the computation of the SML and the alpha for the Aggressive and Defensive Stock:SML = 3% + [0.6(6% - 3%)] = 4.8%Alpha of Aggressive Stock = -3% - 4.8% = -7.8%Alpha of Defensive Stock = 11% - 4.8% = 6.2%

What is inequality?Inequalities specify the relationship between two values that are not equal. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal
Given:
550 + 8b < 925
Solve the inequality by subtracting 550 on both sides,
