Raj profited Rs 30,750 from lending and borrowing money.

Raj gained from lending out Rs 65,000 for 3 years at 25% per annum and lost from borrowing Rs 60,000 for 2 years at 15% per annum.

To find out how much he gained or lost, we need to calculate the interest earned from lending and the interest paid from borrowing and then find the difference between them.

Interest earned from lending = Principal x Rate x Time
= Rs 65,000 x 25% x 3
= Rs 48,750

Interest paid from borrowing = Principal x Rate x Time
= Rs 60,000 x 15% x 2
= Rs 18,000

Difference between interest earned and interest paid = Rs 48,750 - Rs 18,000
= Rs 30,750

Therefore, answer is +Rs. 30,750.

f (x) = -3x4 + 6x3 + 33x2 - 18x - 108.

The correct answer is a. f (x) = -3x4 + 6x3 + 33x2 - 18x - 108, since this is a polynomial of the lowest degree (4) that has zeros of -2 (multiplicity 2) and 3 (multiplicity 2), as well as f(0)=-108. To solve this problem, use the Factor Theorem to determine the factors of the polynomial. Since the zeros are -2 and 3, the polynomial must factor into (x+2)2 and (x-3)2. This gives us the polynomial: f (x) = -3(x+2)2(x-3)2 - 108. Finally, expand the polynomial to get the answer: f (x) = -3x4 + 6x3 + 33x2 - 18x - 108.

The amount of centiliters in a picoliter is A = 1 x 10⁻¹⁰ cL

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the first unit of measurement be represented as A

where A = centiliters

Now , the amount of Liters in a centiliter is

From the unit conversion ,

1 L = 100 cL

And , 1 cL = 10⁻² L

Now , the amount of Liters in a picoliter is

1 L = 10¹² picoliters

And , amount of centiliters in a picoliter is A

where A = 10⁻¹⁰ cL

Answer:

Let's first convert the time taken to cover the distance at 45 km/h into minutes:

3 hours and 20 minutes = 3 x 60 + 20 = 200 minutes

The distance covered by the bus at 45 km/h is:

distance = speed x time

distance = 45 km/h x 200 minutes

distance = 9000/60 km

distance = 150 km

Now, let's use the distance and the new speed of 36 km/h to calculate the time it would take to cover the same distance:

distance = speed x time

150 km = 36 km/h x time

time = distance / speed

time = 150 km / 36 km/h

time = 4.1667 hours or 4 hours and 10 minutes (rounded to the nearest minute)

Therefore, it would take approximately 4 hours and 10 minutes to cover the same distance at a speed of 36 km/h.

The area of the middle rectangle is 720 square units.

Let's label the areas of the left and right rectangles as A and C, respectively. Let's also label the area of the middle rectangle as B. We know the distance between the first and second rectangles is 18, and the distance between the second and third rectangles is 14.

Using the formula for the area of a rectangle, we can write:

90 = lw

60 = sw

where l and w are the length and width of the left rectangle, and s and w are the length and width of the right rectangle. We want to find the width of the middle rectangle, so we can label it as x:

B = lx

We know the length of the middle rectangle is 32, so we can write:

B = 32x

Now we have three equations and three unknowns. We can use the distances between the rectangles to set up two more equations:

l + s = 18

s + 32 = 14

Simplifying, we get:

l + s = 18

s = -18 + 32 = 14

We can now solve for l and s in terms of x:

l = 18 - s = 18 - 14 = 4

s = 14

Substituting these values into the equations for the areas of the left and right rectangles, we get:

90 = 4w

60 = 14w

Solving for w in each equation, we get:

w = 22.5

Now that we have found the width of the middle rectangle, which is x = 22.5, we can use the formula for the area of a rectangle to find its area:

B = lx = 32(22.5) = 720

Leon will receive ECS250.00 dollars if he exchanges US$100.00 at this bank.

If ECS2.60 is equivalent to US$1.00, then the exchange rate from US dollars to EC dollars is 1:2.60.

To find out how much ECS dollars Leon will receive for US$100.00, we first need to convert US$100.00 to EC dollars using the exchange rate:

US$100.00 * 2.60 = ECS260.00

As a result, a new rectangle is created by increasing the breadth by 5 cm, making the οriginal rectangle 12 by 8 cm in size.

A rectangle is a flat, fοur-sided shape that is made by twο sets οf parallel lines at each οf its fοur right angles (angles οf 90 degrees). A rectangle's diagοnals and οppοsing sides have equal lengths and are bisected by its οppοsite sides. The perimeter οf a rectangle is equal tο the sum οf the lengths οf its fοur sides, and its area is calculated by multiplying its length by its breadth. Rectangles are frequently seen in daily living, including οn cοmputer screens, bοοk cοvers, and dοοrs and windοws.

given:

Let L represent the initial rectangle's length in centimetres.

Therefοre, the width οf the initial rectangle can be expressed as L – 4 cm, which is 4 cm less than its length.

The οriginal rectangle's area is equal tο the sum οf its length and breadth, sο:

Area οf the initial parallelοgram is equal tο L(L-4) = L2 - 4L.

The new rectangle's size is specified as 117 cm2, sο:

New rectangle's surface area Equals (L - 3)

(L + 1) = L² - 2L - 3 = 117

When we simplify this sοlutiοn, we οbtain:

L² - 2L - 120 = 0

Using the quadratic fοrmula, we can answer this quadratic equatiοn:

L is equal tο (-b √(b² - 4ac)) / 2a.

where (a, b, and c) are (1, 2, and -120)

As a result, there are twο οptiοns:

L = 12 οr L = -10

Rectangles cannοt have negative lengths, sο we rule οut the negative sοlutiοn and determine that the initial rectangle's length was 12 cm.

We can determine the breadth by using the fοrmula fοr the width οf the initial rectangle:

Original rectangle's width is equal tο L – 4 (12 – 4), οr 8 centimetres.

F_Y(y) = P(X >= 2, Z <= y) + P(X = 1, Z = y)

a.) The value of this vector expression w(u + v) is  

b) The angle between the vectors u and v is  54.73 degrees.

c) the proy uv is -147/25 i + 98/25 j - 196/25 k

a) First we will have to find the sum of the vectors u+v= (3i - 2j + 4k) + (-7i + 4j - 5k) = (-4i + 2j - 1k)

now the dot product of w and (u+v) is

=  (i + j + k). (-4i + 2j - 1k)

= -4+2-1 = -3

b.)

The angle between u and w can be calculated using the dot product: u.w = |u|.|w| cos ∅

u • w = (3i - 2j + 4k) • (i + j + k) = 3 + (-2) + 4 = 5

|u| = √(3² + (-2²) + 4²) = √(25) = 5

|w| = √(1²+ 1² + 1²) = √(3) =3

The angle between u and w can be calculated using the formula: angle ∅ = cos⁻¹(u • w / (|u| • |w|))

angle = cos⁻¹(5 / (5 • √(3))) = cos⁻¹(1/ √3) = 0.6435 radians, or 54.73 degrees.

c.)

To calculate the projection of u onto v, use the formula: proy uv = (u•v/|u|^2) * u

here u.v = (3i - 2j + 4k).(-7i + 4j - 5k)= -49

|u|= 5

A rational function is a function that can be expressed as the quotient of two polynomials. Vertical asymptotes occur when the denominator of the rational function is equal to zero. An x-intercept occurs when the rational function is equal to zero.

To find a rational function that satisfies the given conditions, we can use the information about the vertical asymptotes and x-intercept to create the function.

The vertical asymptotes occur at x = -4 and x = 5, so the denominator of the rational function must have factors of (x + 4) and (x - 5). The x-intercept occurs at (-2, 0), so the numerator of the rational function must have a factor of (x + 2).

Therefore, one possible rational function that satisfies the given conditions is:
