Answer:

The second one, my order is different, but they are equivalent answers

Step-by-step explanation: 6 22 22 18

(√6 + √11) / (√5 +√3) multiple top and by (√5 - √3) note the minus

(√6 + √11) × (√5 - √3) / (√5 +√3) x (√5 - √3)

(√30 + √55 - √18 - √33) / (5 - 3)

(√30 + √55 - 3√2 - √33) / 2

A man buys lemons at 3 for Rs. 5 and an equal number at 2 for Rs. 4. He mixes them and sells at 5 for Rs. 9. Find his gain or lo

melamori03 [73]

3 lemons cost = Rs. 5

Each lemon cost = Rs. 5/3

2 lemons Cost = Rs. 4

Each lemon cost =

$= \frac{4}{2} = \frac{2}{1} = 2$

Total Cost price of Each lemon =

$\frac{5}{3} + \frac{2}{1}$

LCM = 3

$\frac{5}{3} + \frac{2 \times 3}{1 \times 3} = \frac{6}{3} = \frac{5 + 6}{3} = \frac{11}{3}$

Each lemon Cost =

$= \frac{11}{3} \div \frac{2}{1}$

$= \frac{11}{3} \times \frac{1}{2}$

$= \frac{11}{6}$

Selling price of 5 lemons = 9

Selling price of 1 lemon = 9/5

$loss\% = \frac{loss \times 100}{CP}$

$= \frac{ \frac{4}{6} - \frac{9}{5} \times 100 }{ \frac{11}{6} }$

$= \frac{\frac{55 - 54}{30} \times 100}{ \frac{11}{6} }$

$= \frac{\frac{1}{30} \times 100}{ \frac{11}{6} }$

$= \frac{100}{30} \times \frac{6}{11}$

$= \frac{20}{1} = 1 \frac{9}{11} \% \: loss$

Over which interval is the graph of f(x) = –x2 + 3x + 8 increasing? (–∞, 1.5) (–∞, 10.25) (1.5, ∞) (10.25, ∞)

Vadim26 [7]

F(x) = -x^2 + 3x + 8
f'(x) = -2x + 3

when f(x) is increasing f'(x) > 0

-2x + 3 > 0

-2x > -3

x < 3/2 or 1.5

So the required interval is (-infinity,1.5).The first choice.

Rewrite the given parametric equations in Cartesian from x(t) = 2t– 1 y(t) = 5t

docker41 [41]

Hi there!

$\large\boxed{(-\frac{5}{3},-\frac{5}{3})}$

We can begin by setting the two expressions equal to solve for t:

2t - 1 = 5t

Subtract 2t from both sides:

-1 = 3t

Divide both sides by 3:

t = -1/3

Plug in this value of t into x(t) and y(t):

x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3

y(-1/3) = 5(-1/3) = -5/3

Thus:

(-5/3, -5/3) are the corresponding coordinates.
