If Alfa and beta are the zeroes of the quadratic polynomial f(x) = kx² + 4x + 4 such that Alfa² + beta² = 24 find the value of k

Answer» LET ALPHA =a and beta=b
a+b= -4/k and AB= 4/k
a^2+b^2=[(a+b)^2-2ab]
24=16/k^2 - 8/k
3=2/k^2 - 1/k
3k^2+k-2=0
(3k-2)(k+1)=0
k = 2/3 or -1
5.

The denominator of a rational number greater than its numerator by 8 if numerator is increased by 17and denominatior is decreased by 1 the number obtained is 3/2 the rational number is?

Answer»

Let the rational no be x / y

y = x + 8

-x + y = 8 eq1

(x + 17) / (y - 1) = 3 / 2

2 (x + 17) = 3 (y - 1)

2x + 34 = 3y - 3

2x - 3y = -37 eq2

Multiply eq 1 by 2 we get

-2x + 2y = 16
2x -3y = -37

- y = -21

y = 21

Put y in eq. 2

2x - 3×21 = -37

2x = -37 + 63

x = 26

Rational no is = x/y = 21/26

a mobile phone was marked at 35% above the cost price and a discount of 20% was given on the marked price find the profit it % or loss % made by the shopkeeper

Answer»

Let the cost price be ₹100
then,
marked price = 100 + 35% of 100
=>₹135

now,
discount % = 20%
so, discount allowed,
=>20/100 ×135 = ₹23

so,
selling price = 135-23
=>₹112

profit = 112-100 =₹12

therefore, PERCENT profit,
12/100 *100 = 12%

hope it HELPS u...
if yes, mark brainliest...

The sides of a triangular field are 41m,40m and 9m.Find the number of rose beds that can be prepared in the field if each rose bed in an average requires 900cm square of space

Answer»

By HERON's FORMULA. Area of a triangular= √s×(s-a)(s-b)(s-C) ,where a,b,c are sides of the triangle and s is the semi perimeter. so, area of the field=√[45×(45-41)(45-40)(45-9)] = √(45 × 4 × 5 × 36) = √32400 = 180m^2 =1800000cm^2. now, space needed for a flower BED = 900cm^2. so, number of flower beds = 1800000/900 = 2000.

If cos ∅ - sin ∅ =√2 sin∅, prove that cos ∅ + sin∅ =√2 cos∅

Answer»

Here I am WRITING Ф as A because it is difficult for me to WRITE Ф Always.

Given : cos A - sin A =  (\sqrt{2} sin A)

On SQUARING both sides, we get

(cos A - sin A)^2 = ( \sqrt{2} sin A)^2

cos^2A+ sin^2A - 2sinAcosA = 2sin^2 A

cos^2A = sin^2A + 2sinAcosA

Add cos^2A on both sides, we get

cos^2 A + cos^2A = sin^2A + cos^2A + 2sinAcosA

2cos^2A = (cosA+sinA)^2

\sqrt{2} cos A = (cos A + sin A)

In how much time will a certain sum be 1.5 times the principal at 10% per annum ?

Answer»

Hi
let the principal (P)=rs x
rate of INTEREST per year= r=10
Amount= A =1.5 of principal
A=rs 1.5 x
time =T
we know that
A =P(11 +RT/100)
now substitute the given values
1.5=x(1+10xT/100)
15x/10=x(1+T/10)
15x/10=x/10x(10+T)
=15 x/10) x (10/x)=10+T
15=10+T= 15-10=T
therefore
(5=T) = T= 5 years

I6f 45kg 450 gm of sugar equally distribute among 15 persons how much shall each get

Answer»

Given :

45 kg 450 gm of sugar be equally DISTRIBUTED among 15 people

To Find :

Each one's share.

Solution :

Let's change Kilograms to GRAMS :

So,

  • 1 kg = 1000 g

45 kg = 45 x 1000

45 kg = 45000 grams.

As given,

Total QUANTITY of Sugar :

45000 g + 450 g

→ 45450 grams.

Finding Each One's Share :

15 people = 45450 grams sugar

1 person = 45450÷15

1 person = 3030 grams.

3030 grams = 3030÷1000

3030 grams = 3.03 kg.

Hence,

Hence, Each person will get 3.03 kg of sugar.

A two digit no. is 4 times the sum of its digits and twice the productof its digits .Find the numberPls don't spam answer..Pls give me ryt answer I have doubt on my equation..Pls help me ☺️

Answer»

Let the digit in the ones PLACE be x and tens place be y
Hence the two digit number = 10y + x
Given that the two digit number = 4 TIMES SUM of its digits
⇒ 10y + x = 4(x + y)
⇒ 10y + x = 4x + 4y
⇒ 3x – 6Y = 0
⇒ 3x = 6y
∴ x = 2y → (1)
It is also given that the two digit number = 2 times product of its digits
⇒ 10y + x = 2xy
Divide by xy both the sides, we get
∴ y = 3
Hence x = 6
The two digit number is (10y + x) = 10(3) + 6 = 36

The Marketed Price of an gift item is Rs.176 and sold it for Rs.165. Find the discount percent.

Answer»

ANSWER:

Discount % = 6.25%

Step-by-step explanation:

Marked PRICE of the GIFT item = 176 rs

Selling price of the gift item = 165 rs

Discount = marked price - selling price

Discount = 176 - 165

Discount = 11 rupees

The shopkeeper PROVIDED a discount of 11 rupees on the gift item

Discount % = discount/marked price × 100

Discount % = 11/176 × 100

Discount % = 25/4

Discount % = 6.25%

Discount % = 6.25%

Gauss NOTICED that if he was to split the numbers into two GROUPS (1 to 50 and 51 to 100), he could ADD them TOGETHER vertically to get a sum of 101. Gauss realized then that his final totalwould be 50(101) = 5050.
