Answer» ANSWER: SUM : -10 product: -24 b =10 Step-by-step explanation: the equation will be x^2 - ( sum of roots)x + product of roots so equation is = x^2-(-10)x +(-24) =x^2 + 10x- 24 b= 10 sum= -4-6= -10 product= -6*-4= 24 hope it helps you plz mark it as BRAINLIEST!!

18551.

1.The two zeroes of a quadratic polynomial are -4 and -6. Find the sum and product of the zeroes. What is the value of coefficient b?

Answer»

ANSWER:

SUM : -10

product: -24

b =10

Step-by-step explanation:

the equation will be

x^2 - ( sum of roots)x + product of roots

so equation is = x^2-(-10)x +(-24)

=x^2 + 10x- 24

b= 10

sum= -4-6= -10

product= -6*-4= 24

18555.	How many positive integers n are there such that 450 divided by n leaves a remainder of 30?
Answer» I'm assuming the question is meant to read: 10n≤n10 Python TELLS us: >>> [n for n in RANGE(1,100) if 10n <= n10] [2, 3, 4, 5, 6, 7, 8, 9,10] >>> LEN([n for n in range(1,100) if 10n <= n10]) 9 But to actually think it out without Python-bashing: 1 doesn't grow from exponents, so 110 won't be bigger than 101 . We start at n=2 . On the positive integers, both sides are strictly INCREASING, and we know the left side of the equation grows strictly faster than the right side, so once the left side is greater, it will remain greater. At n=10 , we get 1010≤1010 .

How many positive integers n are there such that 450 divided by n leaves a remainder of 30?

Answer»

I'm assuming the question is meant to read:

10n≤n10

Python TELLS us:

>>> [n for n in RANGE(1,100) if 10**n <= n**10]

[2, 3, 4, 5, 6, 7, 8, 9,10]

>>> LEN([n for n in range(1,100) if 10**n <= n**10])

9

But to actually think it out without Python-bashing:

1 doesn't grow from exponents, so 110 won't be bigger than 101 . We start at n=2 .

On the positive integers, both sides are strictly INCREASING, and we know the left side of the equation grows strictly faster than the right side, so once the left side is greater, it will remain greater.

At n=10 , we get 1010≤1010 .

18560.

Please help ! Trigonometry question.

Answer»

Answer:

HI here's your answer

Step-by-step explanation:

$\frac{1+tan^{2}A }{1+cot^{2} A}$

as $tan^{2} A = \frac{sin^{2}A }{cos^{2}A }$

and $cot^{2} A = \frac{cos^{2}A }{sin^{2}A }$

LET substitute the values in the initial equation we GET,

$\frac{1+\frac{sin^{2}A }{cos^{2}A } }{1+\frac{cos^{2} A}{sin^{2} A} }$

by solving the above we get,

$\frac{\frac{cos^{2}A+sin^{2}A }{cos^{2} A} }{\frac{sin^{2}A+cos^{2} A }{sin^{2} A} }$

as $sin^{2}A+cos^{2} A=1$

substituting the value in the above equation we get,

$\frac{\frac{1}{cos^{2}A } }{\frac{1}{sin^{2} A} }$

which can be simplified as ,

$\frac{sin^{2} A}{cos^{2} A}$

which is,

$tan^{2}A$

Answer» Given : The population of a particular town 4 YEARS back was 2,500. The current population is 4,000. the rate of growth of the population has been kept CONSTANT and it has been compounded annually To find : What will be the population after a period of 4 years Solution: Let say rate of growth = r % per ANNUM A = P(1 + r/100)ⁿ as rate of growth of the population has been kept constant and it has been compounded annually Population 4 years back = 2500 Time period n = 4 years Current population = 2500 ( 1 + r/100)⁴ => 4000 = 2500 ( 1 + r/100)⁴ => ( 1 + r/100)⁴ = 1.6 Current population = 4000 Population after 4 years = 4000 ( 1 + r/100)⁴ Substitute ( 1 + r/100)⁴ = 1.6 => Population after 4 years = 4000 * 1.6 => Population after 4 years = 6400 population after a period of 4 years = 6400 Learn more: Q2.

The population of a particular town 4 years back was 2,500. The current populationis 4,000.What will be the population after a period of 4 years, if the rate of growth of thepopulation has been kept constant and it has been compounded annually?

Answer»

Given : The population of a particular town 4 YEARS back was 2,500. The current population is 4,000. the rate of growth of the population has been kept CONSTANT and it has been compounded annually

To find : What will be the population after a period of 4 years

Solution:

Let say rate of growth = r % per ANNUM

A = P(1 + r/100)ⁿ as rate of growth of the population has been kept constant and it has been compounded annually

Population 4 years back = 2500

Time period n = 4 years

Current population = 2500 ( 1 + r/100)⁴

=> 4000 = 2500 ( 1 + r/100)⁴

=> ( 1 + r/100)⁴ = 1.6

Current population = 4000

Population after 4 years = 4000 ( 1 + r/100)⁴

Substitute ( 1 + r/100)⁴ = 1.6

=> Population after 4 years = 4000 * 1.6

=> Population after 4 years = 6400

population after a period of 4 years = 6400

18566.

Prove that the following are irrationals (i) 7√5 (ii) 6+√2

Answer»

Answer:

HOPE IT HELPS

Step-by-step explanation:

i)let us ASSUME THAT 7√5 is rational if possible

Then clearly

7√5= p/q [ q≠0 and p and q are co-prime ]

=> √5= p/7q

if p/q is rational then p/7q is also rational EVENTUALLY √5 is rational

But √5 is irrational

HENCE we arrive at contradictions

Therefore 7√5 is irrational

ii) Let us ASSUME THAT 6+√2 is rational if possible

Then Clearly

6+√2=p/q [ q≠0 and p and q are co-prime ]

=> √2= p/q - 6

Now if p/q is rational then p/q-6 is also rational, eventually √2 is rational

But √2 is irrational

Hence, we arrive at contradictions

Therefore, 6+√2 is irrational

[ proved (i) and (ii)]

ANSWER

Let H= height of SECOND tower, d=distance between TWO towers

height of first tower = 30 m

From given data,

$\frac{30}{d }= tan60 = \sqrt{3}$

$\frac{h}{d} = tan30 = \frac{1}{ \sqrt{3} }$

$\sqrt{3} h = d$

$30 = d \sqrt{3}$

$h = 10m$

$d = 10 \sqrt{3}m$

THEREFORE, height of the other tower is 10 m.

18583.	Do the equations 2x + 4y = 3 and 12x + 6y = 6 represent a pair of parallel lines? Justify your answer.
Answer» No, the equations 2x + 4y = 3 and 12x + 6y = 6 don't REPRESENT a pair of PARALLEL lines because the SLOPE of both the lines are not equal. Slope of 2x + 4y = 3 => -2/4 = -1/2 Slope of 12x + 6y = 6 => -12/6 = -2 6( 2x + y)=6. 2x + y = 1 Mark it brainliest ♥️.

Do the equations 2x + 4y = 3 and 12x + 6y = 6 represent a pair of parallel lines? Justify your answer.

Answer»

No, the equations 2x + 4y = 3 and 12x + 6y = 6 don't REPRESENT a pair of PARALLEL lines because the SLOPE of both the lines are not equal.

Slope of 2x + 4y = 3 => -2/4 = -1/2

Slope of 12x + 6y = 6 => -12/6 = -2

6( 2x + y)=6.

2x + y = 1
