If x+7 ,x+11 , 19+x are in successive proportion then x =​

Answer»

*Question:

If x+7 ,x+11 , 19+x are in successive proportion then x =

*Answer:

x+7 , 11+x , 19+x are in successive proportion.

So,

→ (11 + x)/(x + 7) = (19 + x)/(11 + x)

→ 121 + 22x + x × x = 133 + 26X + x × x

4X = -12

→ x = -3

Hence our answer is -3

Find the nature of the given quadratic equation 7x2+2x+1=0​

Answer»

Answer:

Roots are not real

Step-by-step explanation:

7x^2 + 2x+ 1 = <klux>0</klux>\\

Comparing with STANDARD quadratic equation ax^2 + bx+c we get

a= 7

b=2

c=1

Discriminant = b^2-4ac

2^2 - 4(7)(1)

4-28\\-24

-24 < 0

Therefore roots are not real

1. Why does a desert cooler cool better on a hot dry day?​

Answer»

Step-by-step explanation:

On a dry day, WATER vapor present in the air will be less, and the circulation of this air will provide faster cooling COMPARED to a HUMID day. Humid air contains more water vapor content so energy transferred will be less and the rate of cooling will be less. Therefore desert COOLER cools better on a hot dry day.

Find the value of x if, 7^x-3 multiply by 3 ^2x-8 =441​

Answer»

      \underline{\bold{Answer:}}

      5

      \underline{\bold{Step-by-step-explaination:}}

      \text{The given function is }7^{x-3}*3^{2x-8} = 441

      \text{Let us start by finding the prime factors of }441

\implies \boxed{441 = 7*7*3*3}

\implies \boxed{441 = 7^{2} * 3^{2} }

      \text{Now substituting the value in the function}

\implies \boxed{7^{x-3}*3^{2x-8} = 7^{2} * 3^{2}}

      \text{Now comparing the values of the exponents}

\implies \boxed{x-3 = 2}

\implies \boxed{x = 5}

      \text{We can check whether our answer is correct by putting it in } 2x-8 = 2

\implies \boxed{2x-8 = 2}

\implies \boxed{2(5)-8 = 2}

\implies \boxed{10-8 = 2}

\implies \boxed{2 = 2}

 \therefore \text{ The value of }x \text{ in }7^{x-3}*3^{2x-8} = 441 \text{ is }5
