Solve √(3x+7)+2√(x-8)=0.

Mathematics
1 answer:
laiz [17]3 years ago
4 0

Answer:

The solution to this question is 39

Step-by-step explanation:

Given that :

√(3x+7)+2√(x-8)=0.    

√(3x+7)=-2√(x-8)           (i)

square of the equation (i)

Then

(√(3x+7))^2=(-2√(x-8))^2

we know that √a*√a=(√a)^2=a So,

(3x+7)=4(x-8)      

3x+7=4x-32        //multiply by 4

32+7=4x-3x  exchange the value.

39=1x

x=39.

Firstly we need to realize that "sea level" is the same as "surface of the ocean" and 0.

It means that Trina the scuba-diver is closer to the surface of the ocean than Jessie the glider because Trina is 85,5 meters from 0 level and Jessie is 87,9 meters from 0 level.

Now if Trina will hang glide at the altitude of 85,5, than she will <em>not </em>fly higher than Jessie (she will fly lower by 87,9 - 85,5 = 2,4 meters).

18. Water is stored in a cylindrical tank with a diameter of 36 feet. The surface
Sidana [21]

Answer:

h = 21 feet

Step-by-step explanation:

surface area = 2 (pi) r^2 + (pi) × d × h

=(2 × (pi) × 18) + ((pi) × 36 × h)

=72(pi) × h

226.194671059 × h = 4750.1

h = 21 feet

Scilla [17]
<span>Benford’s law states that the probability that a number in a set has a given leading digit, d, is
P(d) = log(d + 1) - log(d)</span>  
The division property of logarithm should be use to make it as a single logarithm  
P(d) = log ( (d + 1)/ d)  
So the probability that the number 1 is the leading digit is
P(1) = log ( ( 1+1)/ 1)
P(1) = log ( 2)
<span>P(1) = 0.301</span>
