To test whether an integer, $n$, is prime, it is enough to be sure that none of the primes less than or equal to the square root
IrinaK [193]

Answer:

the largest divisor is less than the square root of that number

Step-by-step explanation:

Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61

So divide 937 with all the primes less  than 30.61

937/2, 937/3, 937/5,...................937/29

29 would be the largest divisor which is less than the square root of 937 .

29< 30.61

But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.

If any number such 925 is chosen and it gets divided wholly by another prime like 5

925 /5= 185  so it is not a prime number

Find the equation of the line. <br> Please need help badly!!
hoa [83]

Answer:

lets consider two end points are the marked points ,

Then ,

(1,5)=x1,y1

(-1,-3)=x2,y2

line passes through point(1,0)=x3,y3

slope of line ,m = (y2-y1)/(x2-x1)

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

=4

Eqn of line is:

y-y3=m(x-x3)

y-0 = 4(x-1)

y=4x-4

4x-y=4 is reqyuired eqn..

Step-by-step explanation:

Problem may arise due to calculation but plz check it ...

A future value?
P present value 300
R interest rate 0.013
k compounded monthly 12
T time 10 years
A=300×(1+0.013÷12)^(12×10)
A=341.62

Which is the best approximation for the measure of angle ABC?
ankoles [38]
We can find the approximate measurement of angle ABC  and it is equal to 180°. The summation of all angles in a triangle is 180°.
Solving for x or angle B, we need to used Pythagorean theorem and SOH CAH TOA.
Solving for angle A:
sinA = 10.5/20
A = 31.67°

Solving for angle B:
180° = ∠C + ∠B + ∠A
180° = 90° + ∠B + 31.67
∠B = 58.33°

The x value is 58.33°.
