Answer:

$\huge\boxed{3.873}$

Step-by-step explanation:

Note that the squares are on the sides of these triangles are on the hypotenuse/one leg.

We know that the area of a square is $l^2$ where l is the length. Since we know the area, we can find the square root of the area to find the side length.

So the side lengths are $\sqrt{25}$ and $\sqrt{10}$ .

Since we know the hypotenuse is $\sqrt{25}$ and one of the legs is $\sqrt{10}$ , we can use the Pythagorean Theorem to find the missing side.

The Pythagorean Theorem states that $a^2 + b^2 = c^2$ , where c is the hypotenuse and a/b are the legs.

We know the hypotenuse and a leg, so we can substitute inside

$a^2 + \sqrt{10}^2 = \sqrt{25}^2$

Squaring a square root is the same as doing nothing.

$a^2 + 10 = 25\\\\a^2 = 25-10\\\\a^2 = 15\\\\a = \sqrt{15}\\\\a \approx 3.873$

Hope this helped!

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

Answer:

1.38 to the nearest hundredth.

Step-by-step explanation:

Dividing:

x + 1 ) 3x - 1 ( 3

3x + 3

-4

so (3x - 1) / (x + 1) = 3 - 4 / x+ 1

Integral of (3 - 4 / x+1 ) = 3x - 4 ln(x + 1)

Between limits of 1 and 2 we have:

(3(2) - 4 ln 3) - (3 - 4 ln2)

= 1.6056 - 0.2274

= 1.3782.

Answer:

y>0.5

Step-by-step explanation:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>

Shade above the line for a "greater than" (y> or y≥)

or below the line for a "less than" (y< or y≤).

y+x>1

-y -y

x>1-y

2x+y<3

-y -y

2x<3-y

divide by 2

x<1.5-y/2

1.5-y/2>1-y

-1.5+y -1.5+y

y>0.5
