\sqrt 676 =26

hjlf3 years ago
5 0

So, if you are multiplying the two radicals (numbers under a root, like a square root), you can put both under the same square root. Like this, the square root of 13 times square root of 52 is the same as the square root of 13 times 52. So the answer is actually the square root of 676, and that is 26.

While painting the side of his house, Jason positioned his ladder so that the top was 16 feet
kenny6666 [7]

Answer: 8.71\ ft

Step-by-step explanation:

Given

Ladder is 16 ft from bottom and 12 away from the base of the wall

In another case ladder is 18 ft above the ground and let say x ft away from the base of the wall

In both the cases the length of ladder remains the same

Using Pythagoras theorem, we can write

\Rightarrow 16^2+12^2=L^2\ldots(i)\\\Rightarrow 18^2+x^2=L^2\ldots(ii)\\\text{From (i) and (ii)}\\\Rightarrow 16^2+12^2=18^2+x^2\\\Rightarrow x^2=256+144-324\\\Rightarrow x^2=76\\\Rightarrow x=\sqrt{76}\\\Rightarrow x=8.71\ ft

We know that Zoey can tile 1.25 square yards in 20 minutes (which is 1/3 of an hour) so we wanna see how much she can tile in an hour. Multiply 1.25 by 3.

1.25•3= 3.75 or 3 3/4

Consider the quadratic function f(y) = 8y2 – 7y + 6. What is the constant of the function?
olga55 [171]

For this case we have the following expression:

f (y) = 8y ^ 2 - 7y + 6

we observe that we have a polynomial of the second degree.

The constant term of the polynomial, is that coefficient that is not written accompanying a variable.

We have then that the constant term of the quadratic function is:

6

Answer:

the constant of the function is:

6
