If Z varies directly as y and inversely as square root of x and z = 5, when y =3,x=9. Find the value of z when y=18 and x = 25.

Pani-rosa [81]

Answer:

<h2>18</h2>

Step-by-step explanation:

$z \alpha y \\z\alpha \frac{1}{\sqrt{x} } \\z \alpha \frac{y}{\sqrt{x} } \\z = \frac{ky}{\sqrt{x} } -------(1)\\\\5 = \frac{3k}{\sqrt{9} } \\ 5 = \frac{3k}{3} \\3k = 15\\k = 15/3\\k = 5\\Substitute 5 for k in eq 1\\z = \frac{5y}{\sqrt{x} }\\ z=?\\ y=18 \\ x = 25.\\z = \frac{5y}{\sqrt{x} }\\z = \frac{5(18)}{\sqrt{25} }\\z= \frac{90}{5} \\z = 18$

What is the length of ef in the right triangle below?

KonstantinChe [14]

Answer:

24

Step-by-step explanation:

You're given a side and a hypotenuse in a right triangle, so you're able to use the Pythagorean Theorem.

$a^{2} + b^{2} = c^{2}\\\\a^{2} + (7)^{2} = (25)^{2}\\$

Now isolate a on one side and solve for a.

$\\a^{2} = (25)^{2} - (7)^{2}\\\\a = \sqrt{(25)^{2} - (7)^{2}} \\\\a = 24$
