Answer:

c = 26

Step-by-step explanation:

This is a right triangle, so we can use the Pythagorean theorem.

a^2 + b^2 = c^2

where a and b are the legs and c is the hypotenuse

10^2 + 24^2 = c^2

100 + 576 = c^2

676 = c^2

Take the square root of each side

sqrt(676) = sqrt(c^2)

26 = c

Y is inversley proportionaly to x. when y=7, x=9

mrs_skeptik [129]

The equation is y = 63/x

And y = 3 when x=21

Step-by-step explanation:

When y varies inversely with x, The inverse proportion is given by:

y ∝1/x

When the proportionality symbol is removed, a constant of proportionality is introduced

$y = \frac{k}{x}$

Putting y = 7 and x = 9

$7 = \frac{k}{9}\\k = 9*7\\k = 63$

So,

$y = \frac{63}{x}$

Putting x =21

$y = \frac{63}{21}\\y = 3$

Hence,

The equation is y = 63/x

And y = 3 when x=21

Which expression is equivalent to the pic

finlep [7]

Answer:

OPTION A: $\frac{1}{2^{15}}$

Step-by-step explanation:

We should know that:

$(a^b)^c = a^{b . c}$

So, $(2^3)^{-5} = 2^{3 . (-5)}}$

$= 2^{-15}$

This is equivalent to $\frac{1}{2^{15}}$

Hence, OPTION A is the answer.
