Answer:

None of the options are correct

Step-by-step explanation:

Given

f(q) = q^2 - 125

Required

The roots of the function

Since the function is a quadratic function; to get the roots of the function, f(q) must be equal to 0

f(q) = q^2 - 125 becomes

0 = q^2 - 125

Make q^2 the subject of formula

125= q^2

Rearrange

q^2 = 125

Take square roots of both sides

\sqrt{q^2}  = \sqrt{125}

q  = \sqrt{125}

Expand the square root of 125

q  = \sqrt{25 * 5}

q  = \sqrt{25} * \sqrt{5}

q = ±5 * \sqrt{5}

Split into 2

q  = 5 * \sqrt{5} or q  = -5 * \sqrt{5}

q  = 5  \sqrt{5} or q  = -5 \sqrt{5}

Hence, the roots of the quadratic function are q  = 5  \sqrt{5} or q  = -5 \sqrt{5}

The area of the square adjacent to two sides of a right triangle are 29.25 square units and 13 units 30 POINTS
Otrada [13]

Answer:

x=6.5\ units

Step-by-step explanation:

step 1

Find the length side of the smaller square

The area of the square is equal to

A=a^{2}

so

a^{2}=13

a=\sqrt{13}\ units

step 2

Find the length side of the larger square

The area of the square is equal to

A=b^{2}

so

b^{2}=29.25

b=\sqrt{29.25}\ units

step 3

Find the value of x

Applying the Pythagoras Theorem

x^{2} =a^{2}+b^{2}

substitute the values

x^{2} =13+29.25

x^{2} =42.25

x=6.5\ units
