Answer:

5/3 = -3/5: 5/3 = -3/5 · 3/5 = -3 · 3/5 · 5 = -9/25 (-0.36)

Step-by-step explanation:

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction.

The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/3 is 3/5) of the second fraction.

Next, multiply the two numerators.

Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling. In other words - three fifths divided by five thirds = (negative) nine twenty-fifths.

Evaluate f(9) given the function f(x)=3x2 – 11x - 21*

Blizzard [7]

Answer:

123

Step-by-step explanation:

The given function is :

$f(x)=3x^2 - 11x - 21$

We need to find the value of f(9). It can be done by putting x = 9 in the above function as follows :

$f(9)=3(9)^2 - 11(9) - 21\\\\=243-99-21\\\\=123$

So, the value of f(9) is 123.

A student inscribes a triangle within a semicircle. What is the measure of ∠XYZ?

Dmitry [639]

Answer:

The correct answer is option A. 90°

Step-by-step explanation:

Points to remember

Measure of angles on the semicircle is 90°

From the figure we can see a semicircle and a triangle inscribes on it.

To find the measure of <XYZ

Here <XYZ is on the semicircle that is angle XYZ is a right angle.

Therefore m<XYZ = 90°

The correct answer is option A. 90°

Find the smallest value of $x$ such that $x^2 + 10x + 25 = 8$.

Mashutka [201]

Answer:

-5 -√8 or ≈ -7.83

Step-by-step explanation:

Solving the quadratic equation, to find its roots:

x^2 + 10x + 25 = 8 ⇒ The left side is perfect square
(x+5)^2=8 ⇒ Getting square root of both sides
x+5 = ± √8 ⇒ There are 2 roots
x = - 5 ± √8

The smallest root is:

x= -5 - √8 ≈ -7.83
