Graph f(x) = 6x^2-11+3 and<br> find the zeroes

babunello [35]

Answer:

x = ±1.155

Step-by-step explanation:

We need to graph the given function $f(x) = 6x^2-11+3$ and find its zeroes.

The attached figure shows the graph of the given function.

To find zeroes,

Put f(x) = 0

So,

$6x^2-11+3=0\\\\x=\pm 1.155$

Hence, this is the required solution.

please help me! What is the approximate value of y? Round to the nearest tenth. A.) 3.1 B.) 3.9 C.) 4.6 D.) 5.4

cluponka [151]

Answer:

Option (C). 4.6 cm

Step-by-step explanation:

In the figure attached,

A right triangle has been given with hypotenuse = 6 cm, leg 1 = x cm, leg 2 = y cm and one angle = 50°

By applying Sine rule in this triangle,

Sin(50)° = $\frac{\text{Opposite side}}{\text{Hypotenuse}}=\frac{\text{Leg 1}}{\text{Hypotenuse}}$

Sin(50)° = $\frac{x}{6}$

x = 6(Sin50°)

x = 4.59

x ≈ 4.6 cm

Therefore, Option (C) will be the answer.
