The minimum is the y-value of the vertex and the axis of symmetry is the x-value of the vertex. Next finding the function is this y=x^2-3x+2 because 2 is the y-intercept, the x^2 make the graph make a u-shape, and -3x make the graph moves diagonally 3 units down and right.

Mercury is the closest planet to the sun at a distance of 36 million miles. The closest star to the sun is Proxima Centauri, whi

SpyIntel [72]

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles

∠B = 77°, a = 7.42 and b = 12.61

Solution:

Given triangle ABC.

∠A = 35°, ∠C = 68°, c = 12

To find the measure of ∠B:

Sum of all the angles of the triangle = 180°

⇒ ∠A + ∠B + ∠C = 180°

⇒ 35° + ∠B + 68° = 180°

⇒ 103° + ∠B = 180°

⇒ ∠B = 180° – 103°

⇒ ∠B = 77°

To find the length of a and b:

The side opposite to angle A is a.

The side opposite to angle B is b.

Using law of sine,

$$\frac{\sin C}{c}=\frac{\sin A}{a}$

$$\frac{\sin 68^\circ}{12}=\frac{\sin 35^\circ}{a}$

$$\frac{0.9271}{12}=\frac{0.57357}{a}$

Do cross multiplication, we get

$$0.9271a=6.88284$

Divide by 0.9271 on both sides, we get

⇒ a = 7.42

Again by law of sine,

$$\frac{\sin C}{c}=\frac{\sin B}{b}$

$$\frac{\sin 68^\circ}{12}=\frac{\sin 77^\circ}{b}$

$$\frac{0.9271}{12}=\frac{0.9744}{b}$

Do cross multiplication, we get

$$0.9271b=11.6928$

Divide by 0.9271 on both sides, we get

⇒ b = 12.61

Hence ∠B = 77°, a = 7.42 and b = 12.61.
