What is the domain and range of f(x)=23+15x^2

1 answer:

Andreyy893 years ago

4 0

Domain: all real numbers, since no number can make this function undefined
Range: since this an upward opening parabola(because the quadratic coefficient is positive), and the minimum point is 23, the range is going to be any number equal or greater than 23.

Answer:

I'm telling you once in my life, I committed mistake and I'M NOT POINT STEALER. put that in mind. You hurt me.

Let's solve for x.

2x+3y=5

Step 1: Add -3y to both sides.

2x+3y+−3y=5+−3y

2x=−3y+5

Step 2: Divide both sides by 2.

The ratio of the measures of the three angles is 4:5:6. Find the measure of each angle of the triangle

Furkat [3]

Answer:

Let the number be x.

Given the statement: The ratio of the measure of the three angles is, 4 : 5 : 6.

Then, the angles be 4x , 5x and 6x respectively.

We know that: The sum of all the measures of angles is 180 degree.

then;

$4x+5x+6x = 180^{\circ}$

Combine like terms;

$15x = 180^{\circ}$

Divide by 15 both sides we get;

$x = 12$

Then, the measure of each angle of triangle:

$4x = 4(12) = 48^{\circ}$

$5x = 5(12) = 60^{\circ}$

$6x = 6(12) = 72^{\circ}$
