1. The linear equation y = 3x tells us that this line is going to be more vertical or horizontal? Explain.
vodka [1.7K]
More vertical. 
y=x, where the slope is 1, is a line that forms a 45 degree angle with the positive part of the x axis. y=3x has a bigger slope, so it is going to rise 3 times faster than y=x so the line is more vertical
I hope that makes sense.

A sinusoidal function whose period is 1/2, maximum value is 10, and minimum value is -4, has a y-intercept of 3. What is the equ
nikdorinn [45]
Period of sin wave = 1/2
Period of parent sine function is 2π.

This means the x value of sine function (sin(x)) has to be divided by 4π to get a period of 1/2 because 2π/4π = 1/2

Thus, our function will be of the form: sin( \frac{x}{4 \pi })

Maximum Value = 10 
Minimum Value = -4

Amplitude of the function = (Maximum Value - Minimum Value)/2
So, amplitude of the function is 7 

Thus, the function will be of the form:

7sin( \frac{x}{4 \pi } )

The function has a y-intercept other than zero, this means the function will be of the form:

y=7sin( \frac{x}{4 \pi } )+k

The y-intercept is 3. This means for x=0, y=3. Using the values, we get:

3=7sin(0)+k \\  \\ 
3=k

Thus the equation of the sinusoidal function becomes:

y=7sin( \frac{x}{4 \pi } )+3

what is the sum of the measures of the angles of a convex quadrilateral? will this property hold if the quadrilateral is not con
bonufazy [111]

Answer:

The sum of the measures of the angles of a convex quadrilateral is 360° as a convex quadrilateral is made of two triangles. Yes, this property also holds true for a quadrilateral which is not convex. This is because any quadrilateral can be divided into two triangles.
