Answer:
Y intercept is the value of y when x is equaled 0.
Step-by-step explanation:
Slope intercept form is
y = mx + b
In this equation, b is the y intercept.
Given the equation :

Let: y = sin x
So,

the given equation will be:

Solve for y, take 3y as a common:

so,

Note: the range of sine function is [ -1, 1]
So, sin x = 2 ( is rejected)
So, the answer will be: x ={ 0 , pi }
Think of a vertical number line. The positive values count down as we move down this number line. The negative numbers count up, so to speak, as we move down the number line. So we have -1, -2, -3, ... as we move down. This indicates that -5 is <u>not</u> smaller than -7.

Step-by-step explanation:
Answer:
0.25feet
Step-by-step explanation:
The equation is not well written. Let the equation of the height be modelled as;
h = -16d²+8d+4
The velocity of the ball is zero at its maximum height.
Velocity = change in displacement/time
v = dh/dd
Differentiate
v = -32d+8
Since dh/dd = v = 0
0 = -32d+8
Add 32d to both sides
0+32d = 8
32d = 8
Divide both sides by 32
32d/32 = 8/32
d = 1/4
d = 0.25feet
Hence the maximum height of the tennis ball is 0.25feet
Note that the modeled equation was assumed. You can apply the same calculation to any equation given
