Answer:

Step-by-step explanation:

Given

$y = \frac{1}{6}x + 60$

Required

Interpret the slope and y intercept

The general form of an equation is:

$y = mx + b$

Where

$m=slope$

$b = y\ intercept$

By comparison

$m = \frac{1}{6}$

$b = 60$

Interpretation:

Slope represents rate and y intercept represents the number of chirps at time 0.

So, the interpretations are:

Slope: The cricket chirps at a rate of $\frac{1}{6}$ chirps per minute

y intercept: The initial number of chirps is 60

h(t)=-5t^2+10t+3 is the height of a diver above the water, t seconds after the diver leaves the springboard. How high above the

Kobotan [32]

Answer:

3 units

Step-by-step explanation:

So if we want to know how high the spring board is, this will need to be the time at which the diver is still at the top of the board, in this case t = 0 seconds.

So we will need to find h(0)

h(0) = 5(0)² + 10(0) + 3 = 0 + 0 + 3 = 3

4.) Fill in the table to show a proportional relationship and then identify the

Answer/Step-by-step explanation:

✔️Number of Yoga classes = x

Cost ($) = y

Constant of proportionality (k) = y/x

Using the pair form the table of values given, (4, 60), find the constant of proportionality:

✅k = 60/4 = 15

Equation that represents the relationship between x and y is:

y = 15x

✔️Let's complete the table.

✅When number of yoga classes (x) = 2:

Substitute x = 2 into y = 15x

Thus,

y = 15*2 = 30

That is, 2 Yoga classes will cost $30

✅When number of yoga classes (x) = 6:

Substitute x = 6 into y = 15x

Thus,

y = 15*6 = 90

That is, 6 Yoga classes will cost $90

✅When number of yoga classes (x) = 8:

Substitute x = 8 into y = 15x

Thus,

y = 15*8 = 30

That is, 8 Yoga classes will cost $120
