<span>Question 1
</span>I believe the simplest way to write this would be 37/800. I got this by simply putting 4 5/8 over 100.

Question 2
The correct answer here is 44.8 becasue if you multiply 80 by .56 (to represent 56/100 or 56%) you get 44.8.

EASY POINTS Find the domain of the graphed function.

Vladimir [108]

Using it's concept, it is found that the domain of the graphed function is given as follows:

D. $-4 \leq x \leq 2$

<h3>What is the domain of a function?</h3>

It is the set that contains all possible input values for the function. In a graph, it is given by the values of x.

In this graph, x assumes values between -4 and 2, inclusive due to the closed circle, hence the domain is given by:

D. $-4 \leq x \leq 2$

Where does the line y=x-1 cross the y-axis?

konstantin123 [22]

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ It would cross at (0, -1) or just -1

y = mx + c

The 'c' value in the equation is the y intercept

Can someone pls help me with this !

Using a line of best fit, the predicted tsunami speed for the following depths is given by:

a. 1151 km/h.

b. 572 km/h.

c. 130 km/h.

d. 122 km/h.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (depth, velocity) are given by:

(7000, 943), (4000, 713), (2000, 504), (200, 159), (50, 79), (10,36)

Inserting these points in the calculator, the velocity in function of the depth is:

v(d) = 0.12879d + 121.03448

Hence, the velocities are given as follows:

a. v(8000) = 0.12879 x 8000 + 121.03448 = 1151 km/h.

b. v(3500) = 0.12879 x 3500 + 121.03448 = 572 km/h.

c. v(70) = 0.12879 x 70 + 121.03448 = 130 km/h.

d. v(5) = 0.12879 x 5 + 121.03448 = 122 km/h.
