Mathematics
1 answer:
devlian [24]3 years ago

Answer:

Step-by-step explanation:

We can find the rate of change, or slope using this formula:

y2 - y1 / x2 - x1 = m

M = Slope

y2 and y1 = the y coordinates of the 2 chosen points on the graph

x2 and x1 = the x coordinates of the 2 chosen points on the graph

So, I chose the points:

(0,-3) and (-2,4)

y1: -3

y2: 4

x2: -2

x1: 0

(4) - (-3) / (-2) - (0) =

4 + 3 / -2 - 0 

7/-2

-7/2 <--- Slope (or rate of change)

What is the range of the function y=-x^2 + 1
dedylja [7]

Answer:

The range is:

(−∞,1]

Step-by-step explanation:

Someone plz help me. I'm really confused.
tatuchka [14]

Answer:

2) 1 dozen apple ( 12 apples ) = $4.92

1 apple = $4.92/12

= $0.41

3) distance = speed × time

= 9/10 × 10

= 9 miles

4) 61 minutes = 183 pages

1 minute = 3 pages

5) 8 days = 7 boats

1 day = 7/8 boats

6) speed = distance/ time

= 288/4

= 72 miles/hour

7) 5 cup of flour = 4 cups of sugar

1 cup of flour = 4/5 cup of sugar

Define mass and volume flow rates. How are they related to each other?
Anettt [7]

Answer:

The mass of a substance that passes per unit of time is called the mass flow rate, the unit of mass flow rate is kilogram per second in SI units.

\rho=\frac{\dot{M}}{\dot{V}}

Step-by-step explanation:

Consider the provided information.

We need to Define mass and volume flow rates and how they are related.

The mass of a substance that passes per unit of time is called the mass flow rate, the unit of mass flow rate is kilogram per second in SI units.

The volume of fluid which passes per unit time is called volume flow rate.

The relation between them is:

The Mass flow rate = Density × Volume flow rate

Or

\rho=\frac{\dot{M}}{\dot{V}}

Where ρ is the density.
