The table below represents the displacement of a fish from its reef as a function of time:

Mathematics
1 answer:
diamong [38]3 years ago
3 0

Answer:

A. Here the y-intercept is (0,4) and means at time 0 hours the fish is displaced 4 feet.

B. For every hour, the fish is displaced 60 more feet.

C. The domain is [0, 12].

Step-by-step explanation:

Part A:

The y-intercept is where the function intersects the y-axis. It is the point (0,b) and is always the starting value in real world situations since time begins at x=0. Here the y-intercept is (0,4) and means at time 0 hours the fish is displaced 4 feet.

Part B:

The average rate of change is the slope of the function found using the formula m = \frac{y_2-y_1}{x_2-x_1}. Use the points (0,4) and (1,64).

m = \frac{y_2-y_1}{x_2-x_1} =\frac{64-4}{1-0} =\frac{60}{1} =60

For every hour, the fish is displaced 60 more feet.

Part C:

The domain is the set or group of x values in the function. Time starts at 0 and goes until the fish traveled 724 feet. What time is this at?

The function has the equation y = 60 +4. Find the time by substituting y=724.

724=60x+4

720 = 60x

12=x.

The domain is [0, 12].

A candy bar box is in the shape of a triangular prism the volume of the box is 2400 cubic centimeters part A: what is the height
Whitepunk [10]
The volume of a triangular prism is the "area of a triangle" times the "thickness."
The area of a triangle is (base times height) over 2.
V = ((b*h)/2)*T
Given V = 2400 cu. cm, b = 16 cm, T = 20 cm, and h is unknown,
h = (2V)/(bL) = (2*2400)/(16*20) = 15 cm

Note that the given 17 cm in the picture is useless.

Paladinen [302]

Answer:

  1. FALSE
  2. TRUE
  3. TRUE

Step-by-step explanation:

<u>1.</u>

  • Non-standard units can be used to measure volume
  • Examples : m³, in³, cm³, mm³, L

<u>2.</u>

  • The volume of a rectangular prism can be found by multiplying the length, width, and height
  • <u>V = lwh</u>

<u />

<u>3.</u>

  • If there are smaller units, then naturally more of the units will be used
  • If there are larger units, then less of the units will be used

What would happen if a proton were added to the nucleus of the atom? (Check all
Hunter-Best [27]

Answer:

A. It would become a different atom.

C. Its charge would increase by 1

Step-by-step explanation:

Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is! For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
