Given:

The right triangular prism.

Height of prism = 28 in.

Hypotenuse of base = 25 in.

leg of base = 24 in.

To find:

The lateral surface area of the prism.

Solution:

Pythagoras theorem:

Hypotenuse^2=Perpendicular^2+Base^2

Using Pythagoras theorem in the base triangle, we get

25^2=24^2+Base^2

625-576=Base^2

\sqrt{49}=Base

7=Base

The perimeter of the triangular base is:

P=7+25+24

P=56

Lateral area of a triangular prism is:

A=Ph

Where, P is the perimeter of the triangular base and h is the height of the prism.

Putting P=56,h=28 in the above formula, we get

A=56(28)

A=1568

Therefore, the lateral area of the prism is 1568 in².

Do you think this graph looks more like a quadratic or exponential function? Why do you think so?
pantera1 [17]

Answer:

Exponential Function

Step-by-step explanation:

The y-axis represents the number of Bacteria and x-axis represents the number of hours. If you observe closely you will see that the number of bacteria are doubling after each hour. For example, at time = 4 hours the number of Bacteria were about 50, at time = 5 hours the number of Bacteria were about 100 and at time = 6 hours the number of Bacteria increased to about 200.

This type of behavior is a property of exponential functions where we see a multiplicative rate of change in the values i.e. each value is a multiple of previous value. A rough model for this function would be:

f(x)=f(0)(2)^{x}

Where, f(0) represents the number of bacteria at time = 0 hours i.e. number of Bacteria initially present and "x" represents the number of hours.

An engineer is building a bridge that should be able to hold a maximum weight of 1 ton. He builds a model of the bridge that is
MrRissso [65]

Answer:

First blank- 32000 ounces

Second blank- 2000 pounds

Yes the bridge can hold 1 ton.

Step-by-step explanation:

The ratio of the scale of the model to the real bridge = 1:4

The test model shows the model can take 8000 ounces

The real bridge will therefore take 8000 x 4 = 32000 ounces

16 ounces = 1 pound

32000 ounces =  x pounds

==>  = 32000/16 = 2000 pounds

2000 pounds = 1 ton

therefore the bridge holds 1 ton
