Answer:  Below, the bold words indicate prepositional phrases. Only these sentences contain prepositional phrases

The man in the house seemed to be asleep.

The soldiers crept cautiously through the tunnel.

I was informed that the bus would arrive in 45 minutes.

Prepositions are connecting words that act like bridge

A prepositional phrase is a group of words that beings with a preposition and ends with the object of the preposition.

For example, we went fishing with Ben.    Now in this example the connecting word (the bridge) is WITH.

Taking the above example:

We went fishing with Ben

Now, here "with" is the preposition and Ben is the object of the preposition.

Scarlett is trying to find the height of a dam. She stands 90 meters away from the dam and records the angle of elevation to the top of the dam to be 26º. Scarlett's height is 1.65 meters, so the height of the dam is

Make a drawing with a right triangle.

The opposite side, y, is the height of the dam less 1.65 m

The base or adjacent side is 90 m

The angle between the two sides is 90 m.

Then tan (26) = y / 90

y = 90 tan(26) = 90 (0.4877) = 43.90 m

The height of the dam is 43.90m + 1.65m = 45.55 m

Explain why a population of Mouflon in the Indian Ocean descended from only two individual that had not experienced a loss of genetic diversity was so surprising to scientists.

When populations are dramatically reduced in size, the theory of genetic drift suggests that a loss of genetic diversity should be expected. In the case of the Mouflon, however, no such loss in diversity was observed. This result was extremely surprising to scientists because it meant that the theory of genetic drift does not always hold true.

Why don’t DEA agents shut down the Harborside Health Center in Oakland, CA?

On June 7th, Attorney General Eric Holder told Congress he would only enforce federal action against dispensaries that were in direct violation of state law. Meaning – a dispensary had to be actually breaking the law to get raided. In Haag’s own statement she admits this isn’t the case at Harborside – she only believes that due to their size and the high number of patients in their care, a violation is somehow inevitable.

The binomials shown below will be multiplied to produce a quadratic trinomial. (x + p)(x + q) Which part of the trinomial will equal the sum of p and q? A. The constant term B. The coefficient of the x-term C. The degree D. The coefficient of the x2-term

I believe the correct answer from the choices listed above is option B. The part of the trinomial will equal the sum of p and q would be the coefficient term. We do it as follows:

(x + p)(x + q)
x^2 + px + 1x +pq
x^2 + (p+q)x + pq

Hope this answers the question. Have a nice day.

Zoning decisions do not always change over time and can become antiquated. c. Establishing zoning types is an expensive process. d. Zoning regulations prevent new businesses from competing with established businesses

Zoning regulations prevent new businesses from competing with established businesses because legislative regulations categorize the city or county into different zones, which specifies the uses allowable for the property in these areas. However zoning regulations affect the location of each type of business, and it is crucial to home-based businesses.

The main purpose of zoning is to cut off the uses which are thought to be inappropriate. In practice, zoning also used to restrict new development from conflicting with the existing organization to protect the "character" of a society.

The large size of the musk ox _______. a. helps minimize heat loss b. is offset by its long legs c. helps the animal graze less often d. helps maximize heat loss

A.  Helps minimize heat loss

Explanation:

The musk ox is found in cold climatic regions. Its larger body size imparts it a smaller surface area relative to its volume. The lesser surface area, relative to its large volume, exposed to the surroundings helps the organism to lose less heat. Hence, a smaller surface area to volume ratio of musk ox, as contributed by its larger body size, help it to stay warm in cold climates.

You are buying potato chips at the grocery store. You have a manufacturers coupon for a \$1.00 off and the store is offering 20% off if you buy 2 bags. You decide to buy 2 bags of potato chips. How do you compute your final cost? A. Subtract \$1.00 off each bag and then multiply by .20 B. Multiply each bag by .20, subtract \$1.00 off of each bag, and then add them together. C. Add the two bags together, multiply by .80, and then subtract \$1.00. D. Subtract \$1.00 from the first bag, then add them together, and then multiply by .80.

The correct option is:   C.  Add the two bags together, multiply by .80, and then subtract \$1.00.

Step-by-step explanation:

First you need to add the prices of two bags for getting the total sales price.

Now, the store is offering 20% off, that means you need to pay 80% of the total sales price. For finding the amount, we need to multiply the total sales price by 0.80

Then, you have a manufacturers coupon for a \$1.00 off. So, for fining the final price, you need to subtract that \$1.00 from the last result.

Thus, the correct option will be......

C. Add the two bags together, multiply by .80, and then subtract \$1.00.

If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial. true or false

The Factor theorem states that  for any polynomial f(x) if f(c)=0 then x-c is a factor of the polynomial f(x).

If any polynomial f(x) is divided by x-a and remainder is 0 that means f(a)= 0 .In other words we can say x-a is a factor of the polynomial f(x).So the statement :If a polynomial is divided by (x-a) and the remainder equals zero then (x -a) is a factor of the polynomial is True.

A graph thAt has a finite or limited number of data points is

Discrete graph.

Explanation:

A discrete graph is a graph of disconnected points.

Since they are disconnected, this means the graph only has values at the points drawn, not between.

The opposite of a discrete graph is a continuous graph; it is a graph of connected points. Since the points are connected, the graph has values between all of the points. This is similar to what we learned in geometry about a line; a line has an infinite number of points. This is true of the connections between points in a continuous graph.

Since a discrete graph is the opposite of a continuous graph, this means it does not have an infinite number of points; a discrete graph has a finite number of points.
