The height of a water balloon that is launched into the air is given by h(t) = -5t2 + 40t + 2. From what height was the balloon released? a) 2 meters (b) 5 meters O c) 40 meters d) 20 meters​

Answers

Answer 1

Answer:

a.

2 meters

Explanation:

The equation:  h(t) = -5t2 + 40t + 2. is the position or height equation. It is the equation of a parabola. Since the leading coefficient -16 is negative, we have a parabola that has a maximum (a vertex is the highest point).

The easiest way to find the maximum height is to find the vertex since the y-value of the vertex is the maximum height. When the equation is in the form Ax2 + Bx + C = 0, the vertex is (-B/(2A), h(-B/(2A))).

-B/(2A) = -32/(2*-16) = -32/-32 = 1

h(1) = -16(1)2 + 32(1) + 48 = 2 feet

Read the excerpt from The Wind in the Willows by Kenneth Grahame. The Mole had been working very hard all the morning, spring-cleaning his little home. First with brooms, then with dusters; then on ladders and steps and chairs, with a brush and a pail of whitewash; till he had dust in his throat and eyes, and splashes of whitewash all over his black fur, and an aching back and weary arms. How does the author’s word choice help express the tone of the excerpt? The negative connotations of the words “dust,” “aching,” and “weary” give the excerpt a tone of relaxation. The negative connotations of the words “dust,” “aching,” and “weary” give the excerpt a tone of tiredness. The positive connotations of the words “home,” “morning,” and “splashes” give the excerpt a tone of relaxation. The positive connotations of the words “home,” “morning,” and “splashes” give the excerpt a tone of tiredness.

Answers

Answer: B, the negative connotations of the words “dust,” “aching,” and “weary” give the excerpt a tone of tiredness.

Explanation:

In the excerpt, we learn that the mole has been working hard, and that he worked all morning. Spring-cleaning usually implies a deep cleaning, like replacing the carpet or cleaning your oven. However, when someone typically does some spring-cleaning, they end up tired. We can prove this by using the words “aching” and “weary,” as they describe being tired.

What would you have done to survive in the Donner Party?Only answer if you're very good at History.Please don't put a link to a website.​

Answers

Answer:

Explanation:

I would have started by trying to bring a Native American guide along. It seems the Donner party wasn't very fluent in Native American customs, and before venturing into the west without an experienced guide. Sometimes having the right people on your team makes an effort easier.

Their fate was pretty much sealed by Jim Bridger, who hid letters from Edwin Bryant that advised against traveling on Hasting's Pass with wagons. At some point, before winter, I would have made a makeshift shelter for the women and children, and left a few men to guard them. I would have sent the rest of the men forward to explore the rest of the pass or find more help, fresh horses/oxen and more wagons to carry their belongings.

By stopping somewhere before winter, they could have taken advantage of any wild-grown food from the late summer and fall harvest seasons. When food got very scarce, I would have starved myself so my children would eat. I would like to say we would never have resorted to cannibalism. But desperation to keep children alive puts people's ethics at risk of being compromised. And for some, desperation to stay alive themselves makes them put their ethics aside.

I hope this gives you some ideas for your answer.

Which of the following was true for Serfs living in Medieval times? Select all that apply


they provided food in exchange for protection


they were free people


they did not own property


they were the majority of the people at that time


their position in society was inherited by birth


they lived in the manor of their lord but were able to come and go as they pleased

Answers

Answer:

they were free people

they did not own property

their position in society was inherited by birth

Statements- They provided food in exchange for protection.

They did not own property.

Their position in society was inherited by birth, are true for Serfs living in Medieval times.

Serfs played a crucial role in the feudal system in the Middle Ages. They were peasants who worked on land that belonged to a noble or their lord. In exchange for protection and the ability to work on the land one of the main duties of serfs was to provide food and agricultural products to their lord.

The land and its resources belonged to the lord, not the serfs who had no personal property of their own. Birth determined their social standing because serfdom was typically passed down through families. Serfs were confined to their master's manor, bound to the land and required permission to leave. They were constrained to their lord's estate under this system which reduced their personal freedom and mobility.
