Step-by-step explanation:

It says that they already started off with $400 and raise $80 a day, and d stands for the number of days.

It's basically $80 a day being added on to the $400 that was already collected.

So it's 80d+400=7,600

1500 soldiers in a fort have provision for 48 days.After 13 days few soldiers join them and the food lasts 25 days how many soldiers join

Answers

Answer: This is a problem of inverse variation, where the number of days that the food lasts is inversely proportional to the number of soldiers in the fort. We can use the formula:

d = k / s

where d is the number of days, s is the number of soldiers, and k is a constant of proportionality. We can find the value of k by using the initial information:

48 = k / 1500 k = 48 * 1500 k = 72000

Now we can use the information after 13 days to find the new number of soldiers. Let x be the number of soldiers who joined the fort. Then we have:

25 = 72000 / (1500 + x) 25 * (1500 + x) = 72000 37500 + 25x = 72000 25x = 34500 x = 1380

Answer: The number of soldiers who joined the fort after 13 days is 1380.

A toy rocket was launched from the ground. The function f(x) = -16x2 + 160x shows the height of the rocket f(x), in feet, from the ground at time x seconds.What is the axis of symmetry of the graph of f(x), and what does it represent?

These are the choices:
x = 10; it takes 10 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 10; it takes 10 seconds to reach the maximum height and 20 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 10 seconds to fall back to the ground
x = 5; it takes 5 seconds to reach the maximum height and 5 seconds to fall back to the ground

g(p)=(p-2 )and g(x)=(p^3+4p^2-2) evaluate g(p)*h(p) by modeling or by using the distributive property.

Answers

Given that g(p)=p-2 and

h(p)=p^3+4p^2-2

Now we have to evaluate g(p)*h(p) by modeling or by using the distributive property.

We know that g(p)*h(p) means just multiply expressions of g(p) with h(p)

which can be shown as following:

g(p)*h(p)=(p^3+4p^2-2)(p-2)


Apply distributive property

g(p)*h(p)=p(p^3+4p^2-2)-2(p^3+4p^2-2)


g(p)*h(p)=p^4+4p^3-2p-2p^3-8p^2+4


g(p)*h(p)=p^4+2p^3-2p-8p^2+4


g(p)*h(p)=p^4+2p^3-8p^2-2p+4

Hence final answer is g(p)*h(p)=p^4+2p^3-8p^2-2p+4

Sales at a fast-food restaurant average $6,000 per day. The restaurant decided to introduce an advertising campaign to increase daily sales. To determine the effectiveness of the advertising campaign, a sample of 49 days of sales were taken. They found that the average daily sales were $6,300 per day. From past history, the restaurant knew that its population standard deviation is about $1,000. If the level of significance is 0.01, have sales increased as a result of the advertising campaign? Multiple Choice A. Reject the null hypothesis and conclude that the mean is equal to $6,000 per day. B. Fail to reject the null hypothesis. C. Reject the null hypothesis and conclude the mean is lower than $6,000 per day. D. Reject the null hypothesis and conclude the mean is higher than $6,000 per day.
