Evaluate the expression for x = 1.7. Enter your answer in the box.
x2 + 3x

Answers

Answer 1

Answer:

7.99

Step-by-step explanation:

You have the following expression:

x^2 + 3x

In order to determine the value of the previous expression for x = 1.7, replace this value into the previous expression and simplify:

(1.7)^2 + 3(1.7) = 2.89 + 5.1 = 7.99

Hence, the result is 7.99

A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function f(x)=-5x2+6x+100 (graphed below) represents this situation where x is time and y is the distance off of the ground.

e. What would the new function be? What kind of transformation is this?
f. Would you still use the same domain and range? Why or why not?

Answers

Answer:

a) The domain of the function is    . , , b)The range of the function is . , , c) The ball is 73 meters off of the ground at x = 3 seconds.Step-by-step explanation:The complete statement is: A ball is thrown upward off of a 100 meter cliff with an initial velocity of 6 m/s. The function represents this situation where x is time and y is the distance off of the ground. a) What domain does the function make sense? b) What range does the function make sense ? c) How far off the ground is the ball at time x = 3 seconds?a) Let  and  be the time, measured in seconds, and the distance of the ground, measured in meters, respectively. Time is a positive variable, so domain corresponds to the interval when  and . That is: Therefore, the domain of the function is    . , b) The distance off of the ground is also a positive variable, where ball is thrown upward at a height of 100 meters and hits the ground at a height of 0 meters. Hence, the range of the function is . , c) The distance of the ball off of the ground at x = 3 seconds is found by evaluating the function:The ball is 73 meters off of the ground at x = 3 seconds.

Answers

Answer: 120

120

Step-by-step explanation:

I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)

P/w = part/whole = ?/400

%/100= percent/100 = 30%/100

These numbers are equivalent

If you don’t understand the top then here is how to do the work-

400x30=12000

12000/100=120

Therefore it’s 120

Jordan works at a bakery. The owner tells Jordan she wants to take 20% off a $75.00 cake. If the cake still doesn't sell, the owner will again reduce the price by 10%. Jordan tells the owner to reduce the original price by 30% because the sale price would be the same.

Is Jordan correct?

Yes, the owner's method and Jordan's method both equal a 30% discount off the original price.

Yes, the sale price for both the owner's method and Jordan's method is $52.50.

What is the multiplicative rate of change of the function?

1/3
2/3

9

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

When you encounter a word you don't know, look for context clues that might help you define the word.Scientists can't directly observe black holes with telescopes that detect X-rays, light, or other forms of electromagnetic radiation. We can, however, infer the presence of black holes and study them by detecting their effect on other matter nearby. If a black hole passes through a cloud of interstellar matter, for example, it will draw matter inward in a process known as accretion. A similar process can occur if a normal star passes close to a black hole. In this case, the black hole can tear the star apart as it pulls it toward itself. As the attracted matter accelerates and heats up, it emits X-rays that radiate into space. Recent discoveries offer some tantalizing evidence that black holes have a dramatic influence on the neighborhoods around them--emitting powerful gamma ray bursts, devouring nearby stars, and spurring the growth of new stars in some areas while stalling it in others.Considering all of the context clues around the word telescopes, what can you assume that telescopes are able to do?A)see black holes clearlyB)detect X-rays, light, and electromagnetic radiationC)predict when a new black hole has formedD)see gamma ray bursts How does the king contribute to the central conflict in "Perseus and the Quest for Medusa's Head"?Perseus holds up Medusa's head and turns the king to stone.The king requests that Perseus bring him Medusa's head.The king says that he will never let Perseus marry his daughter.The king laughs at Perseus and makes him feel ashamed.
