Answer 2

2 Answers: Choice A and choice C

======================================================

Explanation:

AB = BC refers to the fact that expressions 2x+7 and 4x-3 are equivalent. They represent numbers when we replace x with some number. So after doing that replacement, we have something in the form number = number.

So this is why choice A is one of the answers.

[tex]\overline{AB} \cong \overline{BC}[/tex] says "segment AB is congruent to segment BC". The horizontal lines over the lettering indicates we have a segment. The equal sign with a squiggle over top is the congruence symbol. In geometry, we say two items are congruent if they are the same. You can think of making a clone of the object and then sliding it over. In this case, we've cloned segment AB to form segment BC.

This is why choice C is the other answer.

--------------

Choices B and D are close, but not quite correct. Choice B is missing the segment markers. Choice D is missing the congruence symbol. Congruence and equality are very similar ideas, so often they get mixed up.

Which statement correctly compares the function shown on this graph with
the function y = 2x - 5?

A. The function shown on the graph has a smaller rate of change and lower starting point.

B. The function shown on the graph has a smaller rate of change, but a higher starting point.

C. The function shown on the graph has a greater rate of change and a higher starting point.

D. The function shown on the graph has a greater rate of change, but a lower starting point.

Answers

It’s c because I just got finishes taking the test

The correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

What is the rate of change of function?

The rate of change of function is the change in the value of the function with respect to x value.

rate of change of function f(x)= df(x)/dx= f'(x)

Here the function given in the question is y=2x-5

rate of change of function= f'(x)= df(x)/dx= dy/dx= d(2x-5)/dx= 2

the starting point of the function f is y-intercept of the function.

the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

y= 2x-5

⇒y= 2*0-5

⇒y= -5

The starting point of function is -5.

Given the graph has slope = |y-intercept| / |x intercept|

= 4/1 =4

rate of change of graph = slope of graph= 4

similarly, the y-intercept of the function is the point where the function touches the y-axis which can be calculated by putting x value is equals to 0.

The y-intercept of the graph= the starting point of the graph= -5

Therefore the function in the graph has a higher rate of change as well as a higher starting point.

From the above, it is clear that the correct option is Option C: The function shown on the graph has a greater rate of change and a higher starting point.

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000
signatures before she can schedule a meeting with the mayor. She already has 380 signatures. If each petition page
holds 80 signatures, which inequality best shows how many more pages (p) Devin needs?

Answers

Answer:

P = t - f

Step-by-step explanation:

First we need to find how many pages in total she needs so 1,000/80 - 12.5 so 13 pages. Then 380/80 4.75 of a page filled so subtract that from 12.5 to get 8 pages left to fill.

let p = pages left to fill

let T = total pages needed

let F = pages already filled

Answer:

$5.40 for 12 letters

Step-by-step explanation:

you need to find the cost for 1 unit then multiply that by 12, so you take the cost (4.50) and divide it by letters (10) so you get 0.45. So that is the cost of q letter, then you that that unit rate and multi[ly it by the number that you need to figure out (12) so .45x12=5.40

equation
h(t) =
2) How many minutes after takeoff does the drone land on the ground?
minutes

Answers

Answer:

h(t) = -3(t-8)(t+4). and 8 minutes

Step-by-step explanation:

The function can be written as: h(t) = - 3(t² - 4t - 32). As per quadratic equation, after take off, the drone will land on the ground after 8 minutes.

What is a quadratic equation?

A quadratic equation is an equation that contains a variable with highest degree of 2.

Given, the height of the drone t minutes after take off is modeled by

h(t) = - 3t² + 12t + 96 = - 3(t² - 4t - 32)

Therefore, the function can be written as: h(t) = - 3(t² - 4t - 32)

Therefore, we can write the equation as:

t² - 4t - 32 = 0

⇒ t²- 8t + 4t - 32 = 0

⇒ t(t - 8) + 4(t - 8) = 0

⇒ (t + 4)(t - 8) = 0

Hence, (t + 4) = 0 and (t - 8) = 0

Therefore, t = -4, 8.

As 't' can't be negative, therefore, t = 8.

Therefore, after take off, the drone will land on the ground after 8 minutes.

Which of the following quantities are inversely proportional? WILL GIVE BRAINIEST

a

The number of hours worked and the amount of money earned, assuming the worker is paid by the hour

Answers

Answer:

option 1

option 3

option 4

Step-by-step explanation:

Inversely proportional means "one quality increases, the other decreases " or "one quantity decreases ,other increases. " Inverse relantionship, that's it.

option 1:

Since the volume is given as 56 and we know the volume is area of base * height, to keep the volume at constant [56], if height increases, area of base would need to decrease, and vice versa. So Inversely proportional.

option 2:

The time spend in plowing a field with a tractor with increase when we area using more fuel.So more fuel used means more time spent. So these are directly proportional, Not inverse.

option 3:

Since the price is a constant, the amount of length we buy more,the price per one yard HAS to decrease, and vice versa. So ,this is Inverse relantionship.

option 4:

If the number of identical tractors. increase, it will take less time to plow the set 358 acre farm. And vice versa. So this is Inversely proportional as well.

Step-by-step explanation:

Using inverse function concepts, the correct option is:

B. Domain: x < -2 Range: y> 3

--------------------------

The domain of a function is the set that contains all possible input values.The range of a function is the set that contains all possible output values.In the inverse function, input and output are exchanged, thus, domain and range are also exchanged.

For the original function, the domain is x > 3 and the range is y < -2.Thus, for the inverse function, the domain is x < -2 and the range is y > 3, which means that option B is correct.
