50 POINTS!!!! Amy is attending a trekking camp. She walks from her tent to a hilltop in 3 hours. She has a picnic with her friends on the hilltop for 5 hours. Amy walks back to her tent in 2 hours. Which graph best represents the distance, y, in miles, traveled by Amy for a certain amount of time, x, in hours?
Answers
Answer: B
Step-by-step explanation: We know that Amy took three hours to get to the hilltop, so A and D are out because they are saying she reached the hilltop in 2 hours, instead of 3. Then we have C and B left. The difference between them is that C is saying that they had a picnic for 4 hours instead of 5.
hope this helps!
please give brainliest!
Answer:
B
Step-by-step explanation:
The given graphs are distance-time graphs, where:
Time is on the x-axis.Distance is on the y-axis.As Amy walks from her tent to a hilltop in 3 hours, the first part of the graph should be a straight line with a positive gradient, where the x-values of its endpoints are:
x = 0 and x = 3.Therefore, we can immediately discount answer options A and D as they suggest that this part of Amy's journey takes only 2 hours.
Amy stops and has a picnic at the top of the hilltop for 5 hours. Therefore, her distance from the tent during this time does not change as she is not moving. This will be represented on the graph by a horizontal line that has endpoints at:
x = 3 and x = 8.Therefore, the graph that displays the given parameters is graph B.

A client asked Leah to design a rectangular garden with a length that is two feet less than three times the width: The client also asked that the garden have an area of 33 square feet: What is the length?
Answers
The length of the rectangular garden is 9 feet.
Let x = length of the rectangular garden in feet
y = width of the rectangular garden in feet
If a client asked Leah to design a rectangular garden with a length that is two feet less than three times the width, then
x = 3y - 2 (equation 1)
If the rectangular garden is to have an area of 33 square feet, then the product of the length and width should be equal to 33 square feet.
A = l x w
33 = xy
Substitute the expression for x and solve for y.
33 = xy
33 = (3y - 2)y
33 = 3y² - 2y
3y² - 2y - 33 = 0
(3y - 11)(y + 3) = 0
3y - 11 = 0 ; y + 3 = 0
3y = 11 ; y = -3
y = 11/3
Substitute the value of y and solve for x.
x = 3y - 2 (equation 1)
x = 3(11/3) - 2
x = 9
length of the rectangular garden = 9 feet

How do I solve explain steps
Answers
Answer:
There's no real solutions to this expression.
Step-by-step explanation:
5x - (3 - 2x) = - (-x - 7) + 6x
First we need to get rid of the parenthesis and to do that we multiply inside the parenthesis with -15x - 3 + 2x = x + 6 + 6x (remember, negative × negative = positive)
Now add/subtract like terms:5x + 2x - 3 = 7x - 3
x + 6x + 7 = 7x + 7
Rewrite the equation:7x - 3 = 7x + 7, 7x will eliminate each other so we will be left with,
-3 = 7 which cannot be true so we say there's no real solutions to this expression.

the initial size of a bacteria culture is 1000. after one hour the bacteria count is 8000. after how many hours will the bacteria population reach 15000? assume the population grows exponentially. (you may leave e, ln, or log in your answer.)
Answers
The time required by the bacteria to reach 15000 is :
log(2)/log(1.5) = t
Given:
P(t) = P0·bt
P(t) = bacteria population at time t
P0 = starting bacteria population = 10,000
b = growth rate
t = days
we are asked to find out after how many hours will the bacteria population reach 15000 = ?
P(t) = P0·bt
At t = 1 day, P(t=1) = 15,000:
15,000 = 10,000·b1
15,000/10,000 = b
1.5 = b
P(t) = 10,000·1.5t
Population doubles when P(t) = 20,000:
20,000 = 10,000·1.5t
2 = 1.5t
log(2) = log(1.5t)
log(2) = t·log(1.5) [Log property: log(ab) = b·log(a)]

Distribute the "3" on the left side of the equation, then isolate the variable on one side:
3(x - 8) + 4x = 8x + 4
3x - 24 + 4x = 8x + 4

What is simple interest ?
The principal of a loan or the initial deposit into a savings account serves as the foundation for simple interest. Simple interest does not compound, therefore the creditor only has to pay interest on the capital sum and the borrower never has to pay interest on the interest that has already accrued.
Simple Interest formula
I = (P*T*R)/100
The given values are
I = 50000
P = 50000
R = 5%

T = (I*100)/(P*R)

The binary search tree is better than the sorted link with respect to efficiency and intricacy.
Comparing a sorted linked list to a binary search tree for up to 1000 integer members, the intricacy of the algorithm in the sorted linked list grows over time. It differs depending on where the seeking element is located in sorted links. It requires little time if the searching element is present at the beginning of the linked list. However, in a linked list, the worst-case scenario occurs if the seeking element is present at 1000. Searching for the element in that position takes a long time.
The 1000 elements in a binary search split into two main wings. This type of search varies in difficulty depending on tree height. In the worst situation, if there are about equal numbers of elements on the left and right sides of the wing, searching for an element takes about half as long as searching for it in sorted links. Binary is more effective than Sorted as it uses a binary search algorithm instead of the linear search technique used by linked lists.
