The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes:
Part A: Describe how you can use similar triangles to explain why the slope of the graph between points A and B is the same as the slope of the graph between points A and C.
Part B: What are the initial value and slope of the graph and what do they represent?
Answers
Step-by-step explanation:The slope of AB and BC are the same.
The initial value is 60 m and the slope is 40 m/min.
Step-by-step explanation:
The graph shows the depth, y, in meters, of a shark from the surface of an ocean for a certain amount of time, x, in minutes.
See the graph attached.
Part A : If we consider two right triangles one Δ ABD and Δ BCE, where D(2,100) and E(1,60) points.
Now, those two triangles are similar and hence the slope of line segment AB will be .
Again, the slope of the line segment BC will be
Hence, and the slope of AB and BC are the same. (Answer)
Part B : From the graph, it is clear that the initial value of the graph is 60 m and it represents that initial position of the shark i.e. at t = 0 min, the shark was at a depth of 60 m from the water surface.
The slope of the graph is 40 means the rate of change of distance from the Ocean surface of the shark with respect to time in minutes will be 40 m per min. (Answer)

Step-by-step explanation:
Step-by-step explanation:
First, you need to know some terms related to probability. When working with probability, a random action or series of actions is called a trial. An outcome is the result of a trial, and an event is a particular collection of outcomes. Events are usually described using a common characteristic of the outcomes.
Let's apply this language to see how the terms work in practice. Some games require rolling a die with six sides, numbered from 1 to 6. (Dice is the plural of the die.) The chart below illustrates the use of trial, outcome, and event for such a game:
Trial
Outcomes
Examples of Events
Rolling a die
There are 6 possible outcomes:
{1, 2, 3, 4, 5, 6}
Rolling an even number: {2, 4, 6}
Rolling a 3: {3}
Rolling a 1 or a 3: {1, 3}
Rolling a 1 and a 3: { } (Only one number can be rolled, so this outcome is impossible. The event has no outcomes in it.)
Notice that a collection of outcomes is put in braces and separated by commas.
A simple event is an event with only one outcome. Rolling a 1 would be a simple event because there is only one outcome that works—1! Rolling more than a 5 would also be a simple event because the event includes only 6 as a valid outcome. A compound event is an event with more than one outcome. For example, in rolling one six-sided die, rolling an even number could occur with one of three outcomes: 2, 4, and 6.
When you roll a six-sided die many times, you should not expect any outcome to happen more often than another (assuming that it is a fair die). The outcomes in a situation like this are said to be equally likely. It’s very important to recognize when outcomes are equally likely when calculating probability. Since each outcome in the die-rolling trial is equally likely, you would expect to get each outcome of the rolls. That is, you'd expect the rolls to be 1, of the rolls to be 2, of the rolls to be 3, and so on.
A spinner is divided into four equal parts, each colored with a different color as shown below. When this spinner is spun, the arrow points to one of the colors. Are the outcomes equally likely?
A) Yes, they are equally likely.
B) No, they are not equally likely.
Answer:
All the outcomes are equally likely. Each color provides a different outcome, and each color takes up the circle. You would expect the arrow to point to each color of the time.

Answers
Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
Answer:
Below
Step-by-step explanation:
Brianna's teacher asks her which of these three expressions are equivalent to each other
Expression A: 9x−3x−4 Expression B: 12x−4 Expression C: 5x+x−4
Brianna says that all three expressions are equivalent because the value of each one is −4 when x=0.
Brianna's thinking is incorrect. Identify the error in Brianna's thinking. Determine which of the three expressions are equivalent. Explain or show your process in determining which expressions are equivalent. Enter your answers and your explanation or process in the space provided.
So let's just simplify A and C. B is already simplified.
9x-3x-4
6x-4
5x+x-4
6x-4
So yes, Brianna is incorrect. She added 3x and 9x, instead of subtracting 3x from 9x. A and C are equivalent, but B is all alone.

Answer:
18 1/12 ft = base length
Step-by-step explanation:
The area of a triangle of base b and height h is A = (1/2)(b)(h).
Since we want the measure of the base we solve this formula for b:
2A = (b)(h)
2A
and then divide both sides to obtain a formula for b: b = -----------
h
Substituting 217 ft^2 for A and 24 ft for h, we get:
b = 2*217 ft^2 / 24 ft = 18.0833.... ft
If the answer must contain a fraction, take the 18 and hold it and convert the remaining 0.08333... to a fraction. One way of doing this is to use a calculator. On my old TI calculator, I would type in 0.0833333333..
and then press the MATH key and then select Option 1: Decimal to fraction.
Doing this yields 1/12. You can check this result by dividing: 1/12 = 0.08333...
Then the final answer, converted from 18.08333... ft, is
18 1/12 ft = base length

The degree of this polynomial is 3.
Step-by-step explanation:
Hey!
==================================================================
When a polynomial has more than one variable, we need to look at each term to find out what the degree is. Terms are separated by + or - signs.
Find the degree by adding the exponents of each variable in it,
The largest such degree is the degree of the polynomial.
Let's start out by finding the degrees for each terms:
3x³ = The degree, or exponent, of x is 3.
5x² = The degree, or exponent, of x is 2.
1 = Constant Terms do not have a degree.
So, since the largest degree of a term is the degree of the polynomial., The degree of this polynomial is 3, since that is the highest!

A block of iron has dimensions of 1 cm x 2 cm x 5 cm and has a
mass of 799
What is its density? (V=lxwxh)
Answers
Answer:
79.9 units
Step-by-step explanation:
Hi there,
Before solving this problem, it is important to know the formula:
D = [tex]\frac{m}{v}[/tex].
D = density
m = mass
v = volume
Since we are given the mass and volume, we can simply enter these values into the formula to find the density of the block.
D = [tex]\frac{799}{10}[/tex]
D = 79.9
Therefore, the density of the block of iron is 79.9 units. I wrote units since you did not specify the unit for the mass. Hope this answer and explanation helps.
Cheers.
