Answer:

Step-by-step explanation:
Which graph represents the function f(x)=√x+4-2?
Answer:
the top right graph
Step-by-step explanation:
I assume you mean the function is
f(x) = sqrt(x + 4) - 2
because for your function as you wrote it
f(x) = sqrt(x) + 4 - 2 = sqrt(x) + 2
none of the graphs apply.
to find the correct one we look at some specific points.
like x = 0, and when the square root will be 0 (x = -4).
normally we can see the right graph latest here already, but if not, then we have to pick a few more points.
so,
for x = 0 we get
sqrt(0 + 4) - 2 = 2 - 2 = 0
that means
f(0) = 0
now, when we look at the graphs, we see we are already finished. there is only one graph that goes through (0, 0).
the top right graph.
The graph shows the velocity f(t) of a runner during a certain time interval:
Graph of line segment going through ordered pairs 0, 4 and 4, 8. Graph of another line segment going through ordered pairs 4, 8 and 8, 0. Label on the x axis is time in seconds, and label on the y axis is velocity in meters per second.
Which of the following describes the intercepts on the graph?
The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds.
The initial velocity of the runner was 8 m/s, and the runner stopped after 4 seconds.
The initial acceleration of the runner was 4 m/s2, and the runner stopped after 8 seconds.
The initial acceleration of the runner was 8 m/s2, and the runner stopped after 4 second
The description of the intercepts of the Graph segments passing through the points (0, 4), (4, 8), (4, 8) and (8, 0) is given by the option;
The initial velocity of the runner was 4 m/s and the runner stopped after 8 secondsWhat is a velocity time graph?A velocity time graph is a graph that shows how the velocity of an object changes with time
The given information on the graph are;
The coordinates of the points on the Graph of the first line segment = (0, 4) and (4, 8)
On Graph of the second line segment, the coordinates of the points = (4, 8), (8, 0)
The label of the axis of the graph are;
X–axis label = Time in seconds (s)
Y–axis label = Velocity in m/s
Required; The option that gives the description of the intercepts of the graph
Solution; The x and y–intercept are given as follows;
At the x–intercept the y–value is 0, which gives the x–intercept of the graph as the point (8, 0)
Given that the y–value which is the value of the velocity, is 0, it means that the runner stops at the point (8, 0), or after 8 seconds
At the y–intercept, the x–value is 0. The y–intercept is therefore the point (0, 4)
The 0 in the y–intercept means that the time is 0 seconds, which is the starting or initial time, while the 4 means that the velocity is 4 m/s.
Therefore, the y–intercept (0, 4) can be described as the initial velocity of the runner is 4 m/s
The description of the intercepts on the graph are therefore;
The initial velocity of the runner was 4 m/s and the runner stopped after 8 seconds.Learn more about velocity time graphs here:

#SPJ1
Answer:
The initial velocity of the runner was 4 m/s, and the runner stopped after 4 seconds and then again after 8 seconds. Option A is the correct answer
Step-by-step explanation:
The intercepts on the graph can be described as follows:- The y-intercept is the point at which the line intersects the y-axis, and it represents the initial velocity of the runner. In this case, the y-intercept is at (0, 4), which means that the initial velocity of the runner was 4 m/s.- The x-intercept is the point at which the line intersects the x-axis, and it represents the time at which the runner stopped. In this case, there are two x-intercepts: one at (4, 8) and another at (8, 0).
This means that the runner stopped twice, once after 4 seconds and again after 8 seconds.
Therefore, the correct description of the intercepts on the graph is: The initial velocity of the runner was 4 m/s, and the runner stopped after 4 seconds and then again after 8 seconds. Option A is the correct answer.

$10,000 for 5 years at 4% interest
Simple interest earned on the principal amount $10,000 for 5 years at 4% interest per year will be $12,000.
As given in the question,
Simple Interest:
The simple interest is an amount that is paid for loan or borrowed money over a certain period at a fixed percentage of borrowed money.
Principal amount:
Principal amount is the money that is taken as loan or borrowed.
Formula of Simple Interest:
Simple interest = Principal amount × Rate × Time
Since,
Principal amount = $10,000
Rate = 4% per year
Time = 5 years
Then,
Simple interest = 10,000 × 4 × 5
Simple interest = $ 12000
Total value after 5 years = $ 12000
Principal amount = $ 10000
Interest Earned = (Total value) - (Principal amount)
Interest Earned = $ 12000 - $ 10000
Interest Earned = $ 2000
Therefore, simple interest earned on the principal amount $10,000 for 5 years at 4% interest per year will be $12,000.
The complete question is:

In Euclidean geometry, any three points that are not collinear produce a singular triangle and a singular plane (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and there is only one plane that contains that triangle. All the triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except when otherwise specified, this article discusses the triangles in Euclidean geometry, namely the Euclidean plane.

#2 The number of bacteria in a refrigerated food is given by N(T)=20T2-20T+120 for -2T14 Tand where T is the temperature of the food in Celsius.
(a)Explain the meaning of -2T14 in this context
(b)Determine the temperature the number of bacteria will be minimal?
(c)Find number of bacteria in a above
(d) Sketch a graph
From the given quadratic function, it is found that:
a) The interval -2 ≤ T ≤ 14 gives the range of the temperature of the food in Celsius.
b) The number of bacteria will be minimal for a temperature of 0.5 ºC.
c) The minimum number of bacteria is of 115.
d) The graph that models the situation is sketched at the end of the answer.
What does the quadratic function models in this problem?The quadratic function is given as follows:
N(T) = 20T² - 20T + 120, -2 ≤ T ≤ 14.
In which:
T is the temperature in Celsius of the food.N(T) is the number of bacteria in the food.The function has a domain of -2 ≤ T ≤ 14, meaning that these are the possible temperatures of the food.
For a concave up quadratic function, the minimum value happens when the input is of:
Tm = -b/2a.
For this problem, the coefficients of the quadratic function are as follows:
b = -20, a = 20.
Hence the temperature in which the number of bacteria will be minimal is of:
Tm = 20/40 = 0.5 ºC.
The number of bacteria with this temperature is given by the numeric value of the function when T = 0.5, that is, each instance of T in the function is replaced by 0.5, hence:
N(0.5) = 20(0.5)² - 20(0.5) + 120 = 115 bacteria.

Answer: Why it makes sense: When we compare or order decimals we need to compare place values just like we do with whole numbers. When the edges are “jagged” it makes it harder to compare each decimal place. Adding a zero in an empty place value makes it easier to compare the numbers.

1. how do we change a similar fraction?
2. how do we add the similar fraction?
Answer:
You add similar fraction by adding the numerators together but since the denominators are the same u keep them as they are
1. Similar fractions are those which have the same denominator. To change dissimilar fraction to similar fractions, you express them as a equivalent with a common denominator. For example 2/12, 3/12
2. To add similar fraction one should ensure that both the numerator are same and then add the numerator and put that on the denominator. If there is need to simply the fraction then you should first simplify the fraction.
For example:- 1/4+4/4= 5/4
Here as we see that bot number denominator are same so it's addition is done easily
What is the equation for the line that passes through the coordinates (-4,-12)and(16,3)
The equation of the line that passes through these coordinates is 3x-4y= 36
How to calculate slope?
If you have the coordinates of two points on a line, you can use the slope formula to determine that line's slope. m=(y2-y1)/(x2-x1), or the ratio of the change in the y values to the change in the x values, is the slope formula.
To find the equation of the line we first have to find the slope which is represented by m.
The slope or m is given by : y₂ - y₁ / x₂ - x₁
thus, m= 3-(-12)/ 16-(-4)
m= 3+12/ 16+4 = 15/20
m= 3/4
The equation of a slope is y-y₁=m (x-x₁)
y- (-12) = 3/4 (x- (-4))
y+12 = 3/4 (x+4)
On solving it further we get:
