Which function is positive for the entire interval (-3, -2]?
Graph 2 represents that the function is positive for the entire interval [-3,-2].
What is a function?A function is a relation in which each possible input value leads to exactly one output value. We say “the output is a function of the input.” The input values make up the domain, and the output values make up the range.
We are given four different graphs for different functions. We have to find the graph that is positive for the entire interval [-3,-2].
We make the following observation from the given graphs.
1. In graph 1 the function has a value of 0 at -3 and the value decreases from -3 to -2. Thus the function is negative in the given interval.
2. In graph 2, it can be clearly seen that the function has a positive value, through the entire given interval.
3. In graph 3, the function shows negative value entirely in the given interval.
4. In graph 4, the function exhibits both positive and negative value in the given interval and in not positive in the entire interval.
Thus, the function in graph 2 is positive for the entire interval [-3,-2].

Step-by-step explanation:
Danielle wants to translate triangle XYZ so that vertex Y is moved from coordinates (-
4,2) to (0,-3). Which of the following mappings can be used to find the new
coordinates of X and Z?
A (x,y)-( * - 4, y + 5)
B (x,y)-(x+4, y - 5)
C(x,y)-(x - 4, y + 3)
D(x,y)-(x + 5, y - 4)
Answer:
We need to use the mapping [tex]U'(x,y) = (x+4,y-5)[/tex] to find the new coordinates of X and Y.
Step-by-step explanation:
Vectorially speaking, we must look for the defintion of the translation operation such that vertex Y becomes vertex Y', which is represented by:
[tex]T(x,y) = Y'(x,y) - Y(x,y)[/tex] (1)
Where [tex]T(x,y)[/tex] is the translation vector.
If we know that [tex]Y(x,y) = (-4,2)[/tex] and [tex]Y'(x,y) = (0,-3)[/tex], then the translation vector is:
[tex]T(x,y) = (0,-3)-(-4,2)[/tex]
[tex]T(x,y) = (4, -5)[/tex]
If [tex]U(x,y) = (x,y)[/tex], [tex]T(x,y) = (4, -5)[/tex] and [tex]U'(x,y)[/tex] is the translated vector, then we obtain the following definition:
[tex]U'(x,y) = U(x,y) +T(x,y)[/tex] (2)
[tex]U'(x,y) = (x,y) + (4,-5)[/tex]
[tex]U'(x,y) = (x+4,y-5)[/tex]
The correct answer is B.

Parts of New Orleans lie 0.5 meter below sea level. After d days of rain, the equation w=0.3d ± 0.5 represents the water level w in meters. Find the zero, and explain what it means in the context of this situation.
Answer:
[tex]w = - 0.5[/tex]
Step-by-step explanation:
Given
[tex]w = 0.3d - 0.5[/tex] [The correct equation]
Required
Find and interpret the 0
To do this, we set [tex]d = 0[/tex]
Substitute 0 for d in [tex]w = 0.3d - 0.5[/tex]
[tex]w = 0.3 * 0 - 0.5[/tex]
[tex]w = 0 - 0.5[/tex]
[tex]w = - 0.5[/tex]
This means that the level of rain is 0.5m below the sea at day 0

A trapezoid with a top length of 4 cm and a bottom length of 14 cm. A right triangle is created in the trapezoid with a long leg length of 10 cm. a Triangle attached to the bottom of the trapezoid has height, when combined with the trapezoid, that measures at 18 cm.
Answer:
146
Step-by-step explanation:
Hey there to find the area of this shape we will divide it into 2 shapes first one is a trapezoid and the second one is a triangle. first, we find the area of a trapezoid. to find the area of a trapezoid we use the formula:
A = [tex]\frac{a+b}{2} * h[/tex]
in this situation
a = 4
b = 14
h = 10
Now we plug it into the formula which will look like:
A = [tex]\frac{4+14}{2}*10[/tex]
if we solve it:
4+14 = 18
18/2 = 9
9*10 = 90
so the area of the trapezoid is 90
Now we find the area of triangle. to find the area of a triangle we use the formula:
A = [tex]\frac{1}{2} * b * h[/tex]
in this situation
b = 14
h = 8 ( because the height of the trapezoid was 10 and the height of both shapes combined is 18 so we do 18 - 10 = 8 )
Now we put the numbers into the formula which will look like:
A = [tex]\frac{1}{2}*14*8[/tex]
if we solve it :
14*8 = 112
[tex]112*\frac{1}{2}[/tex] = 56
so the area of the triangle is 56
Now we add the area of both shapes:
56 + 90 = 146
area of the big shape = 146

The percentage of adults from this country who viewed a college education as essential for success x years after the first year can be represented by __.
Answer:
y = 31 + 2.6xStep-by-step explanation:
Initial percentage = 31%Average increase of percentage = 2.6% per yearThis can be represented as:
y = 31 + 2.6x,y- percentage after x years, x - number of years after the first year
