Answer:
Independent variable (x in 2D cartesian) = t (time)
Dependent variable (y in 2D cartesian) = p (battery power)
The independent variable is time.
The dependent variable is battery power.
Time is independent because it cannot be controlled.
Battery power is dependent because it can be controlled.
Since t is in hours,
The battery power begins at 100% and decreases 5% each hour.

Which graph represents the following piecewise defined function?
Answer: is B
Step-by-step explanation:
on edge 2020
The graph that represents the following piecewise defined function is graph D (Image attached).
What is piecewise defined function?A piecewise function is known to be a type of function that is known to be formed or created from scratch (pieces) of different functions over different intervals.
An example, a person can make a piecewise function f(x) where f(x) = -9 when -8 < x ≤ -4, f(x) = 5 when -4 < x ≤ -1, and f(x) = -6 when -1 <x ≤ 9. Looking at the graph attached, you can see that it tells us more about piecewise defined function.

Step-by-step explanation:
Find $m\angle1$ and $m\angle2$ .
Answer:
m<1 = 125°
m<2 = 55°
Step-by-step explanation:
Okay, so we're dealing with alternate interior angles and all that sorta stuff, so I'll try to explain it best I can, if I'm too confusing let me know, let's go:
So the angle labeled 125° and angle 1 are alternate interior angles, so they're equal (yes, we're ignoring the fact that that might not me right because the other line isn't straight, I don't have another solution okay) anyways, so that means that:
1 = 125°
Now we know what 1 and 2 are on the same plane or axis or something like that, so basically, 1 and 2 HAVE TO add up to 180°, so that means that:
125 + x = 180
And now we just have to do the inverse operations thing:
180 - 125 = 55
So, m<1 = 125° and m<2 = 55°
tell me if this is wrong so I can fix it
hope this helps:)
Which of the following functions have a domain of ( -infinity, infinity) and a range of
(-2, infinity)?
Check all that apply.
A. f(x) = 0.25^x- 2
B. f(x) = 0.25^x+2
c. f(x) = 3^x – 2
D. f(x) = 3^x +2
Answer:
It would be answers A and C
Step-by-step explanation:
Notice both end in negative 2, matching your range, so you can't get that correct using either B or D
The functions having domain (-∞,∞) and range (-2,∞) are f(x)=[tex]0.25^{x}-2[/tex] and f(x)=[tex]3^{x}-2[/tex].
What is function?A function is relationship between two or more variables expressed in equal to form .In a function each value of x must have a corresponding y value. The value of x is known as domain of the function and the value of y is known as range of function.
How to find function?We have been given four functions and we have to find the functions having domain (-∞,∞) and range (-2,∞).
Taking f(x)=[tex]0.25^{x}-2[/tex]
f(0)=1-2
=-1
f(1)=0.25-2
=-1.75
f(2)=0.50-2
=-1.50
f(-2)=1/0.50-2
=1-1/0.50
=0
So this function has domain (-∞,∞) and range (-2,∞) because the value of function increases from -2 as the value of x increases.
Taking f(x)=[tex]0.25^{x}+2[/tex]
Because the above function is opposite of the first function so it behaves opposite as the function.
Taking f(x)=[tex]3^{x} -2[/tex]
f(0)=1-2
=-1
f(1)=3-2
=1
f(-2)=1/9-2
=(1-18)/9
=-17/9
=-1.8
This function also has domain (-∞,∞) and range (-2,∞) because the value of increases from -2 as the value of x increases.
Next function is opposite from the third function so it behaves opposite to third function
Hence the functions having domain (-∞,∞) and range (-2,∞) are f(x)=[tex]0.25^{x}-2[/tex] and f(x)=[tex]3^{x}-2[/tex].

Suppose there are three routes from North Point to Boulder Creek, four routes from Boulder Creek to Beaver Dam, four routes from Beaver Dam to Star Lake, and two routes directly from Boulder Creek to Star Lake. (Hint: Draw a sketch. Assume each route can pass through a city at most one time.) (a) How many routes from North Point to Star Lake pass through Beaver Dam? To answer this question, think of creating a route from North Point to Star Lake that passes through Beaver Dam as a 3-step process. Step 1: Choose a route from North Point to Boulder Creek . Step 2: Choose a route from Boulder Creek to Beaver Dam. Step 3: Choose a route from Beaver Dam to Star Lake. There are choices for step 1, choices for step 2, and choices for step 3. Thus, the answer is . (b) How many routes from North Point to Star Lake bypass Beaver Dam?
Answer:
(a) 36 routes
(b) 6 routes
Step-by-step explanation:
Given
[tex]North\ Point \to Boulder\ Creek = 3[/tex]
[tex]Boulder\ Creek \to Beaver\ Dam = 4[/tex]
[tex]Beaver\ Dam \to Star\ Lake= 4[/tex]
[tex]Boulder\ Creek\to Star\ Lake= 2[/tex]
Solving (a): From [tex]North\ Point[/tex] to [tex]Star\ Lake[/tex] through [tex]Beaver\ Dam[/tex]
To do this, we consider the following routes;
[tex]North\ Point \to Boulder\ Creek \to Beaver\ Dam \to Star\ Lake[/tex]
Taking a pair of routes, we have:
[tex]North\ Point \to Boulder\ Creek = 3[/tex]
[tex]Boulder\ Creek \to Beaver\ Dam = 4[/tex]
[tex]Beaver\ Dam \to Star\ Lake= 4[/tex]
By multiplication route, we have:
[tex]Routes = 3 * 4 * 3[/tex]
[tex]Routes = 36[/tex]
(b) From [tex]North\ Point[/tex] to [tex]Star\ Lake[/tex] bypass [tex]Beaver\ Dam[/tex]?
To do this, we consider the following routes
[tex]North\ Point \to Boulder\ Creek \to Star\ Lake[/tex]
Taking a pair of routes, we have:
[tex]North\ Point \to Boulder\ Creek = 3[/tex]
[tex]Boulder\ Creek\to Star\ Lake= 2[/tex]
By multiplication rule, we have:
[tex]Routes = 3 * 2[/tex]
[tex]Routes = 6[/tex]

URGENT!!! Help pls. U could literally just give me the equations
Answer:
Step-by-step explanation:
Terminal points of vector u has been given as (4, 0), (9, 4).
Therefore, vector u can be represented by,
[tex]\vec{u}=\vec{u_2}-\vec{u_1}[/tex]
[tex]\vec{u}=(9i+4j)-(4i)[/tex]
[tex]\vec{u}=5i+4j[/tex]
And the magnitude of the vector u will be,
|| u || = [tex]\sqrt{5^2+4^2}[/tex]
= [tex]\sqrt{41}[/tex]
Slope of vector passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is defined by the expression,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Therefore, slope of vector u will be,
Slope = [tex]\frac{4-0}{9-4}[/tex]
= [tex]\frac{4}{5}[/tex]
Similarly, terminal points of vector v are (-7, 1) and (3, 9).
So the vector v will be,
[tex]\vec{v}=(3i+9j)-(-7i+1j)[/tex]
[tex]\vec{v}=(3i+7i)+(9j-1j)[/tex]
[tex]\vec{v}=10i+8j[/tex]
Therefore, magnitude of vector v will be,
|| v || = [tex]\sqrt{10^2+8^2}[/tex]
= [tex]\sqrt{164}[/tex]
= [tex]2\sqrt{41}[/tex]
Slope of vector v = [tex]\frac{9-1}{3+7}[/tex]
= [tex]\frac{8}{10}[/tex]
= [tex]\frac{4}{5}[/tex]
