Answer:
39 hours
Step-by-step explanation:
First solve for how much Taylor would earn per hour which is to divide 203.40 by 9
= 203.40÷9 = 22.6
Let x represent the unknown hours
If 22.6 = 1 hr
Then 881.40 = x solving this simultaneously becomes
881.40 ÷ 22.6 = 39
x = 39, hence it'll take Taylor 39 hours to earn $881.40
She have to work 39 hours the next week to earn $881.40.
In simple terms, the unitary method is used to find the value of a single unit from a given multiple. For example, the price of 40 pens is Rs. 400, then how to find the value of one pen here. It can be done using the unitary method. Also, once we have found the value of a single unit, then we can calculate the value of the required units by multiplying the single value unit.
In 9 hours she earned $203.40
∴ In 1 hour she earned $203.40/9 = $22.6
Let number of hours she worked to earn $881.40 be x.
∴ x = $881.40/ $22.6
x = 39 hours
Thus she have to work 39 hours the next week to earn $881.40.

Identify the equation that describes the line in slope-intercept form slope = 3/4 point (2, 2) is on the line
Answer:
y = (3/4)x + 1/2
Step-by-step explanation:
the slope-intercept form is in general
y = ax + b
with a being the slope, and b the y-intercept (the y-value when x = 0).
because we got the slope and a point we can start with the point-slope form and then transform the equation.
the point-slope form is in general
y - y1 = a(x - x1)
a is again the slope (the same value), and (x1, y1) is a point on the line.
so,
y - 2 = 3/4 × (x - 2) = (3/4)x - 3/2
y = (3/4)x - 3/2 + 2 = (3/4)x - 3/2 + 4/2 = (3/4)x + 1/2
Which function displays this end behavior
- As x approaches negative infinity, y approaches positive infinity.
- As x approaches positive infinity, y approaches negative infinity.
Step-by-step explanation:
Since you haven't provided any functions, I can answer this question generally as to what the function would look like.
So when a polynomial has an even degree, then the two end behaviors will go in the same direction, and when it has an odd degree, then the two end behaviors will be in opposite directions. When a polynomial has a positive leading coefficient the right side will go towards infinity, and if a polynomial has a negative leading coefficient the right side will go towards negative infinity.
So let's look at the information:
As x approaches negative infinity, y approaches positive infinity.
Just given this we can't really say anything about the polynomial since we have to relate this to the right end behavior, or as x approaches infinity, so let's look at that.
As x approaches positive infinity, y approaches negative infinity.
This means that as x increases, y decreases, so that means the leading coefficient is negative. Since we know both end behaviors, and they're opposite (one y-value goes to negative infinity, and the other positive infinity), that means the polynomial is an odd degree.
So this means the polynomial will look something like this:
[tex]ax^n+bx^{n-1}+cx^{n-2}...[/tex]
where the leading coefficient "a" is negative and the degree of the polynomial (degree of leading coefficient) will be odd.

using graphing, what is the approximate solution of this equation?
3x[tex]3xx^{2} -6x-4=\frac{2}{x+3}+1[/tex]
Answer:
D. x ≈ 2.60
Step-by-step explanation:
The equation we have graphed is the one shown in the attachment. It is slightly different from the one in this problem statement.
Graphical solutionIt is often convenient to find a graphical solution to an equation by writing it in the form ...
f(x) = 0
Then the solutions are the x-intercepts of the graph, points that most graphing calculators can readily identify.
We have done this here by defining ...
[tex]y_1=3x^2-6x-4\\\\y_2=-\dfrac{2}{x+3}+1[/tex]
The graph is of y₁ -y₂. X-values where y₁-y₂ = 0 are solutions to the original equation, y₁ = y₂.
This equation is seen to have three solutions, approximately ...
x = {-3.05, -0.55, 2.60}
Of these, only x ≈ 2.60 is listed among the answer choices.
__
Additional comment
The value of y₁ -y₂ expressed in standard form is ...
[tex]3x^2-6x-4+\dfrac{2}{x+3}-1=0\\\\\dfrac{(x+3)(3x^2-6x-5)+2}{x+3}=0\\\\\dfrac{3x^3+3x^2-23x-13}{x+3}=0\\\\3x^3+3x^2-23x-13=0\quad(x\ne -3)[/tex]
The irrational solutions to this cubic can be found "exactly" by any of several applicable formulas. Numerical solutions are almost trivial to find with appropriate technology.

The answer choice which represents the domain and range of the function h(t) as given in the task content in which case, values are rounded to the nearest hundredth is; Domain: [0, 3.85] and Range: [0, 18.05].
What are the domain and range of the function as given in the task content?It follows from convention that the domain of a function simply refers to the set of all possible input values for that function.
Also, the range of a function is the set of all possible output values for such function.
On this note, by observing the graph in the attached image, it follows that the Domain of the function in discuss is; [0, 3.85].
While the range is the difference between the minimum and maximum height attained and can be computed as follows;
At minimum height, t = 0; hence, h(t) = 0.
At maximum height; h'(t) = 0 where h'(t) = h'(t)=-9.74t+18.75 and hence, t = 1.92.
Hence, h(1.92) = 18.05.
The range is therefore; [0, 18.05].

A boat sails on a bearing of 63 for 124 miles and then turns and sails 201 miles on a bearing of 192. Find the distance of the boat from its starting point.
The distance of the boat from its starting point is 156.226 .
According to the question
A boat sails on a bearing of 63 degree for 124 miles
i.e
By making 63 degree covers 124 miles
therefore ,
In figure below
AC = 124 miles
Then turns and sails 201 miles on a bearing of 192 degree
therefore ,
In figure below
CD = 201 miles
Now,
According to the sum of triangle
∠ACB + ∠ABC + ∠BAC = 180°
∠ACB + 90° + 63° = 180°
∠ACB = 27°
CE = 180° (Straight line )
therefore,
∠DCE = 192° - 180°
= 12°
As ∠C = 90°
therefore
∠ACD = ∠C - ∠DCE - ∠ACB
= 90° - 12°- 27 °
= 51°
Now,
The distance of the boat from its starting point = AD
By using Law of Cosines
As
The Law of Cosines can be used to find the unknown parts of an oblique triangle(non-right triangle), such that either the lengths of two sides and the measure of the included angle is known (SAS) or the lengths of the three sides (SSS) are given.
The Law of Cosines (also called the Cosine Rule) says:
c² = a² + b² − 2ab cos(C)
As we have 2 sides and one angle available we can use Law of Cosines
Therefore,
by substituting the value
(AD)² = (AC)² + (CD)² − 2(AC)(CD) cos(∠ACD)
(AD)² = (124)² + (201)² − 2*124*201 cos(51)
AD = 156.226
Hence, the distance of the boat from its starting point is 156.226 .

In my wallet, I have one-dollar bills, five-dollar bills, and ten-dollar bills. The total amount in my wallet is
$43. I have four times as many one-dollar bills as ten-dollar bills. Altogether, there are 13 bills in my wallet.
How many of each bill do I have?
Answer:
8 one-dollar bills
3 five-dollar bills
2 ten-dollar bills
Step-by-step explanation:
Let x = # of one-dollar bills, y = # of five-dollar bills, and z = # of ten-dollar bills. Total amount in the wallet is $43, so the first equation would be 1x + 5y + 10z = 43. Next, there are 4 times as many one-dollar bills as ten-dollar bills, so x = 4z. There are 13 bills in total, so x + y + z = 13
x + 5y + 10z = 43
x = 4z
x + y + z = 13
x + 5y + 10z = 43
x + 0y - 4z = 0
x + y + z = 13
5y + 14z = 43
-y - 5z = -13
5y + 14z = 43
-5y - 25z = -65
-11z = -22
z = 2
x = 4z
x = 4*2 = 8
x + y + z = 13
8 + y + 2 = 13
10 + y = 13
y = 3

Answer:
A ≈ 75 in²
Step-by-step explanation:
the area (A) of the circle is calculated as
A = πr² ( r is the radius )
here r = 5 and using 3 for π , then
A = 3 × 5² = 3 × 25 = 75 in²
Answer:
75 in^2
Step-by-step explanation:
Since the formula to find the area of a circle is already up, we can use that to solve the question.
The image gave us the value of the radius right away, so the question will be a lot easier to solve.
--> The reason why the radius is needed is that the 'r' in the formula means radius. We need the value of the radius to find the area of the circle.
Now, we can just replace r with 5.
--> A = 25 [tex]\pi[/tex]
Since the question told us to replace [tex]\pi[/tex] with 3, we can do that.
--> A = 25 x 3
--> A = 75
We can conclude that the area of the circle is 75 in^2.

What is the approximate radian measure
of an angle with a degree measure of
59.6°?
Answer:
The approximate radian measure of the angle. So we have 15 nine 0.6 degrees convert degrees to radiance. You have to multiply by pi over 1 80. So if we did that, that'd be 59.6 pi over 1 80. So if we want to know the approximate value, we're going to use the pi button on our calculator to figure out what 59.6 times pi is. That's approximately 187.2389, Divided by 1 80. So now I would divide that number by 180 and that gives me 1.04 radiance, 1.04 radiance is the answer.
