Long-term purchase on a credit card better than taking out a loan when interest rate is 0% or very lower than loan, or any other benefits
Explanation:We can use a credit card for long term purchases if there is a 0% interest rate on purchase is allowing you to pay off your shopping with no additional cost for an introductory period. Or some of the credit cards may offer interest-free purchases for 3 to 6 months others can run for as long as 12 to 14 months. An interest-free period could be considered long-term if it lasts between 12 and 14 months or more.
We could benefit from one of these cards if you are making a large purchase and need more breathing room to pay it off without any interest. This is especially useful if you have a high spending period such as an overseas holiday coming up.
A long term purchase with loan or with a credit card will depends upon the interest rates offered in both the schemes.
In order to understand that what is more beneficial for us a long term purchase or taking out a loan we have to see the interest rates of the both the schemes.
If the interest rate of loan is higher than the interest rate offered by credit card then we must go for long term purchase on credit card and the amount can be paid later .
Also credit cards often offer other benefits too. These options can also be seen as a determining parameters of whether to take loan or a long term purchase on credit card is beneficial.
Also we can have a look at the period of interest free purchase offered by the credit card.
Depending upon the credit card and its usage they can vary from three months to one year with multiple other benefits which promote the use of credit card.
so we can conclude that
A long term purchase with loan or with a credit card will depends upon the interest rates offered in both the schemes.

y = -1/4x + 2 and 2y = 1/2x - 4
how do these lines compare?
1. Slopes:
- The first line has a negative slope of -1/4.
- The second line has a positive slope of 1/4.
2. Y-intercepts:
- The first line intersects the y-axis at y = 2.
- The second line intersects the y-axis at y = -2.
To compare these lines, let's first rewrite both equations in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.
1. For the first equation, [tex]\( Y = -\frac{1}{4}x + 2 \)[/tex]:
- Slope (m₁) = -1/4
- Y-intercept (b₁) = 2
2. For the second equation, [tex]\( 2y = \frac{1}{2}x - 4 \)[/tex]:
- We divide both sides by 2 to isolate y:
[tex]\( y = \frac{1}{4}x - 2 \)[/tex]
- Slope (m₂) = 1/4
- Y-intercept (b₂) = -2
Now, let's compare:

When Amy roller-skates, she moves 110 yards per minute. What is her speed in miles per hour? Round your answer to the nearest hundredth. (Hint: 1 yd= 3 ft; 5280 ft = 1 yd.; 60 min= 1 hr)
Answer:
Speed of Amy is 3.75 miles per hour.
Step-by-step explanation:
We have, speed of Amy = 110 yards per minute
This means, she covers 110 yards of distance in 1 minute.
Now, to convert the speed of Amy into miles per hour, we will first convert the distance from yards into miles and then convert time from minutes to hour.
We know that,
1 yard = 3 feet
∴ 110 yards = 3 × 110 feet = 330 feet
Now, we also know that,
5280 feet = 1 mile
∴ 1 feet = [tex]\frac{1}{5280}[/tex] miles
So, 330 feet = [tex]\frac{1}{5280}\times330[/tex] = [tex]\frac{1}{16}[/tex] miles
∴ 110 yards = 330 feet = [tex]\frac{1}{16}[/tex] miles
Now, 60 min = 1 hr
∴ 1 min = [tex]\frac{1}{60}[/tex] hrs
So, 110 yards = [tex]\frac{1}{16}[/tex] miles and 1 min = [tex]\frac{1}{60}[/tex] hr
So, we can say that, Amy covers a distance of [tex]\frac{1}{16}[/tex] miles in
[tex]\frac{1}{60}[/tex] hr.
We know that,
[tex]speed=\frac{distance}{time}[/tex]
[tex]speed=\frac{(\frac{1}{16}) miles}{(\frac{1}{60})hr}[/tex]
[tex]speed=\frac{60}{16} miles/hr = 3.75 miles/hr[/tex]
Therefore, the speed of Amy in miles/hr is 3.75 miles/hr.
given the list of ordered pairs, what is the x intercept (8,10),(3,-4),(0,8),(4,-3),(9,0)
Answer:
The x-intercept is the ordered pair (9,0)
Step-by-step explanation:
we know that
The x-intercept is the value of x when the value of y is equal to zero
so
The x-intercept is a ordered pair with a y-coordinate equal to zero
therefore
In this problem
The x-intercept is the ordered pair (9,0)
The x-intercept from the list of ordered pairs (8,10), (3,-4), (0,8), (4,-3), (9,0) is 9, as it is the x-value of the pair where the y-coordinate is zero.
Explanation:To find the x-intercept from a list of ordered pairs, you need to look for the pair where the y-coordinate is zero. The x-intercept is the x-value in this pair.
From the list of ordered pairs given in the question, which are (8,10), (3,-4), (0,8), (4,-3), (9,0), we identify that the x-intercept is in the pair where y is equal to 0.
Thus, the x-intercept from the list is 9, as it appears in the ordered pair (9,0).
A light bulb consumes 5280 watt hours in 5 days and 12 hours, How many watt-hours does it consume per day?
Il watt-hours per day
|
*
$
?
The correct answer is:
The light bulb consumes 1056 watt-hours per day, calculated by dividing the total watt-hours by the total number of days.
To find out how many watt-hours the light bulb consumes per day, we need to divide the total watt-hours consumed by the total number of days.
Given:
- Total watt-hours consumed = 5280 watt-hours
- Total time = 5 days and 12 hours
First, let's convert the total time to hours:
[tex]\[ \text{Total time} = 5 \times 24 \text{ hours} + 12 \text{ hours} = 120 + 12 = 132 \text{ hours} \][/tex]
Now, we can calculate the watt-hours consumed per day:
[tex]\[ \text{Watt-hours per day} = \frac{\text{Total watt-hours}}{\text{Total number of days}} \]\[ \text{Watt-hours per day} = \frac{5280 \text{ watt-hours}}{5 \text{ days}} \]\[ \text{Watt-hours per day} = \frac{5280}{5} \text{ watt-hours} \]\[ \text{Watt-hours per day} = 1056 \text{ watt-hours} \][/tex]
So, the light bulb consumes 1056 watt-hours per day.

Identify corresponding sides RGK=MQB
Final answer:
In geometry, corresponding sides are sides that have the same relative position in two similar figures. To identify the corresponding sides in the given question, we need to find the sides with the same position in the figures RGK and MQB. The corresponding sides of RGK and MQB are RG = MQ, RK = MB, and GK = QB.
Explanation:
In geometry, corresponding sides are sides that have the same relative position in two similar figures. To identify the corresponding sides in the given question, we need to find the sides with the same position in the figures RGK and MQB.
In this case, RGK and MQB are both triangles, so we need to compare their corresponding sides. The corresponding sides of a triangle are the sides that are in the same position (opposite vertices) in the two triangles.
Therefore, the corresponding sides of RGK and MQB are:
RG = MQ
RK = MB
GK = QB

Note: As you missed to identify what we have to find in this question. But, after a little research, I am able to find that we had to find the Mode for the data given in your question. So, I am assuming we have to calculate the the Mode. Hopefully, it would clear your concept regarding this topic.
Answer:
The mode of the data = 75
Step-by-step explanation:
Lets visualize the given data in a table to show the frequency distribution:
Daily expenditure on milk (in Rs) Number of households
0-30 5
30-60 6
60-90 9
90-120 6
120-150 4
Here the maximum frequency is 9.
So, modal class is 60-90.
As the formula to calculate the mode:
[tex]Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )[/tex]
Here, the maximum
[tex]l_{1} =60, f_{1} =9, f_{0}=6, f_{0}=6, h=30[/tex]
[tex]l=[/tex] is the lower limit of the class
[tex]f_{1} =[/tex] is the frequency of the modal class
[tex]f_{0} =[/tex] is the frequency of the previous modal class
[tex]f_{2} =[/tex] is the frequency of the next previous modal class
[tex]l=[/tex] is the class size
So,
[tex]Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )[/tex]
[tex]Mode = 60 + 30 (\frac{9-6}{2(9)-6-6} )[/tex]
[tex]Mode = 60 + \frac{(30)(3)}{6}[/tex]
[tex]Mode = 60 + 15=75[/tex]
∴ The mode of the data = 75

verify rolles theorem for f(x) =x^3-x^2-6x+2 in [0,3]
Answer:
See the explanation.
Step-by-step explanation:
Given function [tex]f(x)=x^3-x^2-6x+2[/tex]
And the interval [tex][0,3][/tex]
According to Rolle's Theorem
Let [tex]f(x)[/tex] be differentiable on the open interval [tex](a,b)[/tex] and continuous on the closed interval [tex][a,b][/tex]. Then if [tex]f(a)=f(b)[/tex], then there is at least one point [tex]x\ in\ (a,b)[/tex] where [tex]f'(x)=0[/tex].
So,
[tex]f(0)=0^3-0^2-6\times0+2\\\\f(0)=2\\\\Similarly\\\\f(3)=3^3-3^2-6\times3+2\\\\f(3)=27-9-18+2\\\\f(3)=2\\\\We\ can\ see\ f(0)=f(3)\\\\Now,\\\\f'(x)=\frac{d}{dx}(x^3-x^2-6x+2)\\\\f'(x)=3x^2-2x-6\\\\put\ f'(x)=0\\\\3x^2-2x-6=0\\[/tex]
We will find the value of [tex]x[/tex] for which [tex]f'(x)[/tex] became zero.
[tex]If\ ax^2+bx+c=0\\\\Then,\ x_{1}=\frac{-b+\sqrt{b^2-4ac}}{2a}\\ \\And\ x_{2}=\frac{-b-\sqrt{b^2-4ac}}{2a}\\\\f'(x)=3x^2-2x+6=0\\a=3,\ b=-2,\ c=6\\\\\ x_{1}=\frac{-(-2)+\sqrt{(-2)^2-4\times3\times(-6)}}{2\times3}\\\\x_{1}=\frac{2+\sqrt{76}}{6}=\frac{2+2\sqrt{19}}{6}\\\\x_{1}=\frac{1+\sqrt{19}}{3}\\\\x_{2}=\frac{-(-2)-\sqrt{(-2)^2-4\times3\times(-6)}}{2\times3}\\\\x_{1}=\frac{2-\sqrt{76}}{6}=\frac{2-2\sqrt{19}}{6}\\\\x_{2}=\frac{1-\sqrt{19}}{3}[/tex]
We can see
[tex]x_{1}=\frac{1+\sqrt{19}}{3}=1.786\\\\and\ 1.786\ is\ in\ [0,3][/tex]
There is at least one point [tex]1.786\ in\ (0,3)[/tex] where [tex]f'(x)=0[/tex].
Rolle's theorem requires a function to be continuous on [a, b], differentiable on (a, b), and have f(a) = f(b). After verifying these conditions are met for f(x) = x^3 - x^2 - 6x + 2, we look for a point in (0, 3) where f'(x) = 0. We cannot find such a point in the interval, suggesting an error in the application of the theorem.
To verify Rolle's theorem for the function f(x) = x^3 - x^2 - 6x + 2 in the interval [0,3], we need to ensure that the function meets the criteria stated by the theorem:
The function f must be continuous on the closed interval [a, b].
The function f must be differentiable on the open interval (a, b).
The function f must satisfy f(a) = f(b).
f(x) = x^3 - x^2 - 6x + 2 is a polynomial, which is continuous and differentiable everywhere. Therefore, it satisfies the first two conditions of Rolle's theorem on any interval, including [0,3].
Now we need to check the third condition:
f(0) = (0)^3 - (0)^2 - 6(0) + 2 = 2
f(3) = (3)^3 - (3)^2 - 6(3) + 2 = 2
Since f(0) = f(3), the third condition is also met. Hence, Rolle's theorem applies, and there must be at least one c in (0, 3) such that f'(c) = 0.
To find c, we take the derivative of f(x):
f'(x) = 3x^2 - 2x - 6
Set f'(x) equal to zero and solve for x:
3x^2 - 2x - 6 = 0
Factors into (3x + 2)(x - 3) = 0
So x can be either x = -2/3 or x = 3. Since -2/3 is not in our interval, the only possibility in the interval (0, 3) is at x = 3. However, in this case, the point x = 3 is an endpoint, hence it's not within the open interval (0, 3).
Thus, we need to conclude that there has been a mistake, as x = 3 does not satisfy the condition for Rolle's theorem within the open interval (0, 3).

If cos x = sin(20 + x) ° and 0°
Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
Answer:
x = 35°
Step-by-step explanation:
The question is as following
cos x = sin(20 + x)° and 0° < x < 90° , find X?
==============================================
cos x = sin(20 + x)°
sin and cos are co-functions,
which means that: cos x = cos [90 - (20 + x)]
∴ x = 70 - x
∴ 2x = 70
∴ x = 35°
======================
Note: cos θ = sin ( 90 - θ )
Calculate the cost of spraying a rectangular field 720 m by 500 m with a pesticide at a cost of $23.50 per hectare.
The calculated cost of spraying the rectangular field is $846
Calculating the cost of spraying the rectangular field
From the question, we have the following parameters that can be used in our computation:
Dimension = 720 m by 500 m
Unit cost = $23.50 per hectare
The area of the field is calculated as
Area = 720 m * 500 m
So, we have
Area = 360000 square meters
Converted to hectares, we have
Area = 36 hectares
So, we have
Cost = $23.50 per hectare * 36 hectares
Evaluate
Cost = $846
Hence, the cost of spraying the rectangular field is $846

Hence, the vertex of the function is at point [tex]\left(\dfrac{5}{2},\dfrac{49}{2}\right).[/tex]
The axis of symmetry of the function is vertical line which passes through the vertex, so its equation is
[tex]x=\dfrac{5}{2}[/tex]
To find y-intercept, equat t to 0 and find h:
[tex]h=-2\cdot 0^2+10\cdot 0+12=12[/tex]
Hence, y-intercept is at point (0,12)
To find the roots of the quadratic finction, equate h to 0 and solve the equation for t:
[tex]h=0\Rightarrow -2t^2+10t+12=0\\ \\t^2-5t-6=0\ [\text{Divided by -2}]\\ \\D=(-5)^2-4\cdot 1\cdot (-6)=25+24=49\\ \\t_{1,2}=\dfrac{-(-5)\pm \sqrt{49}}{2\cdot 1}=\dfrac{5\pm 7}{2}=6,\ -1[/tex]
Therefore, two roots are [tex]t_1=-1[/tex] and [tex]t_2=6[/tex]

Answer:
Angle bisector
Step-by-step explanation:
Find the measure of the angle COA. By angle addition postulate,
[tex]m\angle COX=m\angle AOX+m\angle COA[/tex]
From the diagram,
[tex]m\angle COX=80^{\circ}\\ \\m\angle AOX=40^{\circ},[/tex]
then
[tex]80^{\circ}=m\angle COA+40^{\circ}\\ \\m\angle COA=80^{\circ}-40^{\circ}=40^{\circ}[/tex]
Find the measure of the angle BOA. By angle addition postulate,
[tex]m\angle BOX=m\angle AOX+m\angle BOA[/tex]
From the diagram,
[tex]m\angle BOX=60^{\circ}\\ \\m\angle AOX=40^{\circ},[/tex]
then
[tex]60^{\circ}=m\angle BOA+40^{\circ}\\ \\m\angle BOA=60^{\circ}-40^{\circ}=20^{\circ}[/tex]
Find the measure of the angle COB. By angle addition postulate,
[tex]m\angle COX=m\angle BOX+m\angle COB[/tex]
From the diagram,
[tex]m\angle BOX=60^{\circ}\\ \\m\angle COX=80^{\circ},[/tex]
then
[tex]80^{\circ}=m\angle COB+60^{\circ}\\ \\m\angle COB=80^{\circ}-60^{\circ}=20^{\circ}[/tex]
This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA
Which function has a domain of x 25 and a range of y s3?
g= x-5+3
9 = x+5 -3
y=-x-5+3
y=-x+5 -3
Answer:
[tex]y = - \sqrt{x - 5} + 3[/tex]
Step-by-step explanation:
The function [tex]y = - \sqrt{x - 5} + 3[/tex] has a domain x ≥ 5.
This is because the function remains real for (x - 5) ≥ 0 as negative within the square root is imaginary.
Hence, (x - 5) ≥ 0
⇒ x ≥ 5
Now, for all x values that are greater than equal to 5 the value of [tex]- \sqrt{x - 5}[/tex] will be negative.
So, [tex]- \sqrt{x - 5} \leq 0[/tex]
⇒ [tex]- \sqrt{x - 5} + 3 \leq 3[/tex]
⇒ y ≤ 3
Therefore, the range of the function is y ≤ 3. (Answer)
1. Find the equation of the line that is modeled by the values in the table shown below.
A table is given containing the values of x and y.
The equation of the line is modeled by the values in the table.
As we can see in the table, we get to know that;
The y value is increased by 5 whereas the value of x is increased by 2.
So, we will put the numbers over each other for slope.
Therefore, slope=5/2
Now, we will put the slope value in the model equation;
y=mx+b
y=5/2x+b
Now, in the place of y and x we will be putting (2,1) in their place;
1=5/2(2)+b
b=1-5=-4
So, the final equation we get as;
y=5/2x-4
Hence, the equation of the line that is modeled by the values in the table shown is y=5/2x-4.
