To buy a computer, Raquel borrowed $3,000 at 9%
simple interest for 4 years. How much money did she
have to pay back? (Hint: Combine both the principal and
simple interest for money she has to pay back).
Answer:
$4080
Step-by-step explanation:
We have the amount she will pay back, but first, we need to find the Interest accrued.
Simple Interest is given as:
[tex]I = \frac{P * R * T }{100}[/tex]
where P = principal
R = rate
T = time taken (in years)
Therefore, the interest on $3,000 at 9% simple interest for 4 years is:
[tex]I = \frac{3000 * 9 * 4}{100}[/tex]
I = $1080
Therefore, the amount she will pay back is:
$3000 + $1080 = $4080

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the distance between the maximum of a sine or cosine graph be A
Now , the maximum of sine graph is when θ = 90°
So , sin 90° = 1
The sine function ranges between -1 and 1, so the minimum is -1 and the maximum is 1
And , the maximum of cos graph is when θ = 360°
So , cos 360° = 1
Maximum value of cos θ is 1 when θ = 0˚, 360˚. Minimum value of cos θ is –1 when θ = 180 ˚.
Hence , amplitude represents half the distance between the maximum of a sine or cosine graph

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Let we suppose that:
The radius of circle A = C unitsThe radius of circle B = s units.Then we get:
Circumference of circle A = [tex]2\pi r \: \rm units[/tex]Circumference of circle B = [tex]2\pi s \: \rm units[/tex]As per the given information:
The circumference of a circle B is 80% of the circumference of circle A, or:
[tex]2\pi s \: \rm units[/tex] = 80% of [tex]2\pi r \: \rm units[/tex]
or:
[tex]2\pi s = \dfrac{2\pi r}{100} \times 80\\\\s = 0.8r \: \rm units[/tex]
Also, we have:
Area of circle A = [tex]\pi r^2 \: \rm units[/tex]Area of circle B = [tex]\pi s^2 \: \rm units[/tex]The rato of the area of the circle A to the area of the circle B is:
[tex]Area(A): Area(B) = \dfrac{\pi r^2}{\pi s^2} = \left( \dfrac{r}{s}\right)^2[/tex]
since we've got [tex]s= 0.8r[/tex], therefore,
[tex]Area(A): Area(B)= \left( \dfrac{r}{s}\right)^2 = \left(\dfrac{r}{0.8r}\right)^2 = \dfrac{100}{64} \\\\Area(A): Area(B)=\dfrac{100}{64} = 100:64[/tex]
Thus, the ratio of the area of circle A to the area of circle B for the considered circle A and B is 100:64

Does this represent a proportional relationship? Explain your answer. A specific shade of orange paint calls for 2 parts yellow and 3 parts red. Catie uses 3 cups of yellow paint and 4 cups of red paint to make orange paint.
Answer:
proportional relationship is not represented by them
Step-by-step explanation:
Ratio a/b and c/d are said to be proportional if a/b = c/d.
_________________________________________________
ratio of yellow part and red part for specific shade of orange =
2 part yellow/ 3 parts red = 2/3
____________________________________________________
ratio of yellow part and red part used by Catie =
3 cups of yellow/ 4 cups of red = 3/4
______________________________________
we have two ratio 2/3 and 3/4
but 2/3 is not equal to 3/4
hence , proportional relationship is not represented by them.

Amelia stars reading at 3: 25 and reads for 15 minute. What type of angle is formed by the hour and minute hands of the clock wen Amelia fineshes reading
Answer:
Step-by-step explanation:
If sh starts reading at 3:25 and reads for 15 minutes, she is finished at 3:40. The hour hand is on the 3 and the minute hand is on the 8, so there is a difference of 25 minutes between the hour hand and the minute hand. Each 5-minute increment is 30 degrees (360 / 12) so 30 x 5 = 150 degrees. This is an obtuse angle. Not sure what kind of an answer you're looking for so I gave both the degree measure of the angle formed by the hour hand and the minute hand, and the classification of the angle.
Answer:
90 degrees, which is a right angle
Step-by-step explanation:
The time indicates when she starts reading is irrelevant. The only thing to notice is that she reeds for 15 minutes. Whenever you read for 15 minutes the angle that is formed by the hour and minute hands of the clock will always be the same, regardless of the starting time!
60 minutes comes down to 360 degrees.
1 minute = 60/60 and that comes down to 360/60 = 6 degrees.
15 minutes = 15 times 1 minute....
15 minutes comes down to 15* 6 = 90 degrees
90 degrees is a right angle

Test whether the following functions are analytic exp(x).(cos y + i sin y)
Answer:
The given f(z) is analytic function
i) δU/δx = eˣ (cos y) = δV/δy
ii) δU/δy = eˣ (-sin y) = - δV/δx
Hence the CR - equations are satisfied
Step-by-step explanation:
Explanation:-
Analytic function:-
A point at which an analytic function ceases to posses a derivative is
called a singular point of the function.Thus the necessary and sufficient condition for a complex function f(Z) = U+i V is analytic in a region R are
δU/δx = δV/δy and δU/δy = -δV/δx ( C R equations)
Given f(Z) = eˣ(cos y+ i sin y)
Let U = eˣ(cos y) ....(i)
and
V = eˣ(sin y) ....(ii)
Differentiating equation(i) partially with respective to 'x'
δU/δx = eˣ (cos y)
Differentiating partially equation(i) with respective to 'y'
δU/δy = eˣ (-sin y)
Differentiating equation(ii) partially with respective to 'x'
δV/δx = eˣ (sin y)
Differentiating equation(ii) partially with respective to 'y'
δV/δy = eˣ (cos y)
Now
δU/δx = eˣ (cos y) = δV/δy
i) δU/δx = δV/δy
δU/δy = eˣ (-sin y) = - δV/δx
ii) δU/δy = - δV/δx
Hence the CR - equations are satisfied
There fore the given f(z) is analytic function

Topic: Percentage
Answer:
see below
Step-by-step explanation:
The total number of trees is
567+324+156+89+678 =1814
Percent fir = 567/1814 = .312568908=31.26 %
Percent pine = 324/1814 = .178610805=17.86%
Percent larch = 156/1814 =.085997795=8.60%
percent cedar = 89/1814 =.049062845=4.91%
Percent hemlock = 678/1814 = .373759647=37.38%
The total should be 100 %
31.26+17.86+8.60+4.91+37.38=100.01 ( rounding error because we rounded to the hundredths place)
Answer:
15A.)
1814 total trees
15B.)
Fir: 31.256890849%
Pine: 17.861080485%
Larch: 8.599779492%
Cedar: 4.906284454%
Hemlock: 37.375964718%
Step-by-step explanation:
15A.) For this first part, you would add all the trees together to get the total:
567+324+156+89+678 = ?
891+156+89+678 - Add 567 and 324 together.
1047+89+678 - Add 891 and 156 together.
1136+678 - Add 1136 and 678 together.
=1814 total trees
15B.) For this second part, you would divide each tree type (567, 324, 156, 89, 678) by the total trees (1814). To convert the decimal to a percent, you would move the decimal point to places to the right. Not sure how many decimal places you wanted for each percent, so I gave the full decimal for you to round as you please on your answer.
Fir: 567/1814 = 0.31256890849 = 31.256890849%
Pine: 324/1814 = 0.17861080485 = 17.861080485%
Larch: 156/1814 = 0.08599779492 = 8.599779492%
Cedar: 89/1814 = 0.04906284454 = 4.906284454%
Hemlock: 678/1814 = 0.37375964718 = 37.375964718%
