Answer:

The total interest paid by Nell in 20 years is $3,724.80

C is correct

Step-by-step explanation:

Nell took out a subsidized student loan of $6000 at a 4.8% APR, compounded  monthly.

First we find total amount in 10 months

[tex]A=6000(1+\frac{0.048}{12})^{10}[/tex]

[tex]A=6244.37[/tex]

Now, He has to pay loan off on 6244.37 for 20 years at 4.8% APR

Loan Formula:

[tex]P=\dfrac{PV\cdot r}{1-(1+r)^{-n}}[/tex]

PV=6244.37

r=0.048/12

n=240

[tex]P=\dfrac{6244.37\times \frac{0.048}{12}}{1-(1+\frac{0.048}{12})^{-240}}[/tex]

[tex]P=40.52[/tex]

Total pay in 20 years = 40.52 x 20 = 9724.80

Total amount took loan = $6000

Interest = 9724.80 - 6000

             = $3,724.80

Hence, The total interest paid by Nell in 20 years is $3,724.80

Answer:

Step-by-step explanation:

The percent of 64 which that is 16 is 25% because, to find what percent a number y is of a number x, you have to follow the steps: Divide y by x.

Answer:

25%

Step-by-step explanation:

The question aks: What percentage of 64 is 16?

Let that percentage be x,

[tex]\frac{x}{100}[/tex] of 64 = 16

We multiply both sides by 100 then divide by 64 to get:

x = [tex]\frac{1600}{64}[/tex] = 25%

Answer:

x = 4.  x = 64, d = 0.60.

Step-by-step explanation:

a. 256 /x = 64

64x = 256

x = 256/64

x = 4.

b.  256/x = 4

4x = 256

x = 256/4

x = 64.

c.  36/d = 60

60d = 36

d = 36/60

d = 0.60.

Answer:

2.11 ft

Step-by-step explanation:

Given in the question,

number of revolution a wheel make = 32

distance that wheel traveled while rotating  = 425ft

Step 1

Find the circumference of the wheel

circumference = total distance covered / number of revolution

                        = 425 / 32

                        = 13.28 ft

Step 2

Formula of circumference  

2πr = 13.28 ft

r  = 13.28/2π

r = 2.11 ft

The expression sin x / csc x + cos x / sec x simplifies to sin^2 x + cos^2 x by using the reciprocal identities of the trigonometric functions csc x and sec x.

The expression sin x / csc x + cos x / sec x can be simplified by substituting the reciprocal identities for the trigonometric functions csc x and sec x. The reciprocal of csc x is sin x and the reciprocal of sec x is cos x. Thus, sin x / csc x becomes sin x / (1/sin x) which simplifies to sin^2 x. Similarly, cos x / sec x becomes cos x / (1/cos x) or cos^2 x. Therefore, the simplified form of the expression is sin^2 x + cos^2 x.

B. 1184

Step-by-step explanation:

Answer is B

See photo

Answer:

16

Step-by-step explanation:

h(x) × h(x) = (6 - x)²

(h × h)(10) = (6 - 10)² = (- 4)² = 16

For this case we have by definition, that given two functions, then:

[tex](f * g) (x) = f (x) + g (x)[/tex]

Here, we want to find ([tex](h * h) (x):[/tex]

[tex](h * h) (x) = (6-x) (6-x)\\(h * h) (x) = 36-6x-6x + x ^ 2\\(h * h) (x) = 36-12x + x ^ 2[/tex]

We want to find the value of the function when [tex]x = 10[/tex].

[tex](h * h) (10) = 36-12 (10) + (10) ^ 2\\(h * h) (10) = 36-120 + 100\\(h * h) (x) = 16[/tex]

Answer: Obtion B

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

Step-by-step explanation:

The equation for exponential decay has the following form:

[tex]y = pe ^{-rt}[/tex]

Where

p is the initial population  

r is the rate of decrease

t is time.

In this problem we have to:

The current population of insect A to be 1.3 million and the current population of insect B to be 2.1 million.

So

[tex]p_1 = 1.3[/tex]  in millions

[tex]p_2 = 2.1[/tex]  in millions

We also need the populations of insect to be reduced at a rate of 3.8% and insect to be reduced at a rate of 4.6%.

so:

[tex]r_1 = 0.038\\\\r_2 = 0.046[/tex]

then the exponential decay equation for insect A is:

[tex]P = 1.3e ^ {-0.038t}[/tex]

the exponential decay equation for insect B is:

[tex]P = 2.1e ^ {-0.046t}[/tex]

Finally, the system of equations is:

[tex]P = 1.3e ^ {-0.038t}\\\\P = 2.1e ^ {-0.046t}[/tex]

The answer is the Option B

The domain of a function is the complete set of possible values of the independent variable.

The cosine function is represented by the expression: y=cos(x), where "x" is the independent function, and "y" the dependent function. So the domain comes to be all the values that "x" can take.

The domain of the cosine function is all the real numbers. All this can be verified by looking at its graph (attached)

Note that the reciprocal of tan B is by definition the cotangent (cot) of B:

   1                        adjacent side           BC

---------- = cot B = ----------------------- =  ---------

 tan B                   opposite side            AC

Answer:

Hence, The reciprocal of tan B is tan A

B is correct.

Step-by-step explanation:

We are given a right angle triangle. Right angle at ∠C

We need to find the reciprocal of tan B

First we write the formula of tan B using trigonometry identity.

[tex]\tan\theta=\dfrac{\text{Opposite}}{\text{Base}}[/tex]

In ΔABC, ∠C=90°

[tex]\tan B=\dfrac{AC}{BC}[/tex]

Now we reciprocal it.

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}[/tex]

[tex]\tan A=\dfrac{BC}{AC}[/tex]

Comparing both equation ( Right sides equal )

[tex]\dfrac{1}{\tan B}=\dfrac{BC}{AC}=\tan A[/tex]

[tex]\dfrac{1}{\tan B}=\tan A[/tex]

Hence, The reciprocal of tan B is tan A.

Final answer is $4440.

Step-by-step explanation:

Let amount of money invested in 8% stock = x

Let amount of money invested in 6% stock = y

then total money invested $325.6 gives equation

8% of x + 6% of y = 325.6

0.08x + 0.06y = 325.6

8x + 6y = 32560...(i)

other equation will be x=2y...(ii)

plug (ii) into (i)

8x + 6y = 32560

8(2y) + 6y = 32560

16y+ 6y = 32560

22y = 32560

[tex]y=\frac{32560}{22}[/tex]

y=1480

plug y=1480 into (ii)

x=2y=2(1480)=2960

Then total money invested in stocks = x+y= 1480+2960=4440

Hence final answer is $4440.

Answer:

-3/5

Step-by-step explanation:

you can use the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] to find the slope of a line when given two points.

we are given both the x and y intercepts, and we can use those in the formula.

the x intercept is (5,0) and the y intercept is (0,3)

i will treat (5,0) as my x1 and y1, and (0,3) as my x2 and y2

[tex]\frac{3-0}{0-5}[/tex] = -3/5

the slope is -3/5

The slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a line p:

The x-intercept of line p is 5 or (5, 0)

The y-intercept of line p is 3 or (0, 3)

The slope m can be evaluated:

[tex]\rm m =\dfrac{3-0}{0-5}[/tex]

m = -3/5

Thus, the slope of the line is -3/5 if the line p has an x-intercept of 5 and a y-intercept of 3.

Answer:

5.4 ft²

Step-by-step explanation:

Since the circle is inscribed in the square then radius r = 2.5

Area of yellow = area of square - area of circle

A = (5 × 5) - (π × 2.5²)

  = 25 - 6.25π ≈ 5.4 ft²

Answer:

Area of the Yellow Region is 5.4 ft²

Step-by-step explanation:

Given:

Length of the side of the square = 5 ft

Diameter of the Circle = Length of the side = 5 ft

⇒ Radius of the circle, r = 5/2 = 2.5 ft

To find: Area of the Yellow region from the figure.

Area of the Yellow Region = Area of the Square - Area of the Circle

                                            = Side × Side - πr²

                                            = 5 × 5 - 3.14 × (2.5)²

                                            = 25 - 3.14 × 6.25

                                            = 25 - 19.625

                                            = 5.375

                                            ≈ 5.4 ft²   (nearest tenth)

Therefore, Area of the Yellow Region is 5.4 ft²
