Step-by-step explanation:

To find the circumference of a circle you use 2 · π · r

Answer:

x=−3 and y=4

Step-by-step explanation:

Multiply the first equation by -2,and multiply the second equation by 1.

−2(2x+5y=14)

1(4x+2y=−4)

Becomes:

−4x−10y=−28

4x+2y=−4

Add these equations to eliminate x:

−8y=−32

Then solve−8y=−32for y:

−8y=−32

−8y

−8

=

−32

−8

(Divide both sides by -8)

y=4

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2x+5y=14

Substitute4foryin2x+5y=14:

2x+(5)(4)=14

2x+20=14(Simplify both sides of the equation)

2x+20+−20=14+−20(Add -20 to both sides)

2x=−6

2x

(Divide both sides by 2)

Answer:

\(81 {d}^{4} {e}^{7} \)

Step-by-step explanation:

Use properties of degrees:

1. When multiplying different degrees on one term, the degree indicators must be multiplied, for example:

\(( { {x}^{2}) }^{3} = {x}^{2 \times 3} = {x}^{6} \)

2. When dividing like terms (with the same base) with different degrees, the degree indicators must be subtracted, for example:

\( \frac{ {x}^{5} }{ {x}^{2} } = {x}^{5 - 2} = {x}^{3} \)

3. When squaring a negative term in parentheses, the minus is eliminated, for example:

\(( { - 3x})^{2} = 9 {x}^{2} \)

.

\( \frac{ {(( { - 3d})^{2} \times {e}^{4} )}^{3} }{ {9d}^{2} \times {e}^{5} } = \frac{729 {d}^{6} \times {e}^{12} }{9 {d}^{2} \times {e}^{5} } = 81 {d}^{4} \times {e}^{7} \)

Amount borrowed by Stevie in the first year of college is $2500 and will repay in 24 months with $130.72 payments then total amount paid by Stevie is $3137.28 and finance charges are $637.28.

As given in the question,

Amount borrowed by Stevie in the first year of college is $2500

Number of months Stevie repay all the loan amount = 24 months

Payments paid each month = $130.72

Total amount paid by Stevie is equal to

= 24 × 130.72

= $3137.28

Finance charges paid by Stevie on his loan

= $3137.28 - $2500

= $637.28

Therefore, amount borrowed by Stevie in the first year of college is $2500 and will repay in 24 months with $130.72 payments then total amount paid by Stevie is $3137.28 and finance charges are $637.28.

Explanation:

Y is between X and Z (not necessarily at the midpoint). This means the three points are on the same line. Going from left to right we have X, Y and Z in that exact order.

Put another way, segment XZ is cut into smaller pieces XY and YZ.

The smaller pieces XY and YZ add back up to the largest segment XZ.

--------------

XY + YZ = XZ

( XY ) + ( YZ ) = XZ

( 7a ) + ( 5a ) = 6a+24 ..... substitution

7a+5a = 6a+24

12a = 6a+24

12a-6a = 24 ....... subtracting 6a from both sides

6a = 24

a = 24/6 ....... dividing both sides by 6

a = 4  is the first answer we're after

-------------

Use this value of 'a' to find the length of each segment

XY = 7a = 7*4 = 28

YZ = 5a = 5*4 = 20 is the second answer we want

XZ = 6a+24 = 6*4+24 = 48

Note how XY+YZ = 28+20 = 48 to match with XZ = 48 we got in the previous line above.

The number that represents 8 degrees warmer today than Monday is 0.

To find this, we can subtract 8 from the number that represents Monday's temperature.

Since Monday's temperature is not provided in the question, we cannot determine the exact number. However, out of the given options (-7, 0, 7, 14), the only number that is 8 degrees warmer than any other number is 0.

So, 0 represents the number that is 8 degrees warmer today than Monday.

Answer:

\(sec^2(x)\)

Step-by-step explanation:

The function that best approximates the given situation is sec²x.

We have to find

\(\lim_{h \to\00} \frac{tan(x+h)-tan x}{h}\)

Since the given expression reduces to 0/0 form when we apply the limits

So, let us apply the L'hospital rule

L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit.

So, after differentiating the numerator as well as the denominator of the given expression with respect to h we get

\(\lim_{h \to\00} \frac{sec^2(x+h)-0}{1}\)

\(= lim_{h \to\00} \frac{sec^2(x+0)}{1}\\\\= sec^2x\)

Therefore, the function that best approximates the given situation is sec²x.

Should be B.

There is a nested function structure. Let's first look at the limit of the interior (f(0)). The point we need to pay attention here is to look at the limits from the right and left. If both values are equal, we can say that it has a limit at that point.

If we express it algebraically;

The left limit and the right limit of \(f(0)\) are equal and equal to \(2.\)

The left limit and the right limit of f(2) are equal and equal to 3.

As I have drawn with colored arrows in the graph below, we approach from the left and from the right, and if they both point to the same point, we can talk about the existence of the limit at that point. Otherwise, this function does not have a limit at that point.

Answer:

Kyra is correct.

Step-by-step explanation:

Rational numbers;

All numbers which can be written in the form of \(\frac{p}{q}\) are rational numbers.

Example: 1, 2, \(\frac{1}{2}\), 1.414141....

Irrational numbers:

Numbers which are not in the form of \(\frac{p}{q}\) are irrational.

Example: 1.234, π, √2

So rational and irrational numbers are two separate things.

But all positive and negative numbers are real numbers.

Real numbers may be rational or irrational both.

Therefore, Kyra's interpretation is correct.

Therefore, the vector ⟨1,2⟩ of length 2 in the direction opposite to 4−13 is -4⟨1,2⟩/5.

The vector ⟨1,2⟩ of length 2 in the direction opposite to 4−13 is -4⟨1,2⟩/5.

Firstly, the magnitude of the vector, |v| is given as 2, i.e.|v| = 2

The vector whose direction is to be found is 4−13, i.e. ⟨4,-13⟩.

Let us represent the direction of vector 4−13 as a unit vector.

Step 1: Calculate |4−13|, which is the magnitude of the vector:|4−13|=√{(4)^2 + (-13)^2}=√{16 + 169}=√185

Step 2: Find the unit vector of 4−13 by dividing it with its magnitude: i.e., u⟨4,-13⟩ = 1/√185⟨4,-13⟩

Step 3: Scale the unit vector by multiplying it with the given magnitude 2, and multiplying it with -1 to get the opposite direction of the vector 4−13.

That is, v= -2 u⟨4,-13⟩= -2/√185⟨4,-13⟩

Multiplying both the numerator and the denominator by 2 gives the expression as -4⟨4, -13⟩/5 = ⟨-16/5, 52/5⟩.

Therefore, the vector ⟨1,2⟩ of length 2 in the direction opposite to 4−13 is -4⟨1,2⟩/5.

The values of a, b, c are 152°, 28°, 152° respectively.

Angles around a point describes the sum of angles that can be arranged together so that they form a full turn.

The sum of angles at a point will give 360°.

This means that a + b + c + 28 = 360

c +28 = 180° ( angle on a straight line)

c = 180 -28

c = 152°

c = a( alternate angles are equal)

therefore the value of a = 152°

b = 28( alternate angles are equal)

therefore the value of b is 28

therefore the values of a, b, c are 152°, 28°, 152° respectively

The payment necessary to amortize the given loan is $949.04.

1. To find the payment necessary to amortize the given loans using the amortization table, the steps are as follows:

The formula to calculate the payment for amortizing a loan is given by: \(`P = r(PV) / [1 - (1 + r)^(-n)]`\)

Where, P = Payment amount

r = Interest rate per compounding period

n = Total number of compounding periods`PV`

= The present value of the loan, i.e., the amount of the loan

For a semiannual payment, the interest rate and the number of years are calculated as:

\(`r = (6 / 2) / 100 \\=\\0.03`\)

(semiannual interest rate) and

\(`n = 8 x 2 \\= 16`\)

(total number of compounding periods)

Using the above values in the formula, we get:

\(P = 0.03 x 12000 / [1 - (1 + 0.03)^(-16)]\\≈ $949.04\)

(rounded to the nearest cent)

Therefore, the payment necessary to amortize the given loan is $949.04.

Therefore, the payment necessary to amortize the given loan is $949.04.
