I think 40/3 is the answer you’re looking for.

Answer:

A = Rate of change is y = 4x

This is because it is set up as y/x and for the graph B = y = 3x.

Function A is greater in change than Function B

Because if you substitute x for 1.

A would be 4.

B would be 3.

The annual effective interest rate is 8%, the present value of the annuity,

is option C: $1,367.77

To calculate the present value of the annuity, we can use the formula for the present value of a series of periodic payments:

\(\[ PV = PMT \times \left(1 - (1 + r)^{-n}\right) / r \]\)

Where:

- PV is the present value of the annuity,

- PMT is the payment amount,

- r is the interest rate per compounding period, and

- n is the total number of compounding periods.

In this case, Paul will receive payments of $50 every three months for 10 years, which is a total of 40 payments (since there are 4 quarters in a year and 10 years equals 40 quarters).

The interest rate is 8% per year, so we need to adjust it for the compounding period. Since the payments are made every three months, the interest rate per quarter is 8% divided by 4, which is 2%.

However, since the first payment will be made 3 months from today, we need to discount the first payment by the interest earned during that period. To do this, we calculate the present value of the first payment using the formula:

\(\[ PV_1 = PMT \times (1 + r)^{-1} \]\)

Substituting the values, we have:

\(\[ PV_1 = 50 \times (1 + 0.02)^{-1} \approx 49.0196 \]\)

Now, we can calculate the present value of the remaining annuity payments using the adjusted interest rate and the total number of periods (39 remaining payments):

\(\[ PV = 50 \times \left(1 - (1 + 0.02)^{-39}\right) / 0.02 \approx 1,367.77 \]\)

Therefore, the correct answer is option C: $1,367.77.

The trigonometric simplified form of sinθ secθ is tanθ.

To write the trigonometric expression sinθ secθ in terms of sine and cosine, we can use the reciprocal identity for secant:

secθ = 1/cosθ

Substituting this into the expression, we have:

sinθ secθ = sinθ (1/cosθ)

Now, to simplify the expression, we can multiply sinθ by 1/cosθ:

sinθ (1/cosθ) = sinθ/cosθ

Using the quotient identity for tangent, we can rewrite sinθ/cosθ as tanθ:

sinθ/cosθ = tanθ

Therefore, the simplified form of sinθ secθ is tanθ.

Answer:

D

Step-by-step explanation:

Proportional relationships go through the origin on the graph so we can eliminate A and B. Also the x and y coordinates have the same ratio so the answer is D because 2:3 = 4:6 = 8:12 = 12:18.

The graph of y=3x^4-16x^3+24x^2+48 is concave down for x values greater than or equal to 0.

The graph of y=3x^4-16x^3+24x^2+48 is an example of a polynomial function. To determine the concavity of a polynomial function, we must first identify the intervals where the function is increasing and decreasing. In this case, the function is increasing for all x values greater than or equal to 0.

Next, we must find the second derivative and determine the intervals where the second derivative is negative. If the second derivative is negative, then the graph is concave down. For this polynomial, the second derivative is y'' = -48x + 48, which is negative for all x values greater than or equal to 0. This means that the graph of y=3x^4-16x^3+24x^2+48 is concave down for all x values greater than or equal to 0.

Answer: moderate, C, B

Step-by-step explanation:

A)  A shows a moderate negative correlation.  It is moderate because the scattered points are sort of close to the line so it has moderate/medium correlation.  It is also negative because it has a negative slope

B) C shows the strongest correlation because the points around the line are tight and close.

C)  B should not have been drawn.  The  correlation is very weak.  You do know where the line should be because the points are all over the place.

The statements that is true about the similarity of the two triangles the option D

D. ΔMNO and ΔJKL are not similar triangles

Similar triangles are triangles which have proportional corresponding sides

The parameters in the question are;

The length of segment MN = 20

Length of segment NO = 12

Length of segment OM = 25

Measure of angle ∠O = 56°

Length of segment LJ =- 15

Length of segment JK = 12

Length of segment KL = 9

Measure of angle ∠L = 56°

Two triangles are similar if the ratio of two sides on one triangle are proportional to two sides of another triangle, and the included  angle between the two sides are congruent

The included angle between sides ON and MO on triangle MNO is congruent to the included angle between segment LK and JL in triangle JKL

True, when nesting loops, the inner loop must be completely contained within the outer loop and must use a different control variable.

When nesting loops, one loop is placed inside another loop. The purpose of nesting loops is to execute a set of instructions repeatedly in a structured manner. In this context, the statement is true: the inner loop must be entirely contained within the outer loop, and a different control variable must be used for each loop.

By containing the inner loop within the outer loop, we ensure that the inner loop executes its iterations every time the outer loop iterates. This nested structure allows for more complex and detailed looping patterns.

Using different control variables for the inner and outer loops is necessary to maintain independent control over their iterations. Each loop should have its own variable to track and control its progress. This distinction is crucial in preventing conflicts and ensuring that the loops function as intended.

Therefore, when nesting loops, it is essential to follow these guidelines: the inner loop must be entirely contained within the outer loop, and a distinct control variable should be used for each loop to ensure proper execution and avoid potential errors.

Answer:

y + 1 = \(\frac{1}{2}\) (x + 2)

Step-by-step explanation:

The equation of a line in point- slope form is

y - y₁ = m(x - x₁)

where m is the slope and (x₁, y₁ ) a point on the line

Calculate m using the slope formula

m = \(\frac{y_{2}-y_{1} }{x_{2}-x_{1} }\)

with (x₁, y₁ ) =(- 2, - 1) and (x₂, y₂ ) = (2, 1) ← 2 points on the line

m = \(\frac{1+1}{2+2}\) = \(\frac{2}{4}\) = \(\frac{1}{2}\)

with point on line (x₁, y₁ ) = (- 2, - 1 ), then

y - (- 1) = \(\frac{1}{2}\) (x - (- 2) ), that is

y + 1 = \(\frac{1}{2}\)(x + 2) ← equation of line

Answer:

x =127

Step-by-step explanation:

Since this is a 6 sided figure, the sum of the interior angles is 720

128+133+112+x+120+100 = 720

Combine like terms

x+593=720

Subtract 593 from each side

x+593-593 = 720-593

x =127

Hint :

Sum of angles of the 6 sided figure = \( {720}^{o} \)

Answer:

\( {x}^{o} = {127}^{o} \)

Step-by-step explanation:

\( {x}^{o} + {112}^{o} + {133}^{o} + {128}^{o} + {100}^{o} + {120}^{o} = {720}^{o} \\ {x}^{o} + {593}^{o} = {720}^{o} \\ {x}^{o} = {720}^{o} - {593}^{o} \\ {x}^{o} = { 127}^{o} \)
