4x^2 - x - 67y + 146 = 0
x - y = 2

Answers

Answer:

(7,5) and (10,8)

Step-by-step explanation:

x = y+2

4(y+2)^2 -(y+2) - 67y + 146 = 0


4(y^2+4+4y) -y - 2 - 67y + 146 = 0

4y^2+16y+16 - 68y + 144 = 0

4y^2 -52y + 160= 0

y^2 - 13y+40 = 0

(y-8)(y-5) = 0

y = 8

y = 5


x = 5+2 = 7

x = 8 + 2 = 10

Find the general indefinite integral. (Use C for the constant of integration.) ∫6√x7​dx Evaluate the integral by making the given substitution. (Use C for the constant of integration.) ∫x2√x3+39​dx,u=x3+39.

Answers

The general indefinite integral of 6 \(\sqrt{(x^7)}\ is\ 4/15(x^15/2) + C\). By making the substitution u = x^3 + 39, the integral of \(x^2\sqrt{(x^3 + 39)}\) dx becomes 1/9\((u^{2/3})\) + C.

To find the general indefinite integral of 6\(\sqrt{(x^7)}\), we can use the power rule for integration, which states that ∫\(x^n\) dx = \((1/(n+1))x^{n+1} + C\), where C is the constant of integration. Applying this rule, we have ∫6\(\sqrt{(x^7)}\) dx = 6∫\((x^7)^{1/2}\) dx = 6 * (2/9)\((x^{7/2})\) + C = 4/15\((x^{15/2})\) + C.

Now, let's evaluate the integral ∫x^2√(x^3 + 39) dx by making the substitution u = \(x^3\) + 39. Taking the derivative of u with respect to x gives du/dx = \(3x^2\). Rearranging this equation, we have dx = (1/3x^2) du. Substituting this back into the integral, we get ∫\(x^2\sqrt{(x^3 + 39)}\) dx = ∫\((x^2)(u^{1/2}) * (1/3x^2)\) du = (1/3)∫\(u^{1/2}\) du.

Integrating u^(1/2) with respect to u using the power rule, we have (1/3) * \((2/3)(u^{3/2}) + C = 2/9(u^{2/3}) + C\). Substituting back u = x^3 + 39, the final result is \(2/9(x^3 + 39)^{2/3} + C\).

Does tripling the length of time for the investment double the interest earned with
compound?

Answers

No, tripling the length of time for the investment does not double the interest earned with compound interest.

Explaining if tripling the length double the interest

When interest is compounded, the interest earned depends not only on the length of time, but also on the interest rate and the number of compounding periods.

For example, if an investment of $100 earns 5% annual interest compounded annually for 1 year, the interest earned would be:

Interest = $100 x 0.05 = $5

If the same investment is compounded for 2 years instead of 1, the interest earned would be:

Interest = $100 x (1 + 0.05)^2 - $100 = $10.25

As we can see, doubling the length of time for the investment does not double the interest earned with compound interest.

The interest earned depends on the interest rate and the number of compounding periods as well.

12 people fit comfortably in a 5 x 5 foot square.use this value to estimate of a crowd that is 10 feet deep on both sides of the street along a 1 mil section of a parade route

Answers

Answer:

48 people

Step-by-step explanation:

It states that 12 people fit into a 5 x 5 ft² area.

Here, we are given the length and breath of the side, both 5 ft. And from that, we can estimate the area of the place.

Area of a square is gotten by multiplying both sides together, and thus

5 * 5 = 25 ft²

We are told 12 people fit into 25 ft². In order to get the number of people that fit a 10 x 10, we first need to calculate the area.

We already have the length and breadth to be 10 ft each, so

Area = 10 * 10 = 100 ft²

Now, we calculate.

If

12 people fit into 25 ft²

x people will fit into 100 ft²

If we cross multiply, we have

1200 = 25x

We then divide both sides by 25

x = 1200 / 25

x = 48

Therefore, 48 people will fit into a 10 x 10 ft area

Answer:

a. El lado restante = 16 cm.

b. El lado restante = √7 cm

c. El lado restante = 6·√13 cm

Step-by-step explanation:

Debemos calcular la dimensión del otro lado del volante de la siguiente manera;

a. La diagonal = 34 cm

Longitud de un lado = 30 cm

Por lo tanto, según el teorema de Pitágoras, la longitud del lado restante viene dada por la siguiente relación

La longitud del lado restante = √ ((Diagonal) ² - (Longitud del lado dada) ²)

La longitud del lado restante = √ ((34) ² - (30) ²) = 16 cm

El lado restante = 16 cm.

b. La longitud del lado restante = √ ((Diagonal) ² - (Longitud del lado dada) ²)

La longitud del lado restante = √ ((4) ² - (3) ²) = √7 cm

El lado restante = √7 cm

C. La longitud del lado restante = √ ((Diagonal) ² - (Longitud del lado dada) ²)

La longitud del lado restante = √ ((18) ² - (12) ²) = 6·√13 cm

El lado restante = 6·√13 cm.

7700 dollars is placed in an account with an annual interest rate of 5.5%. To the nearest year, how long will it take for the account value to reach 26500 dollars?

Answers

116 years it take  for the account value to reach 26500 dollars

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that 7700 dollars is placed in an account with an annual interest rate of 5.5%.

We need to find the time it  take for the account value to reach 26500 dollars

\(A=P(1+r)^{t}\)

A = final amount=26500

P = initial amount (7700)

r = annual interest rate (5.5%)

n = number of times interest is compounded per year

t = time in years

Solving for t, we get:

\(25600=7700(1+5.5/100)^{t}\)

\(25600=7700(1.055)^{t}\)

Divide both sides by 7700

\(25600/7700=1.055^{t}\)

3.32=tlog1.055

3.32=0.02t

t=116 years

Hence, 116 years it take  for the account value to reach 26500 dollars

Answers

To determine if two triangles are congruent, the following conditions must be met:

All corresponding pairs of vertical angles are equal.All corresponding pairs of alternate interior angles are equal.All corresponding pairs of alternate exterior angles are equal.All corresponding pairs of consecutive interior angles are supplementary.

Determining Congruence of Triangle HL

To determine if triangle HL is congruent, you must first compare the lengths of each side. If the lengths of each side are equal, then the triangles are similar. Next, you must compare the angles of each triangle. If the angles of each triangle are equal, then the triangles are congruent. Finally, you must compare the pairs of vertical angles, alternate interior angles, alternate exterior angles, and consecutive interior angles. If all of these pairs are equal or supplementary, then the triangles are congruent. If all three conditions are met, then it can be concluded that triangle HL is congruent.

Jolly Roger Peanut Butter cost $3. 59 for a small jar last year. This year the jar costs $4. 19. What is the inflation rate, to the nearest tenth percent?

Answers

The inflation rate is 16.71 %

As we know the inflation rate is given by the percentage error.

We know that the formula for the percentage error:

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ] x 100

Let us assume that A represents the inflation rate of percentage error.

Here, the cost of the Jolly Peanut butter is = $ 3.59

So , the original cost = $ 3.59

The increased cost of Jolly Peanut butter is = $ 4.19

So , the new rate = $ 4.19

Now , the inflation rate is given by the formula of percentage error,

Percentage Error = [ ( | Measured Value - True Value | ) / True Value ] x 100

A = [ ( 4.19 - 3.59 ) / 3.59 ] x 100

A =  ( 0.6 / 3.59 ) x 100

A = 0.16713 x 100

A = 16.71 %

Answers

a. The actual distance of the mountain peak from Gavin’s house is 12.2 miles.

b. The actual distance of the mountain peak from Brianna’s house is 12.3 miles.

How to determine the actual distances?

In Mathematics and Geometry, the scale factor of a geometric figure can be calculated by dividing the side lengths of the image by the side lengths of the pre-image:

Scale factor = side length of image (new figure)/side length of pre-image (actual figure).

Scale:

0.245 inch = 1.5 miles

Part a.

0.245/1.5 = New distance/Actual distance

0.25/1.5 = 2/Actual distance

Actual distance = (2 × 1.5)/0.245

Actual distance = 12.2 miles.

Part b.

For the actual distance of the mountain peak from Brianna’s house, we have:

Actual distance = (2.015 × 1.5)/0.245

Actual distance = 12.3 miles.

A ship leaves a port located at point a on a bearing of 030°. It sales a distance of 20 km to point B where it changes direction to a bearing of 75°. Then it sells 25 km to reach a port located at point C.
a) Find the distance between a and C.

B)Find the bearing between point C with respect to a

Answers

a. The distance between points A and C is  37.42 km.

b.  The bearing between point C and point A is found to be 71.48°.

How do we calculate?

a)

Segment 1: From point A to point B:

The ship sails a distance of 20 km on a bearing of 030°,

East displacement = 20 km * cos(30°)

= 20 km * (√3/2)

= 10√3 km

Segment 2: From point B to point C:

The ship sails a distance of 25 km on a bearing of 75°.

East displacement = 25 km * cos(75°)

= 25 km * (√3 + 1)/2

=  21.65 km

The total east displacement from point A to C :

Total east displacement = 10√3 km + 21.65 km

= 31.65 km

Distance between A and C = √(20 km)² + (Total east displacement)²

= √20² + (1.65²

≈ √400² + 1000.4225²

≈ √1400.4225 km²

=  37.42 km

b)

North displacement = (20 km * sin(30°)) + (25 km * sin(75°))

= 20 km * (1/2) + 25 km * (√3/2)

= 10 km + (25√3/2)

= 10 km + 21.65 km

=  31.65 km

Bearing of C with respect to A = arctan(31.65 km / Total east displacement)

= arctan(31.65 km / 10√3 km)

= 71.48°

Answers

Answer:

Step-by-step explanation:

just did edjunity

The root of the given equation x3 + 2x² - 16x - 32 is -2, -4 and 4.

What is root?

Root is defined as a formula or number that, in most cases, represents the answer to an equation. There are some steps which are used to find the root. Divide the supplied number into its prime factors as the first step. Form similar factor pairings in which both factors are equal. This is step two. Take one element from the pair in step three. Calculate the product of the factors you got by taking one from each pair of factors if fourth step.

The equation is as follows: x3 + 2x2 - 16x - 32.

The equation's roots must all be located.

x3 + 2x2 - 16x - 32 = x2(x + 2) after common terms are removed.

- 16 (x + 2)  = (x2 - 16)(x + 2)

We are aware that (a2-b2) = (a-b)(a+b)

So, (x2 - 16) = (x - 4)(x + 4)

x3 + 2x2 - 16x - 32 = (x + 2)(x - 4)(x + 4) is the result now.

To get the roots, use the formulas:

= (x + 2) = 0

x = -2 = (x - 4) = 0

x = 4 = (x + 4) = 0

x = -4

Thus, the root of the given equation x3 + 2x² - 16x - 32 is -2, -4 and 4.

Answers

In this case, the limit is 0, so the series is indeed convergent.

The Root Test is used to determine the convergence or divergence of a series. and it is used the Root Test, we start by finding the nth root of each term in the series.

In this case, the series is

=> [∞] n = 1 4 1 1 n n²,

so we calculate the nth root of each term:

\(= > (1/n^{2} )^{1/n}\)

Then, we take the limit of this expression as n approaches infinity, to find the value of the root.

If this limit is less than 1, the series is convergent. If the limit is greater than or equal to 1, the series is divergent.

In this case, the limit of \((1/n^{2} )^{1/n}\) as n approaches infinity is 0, which is less than 1. This means that the series is convergent.

To confirm this, we can evaluate the limit of the absolute value of each term as n approaches infinity, using the formula

=> lim n → [∞] n |aⁿ|.

If this limit is finite, then the series is convergent.
