HELP! Use the ratio test to determine whether the series is convergent or divergent.

Answer:

D)  9:20 am

Step-by-step explanation:

Train A's route = 20 mins

Train B's route = 80 mins

80 ÷ 20 = 4

Therefore, Train B's route is 4 times the length of Train A's route.

Therefore, the time Train A and B will leave the station at the same time will be the first time Train B leaves after 8am.

1 hour = 60 minutes

8am + 80 minutes = 8am + 1 hr + 20 minutes = 9:20 am

Answer:

  2(3x -1)(2x +3) = 0

Step-by-step explanation:

A graphing calculator can often provide useful help in discovering the real factors of polynomials.

We presume you want to factor the standard form equation ...

  12x^2 +14x -6 = 0 . . . . . subtract 18 from both sides

  2(6x^2 +7x -3) = 0 . . . . factor out the common factor

  2(6x^2 +9x -2x -3) = 0 . . . . split the middle term to aid factoring

  2(3x(2x +3) -1(2x +3)) = 0 . . . . factor pairs of terms

  2(3x -1)(2x +3) = 0 . . . . . factored standard form equation

_____

Additional comments

The calculator graph shows the zeros are rational and have values -3/2 and 1/3. A zero of x=p means (x -p) is a factor. Translated to factors without fractions, these would be ...

  (x +3/2) ⇒ (2x +3)   and   (x -1/3) ⇒ (3x -1)

The only remaining job is to find the additional factor that makes the leading coefficient be 12 instead of (2)(3) = 6.

__

When factoring 6x^2 +7x -3, we're looking for two numbers that have a sum of +7 and a product of (6)(-3) = -18. The factors we need are 9 and -2, which are the values we use when we split the middle term: 7x ⇒ 9x -2x.

We choose to do the factoring this way because it is straightforward and relatively easy to explain. There are other methods used when the leading coefficient is not 1, but they can be more difficult to explain.

Answer:

A. The solution to a system of equations is when the values of x are the same for both equations and if the y-values also match. With this being said, if x and y are the same in both equations, then that is the solution of the system of equations. We can use the table to find when x and y are equal in both equations to find the solution

Answer:

0.78

Step-by-step explanation:

To know which one is the greatest, convert all of them into decimals.

3/4 is the same as 0.75

50% is the same as 0.50

0.78 doesn't needs to be changed

We now have 0.75, 0.50 and 0.78.

Out of all these numbers, 0.78 is the greatest number.

5) Ally is buying a speed boat for $10,000 with a down payment of $2,500. The bank approved a simple interest flat rate loan for 5 years at 7% APR. How much are the monthly loan payments? (round to the nearest cent)

Answer: B) $168.75

The monthly loan payments should be [tex]\$168.75[/tex].

Option B is correct.

Given that, Ally is buying a speed boat for $10,000 with a down payment of $2,500.

Remaining amount Ally have to pay,

                                      [tex]=10000-2500=7500[/tex]

Rate of interest [tex]r=7\%[/tex] , time [tex]t=5[/tex] years and Principal [tex]P=7500[/tex]

          Simple interest,  [tex]S.I=\frac{P*r*t}{100}[/tex]

                          [tex]S.I=\frac{7500*7*5}{100} \\\\S.I=2625[/tex]

In 5 years, Ally have to pay,

                                 [tex]=7500+2625=10125[/tex]

In one month, Ally have to pay [tex]=\frac{10125}{60}=\$168.75[/tex]

We can identify the sides of a right triangle by describing their location in relation to a given angle.

There are three basic trigonometric ratios:

We use theta (θ) to represent an angle.

We are asked to find [tex]\cos(\beta)[/tex] in the triangle.

[tex]\cos\theta=\dfrac{adjacent}{hypotenuse}[/tex]

The side adjacent to β measures 8 units.

The hypotenuse of the right triangle measures 17 units.

[tex]\cos\beta=\dfrac{8}{17}[/tex]

Therefore, [tex]\cos\beta=\dfrac{8}{17}[/tex].

No, because a scalene triangle has to have all sides that are different lengths. 2 sides being 13 inches would mean that the triangle has 2 sides that are equal, making it an isosceles triangle.

Answer:

  no

Step-by-step explanation:

A triangle is scalene when its sides have three different lengths. Your triangle has two sides with the same measure, so it is isosceles, not scalene.

Answer:

x=35

Step-by-step explanation:

180-147=33 (angles in a straight line)

33+3x+42=180 (angles in a triangle)

3x+42=147

147-42=105

105/3=35

Answer: Shown below

Step-by-step explanation:

Since it's a square, we will refer to its values as x. Using that, we can make an equation for the rectangle.
(x + 15) * ( x - 13) = 60

We can expand it and simplify so that we get a zero on one side and a polynomial on the other.

(x + 15)(x - 13) - 60 = 0

x² + 2x - 225 = 0

We simplify the binomial so we get two answers for x.

(x - 15)(x + 17) = 0

x = 15 and -17

Now we have two answers. So which one is right? Well, the sides cannot be negative, therefore we must use 15 and not -17.

15² = 225

Our answer is 225
