Answer:

k = - [tex]\frac{16}{15}[/tex]

Step-by-step explanation:

Since x = - 2 is a zero , then p(- 2) = 0 , that is

2(- 2)² - 3(- 2)(5k + 4) = 0

2(4) + 6(5k + 4) = 0 ← distribute parenthesis

8 + 30k + 24 = 0

30k + 32 = 0 ( subtract 32 from both sides )

30k = - 32 ( divide both sides by 30 )

k = [tex]\frac{-32}{30}[/tex] = - [tex]\frac{16}{15}[/tex]

Given Polynomial P(x) = 2x^2-3x(5k+4)

Zero = -2

We know that

If -2 is zero of the Polynomial then it satisfies the given Polynomial

⇛P(-2) = 0

⇛ 2(-2)^2-3(-2)(5k+4)=0

⇛ 2(4)+6(5k+4) = 0

⇛ 8+30k+24 = 0

⇛ 30k+32 = 0

⇛ 30 k = -32

⇛ k = -32/30

⇛ k = -16/15

Answer:- The value of k = -16/15.

Answer:

3.7 mi/day

Step-by-step explanation:

Subtracting 16 mi from 27.1 mi yields 11.1 mi to be covered in 3 additional  days.  The unit rate (number of miles per day) necessary for Jace to have ridden 27.1 miles total is 11.1 mi / 3 days = 3.7 mi/day

Riding 3.7 mi/day on each of the remaining 3 days would bring Jace's total miles up to 27.1 mi.

Answer:

y = -2x

Step-by-step explanation:

Slope = (change in y-values)/(change in x-values)

Slope = (0 - 4)/(0 - (-2)

Slope = -4/2

Slope = -2

Use the slope = -2 and point (0, 0) and substitute into y= mx + b to solve for b

y = mx + b

0 = -2(0) +b

0 = b

Answer:

The answer is D

Step-by-step explanation:

A cant be right because the graph isn't a straight line.

B cant be right because from 0 to 60 the graph the line goes at a(n) upward slope not a straight line.

Although the first part of question c is right, the second part is wrong. From 50-90 the ling goes at a downward slope via decreasing, which isn't equal like it said so question C is wrong.

So the correct answer is D

Answer:

  44.5 km on a bearing of 134.1°

Step-by-step explanation:

A suitable vector calculator will tell you the location of the ship from port is ...

  21∠32° +45∠287° = 44.5∠-45.9°

The bearing of the port is in the reverse direction, so 180° added to this:

  180° +(-45.9°) = 134.1°

The distance from port is 44.5 km. The bearing of the port is 134.1°.

_____

Additional comment

The distance from port is perhaps most easily found using the Law of Cosines. It is the third side of a triangle with sides 21 and 45. The included angle is (287° -(180° +32°)) = 75°. The distance is then ...

  c = √(a² +b² -2ab·cos(C)) = √(21² +45² -2·21·45·cos(75°)) ≈ √1976.83

  ≈ 44.5 km

The angle between the 32° bearing and the bearing from the port to the ship can be found using the Law of Sines.

  B = arcsin(b/c·sin(C)) = arcsin(45/44.5sin(75°)) ≈ 77.9°

so, the bearing angle from the ship to the port is ...

  180° +(32° -77.9°) = 134.1°

Answer:

The home team

Step-by-step explanation:

1 touchdown is equal to 6 points (plus a extra point for the kick)

1 field goal is worth 3 points

If you are including the extra point as the touchdown it would be 7 pts times 3 touchdowns which would put the first team at 21 points total (if not including the extra point they would have 18 points)

For the 2nd team the have 3pts times 4 field goals which would put the visiting team at 12 points total.

The home team scored more points at 21 points versus the visiting team which had only scored 12 points.

Answer:

Part A (Equation): C(g) = 0.99g + 12.49

Part B: Total cost of 6 games = $18.43

Step-by-step explanation:

Given the $0.99 charge to download a game, and a membership fee of $12.49:

A cost function (or equation) that represents the total cost (C ), in dollars, to download g number of games is:  

C(g) = 0.99g + 12.49

where:

To find the cost of downloading 6 games C(6), substitute the value of g = 6 into the equation:

C(g) = 0.99g + 12.49

C(6) = 0.99(6) + 12.49

C(6) = 5.94 + 12.49

C(6) = 18.43

Therefore, it costs $18.43 to download 6 games.

x ≈ 3.2

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{3.7}[/tex] ( multiply both sides by 3.7 )

3.7 × cos29° = x , then

x ≈ 3.2 ( to the nearest tenth )

Answer:

3.2

Step-by-step explanation:

we have two angles, 29 and 90.

we need one more angle to make the total sum of the angles 180.

the angle to do this is 61.

the area of this triangle so far is 2.90244.

using the area, we can find that the x side is 3.23609.

round 3.23609 to the tenth, we get 3.2

Answer:

The requirements for taking out a loan tend to be very strict, and therefore, an impressive internship program would not be something that can meet the requirements to obtain a loan of $6500.

Step-by-step explanation:

1. If you were trying to decide whether to take out an auto loan for $6500 to buy your first car, thereby allowing you to commute for an impressive summer internship program next year, that loan would not meet the requirements.

Is it necessary?

No, travelling can be done by other means.

Do the monthly payments fit in your budget?

Maybe

Could you save instead of borrow?

Yes saving for the whole year is better than borrow.

Is it worth the added interest?

No, its not worth the added interest.

All of the answers indicate that the loan does not meet the requirements.

Paying a huge amount of interest for something which is not that necessary is useless.

Answer:

  AED 2 for 3 eggs

Step-by-step explanation:

Price (p) is proportional to the number of eggs:

  p/3 = 8/12

  p = 3(8/12) = 8(3/12) = 8/4 = 2

The cost of 1/4 as many eggs will be 1/4 as much: AED 2 for 3 eggs.
