ABRound Your Answer To The Nearest Hundredth.4A25?B

Answers

Answer 1

Answer:

AB ≈ 4.41

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos25° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{4}{AB}[/tex] ( multiply both sides by AB )

AB × cos25° = 4 ( divide both sides by cos25° )

AB = [tex]\frac{4}{cos25}[/tex] ≈ 4.41 ( to the nearest hundredth )

Answer:

  (c) 5.4°

Step-by-step explanation:

We can simply determine the difference between the angles of the vectors:

  arctan(8/-5) -arctan(8/-4) = 122.005° -116.565° = 5.440°

The angle between the vectors is about 5.4°.

__

Alternate solutions

1) We could also determine the angle of their ratio.

  u/v = (-5 +8i)/(-4 +8i) = (-5 +8i)(-4 -8i)/(4² +8²) = (84 +8i)/80 = 1.05 +0.1i

  angle = arctan(0.1/1.05) = 5.440°

__

2) Tan(a-b) = (tan(a)+tan(b))/(1 -tan(a)(tan(b))

  tan(∠u -∠v) = ((tan(∠u) -tan(∠v))/(1 +tan(∠u)tan(∠v))

  = (-1.6 -(-2))/(1 +(-1.6)(-2)) = 0.4/4.2

  ∠u -∠v = arctan(2/21) = 5.440°

If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?

Answers

Answer:

Yes

Step-by-step explanation:

The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

What is a quadrilateral?

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.

If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Answers

Answer:

1/7

Step-by-step explanation:

Given that :

Line AB contains points A (8, −4) and B (1, −5)

Slope = Rise / Run

Rise = y2 - y1 = - 5 - (-4) = - 5 + 4 = - 1

Run = x2 - x1 = 1 - 8 = - 7

Slope = Rise / Run = - 1 / - 7

Slope = 1/7

Harpo, Groucho, Chico, Zeppo, Gummo, Karl, and Skid have won three tickets to the opera. They will randomly choose three people from their group to attend the opera. How many outcomes are possible?

Answers

Answer:

35

Step-by-step explanation:

This is a combination problem therefore we need to use the combination formula using factorials, plug in the values for n and r which would be 7 since there are 7 individuals in the group and 3 because we are making outcomes of 3.

C(n,r)=C(7,3)

=7!(3!(7−3)!)

=7!3!×4!

= 35

Finally, we can see that the total number of possible outcomes is 35

Complete the equation of the line through (-6, 5) and (-3, -3)

Answers

Answer:

y = -8/3x - 11

Step-by-step explanation:

(-6, 5) and (-3, -3)

Slope:

m=(y2-y1)/(x2-x1)

m=(-3-5)/(-3+6)

m=(-8)/3

m= -8/3

Slope-intercept:

y - y1 = m(x - x1)

y - 5 = -8/3(x + 6)

y - 5 = -8/3x - 16

y = -8/3x - 11

Do not ask. They need you to write a method that will determine whether it will be successfull (returns true) or not (returns false).

The rules for making that determination are detailed below. Variables declarations & initialization: Boolean variable named "result", initialized to false. Steps for the code: First, if less than 1 squirrel attends, then "result" is assigned false. Else, we consider the following conditions: If we have less than, or exactly, 10 squirrels attending: Then: If we have less than 15 walnuts, Then: "result" is set to false. Else: if we have less than, or exactly, 30 walnuts Then: "result" is set to true. Else: "result" is set to false.
