A dolphin swims 665,280 feet in 3 hours find the dolphin's rate in feet per hour.

Answer: 36

Step-by-step explanation:

[tex]\overline{AB} \cong \overline{BC}[/tex] (Triangle ABC is isosceles)

[tex]m\angle CAB=m\angle CBA=30^{\circ}[/tex] (base angles of an isosceles triangle are congruent)

[tex]\angle MCB=90^{\circ}[/tex] (In triangle CMB, angles in a triangle add to 180 degrees)

[tex]\angle ACM=30^{\circ}[/tex] (triangle sum theorem)

[tex]MB=24[/tex] (30-60-90 triangle CMB)

[tex]AB=12[/tex] (sides opposite congruent angles in a triangle are congruent)

[tex]AB=36[/tex] (segment addition postulate)

The value of AB = 36

An isosceles triangle is a triangle with base angles equal with any two sides equal.

Analysis:

∠ACB = 120

ABC is isosceles, so ∠CAB = ∠CBA = x

x + x + 120 = 180 ( sum of angles in Δ ABC)

2x = 60

x = 30

∠AMC = 180 - ∠BMC( angles on a straight line)

           = 180 - 60 = 120

∠ACM = 180 - (30 + 120) = 180 - 150 = 30°

∠MCB = 90°

using sine rule,

12/sin 30 = AM/ sin 30

AM = 12

MB/sin 90 = 12/sin30

MB sin 30 = 12 sin 90

MB = 12/sin 30 = 12/0.5 = 24

AB = MB + AM = 24 + 12 = 36

Answer:

horizontal asymptote of y = -7

Step-by-step explanation:

The parent function is shown on the coordinate plane. The graph of the parent function has a horizontal asymptote (an imaginary line that the graph approaches, but never touches or intersects) of y = 0.

Since the function of g(x) = e^x - 7 is the graph of the parent function translated 7 units down, the function would have a horizontal asymptote of y = -7.

ABC is a right angle

ABCD is a parallelogram

Opposite sides of a parallelogram are equal

So

Opposite angles are equal

<B=<D

Hence

∆ABC and ∆CDB are congruent by SAS

Answer:

x = 108°

y = 72°

z = 36°

Step-by-step explanation:

   If all sides are equal in a pentagon, then it is a regular pentagon.

n = the number of sides = 5

Sum of all angles in a pentagon = (n -2) * 180

                                                     = (5 - 2)* 180

                                                     = 3 *180

                                                     = 540°

Sum of each angle of regular pentagon = 540 ÷ 5

                                                                  = 108°

  [tex]\sf \boxed{\bf x= 108^\circ}[/tex]

Linear pair: If the non common arm of adjacent angles form a straight line, then the adjacent angles are called linear pair and they add up to 180°

∠DCB + y = 180 °   {Linear pair}

  108  + y = 180

            y = 180 - 108

            [tex]\sf \boxed{\bf y = 72^\circ}[/tex]

Exterior angle property of triangle: The exterior angle equals the sum of opposite interior angles.

In Δ BCF ,

  x = y + z

Now, substitute the values of x and y , and we can find the value of z.

      108° = 72 + z

108  - 72 = z

     [tex]\sf \boxed{\bf z = 36^\circ}[/tex]

Step-by-step explanation:

h² means h * h

We can start with a number like "10". 10*10 = 100, so we have to guess a bit higher.

12*12 = 144.

However, it can also be -12 * -12 since the two negative signs will cancel each other out.

So, h can be 12 or -12

Answer: +12 or -12

Step-by-step explanation:

h^2=144

taking sqrt root on both sides

h=±12

so answer is +12 or-12

so when you want to rationalize the denominator when it's in the form [tex](a-\sqrt{b})[/tex] you multiply by the conjugate which is [tex](a+\sqrt{b})[/tex] which is where the sign is the opposite. This is because it's using the difference of squares to get rid of the square root. Because [tex](a-b)(a+b) = a^2-b^2[/tex] this will remove the square root since it's going to become square and the ab - ab will cancel so there will be no square root

Answer:

A(5 ; 8)

Step-by-step explanation:

y = 5x - 17

y = x + 3

    5x - 17 = x + 3

⇔ 5x - x = 3 + 17

⇔ 4x = 20

⇔ x = 20/4

⇔ x = 5

y = 5 + 3 = 8

So (5 ; 8)

Answer:

We can use the substitution method to solve the system of equations.

Since y = x + 3, we can substitute this expression for y in the first equation:

y = 5x - 17

x + 3 = 5x - 17

Subtracting x from both sides, we get:

3 = 4x - 17

Adding 17 to both sides, we get:

20 = 4x

Dividing both sides by 4, we get:

x = 5

Substituting this value of x into either equation, we get:

y = x + 3 = 5 + 3 = 8

Therefore, the correct ordered pair is (5, 8), which corresponds to the point where the two lines intersect.

The correct answer is (A) (5,8).
