Answer:

Step-by-step explanation:

bisection mean cutting angles in half, making the angle cut in half congruent

m<ABD = m<CBD

3x + 6 = 7x - 18 (substitution)

24 = 4x (subtraction and addition)

x = 6 (division)

m<ABD = 18 + 6 = 24

m<CBD = 42 - 18 = 24

m<ABC = 24 + 24 = 48

Answer:

m∠ABD° = 24°

m∠CBD°  = 24°

m∠ABC°  = 48°

Step-by-step explanation:

Since [tex]\sf{\overrightarrow{BD}}[/tex] bisects ∠ABC, then it means that ∠ABD + ∠CBD = ∠ABC.

Hence, we can establish the following equality statement:

m∠ABD° = m∠CBD°

Substitute the values for both angles and solve for the value of x:

m∠ABD° = m∠CBD°

3x + 6 = 7x - 18

Subtract 3x from both sides:

3x - 3x + 6 = 7x - 3x - 18

6 = 4x - 18

Add 18 to both sides:

6 + 18 = 4x - 18 + 18

24 = 4x

Divide both sides by 4 to solve for x:

[tex]\large\mathsf{\frac{24}{4}\:=\:\frac{4x}{4}}[/tex]

x = 6

Substitute the value of x = 6 to find the measure of the following angles:

m∠ABD° = 3x + 6 = 3(6) + 6 = 24°

m∠CBD°  = 7x - 18 = 7(6) - 18 = 24°

m∠ABC°  = m∠ABD° + m∠CBD° = 48°

Answer:

3rd option

Step-by-step explanation:

A translation of 5 units up , in the positive y- direction means add 5 to the y- coordinate.

A translation of 3 units left, in the negative x- direction means subtract 3 from the x- coordinate.

Then translation rule is

(x, y ) → (x - 3, y + 5 )

Answer:

[tex]A=10cm^{2}[/tex]

Step-by-step explanation:

The formula to find the area of a trapezoid is,

Area = [tex]\frac{1}{2} *(a +b)*height[/tex]

(a+b) ⇒ Sum of the parallel sides

Let us solve now.

[tex]A =\frac{1}{2} *(a +b)*height[/tex]

[tex]A=\frac{1}{2} *(1\frac{1}{2} +3\frac{1}{2} )*4[/tex]

[tex]A=\frac{1}{2} *(\frac{3}{2} +\frac{7}{2} )*4[/tex]

[tex]A=\frac{1}{2} *(\frac{10}{2} )*4[/tex]

[tex]A=\frac{1}{2} *(5 )*4[/tex]

[tex]A=\frac{1}{2} *20[/tex]

[tex]A=10cm^{2}[/tex]

The average speed is 70 miles per hour and the instantaneous speed is 68

miles per hour.

The average speed is the total distance travelled divided by the elapsed time

while the instantaneous speed is the accurate speed covered by the object

at a given instant of time.

Mathematically,

average speed = total distance travelled by the object / total time taken by

the object

Instantaneous speed = distance of an instant / time of an instant.

Therefore,

The average speed is 70 miles per hour.

The instantaneous speed is 68 miles per hour.

Answer:

Length of GB = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

Length of GB = Length of GD

               [tex]\frac{1}{2}[/tex]x+1 = [tex]\frac{2x-3}{2}[/tex]

           2([tex]\frac{1}{2}[/tex]x+1) = 2([tex]\frac{2x-3}{2}[/tex])

Answer:

Step-by-step explanation:

We have to assume you intend everything to the right of the slash (/) to be denominator. Ordinarily, only the first factor would be considered denominator according to the Order of Operations.

ab/cd = (ab/c)d . . . according to the order of operations.

__

The degree of the numerator or denominator is essentially the number of factors involving x.

1. The numerator has 3 factors, hence degree 3. The denominator has 2 factors, hence degree 2. The degree of the numerator is 1 more than the degree of the denominator, so the function will have a slant asymptote.

  degrees: num/den = 3/2

__

2. The numerator has 2 factors, hence degree 2. The denominator has one binomial factor and 3 factors of x, hence degree 4. The degree of the denominator is higher than the degree of the numerator, so the function will have y = 0 as its horizontal asymptote.

  degrees: num/den = 2/4 --- y = 0 horizontal asymptote

__

3. The numerator has 2 factors, as does the denominator. Hence the degree of each is 2. The horizontal asymptote will be a constant equal to the ratio of the leading coefficients: y = 5/3.

  degrees: num/den = 2/2

Answer:

  (c)  20 feet

Step-by-step explanation:

At the water's surface, y=0. We want to find the values of x for that case.

  x^2 -20x -0 = 0

  x(x -20) = 0 . . . . . . factor

This has solutions x=0 and x=20. The difference between them is ...

  20 - 0 = 20

The dolphin is 20 ft from its starting point on the water's surface.

The dolphin will travel 20 feet from its starting point along the water's surface option third is correct.

It is defined as the graph of a quadratic function that has something bowl-shaped.

The dolphin dives down into the ocean and resurfaces along a path that is:

x² – 20x – 4y = 0

The dolphin path will be a downside parabola.

The starting point will be (0, 0) and the endpoint will be (20, 0)

The distance between these points:

[tex]\rm d=\sqrt{(0-0)^2+(20-0)^2}[/tex]

d = 20 feet

Thus, the dolphin will travel 20 feet from its starting point along the water's surface option third is correct.
