Since DB is the median of the triangle, it would bisect the base AC. This would mean that AB and BC are equal halves of the whole AC. So, if AC is 50, then,

AC = AB + BC
since AB = BC,
AC = 2AB
50 = 2AB
AB = 50/2
AB = 25

The answer is 25.

<u>Answer-</u>

<em>The length of AB is </em><em>25 units.</em>

<u>Solution-</u>

Median-

A median of a triangle is a line segment joining a vertex to the midpoint of the opposing side, bisecting it.

As given that, DB is a median of the triangle. DB is a median to side AC, so it bisects or divides AC in two equal parts.

Hence,

\Rightarrow AC=2\times AB

\Rightarrow AB=\dfrac{1}{2}AC

\Rightarrow AB=\dfrac{1}{2}\times 50 = 25

Therefore, the length of AB is 25 units.

Which statement best explains the relationship between
Nataly [62]

Answer:

The best statement which explains the relationship between lines AB and CD is "They are parallel because their slopes are equal" ⇒ A

Step-by-step explanation:

  • Parallel lines have equal slopes and different y-intercepts
  • The rule of the slope of a line passes through points (x1, y1) and (x2, y2) is m = \frac{y2-y1}{x2-x1}

In the given figure

∵ The blue line passes through points A and B

∵ A = (-4, -2) and B = (4, 4)

∴ x1 = -4 and y1 = -2

∴ x2 = 4 and y2 = 4

→ Substitute them in the rule of the slope

∵ m(AB) = \frac{4--2}{4--4} = \frac{4+2}{4+4} = \frac{6}{8} = \frac{3}{4}

∴ The slope of line AB is  \frac{3}{4}

∵ The green line passes through points C and D

∵ C = (0, -3) and D = (4, 0)

∴ x1 = 0 and y1 = -3

∴ x2 = 4 and y2 = 0

→ Substitute them in the rule of the slope

∵ m(CD) = \frac{0--3}{4-0} = \frac{0+3}{4} = \frac{3}{4}

∴ The slope of line CD is  \frac{3}{4}

∵ The slope of line AB = the slope of line CD

∵ Parallel lines have the same slope

∴ AB // CD

∴ AB and CD are parallel lines

The best statement which explains the relationship between lines AB and CD is "They are parallel because their slopes are equal"

A) The linear model represents the height, f(x), of a water balloon thrown off the roof of a building over times, x measured in
Brums [2.3K]

From the given linear function, we have that:

A. The function is constant on the following interval: B.2 ≤ x ≤ 5.

B. The function is increasing on the following interval: A.0 ≤ x ≤ 2.

C. The function is decreasing the fastest on the following interval: D.5 ≤ x ≤ 6.

D. The justification for the previous item is: D.5 ≤ x ≤ 6 is the interval where the slope is the steepest.

<h3>When a function is constant?</h3>

A function is constant when it's graph is an horizontal line, hence in this problem the function is constant for two intervals.

  • 2 ≤ x ≤ 5.
  • 10 ≤ x ≤ ∞.

Hence, in item A, option B is correct.

<h3>When a function is increasing?</h3>

A function is increasing on the intervals that y is increasing while x increases, that is, the function is moving right and up.

Hence, in item B, option A is correct.

<h3>When a function is decreasing?</h3>

A function is decreasing on the intervals that y is decreasing while x increases, that is, the function is moving right and down.

The decrease is faster when the division of the change in the output by the change in the input has the lower value(greater absolute negative).

Hence:

  • In item 3, option D is correct.
  • In item 4, option D is correct.

Find the lateral area of this cone.
tatyana61 [14]

Given:

Radius of the base of the cone = 12 in.

The slant height of the cone = 15 in.

To find:

The lateral surface area of the given cone.

Solution:

The lateral surface area of the cone is:

LA=\pi rl

Where, r is the radius of the base of the cone and h is the slant height of the cone.

Putting r=12,h=15, we get

LA=\pi (12)(15)

LA=180\pi

The lateral surface area of the cone is 180π in ² and the missing value for the blank is 180.
