The height of a tree in feet over x years is modeled by the function f(x).

Evgesh-ka [11]

If e-the initial hight of the tree, and the function imply some brackets like

f(x)=30/(1+29e-0.5x) then

for every

$0.5x > 29e + 1$

the rate of growth is negative, the maximum growth per unit of time would be 30ft

$x \geqslant 1$

then

$29e < - 0.5$

so the tree couldn't be 2ft tall initially

if the brackets are something like

f(x)=30:(1+29e)-0.5x then the results may differ

What is the Inequality for this graph?

mote1985 [20]

Given:

The graph of an inequality.

To find:

The inequality for the given graph.

Solution:

From the given graph it is clear that the boundary line passes through the points (6,0) and (0,-4). So, the equation of the line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

$y-0=\dfrac{-4-0}{0-6}(x-6)$

$y=\dfrac{-4}{-6}(x-6)$

$y=\dfrac{2}{3}(x-6)$

$y=\dfrac{2}{3}x-4$

The area under the boundary line is shaded and boundary line is a dotted line it means the points on the line are not included in the solution set. So, the inequality sing must be <.

$y$

Therefore, the required inequality for the given graph is $y$ .

Determine the number of cement blocks needed to put up a wall measuring 20 meters in length and 1.5 meters in height. Each block

Montano1993 [528]

calculate area of wall

20 x 1.5 = 30 square meters

now calculate area of 1 block

12 x 18 =216 square centimeters

convert cm to meters 1 cm^2 = 0.0001m^2

so 216 x 0.0001 = 0.0216 sq meter for 1 block

divide area of wall by area of block

30/0.0216 = 1388.88 so 1389 blocks are required.

If m∠5 = 115 degrees, find m∠1 =

lana66690 [7]

$▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪$

Question 1. If m∠5 = 115 degrees, find m∠1 = 115°

because they form corresponding Angle pair

Question 2. If m∠7 = 30 degrees, find m∠2 = 30°

because they form Alternate Exterior angle pair

Question 3. If m∠6 = 50 degrees, find m∠4 = 50°

because they form Alternate Interior Angle pair

Question 4. If m∠4 = 72 degrees, find m∠1 = 108°

because they form linear pair, their sum = 180°

Angle 4 + Angle 1 =180°

Angle 1 = 180° - Angle 4

Angle 1 = 180° - 72°

Angle 1 = 108°
