Answer:

AC=11\frac{\sqrt{3}}{3}\ units  or  AC=6.35\ units

Step-by-step explanation:

we know that

In the right triangle ABC

AC and BC are the legs of the triangle

AB is the hypotenuse

see the attached figure to better understand the problem

tan(30\°)=\frac{AC}{BC}

tan(30\°)=\frac{\sqrt{3}}{3}

so

\frac{\sqrt{3}}{3}=\frac{AC}{BC}

AC=\frac{\sqrt{3}}{3}BC

substitute the value of BC

AC=\frac{\sqrt{3}}{3}(11)

AC=11\frac{\sqrt{3}}{3}\ units

AC=6.35\ units

Answer:

Linear approximation is given by: y = \frac{x}{5}+2

Step-by-step explanation:

We are given the following information in the question:

Number of citations:      5      7.5      10      15       20

 Outputs Residuals:       3       6       10       5          6

We have to find the linear approximation of the data that passes through the points (5, 3) and (20, 6).

Linear approximation is given by:

The equation of line is given by:

(y-y_1) = \displaystyle\frac{y_2-y_2}{x_2-x_1}(x-x_1)

where, (x_1,y_1), (x_2.y_2) is the point through which the line passes.

The equation of line is:

(y-3) = \displaystyle\frac{6-3}{20-5}(x-5)\\\\15(y-3)= 3(x-5)\\15y = 3x-15+45\\15y = 3x + 30\\y = \frac{x}{5}+2

The above equation is the required linear approximation.

What is (2+2+3+10)x(8+9+-9+7)
qwelly [4]

Answer:

<em>255</em>

Step-by-step explanation:

(2+2+3+10) × (8+9+-9+7)

First, remove the brackets:

2 + 2 + 3 + 10 × 8 + 9 + -9 + 7

Now calculate like so:

2 + 2 + 3 + 10 = <em>17</em>

8 + 9 + -9 + 7 = <em>15</em>

<em>(</em><em>17</em><em>)</em><em> </em><em>×</em><em> </em><em>(</em><em>15</em><em>)</em><em> </em><em>=</em><em> </em><em>17</em><em> </em><em>×</em><em> </em><em>15</em><em> </em><em>=</em><em> </em><em>255</em>

<em>PLEASE</em><em> </em><em>DO</em><em> </em><em>MARK</em><em> </em><em>ME</em><em> </em><em>AS</em><em> </em><em>BRAINLIEST UWU</em><em> </em>
