Given the function g(x)=x^2+2x-5g(x)=x

dimaraw [331]

We have been given a function $g(x)=x^2+2x-5$ . We are asked to find average rate of change of the function over the interval $-6\leq x\leq 1$ .

We will use average rate of change formula to solve our given problem.

$\text{Average rate of change}=\frac{f(b)-f(a)}{b-a}$

For our given function $b=1$ and $a=-6$ .

$\text{Average rate of change}=\frac{g(1)-g(-6)}{1-(-6)}$

$g(1)=1^2+2(1)-5$

$g(1)=1+2-5$

$g(1)=-2$

$g(-6)=(-6)^2+2(-6)-5$

$g(-6)=36-12-5$

$g(-6)=19$

$\text{Average rate of change}=\frac{-2-19}{1+6}$

$\text{Average rate of change}=\frac{-21}{7}$

$\text{Average rate of change}=-3$

Therefore, the average rate of change of the function is $-3$ over the interval $-6\leq x\leq 1$ .

Question 5(Multiple Choice Worth 7 points)

kotegsom [21]

Answer:

-∞ ; x = 3

Step-by-step explanation:

The graph tends toward -∞ as x approaches 3 from the left. Thus there is a vertical asymptote at x=3, the value of x that makes the denominator zero.

B. {1,2} because they are both whole numbers 0 is not one.

(Proof: Whole Numbers: This set is closed only under addition and multiplication. Integers: This set is closed only under addition, subtraction, and multiplication. Rational Numbers: This set is closed under addition, subtraction, multiplication, and division (with the exception of division by 0)"

In a ∆ABC , angle A + Angle B = 125° and Angle B + Angle C = 150° . Find all the angles of ∆ABC.

mel-nik [20]

$\large\underline{\sf{Solution-}}$

Given that,

<em>In triangle ABC</em>

$\purple{\rm :\longmapsto\:\angle A + \angle B = 125 \degree \: - - - (1) }$

$\purple{\rm :\longmapsto\:\angle B + \angle C = 150 \degree \: - - - (2)}$

We know,

Sum of all interior angles of a triangle is supplementary.

$\purple{\rm :\longmapsto\:\angle A + \angle B + \angle C = 180\degree }$

<u>On adding equation (1) and (2), we get </u>

$\purple{\rm :\longmapsto\:\angle A + \angle B + \angle B + \angle C = 125\degree + 150 \degree \:}$

$\purple{\rm :\longmapsto\:\angle A + \angle B + \angle C + \angle B = 275\degree \:}$

$\purple{\rm :\longmapsto\:180\degree + \angle B = 275\degree \:}$

$\purple{\rm :\longmapsto\:\angle B = 275\degree - 180\degree \:}$

$\purple{\rm :\longmapsto\:\angle B = 95\degree \:}$

On substituting the value in equation (1) and (2), we get

$\purple{\rm :\longmapsto\:\angle A + 95\degree = 125\degree }$

$\purple{\rm :\longmapsto\:\angle A = 125\degree - 95\degree }$

$\purple{\rm :\longmapsto\:\angle A = 30\degree }$

Also, from equation (2), we get

$\purple{\rm :\longmapsto\:95\degree + \angle C = 150\degree }$

$\purple{\rm :\longmapsto\:\angle C = 150\degree - 95\degree }$

$\purple{\rm :\longmapsto\:\angle C = 55\degree }$

Hence,

$\begin{gathered}\begin{gathered}\bf\: \rm\implies \:\begin{cases} &\sf{\angle A = 30\degree } \\ \\ &\sf{\angle B = 95\degree } \\ \\ &\sf{\angle C = 55\degree } \end{cases}\end{gathered}\end{gathered}$
