Find the average rate of change between f(-7) and f(-1) in the function f(x)=x^2+2x -8

Mathematics

Viktor [21]3 years ago
3 0

Solve the equation by replacing x with -7 and then -1.

Then subtract the two to find the difference and divide that by the difference between -7 and -1.

f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27

f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9

Difference between 27 and -9 = -36

Difference between -1 and -7 = -6

Rate of change = -36 /-6 = 6

Suppose m∠ABH>m∠GHB in the figure below. What is an inequality that relates AH and GB?
kvv77 [185]

Given that m∠ABH > m∠GHB, the inequality that relates AH and GB based on the <em>relationship between the angles and sides</em> of a triangle is: AH > BG.

<em><u>Recall:</u></em>

  • The relationship between the <em>sides and angles</em> of a triangle is such that the size of an angle is <em>relative </em>to the length of the side it is directly opposite to.
  • This means, the biggest angle measure will be opposite to the longest side, and vice versa in the triangle.

<em>Given the image attached below where,</em>

m∠ABH > m∠GHB

∠ABH is directly opposite side AH

∠GHB is directly opposite to side GB

  • Since m∠ABH > m∠GHB, the inequality that relates AH and GB based on the <em>relationship between the angles and sides</em> of a triangle is: AH > BG.

Find the sum <br>6+9+12+...+93<br><br>Sn=
Burka [1]
We notice that:
9-6 = 3
12-9 = 3 , Then we can conclude that this is an arithmetic progression with:
1st term a₁ = 6 and with common difference d = 3

So the first term is 6 and the last term is 93.
the formula of the sum in a A.P is :

S = (a + last term).n/2, n being the rank of the last term. So to be
able to find S, we have to calculate the value of n

We know that the last value of a A.P is :
last value = a₁ + (n-1)d
93 = 6 +(n-1)(3) → 93 = 6 + 3n -3 → n = 90/3 → n = 30 (rank 30th)

Now we can find the sum:
S = (a₁ + last term)n/2

S = (6+93)30/2

S = (99).15 = 1,485
