Given :

A right angle triangle ABC .

To Find :

The perimeter of ABC .

Solution :

Since, triangle ABC is right angled and angle ∠ABC is 46° .

So, AC = AB cos 46° = 7.64 units.

Also, CB = AB sin 46° = 7.91 units.

Therefore, the perimeter of ΔABC is :

P = 11 + 7.64 + 7.91 units

P = 26.55 units

Hence, this is the required solution.

Answer: |81-x|<5

Step-by-step explanation:

Given: Temperature of an enclosure for a pet corn snake should be an average of 81° F.

Temperature in the enclosure should not vary by more than 5° F.

Let x= Temperature in the enclosure

Then, difference between average and current temperature should less the 5.

i.e. |81-x|<5 (required absolute value equation )

hence, the absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure:

|81-x|<5

Help find the value of x

Nookie1986 [14]

Answer:

x = 82

Step-by-step explanation:

The bottom angle is the same as the angle next to x + 6

A straight angle is 180 degrees.

You add the given angles: (x + 6) + (x + 10) = 2x + 16

180 = 2x + 16

- 16 -16

164 = 2x

x = 82

Calculate the average rate of change of f(x) = 1 x - x2 - 2 for 3 ≤ x ≤ 6. A) -163 18 B) -18 163 C) 163 18 D) 18 163

To solve this we are going to use the average rate of change formula: $A(x)= \frac{f(b)-f(a)}{b-a}$
where
$A(x)$ is the average rate of change of the function
$f(a)$ is the position function evaluated at $a$
$f(b)$ is the position function evaluated at $b$
$a$ is the first point in the interval
$b$ is the second point in the interval

We can infer for our problem that the first point is 3 and the second point is 6, so $a=3$ and $b=6$ . Lets replace those values in our formula:
$A(x)= \frac{f(b)-f(a)}{b-a}$
$A(x)= \frac{f(6)-f(3)}{6-3}$
$A(x)= \frac{6-6^2-2-(3-3^2-2)}{3}$
$A(x)= \frac{-32-(-8)}{3}$
$A(x)= \frac{-32+8}{3}$
$A(x)= \frac{-24}{3}$
$A(x)=-8$

We can conclude that the average rate of change of the function f(x) = 1 x - x2 - 2 for <span>3 ≤ x ≤ 6 is -8</span>
