Soccer ball specifications require a diameter of 8.65 inches with an allowable margin of error of 0.05 inch.
Readme [11.4K]

Answer:

Equation for new diameter: |d' - 8.65| ≤ 0.05

Minimum possible diameter = 8.60 inches

Maximum possible diameter = 8.70 inches

Step-by-step explanation:

We are told that:

Ball specifications require a diameter (d) = 8.65 inches.

Allowable margin of error = 0.05 inch

Now, since we have a value for the allowable margin of error, it means that the absolute value equation to determine the possible value or the new diameter (d') would be;

|d' - 8.65| ≤ 0.05

Minimum possible diameter = 8.65 - 0.05 = 8.60 inches

Maximum possible diameter = 8.65 + 0.05 = 8.70 inches

Given: r(x) = x3 - 7, k(x) = 5 ln (2x) Find: (k ○ r) (x)
sergij07 [2.7K]

The value of (k ○ r) (x) from the given parameters in the task content is; 5 ln(2x³ -14)

<h3>What is (k ○ r) (x) from the task content?</h3>

If follows from the task content that;

  • r(x) = x³ - 7 and k(x) = 5 ln (2x)

It therefore follows that;

(k ○ r) (x) = k(r(x)) = 5 ln (2(x³-7)).

On this note, the expression which represents (k ○ r) (x) is; 5 ln(2x³ -14).
