F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a

f(x) = (5x+1) / x g(x) = x / (5x+1)

f(1) = 6, but g(6) = 6/31 ≠ 1

So, f(x) and g(x) are NOT inverse functions.

No he did not spend 110% more time doing homework if he did it would be 12hrs to find this put 11 in its decimal form and multiply it by 110 =12.1

What is the area of OA to the nearest<br> tenth? (Use 3.14 for T.)

lana66690 [7]

Answer:

50.2 m²

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius , here r = 4 ), thus

A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )

The height of a triangle is 4 inches greater than twice its base. The area of the triangle is no more than 168 in.² which inequa

Gennadij [26K]

<h2>Answer:</h2>

Correct option: B

<h2>Step-by-step explanation:</h2>

When we say a is no more than b, we express this in a mathematical language as follows:

$a\leq b$

In this inequality, we know that the area of the triangle is no more than 168 in². In other words, if the area is named $A$ , then:

$\mathbf{(1)} \ A\leq 168$

We also know that the height of a triangle is 4 inches greater than twice its base. Translating this in a mathematical language:

$\mathbf{(2)} \ h=2b+4 \\ \\ h:height \ of \ the \ triangle \\ \\ b:base \ of \ the \ triangle$

From geometry, we know that the area of a triangle is given by:

$\mathbf{(3)} \ A=\frac{bh}{2}$

Matching (1), (2) and (3):

$\frac{bh}{2}\leq 168$

Since the length of the base of the triangle is $x$ , then $b=x$

$\frac{x(2x+4)}{2}\leq 168 \\ \\ Common \ factor \ 2: \\ \\ \frac{2x(x+2)}{2}\leq 168 \\ \\ \boxed{x(x+2)\leq 168}$

Finally, correct option is B.
