Answer:

$a_3=22$

Step-by-step explanation:

Given that,

a₁ = 10

$a_n=a_{n-1}+6$

We can find second term first.

$a_2=a_{2-1}+6\\\\=a_1+6\\\\=10+6\ (Given\ a_1=10)\\\\=16$

We need to find the third term of the above sequence. Put n = 3 in the above sequence as follows :

$a_3=a_{3-1}+6\\\\=a_2+6$

Put a₂ = 16

$a_3=16+6\\\\=22$

Hence, the third term of the sequence is 22.

To determine the inverse of function f,

lisabon 2012 [21]

Answer:

To determine the inverse of function f, change f(x) to y, switch x and y, and solve for y.

$\frac{1}{8} (x-4)^3$

Step-by-step explanation:

f(x) = $\sqrt[3]{8x} +4$

Change f(x) to y: y = $\sqrt[3]{8x} +4$

Switch x and y: x = $\sqrt[3]{8y} +4$

Solving for y: x - 4 = $\sqrt[3]{8y}$

(x-4)^3 = 8y

y = $\frac{1}{8}$ $(x-4)^3$

Therefore: inverse of function f = $\frac{1}{8} (x-4)^3$

I built a storage shed in the shape of a rectangular box on a square base. The material that I used for the base cost $4 per squ

Dmitrij [34]

Answer:

$V = \frac{450L - 6 L^{3} }{10}$

Step-by-step explanation:

The volume of a cuboid can be determined simply by the formula: V= LWH

(where: L is length, H is height and W is width).

In this particular case the base is a square, which means the length and width are equal. Hence we can modify the equation of volume:

$V = L^{2} H$

Now we need to find the value of H in terms of L. For this we can develop the equation for cost incurred in building the storage shed. We find the area of each side of the cuboid, and then we multiply it by cost per square feet to find the total cost incurred; as shown below:

Area:

Base: $L$ × $L = L^{2}$
