Answer:

$a_{n}$ = 4n + 3

Step-by-step explanation:

Note there is a common difference d between consecutive terms, that is

d = 11 - 7 = 15 - 11 = 19 - 15 = 4

This indicates the sequence is arithmetic with n th term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 4, thus

$a_{n}$ = 7 + 4(n - 1) = 7 + 4n - 4 = 4n + 3

Please help area and perimeter of functions

nalin [4]

Answer:

= 150 square units

Step-by-step explanation:

Area of a right triangle is given by the formula;

1/2 bh ; where b is base and h is the height of the triangle

using Pythagoras theorem, we can find the height;

h² = 20² - 16²

h = √144

= 12 units

The base of the small triangle can also be found using Pythagoras theorem;

b² = 15² - 12²

b = √ 81

= 9

Therefore;

Area = 1/2 bh

= 1/2 × 12 × (16+9)

= 1/2 × 12 × 25

= 6 × 25

= 150 square units or 150 u²

What is the range of the function g(x) = [X – 12 – 2? o tyy-2) OVY 2-2) Oviy> 12) O y 2 12)

oksano4ka [1.4K]

The range of the function is: $\{y | y \ge -2 \}$

<h3>What is the range of a function?</h3>

The range of a function is the set of output values the function can take

The function is given as:

$g(x) = |x - 12| -2$

The above function is an absolute value function;

And it is represented as:

$g(x) = a|x - h| + b$

When a is positive, then the range of the function is:

$y \ge b$

By comparison, we have:

$a =1$

$b = -2$

Hence, the range of the function is: $\{y | y \ge -2 \}$
