F(1)=6;f(n)=f(n−1)−2
ch4aika [34]

Answer: f(7) = f(4) + 3(3) = 15 + 9 = 24

Step by Step Explanation:

f(1) = 6

f(n) = f(n-1) + 3

 

f(2) = f(1) + 3 = 6+3 = 9

f(3) = f(2) + 3 = 12

f(4) = f(3) + 3 = 15

 

Each term is 3 more than the previous one  

Therefore to get from the 4th term to the 7th term you will add 3

For a total of 3 more times.

 

f(7) = f(4) + 3(3) = 15 + 9 = 24

Hope this helps

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2
Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: 3x - 2

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: -9y

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: -7x^2 + 4x

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: -\frac{1}{2} x^2

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: 8xy

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

If the circumference of a circle is 36π, what is the length of a radius of the circle?
m_a_m_a [10]

Answer:

The answer is 6 (A)

Step-by-step explanation:

The exact answer is 5.73, but I think in the question they are rounding to the nearest whole number, so the rounded answer is 6.

My work:

C = 2πr

r = C

2π = 36

2·π = 5.72958

52<br> Х<br> degrees<br> PLEASEHEHEH
Tom [10]

Answer:

x = 142 degrees

Step-by-step explanation:

52 + 90 + x = 180

142 + x = 180

-142        -142

-------------------

        x = 38

180 - 38 = 142

Hope this helped.
