can you assume that any fraction is in simplest form if either the numerator or denominator is a prime number?

In most cases, if both the numerator and the denominator of a fraction are prime for example in the fraction 2/5 the greatest common factor of the numerator and denominator will be 1 which means that the fraction is in lowest terms.

However, if the numerator and the denominator are the same prime number for example 7/7 the fraction is not in lowest terms because the greatest common factor is the prime number in this case 7.

7/7 can be written in lowest terms as 1/1 therefore if the numerator and denominator of a fraction are both prime, the fraction is not always in lowest terms so the given statement is false.

Answer:

some occasions yes and other no for example if a fraction was 3/9 the numerator is prime but the fraction can still be simplified to 1/3 but a number were 3/5 then you wouldn't be able to simplify it

A sequence is defined recursively by the following rules: f(1)=3f(n+1)=2⋅f(n)−1 Which of the following statements is true about

Radda [10]

Answer:

f(2)=5

f(5)=33

Step-by-step explanation:

The given formula, that recursively defines the sequence is

$f(1) = 3 \\ f(n + 1) = 2f(n) - 1$

When n=1, we obtain;

$f(1+ 1) = 2f(1) - 1 \\ f(2) = 2 \times 3 - 1 \\ f(2) = 6 - 1 \\ f(2) = 5$

When n=2, we get:

$f(2+ 1) = 2f(2) - 1 \\ f(3) = 2 \times 5 - 1 \\ f(3) = 10 - 1 \\ f(3) = 9$

When n=3,

$f(3 + 1) = 2f(3) - 1 \\ f(4) = 2f(3) - 1 \\ f(4) = 2 \times 9 - 1 \\ f(4) = 18 - 1 \\ f(4) = 17$

When n=4

$f(4 + 1) = 2 f(4) - 1 \\ f(5) = 2 \times 17 - 1 \\ f(5) = 34 - 1 \\ f(5) = 33$

When n=5,

$f(6) = 65$

What is five fourths of a right angle

MrRa [10]

A right angles is 90 degrees
if you mean 5/4 of the MEASURE of a right angle then
90 times 5/4 (because in math 'of' means multiply)
90 tmes 5/4=450/4=225/2=112.5 degrees

What is the best name for the figure with vertices at the following coordinates? (0,0), (-1, 1), (6, 1), and (2, 0)

algol [13]

We are given with the following vertices:
A (0,0)
B (-1,1)
C(6,1)
D (2.0)

Next is to plot the vertices in the Cartesian plane so that we can identify the figure. See attached image.

The identified shape is a "Parallelogram".
