Answer:

The answer is: A positive number with divisors besides one and itself is called a composite number.

Step-by-step explanation:

Unlike prime numbers, which can only be divided by one and themselves, composite numbers have other divisors apart from these two. All even numbers greater than two, for example, are composite numbers because of the fact that they can all be divided by one, themselves and the number two.

An example of a prime number is 11 (It can only be divided by 11 and 1)

An example of a composite numbers is 12 (It can be divided by 1, 2, 3, 4, 6 and 12)

If f(1) = 7 and f(n) = -3f(n − 1) then find the value of f(6).

ludmilkaskok [199]

Answer:

-1701

Step-by-step explanation:

The recursion relation tells you each term of the sequence is -3 times the previous term. Then the first 6 terms are ...

7, -21, 63, -189, 567, -1701

The value of f(6) is -1701.

Additional comment

The explicit formula for a geometric sequence with first term 7 and common ratio -3 is ...

f(n) = 7×(-3)^(n-1)

Then f(6) is ...

f(6) = 7×(-3)^5 = 7×(-243) = -1701

The model below represents 4 x + (negative 4) = negative 2 x + 8.

ikadub [295]

Answer:

x = 2

Step-by-step explanation:

4 x + (negative 4) = negative 2 x + 8

4x + (-4) = - 2x + 8

4x - 4 = - 2x + 8

4x + 2x = 8 + 4

6x = 12

$x = \frac{12}{6} \\ \\ x = 2$

The ratio of the number of Victor’s tools to the number of Ilya tools is 5:2. Victor has 42 more tools than Ilya. How many tools

AnnyKZ [126]

Answer: Victor should give 28 tools to Ilya.

Step-by-step explanation:

Since we have given that

Ratio of the number of Victor's tools to the number of IIya's tools = 5:2

Let the number of Victor's tools be 5x

Let the number of Ilya's tools be 2x

According to question, Victo has 42 more tools than Ilya.

So, our equation becomes,

$5x-2x=42\\\\3x=42\\\\x=\dfrac{42}{3}=14$

So, number of tools Victor has 5x=5×14=70

Number of tools Ilya has 2x = 2× 14 =28

Let the number of tools that Victor should give to Ilya be 'y' so that the ratio of the number of victor's tools to the number of Ilya's tools is 3:4.

According to question, it becomes,

$\dfrac{70-y}{28+y}=\dfrac{3}{4}\\\\4(70-y)=3(28+y)\\\\280-4y=84+3y\\\\280-84=3y+4y\\\\196=7y\\\\y=28$

Hence, Victor should give 28 tools to Ilya.

What’s the answer of g

Lunna [17]

Answer:

$\huge\boxed{g(a-1)=\dfrac{2-a}{a}=\dfrac{2}{a}-1}$

Step-by-step explanation:

$g(t)=\dfrac{1-t}{1+t}\\\\g(a-1)-\text{substitute}\ t=a-1\ \text{to}\ g(t):\\\\g(a-1)=\dfrac{1-(a-1)}{1+(a-1)}=\dfrac{1-a-(-1)}{1+a+(-1)}=\dfrac{1-a+1}{1+a-1}=\dfrac{(1+1)-a}{(1-1)+a}=\dfrac{2-a}{a}$

A map has a scale of 2 inches : 25 miles. Chandra uses the map to find the distance from the zoo to her house. The distance on t

geniusboy [140]

Step-by-step explanation:

Turn the ratio into a fraction

2in /25 mi

You want to have miles so you can flip the fraction and mutiply to cancel out the inches

(25mi / 2in) x 5in = (25 mi x 5in) / 2in
