Answer: E. 99

Step-by-step explanation:

A composite number has more than two factors which means not only including 1 and itself, but at least one other.

factor of 29: 1, 29

factor of 41: 1, 41

factor of 71: 1, 71

factor of 79: 1, 79

factor of 99: 1, 3, 9, 11, 33, 99

Clearly 99 has more than two factors.

Hope this helps!! :)

AnnyKZ [126]

Answer: The boat moved 768.51 feet in that time .

Step-by-step explanation:

Since we have given that

Height of the lighthouse = 1000 feet

Angle depression to boat 'a' = 29°

Angle of depression to shore 'b' = 44°

Consider ΔABC,

$\tan 44\textdegree=\frac{AB}{BC}\\\\\tan 44\textdegree=\frac{1000}{BC}\\\\BC=\frac{1000}{\tan 44\textdegree}\\\\BC=1035.53\ feet$

Now, Consider, ΔABD,

$\tan 29\textdegree=\frac{AB}{BD}\\\\\tan 29\textdegree=\frac{1000}{BD}\\\\BD=\frac{1000}{\tan 29\textdegree}\\\\BD=1804.04\ feet$

We need to find the distance that the boat moved in that time i.e. BC

so,

$DC=BD-BC\\\\CD=1804.04-1035.53\\\\CD=768.51\ feet$

Hence, the boat moved 768.51 feet in that time .

A lawn-mowing company is trying to grow its business. it had 30 clients when they started its business and wants to increase by

Leona [35]

The function to represent the problem is f(x)=6x+24 and the range is 30 $\leq$ y $\leq$ 48.

<h3>What is arithmetic sequence formula?</h3>

If the terms of a sequence differ by a constant, we say the sequence is arithmetic. If the initial term ( $a_{0}$ ) of the sequence is a and the common difference is d, then we have,

$a_{n}$ =a+(n-1)d

Initial number of clients=30

Number increase per week= 6

So, we can make an arithmetic sequence fir six weeks

30,36,42,48

Here, first term, a=30

Common difference, d=6

Range is [30,48]

The explicit formula of an arithmetic sequence is

$a_{n}$ =a+(n-1)d

Put a=30, d=6, n=x

$a_{x}$ =30+(x-1)6

$a_{x}$ =30+6x-6

$a_{x}$ =6x+24

Therefore, The function to represent the problem is f(x)=6x+24 and the range is 30<=y<=48
