Law of cosines.Anyone good in Trigonometry?

marin [14]

Answer:

$c=11.8\ units$

Step-by-step explanation:

we know that

The formula of law of cosines is equal to

$c^2=a^2+b^2-2(a)(b)cos(C)$

where

a, b and c are sides. C is the angle opposite side c

In this problem we have

$a=3\ units\\b=10\ units$

$C=120^o$

substitute the given values

$c^2=3^2+10^2-2(3)(10)cos(120^o)$

$c^2=109-(60)cos(120^o)$

$c^2=109-(60)(-0.5))$

$c^2=109+30$

$c^2=139$

$c=11.8\ units$

The sum of the first 6 terms of a geometric series is 15,624 and the common ratio is 5.

nikitadnepr [17]

Answer:

Step-by-step explanation:

The sum of n terms of a geometric series with first term a1 and common ratio r is given by ...

Sn = a1·(r^n -1)/(r -1)

for r=5 and n=6, this becomes ...

15624 = a1·(5^6 -1)/(5 -1) = a1·(15624/4)

Then we have ...

1 = a1/4 . . . . . divide by 15624

4 = a1 . . . . . . multiply by 4

The first term of the series is 4.

Please help me that’s would be great and I promise to mark brainlest!!

Option A is correct.

If we evaluate the function at $x=0$ , i.e. at the beginning, we have

$f(0)=75 \cdot 2^0 = 75 \cdot 1 = 75$

with each minute, you multiply the current number of cell by 2, so they double every minute.

Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be

$f(x) = 75 + 2k$

Option C is incorrect, because after one minute (i.e. when x=1) we have

$f(1) = 75\cdot 2^1 = 75 \cdot 2 = 150$

cells, so 75 is not the number of cells after one minute

Option D is incorrect in both the initial value and the behaviour of the function
