Answer C and D please

Mathematics
1 answer:
DENIUS [597]3 years ago
6 0

Answer:

C. solution:

3(3c-2) = 5(2c-1)

or, 9c-6 = 10c-5

or, -6+5 =<em> </em>10c-9c

or, -1 = 1c

Hence, c = -1.

D. solution:

5(5-2a) = 4(6-a)

or, 25-10a = 24 - 4a

or, 25-24 = -4a+10a

or, 1 = 6a

or, 1/6 = a

Hence, a = 1/6.

The fish population of a lake is decreasing each year. A study is conducted. But, unfortunately some data was lost. The research
Solnce55 [7]

Answer:

F(t) = 18000(0.6666)^{t}

Step-by-step explanation:

The fish population after t years can be modeled by the following equation:

F(t) = F(0)(1-r)^{t}

In which F(0) is the initial population and r is the constant rate of decay.

Year one the fish population was 18000

This means that F(0) = 18000

In year three the fish population was 8000 fish.

Two years later, so F(2) = 8000

F(t) = F(0)(1-r)^{t}

8000 = 18000(1-r)^{2}

(1-r)^{2} = 0.4444

\sqrt{(1-r)^{2}} = \sqrt{0.4444}

1 - r = 0.6666

r = 0.3334

So

F(t) = 18000(0.6666)^{t}

If cos theta is -5/13 and sin θ &lt; 0, what is tan θ ?
tensa zangetsu [6.8K]
Take the right angled triangle  with sides 13, 12 and 5. sine theta will be 12/13

When sin theta < 0 and cos theta < 0  we are in the  third  quadrant  so sin theta will be -12/13

tan theta = sin theta / cos theta  = -5/13 /  -12/13   = -5*13 / -12*13 =  5/12
