Answer:

option C. -\frac{5}{13}

Step-by-step explanation:

we have  that

The point (-5,-12) belong to the III quadrant

so

The value of the cosine is negative

Applying the Pythagoras Theorem

Find the value of the hypotenuse

h^{2}=5^{2}+12^{2}\\ h^{2} =25+144\\ h^{2}=169\\h=13\ units

The value of cosine of angle θ is the ratio between the side adjacent to angle θ and the hypotenuse

cos(\theta)=-\frac{5}{13}

You put $1000 in a savings account which earns compound interest at a rate of 0.1% per month. If you don't make any deposits or
Andre45 [30]
Amount in compound interest = p(1 + r)^n where p is the initial deposit, r = rate and n = period.
Here, Amount after 36 months = 1000(1 + 0.1/100)^36 = 1000(1 + 0.001)^36 = 1000(1.001)^36 = 1000(1.036637) = $1,036.64

I'd really appreciate it if anyone could help! :)
Ahat [919]

Answer:

The given table represents a function f(x) = y = 2x+3

The upper graph

Step-by-step explanation:

We will write the equation of the right line in the explicit (slope) form

y = ax+b

We will take two points from the given table

A(-1,1) and B(0,3) and insert their coordinates in the equation y=ax+b and get

A(-1,1)  => 1 = (-1)*a+b => -a+b=1

B(0,3) => 3=0*a+b => 3= 0+b => b=3

Now we will insert b=3 in the equation -a+b=1 and get

-a+3=1 =>  a=3-1 => a=2

Now we will insert a=2 and b=3 in the equation y=ax+b and get

equation of the function  

y = 2x+3 = f(x)  The upper graph.

Good luck!!!
