How does tan 135 degrees compare to tan -135 degrees

Anna007 [38]

Evaluating the tangent function for the two values we obtain the following:
tan 135=tan(135+180)=tan 315=-1

next:
tan -135=tan(180-135)=tan 45=1
thus comparing the two we see that tan 135 is negative while tan -135 is positive

A bacteria culture initially contains 100 cells and grows at a rate proportional to its size. After an hour the population has i

Assoli18 [71]

Step-by-step explanation:

Rate of growth equals 420/100 = 4.2 times per hour

So after t=three hours,

size of culture = 100*(4.2)^t = 100*4.2^3=7408.8 bacteria,

round to nearest unit 7409 bacteria after three hours (after initial size of 100).

Harman [31]

Answer:

The required expression is: $\mathbf{\frac{5(x+y)}{-8x}}$

Option C is correct option.

Step-by-step explanation:

We need to find the equation that fits the description.

a) the expression is the quotient of two quantities

The quotient is expressed as $\frac{a}{b}$

where a is numerator and b is denominator

b) The numerator of the expression is product of 5 and the sum of x and y

Sum of x and y = x+y

Product of 5 and Sum of x and y = 5(x+y)

So, Numerator of the expression is 5(x+y)

c) The denominator is the product of negative 8 and x

Product of negative 8 and x = -8x

So, denominator of the expression is -8x

Now, The required expression is: $\mathbf{\frac{5(x+y)}{-8x}}$

Option C is correct option.
