M and N complimentary angle
3x+8x-40=180
11x=220
x=20
a. 20 because y is the amount of $$ in account now
b. 12 a $$
c. 260, bc 12*20= 240 240+20=260
Answer:
Discontinuity of function occurs when x = 4 or x = -4
zero of function is when x=0
Step-by-step explanation:
We are given:

Discontinuity of the function occur when the denominator is equal to zero.
So, we need to find the values of x that makes the denominator zero.
The denominator is x^2 - 16
x^2 - 16 =0
x^2 = 16
x = ± 4
So, if the value of x = 4 or value of x=-4 then the function will be discontinuous.
Zero of the function i.e f(x)=0
So, Putting the function equal to zero and finding the value of x

So, zero of function is when x=0
The surface area of a rectangular prism is:
A=2(xy+xz+yz) where x,y, and z are the dimensions, in this case:
A=2(312*114+312*2+114*2)
A=2(35568+624+228)
A=2(36420)
A=72840 ft^2
We are given the exponential expression f(x) = Ca^x that should pass through the points (0,4) and (3,32). In this case, we first substitute the first point, (0,4) to the function to yield 4 = Ca ^0; hence Ca is equal to 4. The final expression hence is f(x) = 4^x
