Answer:
Step-by-step explanation:
The equation for exponential decay function is given as:
where:
D(t)= difference in temperature t=time
r=rate of change
a =initial value of the temperature
From the given problem:
Initial Temperature,a=50°C
Rate of Decay,r=
Therefore the function for the difference in temperature is given as:
We can convert 
to decimal and write the function as:

f(x)=7x+2
f(-1)=7(-1)+2=-7+2=-5
f(3)=7(3)+2=21+2=23
f(5)=7(5)+2=35+2=37

Given f(x)=10x+4 and g(x)=3x-8
f(x)+f(x)=(10x+4)+(3x-8)=13x-4
13x-4
Question 49
f(x)=x²-3x and g(x)=4x⁵
f(x)*g(x)=(x²-3x)(4x⁵)=4x⁷-12x⁶
4x⁷-12x⁶
Question 50
(0,3)
f(x)=-2x/3 + 2
f⁻¹(x)=-3x/2+3
f⁻¹(0)=3

A parallelogram has to have a total of 360 degrees in angles, so we take 59 x 2 to get 118, we then subtract 118 from 360, 360 - 118 = 242, we then divide by two because a parallelogram has 2 obtuse angles, giving us an answer of 121 degrees. Hope this helps
