Answer:
<C =120
Step-by-step explanation:
Since the figure in inscribed in the circle, <A = <C and <B = <D
<B= <D
2x-1=3x-59
Subtract 2x from each side
2x-2x-1=3x-2x-59
-1= x-59
Add 59 to each side
-1+59 = x-59+59
58 =x
<A = 2x+4
<A= 2(58) +4
= 116+4
<A =120
<C = <A
<C =120
The pollution level in 1980 was 7.13 to the nearest hundredth ⇒ answer c
Step-by-step explanation:
The function
, where
- p(t) is the population level at any time t
- t is the number of years after 1970
We need to find the pollution level in 1980
∵ 
∵ t is the number of years after 1970
∴ t = 1980 - 1970 = 10 years
- Substitute the value of t in the equation above
∴ 
∴ 
∴ p(t) = 7.13214 ≅ 7.13 to the nearest hundredth
The pollution level in 1980 was 7.13 to the nearest hundredth
