The functions are illustrations of composite functions.
<em>The soil temperature at 2:00pm is 67</em>
The given parameters are:
---- the function for sun intensity
-- the function for temperature
At 2:00pm, the value of h (number of hours) is:
Substitute 8 for h in , to calculate the sun intensity
Substitute 8/9 for I in , to calculate the temperature of the soil
Approximate
Hence, the soil temperature at 2:00pm is 67

Answer:
EA
Step-by-step explanation:
Answer: 130
Step-by-step explanation:
--> first solve sqr-->2-64/4+144
-->perform division next as per DMAS rule-->64÷4=16--> 2-16+144
--> now perform addition and subtraction-->2-16-14--> -14+144= 130
Answer:
Yes, this is linear.
y = -4x
Step-by-step explanation:
12x = 7y - 10y
12x = -3y
-3y = 12x
/ -3 /-3
y = -4x + 0

Answer:
one side is 40 other is 50
Step-by-step explanation:
perimeter=180cm
let one side=length=x
Acc. to condition:
other side=width=x+10 (one side exceed other by 10)
perimeter= 2(length+width)
subtitue all values given above:
180=2(x+x+10)
180=2(2x+10)
2x+10=180/2
2x+10=90
2x=90-10
2x=80
x=40
now
lenght=x=40cm
width=x+10=40+10
width=50cm
