ANSWER
Frequency=2
Midline =3
Amplitude =5
Period =π
EXPLANATION
We have:

The given function is of the form;

where
a=|5| =5 is the amplitude
and b=2 is the frequency.
and 2π/b=2π/2=π
The range of the given function is
8≤y≤-2
The midline is

Given:
Amount = Rs. 34476
Rate of compound interest = 4%
Time =
years
To find:
The principal value.
Solution:
Formula for amount is

Where, P is principal value, r is rate of interest and t is time in years.
Putting the given values, we get




Now,


Therefore, the value of sum or principal value is Rs.31256.
Answer:
2.3 hours, or 2 hours & 18 minutes
Step-by-step explanation:
we are trying to find h when d is 56.68, so I replaced d with 56.68

subtract 0.1 from both sides

divide both sides by 24.6
Answer:
42
Step-by-step explanation:
3x^2 +5x
Let x=3
3(3)^2 +5(3)
3*9 +15
27+15

Answer:
DEC+DEF=180
DEC=180-116
DEC=64°
in triangle DCE
angle D+angle C+angle E=180
7y+6+4y+64=180
11y+70=180
11y=180-70
11y=110
y=110/11
y=10°
angle C=4y
=4(10)
=40°
