Given:
Amplitude of cosine function, A=3.
Period, T=7π/4.
Midline, D=2.
The time period can be expressed as:
Put T=7π/4 to find the value of B.
The general cosine function can be expressed as,
Substitute B=8/7, A=3 and D=2 in above equation.
Therefore, the cosine function is,

I think first you must Unification of denominatorsit will 60 for (3,4,5) so you will get
2\5 = 24\60
1\4 = 15\60
1\3 = 20 \60
then you divide each one apart then multiply by total number (3,800)
so :
24\60 * 3800 = 1520
15\60 * 3800 = 950
20 \60 * 3800 = 1267
_____
note : when you will gather results you will get Approximate number to 3800
i hope i helped
Answer:
Step-by-step explanation:
Area of triangle is 40 cm² correct to nearest 5cm² .
∴ Area of triangle = ( 40 ± 5) cm²
∴ upper bound for area of triangle is = (40 + 5) cm² = 45cm²
Base of triangle = 9cm
∵ area of triangle = 1/2 base × height
height = 2 × area of triangle/base
∴ upper bound for height of triangle = 2 × upper bound area/base
= 2 × 45/9 = 10cm
Hence answer is 10cm
You could use an equation like y=6x
