Answer:
Sin x = a / b.
Step-by-step explanation:
The opposite side =a and the adjacent side = 4 (because tan x = a/4.
Cos x = 4/b so the hypotenuse = b ( because Cos = adjacent /hypotenuse.
So sin x = opposite /hypotenuse = a / b.
Answer:
94%
Step-by-step explanation:
4,700/5,000 x 100%
0.94 x 100% = 94%
Answer:
x/y=1/4
Step-by-step explanation:
3x+2y=3y-2
3x=3y-2y-2
3x=y-2
y=3x+2
x+y=10
x+3x+2=10
4x+2=10
4x=10-2
4x=8
x=8/4
x=2
2+y=10
y=10-2
y=8
x/y=2/8=1/4
Answer:
A
Step-by-step explanation:
For functions with x in the denominator we want to make sure the denominator isn't 0. If x can't be -2 then the answer is A because x = -2 results in f(x) = 1/0 which is undefined.
Answer:
4550 kilowatt
Step-by-step explanation:
Given that :
Amount of energy produced per hour by solar energy system = 9.1 kw per hour
Number of hours for which electricity is produced per day = 5 hours
How much energy will be produced in 100 days
Number of kilowatt of energy produced per day:
Energy produced per hour * number of hours
9.1 kw per hour * 5 hours = 45.5 Kilowatt per day
In 100 days :
Daily energy produced * number of days
45.5 kilowatt * 100 days
4550 kilowatt
