Answer:
15x-2+7x+4=90°[being complementary angle]
22x+2=90°
22x=90°-2
22x=88
x=88/22
x=4
0.035 is 35/1000, which is 7/200 when you take out a 5 from both sides.
The domain of f(x) = -6x^2 - 10x + 13 is all real values.
For the range f(x) = -6x^2 - 10x + 13 written in vertex form is -6(x^2 + 5/3x - 13/6) = -6(x^2 + 5/3x + 25/36 - 13/6 - 25/36) = -6(x + 5/6)^2 - 6(-103/36) = -6(x + 5/6)^2 + 103/6
Range is all real values less than or equal to 103/6
We determine the kilowatt-hour by multiplying the energy in kilowatt and the time in hours. We do as follows:
kWh = 110 W ( 1 kW / 1000 W ) (215 hrs )
kWh = 23.65 kWh
Hope this answers the question. Have a nice day.
Answer:
y = - 6x
Step-by-step explanation:
Note the relation between x and y points on the table, that is
x = - 2 → y = 12
x = - 1 → y = 6
x = 1 → y = - 6
x = 2 → y = - 12
x = 3 → y = - 18
By inspection the y points are x multiplied by - 6, hence
y = - 6x ← is the equation relating x and y
