Answer:
Step-by-step explanation:
Step 2: 2.8z - 3.4z - 7.2 + 6.6
Step 3: -0.6z - 0.6
-7 (-15w + 21) + 3(18 - 27w)
step 1: 105w - 147 + 54 - 81w
Answer:
11.45 lumens
Step-by-step explanation:
We are given that
Where x=Depth
I=Intensity of light
We have to find the intensity of the light at a depth of 20 feet.
Substitute the value of x
Hence, the intensity of the light (in lumens) at a depth of 20 feet=11.45 lumens
The first term is -43.
Explanation:
an = a + (n - 1)d
a12 = a + 11d = 56, first equation
a21 = a + 20d = 101, second equation
Subtract the second equation from the first equation, cancelling +a and -a
11d - 20d = 56 - 101
-9d = -45
d = 5
Subtitute d into the first equation
a + 99 = 56
a = -43
a refers to the first term, hence the first term is -43.
Answer:
1919=0+1+0+1=2
Step-by-step explanation:
Answer:
P = 16
Step-by-step explanation:
Given
5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation
5(4) = 2P + 3(- 4), that is
20 = 2P - 12 ( add 12 to both sides )
32 = 2P ( divide both sides by 2 )
16 = P
