The answer is 3k+j since 3 cannot be multiplied after k.
Answer:
x = 8
Step-by-step explanation:
12x +12 = 3x +84
12x +12 -12 -3x = 3x -3x +84 -12
12x -3x = 84 -12
9x = 72
9x/9 = 72/9
x = 8
Answer:
The area of the label is 176,000 cm²
Step-by-step explanation:
The given parameters are;
The radius of the cylindrical container, r = 14 cm
The height of the cylinder, h = 20 m
The area covered with the label = The curved surface of the cylinder, A
The curved surface area of a cylinder, A = 2 × π × r × h
π = 22/7
∴ The curved surface area of the cylinder = A = 2 × 22/7 × 14 × 2000 = 176,000
A = 176,000 cm²
∴ The area of the label = The curved surface area of the cylinder = 176,000 cm².
Hello,
Is you use windows 's calculator (in scientific mode)
Tape 88.2245 INV DEG ===>88,379166666666666666666666666667
and then beeing in degree TAN
==> 35,340151061377471313154648875558
There are no exact value.
Answer: First question: D, Second question: A
Step-by-step explanation:
Note: I'm not so good at expanding so I'll just solve it :)
So this leaves either C or D
Apply the sum rule:
8-70=-62
The only one that gives a negative sum is D
For the second picture, the one you have chosen is correct
a1 = 3 and r = -5 so:
an = 3/5 * (-5)^n
Plugging in 8 for n (the first choice) we get the given term: -234,375
