To get the area of the cone we need to find the radius first.
tan 70=r/12
r=12tan 70
area of a circle is given by:
A=πr²
thus the area of the ground covered by the tent will be:
A=π(12tan70)²
The answer is
A] A=π(12tan70°)²
Zeros of this function
- x²-x-6=0
- x²-3x+2x-6=0
- x(x-3)+2(x-3)=0
- (x+2)(x-3)=0
- x={-2,3}
ZEros of reciprocal function
The equation
- x²-(-1/2+1/3)x-(1/2)(1/3)=0
- x²-1/6x-1/6=0
ration? You deserve better from your teacher.
The ratio of auditorium to theater seats is
1200:320
That's a perfectly valid answer and we could stop here if we weren't asked for lowest terms. Here I can see that 12 and 32 have a common factor of 4 and both these end in zero so 40 is a common factor:
1200:320 = 30:8
We can keep reducing by another factor of 2,
1200:320 = 30:8 = 15:4
There's our 15/4, which we get when we write the ratio as a fraction.
Answer: 15/4
--------------------------
This question implies a ratio is just a fraction, which it isn't. Let's quickly note the differences.
A ratio can have zero on either side; 1:0 is a perfectly valid ratio but 1/0 is not a valid fraction. A ratio can't be all zeros -- that's not allowed.
A ratio can have more than two numbers. 3:4:5 is a common ratio that gives rise to a right triangle.
Like fractions, ratios can be reduced: For λ≠0,
λa : λb : λc = a:b:c
Answer:
the real answer is -1/3
Step-by-step explanation:
6lyl +6=4 subtract 6 from both sides
6lyl =-2 divide both sides by 6
lyl = -1/3
But absolute value is always a positive quantity, so this is impossible.....
