The area formula of a circle is π×
pi is 3.14 and r is the radius. The question gives you the diameter. To find the radius with a given diameter, divide the diameter by 2. 24÷2=12. The radius is 12. Now we can multiply 3.14×
do the exponents first. 12×12=144. Now multiply that by pi. 144×3.14=452.16
Answer: c
Step-by-step explanation:
Answer: 1,425 students
Step-by-step explanation: This is easy to solve using proportions/
114/8 = ?/100
First, you cross multiply (or whatever this is called sry) 100x114=11400
Then divide 11400÷8=1,425
Answer:
yes (at about (22, 66)
Step-by-step explanation:
If you subtract 3 times the horizontal distance, the equation becomes ...
yv -yh = (0.006x^3 -0.06x^2+1.4x) -(3x) = 0.006x^3 -0.06x^2 -1.6x
The signs of the terms are +--, so Descartes' rule of signs tells us the one sign change indicates one positive real root. That is this difference will be zero for some positive value of x.
Yes, it is possible.
_____
The graph shows the condition will be met near x=22.
Answer:
4x - 4 -9x + 6 = 12x + 24
arrange like terms
-5x +2 = 12x + 24
or, -17x = 22
x = - 22/17
