Answer:
3√2
Step-by-step explanation:
The length of the diameter is given by the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-4))² +(8 -14)²) = √(36 +36) = 6√2
The radius is half the diameter, so the radius of your circle is 3√2.
Answer:
Step-by-step explanation:
Length of the bridge = 190 m = 190*100 = 19000 cm {100cm = 1m}
Length of each pace of Robert = 80 cm
Minimum number of full paces = 19000/80
= 237.5
= 238 {because full paces}
3x < -6
x < -6/3
x < -2
Therefore, the solution set is {x | x < -2}.
Answer: He spends more time trading stickers by 15 minutes.
Step-by-step: 1 hour is 60 minutes. So 2 hours is 120 minutes. 120 minutes plus his 20 minutes is 140 minutes. Subtract it from his homework time and he spends 15 more minutes trading stickers.
F(x) = 3x^32 + 8x^2 -22x +43
The ends of all the polynomials with even degree behave like quadratic functions.
Given the the coefficient of x^32 is positive, the function opens upwards. Then the two ends go up.
