Answer: C) 2 dimensions; flat surface of length and width, but no depth
One way to think of a plane is to think of a flat sheet of paper that extends infinitely in all directions. The paper must be kept flat without any bends.
A = k/R where A = acceleration and R = radius of the turn and k is a constant to be found.
Substituting the given values:-
10 = k / 70
k = 10*70 = 700
So the equation of the motion is A = 700 / R
When the radius is 140 the acceleration is 700 / 140 = 5 ft/sec/sec ( answer)
Cancel out the denominators.
(x+5)² + 18 = -30
(x+5)² = -30 - 18
(x+5)² = -48
The equation is impossible, we have a negative number.
There isn't a number that squared gives a negative number (the square is always positive).
√(x+5)² = +/- √-48
x+5 = +/- √-48
IMPOSSIBLE
You can write the result in imaginary numbers
x+5=+/- 4i√3
Answer:
135 square feet
Step-by-step explanation:
area of base and top=2(1/2×6×2.5)=15 square feet.
area of three faces=(2.5+6+6.5)×8=15×8=120 ft
total surface area=15+120=135 square feet.
Answer:
See below for answers and explanations
Step-by-step explanation:
Your table is a little weird, so I will try my best:
a) A linear regression equation for the line of best fit would be y-hat = 0.018x - 24.5111 where y-hat is the predicted value for the recorded weight gain (in pounds) and x is the additional daily caloric intake. You can put the data into lists and use the LinReg function on the TI-84 to get this equation.
b) It seems that as the pony's additional calorie intake increases, the weight gain also increases in pounds
c) Set x equal to 2300 and solve for y-hat:
y-hat = 0.018x - 24.5111
y-hat = 0.018(2300) - 24.5111
y-hat = 41.4 - 24.5111
y-hat = 16.8889
So our predicted value for the weight gain based on an additional 2300 calorie intake is 16.9 pounds.
