A car drives 215 km east and then 45 km north. What is the magnitude of the car's displacement? Round your answer to the nearest whole number. km
Answer:
220 km
Step-by-step explanation:
Since the direction north is perpendicular to the direction east, the driver has covered the two legs of a right triangle. The hypotenuse is his displacement for the combination of the two segments.
D = √(215² + 45²)
= √(46,225 + 2,025)
= √48,250 = 219.6588... km
Nearest whole number: 220 km
Answer:
220

Leona tracks her calories burned while boxing. The number of calories she burns is expressed by the function c(t) = 425t, where t is the number of hours spent boxing.
To burn more calories, Leona wears heavier gloves while boxing. The number of calories she burns while wearing heavier gloves is expressed by the function b(c) = 1.1c, where c is the number of calories burned while boxing without heavy gloves.
Which of the following composite functions expresses the calories, as a function of time, that Leona burns while boxing with heavy gloves?
c[b(t)] = 467.5t
c[b(t)] = 426.1t
b[c(t)] = 467.5t
b[c(t)] = 426.1t
Answer:
C. b[c(t)] = 467.5t

What is the domain of the following graph? Please don't put links down I cant download them.
Answer:
-infinity, infinity
Step-by-step explanation:
Domain is x, and in a quadratic equation like this one the x axis goes on forever. So the first answer of -infinity, infinity is correct.
Answer:
(-inf, inf)
Step-by-step explanation:
Remember, the domain of the function looks at purely the input values (x-axis), not your output values (y-axis).
Keeping this in mind, you can see that the x values stretch from the far left, -inf to the far right +inf.
Remember, as infinities aren't considered actual values, you put them in parentheses. This means your answer is (-inf, inf).
Lucy earns 5(x+12) for mowing 5 lawns. What does x+12 represent? Fill in the blank: The (blank) per lawn. (*hint: the blank is one word lower cased).
Answer:
(x+12) = cost per lawn
Step-by-step explanation:
Given data
Lucy earns 5(x+12) for mowing 5 lawns
From the expression given the number of lawns is 5
Hence (x+12) represents the cost of lawning 1 lawn
That the amount collected to lawn a lawn

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Step-by-step explanation:
Ok
Had to solve in the comment section because I couldn't find the answer button before. It Just appeared Lol.
You can still check the solution in the first guy's comment section
d=vt will represent the Motion of Both persons
for Karen
d=59t
for Ricardo
d=65t
They're both 279miles away from each other
Meaning
Dk + Dr = 279
59t + 65t = 279
124t=279
t=279/124
t= 2.25hrs.
You can change to seconds if thats how the answer waa presented.
The area of a square in square feet is represented by z^(2)+12z+36. Find an expression for a side length of the square.
Answer:
Side is equal to [tex](z+6)[/tex] feet.
Step-by-step explanation:
A square is a four sided polygon in which all sides are equal, diagonals are equal and each angle is equal to [tex]90[/tex]°
Area of a square = side × side
Area of a square [tex]=z^2+12z+36[/tex]
Here, write [tex]12z=6z+6z[/tex]
Therefore,
Area of a square [tex]=z^2+6z+6z+36[/tex]
[tex]=z(z+6)+6(z+6)[/tex]
[tex]=(z+6)^2[/tex] square feet
So,
side × side [tex]=(z+6)^2[/tex]
This implies side is equal to [tex](z+6)[/tex] feet.

Answer:
y = -x/16 +1
Step-by-step explanation:
The slope is at any point x is ...
y' = -4/x^2
so, at x=8, the slope is ...
m = -4/8^2 = -4/64 = -1/16
The point-slope form of the equation of the line is ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
Then the line with slope -1/16 through point (8, 1/2) is ...
y - 1/2 = -1/16(x -8)
y = -1/16x +1/2 + 1/2 . . . . . eliminate parentheses, add 1/2
y = -1/16x +1 . . . . . equation of the tangent line
