Answer: No it is not.
Step-by-step explanation:
All linear functions can be written in the form y = mx + b, where m is the slope and b is the y-intercept (slope-intercept form). Alternatively, a linear function can be expressed in the form y – y0 = m(x – x0), where m is the slope and (x0, y0) is a point on the line (point-slope form).
The way tires on wheels work is that when the wheel turns one complete
turn, it moves (forward or backward) by a distance that's the circumference
of the tire.
Now, we know that the circumference of a circle is (π) times the diameter.
The diameter of the tire on this bus is 1 meter. So its circumference is
(π · 1 meter), and every time it turns once, the bus moves 1 meter down
the road.
If the tire rotated 8,000 times, then the bus moved 8,000π meters,
or 8π kilometers.
THAT's the exact answer. If you want to know how far that actually is,
then you take some number that's approximately π and multiply it by
8 km. You can never get an exact answer like that, because you can
never write the exact value of π with digits.
In school, we often use ' 3.14 ' for π . If you do that, then the bus
traveled
(8 km) x (3.14) = 25.1 kilometers .
When you do that, you have to remember that it's approximate.
If you want an exact answer, then you have to leave π in the answer.
x of 3/4 = x10 abd y 19/2 or 11
I’m not sure if you are solving for y or x but if you are solving for y it’s
y=(2(9+x^2))/(1-6x)
or if your solving for x it is
x= (-3y+ sqr(9y^2+2y-36)) / (2)
Answer:
$378
Step-by-step explanation:
Full price: 1.00($450) = $450
20% off: 0.20($450) = $90
Sale price (after 20% off): (1.00 - 0.20)($450) = 0.80($450) = $360
Final price, including tax: (1.00 + 0.05)($360) = $378
