Answer:
- No, there is no proportional relationship
Step-by-step explanation:
<u>The proportional relationship is:</u>
- y = kx, which is a special form of linear equation, with zero y-intercept
<u>In the given case we have:</u>
This is a linear function but not proportional relationship because it has y-intercept, different than zero
Answer:
they are equal
Step-by-step explanation:
f(x) means the same thing as y.
The smallest region that can be photographed is
5*7 = 35 square km
so we want to know how long it takes to zoom out to an area of
35 * 5 = 175 square km.
Notice that the length and width increase at the same rate, 2 km/sec, and they start out with a difference of two, so when the width has increased from 5 to x, the length will have increased from 7 to x+2. At the desired coverage area, then,
x(x+2) = 175
x^2 + 2x = 175
x^2 + 2x + 1 = 176 [completing the square]
(x+1)^2 = 176
x+1 = ±4√11
x = -1 ±4√11
Since a negative value for x is meaningless here, x must be
-1 + 4√11 = about 12.27 km
and the time it took to increast to that value was
(12.27 - 5) km / (2 km/sec) = about 3.63 seconds
Answer:
Always.
Step-by-step explanation:
That is the reason why when you are trying to calculate the area of a triangle you do the base x height divided by two or in half. If you printed out the triangle twice then cut it out and put the two together it would be a rectangle.
Answer:
50?
Step-by-step explanation:
I said 50 because there were 60 na butterflies so there was probably 50.
I am sorry if this wrong tho
