Answer:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0)

y-int: (0, 2)

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0) ==> When y=0

y-int: (0, 2) ==> When x=0

Place these foods in order of their vitamin C content, from highest to lowest.
castortr0y [4]

Answer:

½ c raw red bell pepper  (190 mg per cup)

1 medium orange  (96 mg per cup)

½ cup cooked broccoli (81 mg per cup, uncooked)

¾ cup tomato juice  (44 mg per cup, 33 mg in 3/4 cup)

Explanation:

Even if the reference measurements is 1 cup the proportion of vitamin C is maintained when half a cup of the measure is used.

As I do not know the size of the orange I am considering that half an orange is equal to half a cup.

Brococoli is cooked and Vitamin C is vulnerable to the cooking process and breaks down easily. So its vitamin C content will vary depending on how it was cooked and how long it lasted.

If an object turns but maintains the same speed,has its acceleration changed?explain
Andreas93 [3]
Acceleration is defined as the rate of change of velocity
Since velocity is a vector, it has both speed and direction.
So, if the object is travelling in a straight line at a constant speed, then it will not be accelerating. Both Magnitude and direction are constant.
However, if the object is travelling in a circle at a constant speed, then it'll be accelerating. An Object going in a circle is constantly changing it's direction, which means velocity is changing, so there is an acceleration caused by a net force.
Hope this Helps :)
