The graph shows the height of a plant over time. What is the unit rate?

Anna35 [415]

Answer: unit rate = 1 / 5 = 0.2 inches per day

Step-by-step explanation:

The unit rate is the ratio that describes how one quantity changes as the other changes.You can find a unit rate from a graph the same way you find the slope.

1. Choose two points on the graph to find the slope

- (0,0) and (5,1)

x₁ y₁ x₂ y₂

2. Slope = y₂ - y₁ / x₂ - x₁ (This is essentially the change in y-coordinates divided by the change in x-coordinates.

unit rate = y₂ - y₁ / x₂ - x₁

unit rate = 1 - 0 / 5 - 0

unit rate = 1 / 5 = 0.2 inches per day

Help me please, Find a, b, and c.

Mama L [17]

Answer:

a = $6*\sqrt{3}$

b = 12

c = $6\sqrt{2}$

Step-by-step explanation:

Since the triangles are right triangles with 60 and 45 degree angles, their side lengths follow special triangles.

A 45-45-90 right triangle has side lengths $1-1-\sqrt{2}$ .

A 30-60-90 right triangle has side lengths $1 - \sqrt{3} -2$ .

Starting with the top triangle which has a 60 degree angle, its side length 6 corresponds to a side length of 1 in the special triangle. It is 6 times bigger so its remaining sides will be 6 times bigger too.

Side a corresponds to side length $\sqrt{3}$ . Therefore, $a = 6*\sqrt{3}$ .

Side b corresponds to side length 2, b = 2*6 = 12.

The bottom triangle has a 45 degree angle, its side length b= 12 corresponds to $\sqrt{2}$ . This means $\sqrt{2}$ was multiplied by $12 = \sqrt{2} * \sqrt{72}$ . This means that side c is $\sqrt{72}=6\sqrt{2}$ .
