When a baby panda is born, it is 6cm in length. Every week after this, its size increases by 5 cm. Write an equation in slope in
Neporo4naja [7]

Answer:

56cm, y=5x+6

Step-by-step explanation:

The baby panda's initial or starting length is 5cm. This is the y-intercept or b value. We also know that the panda increases every week by 5 cm. This is the rate of change or slope. This is m. We can write in slope-intercept form y=mx+b.

y=5x+6

We substitute x=10. y=5(10)+6=56cm

A surveyor is calculating the width of a canyon. He has taken the measurements shown below. What is the width of the canyon? Typ
Serga [27]

Answer:

480 ft

Step-by-step explanation:

To find the width (x), apply the similarity theorem of two similar triangles, which says that the corresponding lengths of two similar triangles are proportional.

Thus:

x/72 = 80/12

Cross multiply

12 × x = 80 × 72

12x = 5,760

12x/12 = 5,760/12

x = 480

Width of the canyon = x = 480 ft
