Item 3 What is the length of the base of a right triangle with an area of 15 m² and a height of 3 m? 5 m 10 m 30 m 45 m

10m

Step-by-step explanation:

Use the area of triangle:

Area of triangle =

1/2 × b × 3 = 15

b × 3 = 30

b = 30/3

b = 10

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
