Answer:
the top right is the only function
Step-by-step explanation:
a function is defined as any set of points for which one x value only has one y value
The answer would have to be 5
Answer:
The answer is 243 patches.
Step-by-step explanation:
Area of a rectangular piece of fabric = 15 × 9 = 135 cm²
Area of 27 pieces of fabric = 135 × 27 = 3645 cm²
Number of patches can be cut from = 3645 ÷ 15 = 243
Height of the flagpole before it broke was 32 m
Step-by-step explanation:
- Step 1: This forms a right angled triangle with height 7 m and base 24 m. Find the hypotenuse using the Pythagoras Theorem.
Hypotenuse² = Base² + Height²
= 24² + 7² = 576 + 49 = 625
∴ Hypotenuse = √625 = 25 m
- Step 2: Find the height of the flagpole before it broke.
Since the stuck 7 m and the remaining part which is the hypotenuse together make the flagpole.
⇒ Height = 7 m + 25 m = 32 m
