Answer:
15 cm
Step-by-step explanation:
The altitude is one leg of the right triangle formed by the altitude, half the base, and the triangle side. The Pythagorean theorem applies, so you have ...
... (17 cm)² = (altitude)² + (16 cm/2)²
... altitude = √(17² -8²) cm = √225 cm
... altitude = 15 cm
At h=1 y=-2 so -2 hope it helps!
The numbers inside the parenthesis is the value of x, uses the equation associated with the value of x and solve.
H(1) Since 1 fits 1≤x≤3 use x^3
x^3 1^3 = 1
h(1) = 1
h(4) 4 fits x >3, so use 5
h(4) = 5
Answer: 4r^2
Step-by-step explanation:
Area of the bottom triangle = 1/2 x 10 x 8.7 = 43.5 cm²
Area of the 3 rectangles = 3(10 x 6) = 180 cm²
Area of the top triangle = 3 (1/2 x10 x 4) = 60 cm²
Total surface are = 43.5 + 180 + 60 = 283.5 cm²
Answer: 283.5 cm²
