Answer: 530 cm^2
Step-by-step explanation:
A = 3.14 * r^2
A = 3.14 * 13 * 13
A = 3.14 * 169
A = 530 cm ^2
Answer:
Very little information is given, leaving room to multiple possible functions, however i would expect it to be y = 4x
Step-by-step explanation:
x * z = y
4 * z = 16
z = 16/4
z = 4
The slope can sometimes be called the gradient, and the equation for the gradient is (y2 - y1)/(x2 - x1). So therefore, you'd do: (-8 - 7)/(4 - -5) which is (-15)/9) which is -1 2/3 or -1.6 (recurring), which is your answer. I hope this helps! Let me know if I've confused you :)
Answer:
Step-by-step explanation:
let the number is x
3x+4=-8
3x=-8-4
3x=-12
x=-4
