Step-by-step explanation:
Answer:
91.1 cubic inches to 1 dp
Step-by-step explanation:
4.5 X 4.5 X 4.5 = 91.125 cubic inches
or
4.5^3 = 91.125 cubic inches
Use I=PRT/100 to solve the question
Answer:
A.0
Step-by-step explanation:
y=4x²- 9x + 9
The function will intersect the x-axis when y = 0.
4x² - 9x + 9 = 0
a=4, b= -9, c=9
D=b² - 4ac = (-9)²- 4*4*9=81 - 144= - 63
D= -63, D<0, so the equation
4x² - 9x + 9 = 0 does not have real roots. That means that function y=4x²- 9x + 9 does not intersect x- axis. So, answer is A. 0.
