Im Not Sure But Im Thinking 7/10 Wrote As in A Fraction .
Replace x in the equation with 3.5 and do the arithmetic.
y = 1.3*3.5 -0.52
y = 4.55 -0.52
y = 4.03
The predicted approximate value of y is 4.03.
Answer:
So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.
Examples:
If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.
So the answer to 4 with an exponent of -2 would be .0016.
Answer:
242.76m^2
Step-by-step explanation:
Given data
Height=18m
Volume=4,374m^3
We know that the expression for the volume of a cylinder is
V=πr^2h
substitute
4374=3.142*r^2*18
4374=56.556*r^2
4374/56.556=r^2
77.339=r^2
r=√77.339
r= 8.79m
But the area of a circle is expressed as
A= πr^2
A=3.142*8.79^2
A=3.142*77.2641
A=242.76m^2
Hence the area of the base is 242.76m^2
