z2=22.09
(1 point)
The smaller answer is
.
The larger answer is
.
Taking the square root of both sides of the equation, we get:
z = ±√22.09
Using a calculator, we find that √22.09 ≈ 4.7
Therefore, the smaller answer is -4.7 and the larger answer is 4.7.
To solve the equation z^2 = 22.09, we need to take the square root of both sides.
Taking the square root of both sides, we get:
z = ±√22.09
Simplifying the square root of 22.09, we find:
z ≈ ±4.7
Round to the nearest tenth, the smaller answer is approximately -4.7 and the larger answer is approximately 4.7.
To find the values of z, you can take the square root of both sides of the equation z^2 = 22.09.
The square root of 22.09 is approximately 4.7. So the smaller answer is -4.7.
The negative value is included because when you square a negative number, it becomes positive.
The larger answer is 4.7.
Rounding both answers to the nearest tenth, we get:
The smaller answer is -4.7.
The larger answer is 4.7.
