Answer:
Expressions with fractional or negative exponents can be factored by pulling out a GCF. Look for the variable or exponent that is common to each term of the expression and pull out that variable or exponent raised to the lowest power. These expressions follow the same factoring rules as those with integer exponents.
Step-by-step explanation:
Answer:
The volume is 140 cm3. See the explanation below, please
Step-by-step explanation:
We use the formula:
Volume (V) = 4/3 pi r ^3
V= 4/3x 3, 14x (6,44/2)^3 = 139,8 cm3= 140 cm3
Answer:
t=-7u+70/0
Step-by-step explanation:
Cos <span>θ = 0.5333
inverse cosine both sides of equation
cos⁻¹(cos </span>θ) = cos⁻¹(0.5333)
on left side, cosine cancel out
on right side use calculator in radian mode
θ = 1.0083
for the ttriangle, assuming c is the hypotenuse
pythagoras
a² + b² = c²
b² = c² - a²
b = √(c² - a²)
b = √(9² - 2²)
b = 8.77
Try to solve with all the options,
B is the right answer.
