Each cube has 6 sides. so if you're finding the perimeter it's 6+6+6+6+6+6= 36in. If area it's 6×6= 36in3
Answer:
e. 1.6π cm²
Step-by-step explanation:
Since the window is in a semi-circular shape, its area A = πD²/4 ÷ 2 = πD²/8 where D = diameter of window = 64 cm
Now, the error in the area dA = dA/dD × dD where dD = error in the diameter = 0.1 cm and dA/dD = derivative of A with respect to D.
So, dA/dD = d(πD²/8)/dD = 2 × πD/8 = πD/4
So, the differential dA = dA/dD × dD
dA = πD/4 × dD
Substituting D = 64 cm and dD = 0.1 cm into the equation, we have
dA = πD/4 × dD
dA = π × 64 cm/4 × 0.1 cm
dA = π × 16 cm × 0.1 cm
dA = π × 1.6 cm²
dA = 1.6π cm²
So, the maximum error in computing the area of the window is 1.6π cm²
Answer: 90 degrees
Step-by-step explanation: The other options are not in their neared tens only 90 degrees is.
Answer:
y = 25 - 3x
Step-by-step explanation:
x = 7 - p ⇒ p = 7 - x
y = 3(7-x) + 4
y = 21 - 3x + 4
y = 25 - 3x
Answer:
or 
Step-by-step explanation:
Subtract 29 from both sides.
There are no two integers whose sum is -4 and whose product is -38, so the trinomial is not factorable. We can use the quadratic formula.
a = 1; b = -4; c = -38
