Answer: 169.2cm
Step-by-step explanation:
From the question, we are informed that three equal-sized cardboard boxes are stacked on top of each other and that each box is 56.4 cm in height.
To get the combined height of the 3 stacked boxes, we multiply 56.4cm by 3. This will be:
= 56.4cm × 3
= 169.2cm

Step-by-step explanation:
(-4,-3)(4,1)......slope formula : (y2 - y1) / (x2 - x1)
slope = (1 - (-3) / (4 - (-4) = (1 + 3) / (4 + 4) = 4/8 = 1/2
A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of slope 1/2, we flip the slope and change the sign.
So our perpendicular line will have a slope of -2/1 or just -2 (see how I flipped 1/2, making it 2/1, and then changed the sign, making it -2/1..or just -2)
y - y1 = m(x - x1)
slope(m) = -2
(-4,3)....x1 = -4 and y1 = 3
now we sub
y - 3 = -2(x - (-4) =
y - 3 = -2(x + 4) <=== ur perpendicular line
Answer:
x = 2
Step-by-step explanation:
Using the rules of logarithms
• log ⇔ nlog x
• log x + log y ⇔ log(xy)
• log x = log y ⇒ x = y
Given
3 ln2 + ln8 = 2ln(4x)
ln2³ + ln8 = ln(4x)²
ln8 + ln8 = ln16x²
ln(8 × 8) = ln16x²
ln64 = ln16x², hence
16x² = 64 ( divide both sides by 16 )
x² = 4 ( take the square root of both sides )
x = = 2
