Using arc length formula find s when r=24 and θ=π/2 48π 24π 12π

bulgar [2K]

Answer:

12π

Step-by-step explanation:

The formula for arc length is given as:

$s = \frac{\theta}{360\degree} \times 2\pi r$

Plug r = 24 and θ=π/2 in the above formula, we fi d:

$s = \frac{\frac{\pi}{2}}{360\degree} \times 2\pi \times 24\\\\s = \frac{\frac{\pi}{2}}{2 \pi} \times 48\pi\\\\s = \frac{\pi}{2\times 2 \pi} \times 48\pi \\\\s = \frac{\pi}{4\pi} \times 48\pi \\\\\huge \purple {\boxed{s = 12\pi}} \\$

9x- 7i > 3 (3x-7u)
9x- 7i > 9x-21u
9x-9x-7i>21u

The image of (6, 9) under a dilation is (4, 6).

Ad libitum [116K]

For this case we have the following ordered pairs:
(6, 9)
(4, 6)
The scale factor can be found in two different ways:
$k = 6/4 = 3/2 = 1.5

k = 9/6 = 3/2 = 1.5$
Therefore, the scale factor is given by:
$k = 1.5
$
Answer:
The scale factor of the dilation is 1.5

Please help with this question, thank you

Semmy [17]

Remark
The key step is just to subtract 5 from both sides. The pointed of the inequality still points away from the variable and towards the number. As long as that remains true, the correct answer can be found.

Solution
2.7 ≤ b + 5 Subtract 5 from both sides.
2.7 - 5 ≤ b
- 2.3 ≤ b Write with the variable on the left.
b ≥ - 2.3 <<<< answer

9/10 + 7/8 in simplest form

guajiro [1.7K]

The answer is 31/40

because first you got cane both of the fraction to the same denominator.

72/80 + 70/80

Add 72+70=142.

142/80 change it to an mixed number and it will be 1 31/40 in simplest form.
