If t₀ is the initial temperature of the metal then after time t hours the temperature will be t₀-5t, which must not go below -75℃.
So t₀-5t≥-75.
A) 3, 5, 6
c squared = a squared + b squared
6 squared = 5 squared + 3 squared
36 = 25 + 9
36 ≠ 34 (not a right triangle)
b) 13, 12, 5
c squared = a squared + b squared
13 squared = 12 squared + 5 squared
169 = 144 + 25
169 = 169 (is a right triangle)
c) 17, 15, 9
c squared = a squared + b squared
17 squared = 15 squared + 9 squared
289 = 225 + 81
289 ≠ 306 (not a right triangle)
d) 12, 8, 6
c squared = a squared + b squared
12 squared = 8 squared + 6 squared
144 = 64 + 36
144 ≠ 100 (not a right triangle)
hope this helps!!
Answer: 918 is the constant of variation.
Step-by-step explanation:
Since, In see saw the weight (w) of an object is inversely proportional to the distance (d) from the seesaw support.
That is w ∝ 1/d
or w = k/d
where k is the constant of variation.
Here, The weight of Levon, w = 153 lb
And, his distance from the see saw support, d = 6 ft
Therefore. 153 = k/6
⇒k= 153 × 6 = 918
I can answer this whats obtaining number the common difference and first number?
1/2 which is equal to 0.5 x 2,000 is 1,000
