D = 144 - 16t^2
144 - 16t^2 ≥ 0
16(9 - t^2) ≥ 0
9 - t^2 ≥ 0
9 ≥ t^2
t ≥ + or -3

Required interval is 0 ≤ t < 3

Round 27346 to 2 significant figures i need a step by step expansion
belka [17]

Answer:

27000

Step-by-step explanation:

We want to round 27346 to 2 significant figures.

Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.

Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.

Order the equations from least to greatest based on the number of solutions to each equation.
aleksandrvk [35]

In order it  goes like this

- 4^ x - 1 = 3^ (-x) - 2

- 3 x + 6 = 2^ x + 1

3^ x - 3 = 2 x - 2

so the question is the answer

aliina [53]

Step-by-step explanation:

they forget the last step which is to take the square root of the sum

7) a = 4

b = 17

a² + b² = c²

4²+ 17² = c²

16 + 289 = c²

305 = c²

√305 = c

17.464249196572980 = C
