WILL MARK BRAINLIEST In a scavenger hunt through the city, Item 1 lies due north of Item 2. Item 3 lies due east of Item 2. Which equation
can be used to find the distance from Item 1 to Item 3?
Item 1
x mi
1.5 mi
A. 1.5 + 4 = x
B. 1.52 + 42 = x2
C. x2 + 42 = 1.52
D. 1.52 + x2 = 42
Item 2
4 mi
Item 3

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

The multiplicative property of equality states that for real numbers a, b, c, and d, if a = b and c = d, then ac = bd. true false

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.
