The function
f left parenthesis x right parenthesis equals 25 left parenthesis 0.965 right parenthesis superscript xf(x)=25(0.965)x
models the percentage of surface sunlight, f(x), that reaches a depth of x feet beneath the surface of the ocean. the figure shows the graph of this function. use the function to determine at what depth, to the nearest foot, there is 1% of surface sunlight. how is this shown on the graph of f?
0183654729003691215depthintensity a coordinate system has a horizontal axis labeled depth from 0 to 90 in increments of 9 and a vertical axis labeled intensity from 0 to 15 in increments of 1.5. from left to right, a curve starts at the point (20, 12) and falls at a decreasing rate to the point (90, 1). all coordinates are approximate.
at what depth is there only 1% of surface sunlight?
nothing
feet
(do not round until the final answer. then round to the nearest whole number as needed.)
what point on the graph represents this?
nothing
(type an ordered pair. round to the nearest whole number as needed.)

A2.00-m long piano wire with a mass per unit length of 12.0 g/m is under a tension of 8.00 kn. what is the frequency of the fundamental mode of vibration of this wire?

The star betelgeuse is about 600 light-years away. if it explodes tonight, a. we'll know because debris from the explosion will rain down on us from space.b. we'll know it immediately because it will be brighter than the full moon in the sky.c. we won't know about it until 600 years from now.d. none of the above.
