The answer is B. Use the trig identity (sin x)^2+(cos x)^2=1. Since cos x=0.3090, sinx=+-\sqrt(1^2-0.3090^2)=+-0.9511. Since 0<x<90, sin x must be positive, so sin x=0.9511. tan x=sin x/cos x=0.9511/0.3090=3.0780.
Answer:
y = 8x + 8
Step-by-step explanation:
The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8
Answer:
looks like 1 from the graph.
Answer:
D) ![-\sqrt[3]{x-1}](https://tex.z-dn.net/?f=-%5Csqrt%5B3%5D%7Bx-1%7D)
Step-by-step explanation:
-the function is the cube root
-the cube root of zero is zero
- the graph is at 0 when x = 1, thus "x-1" must be part of answer
- the cube root of -8 is -2, at -8 the graph is +2. so the function is negated
