Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = 
= 
( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = 
= 
= 
( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = 
≈ 3.7 m ( to 1 dec. place )
Answer:
y = -4x + 5
Step-by-step explanation:
This linear function can be represented through the slope-intercept form, or y=mx+b. You already know your m value, 4, which is your slope. From there you can plug in your coordinate into the y and x values to find your y-intercept, or b.
y = mx + b
-3 = -4(2) + b
b = 5
Then you put it all together to form the equation f(x) = -4x + 5
Answer:
4024
Step-by-step explanation:
the percentage of 8/13 is 61.5 percent leaving 5/13 to be 38.5 percent
and 38.5 percent of 10452 is 4024
