If sinα=1/4 and it is in q2 it means that the x coordinate is negative.
The triangle has a height of one and a hypotenuse of 4 so:
x=-√(4^2-1)
x=-√15
so tanα=-1/√15
tanα=-√(1/15)
tanα≈ -0.258
Answer:
Slope = 2/3
intercept= 1/3
Step-by-step explanation:
The standard form of equation of a line in slope intercept form is expressed as;
y = mx+b
m is the slope
b is the y-intercept
Given the expression
y-3=2/3(x-4)
Cross multiply
3(y-3)=2(x-4)
Expand
3y - 9 = 2x - 8
3y - 2x = -8 + 9
3y - 2x = 1
3y = 2x+1
Divide through by 4
y = 2/3 x + 1/3
Comparing
mx = 2/3 x
m = 2/3
b = 1/3
Hence the slope of the function is 2/3 and the intercept is 1/3
Whatever was being measured is lower for the second year than it was for the first.
Answer:
(2,2)
Step-by-step explanation:
The slope is -2 so going from the point (1,4), the point would be (2,2)
The zeroes of the polynomial are the values of x that will make the f(x) = 0.
0 = x^2 + x - 6
Use factoring,
0 = (x + 3) (x - 2)
x + 3 = 0 and x - 2 = 0
Thus, the values of x are <em>x = -3</em> and <em>x = 2</em>.
