Answer:
Step-by-step explanation:
From the given right angle triangle,
the hypotenuse of the right angle triangle is 25
With ∠ 31 degrees as the reference angle,
the adjacent side of the right angle triangle is the unknown side.
the opposite side of the right angle triangle is x.
To determine x, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 31 = x/25
x = 25Sin31
x = 25 × 0.5150
x = 12.875
Answer:
Step-by-step explanation:
Rewrite this quadratic in standard form: 3x^2 + 7x - 1.
The coefficients of x are {3, 7, -1}, and so the discriminant is b^2 - 4ac, or
7^2 - 4(3)(-1), or 49 + 12, or 61. Because the discriminant is positive, this quadratic has two real, unequal roots
2b < 10
b < 5
How to draw it:
1. Draw a hollow point on number "5"
2. Draw a small vertical line on the top of the point.
3. Draw a long honrizontal line from that vertical line to the left to the end, and add an arrow.
(-4,-3) (-2,3)
3-(-3) = 6
-2-(-4)= 6
m = 6/6 or 1
y=mx+b
3=1(-2)+b
3=-2+b
5=b
y = x + 5
