Answer:
y=3x^2-6x+3
Step-by-step explanation:
9 square units.
the area of a triangle is 1/2 base x height.
the base of this triangle is the line RS which is 6 units long, and the height is the dashed line, which is 3 units long. 1/2 x 6 x 3 = 9
Answer:
-1
Step-by-step explanation:
Complete the square to find the vertex of this parabola y^2-8x+2y+17=0 {The second answer is -1; so 2,-1 }
Answer: -13.9
This value is approximate.
==================================================
Explanation:
This angle is in quadrant Q2, which is where x is negative and y is positive.
The angle shown of 65 degrees is added to the 90 degree angle to the right resulting in 65+90 = 155 degrees overall. See diagram below.
The x component of the vector is found by the formula
x = r*cos(theta)
we will plug in r = 15.3 as the magnitude of the vector and theta = 155 as the angle
x = 15.3*cos(155)
x = -13.8665 approximately
x = -13.9 rounding to one decimal place (as 15.3 and 65.0 are both rounded to one decimal place)
