It is y=2x-4 (the 4th answer)
Answer:
99 yards
Step-by-step explanation:
To find the perimeter of a rectangle, the equation is perimeter = 2(width) +2(height). When we plug the known variables into this equation, it is 364 = 166 + 2(height). Now all we have to do is isolate the variable like in any algebra equation, leaving us with our final answer of 99 = height.
Answer:
23.2 cm
Step-by-step explanation:
For the angle of 53.2 deg, x is the opposite leg. The hypotenuse is 29 cm.
sin A = opp/hyp
sin 53.2 deg = x/29 cm
x = 29 cm * sin 53.2 deg
x = 23.2 cm
Answer:
Rectangular Prism - 2lw + 2lh + 2wh
Triangular prism - 2B + Ph
Pyramid - 2ll +l^2
Cylinder - 2π πrh + 2π πr^2
Cone - πrl + πr^2
Step-by-step explanation:
Y=-x^2-2x+3 a=-1, b=-2, c=3
To find the x coordinate of the vertex, we use this formula: x=b/2a
So plug everything in and you'll get x=1.
Now plug that in the original equation to find the y coordinate.
