Cos35= y/15
y= 15cos35
y= 12.3 cm
The reflection of any point across the x axis is the symmetric of this point, having x axis as axe of symmetry
Let :
A(1,3) its symmetric vs. x axis is A'(1,-3)
B(-1,5) its symmetric vs. x axis is B'(-1,-5)
C(-3,-3) its symmetric vs. x axis is C'(-3,3)
D(-4,-4) its symmetric vs. x axis is D'(-4,4)
Symmetry vs. the x axis keeps abscises the same & change just the sign of y value

The true statements are that the diameter is 5 in, the base area is 19.63 in², the volume is 58.88in³ and the cost is $14.72.
Since the radius is 2.5 in, the diameter is 2*2.5 = 5.
The base is a circle. Therefore the base area is found by the formula
A=πr²=(3.14)(2.5)²=19.625≈19.63in².
The volume of a cone is given by multiplying the base area by the height and then taking 1/3 of it:
19.625(9)/3 = 58.875≈58.88in³.
The cost would be 58.88*0.25 = $14.72.
Answer:
1/2
Step-by-step explanation:
1/2 times 1/2 equals .25 (.25 is 1/4 which is half of 1/2)
1/2 divided by 1/2 is 1( 1 is 1/2 plus 1/2)
