Answer:
57.1428%
Step-by-step explanation:
8 divided by 14 = 0.57142857142 then turn it to a fraction which you move the period two times to the right thus the answer is
57.1428....
i say C. -5, -2, 1, 4, 7 is your answer for question 1.
and for question 2 i think is E. -6, -4, -2, 0, 2.
The vertex is at (-3, 4)
This can be found by looking at the basic form of vertex form:
y = (x - h)^2 + k
In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = 4. This means the vertex is at (-3, 4).
The y-intercept is at 13. To find this we must first square the parenthesis and get the equation into standard form.
y = (x + 3)^2 + 4
y = x^2 + 6x + 9 + 4
y = x^2 + 6x + 13
Now we know that the y-intercept is equal to the constant, which is the last number in the equation.
Cross multiply 3x-5 with 4 and 4x + 1 with 2
Which it would give you 12x-20=8x+2 then solve for x
First work out the surface area of the solid
Area of cylindrical part:-
length of this part = 108 - 2*18 = 72 so its area
= 2 * pi * r * 72
= 2 *pi* 18 * 72 = 8143.01 cm^2
Area of the 2 hemispheres = 4 pi * 18^2 = 4071.50 cm^2
Total surface area of the solid = 12,214.51 cm^2
Cost of polishing = 12,214.51 * 7 = 85,501.58 paise
