Answer:

the radius is 3.5 cm

the Diameter is 7 cm

The answer would be 14 cm.

The formula to find diameter is d=2r
D= diameter
R= radius
The 2 is there because you have half of the diameter so just times by 2 to get the diameter.

Divide 6.391 ÷ 0.57. Round the quotient to the nearest hundredth.
Paul [167]
The answer is 11.21, dividing 6.391 by 0.57 will give you 11.2122807018.
Rounding to 11.21 because the thousandths place is less then 5 so the hundredths place stays the same.

Which translation maps the vertex of the graph of the function f(x) = x2 onto the vertex of the function g(x) = x2 + 2x +1?
raketka [301]
While the vertex of the function f(x) = x^2 is (0, 0), the vertex of the function g(x) = x^2 + 2x + 1 is (-1, 0).
Whereas both function has same y-cordinate, their x-coordinate are different which indicates that the function g(x) = x^2 + 2x + 1 is a horizontal translation of the function f(x) = x^2.

PLEASE HELP ME OLEASE UT URGENT !
Ket [755]
Answer:

Explanation:

m = (y1 - y)/(x1 - x)

y1 = 50, y = 90
x1 = 2, x = 4

m = (50 - 90)/(2 - 4)
m = -40/-2
m = 20

b is the y intercept = 50

So our equation is written as:

y = 20x + 50

Which functions graph is a translation of the graph of f(x)= 3x^2 + 4 seven units down?
asambeis [7]

Answer:

Option C

Step-by-step explanation:

Consider the function f ( x ) = 3x^2 + 4;

f ( x ) = 3x^2 + 4,\\\\4 = vertex ( y - intercept ),\\\\\\

Now if this graph were to be translated 7 units down, considering the function was f ( x ) = 3x^2, the new graph would be f ( x ) = 3x^2 - 7. The same concept is applied to the graph f ( x ) = 3x^2 + 4;

4 - 7 = - 3,\\f ( x ) = 3x^2 - 3\\\\Solution - Option C

* Note that a translation doesn't effect the rate with which the graph changes, it only effect's it's position on the coordinate plane

<em>Hope that helps!</em>
