Answer:

As given Point A is the center of the circle.

We will answer this question by considering all the options.

Option 1. FA : AE [ Both FA and EA are radius of circle .So their ratio can't be equal to 1:2.]

Option 2. CB : FE [ CB is a chord and FE is a Diameter as length of Chord not given, So we can't Predict about their Ratio.]

Option 3: FE : AH [As FE is the Diameter and AH is radius.Diameter = 2 × Radius,So FE : AH=2:1]

Option 4 : AH : FE [Explained above AH: FE=1:2]

Option 5: AH : AD [AH is the radius of the circle and D is any point on AH So their ratio can't be 1:2.]

Option (d) AH : FE = Radius : Diameter=1:2 is true.

I would go with D) AH:EF. The easiest relationship among the parts of a circle that would have the ratio of 1:2 would be that of a radius to a diameter. Among the choices, the one that matches the 1:2 ratio would be AH (a radius) and EF (a diameter).

A sign painter paints individual numerals for a row of 50 houses. The houses are numbered with consecutive integers from 1 to 50

Iteru [2.4K]

Answer: 5

List out the numbers from 1 to 50. Then go through that list and circle any numbers that have 9 in them. Those numbers are:
9, 19, 29, 39, 49
So there are 5 houses with 9s painted

The area of a round table is 1.13 m2. Find the radius length of

hichkok12 [17]

Answer:

0.6 m

Step-by-step explanation:

-The area of a circular shape is given by the formula:

$A=\pi r^2\\\\\#Where\\r-Radius\\A-Area$

We substitute the given value of area in the formula to solve for Radius:

$A=\pi r^2\\\\1.13=\pi r^2\\\\r=\sqrt{\frac{1.13}{\pi}}\\\\=0.59974\approx0.6\ m$

Hence , the radius length of the table is 0.6 m

In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) = x2 to the number of x-intercepts in

TEA [102]

F(x) has only one x-intercept when x=0

g(x)=-x^2-6

g(x)=-(x^2+6) so g(x) will have no x-intercepts as its maximum value will be -6.

g(x) is f(x) reflected about the x axis and shifted downwards by 6 units.

action bar. John has $132.55 in his bank account. He wants to join a guitar class that charges a $15 fee every week. John plans

Artemon [7]

$132.55-($15*12)=$132.55-$180=$-47.45
So then he would have owed 47.45 dollars!
