Answer:

Circle is a plane region bounded by by a line that lies at a uniform distance from a fixed point.

Step-by-step explanation:

Circle is a plane figure which is formed by the locus of a point which is at a fixed distance from a fixed point called center and the periphery of the figure is called circumference. The distance between any point on the periphery and the center is called radius of the circle.

Diameter is twice the length of the radius and it is the largest line segment that can be drawn between any two points on the circumference.

Any line segment connecting any two points on the periphery of the circle is called a chord, diameter is the largest chord.

Any line passing through any two points on the circumference of a circle is called a secant.

Any line passing through any one point on the circumference of a circle is called a tangent.

12% of birr x is 840,what is the value of x​
Diano4ka-milaya [45]

The value of x will be 7000 for the expression 12 % x = 840.

We are given a number x.

We are also given as 12 % of x is 840

writing it in the form of an expression, we get that:

12 % x = 840

12 / 100 × x = 840

12 x = 84,000

Dividing both sides by 12, we get that:

12 x / 12 = 84,000 / 12

x = 7000

Therefore, the value of x will be 7000.

A couple needs $55,000 as a down payment for a home. If they invest the $40,000 they have at 4% compounded quarterly, how long w
slava [35]

Answer:

8 years

Step-by-step explanation:

Compound interest formula

A(t)= A_0(1+\frac{r}{n})^{nt}

A(t) is the final amount 55000

A_0= 40000, r= 4% = 0.04, for quarterly n=4

55000=40000(1+\frac{0.04}{4})^{4t}

divide both sides by 40000

1375=(1+\frac{0.04}{4})^{4t}

1375=(1.01)^{4t}

Take ln on both sides

ln(1375)=4tln(1.01)

divide both sides by ln(1.01)

\frac{ln 1375}{ln 1.01}=4t

Divide both sides by 4

t=8.00108

So it takes 8 years
