Answer:
Step-by-step explanation:
The cube root is 16. Often times, teachers just let you use calculators on these questions.
Simple interest rate for one year = 1.5%
simple interest rate over 5 years = 1.5 x 5 = 7.5%
100% + 7.5% = 107.5%
107.5% = $19500
1% = 181.3953
100% = $18140.50
He needs to put in $18140.50 so that he can get $19,500 at the end of 5 years.
1/2a - 4
Add 4 to both sides.
1/2a = 4
Divide both sides by 1/2.
a = 8
Answer:

Step-by-step explanation:
It is given that circle is a tangent to y axis, which tells us that the distance between the centre point and y axis is the radius of the triangle.
Formula for equation of circle with centre (x1,y1) and radius r is

In the given case distance between the centre and y axis is 7 units so radius would be 7 and the centre point is (-7,2),
the equation of circle is ,


Hence the abow equation is the circle equation.
