Answer:
<em>x = 12</em>
Solve for x:
<em>Using Pythagorean Theorem </em>
a^2 + b^2 = c^2
a = 9
c = 15
b = x
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 144 | sqrt
x = 12
Volume of a sphere is 4/3(pi r ^3)
You were given d = 10 so r = 5
Then just plug and chug
3 years
ar(n)=total a is the first number which is 7000 r is the common ratio which is 100%+2%=102 102 divided by 100 giving u 1.02(interest) so ar(n)=sum n is written as power.....and is the number of years so 7000*1.02(n)=(7000+420) 1.02(n)=7420/7000 1.02(n)=1.06 log10 1.02(n)=log10(1.06) ( multiply log10 with both) n=log10(1.06)/log10 (1.02) u get 2.94 which is round off to 3 so 3 years.. hope This helps :)
Use area formula (length x width)
42 x 25.5 = 1,071
Divide by total cost of wall paper
1,071/771.25 = $1.38 per square foot
Answer:
Step-by-step explanation:
Work backwards with synthetic division with remainder 0 and then solve for a:
-3 | 2 a 19 3
_________
2 | 0
-3 | 2 a 19 3
_______<u> -3</u>
2 | 0
-3 | 2 a 19 3
_______<u> -3</u>
2 1 | 0
-3 | 2 a 19 3
_____<u>-18 -3</u>
2 1 | 0
-3 | 2 a 19 3
_____<u> -18 -3</u>
2 6 1 | 0
-3 | 2 a 19 3
_____<u> -18 -3</u>
2 6 1 | 0
-3 | 2 a 19 3
____<u>-6 -18 -3</u>
2 6 1 | 0
a - 6 = 6
a = 12
