Hey there!
Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.
Alright, I'll give you four of those:
- 121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121
- 484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 484
- 10201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 10201
- 12321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321
Hope this helps!
Y = kx is the direct variation equation, where 'k' is the constant of variation.
12 = 7(x)
Divide both sides by 7
12/7 = x
Answer:
The last choice.
Step-by-step explanation:
The last term is - 20 and because we have a coefficient of 1 on the x^3, and in order to get this last term and the given roots the factors have to be
(x + 5)(x + 4)(x - 1) so it is the last option.
Answer:
The correct answer is $3300 for simple interest and $3312.24 for compound interest.
Step-by-step explanation:
Income as working as a lifeguard = $3000
We deposit the money in a bank which offers 2% interest annually for a period of 5 years.
Case 1 : Calculating simple interest for the given situation.
Amount after 5 years = 3000 + 3000 × 2 × 5 × 
= $ ( 3000 + 300) = $3300.
Case 2 : Calculating compound interest for the given situation.
Amount after 5 years = 3000 × 
= $ 3312.24.
Thus the amount after 5 years amount simply is $3000 and compoundly is $3312.24
Answer:
The largest possible area is 10,000 square feet
Step-by-step explanation:
Since she has 400 ft of fencing material, this means that the perimeter of the pen will be 400 ft
Mathematically, the perimeter of a rectangle is is;
2(l + b) = 400
Thus, l + b = 400/2
l + b =200
This means the length and width pen add up to 200
Mathematically, the maximum area can be obtained if the side of the length and the width are equal
So we will have to share the 200 into 2 , that makes 100 for each
The largest possible area is thus;
100 ft * 100 ft = 10,000 square feet
