Answer:
426, 800

Explanation:
When you round 8 you get 10
That will then add to 4 (40) and it will get you 5 (50)
5 (50) will then round to 10 (100) which will add t. The 7 (700)
That will get you the answer 426, 800

Find the samllest value of K when :<br> 280k is a perfect square<br> 882 is a cube
adoni [48]
280 = 7 x 2^3 x 5
882 = 7^2 x 2 x 3^2

For 280k to be perfect square , their powers need to be even
For 882 to be a cube, their powers need to be in multiple of 3,

To satisfy both parties,
K = 7 x 2^5 x 3^4 x 5^3 = 2268000

Which series of transformations results in the image being congruent to the pre-image?
erik [133]
For the element to be congruent only rotations, reflections or translations are allowed to be applied
1)
(x, y) → (x, –y)=reflection
(x, y) → (x + 5, y)=translation
(x, y) → (–x, y)=reflection
->is congruent
2)
(x, y) → (x + 1, y)=translation
(x, y) → (–x, –y)=reflection
(x, y) → (2x, y)=scaling->can't be congruent
3)
(x, y) → (0.5x, 0.5y)=scaling->can't be congruent
(x, y) → (x, –y)
(x, y) → (x, y + 8)
4)
(x, y) → (x – 4, y)=translation
(x, y) → (x, y + 3)=translation
(x, y) → (3x, 3y)=scaling->can't be congruent

so 1) is the only series of transformations with a congruent solution

You are planning to invest $500 at 12% compounded annually. How much money would you have after 10 , 20 and 30 years?
Serjik [45]

A=P(1+r)^t

where A=final amount

P=principal

r=rate in decimal form

t=time in years


we are given that P=500, r=12%=0.12

we want to find A when t=10, 20, and 30


so

A=500(1+0.12)^t

A=500(1.12)^t

when t=10, A=500(1.12)^{10}=$1552.92

when t=20, A=500(1.12)^{20}=$4823.15

when t=30, A=500(1.12)^{30}=$14980.96

a rectangle has a height of n3+4n2+3n and a width of n^3+5n^2 express the area of the entire rectangle
alukav5142 [94]

<u>Given</u>:

It is given that the height of the rectangle is n^3+4n^2+3n

The width of the rectangle is n^3+5n^2

We need to determine the area of the entire rectangle.

<u>Area of the rectangle:</u>

The area of the rectangle can be determined using the formula,

A=height \times width

Substituting the values, we have;

A=(n^3+4n^2+3n)(n^3+5n^2)

Multiplying each term within the parenthesis, we get;

A=n^{3} n^{3}+n^{3} \cdot 5 n^{2}+4 n^{2} n^{3}+4 n^{2} \cdot 5 n^{2}+3 n n^{3}+3 n \cdot 5 n^{2}

Simplifying, we get;

A=n^{6}+5 n^{5}+4n^{5}+20 n^{4}+3  n^{4}+15 n^{3}

Adding the like terms, we have;

A=n^{6}+9n^{5}+23 n^{4}+15 n^{3}

Thus, the area of the entire rectangle is n^{6}+9 n^{5}+23 n^{4}+15 n^{3}
