Answer:

Step-by-step explanation:

Luke has a square patio, which means each side must have the same amount of tiles.

For example, he could have a 4 by 4 patio, 5 by 5, etc.

121 happens to be the square of 11. In other words, 11*11=121!

So, Luke can fit 11 tiles along each side of his patio.

Elenas aunt bought her a $150 savings bond when she was born.When elena is 20 years old,yhe bond will have earned 105% in intere

steposvetlana [31]

Answer:

$307.5.

Step-by-step explanation:

We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.

To find bond's value after 20 years we will add 105% of 150 to 150.

$\text{Bond's value after 20 years}=150+(\frac{105}{100}\times 150)$

$\text{Bond's value after 20 years}=150+(1.05\times 150)$

$\text{Bond's value after 20 years}=150+157.5$

$\text{Bond's value after 20 years}=307.5$

Therefore, the bond will be worth $307.5, when Elena will be 20 years old.

Using the Factor Theorem, which of the polynomial functions has the zeros 2, radical 3 , and negative radical 3 ? f (x) = x3 – 2

Basile [38]

Answer:

$f(x) = x^3 - 2x^2 -3x + 6$

Step-by-step explanation:

According to the Factor Theorem, if (x - k) is a factor of a polynomial P(x), then P(k) must equal zero.

We are given that a polynomial function has the zeros 2, √3, and -√3. So, we can let k = 2, √3, -√3.

So, according to the Factor Theorem, P(2), P(√3) and P(-√3) must equal 0.

Testing each choice, we can see that only A is true:

$\displaystyle f(x) = x^3 - 2x^2 - 3x + 6$

Testing all three values yields that:

$\displaystyle \begin{aligned} f(2) &= (2)^3 - 2(2)^2 -3(2) + 6 \\ &= (8) - (8) -(6) + (6) \\ &= 0\stackrel{\checkmark}{=}0 \\ \displaystyle f(\sqrt{3}) &= (\sqrt{3})^3 - 2(\sqrt{3})^2 - 3(\sqrt{3}) + 6 \\ &=(3\sqrt{3}) -(6)-(3\sqrt{3}) + 6 \\ &= 0\stackrel{\checkmark}{=}0 \\ f(-\sqrt{3}) &= (-\sqrt{3})^3 - 2(-\sqrt{3})^2 - 3(-\sqrt{3}) + 6 \\ &=(-3\sqrt{3}) -(6)+(3\sqrt{3}) + 6 \\ &= 0\stackrel{\checkmark}{=}0 \end{aligned}$

Hence, our answer is A.

Apple products such as iphones and tablets used to have maximum storage capacity of 16GB now they have a maximum capacity of 512

Naddik [55]

Answer:

3100%

Step-by-step explanation:

Calculate percentage change

from V1 = 16 to V2 = 512

(V2−V1)|V1|×100

=(512−16)|16|×100

=49616×100

=31×100

=3100%change

=3100%increase
