PLEASE HELP ITS EASY!!!!!!!!!

eduard

#1 This isn't mathematics its Science

#2 I would personally say false because we can repeat a song there fore creating the same movement - vibration. Heat is also something that could be the same again. Like setting the thermostat in a home, apartment, or work place

#3 Don't hold me to #2 because I can see both sides being argued #1 is definitely right lol!

Kyle has $900 in cash received for high school graduation gifts from various relatives. He wants to invest it in a certificate

poizon [28]

Given that Kyle has received 900$ in cash as a gift and Kyle wants to invest that money in CD with 4% compound interest which is being compounded annually.

That means interest rate = 4% = $\frac{4}{100} = 0.04$ in decimals.

Since interest is compounded annually, we have to use compound interest formula.

That is amount after time t is $A= P(1+\frac{r}{n}) ^{nt}$

Where P- initial amount = 900

r= rate of interest in decimals = 0.04

n= number of times interest is compounded per year = 1

t= number of years the money is invested = 5

Hence A = $900(1+\frac{0.04}{1} )^{1*5} = 900(1.04)^{5}$

= $1094.9876

So, at the end of five year period, Kyle will have 1094.9876$ to put down in his car.

N=4; 2i and 3i are zeros <br> f(-1)=50

Nonamiya [84]

Solution:- $\text{Let f(x) be any nth degree polynomial with n=4}\\$

$\text{Given that 2i and 3i are the zeroes of f(x)}$

$\text{so (x-2i) and (x-3i) are factors of f(x)}$

$\text{Since 2i is a zero of f(x) then its conjugate -2i is also a zero of f(x)}$

$\Rightarrow(x+2i) \text{is a factor}\\\text{Similarly, conjugate of 3i is -3i is also a zero of f(x) }\\\Rightarrow(x+3i)\text{is a factor}\\\text{So , }\\f(x)=k(x-2i)(x+2i)(x-3i)(x+3i)\\=k(x^2-(2i)^2)(x^2-(3i)^2)\\=k(x^2-4i^2)(x^2-9i^2)\\=k(x^2+4)(x^2+9)\\=k(x^4+13x^2+36)\\\text{As given}\\f(-1)=50\\\Rightarrow k((-1)^4+13(-1)^2+36)=50\\\Rightarrow k(1+13+36)=50\\\Rightarrow k(50)=50\\\Rightarrow k=1\\\text{So by substituting k=1 in f(x) we get ,}\\f(x)=(x^4+13x^2+36)$
