Answers:
L = 4
M = -3

--------------------------------------

Explanation:

On the left side, the number 20-12i is in the form a+bi where a = 20 and b = -12

On the right side, 5L+(4M)i is in the form a+bi where a = 5L and b = 4M

Equating the real parts a = 20 and a = 5L has us get
5L = 20
5L/5 = 20/5
L = 4

Do the same with the imaginary parts as well
b = -12
b = 4M
4M = -12
4M/4 = -12/4
M = -3

Zarrin [17]

$\huge\text{Hey there!}$

$\mathsf{\dfrac{2^{30}}{8^9}=2x}$

$\mathsf{2^{30}}\\\mathsf{= \bf 1,073,741,824}\\\\\mathsf{8^9}\\\mathsf{= \bf 134,217,728}$

$\mathsf{\rightarrow \dfrac{1,073,741,824}{134,217,728}= 2x}\\\\\\\mathsf{\dfrac{1,073,741,824}{134,217,728}= \bf 8}\\\\\\\mathsf{\rightarrow \ 8 = 2x}\\\\\\\\\large\textsf{TURN\ the\ EQUATION\ around}\\\\\\\mathsf{\rightarrow\ 2x = 8}\\\\\\\large\textsf{DIVIDE 2 to BOTH SIDES}\\\\\\\mathsf{\dfrac{2x}{2}=\dfrac{8}{2}}\\\\\\\large\textsf{CANCEL out: }\mathsf{\dfrac{2}{2}}\large\textsf{ because it gives you 1}\\\\\\\large\textsf{KEEP: }\mathsf{\dfrac{8}{2}}\large\textsf{ because it gives you the answer of x}$

). If a, ß are zeroes of the quadratic polynomial p(x)=kx²+4x+4 such

natta225 [31]

Answer:

The values of k are 2/3 and -1

Step-by-step explanation:

Product of zeros = αβ= constant / coefficient of x^2 = 4/k

Sum of zeros =α+β = - coefficient of x / coefficient of x^2= -4/k

Given

Consider a= α and b= β

$(\alpha)^2 + (\beta)^2 = 24$

$(\alpha)^2 + (\beta)^2$ can be written as $(\alpha)^2 + 2(\alpha)(\beta) + (\beta)^2$ if we add $\pm 2 (\alpha)(\beta)$ in the above equation.

$(\alpha)^2 + 2(\alpha)(\beta) + (\beta)^2 -2(\alpha)(\beta)$

$(\alpha + \beta)^2 -2(\alpha)(\beta)$

Putting values of αβ and α+β

$(\frac {-4}{k})^2 -2( \frac {4}{k}) = 24\\\frac {16}{k^2} - \frac {8}{k} = 24\\Multiplying\,\, the \,\, equation\,\, with\,\, 8K^2\\ 2 - k= 3K^2\\3k^2-2+k=0\\or\\3k^2+k-2=0\\3k^2+3k-2k-2=0\\3k(k+1)-2(k+1)=0\\(3k-2)(k+1)=0\\3k-2=0 \,\,and\,\, k+1 =0\\k= 2/3 \,\,and\,\, k=-1$

The values of k are 2/3 and -1

The expression 1.5*1.09 models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his

Alex777 [14]

Answer: Multiplicative rate of change in housing costs, for summer term t years since Chinedu applied to his college.

Step-by-step explanation:

Given: $1.5\times1.09^t$ models the housing costs, in thousands of dollars, for summer term t years since Chinedu applied to his college.

Since, the above expression is an exponential function. [ t is the exponent ]

The standard exponential function is given by :-

$y=Ab^x$ , A is the initial amount , b is the multiplicative rate of change with respect to time period x.

as compare to the given expression, we get b= 1.09, which is the multiplicative rate of change in the housing costs, for summer term t years since Chinedu applied to his college.
