Aleksandr [31]

$\bf ~~~~~~ \stackrel{daily}{\textit{Continuously Compounding Interest Earned Amount}}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$3150.37\\
r=rate\to 4.1\%\to \frac{4.1}{100}\to &0.041\\
t=years\to &20
\end{cases}
\\\\\\
A=3150.37e^{0.041\cdot 20}\implies A=3150.37e^{0.82}\implies A\approx 7152.91457$

how much interest is there? well, A - 3150.37.

Identify the term that completes the equation. AC^2 = (DC)(?)<br><br> BC<br> AD<br> BD<br> AB

fiasKO [112]

Answer:

BC

Step-by-step explanation:

the height of a right-angled triangle to the Hypotenuse is the square root of the product of the lengths of the 2 segments of the Hypotenuse.

so the square of the height is then the product of the 2 line segments of the Hypotenuse.

therefore

AC² = DC × BC

Substitution method<br>4x + y = 14<br>6x - 3y = 3

lakkis [162]

Answer:

x = 2.5
y = 4

Step-by-step explanation:

<u>We know that:</u>

4x + y = 14
6x - 3y = 3

<u>Let's first solve for y by choosing any equation.</u>

4x + y = 14
=> y = 14 - 4x

<u>Now, let's substitute the value of y into the second equation.</u>

6x - 3y = 3
=> 6x - 3(14 - 4x) = 3
=> 6x - 42 + 12x = 3
=> 18x - 42 = 3
=> 18x = 42 + 3
=> 18x = 45
=> x = 45/18 = 5/2 = 2.5

<u>Now, let's substitute the value of x into the equation of y.</u>

=> 14 - 4x = y
=> 14 - 4(2.5) = y
=> 14 - 10 = y
=> y = 4

Hence, the value of x and y are 2.5 and 4 respectively.

Light travels about 3 x 10^5 metres per second. Find the time it takes to travel 1 metre. Give your answer in standard form.

Anna71 [15]

Answer:

t=3.3* $10^{-6}$

Step-by-step explanation:

t= $\frac{S}{v}$

As

S=1m

v=3* $10^{5}$ ms^-1

t= $\frac{1}{3*10^{5} }$

t=3.3* $10^{-6}$
