Show the work to divide 8.4 by 0.03

2 answers:

8 0

0.03 sqrt 8.4
You would need to make 0.03 a whole number, first. Then take the decimal point, and move it two places, and do the same for 8.4.
3 sqrt 840
Now divide the way you usually would. If there is a remainder, keep adding zeros until you get the answer without a remainder. If the zeros keep going on and on, then just stop after two zeros.

Well, 0.03= 3%
So i divided 8.4 by 100 and i got 0.084.
Then I multiplied that by 3 (because 3%) and i got the answer of 0.252

Put the equation in standard linear form.

$x'(t) + \dfrac{x(t)}{t + 5} = 5e^{5t}$

Find the integrating factor.

$\mu = \exp\left(\displaystyle \int \frac{dt}{t+5}\right) = e^{\ln|t+5|} = t+5$

Multiply both sides by $\mu$ .

$(t+5) x'(t) + x(t) = 5(t+5)e^{5t}$

Now the left side the derivative of a product,

$\bigg((t+5) x(t)\bigg)' = 5(t+5)e^{5t}$

Integrate both sides.

$(t+5) x(t) = \displaystyle 5 \int (t+5) e^{5t} \, dt$

On the right side, integrate by parts.

$(t+5) x(t) = \dfrac15 (5t+24) e^{5t} + C$

Solve for $x(t)$ .

$\boxed{x(t) = \dfrac{5t+24}{5t+25} e^{5t} + \dfrac C{t+5}}$

6.746913 rounded to the nearest tenths place

Minchanka [31]

Answer:

6.7

Step-by-step explanation:

Rounding decimals is very similar to rounding other numbers. If the hundredths and thousandths places of a decimal is forty-nine or less, they are dropped and the tenths place does not change.

For example, rounding 0.843 to the nearest tenth would give 0.8.

77th term for -10,-8,-6

sasho [114]

9514 1404 393

Answer:

142

Step-by-step explanation:

The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...

an = a1 +d(n -1)

an = -10 +2(n -1) = 2n -12

Then the 77th term is ...

a77 = 2(77) -12 = 154 -12

a77 = 142

The 77th term is 142.

Describe how you can use the information in a table showing a linear relationship to find the slope and y-intercept for the equa

maks197457 [2]

If you have a table that tells you the (x,y) or coordinates on a graph you can take those coordinates and insert them into the equation y=mx=b. this is the equation to find the slope of a line. If you solve for b in the equation you will have the y intercept. the mx would be the slope.
