Answer:

$\textsf{A)} \quad 5u^3-2u^2+5u+8$

Step-by-step explanation:

Given expression:

$(-2u^3+5u-1)+(7u^3-2u^2+9)$

Remove parentheses:

$\implies -2u^3+5u-1+7u^3-2u^2+9$

Collect like terms:

$\implies -2u^3+7u^3-2u^2+5u-1+9$

Combine like terms:

$\implies 5u^3-2u^2+5u+8$

Is 3.222222 a rational number

SIZIF [17.4K]

Answer:

Step-by-step explanation:

If the number is rational, I can write it as a fraction in which the numerator and denominator are integers (denominator other than 0).

$3.\underbrace{222222}_{6}=\dfrac{3222222}{1\underbrace{000000}_6}-\bold{RATIONAL}$

If is repeating:

$x=3.2222....$ <em>multiply both sides by 10</em>

$10x=32.2222...$ <em> make the difference 10x - x</em>

$10x-x=32.2222...-3.2222...$

$9x=29$ <em>divide both sides by 9</em>

$x=\dfrac{29}{9}-\bold{RATIONAL}$

Which logarithmic equation is equivalent to the exponential equation below?

aleksandr82 [10.1K]

Option B: $\ln 6=5 x$ is the correct answer.

Explanation:

The exponential equation is $e^{5 x}=6$

If $f(x)=g(x)$ , then $\ln (f(x))=\ln (g(x))$

Thus, the equation becomes

$\ln \left(e^{5 x}\right)=\ln (6)$

Applying log rule, $\log _{a}\left(x^{b}\right)=b \cdot \log _{a}(x)$ and thus the equation becomes

$5 x \ln (e)=\ln (6)$

Since, we know that, $\ln (e)=1$ , using this we get,

$5 x=\ln (6)$

Hence, the logarithmic equation which is equivalent to the exponential equation $e^{5 x}=6$ is $\ln 6=5 x$

Thus, Option B is the correct answer.

Cylinder capacity 4.25 L, cylinder diameter of 13 what is the height of the cylinder?

Musya8 [376]

Answer:

Step-by-step explanation:

Capacity of cylinder =4.25L

So volume of the cylinder=4250

πr^2h=4250

3.14×6.5×6.5×h=4250

132.665h=4250

h=4250/132.665

h=32.035
