Answer:

x = 5

Step-by-step explanation:

Solve for x.

$6 - 6x = 4x - 44$

Subtract 6 from BOTH sides

$6 - 6 = 4x - 44 - 6$

Simplify.

$-6x = 4x - 50$

Subtract 4x from BOTH sides.

$-6x - 4x = 4x - 50 - 4x$

Simplify again.

$-10x = -50$

Divide BOTH sides by -10.

$\frac{-10x}{-10} = \frac{-50}{-10}$

Simplify once more...

$x=5$

Solve for b pythagorean theorem! someone plz help meeeee

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Since we already know c, so we need to find b.

c² = a² + b²

5² = 4² + b²

b² = 5² - 4²

b² = 25 - 16

b² = 9

b = 3

If Free Yer Assets Bank (FYAB) will give you 0.25% compounded quarterly and I.M.A.Q.T.π bank will give you 0.23% interest compou

ivann1987 [24]

Answer:

FYAB gives a better deal.

Step-by-step explanation:

Compound interest:

$A = P(1 + \dfrac{r}{n})^{nt}$

Continuously compounded interest:

$A = Pe^{rt}$

For the quarterly compounded interest, r = 0.25%, and n = 4.

$2P = P(1 + \dfrac{0.0025}{4})^{4t}$

$1.000625^{4t} = 2$

$\log (1.000625^{4t}) = \log 2$

$4t(\log 1.000625) = \log 2$

$t = \dfrac{\log 2}{4\log 1.000625}$

$t = 277$

For the continuously compounded interest, r =0.23%

$A = Pe^{rt}$

$2P = Pe^{0.0023t}$

$2 = e^{0.0023t}$

$\ln 2 = \ln e^{0.0023t}$

$\ln 2 = 0.0023t$

$t = \dfrac {\ln 2}{0.0023}$

$t = 301$

The quarterly compounded doubles in 277 years.

The continuously compounded doubles in 301 years.

Answer: FYAB gives a better deal.

Express the following in exponential notation:<br> (-13) X (-13).<br> 35 times

miv72 [106K]

Answer:

$(-13) * (-13) = (-13)^{2}$

$35 * 35 = 35^{2}$

Step-by-step explanation:

Given

$(-13) * (-13)$

Required

Express as an exponential notation

$(-13) * (-13)$

Apply the following law of indices

$x^a * x^b = x^{a+b}$

This gives:

$(-13) * (-13) = (-13)^{1+1}$

$(-13) * (-13) = (-13)^{2}$

<em>The second complete is incomplete; However, I'll assume it is: 35 times 35</em>

$35 * 35$

Using the same law applied in (1) above:

$35 * 35 = 35^{1+1}$

$35 * 35 = 35^{2}$

Rotational symmetries for a trapezoid

dezoksy [38]

Answer:

A trapezoid has no axes of reflectional symmetry. A trapezoid has no rotational symmetry (Order 1). Note: Having no rotational symmetry means that the figure must be rotated a full 360º to again appear in it original position.
