Answer:

$(6x+8)(x-1)$

Step-by-step explanation:

We can separate the 2x into -6x + 8x. Then this will give us $6x^2 - 6x + 8x - 8 = 0$ . Now we can factor out a 6x and an 8 to give us $6x(x-1) + 8(x-1) = (6x+8)(x-1)$ by the distributive property.

Hope this helps! :)

A political action committee is interested in finding out what proportion of voters will

balandron [24]

Answer:

$n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875$

And rounded up we have that n=31

Step-by-step explanation:

First we need to find the critical value for the margin of error desired. The confidence level is 0.95 so then the significance is $\alpha=1-0.95=0.05$ and the critical value for this case would be:

$z_{\alpha/2} =\pm 1.96$

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

And on this case we have that $ME =\pm 0.09$ and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}$ (b)

The estimated proportion for this case is $\hat p =0.93$ . And replacing into equation (b) the values from part a we got:

$n=\frac{0.93(1-0.93)}{(\frac{0.09}{1.96})^2}=30.875$

And rounded up we have that n=31

To find the height of a pole, a surveyor moves 160 feet away from the base of the pole and then, with a transit 6 feet tall, mea

Artyom0805 [142]

Answer:

306.8 feet

Step-by-step explanation:

Refer the attached figure .

A surveyor moves 160 feet away from the base of the pole i.e. ED = 160 m

Referring the image .

AC=ED=160 m

A transit i.e. AE is 6 feet tall.

AE = CD=6 feet

With a transmit the angle of elevation to the top of the pole to be 62° i.e. ∠BAC = 62°

To Find BC , use tigonometric ratio.

$Tan\theta = \frac{Perpendicular}{Base}$

$Tan 62^{\circ}=\frac{BC}{AC}$

$Tan 62^{\circ}=\frac{BC}{160}$

$1.88*160=BC$

$300.8=BC$

Now, the height of the pole = BC+CD =300.8+6=306.8 feet

Hence the height of the pole is 306.8 feet
