Answer:

$(4 \pi+26)\ in$

Step-by-step explanation:

we know that

The perimeter of the figure is equivalent to the perimeter of a rectangle plus the perimeter of semicircle minus the length side of $8$ inches

step 1

<u>Find the perimeter of rectangle</u>

the perimeter of rectangle is equal to

$P=2(b+h)$

we have

$b=8\ in$

$h=9\ in$

substitute

$P=2(8+9)=34\ in$

step 2

<u>Find the circumference of semicircle</u>

the of circumference of semicircle is equal to

$C=\frac{1}{2}\pi D$

we have

$D=8\ in$

substitute

$C=\frac{1}{2}\pi (8)=4 \pi\ in$

step 3

Find the perimeter of the figure

$34\ in+4 \pi\ in-8\ in=(4 \pi+26)\ in$

if one card is drawn from a regular deck of cards, what is the probability the card will not be an ace?

satela [25.4K]

There are 52 cards in a deck of cards so that makes 52 your denominator. There are 4 aces in a deck of cards, so 52 - 4 = 48 making 48 your numerator. so the probability the card won't be an ace is 48 out of 52.

48/52 chance that the card will not be an ace.

Hope this helps you. :-)

Factor -1(x^(2)-3x-4) and pls show steps

soldi70 [24.7K]

Answer:(-x-1)(x-4)

Step-by-step explanation:

$-1(x^{2} -3x-4)$

factor the equation (multiples of 4 are 1 and 4 and 2 and 2) 4-1=1 so the factor you want to use are 1 and 4

-1(x +1)(x-4) -- -4+1=3

distribute the -1 into the first factor

(-x-1)(x-4)

Answer:

$\tan \dfrac{\theta}2 = \dfrac{1}2$

Step by step Explanation:

$\sin \theta = \dfrac{\text{Perpendicular} }{\text{Hypotenuse}} = \dfrac{12}{15}\\\\\\\cos \theta = \dfrac{\text{Base}}{\text{Hypotenuse}}= \dfrac{9}{15}\\\\\text{Now,}\\\\\tan \dfrac{\theta}2 = \dfrac{\sin \tfrac{\theta}2}{\cos \tfrac{\theta}2}\\\\\\~~~~~~~~=\dfrac{2\cos \tfrac{\theta}2 \sin \tfrac{\theta}2 }{2\cos^2 \tfrac{\theta}2}~~~~~~;\left[\text{Multiply by}~ 2\cos\tfrac{\theta}2 \right]$

$=\dfrac{\sin \theta}{1+ \cos \theta}~~~~~~~~~~~~;[2 \sin x \cos x = \sin 2x ~ \text{and}~ 2\cos^2 x =1+\cos 2x]\\\\\\=\dfrac{\tfrac{12}{15}}{1+ \tfrac{9}{15}}\\\\\\=\dfrac{\tfrac{12}{15}}{\tfrac{24}{15}}\\\\\\=\dfrac{12}{15}\times \dfrac{15}{24}\\\\\\=\dfrac{12}{24}\\\\\\=\dfrac{1}2$
