Answer:

100.53+80 = 180.53(rounded)

32pi+80 (not rounded)

Step-by-step explanation:

Triangle area = 1/2 b*h

Semi circle = (pi r^2)/2 - radius= diameter/2

h= 10 m

b=16 m

1/2*16*10

8*10

80 m

Semi circle

(pi8^2)/2

32pi

100.53 (rounded)

Add triangle +semicircle.

100.53+80 = 180.53(rounded)

32pi+80 (not rounded)

Find the value of each expression using the given information cot∅=8, csc&lt;0<br> find sin ∅
Oksana_A [137]

9514 1404 393

Answer:

  sin(∅) = -√65/65

Step-by-step explanation:

The identities that relate the cotangent, the cosecant, and the sine are ...

  csc² = 1 +cot²

  sin = 1/csc

_____

For the given values, we find ...

  csc(∅)² = 1 +cot(∅)² = 1 +8² = 65

  csc(∅) = -√65 . . . . . . . . . . . . . . . . square root with attention to sign

  sin(∅) = -1/√65 = (-√65)/65

Law of cosines <br><br> HELP MES
Lorico [155]

Answer:

70.52 degrees

Step-by-step explanation:

To find the angles, we must first find the lengths of each side of the triangle. Adding up the respective radii, we can see that

XY = 5+4 = 9 CM

XZ = 6+5 = 11 CM

ZY = 4+6 = 10 CM

Now we can apply the cosine rule

C\:=\:\sqrt{A^2+B^2-2ABcosx}

We need to rearrange the rule to solve for x, our missing angle

x\:=\:cos^{-1}\left(\frac{a^2+b^2-c^2}{2ab}\right)

solving for our unknown angle:

x\:=\:cos^{-1}\left(\frac{9^2+10^2-11^2}{2\cdot 9\cdot 10}\right)

x\:=\:70.52^{\circ }

Therefore angle YXZ is 70.52 degrees

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!
Keith_Richards [23]

Answer: \bold{D.\ \bigg(-\infty, \dfrac{ln\ 4}{0.2}\bigg)}

<u>Step-by-step explanation:</u>

y=\dfrac{c}{1+ae^{-rx}}\qquad \text{where growth rate increases from}\ -\infty\ to\ \dfrac{ln\ a}{r}

f(x) = \dfrac{15}{1+4e^{-0.2x}}\qquad \rightarrow \qquad a=4, r=0.2

\text{So, the growth rate increases over the interval}\ \bigg(-\infty, \dfrac{ln\ 4}{0.2}\bigg)
