[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] sinθ = opposite over hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

Angle θ = 64°

Opposite Leg = <em>x</em>

Hypotenuse = 11

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute in variables [sine]: $\displaystyle sin(64^\circ) = \frac{x}{11}$
[Multiplication Property of Equality] Multiply 11 on both sides: $\displaystyle 11sin(64^\circ) = x$
Rewrite: $\displaystyle x = 11sin(64^\circ)$
Evaluate: $\displaystyle x = 9.88673$
Round: $\displaystyle x \approx 9.9$

Write each expression as an equivalent expression with a single logarithm. Assume xx, yy, and zz are positive real

Alekssandra [29.7K]

Answer:

$\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

Step-by-step explanation:

Given:

1/2(ln(xx + yy) − ln(zz))

Now,

From the properties of log function,

1) n × ln(x) = ln(xⁿ)

and,

2) ln(A) - ln(B) = $\ln\frac{A}{B}$

applying the properties in the given equation

we get the above equation as:

$\frac{1}{2}(\ln\frac{xx + yy}{zz})$

( using the property 2 we get (ln(xx + yy) − ln(zz) = $\ln\frac{xx + yy}{zz}$

or

⇒ $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$ ( using the property 1 i.e n × ln(x) = ln(xⁿ) )

expression as an equivalent expression with a single logarithm is $\ln(\frac{xx + yy}{zz})^{\frac{1}{2}}$

Simplify y^-3 <br><br> a.3/y<br> b.1/y^3<br> c.-3y<br> d.-1/y^3

nignag [31]

Answer:

b. $\frac{1}{y^3}$

Step-by-step explanation:

Here we are given $y^{-3}$ and are asked to simplify it. We are going to apply the law of exponents which says that

$a^{-n}=\frac{1}{a^n}$

Hence applying this rule in our problem we get, where a=y and n=3

$y^{-3}=\frac{1}{y^3}$

Hence our C) Option is correct

Sean has some candy bars that he wants to give away. He is going to give each person 1/18 of a bar, and he has 2 3/4 to give awa

julsineya [31]

Answer:

49 people

Step-by-step explanation:

Take the amount of candy and divide by the amount in a serving

2 3/4 ÷ 1/18

Change to an improper fraction

(4*2+3)/4 ÷ 1 /18

11/4 ÷ 1/18

Copy dot flip

11/4 * 18/1

198/4

49.5

Round down since people do not want half a serving
