Answer:

∠MON = 57°

Step-by-step explanation:

∠LOM + ∠MON = ∠LON ← substitute values

3x + 20 + 2x + 33 = 113, that is

5x + 53 = 113 ( subtract 53 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

Hence

∠MON = 2x + 33 = (2 × 12) + 33 = 24 + 33 = 57°

Which equation is the inverse of 5y+4 = (x+3)^2 + 1/2?

katovenus [111]

we have

$5y+4=(x+3)^{2}+\frac{1}{2}$

Step 1

Swap x and y

$5x+4=(y+3)^{2}+\frac{1}{2}$

Step 2

Solve for y

$5x+4-\frac{1}{2}=(y+3)^{2}$

$(y+3)^{2}=5x+\frac{7}{2}$

Square root both sides

$(y+3)=(+/-)\sqrt{5x+\frac{7}{2}}$

$y=(+/-)\sqrt{5x+\frac{7}{2}}-3$

Step 3

Let

$f(x)^{-1}=y$

$f(x)^{-1}=(+/-)\sqrt{5x+\frac{7}{2}}-3$

therefore

<u>the answer is the option D</u>

$y=-3(+/-)\sqrt{5x+\frac{7}{2}}$

A girl is on the beach and the angle of elevation from her feet to the top of a lighthouse is 62' If the lighthouse is 30ft tall

soldi70 [24.7K]

Answer:

15.95 feets

Step-by-step explanation:

Given that:

Angle of elevation = 62°

Using trigonometric relation :

Tanθ = opposite / Adjacent

From the drawing attached :

Opposite = 30 feets

Distance between girl and lighthouse = d

Tan 62 = 30 / d

1.8807264 * d = 30

d = 30 / 1.8807264

d = 15.951283

d = 15.95 feets

Find the amount that is in the account if $4500 is compounded daily at 3.25% for 6 years

Sindrei [870]

Step-by-step explanation:

1st year interest calculated = 3.25/100 × $4500/1 = $146.25

2nd year principal = 1st year principal + 1st year interest = $4500 + $146.25 = $4646.25. 2nd year interest calculated = 3.25/100 ×$4646.25/1 =$151

3rd year principal = 2nd principal + 2nd year interest = $4646.25 + $151 = $4797.25. 3rd year interest calculated = 3.25/100 × $4797.25/1 = $155.91

4th year principal = 3rd year principal + 3rd year interest =$4797.25 + $155.91 =$4953.16. 4th year principal calculated = 3.25/100 × 4953.16/1 =$160.98

5th year principal = 4th year principal + 4 year interest = &4953.16 +$160.98 = $5114.14. 5th year interest calculated = 3.25/100 × 5114.14/1 =$166.21

6th year principal =5th year principal + 5th year interest = $5114.14 + $166.21 =$5280.35. 6th year interest calculated = 3.25/100 × 5280.35/1 =$171.61

Amount = main principal + compound interest =$4500 +&146.25 +$151+$155.91+$160.98+$166.21+$171.61 =$5451.96
