Lisa wants to measure the height of a tree. She sights the top of the tree, using a mirror that is lying flat on the ground. The mirror is 38 ft from the tree, and
Lisa is standing 6.2 ft from the mirror, as shown in the figure. Her eyes are 6 ft above the ground. How tall is the tree? Round your answer to the nearest foot.
(The figure is not drawn to scale.)

Answer:

C = 25.94°

Step-by-step explanation:

By applying cosine rule in ΔABD,

BD² = AB² + AD² - 2(AB)(BD)cosA

BD² = (5.8)² + (6.2)² - 2(5.8)(6.2)(cos27°)

BD² = 33.64 + 38.44 - 64.08

BD² = 8

BD = √8

By applying cosine rule in ΔBCD,

BD² = BC² + CD²- 2(BC)(CD)cosC

(√8)² = (5.4)²+ (3.3)² - 2(5.4)(3.3)cosC

8 = 29.16 + 10.89 - 35.64cosC

35.64cosC = 32.05

cosC = 0.89927

C = [tex]\text{cos}^{-1}(0.89927)[/tex]

C = 25.94°

By using cosine formula of triangles we got that measure of ∠C is 25.94 °

Quadrilateral is a closed shape with 4 sides and 4 corners.

Here given that

AB=5.8 cm

BC=5.4 cm

CD=3.3 cm

AD=6.2 cm

and [tex]\angle A=27[/tex] °

in [tex]\triangle \mathrm{ABD}[/tex]

Applying cosine formula

[tex]$$\begin{aligned}&\mathrm{BD}^{2}=\mathrm{AB}^{2}+A D^{2}-2(\mathrm{AB})(\mathrm{BD}) \cos A \\\\&\mathrm{BD}^{2}=(5.8)^{2}+(6.2)^{2}-2(5.8)(6.2)\left(\cos 27^{\circ}\right) \\\\&\mathrm{BD}^{2}=33.64+38.44-64.08\\ \\&\mathrm{BD}^{2}=8 \\\\&\mathrm{BD}=\sqrt{8}\end{aligned}$$[/tex]

Now in [tex]\triangle B C D[/tex]

Applying cosine formula

[tex]$$\begin{aligned}&\mathrm{BD}^{2}=\mathrm{BC}^{2}+\mathrm{CD}^{2}-2(\mathrm{BC})(\mathrm{CD}) \cos \mathrm{C} \\\\&(\sqrt{8})^{2}=(5.4)^{2}+(3.3)^{2}-2(5.4)(3.3) \cos \mathrm{C} \\\\&8=29.16+10.89-35.64 \cos \mathrm{C}\\ \\&35.64 \cos \mathrm{C}=32.05\\ \\&\cos \mathrm{C}=0.89927 \\\\&\mathrm{C}=\cos ^{-1}(0.89927) \\&\end{aligned}$$[/tex]

C=25.94 °

By using cosine formula of triangles we got that measure of ∠C is 25.94 °

Answer:

D. a translation right 10 and up 9

Step-by-step explanation:

In order to find the translation, you can take two corresponding points and find the difference in their x's and y's. For example, I'll use N and N':

Step 1) N (-3, -5) and N' (7, 4)

Step 2) difference in y: 4 - (-5) = 9; difference in x: 7 - (-3) = 10

Step 3) a translation right 10 units and up 9 units

1) identify what coordinates points N an N' are

2) find the difference in the points

3) identify whether he shape moved up or down, and left or right. You can see it moved up and right, so you you can tell it moved up 9 since that's the difference in y's and right 10 since that's the difference in x's

Radius =  6.40

Diamater - 12.70

Step-by-step explanation:

hope this helped!

The diameter and radius of a circle to the nearest hundredth with the given circumference, C = 40 inches is 12.73 inches and 6.37 inches.

Circumference of a circle is defined as the total length of the boundary of the circle.

The concept is same as the perimeter for straight sided figures.

The formula to calculate the circumference of the circle is given by,

Circumference = 2πr

Here r is the radius of the circle.

Given C = 40 inches

2πr = 40

πr = 40 / 2

πr = 20

r = 20/π = 6.366 ≈ 6.37

Diameter = 2 × radius = 2r = 12.732 ≈ 12.73

Hence the diameter and radius are 12.73 inches and 6.37 inches.

Answer:

  59°

Step-by-step explanation:

The law of cosines tells you ...

  h² = f² +g² -2fg·cos(H)

Solving for angle H gives ...

  H = arccos((f² +g² -h²)/(2fg)) = arccos(725/1400) ≈ 58.811°

Answer:

15,103.05

Step-by-step explanation:

Total amount in the saving account after 5 years in which the  annual interest, compounded continuously, is $15,103.85.

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{100n}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

$13,000 is deposited into a savings account with an annual interest rate of 3% compounded continuously.

The amount in account after 5 years can be calculated with the above formula as,

[tex]A=13000\times\left(1+\dfrac{3}{12\times100}\right)^{12\times5}\\A=15101.02[/tex]
