Answer:

[tex]A=784\pi[/tex]

Step-by-step explanation:

Calculate area of the circle:

[tex]A=784\pi[/tex]

The height of the lighthouse from the top of the cliff is 161.2 cm

The situation forms two right angle triangle.

Right angle triangle has one of its angles as 90 degree. Therefore, the sides and angles can be found using trigonometric ratios as follows;

tan 51.3 = opposite / adjacent

where

opposite = height of cliff and light house = x

adjacent  = distance of the ship from the base of the cliff

Therefore,

tan 51.3 = x / 980

cross multiply

x = 980 tan 51.3

x = 1223.23995563 meters

tan 47.3 = opposite / adjacent

where

opposite = height of cliff = y

adjacent = distance of the ship from the base of the cliff

tan 47.3 = y / 980

y = 980 tan 47.3

y = 1062.01582791 meters

The height of the lighthouse from the top of the cliff = 1223.23995563 -  1062.01582791 = 161.224127725  = 161.2 cm

Answer:

39.2 m/s

Step-by-step explanation:

Let a = 9.8 m/s^2, t = 8 sec, find the initial velocity v

After time t, the rock hit the ground, so the height h = 0

Use h = vt - at^2/2 = 0

v = at/2 = 9.8 * 8/2 = 39.2 m/s

Answer:

Step-by-step explanation:

Total Cost = 150 + 69.50*12

Total Cost = 150 + 834

Total Cost = 984

Hidden in that is a 6% sales tax

Cost before sales tax =  1.06 * x = 984. This is the key step. The 6% sales tax is hidden in the 1.06. So you call the original price = x.

1.06 * x = 984                 Divide by 1.06

x = 928.3                        without the sales tax

The question seems to be answered by 984. The sales tax is in that cost.

Answer:

68

Step-by-step explanation:

=> g²+13g

putting the value of g which is 4

=> 4²+13(4)

=> 16+52

=> 68

Answer:

68

Step-by-step explanation:

We simply just plug in 4 for g since the problem states that "g=4"

Which turns our expression to "[tex]4^{2} +13(4)[/tex]"

_________________________

We start by calculating what [tex]4^{2}[/tex] equals which is 16 (4 * 4)

Now we do 13 times 4 which is 52

52 + 16 = 68

Answer:

a) f(-8) = 1

b) f(-4) = 5

c) f(2) is undefined

Step-by-step explanation:

f(x) notation means "the function of x".  Therefore, for f(-8) you need to find the y value when x = -8.  Locate -8 on the x-axis and then follow up (or down) until you meet the curve/line.  Then find the corresponding y-coordinate of this point.

From inspection of the graph:

a) f(-8) = 1

b) f(-4) = 5

c) f(2) is undefined

Answer:

5 is the answer..................

Answer:

The triangle's area formula is half of the quadrilateral's area formula

Step-by-step explanation:

If we put triangle ONE on top of triangle MHS, we could compare each angle, and we would find that the corresponding angles are all congruent. If we measured the angles, we would find that the corresponding angles are congruent. Therefore, these quadrilaterals are similar.

Answer:

x <16/3

Step-by-step explanation:

7x - 4< 4(x+3)

Distribute

7x - 4< 4x+12

Subtract 4x from each side

7x-4x - 4< 4x-4x+12

3x-4 < 12

Add4 to each side

3x-4+4 < 12+4

3x<16

Divide each side by 3

3x/3 <16/3

x <16/3

Answer:

[tex]x = 10[/tex]

Step-by-step explanation:

[tex]\sqrt{x+6} =x-6\\[/tex]

square both sides:

[tex]\implies x+6=(x-6)^2[/tex]

Expand brackets:

[tex]\implies x+6=x^2-12x+36[/tex]

Collect and combine like terms:

[tex]\implies x^2-13x+30=0[/tex]

[tex]\implies (x-10)(x-3)=0[/tex]

[tex]\implies x=10, x=3[/tex]

Substitute values back into original equation:

[tex]x=10: \sqrt{10+6} =10-6 \implies 4 = 4 \ \ \checkmark[/tex]

[tex]x=3: \sqrt{3+6} =3-6 \implies 3 = -3 \ \ \textsf{incorrect!}[/tex]

Therefore, [tex]x=10[/tex] only

[tex]\\ \tt\rightarrowtail \sqrt{x+6}=x-6[/tex]

The total amount of rainfall is the sum of the rainfall on each day

The total amount of rainfall is [tex]3\frac 38[/tex] inches

From the dot plot, we have the following frequency table

Rainfall    Frequency

0                  4

1/8               5

1/4               1

3/8              2

1/2               1

1 1/4             1

So, the total amount of rainfall is:

[tex]Total = 0 * 4 + \frac 18 * 5 + \frac 14 * 1 + \frac 38 * 2 + \frac 12 * 1 + 1\frac 14 * 1[/tex]

Evaluate the sum

[tex]Total = 3\frac 38[/tex]

Hence, the total amount of rainfall is [tex]3\frac 38[/tex] inches
