Answer:

  6.2 feet

Step-by-step explanation:

The mnemonic SOA CAH TOA reminds you of the relationship between angles and sides of a right triangle. Here, we have the side opposite the 58° angle, and we want to know the side adjacent. The relevant relation is ...

  Tan = Opposite/Adjacent

  tan(58°) = (10 feet)/x

  x = (10 feet)/tan(58°) ≈ 6.249 feet

The length of the shadow is about 6.2 feet.

Answer:

1) x ≅ 51.34°

2) y ≅ 38.66°

Step-by-step explanation:

In the right triangle given in the figure

∵ The triangle has a right angle

∴ Angles x and y are acute angles and the sum of their measures is 90°

→ By using the trigonometry function tan

∵ tan(x) = opposite side to x/adjacent side to x

∵ The opposite side to x = 10

∵ The adjacent side to x = 8

→ Substitute them in the rule above

∴ tan(x) = [tex]\frac{10}{8}[/tex] = [tex]\frac{5}{4}[/tex]

→ Use the inverse of tan to find x

∵ x = [tex]tan^{-1}[/tex]([tex]\frac{5}{4}[/tex])

∴ x = 51.34019175

∴ x ≅ 51.34°

∵ x + y = 90°

∴ 51.34 + y = 90

→ Subtract 51.34 from both sides

∴ y ≅ 38.66°

4p+ 5

Step-by-step explanation:

Given that :

Point stored per quarter = p

Number of quarters = 4

Point scored in overtime = 5

total number of points the basketball player scores during all four quarters and overtime?

(Point scored per quarter * number of quarters) + point scored in overtime

(p * 4) + 5

Answer:

k=-20

Step-by-step explanation:

-14=k+6

subtract 6 from both sides

-20=k

Answer:

k=-20

Step-by-step explanation:

-14=k+6

Really there is only one step subtracting 6 from both sides because it is a positive and needs to leave the equation:

-14=k+6

-6      -6

Which would be k=-20

Answer:

(x+12)^2=84

Step-by-step explanation:

x^2+24x+60=0

x^2+24x=-60

x^2+24x+(24/2)^2=-60+(24/2)^2

(x+24/2)^2=84

(x+12)^2=84 (ans)

Answer:

x = 31

Step-by-step explanation:

The sum of the internal angles = 180°

then:

2x-5 + x+10 + 2x+20 = 180

5x + 25 = 180

5x = 180 - 25

5x = 155

x = 155/5

x = 31

Check:

2*31 - 5   +  31+10   +  2*31 + 20  = 180

62-5  +   41   +  62+20 = 180

57 + 41 + 82 = 180

Answer:

b =950d

Step-by-step explanation:

The manufacturer makes 950 bulbs a day. So, you have to multiply the number of days by 950 to get the number of bulbs made. This can be written as an equation:

b = 950d

Hope this helps :)

An equation to find the number of bulbs b the manufacturer make in any number of days d will be written as b =950d.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a manufacturer produces 950 light bulbs per day.

The equation can be written as:-

b = 950d

Is there supposed to be a picture or something? I don't see anything.

Answer:

305

Step-by-step explanation:

If she is at day 19, that means you have to multiply 15 (phones repaired each day)  times 19 (19th day) in order to get how many phones she has counted which is 285. To find how much she has left, you have to subtract 285 from 590 which gets you 305.

g(x) = 1/x - 2

g^(-1) => x = 1/g(x) - 2

g^(-1) => x + 2 = 1/g(x)

g^(-1) => g(x)(x + 2) = 1

g^(-1) => g(x) = 1/(x + 2)

Answer: D. g^(-1) = 1/(x + 2)
