Answer:

59.04°

Step-by-step explanation:

Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.

We solve using the Trigonometric function of Tangent

tan x = Opposite/ Adjacent

tan x= 50 ft/30ft

x = arc tan (50 ft/30 ft)

x = 59.036243468°

Approximately = 59.04°

Answer:

(-1,-4)

Step-by-step explanation:

Answer:

one solution

Step-by-step explanation:

-2x - 4 = x - 5

-3x - 4 = -5

-3x = -1

x = 1/3

y = 1/3 - 5

y = 1/3 - 15/3

y = -14/3

(1/3, -14/3)

Answer:Percent Increase n the number of parts usually made = 80%

Step-by-step explanation:

Percent Increase = (Increase / Initial Number of parts made daily)  X 100/1

Initial Number of parts made daily = 45

Current number of parts ,made daily = 81

Percent Increase = 81-45/ 45 x 100

=36/45 x100/1

= 0.8 x 100

= 80%

Answer:

80 percent

The Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x

Let the distinct real zeros of the required polynomial be 0, 1 and -1.

The equivalent factors will be x(x-1)(x+1)

To get the required polynomial, we will take the product of the factors as shown:

P(x) = x(x-1)(x+1)

P(x) = (x+1)(x-1)x

P(x) = x(x²-1)

P(x) = x³ - x

Hence the Polynomial of degree 3 with three distinct real zeros and a positive leading coefficient is P(x) = x³ - x

Answer:

Angle PSQ is 61°

Step-by-step explanation:

In the triangle ΔPQR, we have;

m∠QPS = 65°

m∠PRQ = 43°

Line PSR is a straight line

m∠PQS : m∠SQR = 3:1

Therefore;

∠PQR = 180° - (∠QPS + ∠PRQ), by the angle sum theorem of a triangle

∴ ∠PQR = 180° - (65° + 43°) = 72°

∠PQR = 72°

∠PQR = m∠PQS + m∠SQR by angle addition postulate

m∠PQS : m∠SQR = 3:1

∴ m∠PQS = 3 × m∠SQR

∴ ∠PQR = m∠PQS + m∠SQR = 3 × m∠SQR + m∠SQR = 4 × m∠SQR

∠PQR = 4 × m∠SQR

∴ 4 × m∠SQR = ∠PQR = 72°

m∠SQR = 72°/4 = 18°

m∠PQS = 3 × m∠SQR = 3 × 18° = 54°

m∠PQS = 54°

∠PSQ = 180° - (∠QPS + ∠PQS) by the angle sum theorem

∴ ∠PSQ = 180° - (65° + 54°) = 61°

Angle ∠PSQ = 61°.

Answer:

-0.0714 approx

Step-by-step explanation:

78x − 12 = 316x + 5

Bring all the like terms together

78x -316x = 5 + 12

-238x = 17

∴ x = 17 ÷ -238 = -0.0714 (rounded up to 3 significant figures)

Airplane rides (3/5 ) and Bumper cars(7/12)

Step-by-step explanation:

The airplane rides is 3/5 full the Ferris wheel is 3/8 full the bumper cars are 7/12 full

what fraction of these rides are more than a half

Half = 1/2 = 0.5

Hence, we convert the fractions to decimals

The airplane rides is 3/5 full

= 3/5 = 0.6

The Ferris wheels is 3/8 full

= 3/8 = 0.375

The bumper cars are 7/12 full

= 7/12 = 0.583

The fraction of these rides that are more than a half are:

Airplane rides (3/5 ) and Bumper cars (7/12)

Answer:

Solve systems of two linear equations in two variables algebraically, and estimate solutions by graphing the equations. Solve simple cases by inspection. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6.

Answer: The functions values are greater than 0 over the interval.

Step-by-step explanation:

To tell if a function is positive over a given interval, see if it's below the x-axis or if it's under (since the x-axis represents 0).

If the interval is above the x-axis, it's positive (greater), and if it's below, it's negative (less).
