Slope=

Mathematics
1 answer:
elixir [45]3 years ago
3 0

Point 1 (0, - 2)

Point 2 (8,0)


Slope = (y2-y1)/(x2-x1)= (0-(-2))/(8-0)=2/8=1/4

y-intercept (from the Point 1 (0, - 2)) is -2.


Equation : y=(1/4)x - 2


Coordinates to test are (4,-1).


y=(1/4)x - 2

-1=(1/4)*4 -2

-1=1-2

-1=-1 True

Use a calculator to find a decimal approximation for the following trigonometric function sin 28°48
Bumek [7]

The decimal approximation for the trigonometric function sin 28°48' is

Given the trigonometric function is sin 28°48'

The ratio between the adjacent side and the hypotenuse is called cos(θ), whereas the ratio between the opposite side and the hypotenuse is called sin(θ). The sin(θ) and cos(θ) values for a given triangle are constant regardless of the triangle's size.

To solve this, we are going to convert 28°48' into degrees first, using the conversion factor 1' = 1/60°

sin (28°48') = sin(28° ₊ (48 × 1/60)°)

= sin(28° ₊ (48 /60)°)

= sin(28° ₊ 4°/5)

= sin(28° ₊ 0.8°)

= sin(28.8°)

= 0.481753

Therefore sin (28°48') is 0.481753.

Three experts gave opinions on how long a task will take to finish. The estimates were 29, 10, and 12 days (in no particular ord
nirvana33 [79]

Answer:

15

Step-by-step explanation:

PERT estimate is a measuring strategy that is based on a weighted average. It is used in measuring the uncertainty and risk via three estimates to determine an estimated likelihood for a project's cost or period of completion.

The formula is (O + 4M + P) ÷ 6

Where P is the most pessimistic = 29

M is the most likely = 12

O is the most optimistic = 10

Hence we have (10 + [4*12]+ 29) ÷ 6

= (10 + 48 + 29) ÷ 6

= 87÷6 = 14.5 ≈ 15

Rounded figure is equal to 15.

Hence the final answer to the question is 15
