Answer:

Step-by-step explanation:

As we move along the graph from x = 2 to x = 3 (a change of 1), y decreases from y = 100 to y = 0 (a change of -100). Thus, the slope of this line is

m = rise / run = -100/1 = -100.

The y-intercept is the point where the graph crosses the y-axis, and is (0, 200).

The equation of this line in slope-intercept form is y = -100x + 200

Write the statement for given expression a) x+3 b) 8-2x K/2 +1

kiruha [24]

Step-by-step explanation:

Decide which of the following are quadratic equations.

(1) x2 + 5x – 2 = 0

(2) y2 = 5y – 10

(3) y2+

(4) x+

=-2

(5) (m + 2) (m – 5) = 0

(6) m3 + 3m2 – 2 = 3m3

ANSWER:

(1) x2 + 5x – 2 = 0

Only one variable x.

Maximum index = 2

So, it is a quadratic equation.

(2) y2 = 5y – 10

Only one variable y.

Maximum index = 2

So, it is a quadratic equation.

(3) y2+

⇒y3+1=2y

Only one variable y.

Maximum index = 3

So, it is not a quadratic equation.

(4) x+

=-2

⇒x2+1=-2x

Only one variable x.

Maximum index = 2

So, it is a quadratic equation.

(5) (m + 2) (m – 5) = 0

⇒m2-3m-10=0

Only one variable m.

Maximum index = 2

So, it is a quadratic equation.

(6) m3 + 3m2 – 2 = 3m3

Only one variable m.

Maximum index = 3

So, it is not a quadratic equation.

A squirrel in a long glide typically covers a horizontal distance of 16 m while losing 8.0 m in altitude. during this glide, wha

iragen [17]

Let the starting position be A, and the ending position of the glide be B.

The triangle ABC shown in the figure, is a right triangle with side lengths 16m and 0.8 m.

The angle of the squirrel's path below the horizon is BAC.

Using right triangle trigonometry:

tan(ABC)=(opposite side)/(adjacent side)=0.8/16=0.05

to find m(ABC) we calculate arctan(0.05) which is 2.86°

Answer: 2.86°
