〽Hola User_______________

⭐Here is Your Answer..!!!

______________________

↪Cartesian Coordinates of the system....!!

↪X = rcos⊙ and Y = rsin⊙

↪since here Radius (r) = 10 units and Theta (⊙) = 225°

↪there fore substituting we get as ..

↪X = 10 ( cos 225° ) = 10 * -1/ root 2 = -7.071

↪Y = 10 ( sin 225° ) = 10 * -1/root2 = = -7.071

↪the cordinates are as follows

↪(x,y) = (-7.071, -7.071 )

Answer:

y = 3x +1
y = x + 3

Step-by-step explanation:

The bottom dot and the top dot are on a line with two other dots, the one at (0, 1) and the one at (1, 4). That line has a rise/run = 3/1. The point (0, 1) is its y-intercept, so its equation can be ...

y = 3x +1

The left dot and the lower right dot are on a line with three other dots. One of those (1, 4) is shared with the previous line. This line has a rise/run = 1/1. The point (0, 3) is its y-intercept, so its equation can be ...

y = x + 3

These two equations capture all of the coins.

Solve for b.<br> -t = 9(t - 10)<br> (WILL GIVE BRAINLIEST)

coldgirl [10]

Answer:

Do you mean solve for t?

If you do, the answer is 9.

Step-by-step explanation:

If we expand the equation out, we get:

-t = 9t - 90

If we move the -90 over to the left side and the -t to the right side, we get:

90 = 10t

Dividing both sides by 9, we get:

t = 9

29. BASKETBALL When Jerald shoots a free throw, the ball is 6 feet from the floor and has

tatuchka [14]

Answer:

a) j(t) = -16t^2 +20t +6

b) 1 second

c) less time

Step-by-step explanation:

The general equation for vertical motion is ...

$h(t)=-\dfrac{1}{2}gt^2+v_0t+h_0\\\text{where $v_0$ is the initial upward velocity, and $h_0$ is the initial height}$

a) j(t) = -16t^2 +20t +6 . . . . . filling in the given initial values, with g=32 ft/s^2

b) We want to find the larger of the solutions to ...

j(t) = 10 = -16t^2 +20t +6

Subtracting 6 and dividing by -4, we have ...

-1 = 4t^2 -5t

4t^2 -5t +1 = 0 . . . . add 1, put in standard form

(4t -1)(t -1) = 0 . . . . . factor

t = 1/4 or 1

The ball is in the air 1 second before reaching the hoop.

c) In generic terms, the equation of motion for a given shooting height at the same upward velocity will be ...

10 = -16t^2 +20t + h0

-16t^2 +20t +(h0 -10) = 0

Using the quadratic formula, we find the larger solution to be ...

t = (-(20) -√(20² -4(-16)(h0 -10)))/(2(-16))

t = (5/8) + √(64h0 -240)/32 = (5 +√(4h0 -15))/8

This value increases as h0 increases, so the ball will be in the air less time when Raymond shoots.
