Answer:

nth term is;

0.5n-0.5

Step-by-step explanation:

As we can see, the first term is 0

The common difference is 0.5-0= 1-0.5 = 1.5-1 = 0.5

Formula for nth term of an arithmetic sequence is;

a + (n-1)d

So we have

0 + (n-1) 0.5

= 0.5n-0.5

Someone solve for X please ? Step by step
irina1246 [14]
Start by distributing the 7 to both terms on the left hand side, and the 5 to both terms on the right hand side.

7(x - 2) = 5(x + 4)
7x - 14 = 5x + 20

Now, to solve for x, start by isolating the variable as much as you can.
7x - 5x = 20 + 14
2x = 34

x = 17

If the angle is in standard position and P(x, y) is a point on the terminal side of , and r is the distance from the origin to P
Ghella [55]

Answer:

x^2 + y^2 = r^2

Step-by-step explanation:

See image. "An angle in standard position" means the vertex (point part) of the angle is at the origin (0,0). And one side of the angle is glued onto the x-axis. The other side of the angle is free to rotate around the axis. That's the terminal side. Then there's a point P (x,y) on that side. See image. And r is labelled there. This set up makes a right triangle. So I put Pythagorean theorem as the answer here, but honestly if you are learning any right triangle theorems or trigonometry, you could use this set up. The leg that lays along the x-axis is x units long and the other leg is y units long. The hypotenuse is r units long.

A porch has the shape of a quarter circle. If the porch was a complete circle it would have a diameter of 5 ft. What is the appr
Sladkaya [172]
Normally, to find the area of a circle you'd do π × r^{2} so you have to find the radius by dividing 5 by 2 to get 2.5. Approximating pi as 3.14, you would do 3.14 × 2.5^{2} = 19.625. Because the porch is a quarter circle, you would then divide this by 4 to get 4.906. Rounded to the nearest square foot, your answer would therefore be 5 ft. I hope this helps!

Find the coordinates of the midpoint of the segment whose endpoints are H(10,1) and K(4,7)
zvonat [6]
Hey.
The answer is (7,4).
The change of x is -6. Divide that by two(=-3) and add it to the first x-coord and you get 7.
Do the same for your y-value(change =+6/2= +3) and you'll get 4.
