Can someone help me with this one? it's due today at 9pm and I really don't know it!!! ​
Feliz [49]

Answer:

Radius: 7.5 cm  ;  Diameter: 15 cm

Step-by-step explanation:

The radius of a circle is basically the middle "halfway" point and in this case, it has already been given, 7.5 cm. The diameter is the middle line of the circle and to find the diameter, you must multiply the radius by 2, which is essentially 7.5 cm*2, and this gives you a diameter of 15 cm.

Hope this helps! :D

Find the equation of the line that passes through (-1,2) and is perpendicular to
Natalija [7]

Answer:

Remember that the slope of perpendicular lines are negative reciprocals of each other.

Step-by-step explanation:

y = 1 - 2x     the slope is -2     the value of the x term.

So the slope of the new line using point (- 1, 2)  is  1/2.

Now use y = mx + b where y = -1, x = 2, and m = 1/2 .

y = mx + b

-1 = 1/2(2) + b                solve for "b", the y-intersect

-1 =  1 + b

-2 = b

The line that is perpendicular to y = 1 - 2x  is  y = 1/2x - 2
