The answer is X = 12.
This is how to get that answer: the formula for the intersecting secant and tangent outside the circle is a^2 = b(b+c) If you use the numbers in the pic you will get x^2 = 9(9+7) so the number after the equal sign will be 144, so x^2 = 144. To undo the square youre gonna use the square root on both sides, so you have X = 12.
Answer:
The answer is 3 1/2.
Step-by-step explanation:
-There are 2 simple ways to do this.
-The first is just subtracting 3/4 and 1/4 which equals 2/4 or 1/2.
-The second way is to turn it into an improper fraction.
-(5*4)+3=23 and (2*4)+1=9.
-23/4-9/4=14/4
-14/4=3 1/2
Answer:
<u>y=90x−410</u>
Step-by-step explanation:
in point-slope form, this would be...
y−130=90⋅(x−6)<-----
If you convert this to slope-intercept form this would be...
y=90x−410
Change in temp = -3/h
From noon to 1pm, 1 hour has passed, so temp = 0 degrees - 3 degrees = -3 degrees
From 1pm to 2pm, 1 hour has passed, so temp = -3 degrees - 3 degrees = -6 degrees
From 2pm to 3pm, 1 hour has passed, so temp = -6 degrees - 3 degrees = -9 degrees
From 3pm to 6pm, 3 hours have passed, so temp
= -9 degrees - (3 × 3 degrees)
= -9 degrees - 9 degrees = -18 degrees
This problem can be simplified by remembering that since
, we have
. Then we have
.
