Y= -(1/2)x+b
to get m you flip it so it is the reciprocal
-2= -(1/2)(6)+b
-2= -3+b add 3 on each side
1=b
y= -(1/2)x+1
Answer:
1.
= 3√10 2.
= 5 3.
= 6√2
Step-by-step explanation:
Use <u>Intersecting Secant-Tangent Theorem</u>:
If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.
1. In this circle, DB is a tangent and DA is a secant. They intersect at point D.
So DB² = DC x DA
² = 5 x (5 + 13)
² = 90
= √90 = 3√10
2. In this circle, FE is a tangent and FH is a secant. They intersect at point F.
So FE² = FG x FH
10² =
x 20
100 = 20![x](https://tex.z-dn.net/?f=x)
= 5
3. In this circle, NM is a tangent and NP is a secant. They intersect at point N.
So NM² = NO x NP
² = 4 x (4 + 14)
² = 72
= √72 = 6√2
Let h represent the height of the triangle.
... b = 10 + 3h . . . . . . the base is 10 inches more than 3 times the height
... A = (1/2)bh . . . . . . formula for the area of a triangle in terms of base and height
... 16 = (1/2)(10 +3h)h . . . . substitute the known values
... 3h² + 10h - 32 = 0 . . . . rearrange to standard form
... (h -2)(3h +16) = 0
... h = 2 or -16/3 . . . . . . . . the negative solution is extraneous
... b = 10 + 3·2 = 16 . . . . . use the relation between b and h
The base and height of the triangle are 2 inches and 16 inches, respectively.
