There is a theorem in Geometry stating that the square of the tangent segment (ST) is equal to the product of the external secant segment (TR) and the whole secant segment (TQ).
SQ x SQ = TR x TQ
SQ squared = 7 x 30
SQ squared = 210
SQ =
Answer:
11 m and 14 m
Step-by-step explanation:
Legs: x and y
---
1/2xy= 77 ⇒ xy= 154
√x²+y²= √317 ⇒ x²+y²=317
x²+y²+2xy= (x+y)²= 2*154+317= 625 ⇒ x+y= √625= 25
x= 25-y
xy=154 ⇒ y(25-y)= 154 ⇒ 25y- y²=154 ⇒ y²- 25y +154=0 ⇒ y=11 and y=14
x= 25-y= 14 and 11
The "compound amount" formula is A = P(1+r)^t.
Here, the Amount A(x) is (x)(1+0.03)^1= 1.03x.

Answer:
Step-by-step explanation:
$15 x 12Mths = $180
2 x 20 = $40 carlo gets back
$300 + $180 = $480
$480 - 40 = $440 is what carlo will spend in one year
Saves $40 from getting $2 back every time he works out
