Answer:
c. 9/12
Step by step explanation.
Given: sin = 9/15
and,


thus, find adj. side
by using Pythagoras theorem

then,
let adj. side be a^

thus,
adj. side is 12
then,
tan of the angle = 9/12

Answer:
option D
(-1,-3) and (3,13)
Step-by-step explanation:
Given in the question two equations
y = 4x + 1
y = x² + 2x - 2
Equate both functions
4x + 1 = x² + 2x - 2
rearrange the x term and constant
-x² + 4x - 2x + 2 + 1 = 0
-x² + 2x + 3 = 0
factors
-x * 3x = -3x²
-x + 3x = 2x
-x² -x + 3x + 3 = 0
-x(x+1) +3(x+1) = 0
solve
(x+1)(3-x) = 0
x = -1
and
x = 3
Plug these values in equation to find y
x = -1
y = 4(-1)+ 1
y = -3
x = 3
y = 4(3)+ 1
y = 13
There are 12 inches per foot. If the tree is 48 feet tall, it is 48 x 12 = 576 inches tall.
= 6.25%
= 0.0625
= 625/10000
= 1/16
