Your answer will be 3x^2-7x.
Two complementary angles = 90°
X = 18+ 2y
X + y = 90
Plug first equation into second
18 + 2y +y = 90
18 + 3y = 90
18 – 18 +3y = 90 – 18
3 y = 72
3y/3 = 72/3
Y = 24
Plug y into 2nd formula
X + 24 = 90
X + 24 -24 = 90 – 24
X = 66
Answer:
It has amplitude of
.
It is a horizontal shift of the parent function
units left.
Step-by-step explanation:
We have the function,
.
It is clear that the parent function is
.
So, we see that,
The amplitude of the function f(x) is
, which gives,
.
Also, g(x) is translated
units to the left, which gives,
.
Further, the function is translated 1 unit downward, resulting in
.
So, the correct options are,
It has amplitude of
.
It is a horizontal shift of the parent function
units left.
Answer:
a.12/13
Step-by-step explanation:
- FORMULA: sine of an angle in a triangle is given by,

- here, in the given triangle PQR, for angle 'p'
opposite side= QR
adjacent side= PQ
hypotenuse=PR
- Therefore, sine of angle p=

- Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.
- hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems
