Which of these is equal to cos 47°?
a. cos 43°
b. sin 43°
c. tan 43°
d. cos 133°
B.....
cos (47°)= sin (90°-47°)=sin (43°) [complementary angles]
Answer B
Answer:
(13 x + 6) (x - 2)
Step-by-step explanation:
Factor the following:
13 x^2 - 20 x - 12
Factor the quadratic 13 x^2 - 20 x - 12. The coefficient of x^2 is 13 and the constant term is -12. The product of 13 and -12 is -156. The factors of -156 which sum to -20 are 6 and -26. So 13 x^2 - 20 x - 12 = 13 x^2 - 26 x + 6 x - 12 = x (13 x + 6) - 2 (13 x + 6):
x (13 x + 6) - 2 (13 x + 6)
Factor 13 x + 6 from x (13 x + 6) - 2 (13 x + 6):
Answer: (13 x + 6) (x - 2)
The type of function that best models the data in the table is the quadratic function
<h3>How to determine the function type?</h3>
The table of values is represented as:
x: 4 6 8 10 12
y : 118 142 150 142 118
From the above table, we can see that:
- The y values increase from 118 to 150
- The y values then decrease to 118
- The x values increase
This is only possible in a quadratic function
Hence, the type of function that best models the data in the table is the quadratic function

22%
So it would be 21%, 0.21, 11/50, 2/9.
Answer:
1 yard = 3 feet
Keeping this in mind, we need to multiply the yard lengths by 3 to convert the measurements to feet.
8 feet x 3 = 24 yards
6 feet x 3 = 18 yards
5 feet x 3 = 15 yards
So
8 ft = 24 yd
6 ft = 18 yd
5 ft = 15 yd
plz mark brainliest if this helped :)
