Answer:
f(x) = -5x-3
Step-by-step explanation:
f(x) = ax + b
f(2)=-13 & f(-3) =12
2a + b = -13
-3a+ b = 12
_________-
5a = -25
a = -5
b= -13+10= -3
so the formula of f(x) = -5x -3
Answer:
Step-by-step explanation:
In a right angled triangle, we have perpendicular, hypotenuse and base.
The hypotenuse is the longest side and opposite to the right angle. the side having 90 degree angle is perpendicular.
Applying formulas we can find the values:
the formulas are : cos (Ф) = Base / hypotenuse
sin (Ф) = Perpendicular / hypotenuse
tan (Ф) = Perpendicular / Base
11. cos z
cos z = Base / hypotenuse
cos z = 12/15
12. cos C
cos C = base / hypotenuse
cos C = 38/45
13. tan C
tan C = Perpendicular/ Base
tan C = 40/30
14. tan A
tan A = Perpendicular/ Base
tan A = 21/20
15. tan C
tan C = Perpendicular/ Base
tan C = 12/35
16. tan X
tan X = Perpendicular/ Base
tan X = 30/40
17. sin Z
Sin Z = Perpendicular / Hypotenuse
sin Z = 35/37
18. sin z = Perpendicular / Hypotenuse
sin z = 30/50
The value of 8 is in the hundred thousands

well by looking at it , it would be for a.
Answer:
The answer to your question is: 53 in²
Step-by-step explanation:
Area = ?
Process: divide the shape in one rectangle and one triangle.
Area of rectangle
A = base x height
A = 8 x 6
A = 48 in²
Area of rectangle
base = 13 - 8
= 5 in
height = 6 - 4
= 2 in
Area = (b x h) / 2
= (5 x 2) / 2
= 10 / 2
= 5 in²
Total area = 48 + 5 = 53 in²
