we have the function

we know that
In the equation of the exponential function of the form

a is the initial value
b is the base
x is the exponent
The initial value is the value of the function when the value of x is equal to zero
in this problem
for 


the initial value is the point 
therefore
the answer in the attached figure
Answer:
9cm
Step-by-step explanation:
Area of trapezium=(1/2)×(a+b)h
A=33
a=2
b=?
h=6
(1/2)(2+b)(6)=33
(1/2)(12+6b)=33
6+3b=33
3b=33-6
3b=27
b=27÷3
b=9
Answer:
2
Step-by-step explanation:
Step-by-step explanation:
- 2x-2y=-6
3x+4y=8
multiply equation (1) by 3 and equation (2) by 2
- 6x-6y=18
6x+8y=16
Add
2y=34
y= 34÷2
y=17
substitute 17 for y in equation (2)
3x+4y=8
3x+4(17)=8
3x+68=8
3x=8-68
3x=-60
x=-60÷3
x=-20
x=-20,y=17
6x + 4x + 10 = 180
10x = 170
x = 17
mCA = 4(17) + 10 = 68 + 10 = 78
Answer:
mCA = 78°
