Answer:
The value of mEFD = 214°
Step-by-step explanation:
Given that the measure of the degree of one of the central angles of an inner circle is 146°.
We know that sum of all central angles is 360°.
In other words, in our case
mEFD + 146° = 360°
Thus, we can determine the mEFD using the equation
mEFD + 146° = 360°
so subtracting 146° to both sides
mEFD + 146° - 146° = 360° - 146°
mEFD = 214°
Therefore, the value of mEFD = 214°
Answer:
Step-by-step explanation:
y=ax²+bx+c
x=0,y=0,c=0
y=ax²+bx
2=9a+3b (×-5)
3=25a+5b(×3)
add
9-10=75a-45a+15b-15b
30a=-1
a=-1/(30)
2=9×(-1/30)+3b
3b=2+3/10=23/10
b=23/30
y=-1/30 x²+23/30=-1/30(x²+23x+(23/2)²)+1/30 ×(529/4)
y=-1/30(x+23/2)²+529/120
the last pair is statements are true.
The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00
Equation: f(z)=20+5z
Step-by-step explanation:
Given,
Delivery cost of 6 floral arrangements = $50.00
Delivery cost of 12 floral arrangements = $80.00
Let,
x be the constant rate for each floral arrangement.
y be the initial value.
According to given statement;
6x+y=50.00 Eqn 1
12x+y=80.00 Eqn 2
Subtracting Eqn 2 from Eqn 1

Dividing both sides by 6

Putting in Eqn 1;

The constant rate for 1 floral arrangement is $5.00 and inital value is $20.00
Equation for the function;
Let z be the number of floral arrangements.
f(z) = initial fee + 5*Number of floral arrangements
f(z) = 20+5z
