Answer:
C. x = 18, y = 9
Step-by-step explanation:
In a 30-60-90 triangle,
longer leg = (shorter leg)
hypontenuse = 2(shorter leg)
In your case, the shorter leg = 9
therefore, y = 9 and x = 2(9) = 18

Step-by-step explanation:
a) To determine the 1-unit growth factor for <em>f</em>
= 2.1/1.75 = 1.2
b) To determine the 1-unit percent change for <em>f</em>
<em>=100 x 1-1.2/1 = 0.2 x 100= 20%</em>
<em>c) to determine the initial value of f</em>
<em>f(x)= abˣ , b =1.2 a=initial value</em>
<em>at (-1,2.1)</em>
<em>2.1= (1.2)⁻¹ x a</em>
<em>a = 2.1/(1.2)⁻¹ </em>
<em>a = 2.1 x 1.2 = 2.52</em>
<em />
<em>d) to determine the function formula for f</em>
<em>f(x)= abˣ = 2.52(1.2)ˣ</em>
Answer:
1400
Step-by-step explanation:
Given: Cost of Regular ticket = $9.50
Cost of Matinee tickets= $7
Total number of people= 5000
Total spending in watching movie= $44000.
Lets assume total number of people attended matinee be "x".
∴ Number of people attended Regualr show=
We know, total cost=
Now, forming an equation to show total spending on tickets.
⇒
Using distributive property of multiplication to multiply 9.50 with 5000 and -x.
⇒
⇒
Adding both side by 2.5x
⇒
subtracting both side by 44000
⇒
Dividing both side by 2.5
⇒
∴
Hence, number of people attended the matinee show are 1400.
