BRAINLIEST!!! HELP!!<br> In the figure...
V125BC [204]

Answer:

angle 1  = 61

Step-by-step explanation:

This is a little hard to explain without drawing a diagram .. but if you extend live vs until it intersects line p, you can form a triangle. Using corresponding angles rule for parallel lines, you have the exterior angle of the triangle with line p is 130, meaning the interior angle is 50 (angles on a straight line add to 180). Similarly, the interior angle of the triangle at S is 180 -111 = 69. So the two interior angles add to 50+ 69 = 119. Lastly, angle 1 is equal to the third interior angle of this triangle (due to vertically opposite angles being equal), so since angles in a triangle add to 180, angle 1 = 180 -119 = 61.

So we have the exponential equation: y=18582(0.90)^x
where
y is the number of visitors 
x are the weekends since opening

1. Since the opening weekend is the day of the the park's opening, we just need to replace x with 0 in our exponential equation to get the number of visitors on the opening weekend:
y=18582(0.90)^x
y=18582(0.90)^0
y=18582(1)
y=18582

We can conclude that there were 18582 visitors on the opening weekend.

2. Just like before, to find the approximate number of visitors on the ninth weekend, we just need to replace x with 9 in our exponential equation:
y=18582(0.90)^x
y=18582(0.90)^9
y=7199.0475
And rounded to the nearest integer:
y=7199

We can conclude that there were approximately 7199 visitors on the 9^{th} weekend.

3. Here we know that the number of visitors is 15051. Since y represents the number of visitors, we just need to replace y with 15051 in our exponential equation and solve for x:
y=18582(0.90)^x
15051=18582(0.90)^x
\frac{15051}{18582} =0.90^x
0.90^x= \frac{5017}{6194}
ln(0.90^x)=ln(\frac{5017}{6194})
xln(0.90)=ln(\frac{5017}{6194})
x= \frac{ln(\frac{5017}{6194})}{ln(0.90)}
x=2.0002
And rounded to the nearest whole number:
x=2

We can conclude that the number of visitors was about 15,051 after 2 weekends.
