Answer:
What the equation is telling us is that after opening for 1 hour 15 minutes, there were 28 visitors
Step-by-step explanation:
The function we are given is ;
V(1.25) = 28
what this mean is that the number of visitors in the museum after 1.25 hours of opening is 28
1.25 hours is same as 1 hour (0.25 * 60) minutes
What is in the bracket is trying to convert the 0.25 hours to minutes
Since 1 hour is 60 minutes, 0.25 will be (0.25 * 70)
Which is 1 hour 15 minutes
So after opening for 1 hour 15 minutes, the museum had 28 visitors
We are given the following measures:
mAB = 48°
mDC = 180°
In the given figure above, we can say that angle AVB is
an exterior angle which intercepts two arcs, arc AB and arc DC, therefore in
this case to solve for the measure of angle mAVB, we have to make use of the
formula which is in words:
Find the difference between the measures of the two
intercepted arcs and divide by 2, or expressed mathematically in this case as:
mAVB = (mDC – mAB) / 2
Substituting the given values into the equation:
mAVB = (180° - 48°) / 2
mAVB = 66°
You would start by finding out how much 10 and 20 cost per copy
10: 40-25 = 15/10 = $1.50 dollars per copy
20 (This is for checking your math, not required): 55-25 = 30/20 = $1.50 dollars per copy
So, to find 15 copies you would use this formula: 25 + 1.5x
25 + 1.5(15)
25 + 22.5
$47.50 for 15 copies
Now for the second question:
160 - 25 = 135/1.5 = 90 copies
90 copies for $160
Z^4 / z^-3 = z^7 - when you divide numbers written in exponential form, you keep the base and subtract the exponents. z^4 divided by z^-3 = z^ (4- (-3)) = z^7.
