An art museum opens at 9 a.M. And closes at 5 p.M. The function V gives the number of visitors in a museum h hours after it open
liubo4ka [24]

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

Stonehenge is a circular arrangement of massive stones near Salisbury, England. A viewer at V observes the monument from a point
Marysya12 [62]

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°

What is he total coast to print exactly 15 copies?
artcher [175]

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

Please show the steps for this question <br> Divide z4 by z-3
dsp73
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.
