Let the number of professors be x.

If there are 16 times as many students as professors, then the number of students will be:

If the number of students and professors is 42,500, then we have that:

Solving by dividing both sides by 17, we have:

Hence, we can calculate the number of students in the college to be:

Therefore, there are 40,000 students in the college.

Answer:

See below

Step-by-step explanation:

Maximum height will be found at the t value = - b/2a  

  b = 192    a = -16  

      so max height will be at   t = - 192/(2 * -16) = 6 s

Max height will be   h = -16(6^2) + 192(6)   = 576 ft

Answer:

6(3a+7b+1)

Step-by-step explanation:

36a+42v-18a+6
18a+42b+6
GCF=6
6(3a+7b+1)

The factor of the given expression is 6(3a+7b+1).

A factor is a number that divides another number, leaving no remainder.

Given an expression, 36a + 42b - 18a + 6

On factoring, we get,

36a + 42b - 18a + 6

= 18a+42b+6

= 6(3a+7b+1)

Hence, The factor of the given expression is 6(3a+7b+1).

Answer:

Step-by-step explanation:

equation of finding a midpoint is (x2+x1)/2 and (y1+y2)/2

7) (4+12)/2 = 8 and (9+-4)/2= 2.5

hence midpoint is (8,2.5)

8) we are told the midpoint so we can now find the co-ordinates of the other endpoint:

(5+x)/2= -3

rearrange to find x--> 5+x =-6, so x=-11

(-7+y)/2=2

rearrange to find y--> -7+y=4, so y=11

other endpoint: (-11,11)

5) the gradient of the new equation is parallel to y=3x+7 so it will stay the same

y=3x+c

we know that the points this line passes through is: (-4,-8) so we substitute this into our new equation to find c

-8= (3 x -4) +c

-8=-12 +c

so c= 4

Hence our new equation is y=3x+4

6) perpendicular gradient means that our existing gradient needs to be reciprocated (turned into negative and then flipped)

new gradient is -1/3

y=-1/3x+c

we know the value for x and y so we can substitute into our new equation to find c

9=(-1/3 x -6) +c

9=2 + c

c= 7

Hence our new equation is y=-1/3x+7

The relative extrema of the function  f(x) = x³ + 4x² - x - 4 is at

( [tex]-\frac{4+\sqrt{19}}{3} ,\frac{56+38\sqrt19}{27}[/tex] )and the graph of the function is attached below.

The given function is f(x) = x³ + 4x² - x - 4

For the relative extrema we will first have to find the first derivative of the function:

f'(x)  = 3x² + 8x - 1

Now for4 the function to have an extremum, f'(x) = 0

3x² + 8x - 1 = 0

Solving we get :

the values of x using the quadratic formula  are [tex](-\frac{4-\sqrt{19}}{3} , -\frac{4+\sqrt{19}}{3} )[/tex] .

Now we will substitute the values of x in the function f(x) to get the local extremum.

The maximum value of f(x) is [tex]\frac{56+38\sqrt19}{27}[/tex].

The minimum value of f(x) is [tex]\frac{56-38\sqrt19}{27}[/tex] .

Now we will use various points to find the values of f in the function.

At x = -3 , y = 8

At x = 0 , y = -4

At x =-1 , y = 0

Hence the relative extremum of the function is at [tex](-\frac{4+\sqrt{19}}{3} ,\frac{56+38\sqrt19}{27})[/tex] .

Regression

A) We can see the graph and through the data that the most indicated form is to find the regression model since there is not much uniformity among the data to describe it as a purely linear model.

Plotting that scatterplot, and generating the equation we know that the equation is:

Here, we want to evaluate the expression

We use the order of operations here PEDMAS ( parentheses, exponents (roots and powers) , division, multiplication, addition and subtraction)

We start out with the parentheses, then move on with the terms outside by multiplication

We have this as follows;

Answer:

A, B, F

Step-by-step explanation:

Well, to do this let's start by simplifying each of the ratios! If they can be simplified to 8:2 then they are a match

A: 16:4

Divide both sides by 2: 8:2 (This is an answer)

B: 40:10

Divide both sides by 5: 8:2 (This is also an answer)

C: 2:8

This one is not possible, because you would have to multiply the 2 by a whole number, and the 8 by a number less than one. Both have to be multiplied/divided by the same number.

D: 10:4

To get the 4 into a 2, we divide by 2. If we divide the 10 by 2 we get 5. Thus, this is not an answer.

E: 1:6

To get the 6 into a 2, we must divide it by 3. If we divide 1 by 3, we get a decimal, not 8.

F: 4:1

Multiply both sides by 2: 8:2 (This is our final answer)

The solution of the equation given as x/0.6= 9/0.5 is x= 10.8

The equation is given as

x/0.6= 9/0.5

There are no constants to add or subtract in the equation

So, we have

x/0.6= 9/0.5

Multiply through the equation by 0.6

This gives

0.6 * x/0.6= 9/0.5 * 0.6

Evaluate the products

0.6 * x/0.6= 10.8

Evaluate the products, again

x= 10.8

Hence, the solution is 10.8

Now, we can calculate b:

Now that we know the parameters m and b for the linear regression, we can build the equation:

Where x represents the murders and y the robberies per 100,000 population.

Then, (a): the equation of the regression line is y = 25.333x - 13.153.

To predict the robberies per 100,000 population when x = 4.5 murders, we just need to replace that 4.5 in the equation that we just found:

Finally, (b): according to the linear regression, the number of robberies per 100,000 population when x = 4.5 murders is approximately 100,85.
