Gradient = change in y /change in x so -6-2 =-8 / -16-4 = -20 so -8/-20 = 0.4 so gradient = 0.4

Which function transforms the graph of y= x^2 so that it is first shifted down 4 units and its then reflected across the y- axis

GaryK [48]

Answer:

Option C. y= ( -x)^2 -4

Step-by-step explanation:

If we have a function $f(x) = ax ^ 2$ and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:

$g(x) = f(x) -c$

In this case we want to move the function 4 units down, then:

$g(x) = f(x) -4\\\\g(x) = x ^ 2 -4$

Finally, to reflect the function on the y-axis. must do $y = g(-x)$

Then we have the following function:

$g(-x) = (-x) ^ 2 -4\\\\y = (-x) ^ 2 -4$

The answer is option C

Likurg_2 [28]

Answer:

44.8

Step-by-step explanation:

cos α = adjacent leg/hypotenuse

cos 48° = 30/x

x = 30/(cos 48°) = 44.8

A class of 25 students is going on a field trip to a science museum.They plan to visit the exhibits in small groups of 2,3, or 4

Andreyy89

The least number of chaperones they will need is 5 chaperones because the greatest amount of students in a group is 4, so less chaperones. If each group has one chaperone that is 5 people per group total. 25 divided by 5 is 5.
