Answer:
x =3
Step-by-step explanation:
The axis of symmetry is at the vertex
The x coordinate gives the axis of symmetry
x =3
Answer:
The response that are true are:
- linear function has a constant additive rate of change, while a nonlinear function does not.
Since in linear function the rate of change is always equal as for a linear function we get a equation of line such that the slope is same.
- On a graph, the function must be a straight line to be linear.
Liner means there is a straight line of the function.
( Also it need not be true that the independent variable increases by 1.
There may be change of some other quantity in independent variable )
Answer: 41
Step-by-step explanation:
9*(-2)*(-2) - 4*(-2) - 3 = 9*4 + 8 - 3 = 36 + 5 = 41
By using trigonometric relations, we will see that:
AC = 15.6 in
AB = 8.4 in.

How to get the measures of the other two sides of the right triangle?</h3>
Here we have the right triangle where:
B = 90°
C = 40°
BC = 10 in.
Notice that is the adjacent cathetus to the angle C, then we can use the two relations:
- sin(a) = (adjacent cathetus)/(hypotenuse).
- tan(a) = (opposite cathetus)/(adjacent cathetus).
Where:
- hypotenuse = AC
- opposite cathetus = AB.
Then we will have:
sin(40°) = 10in/AC.
AC = 10in/sin(40°) = 15.6 in
tan(40°) = AB/10in
tan(40°)*10in = AB = 8.4 in.
So we can conclude that for the given right triangle we have:
AC = 15.6 in
AB = 8.4 in.
