Determine whether each function is an example of exponential growth or decay. Then, find the y -intercept. y=0.5(1/4) x

4x you had  0.5x are the y -intercept.

How can you tell whether an exponential function is growing or deteriorating?

  • As the exponential's base is greater than 1, which occurs when those numbers increase, we are seeing exponential growth.
  • When the exponential's base is between 1 and 0, and those numbers decrease, we have exponential decay.

You can obviously plot it but if you can also conside that in your function you have 4x

; this tells you that as

x increases (gets bigger) certainly

4x will increase as well (you can consider

4²= 16 and 4³ = 64

). It is true that you have to multiply by

0.5

but nevertheless the entire function will grow anyway!

Graphically:

graph{0.5*(4^x) [-14.24, 14.24, -7.12, 7.12]}

If you want, try to think at the case where instead of having

4x you had  0.5x .

Simplify the expression by combining like terms: x + 7x
Aneli [31]

Answer:

Like terms means that the numbers have the same variable after them or they don't have a variable at all.  It is also important to remember that any letter that doesn't have a number in front of it technically has a 1 in front of it.

For example, x + 3x = 1x +3x.  Then I add the numbers in the front and I get 4x.

If it had been 4x + 7x + 3, my answer would have been 11x +3.  That's because there were a total of 11 x, but the 3 ones weren't x's so I just leave them alone.

The figure shows a circle circumscribed around a triangle.
e-lub [12.9K]

Option B is right perpendicular bisectors of the sides of the triangle

<h3>What circumcircle?</h3>

If we draw a circle through all the vertices of a triangle then the circle obtained is the circumcircle of the given triangle. We have in a triangle there are some properties inherent.

One is the perpendicular bisectors of all sides are concurrent. These three concur at a point called the circumcentre of the triangle.

When we draw a perpendicular bisector for a side AB, we get that all points on the perpendicular bisector are equidistant from A and B.

When we take the point of intersection of the perpendicular bisector of AB and BC, we have the intersecting point S(say) is equidistant from A and B and also from B and C

In short, this is equidistant from all 3 vertices and hence is the centre of the circumcircle of triangle ABC

Therefore Option B is right perpendicular bisectors of the sides of the triangle.
