(h(1) = 96<br> (h(n) = h(n − 1) - 1<br> Find an explicit formula for h(n).
Lubov Fominskaja [6]

Answer:

a_n=97-n

Step-by-step explanation:

Given:

h(1)=96\\ \\h(n)=h(n-1)-1

Find first terms:

h(1)=96\\ \\h(2)=h(2-1)-1=h(1)-1=96-1=95\\ \\h(3)=h(3-1)-1=h(2)-1=95-1=94\\ \\h(4)=h(4-1)-1=h(3)-1=94-1=93\\ \\....

In this arithmatic sequence, each next term is 1 less than the previous term.

The general explicit formula is

a_n=a_1+(n-1)d

In your case,

a_1=96\ \text{   First term}\\ \\d=-1\ \text{   Common difference}

Then

a_n=96+(n-1)\cdot (-1)\\ \\a_n=96-(n-1)\\ \\a_n=96-n+1\\ \\a_n=97-n

A line segment has the endpoints (2 -5) and (-1 -1) what is its slope?
Ganezh [65]
I believe,
since... slope = (y2-y1)/(x2-x1)
so... slope = (-1+5)/(-1-2)
slope = (4)/(-3) or.. -.75

Write in the slope intercept form an equation of the line that passed through the given points.
lutik1710 [3]

Answer:

y=3x+4

Step-by-step explanation:

first you find the slope by doing change in y over change in x. The change in y is 9 because 7-(-2)=9. The change in x is 3 because 1-(-2)=3. Then you do 9/3 which is 3, which is your slope, or m.

So now you know y=3x+b, then you substitute one of the points in for x and y, and you get 7=3(1)+b, where b is your y-intercept. then you solve, and find that b=4.

Now you put it into slope intercept form, which is y=mx+b, where m=3 and b=4, so you are left with y=3x+4.

Leave a thanks if I am correct please.

Find the vertex and axis of symmetry of each quadratic equation.
icang [17]

Answer: Vertex (-2,-15) and therefore the axis of sym will be -2

Step-by-step explanation: Using -b/2a you can deduce that 4x^2 is a, 16x is b and 1 is c. So -b/2a = -16/8 = -2. Then you plug -2 for y and yu should get -15. Then x will be your axis of symetry to x=-2
