Answer:

1

Step-by-step explanation:

<h2>Given, y = b m x m</h2><h2>y' = -b m x (m+1)</h2><h2>At any point (x1,y1)</h2><h2 /><h2>Equation of tangent is given by </h2><h2>y - y1 </h2><h2>------- = -b m x1 -(m+1)</h2><h2>x - x1</h2><h2>Y intercept = - m</h2><h2>X intercept = (m-1) × 1</h2><h2> m </h2><h2>Area bounced = 1 (m - 1)×1</h2><h2> ---- ---------------------- x m</h2><h2> 2 m</h2><h2>For area to be constant, m = 1</h2>

What value for C will make the expression a perfect square trinomial x2-7x+c

Tom [10]

Answer:

The value of c is 12.25

Step-by-step explanation:

we know that

A perfect square trinomial is of the form

$(x-a)^{2}=x^{2}-2ax+a^{2}$

In this problem we have

$x^{2}-7x+c$

so

equate the equations

$x^{2}-7x+c=x^{2}-2ax+a^{2}$

we have

the following equations

$-7x=-2ax$ -----> equation A

and

$c=a^{2}$ -----> equation B

<u>Solve the equation A</u>

$-7x=-2ax$

$7=2a$

$a=3.5$

<u>Solve the equation B</u>

$c=a^{2}$

$c=3.5^{2}=12.25$

therefore

$(x-3.5)^{2}=x^{2}-7x+12.25$

The value of c is 12.25

F(x)=5x^4 helllllpppppp

Marina CMI [18]

we can use properties of functions to find this out

for $f(x)=ax^b$

if b is even, then the ends of the function go in the same directions (both up or both down)

if b is odd, then the ends of the function go in different directions (one up and one down)

if a is positive and b is even, then both ends point up

if a is positve and b is odd, then it goes from bottom left to top right

if a is negative and b is even, then both ends point down

if a is negative and b is odd, then it goes from top left to bottom right

given $f(x)=5x^4$

a=5>0

b=4 which is even

so it has both ends pointing up
