The difference quotient of the function that has been presented to us will turn out to be 5.

<h3>How can I calculate the quotient of differences?</h3>

In this step, we wish to determine the difference quotient for the function that was supplied.

To begin, keep in mind that the difference quotient may be calculated by:

Lim h->0 $\frac{f(x+h)-f(x)}{h}$

Now, for the purpose of the function, we need this:

Then we will have:

$\begin{aligned}&\lim _{h \rightarrow 0} \frac{j(x+h)-j(x)}{h} \\&\lim _{h \rightarrow 0} \frac{5 *(x+h)-3-5 * x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 x+5 h-3-5 x+3}{h} \\&\lim _{h \rightarrow 0} \frac{5 h}{h}=5\end{aligned}$

j(x) = 5x - 3

Then the following will be true:

Therefore, 5 is the value of the difference quotient for j(x) is %

What does he mean on question one

Katarina [22]

You plug -2 in for the function k(p) and add it to the function g(w), getting
(-2+3)*(-2-7)+(-2-5)^2=1*-9+49=40 for a - I challenge you to do B on your own!

Determine the remainder when (5x3 + 49x2 + 74x + 6) is divided by (x + 8).

blondinia [14]

The polynomial remainder theorem says that the remainder when dividing a polynomial $P(x)$ by a linear divisor $x-k$ is simply $P(k)$ .

If $P(x)=5x^3+49x^2+74x+6$ , then the remainder upon dividing by $x+8$ is

$P(-8)=-10$

You could also verify this by actually computing the quotient and remainder.

Determine the standard form of the equation for the circle with center (h,k) = (-5 ½) and radius r =1

wariber [46]

Asuuing yo meant (h,k)=(-5,1/2)

equation is $(x-h)^2+(y-k)^2=r^2$
(h,k) is center and r=radious
given that (h,k)=(-5,1/2) and r=1
h=-5
k=1/2

$(x-(-5))^2+(y- \frac{1}{2} )^2=1^2$
$(x+5)^2+(y- \frac{1}{2} )^2=1$
if you wanted us to expand
x²+y^2+10x-y+25.25=1
