Limx²-9x+20 x->4 x-4?

Gala2k [10]

Answer:

-1

Step-by-step explanation:

lim x tends to 4 (x^2-9x+20)/(x-4). (x^2-9x+20)(x-4)=x-5.

So the limit is 4-5=-1

Write the equation of the circle that has a center of (-7, 17) with a radius of V19.

kipiarov [429]

I think your question seems to be :-

Write the equation of the circle that has a center of (-7, 17) with a radius of √19

So , as we know that the equation of circle with centre at (h,k) and radius r is given by ${\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}$ . Now , using same concept in this question ;

${:\implies \quad \sf \{x-(-7)\}^{2}+(y-17)^{2}=(\sqrt{19})^{2}}$

${:\implies \quad \bf \therefore \quad \underline{\underline{(x+7)^{2}+(y-17)^{2}=19}}}$

This is the required equation of Circle

m=(-7-(-19))/(-2-1)

m=(-7+19)/-3

m=12/-3

m=-4

An exponential relationship has a growth factor of3and y-intercept of 4.Evalute the function that represents the function that r

Murrr4er [49]

Answer:

$f(10)= 236196$

Step-by-step explanation:

Given

$(x,y) = (0,4)$ --- y intercept

$b = 3$ --- growth factor

Required

$f(10)$

An exponential function is represented as:

$y = ab^x$

$(x,y) = (0,4)$ means

$4=a * b^0$

$4=a *1$

$a= 4$

So, we have:

$y = ab^x$

$y = 4(3)^x$

$f(x)= 4(3)^x$

When x is 10, the value of the function is:

$f(x)= 4(3)^x$

$f(10)= 4(3)^{10$

$f(10)= 236196$
