ladessa [460]

Answer:

The herd migrated a total of 43 3/10 miles and migrated about 14 13/30 miles a day.

Step-by-step explanation:

11 9/10 + 17 1/5 + 14 1/5 =

11 9/10 + 17 2/10 + 14 2/10 =

29 1/10 + 14 2/10 =

43 3/10

43 3/10 divided by 3/1 =

433/10 x 1/3 =

433/30 =

14 13/30

Under a dilation, the point (3,5) is moved to (6,10) What is the scale factor of the dilation?
nlexa [21]

The scale factor of the dilation is 2.

Option D is correct.

Step-by-step explanation:

To find the scale factor of dilation, we find ratio of similar sides.

We are given  the point (3,5) is moved to (6,10) under dilation.

Scale Factor = 6/3 = 2

or

Scale Factor = 10/5 = 2

The scale factor of the dilation is 2.

Option D is correct.

Keywords: scale factor of the dilation

Having trouble with this one can someone teach me how to find the slope in this question. Try to help me learn it aswell. Its in
ASHA 777 [7]
Hi there! The answer is -2.

We can find the slope of a formula by using the following formula:

slope = \frac{change \: of \: y}{change \: of \: x} =\frac{y2 - y1}{x2 - x1}
x2 and y2 don't mean squared, but the x and y coordinate of our second point.

First we need to find two points on the line. Ijn this particular case we have (-3, 3) and (1, -5). Now we can fill in the formula.

slope = \frac{ - 5 - 3}{1 - - 3} = \frac{ - 8}{4} = - 2

Therefore, the third answer is correct.
~ Hope this helps you!

Use f’( x ) = lim With h ---> 0 [f( x + h ) - f ( x )]/h to find the derivative at x for the given function. 5-x²
beks73 [17]
<h2>Answer:</h2>

The derivative of the function f(x) is:

                 f'(x)=-2x

<h2>Step-by-step explanation:</h2>

We are given a function f(x) as:

f(x)=5-x^2

We have:

f(x+h)=5-(x+h)^2\\\\i.e.\\\\f(x+h)=5-(x^2+h^2+2xh)

( Since,

(a+b)^2=a^2+b^2+2ab )

Hence, we get:

f(x+h)=5-x^2-h^2-2xh

Also, by using the definition of f'(x) i.e.

f'(x)= \lim_{h \to 0} \dfrac{f(x+h)-f(x)}{h}

Hence, on putting the value in the formula:

f'(x)= \lim_{h \to 0} \dfrac{5-x^2-h^2-2xh-(5-x^2)}{h}\\\\\\f'(x)=\lim_{h \to 0} \dfrac{5-x^2-h^2-2xh-5+x^2}{h}\\\\i.e.\\\\f'(x)=\lim_{h \to 0} \dfrac{-h^2-2xh}{h}\\\\f'(x)=\lim_{h \to 0} \dfrac{-h^2}{h}+\dfrac{-2xh}{h}\\\\f'(x)=\lim_{h \to 0} -h-2x\\\\i.e.\ on\ putting\ the\ limit\ we\ obtain:\\\\f'(x)=-2x

      Hence, the derivative of the function f(x) is:

          f'(x)=-2x
