Answer:

   0.0056

Step-by-step explanation:

  f(x) = √(49 +x)

  f'(x) = 1/(2√(49 +x))

A linear approximation of f(x) expanded about x=0 is ...

  f(x) ≈ f(0) + f'(0)x = 7 +x/(2·7)

Then for √53, we have x=4

  f(4) ≈ 7 +4/14 = 7 2/7 . . . . . approximate √53 using differentials

__

The calculator value of √53 is about 7.280110, so the difference in results is ...

  approx - actual ≈ 7.285714 -7.280110 = 0.005604 ≈ 0.0056

50× 3/8 how to reduce answer to lowest te
hoa [83]

The lowest term is \frac{75}{4}.

Solution:

Given expression is 50\times\frac{3}{8}

<u>To reduce this term to the lowest term:</u>

$50\times\frac{3}{8}=\frac{50}{1}\times\frac{3}{8}

Multiply the numerator and denominator.

$50\times\frac{3}{8}=\frac{150}{8}

Now, divide the numerator and denominator by the greatest common factor.

Here 150 and 8 both have common factor 2.

So, divide numerator and denominator by 2.

           $=\frac{150\div2}{8\div2}

           $=\frac{75}{4}

$50\times\frac{3}{8}=\frac{75}{4}

Hence the lowest term is \frac{75}{4}.

Y=0.5x how do you work it
photoshop1234 [79]
Plug any number in for x and find the resulting y, then if you need to graph place the coordinate points on the plane. For example if you set x=2 the equation becomes y=0.5(2). From here we can see 0.5(2)=1 and this is equal to 1 so in a data chart you would write under x the number 1 and under y the number 2.

Which equation could represent the relationship shown in the scatter plot?
KonstantinChe [14]
Choice D : look at where you think the line would be if it followed the direction of the data so that about half of the points fell above the line and half below. The two most important things to note are the slope of the line and y intercept.
This is a negative relationship as the line falls as you read it from left to right. That eliminates choice C. Next, it appears the line of best fit would have a y intercept around 10 on the y axis and then fall down and to the right cutting the data. Note that choices A and B have y intercepts that don't make sense for the data. Choice D does have a y intercept of 10 and a negative slope.
