Which quadratic equation fits the data in the table? (PICTURE OF TABLE ATTACHED)
Paha777 [63]
The correct quadratic equation for that set of points is:
y=x^2+7x+1

To check it, simply put first and last pair of points and assure the equality:
-11=(-3)^2+7*(-3)+1
-11=9-21+1
-11=-11

79=6^2+7*6+1
79=36+42+1
79=79

To find the equation of a line, we need the slope of the line and a point on the line. Since we are requested to find the equati
murzikaleks [220]

Answer:

x-4y+4=0

f(x)=\sqrt x and x=4

Step-by-step explanation:

We are given that a curve

y=\sqrt x

We have to find the equation of tangent at point (4,2) on the given curve.

Let y=f(x)

Differentiate w.r.t x

f'(x)=\frac{dy}{dx}=\frac{1}{2\sqrt x}

By using the formula \frac{d(\sqrt x)}{dx}=\frac{1}{2\sqrt x}

Substitute x=4

Slope of tangent

m=f'(x)=\frac{1}{2\sqrt 4}=\frac{1}{2\times 2}=\frac{1}{4}

In given question

m=\lim_{x\rightarrow a}\frac{f(x)-f(a)}{x-a}

\frac{1}{4}=\lim_{x\rightarrow 4}\frac{f(x)-f(4)}{x-4}

By comparing we get a=4

Point-slope form

y-y_1=m(x-x_1)

Using the formula

The equation of tangent at point (4,2)

y-2=\frac{1}{4}(x-4)

4y-8=x-4

x-4y-4+8=0

x-4y+4=0

What is 7.0717 million in figures. ?
Brrunno [24]

7.0717 million

Lets see:

1 million = 1.000.000

So, 7.0717 million = 7.071.700

7.071.700 can be read as "seven million seventy one thousand and seven hunred"

If you wanna split it you can split in

seven million = 7 million

seventy one thousand = 71 thousand

seven hundred = 7 hundred
