Answer:

$\sqrt{29}$

Step-by-step explanation:

Use the distance formula. $\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

Plug in the coordinates into the equation. $\sqrt{(2-0)^{2}+(5-0)^{2}}$

Solve the distance formula. $\sqrt{(2)^{2}+(5)^{2}}$ --> $\sqrt{4+25}$ --> $\sqrt{29}$

Answer:

Use the formula for the distance between two points: d = √((x2 – x1)2 + (y2 – y12))

Step-by-step explanation:

d = √((5 – 0)2 + (2 – 0)2

d = √(25 + 4) = √(29) ≈ 5.385

Maurinko [17]

Answer:

262

Step-by-step explanation:

From the Question, we know that:

In a certain town there were 403 robberies last year. This year the number of robberies has gone down 35%.

Step 1

Find the amount decreased

35% × 403

= 35/100 × 403

= 141.05

Step 2

The amount of robberies this year is:

= 403 - 141.05

= 261.95

Approximately to the nearest whole number = 262

Use the equation m Subscript PQ Baseline equals StartFraction f left parenthesis x 1 plus h right parenthesis minus f left paren

babunello [35]

Answer:

m = 12

Step-by-step explanation:

For f(x) = 2x² you want to find the slope m using ...

m = (f(x+h) -f(x))/h

at x=3.

Filling in the function definition and its arguments, we have ...

m = (2(x+h)² -2x²)/h = (2x² +4hx +2h² -2x²)/h = 4x +2h

The value of this as h goes to zero is ...

m = 4x

At x=3, the slope is ...

m = 4·3 = 12

_____

The attached graph shows a numerical estimate of the slope (f'(3)=12) and the line with that slope through the point P(3, 18). The line certainly appears to be tangent to the curve at that point.
