const2013 [10]4 years ago
5 0

Answer:

P = 0.05

Step-by-step explanation:

E = P4πr²

2.50 = P4π(2)²

2.50 = P4π4

2.50 = P(50.265)

P = 0.05

Find the equation of the line in slope-intercept form containing the points (4,6) and (9,16).
inna [77]

Hello!

Slope-intercept form is y = mx + b. In this form, m is the slope and y is the y-intercept.

To find the slope, we need to use the slope formula. The slope formula is: \frac{y_{2}-y_{1} }{x_{2}-x_{1}}. We can assign the point (4, 6) to x_{1} and y_{1} and (9, 16) to x_{2} and y_{2}.

Now, we can find the slope: \frac{16-6}{9-4} = \frac{10}{5} = 2

Next, we can find the y-intercept by substituting a point into the slope-intercept form with the slope as 2.

y = 2x + b (substitute a given point)

6 = 2(4) + b (simplify)

6 = 8 + b (subtract 8 from both sides)

-2 = b

Therefore, the equation of the line is y = 2x - 2.

A map using a scale inch of 1 to 5 miles shows a section of land with an area of 3.2 in.² what is the actual area of the section
Karolina [17]

Answer:

The actual area of land is 80 mi² .

Step-by-step explanation:

Given that we have to find the actual area so first we have to square the ratio(scale factor) :

1 in : 5 mi

(1 in)² : (5 mi)²

1 in² : 25 mi²

Next, the actual area will be :

1 in² = 25 mi²

(1 × 3.2) in² = (25 × 3.2) mi²

3.2 in² = 80 mi²
