A boat drops an anchor 75 feet to the bottom of a lake. A sunken treasure chest lies at the bottom of the lake, 40 feet away fro

Reil [10]

Given
Height (length) of the anchor dropped from the boat = 75 feet
Distance of the treasure from the anchor = 40 feet

Solution
The dropped at the bottom makes an angle of 90 degree . Therefore making an right triangle with the chest and boat

By Pythagoras theorem
AC^2 = AB^2 + BC^2

(AC = distance of the treasure from the boat
AB = height of the anchor dropped from the boat
BC = the distance of treasure from the anchor)

AC^2 = 75^2 + 40^2
AC^2 = 5325 +1600
AC^2 = 6925
AC = 25 * (under root 11)

Therefore they have cover a distance of 25 * (under root 11)

5. Consider a cylindrical flowerpot with a radius 6 cm and a height of 11.5 cm. Calculate the lateral surface area of the painte

Nina [5.8K]

Answer: 660 cm²

Step-by-step explanation:

Surface area of a cylinder = 2πr² ± 2πrh = 2πr ( r + h )

π = 22/7

r = 6 cm

h = 11.5 cm

Lateral surface area = 2 x 22/7 x 6 ( 6 + 11.5 )

= 660 cm²

Use points (2001,17.60) and (2002,18.75) to write an equation in slope intercept form.

chubhunter [2.5K]

The general slope-intercept form is given by $y = mx + b$ , where $m$ is the slope and $b$ is the y-intercept.

Let's find the slope first. Remember that the slope given by two points is $\frac{y_2 - y_1}{x_2 - x_1}$ . So, using the two given points,

$m = \frac{y_2 - y_1}{x_2 - x_1}$
$m = \frac{18.75 - 17.60}{2002 - 2001}$
$m = 1.15$

Now, we know that $y = 1.15 x + b$ . To find $b$ , let's just plug in the x and y coordinates for one of the points and solve for b:

$17.60 = 1.15(2001) + b$
$17.60 = 2301.15 + b$
$b = -2283.55$

Thus, the equation of the line in slope-intercept form is

$\bf y = 1.15x - 2283.55$
