1: Plot the graph of the equation 2x-3y=6 and 2x+y=-10 and intercept the result.

Vladimir [108]

To graph the equations, rewrite the equations written in standard form to slope-intercept form of the equation.

$y=mx+b\\\\ 2x-3y=6\\ 2x+y=-10 \\\\3y= 2x- 6\ \ / :3\\ y=-2x-10 \\\\y= \frac{2}{3}x- 2 \\ y=-2x-10$

$Answer : \\ \\The \ lines \ intersect \ when \ x = -3 \ and \ y = -4$

A soup bowl is in the shape of a hemisphere with a diameter of 10 cm. What is the approximate maximum volume of soup that the bo

Oduvanchick [21]

Answer:

3.48cm³ (approximated)

Step-by-step explanation:

The maximum water that bowl can hold = The volume of the bowl

$\boxed{ \mathsf{volume \: of \: bowl = \frac{2}{3} \times \pi \: r {}^{3} }}$

Radius is half of diameter.

Given -

Diameter = 10cm .

From the given data we can derive that the radius of the hemispherical bowl is 5cm (10/2)

Putting the known values into the formula to get the value of the volume of bowl :

$\mathsf{volume = \frac{2}{3} \times \: 3.14 \: \times {5}^{3} }$

= 3.48888cm³

= 3.48cm³
