a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is

ANTONII [103]

Answer:

$(y-30)=2(x-10)$

Step-by-step explanation:

We have been given that a bean plant grows at a constant rate for a month. after 10 days, the plant is 30 centimeters tall. after 20 days, the plant is 50 centimeters tall.

First of all we will find slope of our line using given points.

$m=\frac{y_2-y_1}{x_2-x_1}$

Upon substituting coordinates of our given points in slope formula we will get,

$m=\frac{50-30}{20-10}$

$m=\frac{20}{10}=2$

Therefore, slope of our given line is 2.

Since the equation of a line in point slope form is $(y-y_1)=m(x-x_1)$ .

Upon substituting m=2 and coordinates of one point in above equation we will get,

$(y-30)=2(x-10)$

Therefore, the equation that models the height of the plant (y) after x days will be $(y-30)=2(x-10)$ .

Find the lateral area of the regular prism with height h , if the base of the prism is: Equilateral triangle with the side 4 cm

Nina [5.8K]

Answer:

the lateral area of the regular prism is 30 cm².

Step-by-step explanation:

Given;

the base of the regular prism, b 4cm

height of the prism, h = 2.5 cm

The lateral area of the regular prism is calculated as the product of the base perimeter and height of the prism.

L.A = P x h

where;

P is the perimeter of the base = 3 x 4cm (equilateral triangle has equal sides)

P = 12 cm

L.A = 12 cm x 2.5 cm

L.A = 30 cm²

Therefore, the lateral area of the regular prism is 30 cm².

Make a shaded graph with inequality 3x + y > 4.

Lelechka [254]

9514 1404 393

Answer:

see attached

Step-by-step explanation:

The equation can be written in slope-intercept form as ...

y > -3x +4

The dashed boundary line has a y-intercept of (0, 4) and a slope of -3. Shading is where x-values and y-values are greater than those on the boundary line, so will be to the right and above the line.
