Find the coordinates of the orthocenter of abc. a(-1,0) b(0,4) c(3,0)

Step-by-step explanation:

Hi there!

1) Firstly, connect the points to draw a triangle.

2) From each vertex either with a pair of square or with a software trace a perpendicular line to the opposite side.

3) The concurrent point, i.e. the intersection point of these three altitudes is the orthocenter. Orthocenter means the the right center.

In equilateral triangles the Orthocenter coincides with the Centroid.

4) Finally, the coordinates of the Orthocenter found is (0,0.75)

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

6 and 24

step-by-step explanation:

6 x 4 = 24
