Line t intersects the line given by y=4x-2 at the point (4,14) to form a right angle. Which is the equation of line t
Aliun [14]

Answer:

y = -1/4 x + 15.

Step-by-step explanation:

y = 4x - 2 has a slope of 4 ( = the coefficient of x).

The line  at right angles to it will therefore of a slope of -1/4.

Using the point-slope form of a line the line t which passes through (4, 14) is found as follows:

y - 14 = -1/4(x - 4)

y = -1/4x + 1 + 14

y = -1/4x + 15

PLEASE HELP ME: ASAP
VashaNatasha [74]

Ok so

Corresponding sides and angles are a pair of matching angles or sides that are in the same spot in two different shapes.

It would basically be a ratio (7:14)

My best help would be this

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides. This proves that the ratio of areas of two similar triangles is proportional to the squares of the corresponding sides of both the triangles.

I really hope this helps, dont have a lot of time today to answer a lot of questions so have a great day and lmk if this helps!

Identify the absolute extrema of the function and the x-values where they occur.
sladkih [1.3K]
f(x)=6x+\dfrac{24}{x^2}+3\\&#10;f'(x)=6-\dfrac{48}{x^3}\\&#10;6-\dfrac{48}{x^3}=0\\&#10;6x^3-48=0\\&#10;6x^3=48\\&#10;x^3=8\\&#10;x=2\\&#10;

For x the derivative is negative.
For x>2 the derivative is positive.
Therefore at x=2 there's a minimum.

f_{min}=6\cdot2+\dfrac{24}{2^2}+3=12+6+3=21
