At a point on the ground 35 ft from the base of a tree, the distance to the top of the tree is 1 ft more than 3 times the height
jolli1 [7]

Answer:

Step-by-step explanation:

This is a question that uses the Pythagorean Theorem.

a = 35 feet

b = x            which is the height of the tree.

c = 3*x + 1   so we are trying to find x.  Substitute into a b and c

a^2 + b^2 = c^2

35^2 + x^2 = (3x + 1)^2        

35^2 + x^2 = 9x^2 + 6x + 1     Subtract x^2 from both sides.

35^2 = 8x^2 + 6x + 1               Subtract 35^2 from both sides.

0 = 8x^2 + 6x + 1 - 35^2

0 = 8x^2 + 6x - 1224

Does this factor?

(x + 12.75)(x - 12)

x - 12 = 0 is the only value that works.

x = 12

The tree is 12 feet high.

Note: I used the quadratic formula to solve this.

Please help mee , i will marl the brainliest .
Tcecarenko [31]

Answer:

n = - 6

Step-by-step explanation:

Given k(x) then k(x) + n is a vertical translation of k(x)

• If n > 0 then a shift up of n units

• If n < 0 then a shift down of n units

Here k(x) has been shifted from (0, 0 ) to (0, - 6 )

That is a shift down of 6 units, then

p(x) = k(x) - 6

That is n = - 6

Find the equation of a line that passes through the points (-1,3) and (3,5).
vekshin1

Answer:

y=1/2x+3.5

Step-by-step explanation:

this one was a bit trickier than the previous one, but i think that that answer is correct. i did the same thing i did to solve your last problem, solved for the slope, and then made a number line and marked the points given, drew a line through the two points, and found where the line intercepted the y axis.
