Brett is 75 feet from the base of a building. he measures the angle of elevation to the top of the building and records it as 80
SashulF [63]
This is the concept of trigonometry, we are required to calculate the number of floors the building has given the information above;
# floors=[height of the building]/[height of each floor]
height of each floor=17 ft
let the height of the building be,h.
h is given by;
tan theta=opposite/adjacent
theta=80
opposite=h
adjacent=75 ft
thus
tan 80=h/75
h=75 tan 80
h=425.35 ft
thus the number of floors will be:
425.35/17
=25.020≈25 floors

Which equation represents a line that passes through (4, left-parenthesis 4, StartFraction one-third EndFraction right-parenthes
Alina [70]

Answer:

y-\frac{1}{3}=\frac{3}{4}(x-4)

Step-by-step explanation:

we know that

The equation of the line into point slope form is equal to

y-y1=m(x-x1)

In this problem we have

point\ (4,\frac{1}{3})

m=\frac{3}{4}

substitute the given values

y-\frac{1}{3}=\frac{3}{4}(x-4)

y minus StartFraction one-third EndFraction equals StartFraction 3 Over 4 EndFraction left-parenthesis x minus 4 right-parenthesis.(x – 4)

Solve 2x2 + x − 4 = 0.<br><br><br> x^2 + ____x+____ = 0
alisha [4.7K]

Kate: Please, for clarity, use " ^ " to denote exponentiation: 2x^2 + x − 4 = 0


And please include the instructions.


2x^2 + x − 4 = 0 can be re-written: 2(x^2 + (1/2)x - 2) = 0


Dividing both sides by 2 results in x^2 + (1/2)x - 2 = 0


Let's "complete the square:" x^2 + (1/2)x + (1/4)^2 - (1/4)^2 = 0


Then (x+(1/4))^2 = (1/4)^2


Taking the sqrt of both sides: x+1/4 = plus or minus 1/4


Solving for x: x = -1/4 plus or minus 1/4


Solving for x (continued): x = 0 and x = -1/2
