An architect is standing 250 feet from the base of a building and would like to know the height of the building. If he measures

the angle of elevation to be 55°, what is the approximate height of the building? Round any intermediate calculations if needed to know less than six decimal places and round the final answer to the nearest 10th of a foot

see the figure below to better understand the problem

we have that

\begin{gathered} tan55^o=\frac{h}{250}---->\text{ by TOA} \\  \\ solve\text{ for h} \\ h=250*tan55^o \\ h=357.0\text{ ft} \end{gathered}<h2>The answer is 357.0 feet</h2>

Answer:

8.  (0,-2)

9. (-2,1)

Step-by-step explanation:

Lucy's house is at (1,1)

Down means in the y coordinate , left means negative x

Down 3 means subtract 3 from y

left 1 means subtract 3 from x

(1-1, 1-3)

(0,-2)

9. Lucy is at (1,1)

3 units to the left

left means subtract 3 from x

(1-3, 1)

F(x)=lx+4l+3 how do u do it
dybincka [34]

Answer:

implifying

f(x) = lx + 4l + -3

Multiply f * x

fx = lx + 4l + -3

Reorder the terms:

fx = -3 + 4l + lx

Solving

fx = -3 + 4l + lx

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -3x-1 + 4lx-1 + l

Simplifying

f = -3x-1 + 4lx-1 + l

Reorder the terms:

f = l + 4lx-1 + -3x-1

Please help for Q4 I’m super lost. Write an expression for the sum of four consecutive odd numbers where 2n+1 is the smallest od
sveta [45]

Answer:

n+2

Step-by-step explanation:

This is a Typical Question on Arithmetic Progression with initial term as 2n+1

The next number in this particular series will be 2n+1+2 which is 2n+3 and so on. Thus a common difference of 2 exists.

The nth term of an Arithmetic Progression AP, bn is represented below where b1 is the first term

bn=b1 +(n-1)d where d is the common difference

For this particular series, the 4th term b4 is

b4= 2n+1+(4-1)2 0r b4 =2n+1+6=2n+7

sum of series is represented by equation: n(b1 +b4)/2 where b1 and b4 are 1st and 4th term respectively

Thus Sum required =4(2n+1+2n+7)/2=4(4n+8)/2=8n+16  0r n+2
