Each half of the drawbridge is about 284 feet long. How high does the drawbridge rise when x is 30?? The drawbridge rises about
LuckyWell [14K]

Answer:

height = 142.00 ft

height ≈ 200. 82 ft

height ≈ 245.95 ft

Step-by-step explanation:

The picture below represent the image of the draw bridge. The illustration will form a right angle triangle. The hypotenuse is each half of the drawbridge which is 284 ft long. The opposite side  of the triangle is facing the drawbridge half leg and the adjacent side is horizontal length. This is the side that made the angle with the drawbridge half leg(hypotenuse).

The question ask us to find the height of the drawbridge when it rise which is the opposite sides of the triangle when the angle is 30° , 45° and  60°.

Using SOHCAHTOA principle,

Angle 30°

sin 30° = opposite/hypotenuse

sin 30°  = height/284

cross multiply

height = 0.5 × 284

height = 142.00 ft

Angle 45°

sin 45° = height/284

height = 284 × 0.70710678118

height = 200.818325857

height ≈ 200. 82 ft

Angle 60°

sin 60 = height/284

cross multiply

height = 0.86602540378  × 284

height = 245.951214675

height ≈ 245.95 ft

I SUCK AT MATH PLEASE HELP
sergeinik [125]

Answer:

1. -1/28

2. -4

3.A) The attendance increased by an average of 25 people per game from game 2 to game 5.

4. -.125

Step-by-step explanation:

To find the rate of change, we use the formula

f(x2) - f(x1)

--------------

x2-x1

1.  

f(x) = -(x) ^ 1/3

f(64) = -(64) ^ 1/3 = -4

f(8) =- (8)^1/3 = -2

f(64) - f(8)     -4--2             -4+2             -2            -1

-------------- = ---------     =  ------------- = ----------- =  ------

64 - 8              56               56              56            28

2.  

f(2) = 9

f(-2) = 25

f(x2) - f(x1)   f(2) - f(-2)      9-25              -16            -16

-------------- =----------- = ----------------- = ---------- = ----------- = -4

x2-x1             2--2                2+2              4            4

3.

f(5) = 755

f(2) = 680

f(x2) - f(x1)    f(5) - f(2)     755-680      75

-------------- = ----------   = -------------- = ---------- = 25

x2-x1              5-2                  3             3

A) The attendance increased by an average of 25 people per game from game 2 to game 5.

4.  

f(-1)  = -.25

f(1) = -.5

f(x2) - f(x1)    f(1) - f(-1)     -.5 --.25       -.5+.25     -.25

-------------- = ----------   = -------------- = ---------- = --------- = -.125

x2-x1              1--1                 1+1             2             2

One half the number of quarters Diane has
aev [14]
If you want to find half of how many of something divide that number by two. For example if Diane has 8 quarters that you would say 8÷2= 4. So half of the number of quarters Diane has would be 4. Here is another way to do it: You could also multiply 8 by 1/2. And 8•1/2 would be 4. I hope this helps!
