ANSWER

x =  \pm5\sqrt{2}

EXPLANATION

The given equation is:

50 -  {x}^{2}  = 0

Group the constant term to get:

-  {x}^{2}  = 0 - 50

- {x}^{2}=- 50

{x}^{2}=50

Take square root to get:

x =  \pm \sqrt{50}

We simplify further to remove the perfect square.

x =  \pm \sqrt{25 \times 2}

x =  \pm \sqrt{25} \times  \sqrt{2}

x =  \pm5\sqrt{2}

Triangles ABC and EDC are outlined on a bridge. The triangles share vertex C and angles D and B are right angles. A new bridge s
dexar [7]

CHECK THE ATTACHED FIQURE FOR THE BRIDGE

Answer:

60 ft

Step-by-step explanation:

From the question we know that triangles ABC and EDC are in a 1:1 with this given ratio it implies that

triangles ABC and EDC are congruent then we can say

side EC = side AC

3x + 9 = 5x - 5

Then we can simplify to know value of x

3x + 14= 5x

2x = 14

x = 7

But we know that AC= 5x - 5 , then substitute value of x into it

AC = 5x + 5 = 5(7) - 5

= 35 - 5

AC= 30 ft

Also EC= 3x + 9 then substitute value of x into it

EC = 3x + 9 = 3(7) + 9

= 21 + 9

EC= 30 ft

Then the the distance between the top and bottom of the bridge, in feet, = EC+AC

= 30 + 30 = 60 ft

Show that cos2x=cosx
PSYCHO15rus [73]

cos (2x) = cos x

2 cos^2 x -1 = cos x   using the double angle formula

2 cos ^2 x -cos x -1 =0

factor

(2 cos x+1) ( cos x -1) = 0

using the zero product property

2 cos x+1 =0    cos x -1 =0

2 cos x = -1       cos x =1

cos x = -1/2       cos x=1

taking the arccos of each side

arccos cos x = arccos (-1/2)         arccos cos x = arccos 1

x = 120 degrees   x=-120   degrees           x=0

remember you get 2 values ( 2nd and 3rd quadrant)

these are the principal values

now we need to add 360

x = 120+ 360n      x=-120+ 360n      x = 0 + 360n  where n is an integer

If VZ=p–7 and WY=p–21, what is the value of p?
sveta [45]

Using the midline property;

2wy = vz

2(p - 21) = p - 7

2p - 42 = p - 7

2p - p =  - 7 + 42

p = 35

The sum of two numbers is 30. the first number is 1/5 of the second number. what are the numbers?
bonufazy [111]
Same question
x+y=30
x is 1/5 of y
x=y/5
subsitute
y/5+y=30
multily both sidse by 5
y+5y=150
add
6y=150
divide both sides by 6
y=25
subsitute
x=y/5
x=25/5
x=5
the numbers are 5 and 25
