Answer:

a=9, c=19

Step-by-step explanation:

Aight so basically in 30, 60, 90 triangles there is a formula for the sides

the hypotenuse(the longest side)=2a

The tiny side (the smallest side)=a

and the middle child =a\sqrt{3}

Based on that we see that a is 9

and since c=2a then it's 18

Amelie solves the following system of equations.
PIT_PIT [208]

The values of x and y that satisfy this system of equations are 10 and 5 respectively

<h3>Simultaneous equation</h3>

Given the system of equations

x + y = 20

3x - 3y = 30

_____________________

x + y = 20

x - y = 10

Add the equations

2x = 20 + 10

2x = 30

x = 30/2

x = 15

Substitute

x -y = 10

15 - y = 10

y = 5

Hence the values of x and y that satisfy this system of equations are 10 and 5 respectively

Please help I will give brainliest to the right answer!!!
timama [110]

Answer:

Step-by-step explanation:

Given function l:

h= -16t² + 26t

where h represents height and t represents time.

The time for dolphin atbthe height 5 feet is given by putting the value of h as 5 in the function,

5 = -16t² + 26t

16t² - 26t + 5 = 0

For this equation: a=16, b=-26, c=5

Use quadratic formula with a=16, b=-26, c=5.

x=(−b±√b2−4ac)/2a

x=−(−26)±√(−26)2−4(16)(5)/2(16)

x=13/16 + 1/16√89 or x=13/16+ −1/16√89

x=1.40 or 0.22
