The area of the triangle is 270 centimeters. The way that I found that out is the equation 30x18/2
Answer:
It's a mnemonic device to help you remember the three basic trig ratios used to solve for missing sides and angles in a right triangle.
Step-by-step explanation:
A quadratic equation is an equation whose leading coefficient is of second degree. The time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.
<h3>What is a quadratic equation?</h3>
A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
The jump is represented by the equation h(x)= -16x²+4x+6. The time is represented by x, now the height of the athlete will be zero when the jump will be completed therefore, we can write,
0 = - 16x² + 4x + 6
0 = - 16x² + 12x - 8x + 6
0 = -4x(4x-3) -2(4x-3)
0 = (-4x-2)(4x-3)
x = -0.50, 0.75
Since the time can not be negative, therefore, the time in which the athlete complete the jump is 0.75 seconds.

Answer:
<u>X=7,-3</u>
Step-by-step explanation:
x^(2)-4x-21=0
(x-7)(x+3)=0
x=7,x=-3
Answer:
y = - x + 3
Step-by-step explanation:
Parallel lines have equal slopes
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate the slope m of AB using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(0, - 2) and (x₂, y₂ ) = B(- 4, 2)
m= = = - 1
Thus the slope of the line going through C is m = - 1
Note C(0, 3 ) ⇒ c = 3
y = - x + 3 ← equation of line through C
