Answer:
Vertex → (2, 4)
Step-by-step explanation:
Quadratic equation has been given as,
y = -x² + 4x
We rewrite this equation in the form of a function as,
f(x) = - x² + 4x
By comparing this equation with the standard quadratic equation,
y = ax² + bx + c
a = -1 and b = 4
Vertex of the parabola represented by this equation is given by ![[-\frac{b}{2a}, f(\frac{-b}{2a})]](https://tex.z-dn.net/?f=%5B-%5Cfrac%7Bb%7D%7B2a%7D%2C%20f%28%5Cfrac%7B-b%7D%7B2a%7D%29%5D)
x coordinate = 
= 2
y-coordinate = f(2)
= - (2)² + 4(2)
= -4 + 8
= 4
Therefore, vertex of the given function is (2, 4)
Angle EGF = x
Sin x = 12/18.6
Sinx ≈ 0.6452
x ≈ Sin⁻¹(0.6452). Use a calculator.
x ≈ 40.18°
x ≈ 40.2°
Second option.
Answer:
49x+36
Step-by-step explanation:
Hey There!
for this question they would like you to simplify the expression using distributive property
To do this the first step is to distribute the 9 in to everything that is in the parenthesis
9x5x=45x
9x4=36
so now we have
45x+36+4x
the next step is to combine like terms
the only like terms in the expression are 45x and 4x so we just add the two together
45x+4x=49x
so now we have 49x+36
In conclusions the simplified version of that expression is 49x+36
