$the \: function \: is \:y = a {x}^{2} + c \\ then \: we \: put \: (0 \: \frac{1}{3} ) \: and \: ( - 3 \: \: \frac{82}{3} ) \: in \: the \: function \\ then \: we \: got \\ c = \frac{1}{3} \\ \frac{82}{ 3} =9a + c \\ then \: we \: can \: solve \: that \: \\ c = \frac{1}{3} \: \\ a = 3 \\ so \: the \: function \: is \: \\ y = 3 {x}^{2} + \frac{1}{3}$

hope this would help you .

Last one, use trigonometry to help you solve for y given that one side is 4 and there is an angle of 50 degrees.

Ostrovityanka [42]

Answer:

y = 6.22

You can solve this in two ways.

1.) Use SOH CAH TOA:

I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.

$\cos(angle) = \frac{adjacent}{hypotenuse}$

$\cos(50) = \frac{4}{y}$

$\cos(50) \times y = 4$

$y = \frac{4}{ \cos(50) }$

$y = 6.22$

2.) Use Law of Sines:

Solve for the last angle inside the triangle first.

$180 - (50 + 90) = 40$

Then use the angle you found (40°) in the equation.

$\frac{4}{ \sin(40) } = \frac{y}{ \sin(90) }$

$\frac{4}{ \sin(40) } \times \sin(90) = y$

$y = 6.22$

How do I get 1/2 divided by 1/4 step by step

finlep [7]

Such as 1/2 ÷ 1/4, we flip the second fraction and then we simply multiply the numerators with each other and the denominator with each other then we get the answer 2

Given: f(x) = x - 7 and h(x) = 2x +3

forsale [732]

Answer:

h(f(x)) = 2x - 11

Step-by-step explanation:

substitute for x in h (x), the values of f(x)

h(f(x))= 2(x-7)+3

=2x-14+3

=2x-11
