Write the equation of the following graph in vertex form.
Marat540 [252]

Answer:

Correct choice is 2. f(x)=0.4(x+2)(x-5)

Step-by-step explanation:

We have been given a graph of the quadratic function. Now we need to use that graph to find the equation of the graph in vertex form. By the way given choices written in intercept form so to be accurate we are going to find the equation in intercept form.

from graph we see that x-intercepts are at 5 and -2.

we know that if x=a is x-intercept then (x-a) must be factor.

So (x+2)(x-5) is the factor.

when leading coefficient is positive then graph opens upward.

so that means leading coefficient is 0.4

Hence correct choice is 2. f(x)=0.4(x+2)(x-5)

8x-11+5x+2x+6=180 what is the measurement for x.
Verizon [17]

I assume you're looking for the value of x?

Combine like terms: 8x+5x+2x-11+6=180 -> 15x-5=180

Add 5 to both sides: 15x=185

Divide both sides by 15: x=12 1/3

So x is 12 1/3 or 37/3

Hope this helped!

Help!!!!!!!!!!!!!!!!!!!!!!!!!
torisob [31]

Answer:

53

Step-by-step explanation:

\frac{sin(56)}{78.6}  =  \frac{sin(90)}{ab}  \\  \\ absin(56) = sin(90) \times 78.6 \\  \\ ab =  \frac{sin(90) \times 78.6}{sin(56)}  \\ ab = 94.8 \\  \\  {x}^{2}   +  {78.6}^{2}  =  {94.8}^{2}  \\  {x}^{2}  =  {94.8}^{2}  -  {78.6}^{2}  \\  {x}^{2}  = 8987.04 - 6177.96 \\  {x}^{2}  = 2809.08 \\ x =  \sqrt{2809.08}  \\ x = 53
