Question 5
What is a value of b will cause 27x^2+ bx +3 = 0 to have one real solution?

Answers

Answer:

The values of b are [tex]\mathbf{b=\pm18}[/tex]

Step-by-step explanation:

We need to find the value of b will cause [tex]27x^2+ bx +3 = 0[/tex] to have one real solution.

If it has one real solution, the discriminant is zero.

The formula of discriminant is: [tex]b^2-4ac[/tex]

In our case: [tex]b^2-4ac=0[/tex]

We have a=27, b=b and c=3

Putting values to find b

[tex]b^2-4ac=0\\b^2-4(27)(3)=0\\b^2-324=0\\b^2=324\\Taking \ square root \ on \ both \ sides\\\sqrt{b^2}=\sqrt{324}\\b=\pm18[/tex]

So, the values of b are [tex]\mathbf{b=\pm18}[/tex]

The vertex of this parabola is at (3,-2). When the x-value is 4, the y value is 3. What is the coefficient of the squared term in the parabola's equation?

Answers

Answer:

the coefficient of the squared expression is 5.

Step-by-step explanation:

the equation of a parabola in its vertex form is y=a(x-h)²+k, where (h, k) is the vertex of the parabola.

in this case, h=3, k=-2, so y=a(x-3)-2

plug (4,3) in the equation: 3=a(4-3)²-2, a=5

In the diagram, assume that y= 7. Find x and z.
A)
<= 7 V3; 2= 14
B)
x = 14; 2= 7 V3
©
x= 7 V2; 2 = 14
D)
x = 14; 2= 7V2

Answers

Answer:

A

Step-by-step explanation:

- to find x we use tan 60 = x/7

- rearrange, tan60*7 = x, x = [tex]7\sqrt{3}[/tex]

- now you have two sides so you can use pythagoras  to find z

y^2 + x^2 = z^2

z = [tex]\sqrt{(7\sqrt{3})^2 + (7)^2 }[/tex]

z = 14
