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

Which graph represents the function y = sine (one-half x) after a shift of 3 units down?

Answers

The graph shows the  function y=sin(1/2x) after a shift of 3 units down .

What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We have to find the graph which represents the function y = sine (1/2x) after a shift of 3 units down

The sine function starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to −1.

According to the question

y=sin(1/2x) after a shift of 3 units down

y+3=sinx/2

Now.

x         y

0        -3

π         -2

-π        -4

Graph will be plotted on these points

Hence, the graph shows the  function y=sin(1/2x) after a shift of 3 units down .

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
