Vertex form uses the following formula:

y = a(x-h)^2 + k

Identify the values of h and k in your function:

(x+5)^2 - 28
h = -5, k = -28

The vertex is found with the following point:

(h,k)
\text{Vertex: (-5, -28)}

The vertex will be found at (-5, -28).

denis-greek [22]

Answer:

180

Step-by-step explanation:

If 35% did not wear happy faces, then 100% -35% = 65% did wear happy faces.

Then we have ...

... 117 = 65% × (all children)

... 117/0.65 = all children = 180 . . . . . . divide by 65% = 65/100 = 0.65

There were 180 children in all.

m_a_m_a [10]

The measure of the angle m∠CBD that forms an adjacent angle is 35 degrees.

<h3>What are adjacent angles?</h3>

Adjacent angles are angles that have common side and vertex.

Therefore, the common vertex is at point B.

m∠CBD = m∠ABD -  m∠ABC

Therefore,

m∠ABD = 75 degrees

m∠ABC = 40 degrees

Hence,

m∠CBD = 75 - 40

m∠CBD = 35 degrees

a 10-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground 9 feet
kompoz [17]
If this is a problem about the Pythagorean theorem, maybe this helps! If the length of the ladder is 10 feet (C) and the base is 9 feet (B), you have to multiply each number by 2, add the total of both numbers and then round the number to the nearest hundreths ( use the radical button on your calculator) and there you have it , you will have the answer on your calculator. I hope this helps ;-)

Write the equation for this line in slope intercept form
elena-s [515]

Answer:

y = \frac{3}{2}x + 2

Step-by-step explanation:

Slope-intercept form is y = mx + b with m as the slope and b as the y-intercept.

The y-intercept is the point where the line intersects the y- axis.

y = mx + 2

The equation to find slope is \frac{y1-y2}{x1-x2}       Two points from the line: (0,2) (4,8)

\frac{8-2}{4-0} = \frac{6}{4} = \frac{3}{2}

y = \frac{3}{2}x + 2
