Answer:

• multiplied by 4p: (x -h)² +4pk = 0

• zeros for k > 0: none

• zeros for k = 0: one

• zeros for k < 0: two

Step-by-step explanation:

a) Multiplying by 4p removes the 1/(4p) factor from the squared term, but adds a factor of 4p to the k term. (It has no effect on the subsequent questions or answers, so we wonder why we're doing this.) The result is ...

(x -h)² +4pk = 0

__

b) The value of k is the vertical location of the vertex of the parabola with respect to the x-axis. The parabola opens upward, so for k > 0, the parabola does not cross the x-axis, and the number of real zeros is zero. (There are two complex zeros.)

__

c) As in part b, the value of k defines the vertex location. When it is zero, the vertex of the parabola is on the x-axis, so there is one real zero (It is considered to have multiplicity 2.)

__

d) As in part b, the value of k defines the vertex location. When it is negative, the vertex of the parabola is below the x-axis. Since the parabola opens upward, both branches will cross the x-axis, resulting in two real zeros.

_____

The attached graph shows a parabola with p=1/4 and h=2. The values shown for k are +1, 0, and -1. The coordinates of the real zeros are shown.

The area of a square is 64n^36 square units. what is the side length of one side of the square
sesenic [268]
Area = (side length)^2

Here,
 64n^36 = s^2.  Take the sqrt of both sides, obtaining 8n^18 = s.  This is the principal square root.  We use this positive quantity because the measure of side length must be positive.

Find the measures of the indicated angles pictures included!!!
vazorg [7]

Answer:

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

I’ll give you best answer and a thanks plsplspls help i’m legit freaking out i keep getting decimals

First, find R angle at TRS = 180-(10x+13)
then you know that total angles of a triangle is 180 so
TRS+RST+STR
180-(10x+13) + 8x+1 + 34 = 180
180-10x-13+8x+1+34 = 180
-13+1+34 = 10x-8x
22 = 2x
then x = 11
