Select the ONLY incorrect way the angle can be named
PIT_PIT [208]

Answer:

The only incorrect way could be to call it PN

Step-by-step explanation:

NOP shows the angle from NOP from two lines

O shows that is declaring angle O

PON is just the reverse of NOP.

However, on the other hand, PN is incorrect because first of all, that's how someone notate lines, and second of all, PN does not exist.

What is the equation, in slope-intercept form, of the line that contains the points (3, -4) and (5 -6)
Alika [10]

Answer:

y = -x - 7

Step-by-step explanation:

As we move from the point (3, -4) to the point (5, -6), x increases by 2 and y decreases by 2.  Thus, the slope of this line is m = rise / run = -2/2, or -1.

Starting with the general slope-intercept form of the equation of a straight line, we get y = mx + b => y = -1x + b.

Subbing -4 for y and 3 for x, we get

-4 = -1(3) + b, which yields b = -1

Thus, the desired equation is

y = -x - 1

Find AC please, help is very much appreciated.
fenix001 [56]

Answer:

AC ≈ 67.9

Step-by-step explanation:

15² = 9 (3x + 1 + 9)

225 = 9 (3x + 10)

225 = 27x + 90

135 = 27x

x ≈ 19.29

AC = (3x + 1 + 9)

AC = 3 (19.2857...) + 1 + 9

AC = 57.857... + 1 + 9

AC =  57.857... + 10

AC ≈ 67.9

Point E is the midpoint of AB and point F is the midpoint
GREYUIT [131]

The options are;

1) AB is bisected by CD

2) CD is bisected by AB

3) AE = 1/2 AB

4) EF = 1/2 ED

5) FD= EB

6) CE + EF = FD

Answer:

Options 1, 3 & 6 are correct

Step-by-step explanation:

We are told that Point E is the midpoint of AB. Thus, any line that passes through point E will bisect AB into two equal parts.

The only line passing through point E is line CD.

Thus, we can say that line AB is bisected by pine CD. - - - (1)

Also, since E is midpoint of Line AB, it means that;

AE = EB

Thus, AE = EB = ½AB - - - (2)

Also, we are told that F is the mid-point of CD.

Thus;

CF = FD

Point E lies between C and F.

Thus;

CE + EF = CF

Since CF =FD

Thus;

CE + EF = FD - - - (3)

What is the volume of a cone with a radius of 2 and a height of 19?
kykrilka [37]

Remember that the cone volume formula is V=\pi r^2\frac{h}{3} , with r = radius and h = height. Using our information, we can form our equation as such: V=\pi 2^2\frac{19}{3} (I'll be keeping the answer in pi form.)

Firstly, solve the exponents:V=\pi 4\frac{19}{3}

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3
