OAB is a triangle
OA = 4a and OB = 5b
M is the midpoint of OB
AN:NB = 2:3
Find OP:PN
Answer:
5:2
Step-by-step explanation:
ON = OA + AN
AN = 2/5AB
AB = 5b-4a
AN = 2b - 8/5a
ON = 4a - 8/5a +2b
ON = 12/5a+2b
OP = k(12/5a+2b)
OP = OA + AP
AP = x(AM)
AM = 5/2b-4a
OP=4a-4ax+5/2bx
OP=4a-4ax+5/2bx and OP=12/5ak+2bk
Coefficients of A
4-4x=12/5k
k=(20-20x)/12
Coefficients of B
5/2x=2k
k=5/4x
(20-20x)/12 =5/4x
20=35x
x=4/7
k=5/4 * 4/7 = 5/7
OP=k(ON)
OP = 5/7
PN = 2/7
OP:PN = 5:2

Give the equation the circle (X+5)^2+(y-1)^2=16, which correctly gives the center and radius of the circle
Answer:
Step-by-step explanation:
You have:
[tex](x+5)^2+(y-1)^2=16[/tex]
[tex](x+5)^2+(y-1)^2=4^2[/tex]
To find the center of the circle, you want to find the 'x' and 'y' values which make their respective term equal zero:
[tex](x+5)^2=0[/tex]
[tex](y-1)^2=0[/tex]
[tex]x=-5[/tex]
[tex]y=1[/tex]
The radius of the circle would be 4 due to the right side of the circle equation. Our circle is centered at (-5, 1) and has a radius of 4 units.

Answer:
60,60,60
Step-by-step explanation:
The angle measures for the triangle is 60, 60 and 60.
What is Triangle?A triangle is a polygon with three vertices and three sides. The angles of the triangle are formed by the connection of the three sides end to end at a point. The triangle's three angles add up to 180 degrees in total.
We have,
The measure of three sides are 6 ,6 and 6.
Now, we know a triangle whose three sides are equal is called as Equilateral Triangle.
Also, three angles are Equal.
Using Angle Sum property
x + x + x = 180
3x= 180
x= 60
Thus, the measure of three angles are 60, 60 and 60.

If a student wants to multiply by 8 they can?
A. Multiply by 2 three times
B Multiply by 2 four times
C Multiply by 4 twice
D Multiply 2 and multiply by 4 and add them together
Hello Brainly user,
A. Multiply by 2 three times if you want to multiply by 8.
Proof:
For example, if you want to multiply 2 by 8 --> 2x8 then you can just do 2x2 = 4 4x2 = 8 8x2 = 16.
TO CHECK:
You can do 8x2 = 16.
Hence, this answer is 100% correct.

Answer:
[tex]x=0, \dfrac{\pi}{6},\dfrac{5\pi}{6},\pi \:\sf(for\:the\:given\:interval)[/tex]
Step-by-step explanation:
given interval [0, 2π) = 0 ≤ x < 2π
[tex]2\sin^2(x)=\sin(x)[/tex]
subtract sin(x) from both sides:
[tex]\implies 2\sin^2(x)-\sin(x)=0[/tex]
factor:
[tex]\implies \sin(x)[2\sin(x)-1]=0[/tex]
[tex]\sin(x)=0[/tex]
[tex]\implies x=0 \pm2 \pi n, \pi \pm2 \pi n[/tex]
[tex]\implies x=0, \pi \:\sf(for\:the\:given\:interval)[/tex]

square units. What is the height of the rectangle in terms of x?
A (4 - x) units
(x-2) units
B (4x3 - 2x2) units
D (4x - 2) units
-
-
The area of the rectangle is the product of its base and height
The height of the rectangle is 4x - 2 units
How to determine the height?The given parameters are:
Area = 4x^2 - 2x
Base = x
The area of the rectangle is:
Area = Base * Height
This gives
4x^2 - 2x = x * Height
Divide through by x
4x - 2 = Height
Rewrite as:
Height = 4x - 2
Hence, the height of the rectangle is 4x - 2 units
