I’m kinda confused. Can someone help.
horsena [70]

Answer:

PQ = PM\cos MPQ + MQ\cos MQP=2PM\cos MQP

Step-by-step explanation:

given MQR = 60, PQR = 75

MQP = 75 -60= 15QR = ((18(1+\cos 30))^{2}-(2\cos 15)^{2})^{\frac{1}{2}}

WE KNOW THAT MQR +QRM +QMR = 180

MPQ = MQP AS ANGLE OPPOSITE TO EQUAL SIDES ARE EQUAL

THEREFORE QMR = 90 - 60 = 30

therefore PQM = 75 - 60 = 15

PM = PQ because M is the mid point

therefore PR = PM + MQ\cos QMR

                PR = 18(1+\cos 30)

QR = (PR^{2}-PQ^{2}))^{\frac{1}{2}}

PQ = PM\cos MPQ + MQ\cos MQP=2PM\cos MQP

Pls help I’ll make brainlest and give extra points
allochka39001 [22]

Answer:

p>-3 open circle going to the right

m\leq -4 closed circle going to the left

n<5 open circle going to the left

h\geq 2 closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Step-by-step explanation:

Before I answer these here are some good notes

If the inequality sign is < or > then the circle is going to be open

If the inequality sign is \leq  or\geq then the circle is going to be closed

If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right

If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left

p>-3 open circle going to the right

m\leq -4 closed circle going to the left

n<5 open circle going to the left

h\geq 2 closed circle going to the right

1>x open circle going to the left

-1=d just a closed circle

Firlakuza [10]

Answer:

5/10=u/9

explain answer: so to get this answer 5x8=40 so like the closes number to eight will be 9 and 10 but they said closes 10 so it will be 5/10 and =u/9 so answer= 5/10=u/9

D. x^4+-4x^2+-7x^2+28

           x^4-11x^2+28

====================================

Step-by-step explanation:

A. (3x*2x)+(3x*-5)+(7*2x)+(7*-5)

        Multiply and simplify.

                6x^2+9x-35

B. (x^2*5x^2)+(x^2*-3x)+(2x*5x^2)+(2x*-3x)

         Multiply and simplify.

              5x^4+7x^3-6x^2

C. (5x*5x)+(5x*-4)+(4*5x)+(4*-4)

         Multiply and simplify.

                  25x^2-16

D. (x^2*x^2)+(x^2*-4)+(-7*x^2)+(-7*-4)

         Multiply and simplify.

                x^4-11x^2+28

I hope this helps!

But you should really do this yourself.
