Answer:

8

Step-by-step explanation:

so QM and OM are equal to each other. the difference between these is that one is 5 and the other is 10. put these over each other to see how different they are. 1/2 is what the relationship so you want the same relationship with the other triangle. 4/8 equals 1/2 so it would be 8!

Help meeee!!!!!!!!!!!!!!!!!!!
Ivenika [448]

Answer:

Y=-2x

When x= -6 then y =12

Step-by-step explanation:

If y and x in direct variation then y=c*x for some constant c.

We are told

-4=c2

——> c= -2

So y= -2x

When x= -6 this becomes

Y= (-2) * (-6)

——> y = 12

Instructions: Find the measure of the indicated angle to the<br> nearest degree
Artemon [7]

Answer:

? = 57

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos ? = adj/ hyp

cos ? = 14/26

Taking the inverse cos of each side

cos ^-1 ( cos ?) = cos ^-1 ( 14/26)

? = 57.42102961

To the nearest degree

? = 57

The problem is in the picture :)
frozen [14]

Answer:

Last option: 4

Step-by-step explanation:

The quadratic equation simplified: x^2-4x=-\frac{7}{2} has the form:

ax^2+bx=c

In this case, you can identify that "a", "b" and "c" are:

a=1\\b=-4\\c=-\frac{7}{2}

To solve this quadratic equation  by completing the square, Carlos should add (\frac{b}{2})^2 to both sides of the equation. This is:

(\frac{-4}{2})^2=(-2)^2=4

Then:

x^2-4x+4=-\frac{7}{2}+4

Therefore you can observe that the number he should add to both sides of the equation is: 4

sin 42 = x /21

21 sin 42 = x

14.05174273 =x

Rounding to the nearest tenth
