What is the value for m and n?
Inga [223]

Answer:

M = 8 N = 10

Step-by-step explanation:

Multiplying exponents adds the exponent, meaning that inside of the brackets, it is a^4 * b^5. Multiply the exponents by two because you are squaring the entire equation. Therefore, m=8 and n=10

Yakvenalex [24]

Answer:

3rd quadrant

Step-by-step explanation:

  • First we just convert the angle from radians to degrees
  • \frac{31\pi radians }{6}*\frac{180degrees}{\pi radians}  =\frac{31*180}{6} degrees=930degrees
  • Now that's too big, all this means is if we start rotating from the positive y-axis in a circle we will cross the starting point 2 times, 2 full circles;
  • 930degrees-360degrees=570degrees\\570degrees-360degrees=210degrees  
  • Now in which quadrant it 210 degrees?
  • 0 degrees to 90 degrees is 1st quadrant
  • 90 degrees to 180 degrees is 2nd quadrant
  • 180 degrees to 270 degrees is 3rd quadrant
  • 270 degrees to 360 degrees is 4th quadrant
  • So our answer is the 3rd quadrant.

One angle in an obtuse isosceles triangle measures 40°. What are the measures of the other two angles?
Damm [24]
An obtuse triangle has one obtuse angle, or an angle that measures more than 90° but less than 180°. Options 1 and 2 are not correct, because these are acute angles.
So, one of the angles must be 40°, and the other may be 100° or 120°.
The measures of the angles in a triangle add up to 180°.
40^\circ + 40^\circ +x = 180^\circ \\&#10;80^\circ + x=180^\circ \\&#10;x=180^\circ - 80^\circ \\&#10;x=100^\circ
The other two angles are 40° and 100°.

4 (4b + 3) + 2b = 3 (6 - 11)
erma4kov [3.2K]
Solve for b?
1. Distribute “4(4b+3)” and “3(6-11)”
16b+12+2b=18-33

2. combine like terms
18b+12=-15
18b=-27
b=-27/18

3. simplify
b=3/2
