Answer: 0,5, and -4 is the zeros
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
- Loss=C.P-S.P
- Loss=10000-8000
- Loss=2000
- Loss%=loss/cp*100
- Loss%=2000/10000*100
- Loss%=20%
Answer:
#1 is 30 degrees
#2 is obtuse
#3 is "No rhombuses are rectangles"
#4 is D
#5 is A
Step-by-step explanation:
For #1, we have an angle vertical to 120 degrees which includes a right angle, so we make an equation:
90+x=120
x=30
So angle x is 30 degrees aka. Option A
For #2, obtuse angles have the sum of the square of the side lengths that are less than the square of the hypotenuse. In this case, 6^2+4^2<9^2 or 50<81
For #3, rhombuses have two pairs of congruent sides but no right angles while rectangles have two pairs of congruent sides but they also have right angles.
For #4, they are similar because one of the triangles is dialated by a scale factor of 1.5.
For #5, just think of turning the triangle on its other side, aka. option A
Answer:
Step-by-step explanation:
For #2, remember that , so Also, (a+b)(a-b), where a and b are any numbers, (a+b)(a-b)=. Now, to simplify, or radicalize, a number with surds in the denominator, you have to multiply the denominator by its conjugate. If there is a complex number , where a and b are any numbers, the conjugate is always . Lets apply these rules. The conjugate of 4+6i is 4-6i, so do this:
Our answer is (28-3i)/(26)!
Answer:
b
