Let a and b be irrational numbers. Is (ab)^2 always rational, sometimes rational, or never rational?

1 answer:

7 0

When you multiply 2 irrational numbers, the result is always irrational. This applies to squaring as well since it is still multiplying irrational numbers together (though the terms are the same)

Final answer: never rational

Which is the graph of y = 2.5x? A. B. C. D.

Thepotemich [5.8K]

The answer is D. because first you got solve the problem.

y=2.5x
(turn y to 0)
0= 2.5x
÷2.5 ÷2.5
_________
0=x

So we got one answer (0,0)

y=2.5x
(turn x to 0)
y= 2.5(0)
y=2.5

(2.5, 0)

When you do (0,0) (2.5,0) on the graph it will look like D.)

One angle of an isosceles triangle measures 110°. Which other angles could be in that isosceles triangle? Choose all that apply.

andre [41]

Answer:

Therefore the correct option is 2. 35 degree.

$\angle ABC=\angle ACB=35\°$

Step-by-step explanation:

Consider an Isosceles Triangle, Δ ABC where,

∠BAC = 110°

TO Find:

∠ ABC = ∠ACB = ?

Solution:

For an Isosceles Triangle

Base Angles are equal

∴ $\angle ABC=\angle ACB=x\ (say)$

Now,

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\110+x+x=180\\\therefore 2x=180-110=70\\\therefore x=\dfrac{70}{2}=35\°$

Therefore,

$\angle ABC=\angle ACB=35\°$
