Answer:
3.1*10^10
Step-by-step explanation:
31 billion would be written like that because... there are 9 0's left, and that goes up to 10 because i turned 31 to 3.1 not 31, so that value after a decimal point adds 1
Answer:
-$3.25
Step-by-step explanation:
She had $5 to begin with and ended with $1.75 the change is - because she has less 5-1.75=3.25
Answer: At least two sides are congruent
Step-by-step explanation:
Here is the complete question:
If a triangle JKL is classified as isosceles, which statement is true?
a. At least two sides are congruent.
b. Two sides are perpendicular.
c. All three sides are congruent.
d. Two sides are parallel.
An isosceles triangle is a triangle that has at least two sides that are equal. An isosceles triangle has two equal sides and also two equal angles.
An angle is said to be congruent if it has the same angle either in degrees or radians. Such angles don't necessarily have to point in same direction. Therefore, it is true that at least two sides are congruent.
Answer:
24
Step-by-step explanation:
use Pythagoras theorem
a^2 + b^2 = c^2
18^2+b^2=30^2
b^2 = 30^2 - 18^2
b = √576 =24
Answer:
D
Step-by-step explanation:
Ordenered pairs g(x):
(0,0); (2,2); (- 2,2)
g(x) = ax² + bx + c
(0,0)
a.0² + b.0 + c = 0
c = 0
(2,2)
a.2² + b.2 + c = 2
4a + 2b = 2
(- 2,2)
a.(- 2)² + b.(- 2) + c = 2
4a - 2b = 2
4a + 2b = 4a - 2b
2b + 2b = 0
4b = 0
b = 0
4a + 2b = 2
4a = 2
a = 2/4
a = 1/2
g(x) = 1/2x² + 0x + 0
g(x) = 1/2x²
