Answer:
3
Step-by-step explanation:
Intersections on the x axis occur when y = 0. f(x) is another term for y, so set f(x) equal to zero and solve for the two possible x's.
0 = x^2 - 3x - 40
0 = (x-8)(x+5)
By solving for x, you get 8 and -5. 8 and -5 added together will equal 3.
60x24=1440 1440x365=525600 525600x2000=1,051,200,000 about 2000 years
Answer:
$307.5.
Step-by-step explanation:
We have been given that Elena's aunt bought her a $150 savings bond when she was born.When Elena is 20 years old, the bond will have earned 105% in interest.
To find bond's value after 20 years we will add 105% of 150 to 150.
Therefore, the bond will be worth $307.5, when Elena will be 20 years old.
They have different angle's degrees acute are degrees lesser than 90°, and right angle are 90° only, and obtuse angles are angle degrees more than 90° degrees
To find the answer,we can simply multiply 275 by 2-1/2:
275×2-1/2
=275×(2×2+1)/2
=275×5/2
=1375/2
=678-1/2
Therefore, the answer is 678-1/2.
Hope it helps!
