Answer:
answer is {-4.42, 12.54}
Step-by-step explanation:
v^2 - 8v - 59 = -2
v^2 - 8v = 57
(v - 4)^2 - 16 = 57
(v - 4)^2 = 73
Taking square roots:-
v - 4 = +/- √73
v = √73 + 4 or - √73 + 4
v = -4.54 , 12.54
Answer:
I think its B.) Yes, because the ratios simplify to the same number., sorry if it's wrong
Step-by-step explanation:
50/10 = 1/5
60/12 = 1/5
70/14 = 1/5
80/16 = 1/5
They all simplify to the same proportion.
Answer:
The remaining interior angles of this triangle are 140º and 10º
Step-by-step explanation:
The sum of the interior angles of a triangle is always 180º.
A triangle has 3 angles. In this problem, we have one of them, that i am going to call A1 = 30º.
The sum of a interior angle with it's respective exterior angle is also always 180º.
We have that one of the exterior angles is equal to 40°. So it's respective interior angle is
40º + A2 = 180º
A2 = 180º - 40º
A2 = 140º
Now we have two interior angles, and we know that the sum of the 3 interior angles is 180º. So:
A1 + A2 + A3 = 180º
A3 = 180º - A1 - A2
A3 = 180º - 30º - 140º
A3 = 180º - 170º
A3 = 10º
Answer:
(0,5)
Step-by-step explanation:
Y intercept is where line touches y axis so x = 0.
(0,5) since it's only 5 and the others don't count.
Answer:
8 tables
Step-by-step explanation:
since she makes on average $18 per table and wants to make $180 we can just multiply $18 by 10 tables however we have to take into account the $36 she makes per night. 36 is just 18 multiplied by 2 meaning we can subtract a total of 2 tables away from the total of 10 tables to get 8 tables
