Answer:
a₁ = - 256 , r = -
Step-by-step explanation:
The nth term of a geometric sequence is
= a₁
Given
= - 256 , then by comparison
a₁ = - 256 and r = -
Answer:
The solution is:
Step-by-step explanation:
We have the following equations
To solve the system multiply by 3 the second equation and add it to the first equation
---------------------------------------
Now substitute the value of x in any of the two equations and solve for y
The solution is:
Answer:
17/7, y = 21 * (17/7), 51
Step-by-step explanation:
so to find what x is, we need to find how much it rises in 1 minute. we do that by dividing 17 by 7. we then see that we want to find how much is it filled in 21 minutes. we then multiply (17/7) by 21 to find the y which is 51
Answer:
21, 35 , 49
Step-by-step explanation:
21 = 3 * 7
35 = 5 * 7
49 = 7 * 7
GCF = 7
Given:
A figure of a right triangle with perpendicular 500 m and hypotenuse x.
To find:
The value of x.
Solution:
If a transversal line intersect two parallel lines, then alternate interior angles are congruent.
Using the above definition the measure of angle opposite to the perpendicular is 40 degrees.
In a right angle triangle,
In the given triangle,
Round the value to the nearest tenth.
Therefore, the value of x is 777.9 m.
