1÷2(2x+6)=4x-1
solve pls no links!!!
Answers
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0

A pendulum's first swing has an arc of 36 inches. As the pendulum swings back and forth, the arc length for each successive swing is 95% of the previous swing. If this pattern continues, at which swing of the pendulum will the length of the arc be less than 27 inches? A. 5th B. 6th C. 7th D. 9th
Answers
Answer:
7th
Step-by-step explanation:
Given :
Arc length on first swing = 36 inches
After successive swing, arc length decreases by 95%
Length on 2nd swing = 0.95 * 36 = 34.2
Length on 3rd swing = 0.95 * 34.2 = 32. 49
Length on 4th swing = 0.95 * 32.49 = 30.8085
Length on 5th swing = 0.95 * 30.8085 = 29.268075
Length on 6th swing = 0.95 * 29.268075 = 27.80467125
Length on 7th swing = 0.95 * 27.80467125 = 26.4144376875
26.4144376875 < 27
Hence, length falls below 27 on 7th swing

6 is 45° 1 is 45° x=10 hope this helps
Answer:
1) 45. Since it is congruent/corresponding to angle 7, which is 45 degrees.
2) 135. Because a straight line is 180 degrees, I substracted 45 from 180, getting 135 degrees, the measure of angle 1.
3) x = 20. Look at the work below.
Step-by-step explanation:
180 - 45 = 135
____________________________________________________________
5x + 35 = 135
-35 -35
5x = 100
divide by 5
x = 20
Lily and Wilder live 810 miles apart. If they leave at the same time and drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph, after how many hours will they meet?
Answers
Given:
Distance between Lily and Wilder = 810 miles
They drive towards each other with Lily driving at 55 mph and Wilder driving at 80 mph.
To find:
After how many hours will they meet?
Solution:
Lily driving at 55 mph and Wilder driving at 80 mph towards each other. So, the relative speed is:
Relative speed [tex]=(55+80)\text{ mph}[/tex]
[tex]=135 \text{ mph}[/tex]
We know that,
[tex]Time=\dfrac{Distance}{Speed}[/tex]
[tex]Time=\dfrac{810}{135}[/tex]
[tex]Time=6[/tex]
Therefore, Lily and Wilder will meet after 6 hours.

The daily advertising revenue (in dollars) for a local newspaper is given by the function R(t) = -18t2 + 720t – 103, where t is number of years that the paper has been in production. What is the daily advertising revenue after the paper has been in business for 15 years?
Answers
Answer:
6647
Step-by-step explanation:
The computation of the advertising revenue for 15 years is shown below:
Given that
r(t) = -18t^2 + 720t - 103
where
t = number of years = 15
now put the value of t in the above equation
= -18(15)^2 + 720(15) - 103
= -4050 + 10,800 - 103
= 6647

Below.
Step-by-step explanation:
f(x) = a(x - j)^2 + k is the standard vertex form where (j, k) is the vertex,
f(x) = (x + 3)^2 + 4

Answers
Answer:
9/10
Step-by-step explanation:
To solve this you need a common denominator, here we'll make it 10, leaving 7/10 and simplifying 20/100 by dividing both the 20 and 100 by 10 to get our common denominator of 10. Now we have 7/10 + 2/10 which is 9/10.
