Step-by-step explanation:
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
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

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?
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

What is 5x+24=134 thank you so mich have a wonderful day
Answer:
x = 22
Step-by-step explanation:
5x + 24 = 134
134 - 24 = 110
110 / 5 = 22
x = 22
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?
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.

True or False? The measure of a tangent-chord angle is twice the measure of
the intercepted arc inside the angle.
The statement made which says the tangent - chord angle is twice the measure of the intercepted arc inside the angle is FALSE.
According to the angle theorem, the angle formed by the intersection of the chord and tangent on a circle is twice the measure of the intercepted arc. This means that the intercepted arc is twice the measure of the angle formed and not the other way round.Therefore, the statement is False because the intercepted arc is twice the measure of the angle formed by the intersection of the chord and the tangent on the circle.

Can someone help me with my homework, please?
Answer:
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

x = 20
Tia rounds a number, x , to 3 sf. The result is 9.73. Write the error interval for x in the form a ≤ x < b .
Answer: 9.725 ≤ x ≤ 9.734
Step-by-step explanation:
We know that 9.73 is rounded, then we need to look at the next digit after the last one of 9.73, this would be the third digit after the decimal point.
We know that if this digit is smaller than 5, then we round down.
Then the largest number that can be rounded down to 9.73 is:
9.734
Now we want to find the smallest number that can be rounded up to 9.73
We know that if the next digit is 5 or bigger, then we round up.
Then the number 9.725 is rounded up to 9.73
And this is the smallest number that can be rounded up to 9.73
Then the error interval is:
9.725 ≤ x ≤ 9.734

What is the vertex of f(x)=(x+3)2+4?
Answer:
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
Comparing this to the standard form we see that:
vertex = (-3, 4)

hey can you state what's wrong in the given solution.

[tex]0 = 0[/tex]
we know, zero is always equal to zero
=》
[tex]16 - 16 = 20 - 20[/tex]
because, 16 - 16 = 0
and 20 - 20 = 0
=》
taking 4 as common from 16 - 16 and 5 as common from 20 - 20
[tex]4(4 - 4) = 5(4 - 4)[/tex]
now dividing both sides by
(4 - 4)
=》
[tex] \frac{4(4 - 4)}{(4 - 4)} = \frac{5(4 - 4)}{(4 - 4)} [/tex]
=》
[tex]4 = 5[/tex]
because, (4 - 4) in denominators of both sides cancels out (4 - 4) in numerator of both sides.
=》
[tex]2 + 2 = 5[/tex]
we know, 4 = 2 + 2 , so plugging (2 + 2) in place of 4
