ZA and ZB are vertical angles. If m_A = (4x – 13)° and m
ZB = (3x + 19)', then find the measure of ZA.
Answers
Answer:
115 degrees
Step-by-step explanation:
Vertical angles are congruent by the vertical angles theorem.
Hence,
<A=<B
4x-13=3x+19
x=32
Substituting 32 in for x in <A
4(32)-13= 115

What is the value of the expression? 8.5 - (-4.8) - 7
Answers
Answer:
6.3
Step-by-step explanation:
8.5 - (-4.8)
Let's focus on - (-4.8)
if a negative number is subtracted, it reverses itself
In other words, if a negative number is being subtracted, it is the same as being added as a positive number
So we change the equation to
8.5 + 4.8 = 13.3
Now we subtract 7 from 13.3
Since positive 7 is being subtracted, the rule for -4.8 does not apply to it
13.3 - 7 = 6.3

Answers
Answer:
15+3n
Step-by-step explanation:
Answer:
[tex]a_{n} =15+3n[/tex]
Step-by-step explanation:
In this sequence, each term increases by 3, which means it is arithmetic with a common difference of 3. The explicit formula for an arithmetic sequence is [tex]a_{n}=a_{0} +dn[/tex], where [tex]a_{0}[/tex] is the zeroth term and d is the common difference. To find the answer simply plug in the values. The zeroth term is 15, we get this by going back one term before the sequence started, so subtracting 3 from 18. Then plugin 3 for d and you get your final answer.

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?
Answers
Step-by-step explanation:
sin2x - sinx = 0
2sinxcosx - sinx = 0
(Double Angle Formula)
sinx(2cosx - 1) = 0
Either sinx = 0 or cosx = 1/2.
When sinx = 0,
x = 0 or x = π.
When cosx = 1/2,
x = π/3 or x = 5π/3.
Hence the solutions are
x = 0, x = π/3, x = π or x = 5π/3.

Please Help
Answers
Answer:
I believe the answer is 4. Please correct me if I’m wrong.
Step-by-step explanation:
================================================
Work Shown:
A = old velocity = 2 m/s
B = new velocity = 10 m/s
C = change in time = 5 seconds
D = average acceleration
D = (change in velocity)/(change in time)
D = (B-A)/C
D = (10-2)/5
D = 8/5
D = 1.6 m/s^2
The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.

Michael bought a guitar that was on sale for 15% off the regular price of $200. The total cost included 8% sales tax. What was the total cost?
Answers
Answer:
$183.60
Step-by-step explanation:
Take the regular price and find the 15% discount:
200 x 0.15 = 30
Subtract the discounted amount from the original price:
200 - 30 = 170
Take the new price and find the sales tax:
170 x 0.08 = 13.60
Add the sales tax to the discounted price:
170 + 13.60 = 183.60
