Prove This :
sin(A+B)+sin(A−B)=2sinA⋅cosB
Answer:
We know
sin (A + B) = sin A cos B + cos A sin B
sin (A - B) = sin A cos B - cos A sin B
(A + B) + sin (A - B)
= sin A cos B + cos A sin B + sin A cos B - cos A sin B
= sin A cos B + sin A cos B
= 2 sin A cos B

Answer:
z = -44
Step-by-step explanation:
3/4 (x - 8) = 4
3(x - 8) = 16
3x - 24 = 16
3x = 40
x = 40/3
4 - 2x = -5x - z
4 = -3x - z
z = -3x - 4
z = -3(40/3) - 4
z = -40 - 4
z = -44
Answer:
Z=-44
Step-by-step explanation:
To figure out z. we have to figure out x first
So
3/4(x-8)=4
x-8=4÷3/4
x-8=4×4/3
x-8=16/3
3x-24=16
3x=16+24
3x=40
x=40/3
Now
4-2(40/3)=-5(40/3)-z
4-80/3=-200/3-z
z-68/3=-200/3
z=-200/3+68/3
z=-44

Answer it guys pls idk how... you can also show the steps. For those who answer it all correctly I will give the brainliest answer
Answer:
essentially, in these problems, youre finding the square root of each number. the square root should be a decimal thats in between two other numbers, and those will be the integers that the value of the square root is between. unless the value is exactly a number and a half, it will be closer to one integer than the other. the work is below.
square root of:
59= 7.68
68= 8.246
78= 8.83
93= 9.64
104= 10.198
124= 11.14
33= 5.74
185= 13.6
215= 14.66
these are just the square roots. but, as you can see, each number is between two other whole numbers on a number line. So, just write down what those numbers are.
7.68 is between 7 and 8
8.246 is between 8 and 9
8.83 is between 8 and 9
9.64 is between 9 and 10
10.198 is between 10 and 11
11.14 is between 11 and 12
5.74 is between 5 and 6
13.6 is between 13 and 14
14.66 is between 14 and 15
so, we know thw numbers that each decimal is between, but we have to find which one each is cloest to. in order to do that, just know that if the decimal is more than .5 its closer to the larger number, and its its less than .5, its closer to thw smaller number.
7.68 is closer to 8
8.246 is closer to 8
8.83 is closer to 9
9.64 is closer to 10
10.198 is closer to 10
11.14 is closer to 11
5.74 is closer to 6
13.6 is closer to 14
14.66 is closer to 15

Abba grew 1 foot over the past year . He is now 5 feet tall. Draw a bar model to compare abba's previous height to the amount he grew over the past year
Answer:
Please find attached the bar model that shows the comparison between Abba's previous height to the height by which Abba grew over the past year
Step-by-step explanation:
A bar model, in mathematics, is defined as a graphic depiction of a given quantity represented by numbers presented in a rectangular box or bar form that is then applied in finding numerical relationship solutions
The height by which Abba grew over the past 1 year = 1 ft.
Abba's current height = 5 feet
Therefore, Abba's initial height = 5 feet - 1 foot = 4 feet
Please find attached the bar model that compares Abba's previous height to the height Abba grew over the past year created with Microsoft Visio
If Tony earns five dollars on Monday and five dollars on Tuesday is that a sum of zero? need help I’m in 4th
Answer:
The sum is $10
Step-by-step explanation:
Since Tony got $5 on Monday and $5 on Tuesday, we can add them together by doing 5+5. We can add 5 and 5 together to get a total of $10 that Tony has earned. This means that it isn't a sum of 0 but a sum of 10.

9. Jeremy receives a base salary of $25,000 plus 5% commission on his sales. Jeremy received a total salary of
$45,000 last year. How much were his total sales?
a. $20,000
b. $70,000
c. $400,000
d $900,000
Answer:
c. $400,000
Step-by-step explanation:
Let his total sales be $x.
Salary + commission =$45000
[tex] \therefore \: 25000 + 5 \% \: of \: x = 45000 \\ \\ \frac{5}{100} x = 45000 - 25000 \\ \\ \frac{1}{20}x = 20000 \\ \\ x = 20 \times 20000 \\ \\ x = \$\:400, 000[/tex]
8. What is the annual salary for someone who earns a biweekly salary
of $863.00?
Answer:
approximately $22438
Explanation:
If this is wrong which im pretty sure it isnt, im sorry :)
Answer: Annual Salary = $22,438
===================================================
Work Shown:
biweekly means every 2 weeks
There are roughly 52 weeks in a year, so there are 52/2 = 26 biweekly paychecks over the course of the full year.
So the annual salary is 26*863.00 = 22,438 dollars.
How does the sketch of a graph of function help describe its behavior
Answer:
The end behavior of a function f describes the behavior of the graph of the function at the "ends" of the x-axis. In other words, the end behavior of a function describes the trend of the graph if we look to the right end of the x-axis (as x approaches +∞ ) and to the left end of the x-axis (as x approaches −∞ ).

3x-2y= 12
Linear Functions, please help, it’s on a test, and I’m about to fail this whole grade, thank you
Answer:
Slope: 3/2
y intercept (0,-6)
Step-by-step explanation:
3x-2y=12
First, solve for y
2y=12-3x
divide each term by -2 and simplify
y=-6+[tex]\frac{3x}{2}[/tex] or y=[tex]\frac{3}{2}[/tex]x-6
Slope intercept form: y=mx+b
therefor m =[tex]\frac{3}{2}[/tex] and y (0,-6)
b= 3x + 4g for a = -9 and b = 12
Answer:
B3x+2=32 and 5 with a but b=32c
Step-by-step explanation:
find the value of x and y
x° + 2y° = 180° ⇒ 2y° = 180° - x°
x° = 60° {three sides of the same lengh, means three angles=60°}
2y° = 180° - 60°
2y° = 120°
y° = 60°

Drake is considering buying one of the four popular e-readers where the e-reader's premium services is a monthly charge. The functions LaTeX: A_1\left(t\right)=\:5t+350,\:\:\:A_2\left(t\right)=10t+250,\:\:\:\:\:A_3\left(t\right)=499,\:and\:\:\:\:\:\:A_4\left(t\right)=15t+179A 1 ( t ) = 5 t + 350 , A 2 ( t ) = 10 t + 250 , A 3 ( t ) = 499 , a n d A 4 ( t ) = 15 t + 179 model the total amount of money A, in dollars, that Drake spends after buying the e-reader and subscribing to t months of the e-reader's premium services. Which e-reader has the greatest monthly subscription cost?
Answer:
[tex]A_4[/tex]
Step-by-step explanation:
The cost of the e-readers and the subscription of their services are
[tex]A_1(t)=5t+350[/tex]
[tex]A_2(t)=10t+250[/tex]
[tex]A_3(t)=499[/tex]
[tex]A_4(t)=15t+179[/tex]
The functions are of the form
[tex]A(t)=mt+c[/tex]
Where [tex]m[/tex] is the monthly subscription cost and [tex]c[/tex] is the cost of the e-reader.
So, 15 dollars is the highest subscription cost which is of the 4th e-reader.
Hence [tex]A_4[/tex] has the highest subscription cost.

Step-by-step explanation:
The attachment completes the question.
From the question, we understand that there are 4 individuals involved.
Mr. Preston (1)Mrs. Preston (1)The children (2)And they will spend one night
First, we need to calculate the expenses in Traveler's hotel.
[tex]Rate = \$107.10[/tex] (for 3 people)
[tex]Additional\ Person = \$21.55[/tex] (for 1 person)
[tex]Breakfast = \$8.75 * 4[/tex] (for 4 people)
[tex]Tax = \$16.85[/tex]
Total Expenses
[tex]Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85[/tex]
[tex]Total = \$107.10 + \$21.55 + \$35.00 + \$16.85[/tex]
[tex]Total = \$108.50[/tex]
For Sunny Side hotel:
[tex]Rate = \$152.95[/tex] (for 4 people)
[tex]Tax = \$21.34[/tex]
Total Expenses:
[tex]Total = \$152.95 + \$21.34[/tex]
[tex]Total = \$174.29[/tex]
By comparison, they will spend less at the sunny side hotel.
