Teachers and principles probably still want to keep school a little old fashioned while still having little technology by the next year or 2 we'll might not have to carry heavy backpacks anymore I wish you the best of luck.
Answer: a ticket to the movie costs $8.5
Step-by-step explanation:
Let x represent the cost of a movie ticket.
Let y represent the cost of a Soda.
Janice bought 3 movie tickets and 3 sodas and the total cost was $35.25. This means that
3x + 3y = 35.25 - - - - - - - - - -1
A ticket to the movie cost $5.25 more than a soda. This means that
x = y + 5.25
Substituting x = y + 25 into equation 1, it becomes
3(y + 5.25) + 3y = 35.25
3y + 15.75 + 3y = 35.25
6y = 35.25 - 15.75 = 19.5
y = 19.5/6 = 3.25
x = y + 5.25 = 3.25 + 5.25
x = 8.5
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a, b are real numbers.
Given the complex number z = 1 + 3i
In polar form: r = √(1² + 3²) = 3.16
Ф = tan⁻¹ (3/1) = 71.57⁰
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]

Answer:
0
Step-by-step explanation:
because we can't multiply anything by 0.
is like saying 0×0×0×0=0
Hope this helps :D
- 4x^2y * 3xy^3
multiply the numbers : 4*3 = 12
-12x^2xy^3y
apply exponent rule : x^2x = x^2+1 = x^3
-12x^3y^3y
apply exponent rule again : y^3y = y^1+3 = y^4
answer : -12x^3y^4
