Step-by-step explanation:
determine the general solution of -4sinx = 5cosx
Step-by-step explanation:
Divide both sides by cosine to get:
[tex] - 4tan(x) = 5[/tex]
Divide both sides by -4 to get:
[tex]tan(x) = - \frac{5}{4} [/tex]
Take the arctangent of both sides to get:
[tex]x = arctan( - \frac{5}{4} )[/tex]
Plus any integer rotation of pi (180 degrees)
Which equation is the inverse of 5 y 4 = (x 3) squared one-half? y = one-fifth x squared six-fifths x eleven-tenths y = 3 plus-or-minus startroot 5 x seven-halves endroot negative 5 y minus 4 = negative (x 3) squared minus one-half y = negative 3 plus-or-minus startroot 5 x seven-halves endroot
The inverse function of the function 5y + 4 = (x + 3)² + 0.5 is shown below. Then the correct option is D.
[tex]\rm y= \pm \sqrt{5x + \dfrac{7}{2}} - 3[/tex]
What is the inverse of a function?Suppose that the given function is
[tex]f:X\rightarrow Y[/tex]
Then, if function 'f' is one-to-one and onto function (a needed condition for inverses to exist), then, the inverse of the considered function is
[tex]f^{-1}: Y \rightarrow X[/tex]
such that:
[tex]\forall \: x \in X : f(x) \in Y, \exists \: y \in Y : f^{-1}(y) \in X[/tex]
(and vice versa).
It simply means, the inverse of 'f' is a reverse operator, that takes back the effect of 'f'
The equation is given below.
[tex]\rm 5y + 4 = (x+3)^2 + \dfrac{1}{2}[/tex]
Then y will be
[tex]\rm 5y = (x+3)^2 + \dfrac{1}{2} - 4\\\\\rm y \ \ = \dfrac{(x+3)^2}{5} - \dfrac{7}{10}[/tex]
The replace y by x and x by y, then we have
[tex]\begin{aligned} x &= \dfrac{2(y+3)^2}{10} - \dfrac{7}{10}\\\\\dfrac{10x + 7}{2} &= (y + 3)^2 \\\\\sqrt{5x + \dfrac{7}{2}} &= y + 3\\\\y &= \pm \sqrt{5x + \dfrac{7}{2}} - 3 \end{aligned}[/tex]

Answer: D
Step-by-step explanation:
The 2022 Russian Invasion of Ukraine began due to the cause of the collapse of the Soviet Union, which was sped along by the independence of the baltic states in 1990. When Ukraine left the USSR in 1991 and gave it's nuclear weapons to Russia in 2006, it began clear that Ukraine needed to be returned back into the hands of Moscow, before becoming another frontline for the NATO Army to invade the Russian Federation from the west, with more support from Japan in the east. Oh and I did the Edge test in 2022 so thats how I know it's D.
A seamstress needs to cut 15-inch pieces of ribbon from a roll of ribbon that is 9 feet in length. What is the greatest number of 15-inch pieces the seamstress can cut from 5 of these rolls of ribbon
Answer:
35 strips :)
Step-by-step explanation:
1 foot; 12 inches
Now lets solve!!
12 x 9 = 108
Now we must divide :)
108/15 = 7
Since she has 5 rolls, we need to multiply 1 more time :)
7 x 5 = 35
Have an amazing day!!
Please rate and mark brainliest!!
Answer:
35
Step-by-step explanation:
1 foot = 12 inches
so (multiply both by 9)
9 feet = 108 inches
108 divided by 15 = 7.2
the .2 part can't be used, so each roll can make 7 pieces of ribbon
Theres 5 rolls of ribbon so multiply 7 by 5 which is 35

half hour = 30 mins
60 + 30 = 90 mins
90 min is less than 100 mins

What is a polynomial?Polynomial is an equation written with terms of the form kx^n.
where k and n are positive integers.
There are quadratic polynomials and cubic polynomials.
Example:
2x³ + 4x² + 4x + 9 is a cubic polynomial.
4x² + 7x + 8 is a quadratic polynomial.
We have,
To find the product of the polynomials (3x² - 2x - 3) (5x² + 4x + 5), we can use the distributive property of multiplication to multiply each term in the first polynomial by each term in the second polynomial, and then combine like terms.
We can start by multiplying the first term in the first polynomial, 3x^2, by each term in the second polynomial:
3x² (5x² + 4x + 5)
= [tex]15x^4 + 12x^3 + 15x^2[/tex]
Next, we multiply the second term in the first polynomial, -2x, by each term in the second polynomial:
-2x(5x² + 4x + 5) = -10x³ - 8x² - 10x
Finally, we multiply the third term in the first polynomial, -3, by each term in the second polynomial:
-3(5x² + 4x + 5) = -15x² - 12x - 15
Putting these three results together, we have:
(3x² - 2x - 3) (5x² + 4x + 5)
= [tex]15x^4 + 2x^3 - 3x^2 + 12x^2 - 10x^3 - 10x - 15x^2 - 12x - 15[/tex]
Simplifying and collecting like terms, we get:
(3x² - 2x - 3)(5x² + 4x + 5)
[tex]15x^4 - 8x^3 - 6x^2 - 22x - 15[/tex]
Therefore,
The product of the polynomials is [tex]15x^4 - 8x^3 - 6x^2 - 22x - 15.[/tex]

What is Graph?A graph contains data of which input maps to which output.
Analysis of this leads to the relations which were used to make it.
If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.
WE have given the graph shows the population of a city n months after the establishment of a new automobile plant in the city.
We can see that at 4000 people, the graph increases and then become constant at the rate of 7000 people.
So we can conclude that the population of the city increases rapidly for the first four months and then slowly approached 7000 people.

I have 35 quarters and dimes in
my pocket. How many of each do I have if I have $5.45??
HELP Me pls
Answer:
13 Quarters, 22 Dimes
Step-by-step explanation:
.10d + .25q = 5.45
.10 (35 - q) + .25q = 5.45
3.5 - 10q + .25q = 5.45
.25q - .10q = 5.45 - 3.5
.15q = 1.95
q = 13
Plug the value of q to solve for d, or the number of dimes.
d = 35 - q
d = 35 - 13
d = 22
