What is multiplication?The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.
First, let's calculate the total number of dog biscuits that Jim has bought:
= 6 bags × 27 biscuits per bag
= 162 biscuits
Next, let's calculate how many biscuits the dog will eat in 4 weeks:
= 4 weeks × 5 biscuits per day
= 20 biscuits per week
20 biscuits per week × 4 weeks = 80 biscuits
So, Jim has bought 162 biscuits and his dog will eat 80 biscuits in 4 weeks. This means that Jim has brought enough dog biscuits for his dog for 4 weeks.
162 biscuits ≥ 80 biscuits

What are all the solutions to the equation sin 2x = 2cos x in the interval [0, 2π)?
Answers
Answer:
[tex]x=\dfrac{1}{2} \pi, \dfrac{3}{2} \pi \quad \textsf{in the interval}\:[0,2 \pi)[/tex]
Step-by-step explanation:
Rewrite the given equation so that it equals zero, using the trig identity:
[tex]\sin(2x)=2\sin(x)\cos(x)[/tex]
[tex]\begin{aligned}\sin(2x) & =2\cos(x)\\\sin(2x)-2\cos(x) & =0\\2\sin(x)\cos(x)-2\cos(x) & =0\\2\cos(x)[sin(x)-1] & =0\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Therefore}:\quad 2\cos(x) & =0\\\cos(x) & =0\\x & =\dfrac{1}{2} \pi \pm 2 \pi n, \dfrac{3}{2} \pi \pm 2 \pi n\end{aligned}[/tex]
[tex]\begin{aligned}\textsf{Therefore}:\quad \sin(x)-1 & =0\\\sin(x) & =1\\x & =\dfrac{1}{2} \pi \pm 2 \pi n\end{aligned}[/tex]
[tex]\implies x=\dfrac{1}{2} \pi, \dfrac{3}{2} \pi \quad \textsf{in the interval}\:[0,2 \pi)[/tex]
An equation is formed of two equal expressions. The value of x for which the sin(2x) = 2cos(x) will have solution in the interval [0, 2π) is (π/2) and (3π/2).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The equation can be rewritten as,
sin(2x) = 2 cos(x)
2 sin(x) cos(x) = 2 cos(x)
2 sin(x) cos(x) - 2 cos(x) = 0
Taking 2cos(x) as common,
2 cos(x) [sin(x) - 1] = 0
Now, the two factors can be written as,
cos(x) = 0
x = (π/2)±2πn, (3π/2)±2πn
sin(x) - 1 = 0
sin(x) = 1
x = (π/2)±2πn
Hence, the value of x for which the sin(2x) = 2cos(x) will have solution in the interval [0, 2π) is (π/2) and (3π/2).

1. Jackie is saving money to buy a new cell phone. The cell phone costs $175, but she has
already saved $56. What percent of the cost of the cell phone has Jackie saved?
Answers
Answer:
32%
Step-by-step explanation:
Given that:Jackie is saving money to buy a new cell phone.The cell phone costs $175 she has already saved $56To find:The percent of the cost of the cell phone has Jackie savedIn order to find the percent of the cost of the cell phone has Jackie saved,
divide the cost of the cell phone by the amount of the money Jackie savedMultiply the result (1) by 100See below how it's done:
[tex] \dfrac{56}{175} \times 100[/tex]
dividing yields:
[tex] 0.32 \times 100[/tex]
multiplying yields:
[tex]32\%[/tex]
Alternative:
Instead of dividing,we can consider reducing the fraction and multiply that with 100 to get the answer.
[tex] \dfrac{56}{175} \times 100 \\ \implies \frac{8}{25} \times 100 \\ \implies 8 \times 4 \\ \implies \boxed{32\%}[/tex]
In conclusion:

A triangle is a polygon. The total area of the figure can be represented by 12a, (6a+b), and 2b cm².
What is a triangle?A triangle is a polygon with 3 sides and 3 vertices.
Since the area of a single triangle is a cm², and the shape is formed of 12 triangles, therefore, the area of the 12 triangles will be equal to,
[tex]\text{Area of the complete figure} = 12 \times a = 12a\rm \ cm^2[/tex]
Given that the area of the complete dark portion is b cm², therefore, the area of the 6 triangles with a cm² of area each, and the black portion can be written as,
[tex]\text{Area of the complete figure} = (6 \times a)+b = (6a+b)\rm \ cm^2[/tex]
As the dark portion also consists of 6 triangles with an area of a cm² each and the total sum of this dark area is b cm². Also, the light portion consists of 6 triangles with an area of a cm². Therefore, the total area can be written as,
[tex]\text{Total area} = 6a+6a = b+b = 2b\rm\ cm^2[/tex]
Thus, the total area of the figure can be represented by 12a, (6a+b), and 2b cm².

Which trigonometric functions are positive in which quadrant?In first quadrant (0 < θ < π/2), all six trigonometric functions are positive.In second quadrant(π/2 < θ < π), only sin and cosec are positive.In the third quadrant (π < θ < 3π/2), only tangent and cotangent are positive.In fourth (3π/2 < θ < 2π = 0), only cos and sec are positive.(this all positive negative refers to the fact that if you use given angle as input to these functions, then what sign will these functions will evaluate based on in which quadrant does the given angle lies.)
Here, the given function is:
[tex]y= 3\cos(2(x + \pi/2)) - 2[/tex]
The options are:
[tex]y= 3\sin(2(x + \pi/4)) - 2[/tex][tex]y= -3\sin(2(x + \pi/4)) - 2[/tex][tex]y= 3\cos(2(x + \pi/4)) - 2[/tex][tex]y= -3\cos(2(x + \pi/2)) - 2[/tex]Checking all the options one by one:
Option 1: [tex]y= 3\sin(2(x + \pi/4)) - 2[/tex][tex]y= 3\sin(2(x + \pi/4)) - 2\\y= 3\sin (2x + \pi/2) -2\\y = -3\cos(2x) -2\\y = 3\cos(2x + \pi) -2\\y = 3\cos(2(x+ \pi/2)) -2[/tex]
(the last second step was the use of the fact that cos flips its sign after pi radian increment in its input)
Thus, this option is same as the given function.
This option if would be true, then from option 1 and this option, we'd get:
[tex]-3\sin(2(x + \pi/4)) - 2= -3\sin(2(x + \pi/4)) - 2\\2(3\sin(2(x + \pi/4))) = 0\\\sin(2(x + \pi/4) = 0[/tex]
which isn't true for all values of x.
Thus, this option is not same as the given function.
Option 3: [tex]y= 3\cos(2(x + \pi/4)) - 2[/tex]The given function is [tex]y= 3\cos(2(x + \pi/2)) - 2 = 3\cos(2x + \pi) -2 = -3\cos(2x) -2[/tex]
This option's function simplifies as:
[tex]y= 3\cos(2(x + \pi/4)) - 2 = 3\cos(2x + \pi/2) -2 = -3\sin(2x) - 2[/tex]
Thus, this option isn't true since [tex]\sin(2x) \neq \cos(2x)[/tex] always (they are equal for some values of x but not for all).
Option 4: [tex]y= -3\cos(2(x + \pi/2)) - 2[/tex]The given function simplifies to:[tex]y= 3\cos(2(x + \pi/2)) - 2 = 3\cos(2x + \pi) -2 = -3\cos(2x) -2[/tex]
The given option simplifies to:
[tex]y= -3\cos(2(x + \pi/2)) - 2 = -3\cos(2x + \pi ) -2\\y = 3\cos(2x) -2[/tex]
Thus, this function is not same as the given function.
Thus, the function which is same as the function y = 3cos(2(x +π/2)) -2 is: Option A: y= 3sin(2(x + π/4)) - 2

x° = 45°
y° = 90°
z° = 45°
Step-by-step explanation:
Angles on a straight line add up to 180°
⇒ z° + 135° = 180°
⇒ z° = 180° - 135°
⇒ z° = 45°
The dashes on the side lengths mean that the sides are of equal length. Therefore this is an isosceles triangle. The base angles of an isosceles triangle are equal.
⇒ x° = z°
⇒ x° = 45°
The sum of the interior angles of a triangle is 180°
⇒ x° + y° + z° = 180°
⇒ 45° + y° + 45° = 180°
⇒ y° = 180° - 45° - 45°
⇒ y° = 90°

Step-by-step explanation: This is because out of the total number of students taking math (95), 52 of such students are also taking science. In order to get the number of students only taking math you have to do 95-52=43 and to put that against the amount of total students the ratio would be 43:147 or 42/147 and if you plug 42/147 into a calculator you will recieve a long decimal that you can then round to 29%.

The maximum possible number to 2 d.p that will be 3.74 as the 4 keeps it at 3.7.
But someone can say 3.749 is a bigger number that 3.74 that will get rounded to 3.7
