lol other person did the multiplication so i did the long way
The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Multiplication, Subtraction, Summation, and division.
As per the given numbers,2,4,6,8
Let's multiply 6 and 4
6 × 4 = 24
Now let's multiply 24 by 2
24 × 2 = 48
So, 6 × 4 × 2 = 48
Now we need to add only 12 to get 60 so, 8 + 4 = 12
So, 6 × 4 × 2 + 8 + 4 = 60
Hence "The arithmetic operation is used to make 60 by the number 2,4,6,8 with operation 6×4×2+8+4=60".

can i have the answer please
Answer:
x=0,4
Step-by-step explanation:
88-55+ 5x-7=180
Find the value of x
Answer:
x = 30.8
Step-by-step explanation:
88 - 55 + 5x -7 = 180
33 + 5x -7 = 180
5x -7 = 180 - 33
5x - 7 = 147
5x = 147 +7
5x = 154
x = 154/5
x = 30.8

If 5cos^2θ + 6sin^2θ =11/2
, the value of cosecθ =--------
Answer:
[tex]\csc(\theta)=\sqrt{2}[/tex]
Step-by-step explanation:
Please refer to the attachment below.
We have:
[tex]5\cos^2(\theta)+6\sin^2(\theta)=11/2[/tex]
Remember that cosine is the ratio of the adjacent side to the hypotenuse. Therefore:
[tex]\cos(\theta)=\frac{b}{c}[/tex]
And sine is the ratio of the opposite side to the hypotenuse. Therefore:
[tex]\sin(\theta)=\frac{a}{c}[/tex]
Substitute into our original equation:
[tex]5(\frac{b}{c})^2+6(\frac{a}{c})^2=11/2[/tex]
Square:
[tex]\frac{5b^2}{c^2}+\frac{6a^2}{c^2}=\frac{11}{2}[/tex]
Multiply both sides by c squared:
[tex]5b^2+6a^2=\frac{11}{2}c^2[/tex]
Let’s also multiply both sides by 2 to eliminate the fraction:
[tex]10b^2+12a^2=11c^2[/tex]
Remember that according to the Pythagorean Theorem:
[tex]c^2=a^2+b^2[/tex]
Hence, we can make another substitution:
[tex]10b^2+12a^2=11(a^2+b^2)[/tex]
Distribute:
[tex]10b^2+12a^2=11a^2+11b^2[/tex]
Subtract 10b² from both sides:
[tex]12a^2=11a^2+b^2[/tex]
Subtract 11a² from both sides:
[tex]a^2=b^2[/tex]
Take the square root of both sides:
[tex]a=b[/tex]
Hence, a is equivalent to b.
Then, we must have a 45-45-90 Triangle.
Therefore, our angle θ is 45°.
We can substitute this back into our original equation to make sure. Remember that cos(45)=sin(45)=√2/2:
[tex]\begin{aligned} 5\cos^2(45)+6\sin^2(45)&=11/2 \\ 5(\frac{\sqrt{2}}{2}})^2+6(\frac{\sqrt{2}}{2})^2&=11/2 \\ 5(2/4)+6(2/4)&=11/2 \\ 5(1/2)+6(1/2)&=11/2 \\ 5/2+6/2&=11/2 \\ 11/2&=11/2 \;\checkmark \end{aligned} \\[/tex]
Hence:
[tex]\begin{aligned} \sin(45)&=\frac{1}{\sqrt{2}} \\ \Rightarrow \csc(\theta)&=\sqrt{2} \end{aligned}[/tex]
Determine whether AB and CD are parallel, perpendicular,
or neither.
A (12,3), B(-3,9), C (-6,4), D (-2,-6)
Answer:
Step-by-step explanation:
we can find the equations for both lines and analyze after
[tex]y = mx + b\\where\\m = \frac{y_2-y_1}{x_2-x_1}\\\\[/tex]
AB:
[tex](12, 3), (-3, 9)\\m = \frac{9-3}{-3-12} = \frac{6}{-15} = \frac{-2}{5}[/tex]
[tex]y = \frac{-2}{5}(x) + b\\3= \frac{-2(12)}{5} + b\\3 = \frac{-24}{5} + b\\b = \frac{39}{5} \\y = \frac{-2}{5}(x) + \frac{39}{5}[/tex]
CD:
[tex](-6, 4) (-2, -6)\\m = \frac{4-(-6)}{-6-(-2)} = \frac{10}{-4} = \frac{-5}{2} \\y = \frac{-5}{2}(x) + b\\4 = \frac{-5(-6)}{2} + b\\4 = 15 + b\\b = -11\\y = \frac{-5}{2}(x) - 11[/tex]
Determining whether two lines are parallel or perpendicular involves looking at their slopes. AB has a slope of -2/5, CD has a slope of -5/2. Since these are not equal (not parallel) and not negative reciprocals of each other (not perpendicular), the lines are neither perpendicular or parallel.
