A triangle has sides with length in centimeters that are consecutive even integers. Find the lengths if the perimeter is 186cm?

Is that fan made or not-

Answer:

We want to rewrite:

sin^4(x)

in a way that only involves the first power of the cosine function.

We know that:

sin^2(x) = 1 - cos^2(x)

Then:

sin^4(x) = sin^2(x)*sin^2(x) = sin^2(x)*(1 - cos^2(x))

Now we know that:

cos(2x) = cos^2(x) - sin^2(x)

then

cos(2x) + sin^2(x) = cos^2(x)

We can replace that in our equation to get:

sin^2(x)*(1 - cos^2(x)) =  sin^2(x)*(1 - cos(2x) - sin^2(x) )

sin^2(x)*(1 - cos(2x) - sin^2(x) ) = sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

then:

sin^4(x) =  sin^2(x) - sin^2(x)*cos(2x) - sin^4(x)

sin^4(x) + sin^4(x) =   sin^2(x) - sin^2(x)*cos(2x)

2*sin^4(x) =  sin^2(x) - sin^2(x)*cos(2x)  = sin^2(x)*(1 - cos(2x))

sin^4(x) = sin^2(x)*(1 - cos(2x))/2

So we rewrite the equation in such a way that we only have the first power of the cosine function.

Answer:

$36.38

Step-by-step explanation:

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?

Given data

Tax= 7%

Cost = $34

Let us solve for the amount of tax

=7/100*34

=0.07*34

=2.38

Hence the total is =2.38+34

=$36.38

Answer:

14/18

Step-by-step explanation:

Answer:

Solution is x=4 and y=1.

Step-by-step explanation:

We are given with 4 x-5 y=11

And 8 x - 5 y =27

Let's solve them using elimination method.

Subtract the equations to get rid the 'y' terms. Or, multiply the second equation and add them together.

4 x -5 y =11

-8 x+5 y =-27

----------------------

-4x =-16

Divide both sides by -4.

x =4.

Now, plug in x as 4 into any of the given equations to find the corresponding y.

4(4) -5 y =11

16 -5 y =11

Subtract both sides 16.

-5y =-5

Divide both sides by -5

y=1

Answer:

x = 25

Step-by-step explanation:

Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is

4x - 30 = 2x + 20 ( subtract 2x from both sides )

2x - 30 = 20 ( add 30 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25

Step-by-step explanation:

x=11

=> X - 2 = -8

=> X=(-6) - 2

=> -8

Answer:

x = -6

Step-by-step explanation:

x - 2 = -8

Add 2 to both sides to isolate the variable, x.

x - 2 + 2 = -8 + 2

-2+2 = 0

-8+2 = -6

Therefore,

x = -6

Check:

-6 -2 = -8

Hope this helps

Answer:

Infinitely many solutions.

Step-by-step explanation:

Multiply the second equation by -2, then add the equations together

(20x+2y=18)

−2(10x+y=9)  

20x+2y=18

−20x−2y=−18

Add these equations to eliminate x

0=0

Infinitely many solutions.

Answer:

The answer is "[tex]142,857 \times 6=857,142[/tex]"

Step-by-step explanation:

Please find the complete question in the attached file.

Let:

[tex]a b c d e f \times 6 = d e f a b c[/tex]

[tex]\to (10^5 a+10^4 b+10^3c+10^2d+10e+f) \times 6 =10^5d+10^4e+10^3f+10^2a+10b+c \\\\\to ( 6 \times 10^5 a+ 6 \times 10^4 b+6 \times 10^3c+ 6 \times 10^2d+ 6 \times 10e+ 6 \times f) =10^5d+10^4e+10^3f+10^2a+10b+c \\\\\to 600,000a+60,000b+6,000c+600d+60e+6f=100,000d+10,000e+1,000f+100a+10b+c \\\\\to 599,900a+59,990b+5999c=99,400d+9,940e+994f\\\\[/tex]

[tex]\to 7(599,900a+59,990b+5999c)=7(99,400d+9,940e+994f)\\\\\to 85,700a+8,570b+857c=14,200d+1420e+142f\\\\\to 857(100a+10b+c)=142(100d+10e+f)\\\\\to \frac{(100a+10b+c)}{(100d+10e+f)}=\frac{142}{857}\\\\\to \frac{abc}{142}=\frac{de f}{857}\\[/tex]

therefore 142 and 857 are mutually exclusive, so, the only possible way is:

[tex]\to a=1; b=4; c=2; d=8; e=5; f=7 \\\\ \therefore \\\\ \to 142,857 \times 6=857,142[/tex]

Answer:

700

Step-by-step explanation:

35 m = 3500 cm

3500 cm ÷ 5 cm = 700

y intercept is where x=0 or the initial value

which is 60 because we gots

y=60(1)

y=60

y intercept is at y=60

8 years is x=8

y=82.114

round

y=82.11

answer:

y intercept is y=60

after 8 years, has $82.11

Answer:

y = -40x+2600

Step-by-step explanation:

Writing the values as coordinate (m, s)

If after flying for 11 seconds, he is 2160 meters from her, the required coordinate is (11, 2160)

Then at 19 seconds he is 1840 meters, the required coordinate is (19, 1840)

Get the slope;

m = 2160-1840/11-19

m = 320/-8

m = -40

Substitute m = -40 and (11, 2160) into the equations;

y-y0 = m(x-x0)

y -2160 = -40(x-11)

y - 2160 = -40x+440

y = -40x+440 + 2160

y = -40x+2600

Hence the requires equation is y = -40x+2600

Answer:

area of figure=11×2+4×2=22+8=30m²

Answer:

(-2, -1, 0, 3,3)

Step-by-step explanation:

The domain simply refers to the possible x-values the function can take

so by listing out all the x-values of the individual points, we have all the domains

That will be ;

(-2, -1, 0, 3,3)

Answer:

y=2x

Step-by-step explanation:

So it meets the y axis at 0 to there is no y intercept needed to be put into the equation

The line goes up by 2 and across by 1 so the gradient = 2/1 = 2

So: y = 2x
