I need help with number 35

Answer:

122 feet

Step-by-step explanation:

We know that the length of the park is 65 feet long and the park is rectangular. Therefore we add 65+65 to find the total of both length sides.

65+65=130

Next we subtract 130 from the total amount of 374 to find the total of both width sides.

374-130=244

Now we divide what is left by 2 to find the width of an individual side.

244÷2=122

The width is 122.

Check your answer by inserting the numbers into the equation for perimeter.

P=2W+2L

374=(2×65)+(2×122)

374=130+244

374=374

Multiplication is the process of multiplying. The value of A-BC is equal to -19-17i.

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

The value of BC is,

BC = (4-2i)×(1+6i)

BC = 4 + 24i - 2i -12i²

BC = 4 + 22i - 12(-1)

BC = 4 + 22i +12

BC = 16 + 22i

Now, the value of A-BC will be equal to,

A-BC = (-3+5i)-(16+22i)

         = -3+5i-16-22i

         = -19 - 17i

Hence, the value of A-BC is equal to -19-17i.

Answer:

x = -1/3 or 0

Step-by-step explanation:

Given equation:

We can factor 12x on the L.H.S since 12x is divisible by 36x² and 12x.

[tex]\implies 36x^{2} + 12x = 0[/tex]

[tex]\implies 12x(3x + 1) = 0[/tex]

This can lead to two solutions. I have listed them below!

Divide 12x on both sides to open the parentheses.

[tex]\implies 12x(3x + 1) = 0[/tex]

[tex]\implies \dfrac{12x(3x + 1)}{12} = \dfrac{0}{12}[/tex]

Note: zero divided by any non-zero number is 0.

[tex]\implies \dfrac{12x(3x + 1)}{12} = \dfrac{0}{12}[/tex]

[tex]\implies 3x + 1 = 0[/tex]

Isolate 3x on one side of the equation.

[tex]\implies 3x + 1 = 0[/tex]

[tex]\implies 3x = 0 - 1[/tex]

[tex]\implies 3x = -1[/tex]

Divide 3 both sides to determine the value of x.

[tex]\implies 3x = -1[/tex]

[tex]\implies \dfrac{3x}{3} = \dfrac{-1}{3}[/tex]

[tex]\implies \boxed{x = \dfrac{-1}{3}}[/tex]

Divide (3x + 1) on both sides to isolate 12x.

[tex]\implies 12x(3x + 1) = 0[/tex]

[tex]\implies \dfrac{12x(3x + 1)}{(3x + 1)} = \dfrac{0}{(3x + 1)}[/tex]

Note: zero divided by any non-zero number is 0.

[tex]\implies \dfrac{12x(3x + 1)}{(3x + 1)} = \dfrac{0}{(3x + 1)}[/tex]

[tex]\implies 12x = 0[/tex]

Divide 12 both sides to determine the value of x.

[tex]\implies 12x = 0[/tex]

[tex]\implies \dfrac{12x}{12} = \dfrac{0}{12}[/tex]

[tex]\implies \boxed{x = 0}[/tex]

Therefore, the solutions for x are -1/3 or 0.

Answer:

x = 0  or  x = -1/3

Step-by-step explanation:

In the equation 36x²+12x=0 we have :

36x² = 6x × (6x)

12x = 2 × (6x)

This means that 6x is a common factor,so let’s factor :

36x²+12x=0

⇔ 6x × (6x) + 2 × (6x) = 0

⇔ 6x × (6x + 2) = 0

⇔ 6x = 0  or  6x + 2 = 0

⇔ x = 0  or  x = -2/6

Answer:

-4√5/9.

Step-by-step explanation:

if cos x = -2/3 then sin x = √(1 - (-2/3)^2)

= √(5/9)

= √5/3.

(As x is in quadrant 2 sin x is positive).

So:

sin2x = 2 sin x cos x

         = 2 * √5/3 * -2/3

          =  -4/3 * √5/3

          =  -4√5/9.

Experimental studies were the type of statistical study used by doctors in research on comparing placebo pills with real pills.

The study carried out is not appropriate for the statistical questions that must be answered, because telling patients about the pills introduces bias.

It is a method of scientific research in which there is the introduction of an intervention by the researchers, in which the resulting effects will be objects of study.

Therefore, in an experimental study there will be randomization of participants, who will be randomly grouped into a group to carry out the controlled trial.

215.625square feet

Step-by-step explanation:

area rectangle = l x w = 7.5x12.5

Answer:

Find the first and second derivatives:

[tex]\begin{aligned}f(x) & =-x-\dfrac{9}{x}\\& =-x-9x^{-1}\\\\\implies f'(x) & =-1-(-1)9x^{(-1-1)}\\ & =-1+9x^{-2}\\ & = -1+\dfrac{9}{x^2}\\\\\implies f''(x) & = 0+(-2)9x^{(-2-1)}\\& = -18x^{-3}\\& = -\dfrac{18}{x^3}\end{aligned}[/tex]

To find the stationary points (local minimum and maximum) set the first derivative to zero and solve for x:

[tex]\begin{aligned}f'(x) & = 0 \\\\\implies -1+\dfrac{9}{x^2} & = 0 \\\\\dfrac{9}{x^2} & = 1 \\\\9 & =x^2\\\\\implies x & = \pm 3\end{aligned}[/tex]

To determine the type of stationary points, input the found values of x into the second derivative.

[tex]f''(3)=-\dfrac{18}{3^3}=-\dfrac{2}{3} < 0 \implies \textsf{maximum}[/tex]

[tex]f''(-3)=-\dfrac{18}{(-3)^3}=\dfrac{2}{3} > 0 \implies \textsf{minimum}[/tex]

Finally, to find the y-values of the stationary points, input the found values of x into the original function:

[tex]f(3)=-3-\dfrac{9}{3}=-6 \implies (3,-6)[/tex]

[tex]f(-3)=-(-3)-\dfrac{9}{-3}=6 \implies (-3,6)[/tex]
