x = 9

Step-by-step explanation:

x² = 81

[tex]\sqrt{81} = 9[/tex]

9×9 = 81

x = 9

Answer:

Silly mistake haha I've been there. It would be 9 :)

Step-by-step explanation:

9x9 = 81 so 9^2 =81

If you had 3 then it would be 3x3=9 and 3^2= 9

Hi there!

[tex]\large\boxed{AB = 32.60 in}[/tex]

Find the length of AB by finding the length of its base:

We can use sine to solve for the length of the Hypotenuse of the triangle located in the base:

sin  = O / H

sin 50° = 24 / H

h * sin 50° = 24 ----> h = 24 / (sin 50°)

h ≈ 31.33 in

Use the Pythagorean Theorem to solve for the length of the diagonal since we have solved for the base of the triangle:

c² = a² + b²

c² = 31.33² + 9²

c² = 1062.57

c ≈ 32.60 in

AB = 32.60 in

The correct answer would be -3/8 or in decimal form -0.375 :)

9514 1404 393

Answer:

Step-by-step explanation:

The square of a binomial is ...

  (x +a)² = x² +2ax + a²

Comparing this to your expression, we have ...

  2a = 20 . . . . x-coefficient

  a² = c . . . . . . constant term

Then ...

  a = 20/2 = 10

  a² = 10² = 100 = c

The square is then ...

  (x +10)²

Answer:

c = 100 makes this a perfect square trinomial

Answer:

7500 N

Step-by-step explanation:

Given that,

A hammer claw moves a distance of 0.10 meters to remove a nail.

Resistance force, F = 1500 N

The person move the handle of the hammer 0.5 m

We need to find the effort force. Let it is F'. The mechanical advantage is given by :

[tex]m=\dfrac{effort}{resistance}=\dfrac{d_i}{d_o}[/tex]

Where [tex]d_i\ \text{and}\ d_o[/tex] are input and output distance respectively.

[tex]m=\dfrac{F'}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=\dfrac{0.1}{0.5}\\\\\dfrac{1500}{F}=0.2\\\\F=7500\ N[/tex]

So, the effort force is 7500 N.

Answer:

Pretty sure its undefined

Step-by-step explanation:

Answer:

Undefined

Step-by-step explanation:

Looking at the change in x's theres no variation which means this is a vertical line, thus therefore this is an undefined line as the rise over the run or the change in y over the change in x will result in a divide by 0 situation making it (-4, all real numbers) aka undefined.

slope = rise/run = change in y/change in x = (y2-y1)/(x2-x1)

Answer:

m<ACD = 90

m<CDB = 126

m<EDB = 54

m<CDE = 180

Step-by-step explanation:

Well you have the right girl! *In honors geometry you can trust me!

Ok first thing...We already know

B = 54

A = 90  

D = 54 (It's the Alternate interior angle of B)

C = 90

m<ACD = 90 (C = 90)

m<CDB = 126 (D = 54 ------> 180-54= 126)

m<EDB = 54 (Alternate Interior angle of B)

m<CDE = 180 (It is a straight line)

Answer:

y = 8x + 38

Step-by-step explanation:

To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)

   y = mx + b

   y = 8x + b

   6 = 8(-4) + b

   6 = -32 + b

+32   +32

 38 = b

So using our slope and our intercept we have our slope intercept

y = mx + b

y = 8x + 38

Hope this helps :)

Answer:

y - y1 = m(x - x1)

y - 6 = 8(x - (-4))

y - 6 = 8(x + 4)

y - 6 = 8x + 32

y = 8x + 32 + 6

y = 8x + 38

Step-by-step explanation:

First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.

After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.

Then you add 6 to both sides of the equation to isolate the y.

The slope-intercept equation ends up looking like this: y = 8x + 38

Hope this helps :)

Simplify the expression.

8x² + 8

Answer:

8(x^2 +1)

Step-by-step explanation:

(x^2 + 3)^2 - (x^2 - 1)^2

(x^2 + 3 - (x^2-1)) • (x^2 + 3 + (x^2 - 1))

(x^2 + 3 - x^2 + 1) • (x^2 + 3 + (x^2 - 1)

(3 + 1) • (x^2 + 3 + x^2 - 1)

4(2x^2 + 1)

4 • 2(x^2 + 1)

Answer:

MTD = 75

Step-by-step explanation:

RTD + RTM + MTD = 180

     65 + 40 + MTD = 180

            105 + MTD = 180

Subtract 105 from both sides.

                      MTD = 75

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle ∠MTD is equal to 15°.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."

Given that point M is in the interior of ∠RTD. Also, the measure of ∠RTM=40°, and ∠RTD = 65°.

Now, since the two angles together form ∠RTD, therefore, we can write,

∠RTD =  ∠RTM + ∠MTD

65° = 40° + ∠MTD

∠MTD = 65° - 40°

∠MTD = 15°

Hence, the measure of the angle ∠MTD is equal to 15°.

Answer:

there are two variables x and y which variable do u need to find or do u need it in point slope form

Answer:

Simplifying

6x + 3y = 54

Solving

6x + 3y = 54

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3y' to each side of the equation.

6x + 3y + -3y = 54 + -3y

Combine like terms: 3y + -3y = 0

6x + 0 = 54 + -3y

6x = 54 + -3y

Divide each side by '6'.

x = 9 + -0.5y

Simplifying

x = 9 + -0.5y

Answer: Sure,

Step-by-step explanation:

The form ax^2 + bx + c = 0 is called standard form of a quadratic equation. Before solving a quadratic equation using the Quadratic Formula, it's vital that you be sure the equation is in this form. If you don't, you might use the wrong values for a, b, or c, and then the formula will give incorrect solutions.
