The guy above me is most likel correct

Answer:

The horizontal line is the x axis

the vertical line is the y axis

The first number is always the number of the x axis

Example.

(6,9)

6 is in the x axis

9 is in the y axis

find the number 6 in the x axis (the horizontal one) and then go up until the number 9.

Answer:

22x - 14

Step-by-step explanation:

pretty sure its like this..

3(4x-3)+5(2x-1)

= 3×4x + 3×(-3) + 5×2x + 5×(-1)

= 12x + (-9) + 10x + (-5)

and according to the rules of multiplying negative by positive...

= 12x - 9 + 10x - 5

combine like terms using the symbols on its left

= 12x + 10x - 9 - 5

= 22x - 14

Answer:

53712.4

Explanation:

[tex]\sf\rightarrow 53.7124\:x\:10^3[/tex]

[tex]\sf\rightarrow 53.7124\:x\:1000[/tex]

[tex]\sf\rightarrow 53712.4[/tex]

Answer:

53712.4

Step-by-step explanation:

To represent this expression as a number, we need to simplify the expression to obtain a specific number (solution). The first step would be to simplify the exponent in the expression.

Simplifying the exponent:

⇒ 53.7124 x 10^{3}

⇒ 53.7124 x 10 x 10 x 10

Note: Each 10 will shift the decimal 1 place to the right.

⇒ 537.124 x 10 x 10

⇒ 5371.24 x 10

⇒ 53712.4

Answer:

A. ∠G ≅ ∠L   AND  B. ∠Q ≅ ∠V

Step-by-step explanation:

This is because the others although they are both initially opposite and seen as vertical they have a secondary line that alters the angle and so the last two angles that have this are not vertical

Answer:

738 cubic inches

Step-by-step explanation:

V=B*H

B=base area

H is height

82*9=738

The volume of the Prism is 738 cubic inches.

Prism is "3 dimensional shape with two identical shapes facing each other".

According to the question,

The base of prism (b) = 82 square inches.

The height of  prism (h) = 9 inches

Formula for Volume of prism = base of the prism × height of the prism

= 82 × 9

= 738 cubic inches.

Hence, the volume of the Prism is  738 cubic inches

Answer:

the cable is  2\sqrt{41} meters long

Step-by-step explanation:

after drawing out the lengths given, you can see that you need to find the hypotenuse of a triangle with legs 10 and 8 meters long.

10^2+8^2=164

sqrt of 164 is [tex]2\sqrt{41}[/tex]

Answer:

[tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)

Step-by-step explanation:

This can be modeled as a right triangle, with:

The length of the cable is the hypotenuse.

Using Pythagoras' Theorem: [tex]a^2+b^2=c^2[/tex]

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

[tex]\implies 8^2+10^2=c^2[/tex]

[tex]\implies 164=c^2[/tex]

[tex]\implies c=\sqrt{164}[/tex]

[tex]\implies c=\sqrt{4 \cdot 41}[/tex]

[tex]\implies c=\sqrt{4} \sqrt{41}[/tex]

[tex]\implies c=2\sqrt{41}\: \sf m[/tex]

Therefore, the length of the cable is [tex]2\sqrt{41}\: \sf m[/tex] = 12.81 m (nearest hundredth)

Answer:

A = picture attached

B = 51 in²

Step-by-step explanation:

The picture attached is the answer for part A. You use the dimensions you already know from the first picture to fill in the net of the slice of pie.

Area of the triangle = 1/2 (base × height)

A = 1/2 (4 × 6) = 1/2 (24) = 12

The area of the triangle is 12. The top is a triangle, but the bottom is also a triangle with the same area. Therefore, the area of the two triangles combined is 24 in². Next, we have to find the area of the rectangle at the sides of the pie.

Area of rectangle = length × width

A = 5 × 2.5 = 12.5

Since there are two rectangles with the same area on both sides of the pie, we can double it and get 25 in². We still have one rectangle left, the one at the back of the pie.

A = 6 × 2.5 = 15

Add the areas altogether to get the answer.

24 + 12.5 + 15 = 51.5 in²

I hope this helps. Sorry if Part B's answer is wrong.

Answer:

Let u = √x which gives u2= x and rewrite the given equation in terms of u

u = 3 - u 2 / 4

Multiply all terms by 4, simplify and write the above quadratic in standard form and solve it for u.

u 2 + 4 u - 12 = 0

Two solutions: u = - 6 and u = 2

Use the substitution used above u = √x to solve for x.

u = - 6 = √x has no solution

u = 2 = √x has solution x = 4

Below is shown the graph of the right side of the given equation when written with its right side equal to zero. The x intercept of the graph is the graphical solution to the equation as shown below.

Step-by-step explanation:

Answer: x = 4

Step-by-step explanation:

    Given:

√x = 3 - (1 / 4)x

    Rewrite:

[tex]\displaystyle \sqrt{x} = 3 - \frac{1}{4}x[/tex]

    Square both sides:

[tex]\displaystyle (\sqrt{x} )^{2} = (3 - \frac{1}{4} x)^{2}[/tex]

[tex]\displaystyle x= \frac{1}{16}x^{2} -\frac{3}{2} +9[/tex]

    Set the equation equal to 0:

[tex]\displaystyle \frac{-1}{16}x^{2} +\frac{5}{2} -9=0[/tex]

    Use the quadratic formula:

[tex]\displaystyle x=\frac{-b\sqrt{b^{2} -4ac} }{2a}[/tex]

[tex]\displaystyle x=\frac{-(\frac{5}{2})\sqrt{(\frac{5}{2})^{2} -4(\frac{-1}{16} )(-9)} }{2(\frac{-1}{16} )}[/tex]

x = 4, 36

    Plugging back into equation shows us only one answer works,

Step-by-step explanation:

Pythagorean theoreem: A^2 + B^2 = C^2

Now lets solve!!

5^2 + 5^2 = C^2

25 + 25 = c^2

Now we add!

25 + 25 = 50

Now we have to find the square root!!

[tex]\sqrt{50}[/tex] = 7

Have a nice day!!

Please rate and mark brainliest!!!

Answer:

x = 7

Step-by-step explanation:

All you do is use the Pythagorean theorem. The Pythagorean theorem states that A² + B² = C². The diagonal side is opposite to the 90-degree angle which means it's "C²". To find C², you add the 5² + 5² together (A² and B²). That equals 50. So C² = 50. To get rid of the square, you put the square root symbol over C² and 50. [tex]\sqrt{C^{2} } =\sqrt{50}[/tex]; C = [tex]\sqrt{50}[/tex]. You can simplify [tex]\sqrt{50}[/tex] to [tex]5\sqrt{2}[/tex] (Basically you find a square root that goes perfectly into 50 which was 25 and 2. The 25 would be canceled to 5 and the 2 would turn into [tex]\sqrt{2[/tex]). 5√2 is equal to 7.07 (Approximately). So the answer is 7.

Answer:

Step-by-step explanation:

To calculate the diagonal of a square, multiply the length of the side by the square root of 2 --> d = a√2

a² + a² = diagonal²

diagonal = √(a² + a²) = √(2 x a²) which simplifies to diagonal = a√2

If area is given --> d = √(2*area)

Knowing square perimeter --> d = (perimeter/4)*√2
