Answer:

x=15 cm

Step-by-step explanation:

The two triangles in the diagram are:

ABC and BDC

First we have to find the third side (hypotenuse) of BDC so that we can use it to find the value of x.

Hypotenuse is the largest side of a triangle which is usually in front of the right angle.

So in BDC

[tex]Base = BD =10cm\\Hypotenuse = BC = ?\\Perpendicular = CD = 2\sqrt{11}cm[/tex]

Applying Pythagoras theorem:

[tex](Hypotenuse)^2 = (Base)^2 + (Perpendicular)^2\\BC^2 = BD^2 + CD^2\\BC^2 = (10)^2 + (2\sqrt{11})^2\\BC^2 = 100+(2^2 * 11)\\BC^2 = 100+(4*11)\\BC^2 = 100+44\\BC^2 = 144\\\sqrt{BC^2} = \sqrt{144}\\BC = 12cm[/tex]

Solving for triangle ABC

[tex]Base = BC = 12 cm\\Perpendicular = AB = 9 cm\\Hypotenuse = AC = x\\[/tex]

Applying Pythagoras theorem

[tex]AC^2 = BC^2+AB^2\\x^2 = (12)^2 + (9)^2\\x^2 = 144+81\\x^2 = 225\\\sqrt{x^2} = \sqrt{225}\\x = 15cm[/tex]

Hence,

x=15 cm

Answer:

14 1/3

Step-by-step explanation:

First, you need to do what's in the parenthesis by finding a common denominator, which is 6. Multiply the 1 by 2 because that is what you multiply 3 by to get 6. You end up with 8 7/8 + 5 3/6. You then have to find the common denominator again, which is 24. Now the problem is 8 21/24 + 5 12/24. you get 13 32/24, which is equal to 14 8/24. Simplify, and you have 14 1/3.

Answer:

y = 1/4

Step-by-step explanation:

y⁻⁴ = 256

(1/y)⁴ = 256

y⁴ = 1/256

y =  ⁴√1/256

y = 1/4

Thus, The value of y is 1/4

Answer:

Percent Change is 16%

The change is increased.

Step-by-step explanation:

The original amount = 25

Amount increase = 4

We need to find percent increase

The formula used is: [tex]\frac{Amount \ increased}{Original \ Amount}*100[/tex]

Putting values in formula

[tex]Percent \ Change = \frac{Amount \ increased}{Original \ Amount}*100\\Percent \ Change =\frac{4}{25}*100\\Percent \ Change =16 \%[/tex]

So, Percent Change is 16%

The change is increased.

Answer:

The slope of line is 0 given points (2,8)(7,8)

Step-by-step explanation:

We need to find slope of line given points (2,8),(7,8)

The formula used to find slope of line is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We are given:

[tex]x_1=2, y_1=8, x_2=7 \ and \ y_2=8[/tex]

Finding slope using formula:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{8-8}{7-2}\\Slope=\frac{0}{5}\\Slope=0[/tex]

So, the slope of line is 0

Answer:

Step-by-step explanation:

The sides of a parallelogram are equal. If O is the midpoint of its diagonal AC, them AO+OC = AC

Given

AO = 4x + 12 and

OC = 5x – 6

Required

AC

AC = 4x+12 + 5x-6

AC = 4x+5x+12-6

AC = 9x+6

Hence the length of AC is 9x+6

Answer:

[tex]S(x) = x + \frac{1}{x}[/tex] --- Objective function

Interval = [tex]\{x:x=1\}[/tex]

Step-by-step explanation:

Given

Represent the number with x

The required sum can be represented as:

[tex]x + \frac{1}{x}[/tex]

Hence, the objective function is:

[tex]S(x) = x + \frac{1}{x}[/tex]

To get the the interval, we start by differentiating w.r.t x

Using first principle, this gives:

[tex]S'(x) = 1 - \frac{1}{x^2}[/tex]

Equate S'(x) to 0 in order to solve for x

[tex]0 = 1 - \frac{1}{x^2}[/tex]

Subtract 1 from both sides

[tex]0 -1 = 1 -1 - \frac{1}{x^2}[/tex]

[tex]-1 = - \frac{1}{x^2}[/tex]

Multiply both sides by -1

[tex]1 = \frac{1}{x^2}[/tex]

Cross Multiply

[tex]x^2 * 1 = 1[/tex]

[tex]x^2 = 1[/tex]

Take positive square root of both sides because x is positive

[tex]\sqrt{x^2} = \sqrt{1[/tex]

[tex]x = 1[/tex]

Representing x using interval notation, we have

Interval = [tex]\{x:x=1\}[/tex]

To get the smallest sum, we substitute 1 for x in [tex]S(x) = x + \frac{1}{x}[/tex]

[tex]S(1) = 1 + \frac{1}{1}[/tex]

[tex]S(1) = 1 + 1[/tex]

[tex]S(1) = 2[/tex]

Hence, the smallest sum is 2

Answer:

x = -3

Step-by-step explanation:

First solve it:

Subtract the x's from both sides

2y = -3x +8

2y = -5x +2

Divide by two

y= -1.5x + 4

y = -2.5x +1

set them equal to each other:

-1.5x +4 = -2.5x +1

Add 2.5 x to both sides

1x +4 = 1

x +4 = 1

subtract 4 from both sides

x = -3

Answer:

rise, run

Step-by-step explanation:

When finding the slope of a line using a slope triangle, the RISE length is divided by the RUN length. (I think. Sometimes the "divided by" makes me confused about which is on top, but I'm pretty sure this is right.)

Answer:  First You Have To Simplify The Equation From Both Sides Then Thats how You Will Determine what f is. F = -15

Variable [tex]f[/tex] is isolated as [tex]\boldsymbol{f=-15}[/tex] in the expression [tex]\frac{f}{3}+22=17[/tex].

A variable is a symbol and placeholder for a changing amount or any mathematical object.

An algebraic expression is one that is composed of integer constants, variables, and algebraic operations.

Given expression is [tex]\frac{f}{3}+22=17[/tex]

Transpose [tex]22[/tex] to the right side of the equation.

[tex]\frac{f}{3}=17-22\\\frac{f}{3}=-5[/tex]

[tex]f=-15[/tex]

So, variable [tex]f[/tex] is isolated as [tex]\boldsymbol{f=-15}[/tex]
