angle a = ___ degrees

Answer:

If the perimeter of a square is 28 inches and the area of the square is (x2 + 4x + 4) square inches, and x is a both a real and a positive number, then the value of x must be 5.

Step-by-step explanation:

All sides of a square are equal length.

The area of a square is the side length squared.

perimeter p, side length s, area a, and variable x.

p = 28.   s = ?   a = x^2 + 4x + 4.   x = ?

p = 28

p = 4s.

28 = 4s.

7 = s.

a = s^2.

s = 7.

a = 7^2.

a = 49.

a = x^2 + 4x + 4.

a = 49.

x^2 + 4x + 4 = 49.

factor x^2 + 4x + 4.

(x+2)(x+2) = 49.

(x+2)^2 = 49.

√ ((x+2)^2) = √49.

take positive answer.

x+2 = 7

x = 5.

Answer:

Volume = 434.89

Step-by-step explanation:

Answer.

Answer:

Half of 9.4 is 4.7

4.7^3(radius cubed) = 103.823

103.823 x 3.14(pi) = 326.00422

326.00422 x 4/3 = 434.672293333 rounded = 434.67

Step-by-step explanation:

Volume Of Sphere Formula:

4/3 x pi(3.14 or 22/7 OR ANY NUMBER depending on what they tell you to use for pi) x radius(half of your diameter or given radius)^3(cubed, to the power of 3)

4/3 x pi x radius cubed

Answer:

36 & 54

Step-by-step explanation:

By Question :-

Let :-

According to 1st condition :-

[tex]: \implies[/tex] x + y = 90

Answer:

[tex]y=-\frac{5}{3}x-\frac{16}{3}[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=\frac{3}{5} x +2[/tex]

From the given equation, we can see that [tex]\frac{3}{5}[/tex] is the slope of the line since it's in the place of m. Because perpendicular lines always have slopes that are negative reciprocals, the line we're currently solving for would have a slope of [tex]-\frac{5}{3}[/tex]. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-\frac{5}{3}x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=-\frac{5}{3}x+b[/tex]

Plug in the given point (-5,3)

[tex]3=-\frac{5}{3}(-5)+b\\3=\frac{25}{3}+b[/tex]

Subtract [tex]\frac{25}{3}[/tex] from both sides to isolate b

[tex]3-\frac{25}{3}=\frac{25}{3}+b-\frac{25}{3}\\-\frac{16}{3} = b[/tex]

Therefore, the y-intercept is [tex]-\frac{16}{3}[/tex]. Plug this back into [tex]y=-\frac{5}{3}x+b[/tex]

[tex]y=-\frac{5}{3}x+(-\frac{16}{3})\\y=-\frac{5}{3}x-\frac{16}{3}[/tex]

I hope this helps!

[tex]\triangle {UVW} \sim \triangle {UVA} \sim \triangle {UAW}[/tex]

Step-by-step explanation:

The triangles UVW, UVA and UAW, since all three are right angles and have the same combination of angles, meaning the existence of proportionality between corresponding lengths. That is:

[tex]UA \propto AV \propto UV[/tex], [tex]AW \propto UA \propto UW[/tex], [tex]UW \propto UV \propto WV[/tex]

Answer:

Net cash provided by operating activities = $135,800

Step-by-step explanation:

Given:

Net income = 89400

Accounts receivable decreased = 24000

Inventory increased = 14400

Issuance of long-term debt = 30000

Missing data;

Accounts payable decreased = $8,200

Equipment purchases = 100,000

Depreciation and amortization expense = $45,000

Find:

Net cash provided by operating activities

Computation:

Particular                                                        Amount

Net Income                                                 89400

Add Amortization                                        45000

Net income before non cash expenses 134400

Add Decrease in AR                                 24000

Less Increase in inventory                     14400

Less Decrease in AP                                  8200

Net cash provided by operating activities $135,800

Given:

The function is:

[tex]f(x)=-2x+1[/tex]

To find:

a. Slope and Y-intercept.

b. Is the function increasing, decreasing, or constant, justify your answer.

c. Graph the function, label x, and y-intercepts.

Solution:

a. We have,

[tex]f(x)=-2x+1[/tex]                  ...(i)

The slope intercept form of a line is:

[tex]y=mx+b[/tex]                    ...(ii)

Where, m is the slope and b is the y-intercept.

On comparing (i) and (ii), we get

[tex]m=-2,b=1[/tex]

Therefore, the slope of the line is -2 and the y-intercept is 1.

b. If the slope of a linear function is negative, then the function is decreasing.

If the slope of a linear function is positive, then the function is increasing.

If the slope of a linear function is 0, then the function is constant.

The slope of the linear function is negative.

Therefore, the function is decreasing.

c. We have,

[tex]f(x)=-2x+1[/tex]

At [tex]x=0[/tex], we get

[tex]f(0)=-2(0)+1[/tex]

[tex]f(0)=1[/tex]

So, the y-intercept is at (0,1).

At [tex]f(x)=0[/tex], we get

[tex]0=-2x+1[/tex]

[tex]2x=1[/tex]

[tex]x=\dfrac{1}{2}[/tex]

[tex]x=0.5[/tex]

So, the x-intercept is at [tex]\left(0.5,0\right)[/tex].

Plot the points [tex](0,1), \left(0.5,0\right)[/tex] and connect them by a straight line as shown below:

Answer:

x = - 1, x = [tex]\frac{1}{3}[/tex]

Step-by-step explanation:

Given

3x² + 2x - 1 ( to find the zeros, equate to zero )

3x² + 2x - 1 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × - 1 = - 3 and sum = + 2

The factors are + 3 and - 1

Use these factors to split the x- term

3x² + 3x - x - 1 = 0 ( factor first/second and third/fourth terms )

3x(x + 1) - 1 (x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(3x - 1) = 0

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x - 1 = 0 ⇒ 3x = 1 ⇒ x = [tex]\frac{1}{3}[/tex]

Answer:

x= 1/3, -1

Step-by-step explanation:

So you can solve this via graphing or solving, I will show both. By solving first you factor the equation and set it equal to 0 (this is because for x intercept y=0)

0 = (3x-1) (x+1)

Use math to solve for x,

3x-1=0

3x=1

x=1/3

(not sure if your teacher wants 1/3 as decimal or fraction, if decimal then use 0.333 in place of 1/3)

x+1=0

x= -1

As far as graphing, just plug the equation in Desmos and wherever the graph cross the x axis is where y values are 0 (which are the x intercepts) and you get the same value.

Answer:

y= 35⁰

x = 55⁰

Step-by-step explanation:

total angle of triangle is 180⁰

therefore we can equate:

x + (x-20) + 90 = 180

2x + 70 = 180

x = 55⁰

total of x and y is equal to 90⁰ since it is a right angle;

x + y = 90

x = 55⁰

55⁰ + y = 90

y = 35⁰

Answer:

Step-by-step explanation:

The two diagonal lines cross at the center point so each section of the lines are identical:

3x + 3 = 4x -4

Add 4 to both sides:

3x + 7 = 4x

Subtract 3x from both sides:

X = 7

The answer is x = 7

Answer:

x = 7

Step-by-step explanation:

KU = UM

as the center of a rectangle bisects the diagonal

Answer: the answer is either e or d but I guessed d

Step-by-step explanation:

The equivalent set to set S will be {12, 16, 20, ..., 36} thus, option (E) is correct.

A set is a collection of distinct values where each variable's meaning must be the same.

For instance, the set of natural numbers 1, 2, 3, 4, 5, and 6 is made up of variables that each represent a different natural number.

As per the given,

x is the multiple of 4,

4,8,12..

But is it restricted in the domain as, 9 ≤ x < 37

Thus, {12, 16, 20, ..., 36} will be correct.

Hence "The equivalent set to set S will be {12, 16, 20, ..., 36}".

Step-by-step explanation:

Given the expression;

5+2√3/7+4√3

Rationalize

5+2√3/7+4√3 * 7-4√3/7-4√3

= 35 - 20√3+14√3 - 24/49 - 16(3)

= 35 - 20√3+14√3 - 24/49 - 48

= 35 - 20√3+14√3 - 24

= 35 - 6√3- 24

= 35 - 24 -  6√3

= 11 - 6√3
