y=4x + 1 what is the value of x=5 ?

Answer:

394.13 to 2 D.P.s

Step-by-step explanation:

Area = pi r^2

= 3.142 * 11.2^2

= 394.132.

The area of this circle up to 2 decimal places will be 394.13 square units.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

The radius of the circle is 11.2 units and takes π to be 3.142. Then the area is given as,

A = π x (11.2)²

A = 3.142 x 125.44

A = 394.13 square units

The area of this circle up to 2 decimal places will be 394.13 square units.

Answer:

128x + 288

Step-by-step explanation:

Given the expression 2^5(4×+9)

on factoring

2^5(4×+9) = 2^5(4x) + 2^5(9)

2^5(4×+9) = 32(4x) + 32(9)

2^5(4×+9) = 128x + 288

Hence the expression is also equivalent to 128x + 288

Answer:

AC=3x+11

Step-by-step explanation:

ok so AC is Both AB AND BC combined

2x-2+x+13=AC

3x+11=AC

AC=3x+11

Answer:

(2x-2) + (x+13)=6x+2 (take the lengths of AB and BC added together, and put equal to the value of AC)

3x+11 =6x+2 (drop the parenthesis and combine like terms on the left side)

-3x +11 =2 (subtract 6x from both sides and then subtract 11 from both sides)

-3x = -9 (divide both sides by -3 to find what x is)

x=3 (take the x value and plug it into the expression to find the length of AC)

6(3)+2 (multiply)

18+2 (add)

20 (this is the length of AC, and what you put in the box)

Explain how you found your answer:

Given:

The shape of box is a right triangular prism.

Paper cost = 2 cents per square centimeter

To find:

The cost to cover the entire box.

Solution:

In the given right triangular prism, we have 3 rectangle surfaces and 2 triangular surfaces.

Area of a rectangle is

[tex]Area=length\times width[/tex]

Area of rectangle with length 4 cm and width 3 cm is

[tex]A_1=4\times 3=12\text{ cm}^2[/tex]

Area of rectangle with length 4 cm and width 4 cm is

[tex]A_2=4\times 4=16\text{ cm}^2[/tex]

Area of rectangle with length 4 cm and width 5 cm is

[tex]A_3=4\times 5=20\text{ cm}^2[/tex]

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base\times height[/tex]

Area of triangle with base 3 cm and height 4 cm is

[tex]A_4=\dfrac{1}{2}\times 3\times 4[/tex]

[tex]A_4=\dfrac{12}{2}[/tex]

[tex]A_4=6\text{ cm}^2[/tex]

Bottom and top triangular surfaces are equal.

[tex]A_5=A_4=6\text{ cm}^2[/tex]

Now, total surface area of the box is

[tex]A=A_1+A_2+A_3+A_4+A_5[/tex]

[tex]A=12+16+20+6+6[/tex]

[tex]A=60\text{ cm}^2[/tex]

Paper cost = 2 cents per square centimeter

Cost of 60 square centimeter paper is

[tex]60\times 2=120\text{ cents}[/tex]

Therefore, the cost to cover the entire box is 120 cents or $1.2.

Answer:

The relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Step-by-step explanation:

Consider the relation

[tex]y^{2} - 4x = 3[/tex]

[tex]y=\pm \sqrt{4x+3}[/tex]

Thus, the equation [tex]y=\pm \sqrt{4x+3}[/tex] does not represent function because there is at least one x-value with two or more values.

For example, if you look at the attached graph,

at x = 0, y = 1.73

at x = 0 , y = -1.73

It means the same input is generating two outputs; also if we draw a vertical line on the graph, the vertical line would intersect the graph more than once.

Please check the red vertical line on the graph would intersect the graph more than once.

Therefore, the relation [tex]y^{2} - 4x = 3[/tex] does not represent y as a function of x.

Step-by-step explanation:

The term 9x is comprised of two values: 9 and x. The 9 represents the cost of the general admission tickets. Since the expression is representing the total cost for the group of friends, the number of friends attending must be represented somehow in the equation. Since the $9 is paired with the x, this means that x represents how many of the friends are paying the general admission price. After interpreting both values within the term, the meaning of the term 9x is simply just the total cost of the friends that are paying the general admission price! Hope this helps!

Answer:

similarity

Step-by-step explanation:

look , dude

the two triangles have the following features:

the angle B= angle C = 90 degree

the angle A= the angle F

so  the third angle in the first triangle = the third angle in the second triangle

so you have one condition of similarity which is the three angles are equal

to get the answer for lengths :

ab/fe= constant of proportionality

thus ab/fe=2.5/5=.5

so ac/13=.5 thus ac=6.5

and 6/de=.5 so de=12

Both similarity and Pythagorean theorem can be used to find the missing lengths as AC = 6.5 and DE = 12.

Similar triangles are those triangles which has the same shape but different size.

The length of sides and angles are proportional in similar triangles.

Pythagorean theorem states that for a right angled triangle,

Hypotenuse² = Base² + Altitude²

AC² = BC² + AB²

AC² = 6² + 2.5²

AC² = 42.25

AC = √(42.25) = 6.5

Similarly,

DF² = DE² + EF²

13² = DE² + 5²

DE² = 13² - 5²

DE² = 144

DE = √(144) = 12

If we are using the concept of similarity, ratio of corresponding sides are equal for similar triangles.

AB / EF = BC / DE = AC / DF

2.5 / 5 = 6 / DE = AC / 13

Consider 2.5 / 5 = 6 / DE

Then DE = (6 × 5) / 2.5 = 12

Consider AB / EF = AC / DF

2.5 / 5 = AC / 13

AC = (2.5 / 5) × 13 = 6.5

Hence the missing lengths are AC = 6.5 and DE = 12.

The domain is the x values involved in the equation/graph. The lines seemingly goes from -5 to 6. The x values between those points also count since there is a line. Therefore, the domain of f is [-5, 6]. The brackets are used since the dots on -5 and 6 are shaded in meaning they also count for the domain.
