Find an equation of the line through the given points right the final answer in intercept form

Answer:

Step-by-step explanation:

x = length of screen

x-4 = width of screen

x² + (x-4)² = 20²

x² + (x²-8x+16) = 400

2x² - 8x - 384 =  0

x² - 4x - 192  = 0

use the quadratic formula to solve for x

x = [4 ± √(4²-4·1(-192))]/[2·1]

= [4 ± √784]/2

= 4 ±  28]/2

= 16, -12

-12 is an extraneous solution, so x = 16 inches.

:::::

Exponents need to be marked with a ^. For example, (x-4)² can be written (x-4)^2.

La pregunta está incompleta ya que no se da el costo de la colocación de baldosas por m².

Suponga que el costo de los mosaicos por m² = c

Respuesta:

39.06c

Explicación paso a paso:

El costo del embaldosado será:

El costo por m² * área total a embaldosar

Dado que :

La dimensión de la habitación a embaldosar es:

Longitud = 9,30 metros

Ancho = 4.20 metros

El área total de la habitación a embaldosar es = Largo * ancho

Área total de la habitación a embaldosar = 9,30 m * 4,20 m

Superficie total de la habitación a embaldosar = 39,06 m²

Si el costo del mosaico por m² = c

El costo de embaldosar la habitación será:

39,06 * c = 39,06c

Answer:

(-2,3)

Step-by-step explanation:

For the point to be 2/3 of the way; it means it divides AB into the ratio 2 to 1

Now, we can use the internal section formula to get the coordinates of this point

(x,y) = (nx1 + mx2)/(m + n), (ny1 + my2)/(m + n)

where (m,n) = (2,1)

(x1,y1) = (-4,-1)

(x2,y2) = (5,5)

(x,y) = (1(-4) + 2(-1)/(1+2), (1(-1)+2(5)/(1+2)

(x,y) = (-4-2)/3, (-1 + 10)/3

(x,y) = (-2,3)

67 adult  tickets were sold that day

Step-by-step explanation:

x= Number of adults that day, y=Number of children that day

ATQ, x+y=156 and 5.2*x+9*y=1065.8. Solving it, we will get x=89 and y=67

Answer:

Step-by-step explanation:

We first have to write the equation for the sequence, then finding the first five terms will be easy. Follow the formatting:

[tex]a_n=a_1+d(n-1)[/tex] and we are given enough info to fill in:

[tex]a_n=-35+4(n-1)[/tex] and

[tex]a_n=-35+4n-4[/tex] and

[tex]a_n=-39+4n[/tex] or in linear format:

[tex]a_n=4n-39[/tex] where n is the position of the number in the sequence. We already know the first term is -35.

The second term:

[tex]a_2=4(2)-39[/tex] so

[tex]a_2=8-39[/tex] and

[tex]a_2=-31[/tex]

The third term:

[tex]a_3=4(3)-39[/tex] and

[tex]a_3=12-39[/tex] so

[tex]a_3=-27[/tex] and we could go on like this forever, but the nice thing about this is when we know the difference all we have to do is add it to each number to get to the next number.

That means that the fourth term will be -27 + 4 which is -23.

The fifth term then will be -23 + 4 which is -19. You can check yourself by filling in a 5 for n in the equation and solving:

[tex]a_5=4(5)-39[/tex] and

[tex]a_5=20-39[/tex] so

[tex]a_5=-19[/tex]

Answer:

In diffuse reflection, reflected rays move in different directions.

Step-by-step explanation:

Reflection refers to the bouncing off of light from a surface. Reflection can be regular or diffuse.

Regular reflection occurs when light bounces off a well polished surface while diffuse reflection occurs when light bounces off a rough surface.

During diffuse reflection, light is reflected in different directions.

Answer:

SU

Step-by-step explanation:

The hypotenuse is opposite the right angle

The hypotenuse is US  or SU

We have to pick,

The segment which is hypotenuse,

Hypotenuse will be the opposite segment of the right angle.

Now it will be,

→ SU (or) US

Hence, SU is the hypotenuse.

Answer: Rs 275.40

Step-by-step explanation:

Since Sunayana borrowed a sum of Rs 25000 at 12 %p.a simple interest for 1 years 6 months, the total amount that she's expected to pay will be calculated thus:

First, well calculate the interest. This will be:

= PRT/100

= (25000 × 12 × 1.5 / 100)

= 4500

Total amount to be paid back will be:

= Rs 25000 + Rs 4500

= Rs 29500

Since she lent the money to Bishwant, the total amount that Bishwant will pay will be:

A = P(1 + r)^t

where,

A = Final Amount

P= Principal = 25000

r= Rate of interest =

t= Time = 3 cycles

Since it's compounded half yearly, then 1½ywars will be = 1½ × 2 = 3 cycles

The rate will be = 12%/2 = 6% yearly.

We'll then slot the values into the question and this will be:

A = P(1 + r)^t

A = 25000(1 + 0.06)³

A = 25000(1.06)³

A = 25000 × 1.191016

A = 29775.4

Therefore, Bishwant is expected to pay Rs 29775.4

Then the profit that Sunayana is expected to make will be:

= Rs 29775.4 - Rs 29500

= Rs 275.40

Answer:

a) In a coordinate plane, the horizontal axis is the x-axis, and the vertical axis is the y-axis.

So, a point (x, y) is at:

A horizontal distance of x units from the origin.

A vertical distance of y units from the origin.

So the point (3, -7) is at:

3 units at the right from the origin

7 units downwards (because is a -7) from the origin.

The graph of the point can be seen below:

Now we want to find a reflection across the x-axis.

b) For a general point (x, y), a reflection across the x-axis gives:

(x, -y)

So, if our point P is:

P (5, 1)

The reflection across the x-axis just changes the sign of the y-value, which gives:

(5, -1)

Then the correct option is point C:

(5, -1)

Answer:

bro i think its 0.75 . -2.25

Step-by-step explanation:

Answer:

Fourth option

Step-by-step explanation:

If you dont have a graphing calculator, we can solve this system using elimination. If we subtract the two linesr functions, we get

[tex](3x - 8y = 29) - (3x + y = - 2) = - 9y = 31[/tex]

So our new equation is

[tex] - 9y = 31[/tex]

[tex]y = - \frac{31}{9} [/tex]

Now since we know what y is, we plug this in back into the equation and solve for x.

[tex]3x - 8( \frac{ - 31}{9} ) = 29[/tex]

[tex]3x + \frac{248}{9} = 29[/tex]

[tex]3x = \frac{13}{9} [/tex]

[tex]x = \frac{13}{27} [/tex]

The answer choice that resembles this mostly is the fourth option.

Answer:

The length of [tex]b[/tex] is approximately 11.7.

Step-by-step explanation:

The sum of internal angles in triangles equals 180°, as we know the measures of angles B and C, we determine the measure of angle A by algebraic means:

[tex]A = 180^{\circ}-B-C[/tex] (1)

([tex]B = 22^{\circ}[/tex], [tex]C = 52^{\circ}[/tex])

[tex]A = 180^{\circ}-22^{\circ}-52^{\circ}[/tex]

[tex]A = 106^{\circ}[/tex]

The length of [tex]b[/tex] is found by the Law of Sine:

[tex]\frac{b}{\sin B} = \frac{a}{\sin A}[/tex]

[tex]b = a\cdot \left(\frac{\sin B}{\sin A} \right)[/tex]

([tex]a = 30[/tex], [tex]A = 106^{\circ}[/tex], [tex]B = 22^{\circ}[/tex])

[tex]b = 30\cdot \left(\frac{\sin 22^{\circ}}{\sin 106^{\circ}} \right)[/tex]

[tex]b \approx 11.7[/tex]

The length of [tex]b[/tex] is approximately 11.7.

Answer:

x = 1/5(k-14)

Step-by-step explanation:

5x + 14 = k

Subtract 14 from each side

5x+14-14 = k-14

5x = k-14

Divide by 5

5x/5 = 1/5(k-14)

x = 1/5(k-14)

Answer:

z^ 1/3

Step-by-step explanation:

sqrt( z / z^ 1/3)

We know a^b / a^c  =a^( b-c)

sqrt ( z^(1-1/3))

sqrt( z^ 2/3)

Rewriting sqrt as ^ 1/2

z^ (2/3) ^ 1/2

We know a^b^c = a^(b*c)

z^(2/3 * 1/2)

z^1/3

Answer:

? = 16

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

tan ? = opp side / adj

tan ? = 13 / 46

Taking the inverse tan of each side

tan ^ -1 ( tan ? ) = tan ^-1 ( 13/46)

? = 15.78075

To the nearest degree

? = 16

Answer:

Step-by-step explanation:

Now we have to find,

The answer to this problem.

Then use the property of exponents,

→ [tex] \sf a^cb^c = (ab)^c[/tex]

Let's find the solution,

→ 9b²c²

→ 3²b²c²

→ (3bc)²

Hence, (3bc)² is the answer.

It is 6x -23y. You cannot factor using GCF any further.

Step-by-step explanation:

Reflection over y axis rule

(x,y) --------> (-x,y)

Rule explained:

Simply change the sign of the x value and keep the y value as it it

Coordinates of A (-4,0)

Apply reflection over y axis rule

(-4,0) -----> (4,0)

Next we want to apply a translation with the rule ( x - 5 , y + 2 )

Explanation of rule:

Simply subtract 5 from the x value and add 2 to the y value

Current coordinates of A (4,0)

Apply translation rule

(4,0) -------> ( 4 - 5 , 0 + 2 ) --------> (-1 , 2 )

The y value of coordinate A would be 2 after all of the transformations
