how do i solve 7x^{2} +11y^{2} =40

Answers

Answer 1

Answer:

Step-by-step explanation:

There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.

[tex]7x^2+11y^2=40\\ \\ 11y^2=40-7x^2\\ \\ y^2=\frac{40-7x^2}{11}\\ \\ y=\sqrt{\frac{40-7x^2}{11}}[/tex]

Answers

Answer:

y = -1

Step-by-step explanation:

Given x = 30 , y = 14 -0.5x

Find y

let (x = 30) fill in y

y = 14 - 0.5(30)

y = 14 - 15

Thus , y = -1

Point A and Point B are 5 units apart.

h
What are the possible coordinates for Point B?

Answers

Answer:

[tex]\boxed{\textsf{ The possible values of y is \textbf{ 3 or -3 }.}}[/tex]

Step-by-step explanation:

Here Point A and B are 5 units apart . The coordinates of A are (-1,2) and B is (-1,y) .We need to find the possible coordinates of y . So let's use Distance Formula :-

[tex]\rule{200}2[/tex]

★ Distance Formula :-

If we need to find the distance between two points say , [tex]\sf ( x_1,y_1 ) \:\:\:\: \& \:\:\:\: ( x_2,y_2) [/tex] , then we can find out the distance as ,

[tex]\boxed{\boxed{ \sf Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2 } }}[/tex]

[tex]\rule{200}2[/tex]

Put on the respective values ,

[tex]\sf\implies Distance =\sqrt{ ( x_2-x_1)^2+(y_2-y_1)^2 } \\\\\sf\implies Distance = \sqrt{ (-1+1)^2+(2-y)^2}\\\\\sf\implies Distance =\sqrt{ (2-y)^2 } \\\\\sf\implies 5^2 = (2-y)^2 \\\\\sf\implies 5 = \pm (2-y) \\\\\sf\implies 5 = (2-y) \qquad or \qquad 5= -(2-y)\\\\\sf\implies y = 2-5 \qquad or \qquad y = 5-2 \\\\\sf\implies\boxed{\pink{\frak{ y = \pm 3 }}}[/tex]

May someone please help me out with this problem? May you also explain it?

Answer:

Step-by-step explanation:

Given function is,

f(x) = [tex]\sqrt{x}[/tex]

If the given function is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] Or 1.5,

Transformed function will be,

h(x) = [tex]\frac{3}{2}[f(x)][/tex]

h(x) = [tex]\frac{3}{2}(\sqrt{x})[/tex]

Further function 'h' is shifted 1 units upwards,

g(x) = h(x) + 1

g(x) = [tex]\frac{3}{2}(\sqrt{x} )+1[/tex]

Domain of the function → x ≥ 0 Or [0, ∞)

Range of the function → y ≥ 1 Or [1, ∞)

Transformations done → Parent function f(x) is vertically stretched by a scale factor of [tex]\frac{3}{2}[/tex] then shifted 1 unit upward.

Write the ratio of all people to people who​ don't ride the tram in three ways. Write the ratio of people who ride the tram to all people in three ways.

Answers

Answer:

= 3 to 7

= 3 : 7

= 3/7

Step-by-step explanation:

Number of people who ride the tram = 3

Number of people who does not ride the tram = 4

Total people = 3 + 4 = 7

Ratio of people who ride the tram to all people in three ways.

= 3 to 7

= 3 : 7

= 3/7

Ratio of all people to people who​ don't ride the tram in three ways.

= 7 to 4

= 7 : 4

= 7/4

Ratio of people who ride the tram to all people in three ways.

= 3 to 7

= 3 : 7

= 3/7

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una. ¿Cuánto pagó por todo?

Answers

Answer:

Costo Total= $38,680

Step-by-step explanation:

Dada la siguiente información:

Un comerciante compra 16 máquinas de coser a S/.408 cada una: 27 equipos de sonido a S/. 732 cada uno y 19 lavadoras a S/. 652 cada una.

Para calcular el costo total, debemos usar la siguiente formula:

Costo Total= costo unitario * cantidad adquirida

Costo Total= 408*16 + 732*27 + 652*19

Costo Total= $38,680

The total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

What is the cost price?

The cost price refers to the original price of the items, it is the total amount of money that costs a manufacturer to provide a given product.

The unit cost of sewing machines = 408

The unit cost of a sound system = 732

The unit cost of a washing machine = 652

Total cost = 408 × 16 + 732 × 27 + 652 × 19

                = 6528 + 19764 + 12388

                = $38,680

Therefore, the total amount of everything including sewing machines, sound systems, and washing machine is $38,680.

The heights of a triangle ABC meet at a point K.AB=CK.Find the angle of C.​

Answers

Answer:

45°

Step-by-step explanation:

AD⊥BC, BE⊥AC, CF⊥AB           AB = CK

∠1 + ∠2 = 90°        ∠5 + ∠2 = 90°              ∴ ∠1 = ∠5

∠5 + ∠4 = 90°                                            ∴ ∠4 = ∠2

AB = CK

ΔABD ≅ ΔCKD  (ASA)

AD = CD       ∴ΔADC is an isosceles triangle

∠C = ∠CAD = 45°       (∠C + ∠CAD = 90°)
