Answer:

B. [tex] y = kx [/tex] , where k is the constant of proportionality.

Step-by-step explanation:

Given that quantity x and y is directly proportional to each other, which means as one variable increases, the other increases as well. Thus, the constant of proportionality, which is often denotes with the alphabet k, can be represented by the following equation:

[tex] y = kx [/tex] , where, k is the constant of proportionality.

Constant of proportionality, k, is gotten when you divide the value of y by the value of x.

Answer:

Step-by-step explanation:

To find the mass of an object given it's acceleration and the force acting on it we use the formula

[tex]mass = \frac{force}{acceleration} \\ [/tex]

From the question

force = 45 N

acceleration = 39 m/s²

We have

[tex]force = \frac{45}{39} = \frac{15}{13} \\ = 1.153846...[/tex]

We have the final answer as

The equivalent expression of 25 - 64 are "a), b) and c)"

The given expression is:

25 - 64

To find, the equivalent expressions are:

a) 25 + 40x - 40x - 64

=  25 - 64, is the equivalent expression.

b) 25 + 13x - 13x - 64

=  25 - 64, is the equivalent expression.

c) (5 + 8)(5 - 8)

Using the algebraic identity,

(a + b)(a - b) =

=

=  25 - 64, is the equivalent expression.

d) ( + 13)( - 13)

Using the algebraic identity,

(a + b)(a - b) =

=

=   - 169, is not a equivalent expression.

e)

Using the algebraic identity,

,  is not a equivalent expression.

∴ The equivalent expression of 25 - 64 are "a), b) and c)".

Answer: option A, B, C are equivalent to [tex]25x^4-64[/tex].

We check each option by simplifying:

A) [tex]25x^4 + 40x - 40x - 64 = 25x^4-64[/tex].

B) [tex]25x^4 + 13x - 13x - 64 = 25x^4-64[/tex]

C) [tex](5x^2 + 8)(5x^2 - 8)=(5x^2)^2-8^2=25x^4-64[/tex]

D) [tex](x^2 + 13)(x^2 - 13)=(x^2)^2-13^2=x^4-169[/tex]

E) [tex](5x^2 - 8)^2=(5x^2)^2-2(5x^2)(8)+8^2=25x^4-80x^2+64[/tex].

So option A, B, C are equivalent to [tex]25x^4-64[/tex].

Answer:

25 is the 14th term.

Step-by-step explanation:

The nth term of a sequence is given by the following explicit rule:

f(n) =5.5n - 52

We need to find the position n of the term of value 25. In other words, find n in the equation:

5.5n - 52=25

Adding 52:

5.5n =25+52=77

Solving:

n=77/5.5

n=14

25 is the 14th term.

Answer:

He should use 1/2 of a teaspoon of pepper.

Step-by-step explanation:

From the question, the soup recipe requires 1/4 of a teaspoon of pepper for every 1/2 of a teaspoon of dried basil.

Now, to determine how much pepper Terrell should use if he uses 1 teaspoon of dried basil for the huge pot of soup,

Let the quantity be x

If 1/4 of a teaspoon of pepper requires 1/2 of a teaspoon of dried basil,

then, x teaspoon of pepper will require 1 teaspoon of dried basil

x = (1/4 × 1) ÷ (1/2)

x = 1/4 ÷ 1/2

x = 1/4 × 2/1

x = 2/4

x = 1/2

∴ 1/2 of a teaspoon of pepper is required for 1 teaspoon of dried basil.

Hence, he should use 1/2 of a teaspoon of pepper.

Answer:

Step-by-step explanation:

let sale be x

and his salary be y

y=300+0.4x----------1 the old equation

y=450+0.2x----------2 the new equation

for his salary to be the same

equation 1 and 2 must be equal hence

300+0.4x=450+0.2x

solving for x we have

300-450+0.4x-0.2x=0

-150+0.2x=0

0.2x=150

x=150/0.2

x=$750

____________________________

Reminder:

[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]

So we need to just Multiply above equations like this :

[tex]x + y = 70[/tex]

[tex]x - y = 40[/tex]

[tex](x + y)(x - y) = 70 \times 40[/tex]

[tex] {x}^{2} - {y}^{2} = 2800 [/tex]

Answer:

105

Step-by-step explanation:

since its  a straight line it would add up to 180 degrees so 52 + 23 + 75 and you need 180 so 180-75 which gives 105 which is the missing angle

Answer:

105 degrees

Step-by-step explanation:

First add the angles that you already know, 52 + 23 = 75, then since we know that the whole thing is a straight angle (180 degrees) 180-75 = 105 degrees.

Hope this helped!

Answer:

Answer:

RHS

Step-by-step explanation:

It is given that XY is the perpendicular bisector of WZ. This means that it forms 90-degree angles at Y. (angle XYZ and angle XYW are 90 degrees). (R)

Since there is a right angle at Y, XZ and XW are the hypotenuses. (H)

There is a common line between triangle XYZ and XYW and that is XY. (S)

Therefore you can prove ΔXYZ ≅ΔXYW because of RHS
