Answer:

The equation that represents the total cost in dollars is C = 100p + 300

Step-by-step explanation:

The form of the linear equation is y = m x + b, where

m is the slope ⇒ rate of change

b is the y-intercept ⇒ fixed amount

∵ Avery must pay a daily fixed cost to rent the building and equipment

∴ There is a fixed amount b

∵ She pays a cost per phone produced for materials and labor

∴ There is a rate m

∵ C represents the total cost of producing p phones in dollars

→ Form the linear equation for the situation

∴ The equation is C = m p + b

∵ The labor and materials cost $100 for each phone

∴ m = 100

→ Substitute it in the equation above

∴ C = 100p + b

∵ The cost of producing 3 phones in a day would be $600

∴ p = 3 and C = 600

→ Substitute them in the equation above to find b

∵ 600 = 100(3) + b

∴ 600 = 300 + b

→ Subtract 300 from both sides to find b

∵ 600 - 300 = 300 - 300 + b

∴ 300 = b

→ Substitute it in the equation

∴ C = 100p + 300

∴ The equation that represents the total cost in dollars is C = 100p + 300

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the school in ho

Ede4ka [16]

Solution:

we are given that

A school director Must randomly select 6 teachers to participate in a training session there are 30 teachers at the schoo. The order of selection does not matter.

As we know

6 teacheras can be selected out of 30 teacher in ${30}_C_6$ ways.

${30}_C_6=\frac{30!}{6!24!}\\
\\ {30}_C_6=\frac{25*26*27*28*29*30}{1*2*3*4*5*6}\\
\\ {30}_C_6=593775$

Hence the required number of ways is 593775.

Prove that a triangle with the sides a - 1 cm to root under a

vivado [14]

Question is Incomplete, Complete question is given below.

Prove that a triangle with the sides (a − 1) cm, 2√a cm and (a + 1) cm is a right angled triangle.

Answer:

∆ABC is right angled triangle with right angle at B.

Step-by-step explanation:

Given : Triangle having sides (a - 1) cm, 2√a and (a + 1) cm.

We need to prove that triangle is the right angled triangle.

Let the triangle be denoted by Δ ABC with side as;

AB = (a - 1) cm

BC = (2√ a) cm

CA = (a + 1) cm

Hence,

${AB}^2 = (a -1)^2$

Now We know that

$(a- b)^2 = a^2+b^2 - 2ab$

So;

${AB}^2= a^2 + 1^2 -2\times a \times1$

${AB}^2 = a^2 + 1 -2a$

Now;

${BC}^2 = (2\sqrt{a})^2= 4a$

Also;

${CA}^2 = (a + 1)^2$

Now We know that

$(a+ b)^2 = a^2+b^2 + 2ab$

${CA}^2= a^2 + 1^2 +2\times a \times1$

${CA}^2 = a^2 + 1 +2a$

${CA}^2 = AB^2 + BC^2$

[By Pythagoras theorem]

$a^2 + 1 +2a = a^2 + 1 - 2a + 4a\\\\a^2 + 1 +2a= a^2 + 1 +2a$

Hence, ${CA}^2 = AB^2 + BC^2$

Now In right angled triangle the sum of square of two sides of triangle is equal to square of the third side.

This proves that ∆ABC is right angled triangle with right angle at B.
