Kate has an interior decorating business. She charges a base fee of $25 for each visit and $40 per hour for her labor. 1) Write a function rule to represent this situation for, C, the total cost and h number of hours. 2) Identify the domain and range for the situation. 3) Explain if the situation is discrete or continuous. (if there is no explanation, there will be no credit given) PLEASE I NEED FAST ILL GIVE BRAINLIEST

Answers

Answer 1

Answer:

1) C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) Continuous

Step-by-step explanation:

1) The given parameters are;

The base fee charged = $25

The amount charged for labor = $40/hour

The total cost for h number of hours is C = $25 + $40 × h

2) The domain for the ≠unction is 0 ≤ h ≤ ∞

The range for the function is 25 ≤ C ≤ ∞

3) The situation is continuous because the different input values of h can be infinite (from o to infinity)

Using the elimination method, we can solve this system of equations. You must find a common multiple of both equation for either x or y. I chose to multiply equation 2 by (-2) so that the x would be eliminated, allowing us to solve for y.

Quadrilateral ABCD undergoes a reflection across the x-axis to form quadrilateral a b c d the coordinates of a r the reflected quadrilateral a b c d is then translated three units to the right and third and two units up to form quadrilateral a quotation b quotation quotation see quotation

Answers

Solution :

From the figure,

The coordinates of --

A = (-5,-3)

B = (-6,-1)

C = (-3,-1)  

D = (-2,-3)

When it undergoes reflection about x-axis, we have the coordinates of the quadrilateral as

A' = (-5,+3)

B' = (-6,+1)

C' = (-3,+1)

D' = (-2,+3)

Now A'B'C'D' is translated 3 units to right, so the coordinates will be --

A" = (-2,3)

B" = (-3,1)

C" = (0,1)

D" = (1,3)

When the quadrilateral moves third and two units up, we get

A"' = (3,3)

B"' = (2,1)

C"' = (5,1)

D"' = (6,3)

There were 43 children at the playground. Now there are 27 children at the playground. How many children left the playground? Ben says that 13 children left the playground. He thinks that 43 – 30 is easier to subtract than 43 – 27. He subtracts 43 – 30 and gets 13. Why is Ben's reasoning not correct?

Answers

Ben is incorrect because Ben did not answer the question according to the available information. The fact that subtracting 43 from 30 is easier for Ben does not mean it is the correct answer.

How much of each metal is needed to make 3.6 kg of this alloy?

Answers

Answer:

0.4kg, 1.4kg and 1.8kg

Step-by-step explanation:

Given parameters:

         Mass of alloy = 3.6kg

         Ratio of elements in the alloy = 2:7:9

Unknown:

Mass of each element in the alloy = ?

Solution:

To find the mass of each element in the alloy, first find the sum of the ratio;

              2+7+9 = 18

Mass of nickel  = [tex]\frac{2}{18}[/tex] x 3.6 = 0.4kg

Mass of zinc = [tex]\frac{7}{18}[/tex] x 3.6 = 1.4kg

Mass of copper = [tex]\frac{9}{18}[/tex] x 3.6 = 1.8kg

The mass of each metal is 0.4kg, 1.4kg and 1.8kg

Answer:

Nickle=0.4

Zinc=1.4

Copper=1.8

add ( half the coefficient of the x- term )² to x² + 7x

x² + 2([tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] , thus

her savings account. If her paycheck deposits are the only transactions, which of the

following equations could be used to find y, the amount in her savings account based

on x, the number of times she is paid?

A y = 2,835 - 945x

B 2,835y = 945x

C y = 945x + 2,835

D y = 2,835x + 945

Answers

Answer:

C. y = 945x + 2,835

Step-by-step explanation:

Each pay period 945 dollars is deposited so that's the slope, which x stands for each pay period. She already started with 2,835 in her savings account so that is the y-intercept.

Slope: 945x

Y- intercept: 2,835

Therefore,

equation: y = 945x + 2,835
