Answer:

$9,600 is what he'll earn in all but the interest that he will earn is $5600

Step-by-step explanation:

To find out the interest earned in all you multiply 4000 times .4 times 6 which is 9600 so if you want to figure out the interest paid it is 9600 - 4000 which is 5600

Answer:

Equation 1: x-3y+5=0

Equation 2: 3x+y-1=0

Step-by-step explanation:

Equation 1: x+3y=-5

                  x+3y+5=-5+5

                  x=3y+5=0

Equation 2: 9x+3y-3=0

                   3x+y-1=0

Answer:

The answer is "$150".

Step-by-step explanation:

Please find the complete question in the attached file.

In this question first, we include the quantity of food that these cats eat daily.  

[tex]\to \frac{3}{4}= 0.75\\\\\to \frac{1}{2}= 0.5 \\\\ \to 0.75+ 0.5=1.25[/tex]

They are now able to eat the total of meat we consume on a daily basis, that the food we still eat is 1,25 cans each day, and we must have the full 3 cans.  

[tex]\to 1.25 \times 2=2.50[/tex]

2.5 cans and they eat 2.5 cans every 2 years with every other day so we'll have to purchase more meat. So let's go to buy some at our favourite place. 2.5 cans one another day to allow us to give the Bobo leftover .5 a can and open the new Rover can.  

We also left this meal 1.25 cans, so that we can give it to them tomorrow. The feed time would not allow them to purchase food as we have the right quantity of food left. But we went for 6 cans in 4 days. Let's figure out how we're going to divide 60 by 4  =15

So we have 15 times 6 now, because that will provide us with the answer   [tex]\to 15 \times 6=90[/tex]

We finally find out just how much we pay by 90 cans in 60 days so we will find out what it costs us.  

That's the number of cans we get from each purchase and we will divide 90 by 3.  

[tex]\to \frac{90}{3}=30[/tex]

They are going to multiply 30 times 5 now, since that is the sum of money to buy.

[tex]\to 30 \times 5=150[/tex]

Answer:

83.07

Step-by-step explanation:

If you multiple the original price $78 times the sale tax in decimal form 0.065 you get 5.07, $78 + $5.07 = 83.07.

Step-by-step explanation:

Step 1:  List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2:  Find the values for the given numbers

sin(J) = opposite/hypotenuse = 24/25

tan(J) = opposite/adjacent = 24/7

sin(K) = opposite/hypotenuse = 7/25

tan(K) = opposite/adjacent = 7/24

Step 3:  Check if the answers match

24/25 = 24/25 So it is TRUE

24/7 != 7/25 So it is FALSE

7/25 != 24/25 So it is FALSE

7/24 = 7/24 So it is TRUE

Answer: TRUE, FALSE, FALSE, TRUE

Answer:

A. 14

Step-by-step explanation:

A circle has 360 degrees. Lose a turn region is half, so 180.   360-180=180

If the answer is A, move two spaces region would be 56 degrees because 14*4=56

56+14=70

Move one space is 2 times move two spaces so 56*2=112

112+70=182

182+180=362

182 is the closest you can get to 180 without having a decimal.

Answer:

These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°:

Notice that together they make a straight angle.

supplementary angles 60 and 120

But the angles don't have to be together.

These two are supplementary because

60° + 120° = 180°

Answer:

A = 3

2A5A0A2 = 2353032

Step-by-step explanation:

Given:

2A5A0A2 is divisible by 9

2A5A0A2 can be divisible by 99 if the sum of the digits can be divided by 9

Digits A is between 0 to 9

2 + A + 5 + A + 0 + A + 2 = 9x

Where,

x = multiples of 9

9 + 3A = 9x

Make A the subject

A = (9x - 9) / 3

When x = 0

A = {9(0) - 9} / 3

= (0 - 9) /3

= -9/3

= -3

When x = 1

A = (9x - 9) / 3

= 9(1) - 9 /3

= 9-9/3

=0/3

A = 0

When x = 2

A = (9x - 9) / 3

= 9(2) -9 / 3

= 18-9/3

= 9/3

A = 3

When x = 3

A = (9x - 9) / 3

= 9(3) - 9 / 3

=27 - 9 /3

= 18/3

A = 6

When x = 4

A = (9x - 9) / 3

= 9(4) -9 /3

= 36-9/3

= 27/3

= 9

Recall, Digits A is between 0 to 9

Substituting A = 0

2050002 ÷ 99

= 20707.09

Substituting A = 3

2A5A0A2

2353032 ÷ 99

= 23,768

Substituting A = 6

2A5A0A2

2656062 ÷ 99

= 26,838.91

Substituting A = 9

2A5A0A2

2959092 ÷ 99

= 29,889.82

Therefore, the only A digit that will not give a decimal number when divided by 9 is 3

A = 3

Missing Part of the question:

a) Assume you wish to determine the maximum and minimum temperatures you would experience. the domain to study for the function H(x) would be?

b)The is one critical number for the function on the domain in part a and it is?

c) The maximum temperature you would experience is ?

d) The minimum temperature you would experience is ?

Answer:

a. Domain : [tex]4 \leq x \leq 41[/tex]

b. Critical point: [tex]x = 12.33[/tex]

c. The maximum is 115.09

d. The minimum is 100.62

Step-by-step explanation:

Given

[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Solving (a): The domain of H(x)

From the question, we understand that the distance between the two stores is 45ft

Let the first stove be at point A (0 ft) and

the second stove be at point B (45ft)

Since you move back and forth within 4ft from either stoves, then

Your maximum distance at A is (0 + 4) ft = 4ft

Your minimum distance at B is (45 - 4) ft = 41ft

Hence, the domain is: [tex]4 \leq x \leq 41[/tex]

Solving (b): Critical Value

First, we have to differentiate H(x) w.r.t x

[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Differentiate

[tex]H'(x) = 0 -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

[tex]H'(x) = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

Equate H'(x) to 0

[tex]0 = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

Rewrite as:

[tex]\frac{120}{x^3} = \frac{480}{(45- x)^3}[/tex]

Cross Multiply

[tex]480 * x^3 = 120 * (45 -x)^3[/tex]

[tex]480 * x^3 = 120 * (45 -x)*(45 -x) * (45 -x)[/tex]

[tex]480 * x^3 = 120 * (2025 -90x +x^2) * (45 -x)[/tex]

[tex]480 * x^3 = 120 * (91125 -4050x +45x^2 -2025x - 90x^2 - x^3)[/tex]

[tex]480 * x^3 = 120 * (91125 -4050x -2025x+45x^2 - 90x^2 - x^3)[/tex]

[tex]480 * x^3 = 120 * (91125 -6075x-45x^2 - x^3)[/tex]

Divide both sides by 120

[tex]4x^3 =91125 -6075x-45x^2 - x^3[/tex]

[tex]4x^3 +x^3-91125 +6075x+45x^2= 0[/tex]

[tex]5x^3-91125 +6075x+45x^2= 0[/tex]

[tex]5x^3+45x^2 +6075x-91125= 0[/tex]

Divide through by 5

[tex]x^3+9x^2 +1215x-18225= 0[/tex]

Solving for x, we have that

[tex]x\approx \:12.33067[/tex]

[tex]x = 12.33[/tex]

Hence, the critical point is 12.33

Solving (x): Maximum temperature

Here, we simply substitute the endpoints of the domain in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Let x = 4

[tex]H(4) = 100 + \frac{60}{4^2} + \frac{240}{(45 - 4)^2}[/tex]

[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{(41)^2}[/tex]

[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{1681}[/tex]

[tex]H(4) = 100 + 3.75+ 0.14277215942[/tex]

[tex]H(4) = 103.892772159[/tex]

[tex]H(4) = 103.89[/tex] --- approximated

Let x = 41

[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{(45 - 41)^2}[/tex]

[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{4^2}[/tex]

[tex]H(41) = 100 + \frac{60}{1681} + \frac{240}{16}[/tex]

[tex]H(41) = 100 + 0.03569303985 + 15[/tex]

[tex]H(41) = 115.03569304[/tex]

[tex]H(41) = 115.04[/tex] ---- approximated

Compare both values: The maximum is 115.09

Solving (d): The minimum temperature

In (b), we have that:

[tex]x = 12.33[/tex] --- critical point

The minimum occurs at this point

Substitute 12.33 for x in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{(45 - 12.33)^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{32.67^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{152.0289} + \frac{240}{1067.3289}[/tex]

[tex]H(12.33) = 100 + 0.39466180443 + 0.22486039682[/tex]

[tex]H(12.33) = 100.619522201[/tex]

[tex]H(12.33) = 100.62[/tex] --- approximated

Hence, the minimum is 100.62

Answer:

Step-by-step explanation:

We can see the lines are parallel

The function f(x) has y-intercept of 2 at point (2, 0) and the function g(x) has y-intercept of -3 at point of (-3, 0)

If f(x) = mx + 2, then g(x) = mx - 3

The value of k is the difference of y-intercepts as slopes are same due to lines being parallel:

So the answer is k = -5
