8th fall- 203 9th fall-95

Step-by-step explanation:

the 9th total is 500

8th fall is 203

9th fall is 95

The maximum number of tourists in the third week will be maximum in the numberville city.The solution of f(x)=h(x) will be x(5,2).

The equation is actually a relationship between the numbers and the variables.

To calculate the number of the tourists in the third week we will put the value 3 in every function:

[tex]f(x)=x^2+5x+10=(3)^2+(3\times 3)+10=29\\\\\\g(x)=3^x=3^3=27\\\\\\h(x)=10x=10\times 3=30[/tex]

So we can see that the function third h(x) numberville city is having a maximum number of tourists.

The solution of f(x)=h(x) will be calculated as:

[tex]x^2-3x+10=10x\\\\\\x^2-7x+10=0\\\\\\x^2-5x-2x+10=0\\\\\\x(x-5)-2(x-5)=0\\\\\\x=5,2[/tex]

Hence the solution of f(x)=h(x) will be x(5,2).

Answer
2 (9 x + 4 y)

Hope this helps :)

Answer:

x = 2

Step-by-step explanation:

3x + 5y = -9 ___(1)

y = 2x - 7

Substituting y's value in (1) ..

3x + 5( 2x - 7) = -9

3x + 10x -35 = -9

13x = -9 + 35

13x = 26

x = 26/13

x = 2

Answer:

4, -4

Step-by-step explanation:

I think the first equation is ax + 3y = 2, not az + 3y = 2.

ax + 3y = 2

4x + 5y = 6

To use elimination, you need the coefficients of a to either add to zero, or to have a difference of zero if you subtract them.

a + 4 = 0

a = -4

a - 4 = 0

a = 4

Answer: a must be 4 or -4.

Answer:

-4 and 4

Step-by-step explanation:

Given linear system:

[tex]ax+3y=2[/tex]

[tex]4x+5y=6[/tex]

In order to solve the given linear system by elimination without multiplying first, [tex]a[/tex] must be either -4 or 4.  That way, when you add or subtract the equations, the variable [tex]x[/tex] will be eliminated.

when [tex]a = -4[/tex]:

Answer:

Has infinite solutions

Explanation:

-x + 5y = -3..... eq1

2x - 10y = 6 .... eq2

===============

make x the subject in equation 1

-x + 5y = -3

-x = -3 - 5y

x = 5y + 3

========= insert this in equation 2

2(5y + 3) - 10y = 6

10y + 6 -10y = 6

6 = 6

So, Has infinite solutions as L.H.S = R.H.S

Step-by-step explanation:

2 • [(6 + 1)2 + 1]

First The Brackets :

[(6 + 1)

->>> 6 + 1

= 7

But there's a bracket around 6 + 1 so now we multiply

-->>> [(7)2 + 1]

->>> 7 x 2

= 14

So now we add :

= 15

And now we multiply:

Answer:

D. 5(x + 3)(x - 3)

Step-by-step explanation:

a² - b² = (a + b) (a - b)

5(x + 3)(x - 3)

5(x² - 9)

(5x² - 45)

5x² - 45

Option D is correct, the factored form of the expression  5x² - 45 is 5(x+3)(x - 3)

An expression is combination of variables, numbers and operators.

The given expression is 5x² - 45

Five times of x square minus forty five

x is the variable and minus is the operator

Let us take 5 common from the expression to find the factor form

5(x² - 9)

5(x² - 3²)

Now we know that a² - b²  = (a+b)(a-b)

5(x+3)(x-3)

Hence, the factored form of the expression  5x² - 45 is 5(x+3)(x - 3)

Answer:

2(30) + 2(27) + 2(90) = 294

Answer:4/10 =2/5

Step-by-step explanation:

you subtract the numerator but the denominator stays the same. I then found a number that could be divided into both numbers and got 2/5.

Answer:

Question 1

Cost per 10,000 Popsicle sticks = $725.20

⇒ Single Popsicle stick = 725.20 ÷ 10000 = $0.07 (nearest cent)

Question 2

Cost per 1,000 motherboards = $8,730

⇒ Cost of Single motherboard = 8730 ÷ 1000 = $8.73

Cost per 10 motherboards = $100

⇒ Cost of Single motherboard = 100 ÷ 10 = $10

Difference = 10 - 8.73 = $1.27

Question 3

Create a table with the cost per 1 unit:

[tex]\begin{array}{| c | c | c | c |}\cline{1-4} \sf PART & \sf COST\:PER\:1\:of\:10 & \sf COST\:PER\:1\:of\:1000 & \sf COST\:PER\:1\:of\:10000\\\cline{1-4} \sf Motherboard & \$10.00 & \$8.73 & \$7.04 \\\cline{1-4} \sf Processor & \$5.00 & \$1.25 & \$0.63 \\\cline{1-4} \sf Popsicle & \$0.10 & \$0.09 & \$0.07 \\\cline{1-4} \sf Motor & \$4.50 & \$0.18 & \$0.04 \\\cline{1-4} \sf Sensor & \$6.30 & \$4.54 & \$3.18 \\\cline{1-4} \sf Small\:gear & \$1.00 & \$0.80 & \$0.70 \\\cline{1-4} \end{array}[/tex]

From inspection of the table, the Motor saves the most money per unit when 10,000 is bought, since the difference between the cost of 1 unit is the greatest for this part.

Question 4

Cost of 1100 motherboards

= cost of 1000 +  cost of 10 x 10

= 8730 + 100 x 10

= 8730 + 1000

= $9,730

Question 5

Cost of 12050 sensors

= cost of 10000 + cost of 1000 x 2 + cost of 10 x 5

= 31752 + 4536 x 2 + 63 x 5

= 31752 + 9072 + 315

= $41,139

Answer:

Step-by-step explanation:

The explanation of the problem is  shown in the attached figure.

AS shown in the  graph:

At t = 0 the speed = 4 miles/h then decrease to the speed = 2 miles/h during the first 3 seconds then increased to 5 miles/h during the next 2 seconds, then it became constant at 5 miles/h for the last 5 seconds.

So, the correct option is:

A. The speed of the car decreases from 4 mi/h to 2 mi/h in the first 3 seconds, increases to 5 mi/h in the next 2 seconds, and then remains at 5 mi/h for the last 5 seconds.

Tan65°=h/75m
