As one of the grade 9 top performing students competing for the “Boy Scout of the Year” award, you are assigned by your scoutmaster to design a camping site for the coming Boy Scout in-door camping. You have to maximize the area at which the 20 scouts can assemble their own tents. The tents should be equally spaced and must be situated at the same distance of 20 m from the tent of the scout master, which is located at the center of the scouts. The angle at which the tents are positioned from the scoutmaster should be approximately the same. Would you know how far apart the tents of the scouts are from each other?

i beliebe 3×=0

ao the answer should be x/0

Answer:

-3x

Step-by-step explanation:

The order of where the terms are placed definitely matter for subtraction. 5x-2x is 3x, but because the smaller number is first, we've gone into the negatives. Think of it like this:

2x - 5x

-2x   -2x

__    __

0      -3x

Because we still have the - in front of the 3, it is a negative 3.

Answer:

y=10°

Step-by-step explanation:

Here,

→(3x+18)°=(5x-4)°

→18°+4°=5x-3x

→22°=2x

→x=11°

Also,

3(4y+3)°+5x-4°=180°[The sum of the linear pair is 180°]

12y+9°+5x-4°=180°

12y+5°+5×11°=180°

12y+5°+55°=180°

12y=180°-60°

12y=120°

y=120°/12

y=10°

Opposite angles are equal

Now

linear pairs are supplementary

When starting a problem, almost every single problem needs to be understood by the person answering so they can see what needs to be done.  In this example, we are given an expression and told to solve the equation which means that we need to solve for the unknown, in this case x.

Now that we know what we must do, we can start to solve the problem. Looking at the problem we can see that the step that we must take is to distribute 3 into the parenthesis.

Distribute

Now that we distributed the values inside of the parenthesis we can move onto the next step which is to help isolate x.  What we should do is subtract 6 from both sides which will help leave x with its coefficient alone.

Subtract 6 from both sides

The next step that we should take to help solve for the unknown is to subtract 3x from both sides.

Subtract 3x from both sides

The final step that we must take to help isolate the unknown would be to divide both sides by 3.  This would remove the coefficient from x and we would get -21 divided by 3.

Divide both sides by 3

Therefore, after simplifying the expression that was given to solve for the unknown we were able to determine that the option that would best match the solution is option A, x = -7.

Answer:

a) x = -7

Step-by-step explanation:

Given: 3(2x + 2) = 3x - 15

1. Distribute:

3(2x) + 3(2) = 3x - 15

⟹ 6x + 6 = 3x - 15

2. Subtract 3x from both sides:

6x - 3x + 6 = 3x - 3x - 15

⟹ 3x + 6 = -15

3. Subtract 6 from both sides:

3x + 6 - 6 = -15 - 6

⟹ 3x = -21

4. Divide both sides by 3:

3x ÷ 3 = -21 ÷ 3

⟹ x = -7

5. Check your work:

3(2x + 2) = 3x - 15

3(2(-7) + 2) = 3(-7) - 15

3(-14 + 2) = -21 - 15

3(-12) = -21 - 15

⟹ -36 = -36 ✔

Given function:

[tex]f(x)=2(3)^x[/tex]

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

[tex]\begin{aligned}\textsf{Average rate of change - Section A} & =\dfrac{f(1)-f(0)}{1-0}\\\\& =\dfrac{2(3)^1-2(3)^0}{1-0}\\\\& =\dfrac{6-2}{1}\\\\& =4 \end{aligned}[/tex]

[tex]\begin{aligned}\textsf{Average rate of change - Section B} & =\dfrac{f(3)-f(2)}{3-2}\\\\& =\dfrac{2(3)^3-2(3)^2}{3-2}\\\\& =\dfrac{54-18}{1}\\\\& =36 \end{aligned}[/tex]

[tex]\dfrac{\textsf{Average rate of change of Section B}}{\textsf{Average rate of change of Section A}}=\dfrac{36}{4}=9[/tex]

Therefore, the average rate of change of Section B is 9 times greater than Section A.

The function is an exponential function (with 3 as the growth factor) so the rate of change increases over time.

Answer:

-0.38

Step-by-step explanation:

Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

Applying implicit differentiation, the rate of change is given by:

[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]

In this problem, we have that:

[tex]\frac{dV}{dt} = 500, r = 70[/tex]

Hence the rate of change of the radius is given as follows:

[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]

[tex]19600\pi\frac{dr}{dt} = 500[/tex]

[tex]\frac{dr}{dt} = \frac{500}{19600\pi}[/tex]

[tex]\frac{dr}{dt} = 0.0081[/tex]

The radius is increasing at a rate of 0.0081 cm per minute.

Answer: 4 2/3 or 14/3 if wanting a improper fraction.

Answer:

Tabled Function

Step-by-step explanation:

To determine which function is increasing the fastest over the interval [-5, 3], we need to calculate and compare each function's average rate of change over the given interval.

The average rate of change of function f(x) over the interval a ≤ x ≤ b is given by:

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given interval:  -5 ≤ x ≤ 3

Therefore, a = -5  and  b = 3

[tex]f(3)=7[/tex]

[tex]f(-5)=-17[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)}=\dfrac{7-(-17)}{3+5}=3[/tex]

[tex]f(3)=(3)^2-2=7[/tex]

[tex]f(-5)=(-5)^2-2=23[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)}=\dfrac{7-23}{3-(-5)}=-2[/tex]

From inspection of the graph:

[tex]f(3)\approx8[/tex]

[tex]f(-5) \approx 0[/tex]

[tex]\implies \textsf{Average rate of change}=\dfrac{f(3)-f(-5)}{3-(-5)} \approx \dfrac{8-0}{3-(-5)}=1[/tex]

Therefore, the Tabled Function has the greatest average rate of change in the interval [-5, 3] and so it is increasing the fastest.

The equation in the form (x + a)² = b is (x + 2)² = 16

The equation is given as:

x² + 4x = 12​

Take the coefficient of x

k = 4

Divide by 2

k/2 = 2

Square both sides

(k/2)² = 4

Add this result to both sides of x² + 4x = 12​

x² + 4x + 4 = 12​ + 4

Evaluate the sum

x² + 4x + 4 = 16

Express as a perfect square

(x + 2)² = 16

Hence, the equation in the form (x + a)² = b is (x + 2)² = 16

The airplane reaches its maximum height of 95 feet after 10 seconds

The maximum height of an object the point where the velocity of the object is zero.

Given the function that represents the height of the airplane is expressed as h(t) = -(t-10)² + 95

The maximum height is the point where h'(t) = 0

h'(t) = -2(t-10)

0 = -2t + 10

2t = 10

t = 5secs

Substitute t =10 into the function

h(5) = -(10-10)² + 95

h(5) = -0 + 95
h(5) = 95feet

Answer:$1,942.50

Step-by-step explanation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.5%/100 = 0.025 per year.

Solving our equation:

A = 1850(1 + (0.025 × 2)) = 1942.5

A = $1,942.50

The total amount accrued, principal plus interest, from simple interest on a principal of $1,850.00 at a rate of 2.5% per year for 2 years is $1,942.50.

Answer:

depends on how much beer is left

Step-by-step explanation:

45 people would it take to play a 39 minute game.

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

The percentage is defined as the ratio expressed as a fraction of 100.The percentage is denoted by sign of %.For example, if XYZ scored 46% marks in his test, it means that he scored 46 marks out of 100. It is written as 46/100 in the fraction form and 46:100 in terms of ratio.

Given that,

It takes 15 people to play a 13 minute pool game

So, a 23 minute pool game played by 15 people

A one minute pool game played by 15/13 people

The ratio of one minute pool game to people = 15 : 13

A 39 minute pool game played by number of people = 39(15/13)

A 39 minute pool game played by number of people = 45

Hence, 45 people would it take to play a 39 minute game.
