Answer:

x=3

Step-by-step explanation:

Do you mean 9(3)^x=243? Then the solution is:

9(3)^x=243

(3)^x=27

log₃((3)^x)=log₃(27)

x=3

Therefore, x=3

Answer:

NO

NO SOLUTION

Step-by-step explanation:

2t + 2e = 11  eqn 1

t + e = 6.5 eqn 2

this can be solved using simultaneous  equation

Multiply eqn 2  by 2

2t + 2e = 13

subtract eqn 1 from2

0 + 0 = 2

there is no solution

Answer: This is basic trig man, So I can help you here. First thing you need is a calculator that can do sin cos and tan, ti-84 would work best. You need to use the sin cos and tan formulas to find the edge lengths of the side. heres a helppful tip to remeber the proper way to use the formulas. SOH-CAH-TOA or sin(angle measure)= Opposite side to that angle measure divided by the hypotenuse cos(angle measure)= adjacent side (the side next to the angle) divided by the hypotenuse. and TOA or Tan(angle measure)=Opposite divided by adjacent.

Step-by-step explanation: This is a mix of Special right triangles and trig. You now know how to do the trig, look up special right triangles 60 30 90 and 90 45 45, it should show you how to do the rest of the math, since I don't recall the formulas for this off the top of my head. I am not just giving you the answers for two reasons, 1 it would take tooo long and I am already doing a quiz, which I have five minutes left to complete, and B If you cant do this for yourself you will fail the final for your course.

Answer:

120 ways

Step-by-step explanation:

To line 5 children up in a family photo, the number of possible arrangements is obtained by taking the factorial of the number of people on the line.

In this scenario, we have 5 ;

Recall;

n! = n(n-1)(n-2)(n - n-1)

5! = 5(5-1)(5-2)(5-3)(5-4)

5! = 5 * 4 * 3 * 2 * 1

5! = 120 ways

Answer:

Maybe how many people are in the park

For given situation, (e - l)(4) means, there are 92 people in the amusement park 4 hours after the gates open.

"It is an expression that defines a relationship between one variable and another variable."

For given example,

the rate at which people enter amusement park is modeled by the function

[tex]e(x) = 0.03x^3 + 2[/tex]

where the rate is measured in hundreds of people per hour since the gates opened.

The rate at which people leave the amusement park is modeled by the function

[tex]l(x) = 0.5x + 1[/tex]

where the rate is measured in hundreds of people per hour since the gates opened.

First we find the subtraction of functions [tex](e-l)(x)[/tex].

[tex]\Rightarrow (e-l)(x)=e(x)-l(x)\\\\\Rightarrow (e-l)(x)=0.03x^3 + 2-(0.5x + 1)\\\\\Rightarrow (e-l)(x)=0.03x^3+2-0.5x-1\\\\\Rightarrow (e-l)(x)=0.03x^3-0.5x+1[/tex]

For x = 4,

[tex]\Rightarrow (e-l)(4)=0.03(4)^3-0.5(4)+1\\\\\Rightarrow \bold{(e-l)(4)=0.92}[/tex]

As, the rate is measured in hundreds of people per hour

So, (e - l)(4) means, there are 92 people in the amusement park 4 hours after the gates open.

Answer:

y = - 4x + 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 , then

y = - 4x + c ← is the partial equation

To find c substitute (4, - 4) into the partial equation

- 4 = - 16 + c ⇒ c = - 4 + 16 = 12

y = - 4x + 12 ← equation of line

Answer:

-3/2 is the slope

0 is the y-intercept

Step-by-step explanation:

Start at the dot to the very left since that's where it starts. Rise/Run so first start by going down to where the line meets a place where a dot can be placed. If you go down 3 and run over 2. You get to another dot that can be placed. (Place dots where the line meets a dot in the grid if that makes sense). Also if you go down another 3 and run another 2, you get to your next coordinate. The y=intercept is just basically where the line meets the y-axis so in this case, it's 0.

Hope this helps and sorry if that didn't make that much sense, Im bad at explaining things.

Answer:

{-4, 3}

Step-by-step explanation:

To find "solutions," you must set this function equal to zero:

y = -7(x - 3)(x + 4) = 0

and then set each factor equal to 0 separately and solve each resulting equation for x:

x - 3 = 0 yields x = 3, and

x + 4 = 0 yields x = -4

Answer:

The area of the hexagon is approximately 55.43 square feet

Step-by-step explanation:

The given apothem of the hexagon, a = 4 ft.

The area of an hexagon given the apothem, 'a', is found as follows;

The area of an hexagon of side length, s, A = ((3·√3)/2)·s²

s = a·2·tan(180/n)

∴ A = ((3·√3)/2)·(a·2·tan(180/n))²

For an hexagon, n = 6

∴ A = ((3 × √3)/2) × (4 × 2 × tan(180/6))² ≈ 55.43

The area of the hexagon, A ≈ 55.43 ft.²

Answer: p = 24  − 5 q /2

Step-by-step explanation:

Answer:

[tex]p = \frac{ - 5}{2} q + 24[/tex]

Step-by-step explanation:

Let's solve for p:

[tex]2p+5q=48[/tex]

Step 1: Add -5q to both sides.

[tex]2p+5q+−5q=48+−5q[/tex]

[tex]2p=−5q+48[/tex]

Step 2: Divide both sides by 2.

[tex] \frac{2p}{2} = \frac{ - 5q + 48}{2} [/tex]

[tex]p= \frac{ - 5}{2} q+24[/tex]
