Which is the correct expansion of (3x+2)(3x^2+4)

Answers

Answer 1

Answer:6x + 3x^2 +4

depending on what your on

Step-by-step explanation:

Answer 2

Answer:

9x^3 + 6x ^2 + 12x + 8

Step-by-step explanation:

Do each individually.

First (3x^2)(3x) = 9x^3

Then (3x^2)(2) = 6x^2

Then (3x)(4) = 12x

Then (4)(2) = 8

Finally add everything together, since everything has a different exponent, then just combine like I have above.

Answers

Answer:

Find the answers below

Step-by-step explanation:

Using m<X as the reference angle

Opposite YZ = 7

Adjacent  XY = 10

Hypotenuse XZ = √149

Using the SOH CAH TOA identity

sinX = opp/hyp

sinX =YZ/XZ

sinX = 7/√149

For cos X

cos X = adj/hyp

cos X =10/√149

Using m<Z as reference angle;

Opposite XY = 10

Adjacent  YZ = 7

Hypotenuse XZ = √149

Using the SOH CAH TOA identity

sinZ = opp/hyp

sinZ =10/√149

sinZ = 7/√149

For cos Z

cosZ = 7/√149

A. -5
B. -1/5
C. 1/5
D. 5

Answers

Answer:  Choice A)  -5

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

Explanation:

The point (-2,2) is on the red f(x) line. This point is marked in black.

It corresponds to the point (-2,-10) on the g(x) blue line.

The point (-2,2) moves to (-2,-10). The x coordinate stays at x = -2. The y coordinate has gone from y = 2 to y = -10. This is a jump of "times negative 5".

-5*2 = -10

So we see that k = -5

Saying g(x) = k*f(x) is the same as g(x) = -5*f(x)

Recall that y = f(x), so saying -5*f(x) is really saying "whatever the y coordinate is on f(x), multiply it by -5 to get the corresponding y coordinate on g(x)".

Answer:

-5

y = -x + 4 (red)

y=5x -20 (blue)

-5*(-x+4) = 5x-20

Tami spins a spinner with 7 sections. The sections are numbered 1 through 7 and all sections are the same size

Answers

Answer:

1 / 7

Step-by-step explanation:

Number of sections on spinner = 7

Section is numbered 1 to 7

Since the probability of landing on each section is the same:

Probability that spinner lands on 4 :

Probability, p = Required outcome / Total possible outcomes

Required outcome = landing on 4 = 1

Total possible outcomes = (1 to 7) = 7

P(landing on 4) = 1 /7

What is the solution to the equation x/3 = 9 x=

Answers

Answer:

x = 27

Step-by-step explanation:

x/3 = 9

Multiply both sides by 3

x/3 * 3 ( the 3's cancel out and we're left with x )

9 * 3 = 27

We're left with x = 27

Answer:

27

Step-by-step explanation:

[tex]\frac{x}{3} =9\\\\\\[/tex]

In order to solve for x, we need to undo the operations. Because x is being divided, we need to multiply both sides by the same number that x is being divided by to find x.

[tex]\frac{x}{3} (3)=9(3)\\x=27[/tex]

Two of the volleyball team’s coaches and three of the players’ parents would like to

to be under 30 minutes. Explain how to write an inequality to find the possible average
length of each speech.

Answers

Answer:

5x < 30

Step-by-step explanation:

coaches = 2x

parents = 3x

total time = under 30 mins

2x + 3x < 30

5x < 30

x < 6

Answer:

Sample response: Choose a variable to represent the average speech length. If x is the variable, then the inequality would be (2+3)x < 30,="" or="">x < 30. The 2 + 3, or 5, represents the total number of people making speeches. Each one would last an average of x minutes, so we want the product of x and (2+3) to be less than 30, the time limit set by the principal.

Answer:

$321562.50

Step-by-step explanation:

Exponential growth can be modeled by the formula [tex]y = a(1+r)^{x}[/tex] , with y representing the final value, a being the starting value, r being the growth rate, and x being the number of time intervals passed.

To figure out the rate, we must use the values given from the months we have data of. Our starting value is 60,000 , ending value is 105,000 , and given that monthly sales are given, we can assume that sales grew exponentially each month. There were 4 years, or 48 months, that the store had to grow. Our formula is thus

[tex]105000 = 60000(1+r)^{48}\\[/tex]

To solve for r, we can first divide both sides by 60,000 , then put each side to the power of 1/48, resulting in

[tex]105000/60000 = (1+r)^{48}\\1.75 = (1+r)^{48}\\\\1.75^{1/48} = 1+r[/tex]

Since we know our rate, and there are 8 years/96 months between January 2005 and January 2013, we can make our starting value 105,000 , plug (1.75)^(1/48) for r and 96 for x in [tex]y = a(1+r)^{x}[/tex], and go from there.

Our final value is then

[tex]y = 105000(1.75^{1/48})^{96}\\y = 105000(1.75^{2})\\y = 321562.5[/tex]. We were able to turn 1.75^(1/48)^(96) into 1.75² using the exponent rule stating that x^y^z = x^(y*z)
