Simplify the expression –3(x 3)2 – 3 3x. what is the simplified expression in standard form? –3x2 – 18x – 27 –3x2 – 15x – 30 –3x2 3x 6 –3x2 3x – 30

12-14 is equally to 2 and here is the answer

[tex] \cos(x) = \frac{b}{h} = \frac{3.8}{6.2} \\ \cos(x) = 0.612 \\ x = \cos^ {- 1} (0.612) = 51 \degree[/tex]

Answer:

x= 61 degrees

Step-by-step explanation:

1. To use trigonometry, you need to take into consideration SOH CAH and TOA. SOH is for sine, CAH is for cosine, and TOA is for tangent.

2. Figure out which one of these you can use. In this case, that would be CAH, which means you use cosine.

3. CAH means the cosine of x equals the adjacent over the hypotenuse. Adjacent is the value that is next to the angle. The hypotenuse is the value of the slant.

4. With that in mind, all you do is plug it into a calculator like so: 3.8/6.2

5. Lastly, you take that answer, move the decimal point up two places, and that's your answer.

Answer:

  f(0) = 243 . . . cats at the start

Step-by-step explanation:

The exponential function tells you the number of cats after t years is ...

  f(t) = 243(1/3)^t

When t=0, the exponential factor is 1, so the value of the function is the multiplying constant.

  f(0) = 243

This means there were 243 stray cats in town when the animal control program started.

Answer:

D. 7.5 inches

Step-by-step explanation:

So, we can find the ratio of the big triangle to the small one by dividing the values of the hypotenuse.

So, 18/6 = 3

Big:small = 3:1

So, using this we can make an equation to find AD.

Let's say ED=x.

AD is basically ED (x) + AE (5).

Since ED is part of the small triangle, and AD is part of the big one, we can use the 3:1 ratio from above.

So, [tex]\frac{x+5}{x}[/tex]=3.

Multiply both sides by x, getting x+5 = 3x.

Subtract the x:                            -x        -x

And you get 5=2x, giving you 2.5 = x.

However, we're not done yet, as 2.5 is the value of ED, but we need AD.

Remember, AD is = ED + AE.

So, AD = 2.5 + 5.

Finally, AD =  7.5

Answer:

the distributive property

Answer: distributive property

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

It is asking for the intercept.

y = x + 3 becomes y - x = 3

multiply it by two, so it becomes -2x + 2y = 6. Then add it to the other equation, and solve for y.

2x + 4y = 60

(2x + 4y) + (-2x + 2y) = 60 +6

6y = 66

y = 11

Plug in the known y into the the easiest equation.

11 = x +3

x = 8

Intercept: (8, 11)

Answer:

Equation 1 matches with number 9.

Equation 2 matches with number 7.

Equation 3 matches with number 1.

Equation 4 matches with number 3.

Equation 5 matches with number 5.

Step-by-step explanation:

Equation 1:  −9x > −9

−9x > −9

Divide both sides by −9.

-9x/-9 = -9/-9

Since −9 is negative, the inequality direction is changed.

x < 1

x < 1 matches with the graphed solution of number 9.

So, Equation 1 matches with number 9.

Equation 2: 2x + 6≥ −2

2x + 6≥ −2

Step 1: Subtract 6 from both sides

2x + 6 − 6 ≥ −2 − 6

2x ≥ −8

Step 2: Divide both sides by 2

2x/2 ≥ −8/2

Step 3: Simplify

x  ≥  -4

x  ≥  -4 matches with the graphed solution of number 7.

So, Equation 2 matches with number 7.

Equation 3: x − 9 < −5

x − 9 < −5

Step 1: Add 9 to both sides.

x − 9 + 9 < −5 + 9

Step 2: Simplify

x < 4

x < 4 matches with the graphed solution of number 1.

So, Equation 3 matches with number 1.

Equation 4: −6x < −12

−6x < −12

Divide both sides by -6

-6x/-6 < -12/-6

Since −6 is negative, the inequality direction is changed

x > 2

x > 2 matches with the graphed solution of number 3.

So, Equation 4 matches with number 3.

Equation 5: -7x + 20 > 55

-7x + 20 > 55

Step 1: Subtract 20 from both sides.

−7x + 20 − 20 > 55 − 20

Step 2: Simplify

−7x > 35

Step 3: Divide both sides by -7.

-7x/-7 > 35/-7

Step 4: Simplify

x < -5

Since −7 is negative, the inequality direction is changed

x < -5 matches with the graphed solution of number 5.

So, Equation 5 matches with number 5.

Answer:

C. $0.19/ounce

Step-by-step explanation:

We know that 16 ounces = 1 pound but we have 5 pounds,

So, we do 5 times 16.

We get 80 (ounces)  and we divided ounces by total cost ($15.25)

We get our answer:

$0.19/ounce

Answer:

WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in

Step-by-step explanation:

VOLUME = (W+3)*(W-2)*W = 52

W*(W^2 +W - 6) = 525

SOLUTION BY TRIAL & ERROR

TRIAL 1 : LET W = 5; 5(25+5–6) = 120

TRIAL 2 : LET W=10; 10(100+10–6) = 1040

TRIAL 3 : LET W = 8; 8(64+8–6) = 528 OK

ANSWER WIDTH ‘W’ = 8 in; LENGTH = 11 in AND HEIGHT = 6 in

Answer:

5.8

Step-by-step explanation:

Pythagorean Theorem:

You have the side 6 and 3. To find x you must make the right triangle.

6-1=5. So the longer side of the tri is 5. Now we will solve:

3^2+5^2=9+25=34. Now we have to square root 34.

[tex]\sqrt{34}[/tex] is approximately = 5.8

Answer:

Step-by-step explanation:

Fame age be x and sister's age = y

Five years ago:

Fame's age = x - 5

His sister's age = y -5

[tex]x -5 =\dfrac{1}{6}*(y-5)\\\\[/tex]

Multiply the entire equation by 6

[tex]6*(x-5)=6*\dfrac{1}{6}(y-5)\\[/tex]

6x- 6*5  = y-5

6x - 30 = y - 5

6x  -30 + 5 = y

y = 6x - 25--------------(I)

Three year after:

Fame's age = x + 3

His sister's age = y + 3

2*(x +3) = y + 3

2x + 6   = y + 3

2x + 6 -3 = y

y = 2x + 3 -------------(II)

Substitute y = 6x - 25 in equation (II)

6x - 25 = 2x + 3

Add 25 to both sides

6x  = 2x + 3 + 25

6x  = 2x + 28

Subtract 2x from both sides

6x - 2x = 28

       4x = 28

Divide both sides by 4

x = 28/4

x = 7

Substitute x = 7 in equation (I)

y =6x - 25

y = 6*7 - 25

  = 42 - 25

y = 17

Fame's age = 7 years

His sister's age = 17 years

4) Let the distance between X and Y be D

Time take by Wie = distance÷ speed

                             [tex]= \dfrac{D}{75}[/tex]

Time taken by Wary = distance ÷ speed

                                  [tex]=\dfrac{D}{80}[/tex]

Time difference = 10 minutes.

As Wary drives in high speed that Wie, he takes less time

[tex]\dfrac{D}{75}-\dfrac{D}{80}= \dfrac{10}{60}\\\\[/tex]

LcM = 1200

[tex]\dfrac{16D}{75*16}-\dfrac{15D}{85*15}=\dfrac{1}{6}\\\\\\\dfrac{16D-15D}{1200}=\dfrac{1}{6}\\\\\\\dfrac{D}{1200}=\dfrac{1}{6}\\\\\\D=\dfrac{1}{6}*1200\\\\\\[/tex]

[tex]\huge\boxed{\sf y = 3}[/tex]

Step-by-step explanation:

Given that:

[tex]\displaystyle y \propto \frac{1}{x}[/tex]

Converting proportionality into equality

[tex]\displaystyle y = \frac{k }{x}[/tex]   ------------------------- (1)

We know that:

y = 18 when x = 4

Put in Eq. (1)

[tex]\displaystyle 18 = \frac{k}{4} \\\\Multiply \ 4 \ to \ both \ sides\\\\18 \times 4 = k\\\\72 = k\\\\ \boxed{k = 72}[/tex]

Now,

y = ? when x = 24

Put in Eq. (1)

[tex]\displaystyle y = \frac{72}{24} \\\\\boxed{y = 3}[/tex]

[tex]\rule[225]{225}{2}[/tex]

The answer will be the power multiplied to 8.64 should have an exponent of 0.

The given expressions are

[tex]=\dfrac{8.64\times 10^1}{1.25\times 10^5}[/tex]

[tex]=(\dfrac{8.64}{1.25}) (\dfrac{10^1}{10^5} )[/tex]

[tex]=6.912\times10^{-4}[/tex]

The power of the number multiplied to 8.64 is 1 which will make it 86.4

So this power of the number should be 0

Thus the answer will be the power multiplied to 8.64 should have an exponent of 0.

See below.  Veronica's thinking is incorrect.  I've included what she is thinking, but the correct thinking is more useful, as noted below.

Step-by-step explanation:

I don't know what Veronica is thinking, other than:

(398 x 18) = (400*18 - 18)

She should be thinking:

(398 x 18) = (400 x 18) - (2*18).  The "2" is for the two extra groups of 18 that she will have when multiplying 400 x 18, instead of 398 x 18.

again, in a geometric sequence every term is created by mutilated the previous term by a constant factor.

-192 × f = 48

f = 48/-192 = -1/4

here it seems to be clear now that your teacher starts counting at a1 (and not a0).

a1 = -192

a2 = a1 × -1/4 = -192 × -1/4 = 48

a3 = a2 × -1/4 = a1 × -1/4 × -1/4 = -192 × 1/16 = -12

an = -192 × (-1/4)^(n-1)

a6 = -192 × (-1/4)⁵ = -192 × -1/1024 = 3/16
