75%

Step-by-step explanation:

Take 9/12 and multiply it by 100 and you get the percentage of the turtles that are green.

Answer:

So, equation y=7 is parallel to x-axis. A line parallel to X axis. x axis because it is the same thing as y=0x+7 or y=7, therefore y intercept is 7 and slope is 0.

Answer:

100cm^2

Step-by-step explanation:

5×2=10 which is one side

base×height=area

10×10=100

Step-by-step explanation:

Given,

1. The given expression is [tex]\sqrt[10]{x^9}[/tex].

We need to write it into exponential form.

We know that,

[tex]\sqrt[a]{x} =x^{1/a}[/tex]

Here, a = 10

So,

[tex]\sqrt[10]{x^9}=(x^9)^{1/10}\\\\=x^{9\times \dfrac{1}{10}}\\\\=x^{9/10}\\\\=x^{0.1}[/tex]

2.

[tex](\sqrt[4]{3y} )^3\\\\=((3y)^3)^{1/4}\\\\=3^{3\times \dfrac{1}{4}}\times y^{3\times \dfrac{1}{4}}\\\\=3^{3/4}y^{3/4}[/tex]

Hence, this is the required solution.

Answer:

10

Step-by-step explanation:

-5 = 5 from the x-axis

5 = 5 from the x-axis

5 + 5 = 10

Answer:

u = -261

Step-by-step explanation:

Subtract 11 from both sides:

u/9 + 11= -8

u/9 + 11 - 11 = -18 -11

u/9 = -18 - 11

u/9 = -29

u/9 9 = -29 9

u= - 29 9

u = -261

Step-by-step explanation:

55 x 3.25 = 178.75

625-178.75 = 446.25

446.25 - 5.75 = 440.5

440.5-5.75 = 434.75

434.75-5.75 = 429

429-5.75 = 423.25

423.25-5.75 = 417.5

417.5-5.75 = 411.75

411.75-5.75 = 406

406-5.75 = 400.25

400.25-5.75 = 394.5

394.5-5.75 = 388.75

388.75-5.75 = 383

383-5.75 = 377.25

377.25-5.75 = 371.5

371.5-5.75 = 365.75

365.75-5.75 = 360

360-5.75 =354.25

354.25-5.75 = 348.5

348.5-5.75 = 342.75

342.75-5.75 = 337

337-5.75 = 331.25

331.25-5.75 = 325.5

325.5-5.75 = 319.75

319.75-5.75 = 314

314-5.75 = 308.25

308.25-5.75 = 302.5

302.5-5.75 = 296.75

296.75-5.75 = 291

291-5.75 = 285.25

285.25-5.75 = 279.5

279.5-5.75 = 273.75

273.75-5.75 = 268

268-5.75 = 262.25

262.25-11.5 = 250.75

250.75-11.5 = 239.25

239.25-11.5 = 227.75

227.75-11.5 = 216.25

216.25-11.5 = 204.75

204.75-11.5 = 193.25

193.25-11.5 = 181.75

181.75-11.5 = 170.25

170.25-11.5 = 158.75

158.75-11.5 = 147.25

147.25-11.5 = 135.75

135.75-11.5 = 124.25

124.25-11.5 = 112.75

112.75-11.5 = 101.25

101.25-11.5 = 89.75

89.75-11.5 = 78.25

78.25-11.5 =66.75

66.75-11.5 = 55.25

55.25-11.5 = 43.75

43.75-11.5 = 32.25

32.25-11.5 = 20.75

20.75-11.5 = 9.25

Step-by-step explanation:

Answer:

D. (-2, 1).

Step-by-step explanation:

y = 3x + 7

y = -2x - 3

AS the expressions on the right are both equal to y:

3x + 7 = -2x - 3

3x + 2x = -3 - 7

5x = -10

x = -2

Plug this into the first equation:

y = 3(-2) + 7

y = 1.

Answer:

D, -2, 1

Answer:

The absolute maximum is 4, and the absolute minimum is 2.

Step-by-step explanation:

We are given the function:

[tex]f(x)=x^4-3x^2+4[/tex]

And we want to find the absolute extrema of the function on the interval [-1, 1].

So, we will find the smallest and largest y-value within the interval. First, we can evaluate the function at its endpoints. So:

[tex]f(-1)=(-1)^4-3(-1)^2+4=2[/tex]

And:

[tex]f(1)=(1)^4-3(1)^2+4=2[/tex]

Our endpoints are (-1, 2) and (1, 2).

Recall that extrema only occurs at critical points. Critical points are where the derivative of the function equals 0. So, we can find the derivative of the function:

[tex]\displaystyle f'(x)=\frac{d}{dx}\left[x^4-3x^2+4\right][/tex]

Differentiate:

[tex]f'(x)=4x^3-6x[/tex]

Set the function equal to 0:

[tex]0=4x^3-6x[/tex]

Solve for x. Factor:

[tex]2x(2x^2-3)=0[/tex]

Zero Product Property:

[tex]2x=0\text{ or } 2x^2-3=0[/tex]

Solve for each case. Therefore:

[tex]\displaystyle x=0\text{ or } x=\pm\frac{\sqrt6}{2}[/tex]

The second case is outside of our interval. So we can ignore it.

Evaluate the function at x = 0:

[tex]f(0)=(0)^4-3(0)^2+4=4[/tex]

Therefore, for our function on the interval [-1, 1], the absolute maximum is 4, and the absolute minimum is 2.

Answer:

4+7/16

Answer is 11/16

Step-by-step explanation:

Transform the expression then calculate

Answer:

11/16

Step-by-step explanation:

First- make sure they have the same denominator (the number located at the bottom)

(the denominator is the least common multiple (LCM) or essentially where the numbers meet up)

^ 4 and 16 meets up at 16.

^7/16 already has 16 as the denominator, however 1/4 does not.

Therefore-

1/4 * 4/4 + 7/16 * 1/1

^ 4/16 + 7/16

(they have the same denominator, therefore when you add you DO NOT change the denominator)

4+7 is 11- and you keep the denominator

11/16 is a number which you can NOT simplify.

Therefore ^ 11/16 is your answer

This is an exponential expression with 10 as the base and 4 as the exponent.

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

Explanation:

We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.

The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.

Side note: 10^4 = 10,000 = ten thousand
