Convert 4.5% to a decimal

Answer:

[tex]g(x)=x^3-8x^2+9x+11[/tex]

Step-by-step explanation:

[tex]f(x)=-x^3-8x^2-9x+11[/tex]

When a function is reflected across the y-axis, negative x-values become positive, and positive x-values become negative.

Therefore, substitute -x in place of x in the function f(x):

[tex]g(x)=-(-x)^3-8(-x)^2-9(-x)+11[/tex]

We know that [tex](-x)^3=-(x^3)[/tex]

[tex]\implies -(-x)^3=--(x^3)=x^3[/tex]

We know that [tex](-x)^2=x^2[/tex]

[tex]\implies -8(-x)^2=-8(x)^2=-8x^2[/tex]

Also [tex]-9(-x)=+ \ 9x[/tex]

Therefore,

[tex]g(x)=x^3-8x^2+9x+11[/tex]

Answer:

12. √197

13. √89

14. 2√10

15.  (-3, 2)

16. (3/2, 0)

17. (2, -8)

18. 21

Step-by-step explanation:

12. Point 1: (-8, -2); Point 2: (6, -1)

d = √(x2 - x1)² + (y2 - y1)²

d = √(6 - (-8)² + (-1 - (-2)²

d = √(14)² + (1)²

d = √196 + 1

d = √197

13. Point 1: (-4, 5); Point 2: (4, 0)

d = √(x2 - x1)² + (y2 - y1)²

d = √(4 - (-4))² + (0 - 5)²

d = √(8)² + (-5)²

d= √64 + 25

d = √89

14. G: (-2, -3); H: (0, 3)

d = √(x2 - x1)² + (y2 - y1)²

d = √(0 - (-2))² + (3 - (-3))²

d = √(-2)² + (6)²

d = √4 + 36

d = √40

d = √4 x 10

d = 2√10

15. Point 1: (-1, -5); Point 2: (-5, 9)

Midpoint = ((x1 + x2))/2, ((y1 + y2))/2

Mid = (-1 + (-5)/2, (-5 + 9)/2

Mid = (-6)/2, (4)/2

Mid = (-3, 2)

16. Point 1: (7, -2); Point 2: (-4, 2)

Midpoint = ((x1 + x2))/2, ((y1 + y2))/2

Mid = (7 + (-4)/2, (-2 + 2)/2

Mid = (3)/2, (0)/2

Mid = (3/2, 0)

17. M:(-3, -1); Y:(-8, 6), X: (X, y)

Midpoint = ((x1 + x2))/2, ((y1 + y2))/2

X      = ((-8 + x2))            ,((6 + y2))

                ÷      = -3              ÷           = -1

                2                          2

To get rid of the 2 multiply the 2 by -3 for X and -1 for Y

X = ((-8 + x2))                      ,((6 + y2))

             ÷       = -3(2)                 ÷         = -1(2)

           2(2)                              2(2)

X = (-8 + x2) = -6, (6 + y2) = -2

           +8          +8,   -6             -6

X2 = 2, Y2 = -8

X: (2, -8)

18. QR = 8x - 51; RS = 3x - 6

8x - 51 = 3x - 6

-3x         -3x

5x - 51 = -6

     + 51   +51

5x = 45

÷5    ÷5

x = 9

QR = 8(9) - 51

QR = 72 - 51

QR = 21

RS = 3x - 6

RS = 3(9) - 6

RS = 21

(QR + RS)/2

(21 + 21)/2

42/2 = 21

QS = 21

I really hope this helps!

Answer:

x = 128

Step-by-step explanation:

49 + x + 3 = 180

52 + x =180

x + 52 = 180

x + 52 - 52 = 180 - 52

x = 128

Answer:

128

Step-by-step explanation:

49+(x+3)=180

49+x+3=180

52+x=180

x=180-52

x=128

Answer:

977

Step-by-step explanation:

The amount to equally make a whole is 100. In this case the tens has 270 so subtracting it till it can no longer be subtracted by 100 would leave you 70. you have 2(200) wholes that's basically 100s so you add 200 and 700 getting 900 and left with 70 and 7 add those two and get 77 and adding the 900 would be 977.

Answer:

No they are not.

Step-by-step explanation:

Without the angels, imagine flipping over one of the triangles and overlapping them. They may be the same shape, but they are different sizes.

Answer:

Well a parallelogram has congruent opposite sides.
We need to find the value of a here.

A shape’s angle must add up to following this equation
180(n-2) = ?

Now solve for this equation right here with “n” as “sides.

THis shape has 4 sides so 180(4-2) = 360

You have each interior angle of the parrlelogram which is 360.
Let’s solve 112 and 4b +8 first.

We know they have to be equal since opposite angles of a parrlelogram has to be equal.

112 = 4b + 8

104 = 4b
26 = b

You have b as 26.

Now solving it we know that two angles “G” and “I” are both 112.

112 *2 = 224

Thats one side done.
Now the opposite…

With 224 already being taken away subtract 360 by 224 since we figured out 360 was the amount of all the interior angles in the shape add upo to. 360 - 224 = 136

136 is the other two angles ADDED UP.

Divide it by 2 since both has to be equal and be the same.

68

Now solve for a.

2a = 68.

= 34

Answer:

34

Step-by-step explanation:

Consecutive angles of a parallelogram are supplementary

2a + 112 = 180

2a = 68

a = 34

Answer:  y = 2000(0.78)^t

This is the same as writing [tex]y = 2000(0.78)^t[/tex]

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

Explanation:

The answer above is in the form y = a*b^t

a = initial price = 2000 dollars

b = decay factor = 0.78

We have a decay factor because 0 < b < 1 and because the price decreases. The 0.78 is from the computation of 1 - 0.22 = 0.78

Meaning that if the price goes down 22%, then we keep the remaining 78%

So each year, the laptop keeps 78% of its previous price after losing 22%.

Answer:

(x+3)^2 + (y-7)^2 = 2^2

Follow the standard form of a circle, (x-h)^2 + (y-k)^2 = r^2, given that (-3,7) is (h,k) and 2 is r.

Answer:

  a = 1.5

Step-by-step explanation:

Assuming side 'a' is the short side of a right triangle with the given dimensions, we can find it using the Pythagorean theorem.

  c² = a² +b²

  a = √(c² -b²) = √(2.5² -2²) = √2.25

  a = 1.5

_____

The ratio of the given sides is 2.5 : 2 = 5 : 4. Only one right triangle has hypotenuse and long side in the ratio 5 : 4. That is the 3-4-5 triangle. This means the short side is 3/5 of the hypotenuse, or (3/5)(2.5) = 1.5

The length of side 'a' is 1.5 units.

Rewrite the inner limit as

[tex]\displaystyle \lim_{n\to\infty} \prod_{k=1}^n \left(1 + \frac{(k+1)^p}{n^{p+1}}\right) \\\\ = \exp\left(\lim_{n\to\infty} \ln \prod_{k=1}^n \left(1 + \frac{(k+1)^p}{n^{p+1}}\right)\right) \\\\ = \exp\left(\lim_{n\to\infty} \sum_{k=1}^n \ln \left(1 + \frac{(k+1)^p}{n^{p+1}}\right)\right)[/tex]

For any x > 0, we have the useful bounds

[tex]x - x^2 \le \ln(1 + x) \le x[/tex]

so that

[tex]\displaystyle \sum_{k=1}^n \left(\frac{(k+1)^p}{n^{p+1}} - \frac{(k+1)^{2p}}{n^{2(p+1)}}\right) \le \sum_{k=1}^n \ln \left(1 + \frac{(k+1)^p}{n^{p+1}}\right) \le \sum_{k=1}^n \frac{(k+1)^p}{n^{p+1}}[/tex]

In the limit, we have

[tex]\displaystyle \lim_{n\to\infty} \sum_{k=1}^n \frac{(k+1)^p}{n^{p+1}} \\\\ = \lim_{n\to\infty} \frac1n \sum_{k=1}^n \left(\frac{k+1}n\right)^p \\\\ = \int_0^1 x^p \, dx = \frac1{p+1}[/tex]

and

[tex]\displaystyle \lim_{n\to\infty} \sum_{k=1}^n \frac{(k+1)^{2p}}{n^{2(p+1)}} \\\\ = \lim_{n\to\infty} \frac1n \times \frac1n \sum_{k=1}^n \left(\frac{k+1}n\right)^{2p} \\\\ = 0 \times \int_0^1 x^{2p} \, dx = 0[/tex]

Then by the squeeze theorem, the log sum converges to 1/(p + 1), so the infinite product converges to [tex]e^{\frac1{p+1}}[/tex], as suspected.

Finally,

[tex]\displaystyle \lim_{p\to\infty} \left(e^{\frac1{p+1}}\right)^{H_p} \\\\ = \exp\left(\lim_{p\to\infty} \frac{H_p}{p+1}\right) \\\\ = \exp\left(\lim_{p\to\infty} \frac{H_p-\ln(p) + \ln(p)}{p+1}\right) = e^0 = \boxed{1}[/tex]

since Hₙ - ln(n) converges to the Euler-Mascheroni constant γ.

The given expression when written in standard form gives; 10.1 * 10⁴

A number written in standard form is usually as A * 10ⁿ

where;

A is a number bigger than or equal to 1 and less than 10

Now, we are given;

Answer:

14.58 m3

Step-by-step explanation:

here, breadth (b) = 4cm

length (l) = 6cm

volume (v) = 350cm3

height (h) = ??

we know, volume of cuboid=

length × breath× height

or, v = L× B × H

or, 350 = 6 × 4 × H

or, 350 = 24 × H

or, 350/25 = H

or 14.58 = H

therefore, H = 14.58cm3

pi is irrational

Step-by-step explanation:

rational number: a number that can be expressed as an integer or the quotient of an integer divided by a nonzero integer.  A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero, whereas an irrational number cannot be expressed in the form of fractions. Rational numbers are terminating decimals, but irrational numbers are non-terminating. Irrational Numbers Definition An irrational number is a real number that cannot be expressed as a ratio of integers, for example, √ 2 is an irrational number. Again, the decimal expansion of an irrational number is neither terminating nor recurring.
