Answer:
x = (-9)/5
Step-by-step explanation:
Solve for x:
(-2 x)/9 = 2/5
Hint: | Multiply both sides by a constant to simplify the equation.
Multiply both sides of (-2 x)/9 = 2/5 by -9/2:
(-9 (-2) x)/(2×9) = (-9)/2×2/5
Hint: | Express (-9)/2×(-2)/9 as a single fraction.
(-9)/2×(-2)/9 = (-9 (-2))/(2×9):
(-9 (-2))/(2×9) x = (-9)/2×2/5
Hint: | Express (-9)/2×2/5 as a single fraction.
(-9)/2×2/5 = (-9×2)/(2×5):
(-9 (-2) x)/(2×9) = (-9×2)/(2×5)
Hint: | In (-9 (-2) x)/(2×9), divide -9 in the numerator by 9 in the denominator.
(-9)/9 = (9 (-1))/9 = -1:
(-2-1 x)/2 = (-9×2)/(2×5)
Hint: | In (-(-2) x)/2, divide -2 in the numerator by 2 in the denominator.
(-2)/2 = (2 (-1))/2 = -1:
--1 x = (-9×2)/(2×5)
Hint: | Multiply all instances of -1 in -(-x).
(-1)^2 = 1:
x = (-9×2)/(2×5)
Hint: | Cancel common terms in the numerator and denominator of (-9×2)/(2×5).
(-9×2)/(2×5) = 2/2×(-9)/5 = (-9)/5:
Answer: x = (-9)/5
Answer:
[tex] \frac{ - 2}{9} x = \frac{2}{5} \\ x = \frac{2}{5} \times \frac{9}{(- 2)} \\ \boxed{x = \frac{(-9)}{5}}✓[/tex]
x=-9/5 is the right answer.A circle has a diameter of 4 meters.
What is its perimeter (to the nearest hundredth)?
What is its area (to the nearest hundredth)?
m^2
Answer:
Step-by-step explanation:
r = d/2
r = 4/2
r = 2
pi = 3.14
Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 2
Circumference = 12.56
Area = pi r^2
Area = 3.14 * 2^2
Area = 4 * 3.14
Area = 12.56

Answer:
17 unitsStep-by-step explanation:
BE is midsegment of ACDF
BE = 1/2(CD + FA)2(3x + 3) = 6x - 16 + 4x - 106x + 6 = 10x - 2610x - 6x = 6 + 264x = 32x = 8Similarly, FA is midsegment of BEZW
FA = 1/2(BE + WZ)WZ = 2FA - BEWZ = 2(4x - 10) - (3x + 3)WZ = 8x - 20 - 3x - 3WZ = 5x - 23Substitute x with 8:
WZ = 5*8 - 23 = 40 - 23 = 17Write 34% as a fraction or mixed number in simplest form

Answer:
x^9 -20x^7 -6x^3 3x^2 13
Step-by-step explanation:
Standard form for polynomials is to order the degrees of the number from highest to lowest, left to right. So, knowing this, we can infer that it goes x^9 - 20x^7 - 6x^3 + 3x^2 + 13. The degree is 9 (highest exponent), and the leading coefficent (number in front of/multiplying highest degree var) is 1.
Answer: (x^9)+(-20x^7)+(-6x^3)+(3x^2)+13
Step-by-step explanation:
Standard form would just be to organize the polynomial in descending order of the degree (..._^3+_^2+_^1+constant)

Answer:
D) 54
Step-by-step explanation:
Put the numbers where the variables are and do the arithmetic.
2[(x -1) +2xy]
= 2[(4 -1) +2(4)(3)]
= 2[3 +24]
= 2(27) = 54 . . . . matches choice D
Answer:
54Step-by-step explanation:
We know that:
Given expression: 2[(x - 1) + 2xy]x = 4y = 3Solution:
2[(x - 1) + 2xy]=> 2[(4 - 1) + 2(4)(3)]=> 2[3 + 2(4)(3)]=> 2[3 + 24]=> 2[27]=> 54Hence, Option D is correct.

(a) What is wrong with the following equation? x2 + x − 42 x − 6 = x + 7 (x − 6)(x + 7) ≠ x2 + x − 42 The left-hand side is not defined for x = 0, but the right-hand side is. The left-hand side is not defined for x = 6, but the right-hand side is. None of these — the equation is correct. (b) In view of part (a), explain why the equation lim x → 6 x2 + x − 42 x − 6 = lim x → 6 (x + 7) is correct. Since x2 + x − 42 x − 6 and x + 7 are both continuous, the equation follows. Since the equation holds for all x ≠ 6, it follows that both sides of the equation approach the same limit as x → 6. This equation follows from the fact that the equation in part (a) is correct. None of these — the equation is not correct.
Answer:
Attached please find answer
Step-by-step explanation:
= (x² + x - 42) / (x - 6)
= [x² + (7x - 6x) - 42] / (x - 6)
= [x² + 7x - 6x - 42] / (x - 6)
= [(x² + 7x) - (6x + 42)] / (x - 6)
= [x(x + 7) - 6(x + 7)] / (x - 6)
= [(x + 7)(x - 6)] / (x - 6)
= x + 7 → when x approches 6
= 6 + 7
= 13
Other method:
Lim (x² + x - 42) / (x - 6)
x→ 6
When x → 6, there is an indeterminate expression because: 6 - 6 = 0
Do you know the l'Hôpital's rule, when x → a:
Lim [ f(x) / g(x) ] = Lim [ f'(x) / g'(x) ]
f(x) = x² + x - 42
f'(x) = 2x + 1
g(x) = x - 6
g'(x) = 1
= f'(x) / g'(x)
= (2x + 1)/1
= 2x + 1 → when x approches 6
= 12 + 1
= 13

I am not 100% sure but it is better than nothing.
0.62 as a percent
(STEP BY STEP)
Answer:
0.62 = 0.62 × 100/100 = (0.62 × 100)/100 = 62/100 = 62%;
In other words:
1) Multiply that number by 100.
2) Add the percent sign % to it.
Answer:
62%
Step-by-step explanation:
You would take the decimal and move it to the right two spaces then add the percent sign in replace of the decimal.
.62 → 6.2 → 62. → 62%

Integrate [tex]e^{4x}\sqrt{1+e^{2x} } dx[/tex] please show work so i can learn
Answer:
[tex](\frac{(1+e^{2x}) ^{\frac{5}{2} } }{{5}} + \frac{(1+e^{2x} )^{\frac{3}{2} } }{{3}} )+C[/tex]
Step-by-step explanation:
Step(i):-
Given that the function
f(x) = [tex]e^{4x} \sqrt{1+e^{2x} }[/tex]
Now integrating on both sides, we get
[tex]\int\limits{f(x)} \, dx = \int\limits{e^{4x} \sqrt{1+e^{2x} } dx[/tex]
= [tex]\int\limits{e^{2x} e^{2x} \sqrt{1+e^{2x} } dx[/tex]
Step(ii):-
Let [tex]1 + e^{2x} = t[/tex]
[tex]e^{2x} = t -1[/tex]
[tex]2e^{2x}dx = d t[/tex]
[tex]e^{2x}dx = \frac{1}{2} d t[/tex]
= [tex]\int\limits{( \sqrt{1+e^{2x} }) e^{2x} e^{2x} dx[/tex]
= [tex]\int\limits {\sqrt{t}(t-1)\frac{1}{2} dt }[/tex]
= [tex]\frac{1}{2} \int\limits {\sqrt{t} (t) -\sqrt{t} ) dt }[/tex]
= [tex]\frac{1}{2} \int\limits {(t^{\frac{1}{2} } t^{1} +t^{\frac{1}{2} } ) } \, dx[/tex]
[tex]= \frac{1}{2} \int\limits {(t^{\frac{3}{2} } +t^{\frac{1}{2} } ) } \, dx[/tex]
= [tex]\frac{1}{2} (\frac{t^{\frac{3}{2} +1} }{\frac{3}{2}+1 } + \frac{t^{\frac{1}{2} +1} }{\frac{1}{2}+1 } )+C[/tex]
= [tex]\frac{1}{2} (\frac{t^{\frac{3}{2} +1} }{\frac{5}{2} } + \frac{t^{\frac{1}{2} +1} }{\frac{3}{2} } )+C[/tex]
= [tex]\frac{1}{2} (\frac{t^{\frac{5}{2} } }{\frac{5}{2} } + \frac{t^{\frac{3}{2} } }{\frac{3}{2} } )+C[/tex]
= [tex](\frac{(1+e^{2x}) ^{\frac{5}{2} } }{{5}} + \frac{(1+e^{2x} )^{\frac{3}{2} } }{{3}} )+C[/tex]
Final answer:-
= [tex](\frac{(1+e^{2x}) ^{\frac{5}{2} } }{{5}} + \frac{(1+e^{2x} )^{\frac{3}{2} } }{{3}} )+C[/tex]

Find the radius, and the approximate circumference and area of the circle below. (Use 3 for \pi)
Answer:
Circ=37.704, Area= 112.112
Step-by-step explanation:
Circumference= pi *Diameter
Taking pi=3.142, Diameter=12
Circ=3.142*12=37.704
Area= pi * r^2
Area= 3.142*6*6=112.112

Solve the triangle. A = 32°, a = 19, b = 14 (1 point) B = 23°, C = 125°, c ≈17.6 Cannot be solved B = 23°, C = 125°, c ≈29.4 B = 23°, C = 145°, c ≈23.5
Answer:
The answer is below
Step-by-step explanation:
Given the triangle with: A = 32°, a = 19, b = 14
The sine rule states that for a triangle with lengths of a, b and c and the corresponding angles which are opposite the sides as A, B and C, then the following rule holds:
[tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]
Given, that for triangle ABC; A = 32°, a = 19, b = 14. therefore:
[tex]\frac{a}{sinA}=\frac{b}{sinB}\\\\\frac{19}{sin(32)}=\frac{14}{sin(B)}\\\\sin(B)=\frac{14*sin(32)}{19} \\\\sin(B)=0.39\\\\B=sin^{-1}(0.39)\\\\B=23^o[/tex]
A + B + C = 180° (sum of angles in a triangle)
32 + 23 + C = 180
55 + C = 180
C = 180 - 55
C = 125°
[tex]\frac{a}{sin(A)}=\frac{c}{sin(C)}\\\\\frac{19}{sin(32)}=\frac{c}{sin(125)} \\\\c=\frac{19*sin(125)}{sin(32)} \\\\c=29.4[/tex]
Answer:
B = 23°, C = 125°, c ≈29.4
