2sin^2(2x) + 1 = 3sin(2x) Solve for x with exact answers. The domain is 0 ≤ x ≤ π

Answer:

Step-by-step explanation:

Area = 34.4/360⁰ * 22/7 r² = 139.6

0.30031/0.30031 r² = 139.6/0.30031

r² =√ 464.8

r = 21.560180 or 21.6

Answer:

Step-by-step explanation:

y varies with the square of x:

y = kx²

y equals 24 when x equals 10

24 = k·10²

constant of proportionality k = 0.24

when x = 20, y = 0.24·20² = 96

Answer:

79/9  or 8 7/9

Step-by-step explanation:

1+9x=80

1 +9x = 90

Subtract 1 from each side

1+9x-1 = 80-1

9x = 79

divide by 9

9x/9 = 79/9

x = 8 7/9

Answer:

Step-by-step explanation:

1+9x = 80

9x = 80-1

9x = 79

x = 79/9

or

x = 8 7/9

or

x ≈ 8.78 (x = about 8.78) rounded

Answer:

B

Step-by-step explanation:

For x<=0, the equation is 2x+2 and hence option B is the answer.

Answer:

The width is 36 feet

Step-by-step explanation:

If the width of the fence is x then its length is x+3.

The perimeter is 150 feet, so we have the equation:

2(x + x + 3) = 150

4x + 6 = 150

x = 144/4 = 36 feet

Answer:

  (8, 22)

Step-by-step explanation:

For endpoints A and B, and midpoint M, the relationship of interest is ...

  B = 2M -A

  B = 2(3, 10) -(-2, -2) = (6+2, 20+2)

  B = (8, 22)

The other end point is (8, 22).

Answer:

48 - 3X

Step-by-step explanation:

( 52+2) - 3x - 6

54 - 3x - 6    So first we deal with the numbers in brackets and that is 52 + 2 giving us 54.

54 - 6 - 3x  Then you simplify the expression that is collecting like terms so then we subtract 6 from 54

48 - 3x This is the final expression after simplifying

Answer:

16 baskets

Step-by-step explanation:

Create a proportion where x is the number of baskets that Scott made:

[tex]\frac{14}{21}[/tex] = [tex]\frac{x}{24}[/tex]

Cross multiply and solve for x:

21x = 336

x = 16

So, Scott made 16 baskets.

Answer:

(x - 2)/3

(x - 4)/-5 or (-x + 4)/5

Step-by-step explanation:

this is an inverse function, and to solve an inverse function you would :

swap x and g(x) without bringing the x coefficient with it, just simply swap the variables. Then, solve for g(x), and that's it

the first question's answer is :

g(x) = 3x + 2

x = 3(g(x)) + 2

x - 2 = 3(g(x))

(x - 2)/3 = g(x)

the second one is:

g(x) = 4 - 5x

x = 4 - 5(g(x))

x - 4 = -5(g(x))

(x-4)/-5 = g(x)

g(x) = 3x + 2

y = 3x + 2

x = 3y + 2

3y = x - 2

y = x/3 - 2/3

inverse g(x) = (x - 2) / 3

g(x) = 4 - 5x

y = 4 - 5x

x = 4 - 5y

5y = 4 - x

y = 4/5 - x/5

inverse g(x) = (4 - x) / 5

Conversion a mixed number 2 5/

to a improper fraction: 2 5/6 = 2 5/

6

= 2 · 6 + 5/

6

To find new numerator:

a) Multiply the whole number 2 by the denominator 6. Whole number 2 equally 2 * 6/

6

= 12/

6

b) Add the answer from previous step 12 to the numerator 5. New numerator is 12 + 5 = 17

c) Write a previous answer (new numerator 17) over the denominator 6.

To find new numerator:

a) Multiply the whole number 5 by the denominator 4. Whole number 5 equally 5 * 4/

4

b) Add the answer from previous step 20 to the numerator 1. New numerator is 20 + 1 = 21

c) Write a previous answer (new numerator 21) over the denominator 4.

Five and one quarter is twenty-one quarters

8 · 21

28 · 6

6

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 21/

4

is 4/

21

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, the fraction result cannot be further simplified by canceling.

In words - minus seven eighths divided by twenty-one quarters = minus one sixth.

Add: the result of step No. 2 + the result of step No. 4 = -17/

6

+ (-1/

6

) = -17 + (-1)/

6

= -18/

6

= 6 · -3/

6 · 1

= -3

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(6, 6) = 6. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 6 × 6 = 36.

In words - minus seventeen sixths plus minus one sixth = minus three.

Answer:

I need points plsss

Step-by-step explanation:

There are 4 triangles with base of 5 and height of 8.4

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 x 8.4 = 21 m^2

Multiply by 4 = 21 x 4 = 84 m^2

Area of the base = length x width = 5 x 5 = 25 m^2

Total area = 84 + 25 = 109 m^2

Answer:

Luisa processed the most accounts this week, by 1.

Step-by-step explanation:

Luisa:

15 on Monday, 22 on Tuesday and 17 on Wednesday.

So a total of 15 + 22 + 17 = 54.

Rachelle:

24 on Monday, 18 on Tuesday, 11 on Wednesday.

So a total of 24 + 18 + 11 = 53.

Who has processed the most accounts this week, and by how many?

54 - 53 = 1, so Luisa processed the most accounts this week, by 1.

The measure of angle FGE is 52.5°.

Angles of Intersecting Secants Theorem states that, If two lines intersect outside a circle, then the measure of an angle formed by the two lines is one half the positive difference of the measures of the intercepted arcs.

Thus, applying the angles of intersecting secants theorem

m∠FGE = 1/2[(100 + 35) - 30]

m∠FGE = 1/2[(105]

m∠FGE = 52.5°
