Answer:

7 is the answer to that jgf6bf6 reddish Ve

Answer:

{-π/2, π/2}

Step-by-step explanation:

Rewrite this as:

7sin^2 x - 14sin x + 7 = 0.  Reduce this result by dividing all terms by 7:

sin^2 x - 2sin x + 1

Temporarily replace "sin x" with y:

y^2 - 2y + 1 = 0

Solve this through factoring:  (y - 1)^2 = 0, or y - 1 = ± 0, or y = ±1

Recalling that y = sin x, we write

sin x = ±1, whose solutions are sin x = 1 and sin x = -1

The solution of sin x = 1 is π/2 and that of sin x = -1 is -π/2

and so the solution set is {-π/2, π/2}

Answer:

89

Step-by-step explanation:

Answer:

A score of 89

Step-by-step explanation:

To find the average, we'll need to add all the results and divide them by the number of her exams. To do this, we'll need to add all her scores and one more (her next score to make the average 85): we'll call that x for now.

(80 + 82 + 83 + 91 + x) ÷ 5 = 85

(336 + x)/5 = 85

Multiply 5 on both sides

336 + x = 425

x = 89

Therefore, Monica will need an 89 on her next test for her average to be 85.

I hope this helped. Good luck and keep studying!

Step-by-step explanation:

i think the awnser is 2.75

Answer:

1st side=44 cm, 2nd side= 55cm

Step-by-step explanation:

let a = '4x' , b = '5x'

h= 12cm

Area of trapezium=1/2*(a+b)h

area=594=1/2*9x*12

594*2/12=9x

594/6=9x

99=9x

99/9=11=x

therefore, 4x=4*11=44cm

             &5x=5*11=55cm

Answer:

39°

Step-by-step explanation:

Angle ABD and angle CBD are complementary angles which means they complete each other to 90°

so if CBD is 51 then ABD is 90 - 51 = 39°

Answer:

y = [tex]\frac{4}{3} x[/tex]

Step-by-step explanation:

The equation is y = [tex]\frac{4}{3} x[/tex].   To draw the line, take two points (0, 0) and (3, 4).  You can draw a straight line connecting those points.

Answer:

Step-by-step explanation:

this woukd have to make y = [tex]\frac{4}{3}[/tex]x in order for the rest to become proportional with the x axis. so im pretty sure this is correct

im not 100% on this one, because im going through something else right now, but im 87% sure that this is correct. hope this helped :)

8 + 8 = 16

16 - 14 = 12

Answer: 62.5 (assuming it flies straight up, because we don't know the speed of the bird going straight, left, right, or back.)

Step-by-step explanation:

They want to know how far the bird flies in a minute. What you do is you use the char to help you figure it out, by dividing the first row both by 2, so it would give the answer under the altitude column.

Answer:

C. 5x - 54 = 3x + 16

Step-by-step explanation:

These angles are alternate interior angles and their measurement is same

5x - 54 = 3x + 16

5x - 3x = 16 + 54

2x = 70 divide both sides by 2

x = 35

Answer:

The amount financed is $5,200

Step-by-step explanation:

Amount of finance is the price after making down payment being financed by a bank or institution or any individual to purchase an asset on some agreed terms.

Price of the car = $6,400

Down payment = $1,200

Amount financed = Purchase price - Down payment

PLacing values in the formula

Amount financed = $6,400 - $1,200

Amount financed = $5,200

Amount of finance is $5,200, Whereas total payments in 36 months are $6,344.28 against finance of $5,400 and the interest payment is $944.28 ( $6,344.28 - $5,400 ).

Answer:The particles in a solid are tightly packed and locked in place. Although we cannot see it or feel it, the particles are moving = vibrating in place.

Answer:

the movement of particles within a solid is normally slower, do to the particles being tighter together than the other classifications.
