Answer:

Step-by-step explanation: We have to find out how much centimeters of tape we need to wrap one present, so you have to divide 12 by 3=4

so you need 4 centimeters of tape to wrap one present. Now we have to find out how much tape we need for 6 presents, so we do 4x6=24.

Convert the function into intercept form. Show your work. y=-x^2+5x+36

UkoKoshka [18]

Y = -x2 + 5x + 36 → y = -(x2 -5x -36)

→ y = -(x2 - 9x +4x - 36)

→ y = -[x(x-9) + 4(x - 9)]

→ y = -(x - 9)(x + 4)

Your answer would be y=-(x-9)(x+4).

I don’t understand how to do this

schepotkina [342]

Answer:

The solution is $x =0.$

Step-by-step explanation:

The equation

$\bold{(1).}\: sin(\dfrac{3\pi }{2} +x)+sin(\dfrac{3\pi }{2} +x) =-2$

can be rewritten as

$2* sin(\dfrac{3\pi }{2} +2) =-2$

and can be further simplified to

$sin(\dfrac{3\pi }{2}+x ) =-1$ .

Now, taking the inverse sine of both sides we get:

$sin^{-1}(sin(\dfrac{3\pi }{2} +x) =sin^{-1}(-1)$

$\bold{(2).}\: \dfrac{3\pi }{2} +2 =sin^{-1}(-1)$

The value of the right side on the interval $[0,2\pi)$ is

$sin^{-1}(-1) = \dfrac{3\pi}{2} \: \:( \text{or }270^o)$ ,

which makes the equation (2)

$\dfrac{3\pi }{2}+x =\dfrac{3\pi}{2}$

solving for $x$ gives

$\boxed{x = 0}$

which is our solution.

Use the three steps to solve the problem.

Oksana_A [137]

Answer:

If the second of the three numbers is

, then the first and third are

n- 1 and n + 1 , so we find: 117 = ( n − 1 ) + n + ( n + 1 ) = 3n

Dividing both ends by

3 we find: n = 117/ 3 = 39

So the three numbers are:

38 , 39 , 40
