Hey!


I have attached four different graphs to this answer.

The first graph represents the equation  y=2 x^{2} - 3

The second graph represents the equation y = -3 x^{2}  +2.

The third graph represents the equation y= 3 x^{2} -2.

The fourth and final graph represents y=2 x^{2} -2.

Now, at first I thought the correct answer was graph four, but then I took a closer look at the image you provided and I can tell that that was not the correct answer. You see, both the last to graphs look fairly similar, but they are different by a few points.

Your graph shows two x-intercepts that are not exactly on -1 and 1. Which explains why I though graph number four was the correct answer. But it cannot be the correct answer because graph number 4 shows two x-intercepts EXACTLY on -1 and 1.

<em>So, this means the answer is graph 3, or the equation</em>  y= 3 x^{2} -2.

Hope this helps!

tangare [24]

Answer:

7. cos(X) = 3/5 = 0.6

cos(Y) = 4/5 = 0.8

8. cos(X) = 15/17 ≈ 0.8824

cos(Y) = 8/17 ≈ 0.4706

9. cos(X) = 1/2 = 0.5

cos(Y) = (√3)/2 ≈ 0.8660

Step-by-step explanation:

The trigonometric ratio for cosine is given as follows;

Cos(\theta) = \dfrac{Adjacent\, side \, to\,  angle}{Hypothenus\, side \, length \ of\, the \  triangle}

7. The adjacent leg length to ∠X = 27

The length of the hypotenuse side of the triangle = 45

∴ cos(X) = 27/45 = 3/5 = 0.6

Cos(X) = 3/5 = 0.6

The adjacent leg length to ∠Y = 36

∴ cos(Y) = 36/45 = 4/5 = 0.8

cos(Y) = 4/5 = 0.8

8. The adjacent leg length to ∠X = 15

The length of the hypotenuse side of the triangle = 17

∴ cos(X) = 15/17 ≈ 0.8824

The adjacent leg length to ∠Y = 8

∴ cos(Y) = 8/17 ≈ 0.4706

9. The adjacent leg length to ∠X = 13

The length of the hypotenuse side of the triangle = 26

∴ cos(X) = 13/26 = 1/2 = 0.5

Cos(X) = 1/2 = 0.5

The adjacent leg length to ∠Y = 13·√3

∴ cos(Y) = 13·√3/26 = (√3)/2 ≈ 0.8660

cos(Y) = (√3)/2 ≈ 0.8660.

Help please it would help my grade alot
Alexxandr [17]

Answer:

It cooled 58.4 degrees

Step-by-step explanation:

T(t) = 68 + 144e ^(-.052t)

We want to find the value when t= 10

T(10) = 68 + 144e ^(-.052*10)

        = 68 +85.611

 T(10)         =153.611

We also need to know

T(0)= 68 + 144e ^(-.052*0)

       =68+144

        =212

We want to know how much it cools

That would be the temperature at  time 0 minus the temperature at  time 10


T(0) - T (10)

212-153.611

58.389

To the nearest tenth

58.4 degrees

irina [24]

Answer:

$3003

Step-by-step explanation:

30/100×$3,575=3000/$3,575=0.84%

0.84%/100×$3,575

84/100×3,575=$300,300/100

$3003

The sales tax in New Jersey is 6%. For a $16 book, what will the total cost be, including sales tax?
Rasek [7]
<span>The sales tax in New Jersey is 6%. For a $16 book, what will the total cost be, including sales tax?
Solutions:
=> 16 dollars is the amount of book
=> 6% is the sales tax which is equals to (6% / 100% = 0.06)
Let’s follow the formula to get the total amount to be paid.
=> 16 dollars * .06 = .96 dollars
Now, let’s add this together:
=> .96 + 16 dollars = 16.96 dollars.</span>
