Firdavs [7]

Answer:

8 hours

Step-by-step explanation:

We can use a ratio to solve

12 hours    x hours

----------   = ------------

93 dollars    62 dollars

Using cross products

12 * 62 = 93x

Divide each side by 93

12*62/93 = 93x/93

8 = x

8 hours

For a Cosine function with amplitude =0.75 and period =10 , what is y(4) ?
frez [133]

We need to find a cosine function:


y(x)=acos(bx) \\ \\ where: \\ \\ \left|a\right|=Amplitude \\ \\ Period=\frac{2\pi}{b}


The amplitude represents half the distance  between the maximum and minimum values of the function and the period goes from the x-value of one peak to the x-value of the next one. Therefore:


a=0.75 \\ \\ b=\frac{2\pi}{10}=\frac{\pi}{5}


Finally:


\boxed{y(x)=0.75cos(\frac{\pi}{5}x)}


And y(4) is:


y(4)=0.75cos(\frac{\pi}{5}\times 4) \\ \\ \therefore \boxed{y(4)=-0.60}

I need help plz thx

Answer:

Perimeter = 36 units

Step-by-step explanation:

The figure given has been labelled with letters for easy reference.

Recall: when two tangents segments meet at a point outside the circle, the two segments that are tangent to the circle are congruent to each.

Perimeter = a + b + c + d + e + f

e = 4 (given)

e = f = 4 (tangents drawn from an external point)

b = 10 - f

Substitute

b = 10 - 4

b = 6

b = a = 6 (tangents drawn from an external point)

c = 8 (given)

c = d = 8 (tangents drawn from an external point)

Perimeter = 6 + 6 + 8 + 8 + 4 + 4

Perimeter = 36 units

Find the other endpoint given the following <br> Endpoint: (5,-3) Midpoint: (7,-6)
Phantasy [73]

The answer is (9, -9) for The second midpoint.  

Let's start by calling the known endpoint L and the unknown K. We'll call the midpoint M. In order to find this, we must first note that to find a midpoint we need to take the average of the endpoints. To do this we add them together and then divide by 2. So, using that, we can write a formula and solve for each part of the k coordinates. We'll start with just x values.

(Kx + Lx)/2 = Mx

(Kx + 5)/2 = 7

Kx + 5 = 14

Kx = 9

And now we do the same thing for y values

(Ky + Ly)/2 = My

(Ky + -3)/2 = -6

Ky + -3 = -12

Ky = -9

This gives us the final point of (9, -9)
