Answer:

8450 = P

Step-by-step explanation:

I = Prt

Where I is the interest , p is the principle, r is the rate and t is the time in years

2078.70 = P *8.2% * 3

Changing to decimal form

2078.70 = P *.082 * 3

2078.70 = P *.246

Divide each side by .246

2078.70/.246 = P *.246/.246

8450 = P

Answer:

y = 5cos(πx/4) +11

Step-by-step explanation:

The radius is 5 ft, so that will be the multiplier of the trig function.

The car starts at the top of the wheel, so the appropriate trig function is cosine, which is 1 (its maximum value) when its argument is zero.

The period is 8 seconds, so the argument of the cosine function will be 2π(x/8) = πx/4. This changes by 2π when x changes by 8.

The centerline of the wheel is the sum of the minimum and the radius, so is 6+5 = 11 ft. This is the offset of the scaled cosine function.

Putting that all together, you get

... y = 5cos(π/4x) + 11

_____

The answer selections don't seem to consistently identify the argument of the trig function properly. We assume that π/4(x) means (πx/4), where this product is the argument of the trig function.

Please help me with this
erma4kov [3.2K]

Answer:

3/8

Step-by-step explanation:

Find the height of the trapezoids

20 - 10 = 10

10/2 = 5

Find the area of the trapezoids

5*(20+10)/2 = 75

The formula for the area of the trapezoid is the height * the bases added together divided by 2

75*2(this is because there are 2 trapezoids) = 150

Put this to proportion of the total area of the dart board

150/20^{2} = 150/400 = 3/8

3/8 is the probability that you score 3 points
