Question: What is 35 percent of 40?

Percentage solution with steps:

Step 1: Our output value is 40.

Step 2: We represent the unknown value with $x$x.

Step 3: From step 1 above,$40=100\%$40=100%.

Step 4: Similarly, $x=35\%$x=35%.

Step 5: This results in a pair of simple equations:

$40=100\%(1)$40=100%(1).

$x=35\%(2)$x=35%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{40}{x}=\frac{100\%}{35\%}$
40
x=
100%
35%

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{40}=\frac{35}{100}$
x
40=
35
100

$\Rightarrow x=14$⇒x=14

Therefore, $35\%$35% of $40$40 is $14$ B. 14%

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.
