Answer:

$15.96

Step-by-step explanation:

Sales price = $19.95

Discount = 20%

Amount paid = $19.95 - ($19.95*20%) = $19.95 - $3.99 = $15.96

Answer:

$15.96

Step-by-step explanation:

The sales price is $19.95. The discount is 20%.

$19.95 - ($19.95 × 20%)

$19.95 × 20% = $3.99

$19.95 - $3.99 = $15.96

3f+2g=30 and f+2g=26
tatuchka [14]
3f + 2g = 30 . . .(1)
f + 2g = 26 . . . .(2)

(1) - (2) => 2f = 4 => f = 4/2 = 2

From (2), 2 + 2g = 26 => 2g = 26 - 2 = 24 => g = 24/2 = 12

Therefore, f = 2 and g = 12

I need help with this practice problem solving This is trigonometry from my ACT prep guide
Novay_Z [31]

Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

f(x)=A\cos (\frac{2\pi}{T}x)+b

In the given case, you have:

A = 4

T = 3π/4

b = -3

By replacing you obtain:

\begin{gathered} f(x)=4\cos (\frac{2\pi}{\frac{3\pi}{4}}x)-3 \\ f(x)=4\cos (\frac{8}{3}x)-3 \end{gathered}

Hence, the answer is:

f(x) = 4cos(8/3 x) - 3
