kobusy [5.1K]

Answer:

202.90

Step-by-step explanation:

If 187.90 is the price before the sales tax, you will multiply it by the 0.08 tax which will give you 15.032. You take 15.032 and add it to 187.90 because that is the sales tax. And after you add it and round to the nearest cent you get 202.90

How do I find the domain of f(x)=5x^2+4. When 0&lt;=x&lt;=2<br><br> #54
Blizzard [7]

Hi

if 0 ≤ x ≤ 2

0^2\leq x^2\leq 2^2

Multiplied by 5..... 5×0^2 \leq 5x^2\leq 5×2^2

add 4  .........5×0^2+4 \leq 5x^2+4\leq 5×2^2+4

so ........4\leq 5x^2+4\leq 24

In the diagram below, AB and TC are tangent to 0. Which equation could be solved to find x, the measure of AC?
LekaFEV [45]

The  equation that could be solved to find x, the measure of AC is 58 = 1/2(238 -x)

<h3>Circle theorem</h3>

The given diagram shows two intersecting lines tangential to a circle at points A and C.

Using the theorem that states, the measure of the angle at the vertex is equal to the half of the difference of the measure of the intercepted arcs.

Mathematically;

<B = 1/2(arcADC - arcAC)

58 = 1/2(238 -x)

Hence the  equation that could be solved to find x, the measure of AC is 58 = 1/2(238 -x)
