Answer:  C.  150 km²

<u>Step-by-step explanation:</u>

Use similar triangle proportion to find x:

\dfrac{x}{4.5}=\dfrac{15.3+7.4}{7.4}\\\\\\x=\dfrac{4.5(22.7)}{7.4}\\\\\\x=13.8\\\\\text{Notice that x is the diameter of the circle}\implies r=\dfrac{13.8}{2}=6.9\\\\\\\text{Find the area of the circle using }A=\pi r^2\\A=\pi (6.9)^2\\\\.\ =\pi (47.6)\\\\.\ =149.6\\\\.\ \approx150

function a and function b are linear functions. function a is represented by the table values. function b is represented by the
Kryger [21]

The y-intercept of B is greater than the y-intercept of A and the rate of change of function A is less than the rate of change of B

<h3>Linear functions </h3>

The standard linear equation is expressed as y = mx + b

For the given table;

The y-intercept occur at x = 0

y = 3x + 4

y = 3(0) + 4

y = 4

For the table;

Using the coordinate points (1, 2) and (3,10)

rate of change "m" = 10-2/3-1
m = 8/2

m = 4

Recall that y = mx + b

2 = 4(1) + b

b = -2

Hence the y-intercept of B is greater than the y-intercept of A and the rate of change of function A is less than the rate of change of B.

GrogVix [38]

Answer:

$18.15  

Step-by-step explanation:

We have been given that In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at $220 before tax.

To find sales tax paid by Yuki for her handbag purchase we will find 4.6% of $220 and 3.65% of $220 and add amount of both taxes.  

\text{Total sales tax amount}=\text{State sales tax amount}+\text{ County sales tax amount}

\text{State sales tax for handbag}=220\times\frac{4.6}{100}        

\text{State sales tax for handbag}=22\times 0.46

\text{State sales tax for handbag}=10.12

Now let us find county sales tax for handbag purchase.

\text{County sales tax for handbag}=220\times\frac{3.65}{100}

\text{County sales tax for handbag}=22\times 0.365

\text{County sales tax for handbag}=8.03

Now let us add both amount to get total tax paid by Yuki.

\text{Total sales tax}=10.12+8.03

\text{Total sales tax}=18.15

Therefore, Yuki paid $18.15 sales tax for her handbag purchase.

Which translation for: y = (x+3)^2+4<br><br> If you can't see the picture zoom in.
Savatey [412]

Answer:

The answer is B.

Step-by-step explanation:

The original graph of y = x^2 has a vertex at (0,0)

The formula for graph translations is y = (x-#)^2+#

The number inside the parentheses is a horizontal translation.

So, we are given y = (x-(-3))^2+#

The vertex of the graph moves 3 points left, since the number is negative (-3).

The number at the end of the equation is a vertical translation.

So, we are given y = (x+3)^2+4

The vertex of the graph moves 4 points up, since the number is positive (4).

The new vertex is at (-3,4)
