Answer:

1. Fk = 24N, Fs = 60N
2. Fk = 60N, Fs = 84N

For 3, is it saying the car weighs 9000N? In that case, you’d convert Newtons to kg. then you’d find normal force by using Fn = mg (because Fn = mass x gravity) finally since you’ve found Fn, use Fk=ukFn and Fs=usFn to find kinetic and static friction.

Explanation: My work is in the picture below. Hope this helps!

Kate is at a T-shirt sale where she can buy one and get a second one for 30% off. She wants to buy two T-shirts listed at $19 ea
gladu [14]
So in this problem we can state that each T-shirt costs S19 each. And if Kate buys two she gets a 30% off with the second shirt she buys. <span>And how much will she pay?

Solution:</span> <span><span>
1.       </span>19 for each t-shirt</span> <span><span>
2.       </span>Total of $38 if not provided with 30% off</span> 
<span><span>3.       </span>19 x 0.3 = 5.7</span> 
<span><span>4.       </span>Hence 30% of $19 is $5.7</span> 
<span><span>5.       </span>Next is we deduct $5.7 which is 30% of $19.</span> <span><span>
6.       </span>19 – 5.7 = $13.3</span> <span><span>
7.       </span>Therefore we add one shirt for $19 and the second, less 30% off which now only costs for $13.3.</span> <span><span>
8.       </span>19 + 13.3 =  32.3</span> 
<span><span>9.       </span>Conclusively, she will pay $32.3 for the shirts.</span>

Two quadratic functions are represented below.
Tpy6a [65]
To determine the maximum value of a quadratic function opening downwards, we are going to find the vertex; then the y-value of the vertex will be our maximum.
To find the vertex (h,k) (where h=x-coordinate and k=y-coordinate) of a quadratic function of the form f(x)=a x^{2} +bx+c we'll use the vertex formula: h= \frac{-b}{2a}, and then we are going to replace that value in our original function to find k.

So, in our function f(x)=- x^{2} +4x-3, a=-1 and b=4. 
Lets replace those values in our vertex formula:
h= \frac{-4}{2(-1)}
h= \frac{-4}{-2}
h=2

Now that we know the x-coordinate of our vertex, lets replace it in the original function, to get the y-coordinate:
h=f(2)=-(2^{2} )+4(2)-3
h=-4+8-3
h=1

We just prove that the vertex of f(x) is (2,1), and for the graph we can tell that the vertex of g(x) is (-2,4). The only thing left is compare their y-coordinates to determine w<span>hich one has the greater maximum value. Since 4>1, we can conclude that </span>g(x) has the greater maximum.
