So what i do is take 25 cents off every dollar, so 0.25x24.95=6.24 so you subtract 6.24 from 24.95 you get 18.71. So Shirley's hat cost her $18.71 plus tax

The sale price is $6.24 because you divide 24.95 by .25 which is 25%.<span />

To two decimal places, find the value of k that will make the function f(x) continuous everywhere. f of x equals the quantity 3x

Fiesta28 [93]

Given function is

$f(x)=\left\{\begin{matrix}3x+k & x\leq -4 \\ kx^2-5 & x> -4\end{matrix}\right.$

now we need to find the value of k such that function f(x) continuous everywhere.

We know that any function f(x) is continuous at point x=a if left hand limit and right hand limits at the point x=a are equal.

So we just need to find both left and right hand limits then set equal to each other to find the value of k

To find the left hand limit (LHD) we plug x=-4 into 3x+k

so LHD= 3(-4)+k

To find the Right hand limit (RHD) we plug x=-4 into

$kx^2-5$

so RHD= $k(-4)^2-5$

Now set both equal

$k(-4)^2-5=3(-4)+k$

$16k-5=-12+k$

$16k-k=-12+5$

$15k=-7$

$k=-\frac{7}{15}$

k=-0.47

<u>Hence final answer is -0.47.</u>

Alexander is a high school basketball player. In a particular game, he made some two point shots and some three point shots. Ale

andrezito [222]

Answer:

2 three points shots and 4 two points shots

Step-by-step explanation:

Let x be the number of three points shots.

Alexander made twice as many two points shots as three points shots, so the number of two points shots is 2x.

Amount earned in three points shots $=3\cdot x$

Amount earned in two points shots $=2\cdot (2x)=4x$

Total score $=3x+4x=7x$

Alexander scores a total of 14 points, then

$7x=14\\ \\x=2\\ \\2x=2\cdot 2=4$
