Find the Value of k that will make the function f(x) continuous everywhere.​
cricket20 [7]

well, if that function f(x) were to be continuos on all subfunctions, that means that whatever value 7x + k has when x = 2, meets or matches the value that kx² - 6 has when x = 2 as well, so then 7x + k = kx² - 6 when f(2)

f(x)= \begin{cases} 7x+k,&x\leqslant 2\\ kx^2-6&x > 2 \end{cases}\qquad \qquad f(2)= \begin{cases} 7(2)+k,&x\leqslant 2\\ k(2)^2-6&x > 2 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ 7(2)+k~~ = ~~k(2)^2-6\implies 14+k~~ = ~~4k-6 \\\\\\ 14~~ = ~~3k-6\implies 20~~ = ~~3k\implies \cfrac{20}{3}=k

Find the 13th term of the geometric sequence 3, -15, 75, ...​
Maksim231197 [3]

Step-by-step explanation:

an = a1 + (n - 1)d \\ d = a2 - a1 \\ a1 = 3 \\ a2 =  - 15 \\ d =  - 15 - 3 =  - 18

a13 = 3 + (12)  \times ( - 18) \\ a13 = 3 - 216  \\ a13 =  - 213

Find the slope of the line that passses thruogh 1,5 and 10,9
vichka [17]

Answer:  The slope is 4/9  or -4/-9.

Step-by-step explanation:

(1,5)  

(10,9)   Find the difference in the y values and divide it by the difference in the x values.

5-9= -4

1- 10= -9

-4/-9= 4/9

so the slope is 4/9  

Using the slope we could also find the y-intercept and write the equation.

5=4/9 (1) + b    where b is the y-intercept

  5= 4/9 + b

-4/9   -4/9

b= 41/9  

Now we will have the equation  y= 4/9 + 41/9

Find the domain and range of the exponential function h(x) = –343^x. Explain your findings. As x decreases, does h increase or d
Snowcat [4.5K]

Answer:

As x decreases, h increases (but never touches)

As x increases, h decreases (but never touches)

Step-by-step explanation:

If you graphed the exponential, you would be able to see that it is stuck in the 3rd quadrant.

Domain: (negative infinity, 1)

Range: (negative infinity, 0)
