Answer:

0.17

Step-by-step explanation:

You need to divide the distance biked by the amount of time taken to bike 4.25 of a mile. Ignore the of a mile, that isn't needed. so then you divide 4.25 by 25 and get?

0.17 for average speed/0.17 mpm or miles per minute

Hope this helped!

The function h(x)=x^2+3 and g(x)=x^2-6. if g(x)=h(x)+k, what us the value of k

lutik1710 [3]

Answer:

The value of k is -9

Step-by-step explanation:

Subsitute

g(x)=h(x)+k

$(x^2-6)=(x^2+3)+k$

$x^2-6=x^2+3+k$

subtract $x^2+3$ from both sides (or add $-x^2-3$ to both sides)

$-9=k$

$k=-9$

A frying pan has a radius of 14 centimeters. What is the circumference of the frying pan? Use 22 over 7 for 3.14

katen-ka-za [31]

To find the circumference calculate pi x the diameter of the circle.
Since the radius is 14, the diameter is 28. 3.14 x 28 = about 87.96

Let f(x)=7x-13. Find f^-1(x).

vitfil [10]

Ok but allow my humble self to use $y$ instead of $f(x)$ .

We have,

$y=7x-13$

If you wanna know what the inverse is swap the values of x and y,

$x=7y-13$

And now solve for y,

$x+13=7y\implies\boxed{y=f^{-1}(x)=\frac{x+13}{7}}$ .

Hope this helps.
