A 12-m ladder is leaning against a wall.

Mathematics
1 answer:
Len [333]2 years ago
7 0

Answer:

Step-by-step explanation:

Use Pythagorean's Theorem for a right triangle. Your best bet when learning/visualizing word problems is to draw a picture, then learn how to visualize in your head over time.

3^2+x^2=12^2\\9+x^2=144\\x=\sqrt{135}

The radical can be further simplified because 135 is the product of 9 and 15. 9 has a perfect root of 3.

x=3\sqrt{15} meters or 11.62 meters

What is the inverse of the functiob f(x)=1/4x-12
MaRussiya [10]
Replace the f(x) with y and proceed to make x the subject:
y=1/4x-12
y+12=1/4x
To ÷1/4 on both sides, ×4 on both sides
4(y+12)=x
4y+48=x
Now swap y with x and replace the isolated x with f(x) to get the inverse function:
{f}^{ - 1}(x) = 4x + 48
