To find the inverse, interchange the variables and solve for y.
f^−1(x)=−25+5x/2
Answer:
The ordered pair is (1, 2) ⇒ A
Step-by-step explanation:
In the function f(x) = y
- x is the domain of the function
- y is the range of the function
- The domain is all the x-coordinates of the points lie on the graph of the function
- The range is all the y-coordinates of the points lie on the graph of the function
That means any ordered pair (x, y) satisfy the function f(x) = y, lies on the graph of the function
∵ f(x) = 2x
→ That means y = 2x
∵ x = 1
→ Substitute the value of x in the function above
∴ f(1) = 2(1)
∴ f(1) = 2
→ That means at x = 1, y = 2
∴ The ordered pair is (1, 2)
Answer:
Length of arc = 5 cm (Approx)
Step-by-step explanation:
Given:
Radius of circle = 20 cm
Angle = 1/4 radian
Find:
Length of arc
Computation:
Angle in degree = 1/4 radian × 180°π
Angle in degree = 1/4 × 180° / 22/7
Angle in degree = 14.31° Approx
Length of arc = (Ф / 360)2πr
Length of arc = (14.31 /360)2(22/7)(20)
Length of arc = 4.997 cm
Length of arc = 5 cm (Approx)
If you're solving for the length of that side just use the pythagorean theorem so the hypotenuse or your missing side equals: <span>
hypotenuse = square root ( 5.5^2 + 4.83^3 )
hypotenuse = square root (30.25 + 23.3289)
</span><span>hypotenuse = square root (53.5789)
</span><span>hypotenuse = 7.32
</span>
So, the total distance is 7.32 miles.
For this case we must solve the following linear equation:
Adding similar terms from the left side of the equation:
Subtracting
from both sides of the equation we have:
Thus, equality is not fulfilled. So the equation has no solution.
Answer:
No solution
