Answer:
![x=25](https://tex.z-dn.net/?f=x%3D25)
Step-by-step explanation:
we know that
In this problem
The value of x represent the radius of the circle
so
Applying the Pythagoras theorem in the right triangle of the figure, you can find the radius of the circle O
see the attached figure to better understand the problem
![x^{2} =20^{2}+15^{2}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D20%5E%7B2%7D%2B15%5E%7B2%7D)
![x^{2} =400+225](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D400%2B225)
![x^{2} =625](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D625)
square root both sides
![x=25](https://tex.z-dn.net/?f=x%3D25)
Answer:
AC = 15
Step-by-step explanation:
3x + 4x + 8 = 5x + 10
7x + 8 = 5x + 10
2x + 8 = 10
2x = 2
x = 1
5(1) + 10 = 15
The generic equation for a linear function can be expressed in the slope intercept form f(x) = mx + b, where m is the slope and b is the y intercept. For this problem we can first find the equation of the line. Then we substitute x = 7 to get the f(x) value, which is n at the point x = 7.
To find the equation of the linear function we first find the slope. Slope is defined as the change in f(x) divided by the change in x. As we are given a linear function, the slope at every point is the same. We can pick any two points known to find the slope.
Let's pick (3, 7) and (9, 16). The slope m is m = (16-7)/(9-3) = 9/6 = 3/2.
Now that we have the slope, we can plug in the slope and one of the points to find b. Let's use the point (3, 7).
f(x) = mx + b
7 = (1/2)(3) + b
b = 11/2
Now we can write the equation
f(x) = (1/2)x + 11/2
Plugging in x = 7 we find that f(7) = 9. n = 9
Answer: if thats a ten then its
Step-by-step explanation:
rectangle is LxW= 70
triangle is A=h(b)/b = 17.5
together it would be 87.5
i think lol
