Ndicate in standard form the equation of the line through the given points. P(0, -4), Q(5, 1)
tatuchka [14]

Answer:

y=x-4

Step-by-step explanation:

Standard form is y=mx+b

the coordinates (0, -4) tell you that the y intercept is at -4 which means b will be -4. To find slope you have to find the change in y over the change is x. 1--4=5 and 5-0=5. 5/5 is 1 so the slope, or m, is 1. x stays the same since it's the variable. it'll become y=1x-4 and since you don't have to place a coordinate of one in front of a variable, you can just write it as y=x-4

The circumference of a circular painting is 40.82 feet. What is the radius of the painting? Use 3.14 for pie and do not round yo
erica [24]

Answer:

The radius is equal to 6.5 feet.

Step-by-step explanation:

To solve this we need to know that circumference equals 2πr (where "r" is the radius). Therefore, we can make the following equation...

2πr = 40.82

πr = 20.41

3.14r = 20.41

r = 6.5

Now we know that the radius is equal to 6.5 feet.
