Answer:
y-8x+7=0
Step-by-step explanation:
slope(m)=8
using slope intercept form of equation of staright line we get
y=mx+b
y=8*x+b
y-8x=b ................ eq(i)
since the line include the point (2,9) it satisfies the euation,
here x=2 and y=9
equation: y-8x=b
9-8*2=b
9-16=-b
-7=b
substituting the value of b in eq(i) we get
y-8x=-7
y-8x+7=0 is a required equation of the line.
C = 2(pi)r....so we are looking for the radius (r)
42 = 2 * 3.14 * r
42 = 6.28r
42/6.28 = r
6.69 = r <===
Answer:
Step-by-step explanation:
1)
a) slope: 4/3
y-intercept: (0,-5)
equation: 4/3(x)- 5
b) slope: -1/2
y-intercept: (0, 1)
equation: -1/2(x)+ 1
2)
a) slope: 4/3
y-intercept: (0,2)
equation: 4/3(x)+ 2
b) slope: -3/2
y-intercept: (0,-3)
equation: -3/2(x)- 3
Answer:
t》5 or t《-9
Step-by-step explanation:
f(t) = √(t+9)(t-5)
For a function to be defined, under the radical should be non-negative values
(t+9)(t-5)》0
Roots: 5, -9
t《-9 or t》5
