Answer:
It's easy
Step-by-step explanation:
An exponential equation always has x as an exponent so just look for it
Ex:x+2=0(quadratic) Ex:2^x=0(exponential)
Answer:
y = -2x + 12
Step-by-step explanation:
The point-slope equation for a line has the following format:
y = mx + b
In which m is the slope and b is the y-intercept(value of y when x = 0).
(1,10)
This means that when x = 1, y = 10. So
10 = m + b
(5,2)
This means that when x = 5, y = 2. So
2 = 5m + b
From the first equation, b = 10 - m. So
2 = 5m + 10 - m
2 = 4m + 10
4m = -8
m = -2
And
b = 10 - m = 10 - (-2) = 10 + 2 = 12
So
y = -2x + 12
Radius = 15/2 = 7.5
Volume of cone: pi(r)^2*h/2
= pi(7.5)^2*23/2
pi(56.25) * 23/2
(3.14)(56.25)(23)/2 = 2,031 inches
Answer:
7, 11
Step-by-step explanation:
because those sides are congruent so their measurs are equal
3a+7=4a find a
b+11=2b find b
7=4a-3a, subtract 3a from both sides so a=7
11=2b-b, subtract b from both sides so b=11
