I guess that is 1:10
Hope ur help !;(
Ans(a):
Given function is 
we know that any rational function is not defined when denominator is 0 so that means denominator x+4 can't be 0
so let's solve
x+4≠0 for x
x≠0-4
x≠-4
Hence at x=4, function can't have solution.
Ans(b):
We know that vertical shift occurs when we add something on the right side of function so vertical shift by 4 units means add 4 to f(x)
so we get:
g(x)=f(x)+4
We may simplify this equation but that is not compulsory.
Comparision:
Graph of g(x) will be just 4 unit upward than graph of f(x).
Ans(c):
To find value of x when g(x)=8, just plug g(x)=8 in previous equation
4x-3x=-1-16
x=-17
Hence final answer is x=-17
Answer:
Step-by-step explanation:
You have no grounds for making a statement like that. There are a variety of reasons why you might not get immediate answers. Be patient.
I will do the second part of this question (finding the first three numbers):
a(4) = a(3)*(-3) + 2 = -148, so a(3)*(-3) = -150 and a(3) = -50
a(3) = 50
a(2) = a(3)*(-3) + 2 = 50, so -3*a(3) = 48 and a(d) = -16
a(1) = a(2)*(-3) + 2 = -16, so a(2)*(-3) = -18 and a(1) = 6
The procedure for finding a(5), a(6) and a(7) is exactly the same.
Answer:
Step-by-step explanation:
To calculate the lateral surface of this shape we must divide it into 3 parts :
- Part 1 : the half cylinder with the radius r=15
We must calculate its perimeter P1 :
P1 = (15*2)*π/2 = 30*π*(1/2)=15π
- Part 2 : the half cylinder with the radius r=12-5=7
We must calculate its perimeter P2:
P2= (7*2)*π/2=14*π*(1/2)= 7π
We won't calculate its perimeter because it has some common sides with the cylinders .
Let P3 be the perimeter of what's remaining from the cube
P3=12+5= 17
Now the total perimeter : Pt
Pt= 15π+7π+17= 22π+17
The lateral surface : Ls
Ls= (22π+29)*8= 784.92 m²
