Here’s the graph of y=2x+7 where a point on the graph is (-2,3)
Answer:
Option C.
Step-by-step explanation:
The given function is
![f(x)=(\frac{1}{6})^x+2](https://tex.z-dn.net/?f=f%28x%29%3D%28%5Cfrac%7B1%7D%7B6%7D%29%5Ex%2B2)
We need to find the domain and range of the function.
Domain is the set of input values.
The given function is an exponential function. This exponential function is defined for all real values of x. So,
Domain : {x | x is a real number}
Range is the set of output values.
We know that
is always greater than 0.
![(\frac{1}{6})^x>0](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B6%7D%29%5Ex%3E0)
Add 2 on both sides.
![(\frac{1}{6})^x+2>0+2](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B6%7D%29%5Ex%2B2%3E0%2B2)
![f(x)>2](https://tex.z-dn.net/?f=f%28x%29%3E2)
![y>2](https://tex.z-dn.net/?f=y%3E2)
So, the rage of the function is
Range: {y | y > 2}
Therefore, the correct option is C.
Length = L
New length = L+0.1L= 1.1 L
Width = W
New width = W - (W/100)p= W-pW/100= (100W-pW)/100=W(100-p)/100
Area =A = LW
New area = A - 0.12A = 0.88A
New area = new width*new length = 1.1L*W(100-p)/100 = 1.1A(100-p)/100
New area = 0.88A
New area = 1.1A(100-p)/100
1.1A(100-p)/100 = 0.88A
1.1(100-p)/100 = 0.88
1.1(100 - p) = 88
100 - p = 80
p = 20
Answer C) 20.
Answer:
the number of days taken is 11
Step-by-step explanation:
The computation of the number of days expected to sell 44 bundt cakes as follows:
Given that
It takes every 5 days to sell 20 bundt cakes
So for 44 bundt cakes it would take
= 44 × 5 days ÷ 20
= 11 days
hence, the number of days taken is 11
