Answer:
The area of the sector is 17/2 π
Step-by-step explanation:
pi = π
To solve this problem we first have to find the fraction that corresponds to this angle of the total, for this we must divide the angle that they give us by 2π radians, since that is the angle of a circle
(17π/9 rad) / (2π rad) = 17/18
Now we multiply the area of the circle by this fraction and we will obtain the area of the sector that we want
9π * 17/18 = 17/2 π
The area of the sector is 17/2 π
Hello :
<span>the parabola's equation is : f(x) = a(x+3)²-1
</span><span>the coefficient of the squared expression in the parabola's equation is : a
but ; f(4) = 0
0 = a(4+3)²-1
49a-1=0.....a=1/49
f(x) = 1/49(x-3)²-2</span>
The graph of g is one-fifth as steep as the graph of f.
The function g basically takes the inputs for f and multiplies them by one-fifth, which means the outputs are one-fifth times those of f. Multiplying by one-fifth makes something smaller (it's the same as dividing by five). It helps to visualize this relationship, so I've attache the graphs below.
Answer:
m2−20m+72=−3
Step 1: Subtract -3 from both sides.
m2−20m+72−(−3)=−3−(−3)
m2−20m+75=0
Step 2: Factor left side of equation.
(m−5)(m−15)=0
Step 3: Set factors equal to 0.
m−5=0 or m−15=0
m=5 or m=15
Answer:
m=5 or m=15
Answer:
$427,500 dollars
Step-by-step explanation:
Given the following question:
Initial price = 450,000
5% discount
In order to find the answer, we simply find 5% of 450,000.
![\frac{5\times450000}{100} =5\times450000=2250000\div100=22500](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ctimes450000%7D%7B100%7D%20%3D5%5Ctimes450000%3D2250000%5Cdiv100%3D22500)
![450000-22500=427500](https://tex.z-dn.net/?f=450000-22500%3D427500)
![r=427500](https://tex.z-dn.net/?f=r%3D427500)
The radio (after a 5% discount) costs "$427,500 dollars."
Hope this helps.
