Answer:
15
Step-by-step explanation:
if 2x-10=12 then
2x=22 so
X=11
X+4= 15
Answer: Width=2.86 in.
Explanation: Since we have a proportion, we can use the equation 1.8/4.4=1.17/x.
Cross multiplying gives us 1.17*4.4=1.8x and solving for x gives us 2.86 in.
Answer:
irrational
Step-by-step explanation:
irrational because it has decimals at the end.
Answer:
a. Amplitude: 4
Period: 1
b. The maximum values occur at ![\theta=0,1,2](https://tex.z-dn.net/?f=%5Ctheta%3D0%2C1%2C2)
The minimum values occur at ![\theta=\frac{1}{2},\frac{3}{2}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B3%7D%7B2%7D)
The zeros occur at ![\theta=\frac{1}{4},\frac{3}{4},\frac{5}{4},\frac{7}{4}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B1%7D%7B4%7D%2C%5Cfrac%7B3%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B4%7D%2C%5Cfrac%7B7%7D%7B4%7D)
Step-by-step explanation:
We can see from the graph that;
.
This implies that;
.
The amplitude is 4.
The function also completed one full cycle on the interval [0,1]
The period is
![T=|1-0|=1](https://tex.z-dn.net/?f=T%3D%7C1-0%7C%3D1)
The maximum values occur at ![\theta=0,1,2](https://tex.z-dn.net/?f=%5Ctheta%3D0%2C1%2C2)
The minimum values occur at ![\theta=\frac{1}{2},\frac{3}{2}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B1%7D%7B2%7D%2C%5Cfrac%7B3%7D%7B2%7D)
The zeros occur at ![\theta=\frac{1}{4},\frac{3}{4},\frac{5}{4},\frac{7}{4}](https://tex.z-dn.net/?f=%5Ctheta%3D%5Cfrac%7B1%7D%7B4%7D%2C%5Cfrac%7B3%7D%7B4%7D%2C%5Cfrac%7B5%7D%7B4%7D%2C%5Cfrac%7B7%7D%7B4%7D)
This is where the graph intersected the x-axis.
Answer:
x=-2.5
Step-by-step explanation:
ok
sotake +9 to the other side
10x-6x=-1-9
4x=-10
divide both sides by 4x
x=-2.5
