Your answers would be c and d because angles across from the exterior angle are equal to it
Answer: I am going tot give you an example for this because I don’t like giving straight up answers ok?
Step-by-step explanation:
Lets use this conversion factor:
4 inches = 1 year
Let's find the year at 5 feet (60 inches) using the conversion factor. Set up a proportion.
4 / 60 = 1 / x
Cross multiply.
4x = 60
x = 15
At 15 years, the height is 60 inches.
We can use these as points.
x = time in years
y = height in inches
Point 1 = (1, 4)
Point 2 = (15, 60)
By looking at the points, we know that as the x values increase, so does the y values. Now the relation between the x and y values of each point is that y is 4 times as that of x. Therefore, we can establish an equation.
y = 4x
This will be the model to use to find the height in 30 years.
Answer:
Surface Area would be 200² inches.
Step-by-step explanation:
SA=2(12*9)+2(9*2)+2(12*2)
SA=2(108)+2(18)+2(24)
SA=216+36+48
SA=200² in.
(f-g)(x) = 2x² + 1 - x² + 7 = x² + 8
Answer:
1) Area:
So to find area follow the formula
a=πr^2
a=area
π= pi or 3.14 in this situation
r= radius
So we have only the diameter.
To in Find the radius you can divide the diameter by 2 and get the radius which is
84/2=42
3.14*42^2=
Area: 5538.96 ft^2
2) Circumference:
To find the circumfeence you just multiply the diameter by π or in this case 3.14.
c=πd
c= circumference
d= diameters
3.14*84=
Circumfrence: 263.76 ft
