Answer:
6 units
Step-by-step explanation:
The formula for a trapezoid is ((b1+b2)/2)h.
Here, we see b1 = 8 and b2 = 17.
If the area of the trapezoid is 75, we can make the equation :
75 = ((8+17)/2)x , where we would solve for x.
First, we simplify the right side of the equation :
75 = (25/2)x
Multiply both sides by 2 to get rid of the "/2"
150 = 25x
Then divide both sides by 25.
6=x
A 7” pizza means its diameter, so you take the diameter X pi, or 7 X 3.14 9.85
So the answer is 10”
You could type in -0x+Y=-3 or 0x-Y=3 if you want x to be positive
The line of the graph has a slope of 0 so if you put it in y intercept form it would be
y=0x-3 so if you subtract x from both sides you would get -0x+Y=-3 and that would put the equation into standard form. I’m not 100% sure if it’s correct so I’m hoping it’s correct
Answer:
cos 78⁰.
Step-by-step explanation:
Use cos 2A = cos^2 A - sin^2 A
so cos^2 39 - sin^2 39 = cos (2*39) = cos 78.
It is the smallest part of the number
