The diameter is basically half of the circumference. Which the circumference is 8 so the answer is
B) 4cm
Answer:
1. 4y = 3x - 8
2.y-7 = -2(x + 4)
Step-by-step explanation:
1. The general equation form is;
y = mx + b
m is slope b is y-intercept
so we have;
y= 3/4x - 2
Multiply through by 4
4y = 3x -8
2. The point-slope form is;
y-y1 = m(x-x1)
y-7 = -2(x + 4)
Answer:
About 14
Step-by-step explanation:
For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)
The sides that make the right angle are legs which is A and B
The other side is the hypotenuse which is C
So you set it up as
11(11) + b(b) = 18(18)
121 + b(b) = 324
324 - 121 = 203
so b(b) = 203
but 203 is b squared so you need to find the square root of 203 which is about 14.2478.
If you round that it is 14
Check
11(11) + 14(14) = 18(18)
121 + 196 = 324
317 = 324
so about
Start by subtracting 2 from both side which gives you [-3x<9] then divide by -3 which gets you [x<-3] so the answer is B
Answer:
27
Step-by-step explanation:
(5+√2)²
you distribute the ² in the ()
so 5²+√2²
5²=25
√2²=2 because the √ and ² cancel each other out and you get 2
so now you have
25+2
which equals
27
