The area of a right triangle is 1/2*base height. The base is 6 and the height is 8, 6*8 = 48. After that, we multiple 48 by 1/2 which is 24. This is the are of the top and bottom triangles on #5.
Answer:
f
Step-by-step explanation:
lt's a composition of two small functions
It kind of looks like your missing something in you problem. But if f(x) = 3 is correct, then it doesn't matter what x is the answer is always going to be 3. So f(4.5) = 3. Most of the time though f(x) means a function of x, so there is an x in the problem. For example: f(x) = 3x, then f(4.5) = 3*4.5 = 13.5.
The cost of 1 apple is 0.75, because the dot is halfway between 0.5 and 1.
The cost of 3 apples is 2.25, because the dot is halfway between 2 and 2.5.
Hope my answer helped u :)
Step-by-step explanation:
1/2, 2, 9/2, ....
equivalent with :
½, 4/2, 9/2, ...
the rule is : Un = n²/2
so, U10= 10²/2 = 100/2= 50
