Answer:
50.27m
2 π r
Step-by-step explanation:
Answer: 5 cm
Step-by-step explanation:
h = 22
l = 7
b = 5
volume of cuboid = lbh
= 22x7x5
=770 cm3
r = 7
770 = pi r^{2} h
770 = 22/7 x 49 x h
770 = 22 x 7 x h
110 = 22 x h
h = 5 cm
Neither, because the lines will be on top of each other, and so it will neither be parallel or perpendicular
hope this helps
I think that it would be 1.5 because if you multiply it by 6 it is 1.5
Answer:
Please see attached image and all steps below for both parts
Step-by-step explanation:
Task 1
The following system of equations includes a linear equation and a quadratic one:
it can be solved by using substitution in the second equation of the variable "y" by the linear expression of the first equation:
and this product of two factors will e zero when either factor is zero, that is: when x = 0, or when x = 9 [to make zero the binomial(x - 9)]
There are two solutions: x = 0 and x = 9.
When we graph both expressions in the system, we see that the line intercepts the parabola at the points (0, 2) and (9, 11). See attached image.
Task 2
Part 1:
Let's pick 30 as a number larger than 25. 30 can be written as 40 - 10
So we can use:
to calculate its square.
Part 2:
let's choose a=9 and b=10 so we use:
