Answer:
A = 50.26 sq meters
Step-by-step explanation:
we have to find the diameter first by using the circumference:
C = πd
25.12 = πd
25.12/π = d
8 = d
this means the radius is 4
A = πr²
A = π4² or 16π
A = 50.26 sq meters
Answer:
x = 0.3 (see below)
Find the x intercept/zero.
To find x intercept/zero, subsitute H (x) = 0.
0 = 5.7 - 19x
Move the variable to the left hand side and change the symbol.
19x = 5.7
Now, divide both sides.
x = 0.3
Solution is 0.3
Alternate solution is x = 3/10.
Hope it helps!
Number the tables as follows:
1 2
3 4
Eliminate 3 and 4 immediately, because for x = 2 the y values are wrong (3 and 1).
In tables 1 and 2, the input (1) produces the correct output (-1).
So we have to determine which table agrees 100% with the system of equations given.
Comparing tables 1 and 2, row by row, we see that their contents are the same EXCEPT for the first rows. So focus on determing which of those 2 rows displays values that satisfy both given equations.
First I looked at y=2x-5, and subst. -1 for x. I got -7, which is correct in table 1 but not in table 2 (where the value would be -13).
Thus, table 1 correct represents the solution of the system of equations.
Hi, this is the notation for inclusion of all real
numbers.
We can also state numbers which are positive or negative with a sign on top of the R notation like so:
False. This number can be written as a fraction,
