The answer would be √32 or 4√2 (which is simplified) because of pythagoras' theorem. If we substitute a = b = 4 into it, then c must equal the root of 16 + 16, or 32.
The range of any graph are the set of all the y-values of the graph. For this graph, it goes all the way from 0 to about 3.5. I'd say the range of this graph was {0, 3.5}. Hope I could help!
The answer is 70.364. Go to Cymath and put in the exact equation above and you’ll get each step in full detail. Hope this helps!
Step-by-step explanation:
- N% of 40=10
N/100×40=10
N=10×100/40=25

Equation 1) y = x² + 10x + 11
Equation 2) y = x² + x - 7
Subtract equations from one another.
9x = 18
Divide both sides by 9.
x = 2
Plug in 2 for x in the first equation.
y = x² + 10x + 11
y = 2² + 10(2) + 11
Simplify.
y = 4 + 20 + 11
y = 35
Plug in 35 for y and 2 for x in the first equation to check your work.
y = x² + 10x + 11
35 = 2² + 10(2) + 11
35 = 4 + 20 + 11
35 = 24 + 11
35 = 35
So, we know that our answer is correct! :))
x = 2, y = 35
