Answer:
R' (3,-3)
Step-by-step explanation:
This is a cubic equation so it will have a total of three roots.
there is only one change of sign so the equation will have one positive real root.
The other 2 roots will be negative and might be real or complex
Answer:
base length = 19 cm , height = 12 cm
Step-by-step explanation:
Area formula : A = (1/2)*b*h
b = h + 7 cm
A = 114 sq. cm
114 = (1/2) * (h + 7) *h
228 = hh + 7h
hh + 7h - 228 = 0
h = -7/2 + root( 49 - 4*(-228)) /2
h = -7/2 + 31/2
h = 24/2 = 12 cm
base = 12 cm + 7 cm = 19 cm
20π or 62.8 roughly
Step-by-step explanation:
Hello!
The formula for finding the circumference of a circle is 2rπ:
In that case, all we have to do is substitute 10m for our r.
2 × 10 = 20.
So circumference will be 20π.
Using 3.14 for π:
We get that 62.8 is a rough estimate for the circumference.
Really, it's 62.831..... going on forever since π is irrational.
Thus, the answer exactly is .
Hope this helps!
Answers:
a) 1/6
b) 0
Step-by-step explanation:
a) this is the way i remember
on a 6 sided dice there are <em>6</em> outcomes. 5 is 1 of those outcomes. so its 1/<em>6</em>
b) there no 7 on a six sided dice so its impossible. impossible outcomes are represented as 0
