Answer:
55
Step-by-step explanation:
There are 11 tens in 110, so 11 times 5 is 55.
5. Answer: see explanation
<u>Step-by-step explanation:</u>
If the roots are m and 3m, then x = m and x = 3m
⇒ x - m = 0 and x - 3m = 0
⇒ (x - m)(x - 3m) = 0
⇒ x² - 4mx + 3m² = 0
Since x² + px + q = 0 then p = -4m and q = 3m²
3p² = 3(-4m)² 16q = 16(3m²)
= 3(16m²) = 48m²
= 48m²
3p² = 48m² = 16q ⇒ 3p² = 16q

6. Answer: 8 or 18
<u>Step-by-step explanation:</u>
The Area of the entire rectangle (A = L × w) is 12 × 10 = 120
The Area of the shaded region is 72, so the Area of the non-shaded region is 120 - 72 = 48.
There are two non-shaded triangles.
- Bigger non-shaded Δ: L = 12-x, w = 10 ⇒

- Smaller non-shaded Δ: L = x, w = x ⇒

Combine the Areas of both triangles and set it equal to the Area of the non-shaded region:

Area of ΔBEF:

Which Problem Do You Need Help With?
Answer:
you can combine like term such as x or 2x, but not variables with different exponents like x and x squared.
Step-by-step explanation:
Answer:
Domain is ![[0,18]](https://tex.z-dn.net/?f=%5B0%2C18%5D)
Average rate of change of bacteria per minute is -3333.33.
Step-by-step explanation:
Domain is the possible values of
.
From the graph, it's clear that the
values ranges from 0 to 18 as the end points of the graph are
and 
So, domain of the function is
.
Now, average rate of change is negative as there is bacteria decay.
Average rate of change is given as the negative ratio of y intercept to the x intercept.
Here, x-intercept is 18 and y-intercept is 60000.
So, average rate of change is given as,

Therefore, average rate of change of bacteria per minute is -3333.33.
