HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Gre4nikov [31]

Answer:

93° (to the nearest degree)

Step-by-step explanation:

sum of the interior angles of a triangle = 180°

Find angle C first, then subtract angle C and angle B from 180° to find angle A.

Use the sine rule \frac{sinA}{a}=\frac{sinB}{b}=\frac{sinC}{c} to find angle C:

Therefore,

              \frac{sinB}{b}=\frac{sinC}{c}

              \frac{sin38}{9}=\frac{sinC}{11}

         angle C = 48.80523914...°

Angle A = 180 - 38 - 48.80523914...°

              = 93.19476086..°

              = 93° (to the nearest degree)

Find the volume of a cone with radius 28 and height 44.
Brut [27]
The volume formula for a cone is V = 1/3 pi r^2 h.  We have everything we need to find the volume. V = 1/3 pi 28^2* 44.  Doing that math and leaving it in terms of pi you have that the volume is 11,498.67 pi units cubed.  If you multiply pi in, the answer would be 36,123.06 units cubed.

What term is used to describe the graphical representation of the change in microbial population over time?
ruslelena [56]

Answer:

The term exponential is often used.

Step-by-step explanation:

The term exponential is used to represent changes in population over time.  The idea of (positive) exponential is that the higher the number, the higher the growth. You can relate this with a population, because the higher the population, the more opportunities for it to multiply, thus, the higher it grows.

Usually the way to meassure the population of an species after certain number of years x, you use an exponential function of the form

f(x) = K_0 * a^x

For certain constants K₀ and a. K₀ is the initial population at the start of the experiment and <em>a </em>number of exponential growth. Essentially, the population of the species is multiplied by a during each year.

For example, if K₀ = 1000 and a = 2, then the population at the start of the experiment is 1000. After the first year is 1000*2 = 2000 and after the second year it is 2000*2 = 4000. Note that, not only the population grow during the years, but also the amount that the population increases also grow: in the first year it grows 1000, and between the first and second year it grows 2000.
