After factor by grouping 7c^4-4c^3+28c^2-16c we get c(7c-4)(c^2+4)

Step-by-step explanation:

We need to factor the term:

7c^4-4c^3+28c^2-16c

Taking c common:

7c^4-4c^3+28c^2-16c\\c(7c^3-4c^2+28c-16)

Now making groups:

c(7c^3+28c-4c^2-16)

Now factorizing by groups:

c(7c^3+28c-4c^2-16)\\=c(7c(c^2+4)-4(c^2+4))\\=c((7c-4)(c^2+4))\\=c(7c-4)(c^2+4)

So, after factor by grouping 7c^4-4c^3+28c^2-16c we get c(7c-4)(c^2+4)

Scientists are studying a bacteria sample. The function f of x equals 256. 1.15 to the x. gives the number of bacteria in the sa
My name is Ann [436]

Answer:

the number of bacteria increases at a rate of 15% each day

Step-by-step explanation:

Given the function :

f(x) = 256(1.15)^x

The function represents an exponential growth function ; comparing the equation with the general form of an exponential growth function :

f(x) = A(1 + r)^t

A = the initial value of the population, = 256

(1 + r),; r = growth rate

Therefore, to solve for r ;

1 + r = 1.15

r = 1.15 - 1 ; r = 0.15

Hence, growth rate = 0.15 = 0.15 * 100% = 15%

Hence, the number of bacteria increases at a rate of 15% each day

the volume of a pyramid whose base is aright triangle is 234 units. If the two legs of the right triangle measures 9 units and 1
Kobotan [32]

If the volume of this pyramid is 234 units, the height of the pyramid is equal to 13 units.

<h3>How to calculate the volume of a pyramid.</h3>

Mathematically, the volume of a pyramid is given by the formula:

Volume = \frac{1}{3} \times base\;area \times height

<u>For the </u><u>base area</u><u>:</u>

The area of a right triangle is given by:

A=\frac{ab}{2} \\\\A=\frac{9 \times 12}{2} \\\\A=\frac{108}{2}

A = 54 square units.

<u>Given the following data:</u>

Volume of a pyramid = 234 units.

Side lengths of right triangle = 9 and 12 units.

Now, we can calculate the height of the pyramid:

234 = \frac{1}{3} \times 54 \times height\\\\234=18h\\\\h=\frac{234}{18}

h = 13 units.
