You need to use the law of cosine:

B^2 = A^2 + C^2 - 2ACcos(b)

55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)

0.841666 = cos(b)

b = 32.68

Model Exponential Growth Question :A sample of bacteria is growing at a continuously compounding rate. The sample triples in 10

Iteru [2.4K]

Answer:

The number of bacteria $B$ after $d$ days is given by

$B = B_0 (3)^{\frac{1}{10} d}$

where $B_0$ is the initial number of bacteria.

Step-by-step explanation:

The number of bacteria $B$ in the sample triples every 10 days, this means after the first 10th day, the number of bacteria is

$B = B_0 *3,$

where $B_0$ is the initial number of bacteria in the sample.

After the 2nd 10th days, the number of bacteria is

$B = (B_0 *3)*3$

after the 3rd day,

$B =( B_0 *3*3)*3$

and so on.

Thus, the formula we get for the number of bacteria after the <em>n</em>th 10-days is

$B = B_0 (3)^n$

where $n$ is is the <em>n</em>th 10-days.

Since, $n$ is 10 days, we have

$d =10n$

$n =\dfrac{1}{10}$

Substituting that into $B = B_0 (3)^n$ , we get:

$\boxed{ B = B_0 (3)^{\frac{1}{10} d}}$

A grocer sells 50 loaves of bread each day. The current price is $0.65 per loaf. The grocer estimates that for each $0.05 price

Anit [1.1K]

If she is selling 50 loaves of bread each day for $0.65 per loaf, that is $32.50 a day.
If it goes up $0.05 then she would make $35 a day but she would sell 2 fewer so then she would make $33.60. Every $0.05 cents added, 2 fewer loaves will be sold. to get the maximum profit, the price would be at
0.95 cents per loaf because 0.95 x 38 =36.1

0.95 CENTS PER LOAF

Two positive improper fractions multiplied. Is the product sometimes, always, or never less than 1? Explain

USPshnik [31]

It is never less than 1 because if it's an improper its a whole combined into the little part so a whole times a whole is always a whole whether it has a small part too or not
