Logan genetically engineered a new type of fir tree and a new type of pine tree. The combined height of one fir tree and one pin

e tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree. How tall are the types of trees that Logan genetically engineered?

Let f be the height of the fir trees
Let p be the height of the pine trees

We know from the problem that
f + p = 21  and 4f = 24 + p
rearrange the 2nd equation to get p = 4f - 24 and substitute into the other equation

so...
f + 4f - 24 = 21
5f - 24 = 21
5f = 45
f = 9 - height of the fir tree

substitute back into the 1st equation
9 + p = 21
p = 12 - height of the pine tree

Answer:

  $1904.76

Step-by-step explanation:

The interest formula is ...

  I = Prt . . . . interest on principal P at rate r for t years

Solving for P, we find ...

  P = I/(rt) = 200/(0.07·1.5) = 200/0.105 ≈ 1904.76

The principal amount was $1904.76.

Answer:

- 508

Step-by-step explanation:

The n th term of an arithmetic sequence is

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 28 and d = - 34 - (- 28) = - 34 + 28 = - 6, thus

a_{81} = - 28 + (- 6 × 80) = - 28 - 480 = - 508

Find the probability​ p(e or​ f) if e and f are mutually​ exclusive, ​p(e)equals 0.25​, and ​p(f)equals 0.51.
Masteriza [31]

The definition of two events being mutually exclusive (or disjoint) only means that it is not possible for the two events to occur together. Given two events, E and F, they are mutually exclusive and also mean independent.

In this case, since events E and F are mutually exclusive, therefore the probability that either E or F will occur will simply be the sum of two events.

P (E or F) = P (E) + P (F)

P (E or F) = 0.25 + 0.51

P (E or F) = 0.76

 

Therefore this means that there is a 76% probability that either E or F will occur.

What are the zeroes of the function y=3(x-a)(x+b) in terms of a and b?
juin [17]

Answer:

a, -b

Step-by-step explanation:

When x is a, the function becomes

f(a)=3(a-a)(a+b)

as you see, a-a is 0, and as your whole function is multiplied by this, it makes it 0.

f(-b)=3(-b-a)(-b+b)

As you see -b+b is 0, and once again, this would make the whole function 0.
