Answer:

3. 18 meters.

4. A= 6. 25cm^2 and P= 10 cm

5. 16 feet and 3 feet.

Step-by-step explanation:

3. base= 2 (A/h)

2 (72/8) = 18

4. A= side^2

2.5^2 = 6.25

P= 4 sides

2.5 x 4= 10

5. 16x3= 48

Write in descending order.<br> 360t + 10t3 - 120t2

erastovalidia [21]

Answer:

30t - 120t² + 10t³

Step-by-step explanation:

30t + 10t³ - 120t²

In order of degrees of function, t³ > t² > t

So in terms of order of decreasing order, we have to rearrange the equation to

30t - 120t² + 10t³ likewise in terms if increasing degree of function,

10t³ - 120t² + 30t

The space shuttle flight control system called PASS (Primary Avionics Software Set) uses four independent computers working in p

tigry1 [53]

Answer:

$f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}$

Step-by-step explanation:

Recall that a <em>probability mass function</em> defined on a discrete random variable X is just a function that gives the probability that the random variable equals a certain value k

$f_X(k)=P(X=k)$

In this case we have the event

“The computer will ask for a roll to the left when a roll to the right is appropriate” with a probability of 0.003.

Then we have 2 possible events, either the computer is right or not.

Since we have 4 computers in parallel, the situation could be modeled with a binomial distribution and the probability mass function

$f_X(k)=\binom{4}{k}0.003^k0.997^{4-k}$

This gives the probability that k computers are wrong at the same time.

Pam bought 50 kg of sugar. She used 10 kg of sugar. What percentage of sugar was left? (step by step answer would be appreciated

galben [10]

Answer:

80%

Plz with steps .. it's very hard can anyone plz

liubo4ka [24]

Answer:

Step-by-step explanation:

$\displaystyle\ \lim_{n \to a} \dfrac{\sqrt{2x}-\sqrt{3x-a} }{\sqrt{x}-\sqrt{a}} =\frac{0}{0} \\\\we\ can \ use\ Hospital's\ Rule\\\\\\f(x)=\sqrt{2x}-\sqrt{3x-a} \qquad f'(x)=\dfrac{2}{2*\sqrt{2x}} -\dfrac{3}{2*\sqrt{3x-a}} \\\\g(x)=\sqrt{x} -\sqrt{a} \qquad g'(x)=\dfrac{1}{2\sqrt{x}} \\\\\\\displaystyle\ \lim_{n \to a} \dfrac{\sqrt{2x}-\sqrt{3x-a} }{\sqrt{x}-\sqrt{a}} =\lim_{n \to a} \dfrac{\dfrac{2}{2*\sqrt{2x}} -\dfrac{3}{2*\sqrt{3x-a}} }{\dfrac{1}{2\sqrt{x}} }\\\\$

$\displaystyle \lim_{n \to a} \dfrac{2\sqrt{x} }{\sqrt{2x}} -\dfrac{3*\sqrt{x} }{\sqrt{3x-a}} =\lim_{n \to a} \dfrac{2 }{\sqrt{2}} -\dfrac{3*\sqrt{x} }{\sqrt{3x-a}}\\\\\\=\dfrac{2}{\sqrt{2}} -\dfrac{3*\sqrt{a} }{\sqrt{2a}}\\\\\\=\dfrac{2}{\sqrt{2}} -\dfrac{3}{\sqrt{2}}\\\\\\=-\ \dfrac{1}{\sqrt{2}}\\\\$
