Answer:

Step-by-step explanation:

x cos(75) + x sin(75) = 26 newton

x ( cos(75) + sin(75) ) = 26

x = 26/ (cos75 + sin75) = 26/1.225 = 21.229

vertical component is 21.229 x sin75 = 20.5055 newton.

Perform the indicated operation. 9z^3/16xy . 4x/27z^3
ziro4ka [17]

Answer:

\frac{1}{12y}

Step-by-step explanation:

This is a multiplication problem.

We want to multiply \frac{9z^3}{16xy}\cdot \frac{4x}{27z^3}

We factor to get:

\frac{9z^3}{4\times 4xy}\cdot \frac{4x}{9\times 3z^3}

We now cancel out the common factors to get:

\frac{1}{4\times y}\cdot \frac{1}{1\times 3}

We now multiply the numerators and the denominators separately to get.

This simplifies to \frac{1}{12y}

Therefore the simplified expression is \frac{1}{12y}

The population of Adamsville grew from 7,000 to 12,000 in 5 years. Assuming uninhibited exponential growth, what is the expected
mr Goodwill [35]
We have that if we assume standard exponential growth, the equation of the population will be:7000*e^{kt} if we start counting from the moment that the population was 7000. We are given that 7000* e^{5k}=12000, namely that P(5)=12000 and we need to find 7000e^{(5+5)k}=7000e^{10k}. Since e^(10k)=e^(5k)*e^(5k), and since we can solve for e^(5k) from P(5), we have:
e^(5k)=12000/7000 and we can calculate P(10). P(10)=7000\frac{12000^2}{7000^2}= 20571 people.

X squared plus 3X -4 equals six
professor190 [17]
X^2 + 3x - 4 = 6
x^2 + 3x - 10 = 0 (Now reverse FOIL)
(x + 5)(x - 2)(Now x will equal the opposites of your numbers)
x = -5
x = 2
Hope this helped!
