A model rocket is built to scale is 3 cm = 5 m. If the model is 9.4 cm tall, how tall is the actual rocket?

Since there may be an easier way, you can find how many centimeters there may be for one meter by dividing both sides (3 cm = 5 m ) by 5.
3 \div 5 = .6 \\ 5 \div 5 = 1
So, .6 cm= 1 m
This will make it easy to divide to find the actual ticket size.
You have to find how many .6 there are in 9.4 by dividing:
9.4 \div .6 = 15 \frac{2}{3}
The rocket would be
15 \frac{2}{3}
m tall.

Compute the value of the following improper integral if it converges. If it diverges, enter INF if it diverges to infinity, MINF
Phoenix [80]

Answer:

INF for first while D for second

Step-by-step explanation:

Ok I think I read that integral with lower limit 1 and upper limit infinity

where the integrand is ln(x)*x^2

integrate(ln(x)*x^2)

=x^3/3 *ln(x)- integrate(x^3/3 *1/x)

Let's simplify

=x^3/3 *ln(x)-integrate(x^2/3)

=x^3/3*ln(x)-1/3*x^3/3

=x^3/3* ln(x)-x^3/9+C

Now apply the limits of integration where z goes to infinity

[z^3/3*ln(z)-z^3/9]-[1^3/3*ln(1)-1^3/9]

[z^3/3*ln(z)-z^3/9]- (1/9)

focuse on the part involving z... for now

z^3/9[ 3ln(z)-1]

Both parts are getting positive large for positive large values of z

So the integral diverges to infinity (INF)

By the integral test... the sum also diverges (D)

ANSWER THIS PLS!!!!
astra-53 [7]

Answer and Step-by-step explanation: With the constant velocity motion formula, we can determine constant velocity of the object in motion whose data we collected:

x = x₀ + vt

Velocity can be calculated as:

v=\frac{x-x_{0}}{t}

v=\frac{70-40}{10}

v = 3 m/s

The beginning of the data collect, object is 40m away, then x₀ = 40.

So, equation modeling the object's path is x = 40 + 3t.

What is the slope of the line that contains the points (7, -1) and (-2, -4)?
grigory [225]

Answer:

1/3

Step-by-step explanation:

Alright, so in this you want to use the slope formula: m=y2-y1/x2-x1. You plug the coordinates of the points into the formula to get the slope. (x1,y1) (x2,y2). So in this problem, 7 is x1, -1 is y1, -2 is x2, -4 is y2. So using the formula, you plug in y2 minus y1, divided by x2 minus x1.

So m (the slope) = -4- (-1) divided by -2-7.

2 negatives make a positive, so -4 + 1 is -3. -2-7 becomes -9. So this is now -3/-9. Again, 2 negatives make a positive, so this is now 3/9. Simplify and the answer is positive 1/3. Hope this helps!
