A triangle with constant base b and height h is changing with time where h(t)=3t +1. What is the rate of change of the area of t
Keith_Richards [23]

The rate of change of the area of the triangle when t=1 is also equal to 3.

<h3>Rate of change</h3>

Given the function of height of a triangle expressed as:

  • h(t) = 3t + 1

The rate of change is expressed as

  • dh/dt = 3

The rate of change of the area of the triangle when t=1 is also equal to 3.

Confidence Interval Application Many people feel that the drying of pavement marking paint is much too slow. You spend several d
djyliett [7]

Answer:

The sample size is  n =33

Step-by-step explanation:

From the question we are told that

  The margin of error is E  =  1.5 seconds

   The standard deviation is  s =  4 seconds

 Given that the confidence level is 97% then the level of significance is mathematically represented as

      \alpha =( 100 -97)\%

=>   \alpha  =  0.03

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  2.17

Generally the sample size is mathematically represented as

    n  =[  \frac{Z_{\frac{\sigma }{2 } } *  \sigma }{E} ]^2

=> n  =[  \frac{2.17  * 4 }{1.5} ]^2

=>  n =33

i need help!!! write an equation in point-slope form of the line through point j(4, –4) with slope 4. a. y 4=4(x 4) b. y 4=4(x-4
Sergeeva-Olga [200]
Required equation is y - y1 = m(x - x1); where m = 4 and (x1, y1) = (4, -4)
y - (-4) = 4(x - 4)
y + 4 = 4(x - 4)
