Answer: 0.024\ \text{miles per sec}

Step-by-step explanation:

Given

Path is changing according to the function f(x)=0.03(10x-x^2)

Rate of change of the elevation is given by the derivative of the function

\Rightarrow f'(x)=0.03(10-2x)

At x=1\ f'(x) \ \text{is}

\Rightarrow f'(x=1)=0.03(10-2\times 1)\\\Rightarrow f'(x=1)=0.03(8)\\\Rightarrow f'(x=1)=0.24\ \text{miles per sec}

it rained nine days in the month of april .based on this ,what is the probaility that is does not rain on the first day of may?​
attashe74 [19]
<h3>Answer:     7/10</h3>

==========================================================

Explanation:

There are 30 days in April. Since it rained 9 of those days, the empirical probability of it raining in April is 9/30 = (3*3)/(3*10) = 3/10.

If we assume that the same conditions (ie weather patterns) hold for May, then the empirical probability of it raining in May is also 3/10. By "raining in May", I mean specifically raining on a certain day of that month.

The empirical probability of it not raining on the first of May is therefore...

1 - (probability it rains)

1 - (3/10)

(10/10) - (3/10)

(10-3)/10

7/10

We can think of it like if we had a 10 day period, and 3 of those days it rains while the remaining 7 it does not rain.

Find the area of a triangle with a base of 10 in. and an altitude of 14 in. (The formula for the area of a triangle is A = bh ÷
Vanyuwa [196]

Answer:

The correct option is B.

Step-by-step explanation:

The area of triangle is

A=\frac{1}{2}\times b\times h

Where, b is the base of the triangle and h is the height of the triangle.

It is given that the base of the triangle is 10 inch and the height of the triangle is 14 inch.

The area of given triangle is

A=\frac{1}{2}\times 10\times 14

A=10\times 7

A=70

Therefore the area of triangle is 70 square inch and the option B is correct.
