Answer:

The number of positive real zeros is 2 or 0

Step-by-step explanation:

Given

f(x)=x^5+3x^2-4x+2

Required

Number of positive real zeros

Using Descartes rule of signs;

We write out the signs in front of each term;

Sign = + + - +

Count the number of times the sign alternate; i.e. from positive to negative and from negative to positive

From positive to negative, we have: 1 (i.e. + - )

From negative to positive, we have: 1 (i.e. - +)

Add up the count

count = 1+1

count = 2

<em>Hence, the number of positive real zeros is 2 or 0</em>

Find the length of the hypotenuse
denpristay [2]

Answer: The answer is “10cm”

Step-by-step explanation: To get to this answer we first need to know the formula for find the hypotenuse which is a^2 + b^2 = c^2. A and B are the two sides in this case a and b are 8 cm and 6 cm. Then you plug in the values into the equation, it looks like this 8^2 + 6^ = c^2 once you solve you get 64 + 36 = c. When you add 64 and 36 you get 100 but their is one more step. You must find the square root of 100 which is 10. So your answer for the hypotenuse is “10cm”

Does anyone know the answer to this? I can't understand why it isn't -7.​
faltersainse [42]

The value of 18x + 9∆x - 7 based on the limit given will be 18x - 7.

<h3>How to calculate the value?</h3>

From the information given, it should be noted that we simply want to calculate the value of x.

This will be:

18x + 9∆x - 7

It was stated that ∆x = 0

Therefore, we'll put this into the equation.

This will be:

18x + 9∆x - 7

= 18x + 9(0) - 7

= 18x -7
