What is the slope intercept form of the perpendicular line to the line with (-2,7), (0,1) and (2,-5) points
MAVERICK [17]

Answer:

Step-by-step explanation:

Slope of line through the three points is -3.

Slope of any perpendicular through the line is ⅓.

(0,1) is one of the points on the line, so the y-intercept is 1.

Slope-intercept equation for line of slope ⅓ and y-intercept 1:

y = ⅓x+1

f(x)=(2x−1)(3x+5)(x+1) has zeros at x= -5/3, x= -1 and x= 1/2 What is the sign of f on the interval -5/3
Crazy boy [7]

The sign of f on the interval -5/3 is negative

<h3>How to determine the sign?</h3>

The function is given as:

f(x)=(2x−1)(3x+5)(x+1)

The zeros of the function are

x= -5/3, x= -1 and x= 1/2

Next, we plot the graph of the function

At x = -5/3, the function approaches negative infinity

This means that the sign of f on the interval -5/3 is negative

g Two teams compete in the NBA (National Basketball Associa- tion) championshipseries. The team who wins four games out of seven
Firlakuza [10]

Answer: The required probability is 0.32.

Step-by-step explanation:

Since we have given that

Probability of winning team A over B = 0.7

Probability of losing team A over B = 0.3

Number of matches = 7"

So, using the "Binomial distribution" :

We get that

P(X=5)=^7C_5(0.7)^5(0.3)^2=0.32

Hence, the required probability is 0.32.
