Given the point (5,6) and the slope of 5, find y when x=21

Answers

Answer 1

Answer: If slope is 5, 5.(x-5)=y-6 so 5x-y-19=0. When x=21, y=86.

Answer 2

Answer: $\sf{Slope =(y_2-y_1)/(x_2-x_1)}\n\n5 = (y - 6)/(21-5) \n\n5=(y-6)/(16)\n\n16(5) = y-6\n\n80 = y-6\n\ny = 80 + 6\n\n\boxed{\bf{y=86}}$

Exponential functions exhibit exponential growth (or decay). What does this mean to the graphs of these functions? a.. the graph will rise or fall more dramatically than a polynomial graph. c.. the graphs represent the population of bacteria in your mouth. b.. the graph is three dimensional. d.. the exponent in the equation is less than one

Answers

Answer:

The correct option is:

Option: a

a. the graph will rise or fall more dramatically than a polynomial graph.

Step-by-step explanation:

The most basic exponential function is a function of the form

y=b^x

where b is a positive number.

When b>1

the function grows in a manner that is proportional to its original value. This is called exponential growth.

When 0>b>1

the function decays in a manner that is proportional to its original value. This is called exponential decay.

The graph of a exponential function increases or decreases rapidly as compared to a graph of a polynomial function.

Hence, option a is the correct answer.

What is the missing term in the geometric sequence? -6,24 ,? ,384,-1536a.-204
b.-144
c.-96
d.-7

Answers

assume the missing sequence is x
so -1536 / 384 = x / 24
so x = (24* - 1536) / 384
so x = -96
the answer is C. -96

the precise and accurate answer is c which is a negative integer which is -96
