Answer:
1,246,193 rounded to the nearest thousands is 1,246,000
Because the digit next to the thousands place (The hundreds place) is less that 5, it is 1 therefore you keep the digit the same in the thousands place and make the rest a 0.
Answer:
1,246,000
Step-by-step explanation:
1,246,193
The 6 is in the thousands place
We look at the hundreds place
1 is in the hundreds place, Since it is 4 or less, we leave the thousands place alone.
1,246,000

calculus graph please help
Answer:
See Below.
Step-by-step explanation:
We are given the graph of y = f'(x) and we want to determine the characteristics of f(x).
Part A)
f is increasing whenever f' is positive and decreasing whenever f' is negative.
Hence, f is increasing for the interval:
[tex](-\infty, -2) \cup (-1, 1)\cup (3, \infty)[/tex]
And f is decreasing for the interval:
[tex]\displaystyle (-2, -1) \cup (1, 3)[/tex]
Part B)
f has a relative maximum at x = c if f' turns from positive to negative at c and a relative minimum if f' turns from negative to positive to negative at c.
f' turns from positive to negative at x = -2 and x = 1.
And f' turns from negative to positive at x = -1 and x = 3.
Hence, f has relative maximums at x = -2 and x = 1, and relative minimums at x = -1 and x = 3.
Part C)
f is concave up whenever f'' is positive and concave down whenever f'' is negative.
In other words, f is concave up whenever f' is increasing and concave down whenever f' is decreasing.
Hence, f is concave up for the interval (rounded to the nearest tenths):
[tex]\displaystyle (-1.5 , 0) \cup (2.2, \infty)[/tex]
And concave down for the interval:
[tex]\displaystyle (-\infty, -1.5) \cup (0, 2.2)[/tex]
Part D)
Points of inflections are where the concavity changes: that is, f'' changes from either positive to negative or negative to positive.
In other words, f has an inflection point wherever f' has an extremum point.
f' has extrema at (approximately) x = -1.5, 0, and 2.2.
Hence, f has inflection points at x = -1.5, 0, and 2.2.
Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)
Answer:
g(f(x))=x^2 + 14x + 48
Step-by-step explanation:
you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.
(g o f) (x) = g ( f(x) )
= (x+7)² – 1
= x² + 14x+49 – 1
= x² + 14x+48
If you want, (f o g ) (x) below is the solution ^_^
(f o g ) (x) = f ( g(x) )
= g(x) + 7
= x²-1 +7
= x² +6

= Introduction to elapsed time Keiko started washing at 7:28 AM and finished at 8:46 AM. How long did it take her? Give your answer in hours and minutes. min X Х o ?
Answer:
Step-by-step explanation:
At 8:28 exactly one hour had gone by.
To get to 8:46 you need to add on almost 20 minutes. which would bring it up to 8:48. Since you are 2 minutes short from :46 to :48, the correct number of minutes is 18 (48 - 2)
Answer: 1 hour and 18 minutes.

Is Canada‘s population is 1/10 of the United States and Canada‘s population is 32 million how many people live in the United States
Answer:
320M
Step-by-step explanation:
It is given that Canada's population is 1/10th of the USA's population, essentially meaning that the US's population is 10x that of Canada's. Therefore, if Canada's population is 32M, multiply 10 to that:
32,000,000 x 10 = 320,000,000
320,000,000 people live in the US.

One number is 7 more than 4 times another number if the sum of the numbers is 22 find the numbers
Answer:
3 and 19
Step-by-step explanation:
The smaller number is x. The bigger number is 4x + 7. Big number + small number= 22. x + 4x + 7 = 22. 5x= 15. x= 3.
Small number= x= 3
Big number= 4x+7= 12 + 7 = 19
There are 23 red candies, 16 blue candies,
and 10 yellow candies. What is the
probability that you will reach into the
candy bag and choose a yellow piece?
Answer:
[tex]\frac{10}{49}[/tex]
Step-by-step explanation:
There are 23 red candies, 16 blue candies and 10 yellow candies.
Which means altogether we have..
23 + 16 + 10= 49
49 candies.
To find the probability of picking a yellow piece, we know that there are 10 yellow candies out of 49 candies.
So the chances of getting a yellow piece is [tex]\frac{10}{49}[/tex]
10 YELLOW CANDIES
49 CANDIES

In a poll of 300 preschoolers, 125 said they preferred chocolate ice cream, 71 said they preferred vanilla, 100 said they preferred cookies & cream, and 4 said they had never eaten ice cream. If a pie chart were to be made showing the preference for each flavor, the central angle for the chocolate ice cream sector would be:_________
Find the percentage of the people who like Chocolate = chocolate/ total x 100
Percentage = 125/300 = 0.41666 x 100 = 41.6667 = 41.67 ( round as needed)
A full circle is 360 degrees.
The central angle = percentage of chocolate x 360:
0.416666 x 360 = 150
The central angle for chocolate is 150 degrees
if radius of circle is decreased by 50% its area is reduced by
Answer:
0.25 or 25%
Step-by-step explanation:
because the area of circle is 2πr^2 or two radius times together so that both are decreased by 50%
Which of the following is a reciprocal of 5
Hi :)
The reciprocal of 5 is 1/5.
Every number has a reciprocal except 0.
For example
5/1 is just 5 but the reciprocal of that would be 1/5.
Essentially flipping the fraction.
Answer: [tex]\frac{1}{5}[/tex]
Step-by-step explanation:
Reciprocal means the multiplicative inverse of a number. It means the numerator and the denominator which their places.
Since 5 does not have a denominator, we can keep the denominator as 1. The fraction will be [tex]\frac{5}{1}[/tex]. Now when we switch the numerator and denominator, we will get [tex]\frac{1}{5}[/tex].
14. Solve y2 + 4y - 32 = 0 using the zero product property.
O A. y = 8,4
O B. y = -8,4
O c. y = -8,6
O D. y = 3
Answer: B. y = -8, 4
Step-by-step explanation:
Given expression
y² + 4y - 32 = 0
Cross factorize the expression
y 8
y -4
Factorize the expression
(y + 8) (y - 4) = 0
Finalize the factor of the expression by the zero product property
[tex]\boxed{y=-8,4}[/tex]
