Answer:

3(x^2+1)+2

Step-by-step explanation:

since g(x) is equal to x^2+1 you can substitute x^2+1 for g(x) which will be f(x^2+1). then you can substitute f(x) for 3x+2 and in the end you will get 3(x^2+1)+2

Two shapes.. a circle and a rectangle. The width of the rectangle serves as the diameter of the circle.
Length = 140 m ; Width = 68 m
Circumference of a circle = 2 π r circumference of a cirlce = 2 * 3.14 * (68m/2) = 2 * 3.14 * 34 m = 213.52
length = 2 * 140 m = 280 m
perimeter of the oval = 213.52 m + 280 m = 493.52 m

I need the mean median and mode for 7

pashok25 [27]

Answer:

mode- 1 2/3 and 2

median- 2

mean- 1.96 = 1 96/100 and simplified is 24/25

Step-by-step explanation:

mode is the number that occurs the most and those 2 numbers occur the most.

median is the middle number so you put the numbers is order from least to greatest and mark of numbers one by one on each side and then ur left with two 2's in the middle so you add them and then divide by 2 which gives you 2.

mean is all the numbers added together and then divided by how many numbers there are

-3m-1<-10 or -4+2m<-14

Liono4ka [1.6K]

Answer:

m>3 or m<-5

Step-by-step explanation:

First simplify -3m-1 < -10:

-3m < -9

m > 3 (switch direction of sign when dividing by negative number)

Then simplify -4+2m<-14:

2m<-10

m<-5

m>3 or m<-5

When Josh babysits, he chargers a flat fee of $14 plus an hourly rate of $9. How long would Josh need to babysit if he wants to

SpyIntel [72]

Answer:

$\frac{36}{7}$ hours

Step-by-step explanation:

First let's get the flat fee of 14 out of the way, because he wants to earn 86 dollars and the 14 dollar fee is the y intercept.

$86-14 = 72$

We would then divide 72 by the slope (14 per hour) to see how many hours he has to work:

$72/14 \approx5.14285714286$

I would just simplify because this decimal isn't exact

$72/14 = 36/7$

So 36/7 hours

Define the concept function and give conditions which make relation a function?

viva [34]

Answer:

A function is a relation which describes that there should be only one output for each input (or) we can say that a special kind of relation (a set of ordered pairs), which follows a rule i.e., every X-value should be associated with only one y-value is called a function.
