there is a mistake in question that f(1)= -6

but i have answered correctly

pls mark me brainliest

Answer:

f(2)= - 5

Step-by-step explanation:

hello :

f(1)=-3

f(n)=2f(n-1)+1

n=2 : f(2) = 2f(2-1)+1 = 2f(1)+1   but f(1) = -3

so : f(2)=2(-3)+1 =-6+1=-5

What you have to do is find the area of the whole rectangle, then subtract of the empty parts:

50*48-0.5(50-41)(48)-6.5(pi(5/2)^2)-1.5pi(4^2)-pi(5^2)-pi=1899.293mm^2

Explanation:

The first subtraction is the area of the triangle.  The rest are the combined areas of the circles and semicircles (semicircles are just half the area of a circle)

Answer:

1899.293mm^2

Answer:

$338.20

Step-by-step explanation:

Find out how much Dustin gets for one hour of work, since you are given how much Dustin earns in 10 hours, you divide it by 10 (the number of hours) to find one hour,

89/10=8.9

$8.9 per hour

So 38 hours would be

8.9 x 38= $338.20

The statement that is true regarding the functions on the graph is that  f(2) = g(2).

Graphing functions is known to be the drawing of any curve that shows the function that can be seen on the coordinate plane.

Note that If a curve (graph) stands for a function, then all the point on the curve is one that satisfies the equation of the function.

Note that  the linear function Since the x - axis starts with 2 it is also true to say that the y axis will also have a positive value and as such, The statement that is true regarding the functions on the graph is that  f(2) = g(2).

Its because we need to find the number that it has grown.

so we add the number that it grew to the size it was before.

Answer: 1.85 + x = 5.30

Step-by-step explanation: If we know that Ethan planted a tree that was 1.85 meters tall from the start and several years later it's 5.30 meters tall, we know that something must have been added to the 1.85 in order to get 5.30 meters tall. Since we don't know what that value is, we can use x.

X is an example of a variable. A variable is just a letter that represents any number so in this case, it represents how much the tree has grown over a time period of several years.

So we can write this as 1.85 + x = 1.30.

Answer:

He has to get a 98 on his last test

Step-by-step explanation:

Let x represent number of rabbits and y represent number of chickens.

We have been given that Jessie told her friends that there were total 30 heads for both animals. This means that there are total 30 animals.

[tex]x+y=30...(1)[/tex]

[tex]y=30-x...(1)[/tex]

We have been given that Jessie only had chicken and rabbits. We know that a rabbit has 4 legs, so total number of legs for x rabbits would be [tex]4x[/tex].

We know that a chicken has 2 legs, so total legs of y chickens would be [tex]2y[/tex].

Since all animals has 76 legs in all, so we can represent this information in an equation as:

[tex]4x+2y=76...(2)[/tex]

Upon substituting equation (1) in equation(2), we will get:

[tex]4x+60-2x=76[/tex]

[tex]2x+60=76[/tex]

[tex]2x+60-60=76-60[/tex]

[tex]2x=16[/tex]

[tex]\frac{2x}{2}=\frac{16}{2}[/tex]

[tex]x=8[/tex]

Therefore, Jessie have 8 rabbits on his farm.

Number of chickens would be [tex]y=30-x\Rightarrow 30-8=22[/tex].

Therefore, Jessie have 22 chickens on his farm.

Step-by-step explanation:

Given

Solution of the inequality

The options are not properly presented. However, I'll solve the question without considering the options.

To simplify the given inequality, it's worth knowing that the absolute function of any inequality returns the positive form of any value it takes (whether negative or positive).

Since, we've understood that the absolute can take negative of positive, the above inequality can take the following form

-3 < X - 4 < 3

Add 4 through

4 - 3 < X - 4 + 4 < 3 + 4

1 < X < 7.

Hence, |X - 4| < 3 is equivalent to 1 < X < 7.
