helpp + can u add an explanation on how you got the answer? thanks!
Answer:
289
Step-by-step explanation:
f(x) = x^2+1
Let x= 4
f(4) = 4^2+1 = 16+1 = 17
f(4) ^2 =17^2 =289
Place the LETTER in the smallest set that contains that value
If f(x) = 3x+1, then f(a+h) - f(a) =
1. 03 h
2. h
3. 3 h + 2

Answer:
y intercept : if jada doesn't sell anything, she loses $250
Pos/neg interval: jada needs to sell more than 35 kilos in order to make a profit
Increase/decrease interval: the more paprika she sells, the more profit she makes
Step-by-step explanation:
y intercept is when she sells 0 kilos and is at -250 on the y axis
pos/neg interval is whether or not she is above or below 0 on the x axis (she has to be above it in order to make a profit)
The more the line is increasing, the larger profit she makes

a square vegetable garden has side lengths of 12 feet. You plant flowers in the center portion as shown. You divide the remaining space into 4 equal sections and plant tomatoes, onions, zucchini, and peppers. What is the area of the onion section?
Given :-
A square vegetable garden has side lengths of 12 feet.
You plant flowers in the center portion of the garden,a square that has side lengths of 4 feet.
You divide the remaining space into 4 equal sections and plant tomatoes, onions, zucchini, and peppers.
To Find :-
What is the area of the onion section ?
Solution :-
Given that,
→ side of square vegetable garden is = 12 feet .
So ,
→ Area of square vegetable garden = (side)² = (12)² = 144 feet².
Now, given that, inside this area, there is a square of side 4 feet reserved for flowers .
So,
→ The area of the flower section = (side)² = (4)² = 16 feet².
Therefore,
→ The rest of the garden that is intended for vegetables is = The total garden area - The flower section area = 144 - 16 = 128 feet².
Now, this remaining area is to be divided in four equal sections .
So,
→ The area of the onion section = (1/4) of remaining area = (1/4) * 128 = 32 feet². (Ans.)
Hence, The area of the onion section is 32 feet².

Where do the slope and y-intercept show up in the tables and graphs?
Answer:
Solution: The general form of the line on a graph is y = mx+c,
where y is the coordinate of the point along the y-axis,
x is the coordinate of the point along the x-axis,
m is the slope of the line or arc tan of the angle the line makes with the x-axis, and
c is the intercept the line makes on the y-axis.
Suppose we want a line having a slope of 45º with the x-axis and passes through point P (4,6), the equation of the line is
y = mx + c
6 = tan 45 * 4 + c, or
6 = 4 + c, or
c = 6–4 = 2.

Answer: -12 - 3 = -15
Explanation:
We start at -12 which goes in the first box.
Moving to the left 3 units means we subtract off 3, so that's why 3 goes in the second box.
The arrow is pointing at -15 as the final destination, which goes in the final third box.

Answer:
8
Step-by-step explanation:
You multiply the candies sold, by 8 to get the money raised.
10 times 8 is 80.
20 times 8 is 160
30 times 8 is 240
And so on.
I hope this helps!
pls ❤ and give brainliest pls
Divide money raised by candles sold:
80/10 = 8
160/20 = 8
Etc.
Each candle cost $8
You would multiply the number of candles sold by $8 to find the amount of money raised.

the diagonal of a square has a length of 10. what is the area of the square?
Answer:
50
Step-by-step explanation:
Diagonal of square = 10
Use special triangles to find the area because a square's diagonal divides the 90 degree angles into 45 degrees
45-45-90 triangle
x : x : x√2
1 : 1 : 10
10=x√2
10/√2=x, rationalize denominator and you get 5√2 as the square's side length
Area is s^2, s being the length of a side
(5√2)^2=25*2=50

The volume of a right cylindrical water tank is 5000 cubic meters. The radius of the base of the tank is 20 meters. Find the length in meters, of h, the hight of the tank.
A. 15 m B. 10 m C. 10.5 m D. 12.5 m
Answer:
D. 12.5
Step-by-step explanation:
Volume of a cylinder is V=pi r^2 h
*assuming that they already divided by pi since it isnt in their volume*
We can substitute our values...
5000 = 20^2 h
5000 = 400 h
12.5 = h

Step-by-step explanation:

Functions, f and g are given by f(x)= 3+ cos x and g(x) = 2x, x is a real number. Determine the value of c for which f(g(x))= g(f(x)) where 0[tex]\leq[/tex]x<2[tex]\pi[/tex]
The value x is equal to [tex]\pi[/tex] for which f(g(x))=g(f(x))
Given :
f(x)=3+cos(x)
g(x)=2x
To find : the value of x over the given interval [tex]0\leq x\leq 2\pi[/tex]
Apply composition of functions. Replace g(x) inside f(x) to find f(g(x))
[tex]f(g(x))=f(2x)=3+cos(2x)\\g(f(x))=g(3+cosx)=2(3+cosx)\\[/tex]
Now we set f(g(x))=g(f(x)) and solve for x
[tex]3+cos(2x)=2(3+cosx)\\3+cos(2x)=6+2cos(x)\\\cos \left(2x\right)-2\cos \left(x\right)-3=0\\\\we \; know:\ cos(2x)=2cos^2(x)-1\\-4-2\cos \left(x\right)+2\cos ^2\left(x\right)=0\\2cos^2(x)-2cos(x)-4=0\\\\divide \; by \; 2 \; and \; Factor \; left \; hand \; side\\\\cos^2(x)-cos(x)-2=0\\\\(cosx-2)(cosx+1)=0\\\cos \left(x\right)=2,\:\cos \left(x\right)=-1[/tex]
cos(x)=2 cannot be solved , so no solution
[tex]cos(x)=-1\\cos is -1 at x=180 degree\\So , x=\pi[/tex]
