If f(x) = x2 − 1, and f(2a) = 35, then what could be the value of a ?

1 answer:

5 0

f(x)=x2−1That means to find the value of the function at any value of x, we square x and subtract 1. If x=2a, we square 2a and subtract 1:f(2a)=(2a)2−1=4a2−1Now, we know that f(2a)=35so we can find the value of a:f(2a)=(2a)2−1=4a2−1=354a2−1+1=35+14a2=36a2=9a=±3

professor190 [17]

First convert all to decimal.

7/9 = 0.777
8/11 = 0.727
0.79 = 0.79
84% = 0.84
4/5 = 0.8

Now line them back up in order from least to greatest based on the decimal value.

Final answer:
8/11, 7/9, 0.79, 4/5, 84%

DIA [1.3K]

The perimeter is:
P = 2x + 2y = 80
The area is:
A = x * y
The area as a function of a variable is:
A (x) = x * (40-x)
Rewriting we have:
A (x) = 40x-x ^ 2
We derive the function:
A '(x) = 40-2x
We equal zero and clear x:
40-2x = 0
2x = 40
x = 40/2
x = 20 feet
The other dimension is:
y = 40 - x
y = 40 - 20
y = 20 feet
The area will be:
A = x * y
A = 20 * 20
A = 400 feet ^ 2
Answer:
The dimensions are:
x = 20 feet
y = 20 feet
The area is:
A = 400 feet ^ 2

MArishka [77]

Answer:

y = - 2x + (1/2 38) + 2 = y = -2x + 19x + 2 at any second and y = -2x^2 / 2 + 19/2 + 2/2 = - x^2 + 19/2 + 2 = - x (4) + 19/2(4) + 1 = -4+ 38 + 1 = 35 seconds

Step-by-step explanation: We see that 38-2ft = 36ft and y intercept = 2 and then -2x allows us to represent the starting point 2 as -2 (1) to allow a descend to our back to 0 for y one we find y intercept we know - x^2 is our simplified equation and an input into this to find the static and slowed descend back to 0 if you keep inputting at 5 and 6 you see the equation speed up Anyway at (4) substitute = 4 seconds we divide our simplified equation a = -x2 into a b c and divide each by 2 before working out the decline of the equation (as equation still represents all ascending and descending) for the 4th second as the height was already said to be at its max at 38 feet see equation in answer to find 4 as substitute for x

mel-nik [20]

9514 1404 393

Answer:

4 3-point baskets
7 2-point baskets

Step-by-step explanation:

Let x represent the number of 2-point baskets Nicoli made. Then (x -3) is the number of 3-point baskets. The total number of points is ...

2x +3(x -3) = 5x -9 = 26

5x = 35 . . . . . . add 9

x = 7 . . . . . . . divide by 5

(x -3) = 4 . . . find the number of 3-point baskets

Jokic made 7 2-point baskets and 4 3-point baskets.
