What is the average rate of change for the function f(x)=3(0.25)^x over the interval -2 ≤ x ≤ 0
diamong [38]
Answer:
-22.5


Explanation:
Use the average rate of change equation
f(b)-f(a) / b-a
f(b) = f(0) = 3(.25)^0 = 3
f(a) = f(-2) = 3(.25)^-2 = 48

(3-48)/ 0-(-2)
(-45) / 2

The product of a + 3 and –2a2 + 15a + 6 is –2a3 + xa2 + 51a + 18. What is the value of x?
geniusboy [140]
Value of x is 9 As when we multiply a + 3 by -2a2 + 15a + 6 We get (a + 3) (-2a2 + 15a + 6) -2a3 + 15a2 + 6a - 6a2 + 45a + 18 -2a3 + 9a2 + 51a + 18 If we compare the coefficients of a2, we get x = 9

There is a spinner with 12 equal areas, numbered 1 through 12. If the spinner is spun
Tomtit [17]

Answer:

1/12

Step-by-step explanation:

There is only number between 1 and 12 that is both a multiple of 5 and 2, that being 10. 10 has an equal chance out of all the other numbers that can be spun, and there are 12 numbers, so 10 has a 1/12 chance of being spun.

HELP NEEDED IMMEDIATELY! I'M GETTING DESPERATE!
TiliK225 [7]

Answer:

The number of different possible values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.

Step-by-step explanation:

Given : For an integer n, the inequality  \[x^2 + nx + 15 < 0\]  has no real solutions in x.

To find : The number of different possible values of n ?

Solution :

The given inequality is   \[x^2 + nx + 15 < 0\] have no solution then the discriminant must be less than zero.

i.e. b^2-4ac

Here, a=1, b=n and c=15

{n}^{2}  - 4 \times 1 \times 15  \: <  \: 0

{n}^{2}  - 60  \: <  \: 0  

n^2

n

n

i.e. - 7.75 \:  <  \: n \:  <  \: 7.75

The integer values are {-7,-6,-5,-4,-3,-2,-1,0,1,2,3,4,5,6,7}.
