Answer:
x = 4 & 2
Step-by-step explanation:
-2x²+12x-16 = 0
-2(x²-6x+8) = 0 // Factor what's in the parentheses
-2(x-4)(x-2) = 0
-2(x-4) = (-2x+8)
(-2x+8) = 0 // Subtract 8 on both sides
-2x = -8 // Divide both sides by -2
x = 4
x-2 = 0 // Add 2 on both sides
x = 2

I painfully counted every square to find that a 1 by 1 square is divided into an 8 by 8 square.
K is one square above 1/2, for the second coordinate is 4.
K is also 2 to the left of 0, so the first coordinate is 2.
Therefore, the coordinates of K are (2,4).

When plotted the points and connected, it is clear that from the shape of the lines that f(x) is exponential and g(x) is linear function.
Small correction, f(1) should be 1/2, otherwise with repeat values it is not a function.The intersection of the graphs is also given, with added section of function f(x), it is clear the added point is (-3, 8) and connected with red line segment. Approximate coordinates are indicated (-2.54, 6.15)

Find C?
Answers
9514 1404 393
Answer:
C ≈ 0.00106455765168
Step-by-step explanation:
This is the sum of 13 terms of the geometric series that has 10000C/1.05 as the first term and a common ratio of 1/1.05. The sum S is given by ...
S = a1(1 -r^n)/(1 -r) . . . . a1 is the first term, r is the common ratio
Using the known values, we have ...
100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))
0.01 = C(1 -1.05^-13)/0.05
C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679
C ≈ 0.00106455765168
Answer:
C ≈ 0.00106455765168
Step-by-step explanation:
100 = (10000C/1.05)(1 -1.05^-13)/(1 -1/1.05))
0.01 = C(1 -1.05^-13)/0.05
C = 0.0005/(1 -1.05^-13) ≈ 0.0005/0.469679
C ≈ 0.00106455765168
Isabella is bouncing a rubber ball that has a density of 1.5 g/cm3 . The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?
Answers
Answer:
The mass of the rubber ball is 169.5g
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for m
m=D*V
In this problem we have
V=113 cm^3
D=1.5 g/cm^3
substitute
m.1.5*113=169.5g

A puppy’s weight increased from 12 pounds to 15 pounds. By what percentage did the puppy’s weight increase?
Answers
=======================================================
Work Shown:
A = old value = 12 pounds
B = new value = 15 pounds
C = percent change
C = [ (B-A)/A ] * 100%
C = [ (15-12)/12 ] * 100%
C = (3/12)*100%
C = 0.25*100%
C = 25%
The positive C value indicates a percent increase
So effectively, we find the difference or change in weight (B-A) and divide it over the original weight (A). That leads to 0.25 which converts to 25%
Note that,
25% of 12 = 0.25*12 = 3
This says that the puppy gained 3 pounds, which is the value of B-A
Since the puppy gained 3 pounds, the new weight is 12+3 = 15 pounds
-----------
As an alternative, we could divide the two values B over A to find that
B/A = 15/12 = 1.25
Then subtract 1 from this result: 1.25 - 1 = 0.25 = 25%
