Using a table of values, determine the solution to the equation below to the nearest fourth of a unit.
gayaneshka [121]
Let's call f(x) = 2x - 4 and g(x) = 3⁻ˣ + 1.

<span>First, you need to evaluate each function at the given values of x.</span>
f(1) = 2(1) - 4 = -2
f(3.25) = 2(3.25) - 4 = 2.50
f(2.5) = 2(2.5) - 4 = 1
f(2) = 2(2) - 4 = 0

Similarly:
g(1) = <span>3⁻¹ + 1 = 1.33
g(3.25) = </span><span>3⁻³'²⁵ + 1 = 1.03
g(2.5) = </span>3⁻²'⁵ + 1 = 1.06
g(2) = 3⁻² + 1 = 1.11

Now, look for the value of x for which f(x) ≈ g(x): this happens for x = 2.5
Therefore the correct answer is c) x ≈ 2.5

–24 + 12d = 2(d – 3) + 22 what does e=
Kitty [74]

Answer:

d = 4

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

  • -24 + 12d = 2(d-3) + 22
  • -24 + 12d = (2)(d) + (2)(-3) + 22
  • -24 + 12d = 2d -6 + 22
  • 12d - 24 = 2d + 16

Step 2: Subtract 2d from both sides.

  • 12d - 24 - 2d = 2d + 16 - 2d
  • 10d - 24 = 16

Step 3: Add 24 to both sides.

  • 10d - 24 + 24 = 16 + 24
  • 10d = 40

Step 4: Divide both sides by 10.

  • \frac{10d}{10} = \frac{40}{10}
  • d = 4

Therefore, d = 4! I hope this helped you.

Oil leaked from a tank at a rate of r(t) liters per hour. the rate decreased as time passed, and values of the rate at two hour
Galina-37 [17]
The given data is
t, h:            0     2     4     6     8   10
r(t), L/h:   8.6  7.9  6.8  6.4  5.7  5.3

The lower and upper estimates for the total amount that leaked may be computed as the Left and Right Riemann sums.

The shape of the graph of r versus will determine which of the two sums yields an upper or lower sum.
The plot of the graph is shown below.

The Left Riemann sum is
Sl = 2*(8.6+7.9+6.8+6.4+5.7) = 70.8 L

The Right Riemann sum is
Sr = 2*(7.9+6.8+6.4+5.7+5.3) = 64.2 L

Answer:
The lower estimate for oil leakage is 64.2 L
The upper estimate for oil leakage is 70.8 L

A summary measure that is computed to describe a population characteristic from a sample is called a: A) statistic. B) census. C
Juliette [100K]

Answer:

A. Statistic

Step-by-step explanation:

Usually whole population is difficult to cover so the part of population is considered to assess the aspects of population. The statistic is the quantity which summarizes the sample. The problem illustrate that summary measure is calculated from sample to describe a population. As the summary measure is computed from sample then it is a statistic.
