Answer:

9 units

Step-by-step explanation:

Distance, not difference. :)

Because these two points have the same x-coordinate, 0, the line segment connecting them is part of a vertical line. To find the disance between these points, we merely subtract the y-coordinates: 12 - 3 = 9.

That distance is 9 units.

When will the equation p(b)=520(0.88)^b have a value less than 100?

yulyashka [42]

Answer:

The given equation will have value less than 100 whenever the value of b is greater than 12.89

Step-by-step explanation:

For the given equation, p(b) = 520 × $0.88^{b}$ to have a value less than 100 we can establish inequality as:

p(b) < 100

or, 520 × $0.88^{b}$ < 100

or, $\frac{520}{520}$ × $0.88^{b}$ < $\frac{100}{520}$

or, $0.88^{b}$ < $\frac{1}{5.2}$

or, ㏒ ( $0.88^{b}$ ) < ㏒ ( $\frac{1}{5.2}$ )

or, b× ㏒ 0.88 < ㏒ ( $\frac{1}{5.2}$ )

or, $\frac{log (\frac{1}{5.2}) }{log (0.88)}$ < b

or, 12.89 < b

Hence for the equation to have value less than 100, b must be greater than 12.89.

Mazyrski [523]

4/5 acres of the land were sold.
40* 1/2 = 20
20* 3/5 = 12
12+20= 32
32/40 = 4/5 simplified

Nat2105 [25]

Answer:

$\frac{8}{45}$

Step-by-step explanation:

convert mixed number to improper fractions

3 $\frac{3}{4}$ = $\frac{15}{4}$

$\frac{\frac{2}{3} }{\frac{15}{4} }$

apply the fraction rule:

$\frac{2 * 4}{3 * 15}$

multiply the numbers

$\frac{8}{45}$
