Answer:

B, if you arent sure you could always plug the answer choices in for X

Step-by-step explanation:

2x-4x= -2

-2+6 =4

4(2)

8-6 =2

2(2) = 4 - 2= 2

Let AB be the line segment beginning at point A(0, 3) and ending at point B(6, -10). Find the point P on the line segment that i

Softa [21]

Answer:

Point P = 14.32

Step-by-step explanation:

Point P represents the distance from point A to point B.

The formula is given as:

$P=\sqrt{(x_{2}-x_{1}) ^{2} + (y_{2}-y_{1}) ^{2}}$

x1 = 0, y1 = 3, x2 = 6, and y2 = -10

$P=\sqrt{(6-0) ^{2} + (-10-3) ^{2}}\sqrt{x} \\\\P = \sqrt{6^{2} + (-13)^{2} }= \sqrt{36+169} \\\\P = \sqrt{205}\\ \\P = 14.3178$

P ≅ 14.32

James drove up 6,400 feet to a camp area on a mountain to meet his friends. They walked a trail that led to the mountain summit

gregori [183]

The answer is 4900 because you add the 6,400+1,800=8,200 then you subtract the 8,200-3,300= 4,900

Answer: a = 4, b = 163,422

Step-by-step explanation:

$P = P_{0} e^{kt}$ P is the new population, P₀ is the initial population, k is the growth rate, t is the time elapsed.

Part a) What do we know?

P = 7003

P₀ = unknown

k = .21 (converted 21% into a decimal)

t = 36 yrs (2006 - 1970)

$P = P_{0} e^{kt}$ need to solve for P₀

$7003 = P_{0} e^{(.21)(36)}$

$7003 = P_{0} e^{7.56}$

7003 = P₀ (1920)

$\frac{7003}{1920} = P_{0}$

3.6 = P₀

rounded to the nearest whole number = 4

Part b) What do we know?

P = unknown

P₀ = 7003

k = .21 (converted 21% into a decimal)

t = 15 yrs (2021 - 2006)

$P = P_{0} e^{kt}$ need to solve for P₀

$P = 7003 e^{(.21)(15)}$

$P = 7003 e^{3.15}$

P = 7003(23.33)

P = 163,422.46

rounded to the nearest whole number = 163,422

*************************************************************

Answer: 2, -1

Step-by-step explanation:

eˣ² = eˣ * e²

eˣ² = eˣ⁺²

x² = x + 2

x² - x - 2 = 0

(x - 2)(x + 1) = 0

x - 2 = 0 or x + 1 = 0

x = 2 or x = -1

Check both answer for validity:

eˣ² = eˣ⁺²

e⁴ = e⁴ or e¹ = e¹

TRUE TRUE

*****************************************

Answer: 0 = ln 1

Step-by-step explanation:

$e^{-10} = \frac{1}{e^{10}}$

$ln(e^{-10}) = ln(\frac{1}{e^{10}})$

-10 = ln 1 - 10 log rules say division is subtraction

0 = ln 1
