Solve 16(3x-5) -10(4x-8) = 40

Mashcka [7]

Answer:

x = 5

Step-by-step explanation:

Step 1: Multiply out the brackets

48x - 80 - 40x + 80 = 40 → negative + negative = positive [-10 x -8]

Step 2: Simplify

8x = 40 → collect like terms

Step 3: Solve

x = $\frac{40}{8}$

x = 5

Given: △PTC

Natalka [10]

Given the the two angles find the missing angle of P which is 30 degrees.

Since angle P and C are identical their sides are congruent.

The hypotenuse, the largest side is PC because it corresponds to angle T

Using Pythagorean Theorem
a^2 + b^2 = c^2

(PT)^2 + (CT)^2 = (PC)^2
Given that PT is 4 and knowing PT and CT are congruent we can rewrite this
(4)^2 + (4)^2 = (PC)^2
PC = rad(32)

A country's population in 1993 was 94 million. in 1999 in was 99 million. estimate the population in 2005 using the exponential

Jet001 [13]

The initial population is
P₀ = 94 million in 1993

The growth formula is
$P(t) = P_{0}e^{kt}$
where P(t) is the population (in millions) after t years, measured from 1993.
k = constant.

Because P(5) = 99 million (in 1999),
$94e^{5k} = 99 \\e^{5k}=1.0532 \\ 5k = ln(1.0532) \\ k = 0.010367$

In the year 2005, t = 12 years, and
$P(12)=94e^{0.010367*12} = 106.45$

Answer: 106 million (nearest million)

vector u is represented by the directed line segment RS and vector v is represented by the directed line segment OP. if R=(8,-2)

melamori03 [73]

The given points are

R=(8,-2) , S=(11,-6), O=(-3,-9), and P=(0,-13)

To find the value of u and v, we have to perform subtraction of the points . That is

$u= RS = =$
