Angle 3 is a vertical angle of angle 1 and will always be identical to what angle 1 is.

Angle 2 and angle 4 are supplementary angles to angle 1 and will always be the difference between 180 and what angle 1 is.

For example if angle 1 was 45 degrees, angle 3 would also be 45 degrees and angle 2 and angle 4 would be 180-45 = 135 degrees.

Answer:

PC = 12 , AP = 10

Step-by-step explanation:

For each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, then

(1)

PC = 2 × PF = 2 × 6 = 12

(2)

AP = [tex]\frac{2}{3}[/tex] × AD = [tex]\frac{2}{3}[/tex] × 15 = 2 × 5 = 10

Answer:

The answer is 20 meters squared

base area = side^2 = 2^2 = 4 m^2

base perimeter = (2 x 4) = 8 m

lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2

surface area = (base area + lateral surface) = (4 + 16)= 20m^2

Answer:

20m^2

Step-by-step explanation:

base area = side^2 = 2^2 = 4 m^2

base perimeter = 2 x 4 = 8 m

lateral surface = (base perimeter x slant height)/2 = (8 x 4)/2 = 16 m^2

surface area = base area + lateral surface = 4 + 16= 20m^2

Answer:

option 3)

14% approx

Step-by-step explanation:

Given data

Initial= $18.00

final =$20.50

% increase= final - initial/initia *100

% increase= 20.50-18.0/18*100

% increase=2.5/18*100

% increase=0.138*100

% increase=13.8%

Hence the increase is 13.8%

=14% approx

Answer:

x = 14

Step-by-step explanation:

Hi,

To begin, distribute the 2 to the x and -9.

So...

2 ( x - 9 ) = 10

2x - 18 = 10

2x = 28

x = 14

Answer:

0.125

Step-by-step explanation:

For a fair coin, H and T is the same probability. To get zero tails, we need to toss a head, then a head, and again a head - each time we succeed with probability of 0.5, so succeeding 3 times happens 0.5^3 of the time = 0.125

Alternatively, look at all the options:

HHH

HHT

HTH

HTT

THH

THT

TTH

TTT

Only one option has no tails, and because the coin is fair, each option is equally probable, so the probability of HHH is 1/8 = 0.125

if the 20% of a number is 386, what will be 30% of the same number

Answer will be 157

If 20% of a number is 386,  30% of the same number is 579

Let the number be x.

So,we have:

20% * x = 386

Express 20% as 0.20

0.20 * x = 386

Divide both sides by 0.20

x = 1930

30% of the number is represented as:

30% * 1930

Evaluate the product

30% * 1930 = 579

Hence, 30% of the same number is 579

Step-by-step explanation:

b > 1 is growth. decay would be less than 1

The exponential growth the term b>1

But sometimes things can grow (or the opposite: decay) exponentially, at least for a while.

So we have a generally useful formula:

y(t) = a × ekt

Where y(t) = value at time "t"

a = value at the start

k = rate of growth (when >0) or decay (when <0)

t = time

for example,

Example: 2 months ago you had 3 mice, you now have 18. What is the "k" value? How many mice 2 Months from now? How many mice 1 Year from now?

Start with the formula:

y(t) = a × ekt

We know a=3 mice, t=2 months, and right now y(2)=18 mice:

18 = 3 × e2k

Now some algebra to solve for k:

Divide both sides by 3: 6 = e2k

Take the natural logarithm of both sides: ln(6) = ln(e2k)

ln(ex)=x, so: ln(6) = 2k

Swap sides: 2k = ln(6)

Divide by 2: k = ln(6)/2

Notes:

The step where we used ln(ex)=x is explained at Exponents and Logarithms.

we could calculate k ≈ 0.896, but it is best to keep it as k = ln(6)/2 until we do our final calculations.

We can now put k = ln(6)/2 into our formula from before:

y(t) = 3 e(ln(6)/2)t

Now let's calculate the population in 2 more months (at t=4 months):

y(4) = 3 e(ln(6)/2)×4 = 108

And in 1 year from now (t=14 months):

y(14) = 3 e(ln(6)/2)×14 = 839,808

As, per the formula for exponential growth the factor b will tells whether there is exponential growth or decay.

so, when b>1 then it is exponential growth and b<1 shows decays.

Answer:

√(3)/3

Step-by-step explanation:

cos(A) = adj./hyp.

adj. = √(3) or √(3)/2

hyp. = 2 or 1

use unit circle:

hyp. = 1

adj. = √(3)/2

use pythagorean theorem c² - b² = a²

1² - (√(3)/2)² = 1 - 0.75 = 0.25

a² = 0.25

a = √(0.25)

a = 0.5

tan(A) = opp./adj.

tan(A) = 0.5/(√(3)/2)

tan(A) = 1/√(3)

rationalize

tan(A) = √(3)/3
