Answer 1

Answer:

Perimeter of ΔABC = 16.46 units

Step-by-step explanation:

By applying cosine rule (CAH) in the given triangle ADB,

cos(∠BAC) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

cos(55°) = [tex]\frac{3}{AB}[/tex]

AB = 5.23 units

Since, ΔABC is an isosceles triangle

AB = BC = 5.23 units

AD = DC = 3 units [Perpendicular drawn from a vertex of an isosceles triangle is a perpendicular bisector of the opposite side]

Therefore, AC = AD + DC = 6 units

Now perimeter of ΔABC = AB + BC + AC

= 5.23 + 5.23 + 6

= 16.46 units

Translate the sentence into an inequality. The sum of a number times 4 and 29 is at least 27. Use the variable y for the unknown number.

Answers

Answer:

y*4 + 29 >= 27

Step-by-step explanation:

A number times 4 is y*4 and the sum with 29 is y*4 + 29. If this is to be at least 27, it says that y*4 + 29 is greater than or equal to 27.

The population P of bacteria in a culture after t minutes is given by the equation p=p0 (1.14)^t where P0 is the initail population. If the number of the bacteria starts at 400, how long will it take for he population to incfrease to 2000

Answers

Answer:

The time taken is 4.79 minutes.

Step-by-step explanation:

[tex]P = Po(1.4)^{t}[/tex]

initial Population, Po = 400

Final population, P = 2000

Let the time is t.

[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

0 = pi/3 radians. Identify the terminal point and tan 0.

Answers

The terminal point is (0.5, 0.866), and the value of the tangent is 0.173.

How to identify the terminal point?

For any angle a, the coordinates of the terminal point are given by:

x = cos(a)

y = sin(a).

In this case, the angle is a = pi/3

Then the coordinates of the terminal point are:

x = cos(pi/3) = 0.5

y = sin(pi/3) = 0.866

So the terminal point is ( 0.5, 0.866)

And the tangent of that angle is equal to the quotient between the y-component and the x-component:

tan(pi/3) = 0.866/0.5 = 0.173

Find the length of the third side. If necessary, round to the nearest tenth.

Answers

Answer:

≈ 9.8

Step-by-step explanation:

Lets use the Pythagorean theorem.

a^2 + b^2 = c^2.

c is the hypotenuse or the longest side of a triangle.

a and b are the other 2 sides.

10^2 + b^2 = 14^2

10^2 + b^2 - 10^2 = 14^2 - 10^2

b^2 = 14^2 - 10^2

b^2 = 196 - 100

b^2 = 96

b ≈ 9.8

The length of the third side would be 9.8 units.

What is the right triangle?

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

The right triangle is given in the question, as shown.

According to Pythagoras' theorem,

In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

a² + b² = c²

Here c = 14 is the hypotenuse or the longest side of a triangle.

a = 10 and b are the other two sides.

10² + b² = 14²

10² + b² - 10² = 14² - 10²

b² = 14² - 10²

b² = 196 - 100

b² = 96

b ≈ 9.8

Thus, the length of the third side would be 9.8 units.
