Step-by-step explanation:

In the first triangle, using Pythagorean's theorem, x^2+3^2=5^2, x = 4

In the second triangle, using Pythagorean's theorem, x^2+7^2=24^2, x = 25

In the third triangle, using Pythagorean's theorem, 8^2+15^2=x^2, x = 17

In the fourth triangle, using Pythagorean's theorem, x^2+8^2=10^2, x = 6

In the fifth triangle, using Pythagorean's theorem, 5^2+12^2=x^2, x = 13

Hey there!

“2 (5x + 3)”

• FIRST and ONLY STEP: DISTRIBUTE 2 to ALL OF YOUR NUMBERS in the parentheses

2(5x) + 2(3)

2(5x) = 10x ⬅️ FRONT number

2(3) = 6 ⬅️ BACK number

BOTH OF YOUR NUMBERS ARE POSITIVE SO WE DON’T HAVE TO CHANGE ANYTHING

Answer: 10x + 6 ☑️

Good luck on your assignment and enjoy your day!

Answer:

10x+6

Step-by-step explanation:

you have to multiply 2 times 5 then 2 times 3 then multiply 10 times x and write 6 beside it.

Answer:

1. 0, 2 π , π , 2 π/3 , 4 π/3

2. 7 π/6 , 11 π/6

Step-by-step explanation:

1. we want to find the value of theta

Let us represent theta by x for ease of documentation

So we have ;

sin 2x + sin x = 0

Mathematically;

sin 2x = 2sinxcosx

So;

2 sin x cos x + sin x = 0

sin x (2 cos x + 1) = 0

sin x = 0

or

2cos x + 1 = 0

x = arc sin (0)

within the given range;

x = theta = 0 , 2 π , π

For;

2 cos x + 1 = 0

2cos x = -1

cos x = -1/2

cos x = -0.5

x = arc cos (-0.5)

x = 2 π/3 , 4 π/3

2. cos 2 x = 1 + sin x

Mathematically;

cos 2 x = 1-2 sin^2x

let sin x = y

1-2y^2 = 1 + y

y = -2y^2

1 = -2y

y = -1/2

y = -0.5

sin x = y

sin x = -0.5

x = arc sin (-0.5)

x = 7 π/6 , 11 π/6

Answer:

y=-3(x)

Step-by-step explanation:

If x and y represent input and output respectively

y=-3(x)

Answer:

3 5/9

Step-by-step explanation:

You make 4/9 a whole by adding 5/9 and you get 9/9 or 1 whole

you add the whole to 5 and get 6, then add 3 because 6+3=9

I hope this helps!!!!

y-intercept b = 5

Answer:

x = 107

Step-by-step explanation:

The exterior angle and the interior angle make a supplementary angle.

This means it is 180°. Knowing this, we can solve for x:

73 + x = 180

x = 107

Therefore, x = 107.

3 batches of chocolate chip with 2 cups per batch is 6 cups total for the chocolate chip cookies.

Subtract the total needed for the chocolate chip from the total flour used, then divide the remaining amount by number of batches of oatmeal

Cookies.

The problem show 122 total cups, but I don’t think that is right... what is the actual total cups used?

Answer:

38 ft

Step-by-step explanation:

Answe

Step-by-step explanation:

Answer:

Step-by-step explanation:

1.

F=ma

89=68a

a=89/69 units/s²

2.F=ma

45=85 a

a=45/85=9/17 units/s²

Problem 1

Answer: Approximately 1.3 m/s^2

---------------

Work Shown:

We'll use the formula F = m*a, which is from Newton's second law.

The force applied is F = 89 newtons. The mass of the boulder is m = 69 kilograms. This means,

F = ma

89 = 69*a

a = 89/69

a = 1.28985507246377

a = 1.3

I rounded to 2 sig figs because the other given values (89 and 69) are to 2 sig figs as well.

=================================================

Problem 2

Answer: Approximately 0.53 m/s^2

---------------

Work Shown:

We'll follow the same idea as problem 1

This time we are given F = 45 and m = 85

So,

F = ma

45 = 85*a

85a = 45

a = 45/85

a = 0.52941176470589

a = 0.53

The acceleration is roughly 0.53 m/s^2, which means that for every second, the speed is increasing by roughly 0.53 m/s.

Answer:

9 = x

Step-by-step explanation:

63 = 7x (Given)

9 = x (Divide 7 on both sides)

Answer:

9

Step-by-step explanation:

63 divided by 7 = 9

X=9

Step-by-step explanation:

1 week = 7 days

Therefore 1 week = 60,000 letters

=> 7 days = 60,000 letters

=> 1 day = 60,000 / 7 = 8571.4... letters

Hence Obama receives around 8,571 letters per day.
