The measure of the acute angle is 60 degrees

Given the following trigonometry equation

tan x=2sinx

This can also be written as;

sinx/cosx=2sinx

Simplify to have:

1/cosx =2

2cosx = 1

cosx = 1/2

x = arccos(1/2)

x = 60 degrees

Hence the measure of the acute angle is 60 degrees

Step-by-step explanation:

Hypotenuse = 22

Since the two angles other than the 90° are both

45° , it means that the two legs of the right triangle are of equal length.

So, (x)²+ (x)² = 22²

2x² = 22²

x² = 484/2

x² = 242

x = √242

x = 15.55

Step-by-step explanation:

Each kilometer is 1000 meters so 1000 x 6 is 6000

The population in the year 2023 is 120,780.

The growth is linear hence, the equation of the growth is
y=ax+b where b represents the initial population and a is the number of people growing yearly.

So, according to the question statement, we have that

y=280x+b where x is the number of years past and y is the population in the xth year.

According to the given problem population in 2022 will be 120,500.

Suppose that the initial population is taken at 2000.

Hence, 120,500=280×(2022-2000)+b

⇒b=120,500-280×22

⇒b=120,500-6,160

    =114,340

So, the Linear equation becomes

y=280x+114,340

⇒y=280×(2023-2000)+114,340

⇒y=120,780

Hence, the population in the year 2023 is 120,780.

Step-by-step explanation/Answer:

PE(MD)(AS) (a good way to remember how to solve order of operations)

Start:

P: Parenthesis

E: Exponent

M: Multiplication & D: Division

A: Addition & S: Subtraction

:End

*Multiplication and Division are grouped together because they are on the same level, you decide which to do first depending on which comes first in the equation. The same applies for addition and subtraction.

So:

first thing we can look is the parenthesis, but before we can solve the whole thing we must notice the exponent only on the four. Since it is inside the parenthesis we must solve it first.

1. 4^2 = 16

now we will solve the addition inside the parenthesis

2. 16-13 = 3

now lets continue with pemdas, no more parenthesis so we tackle exponents

3. 5^2 = 25

Lets rewrite our equation with the changes we have made

8 × 3 ÷ 3 + 25 + 4 × 3

Now we solve multiplication and division

Equations is worked left to right, like english is read, so we will start on the left side and continue to the right, only solving multiplication and division.

4. 8 x 3 = 24

5. 24 ÷ 3 = 8

6. 4 x 3 = 12

new equation: 8 + 25 + 12

now we can use addition and subtraction (no subtraction luckily!)

7. 8 + 25 = 33

8. 33 + 12 = 45

Using the Pythagorean Theorem, it is found that the lot has an area of about 35 acres.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

Researching the problem on the internet, the lot has one leg of 800 feet and the hypotenuse is of 3900 feet, hence the other leg is found as follows:

[tex]800^2 + l^2 = 3900^2[/tex]

[tex]l = \sqrt{3900^2 - 800^2}[/tex]

l = 3817 feet.

The area of a right triangle is given by half the multiplication of it's legs. Hence, the area of the lot, in square feet, is given by:

A = 0.5 x 800 x 3817 = 1,526,800 square feet.

Each square feet is equivalent to 0.000029568 acres, hence the area in acres is given by:

Aa = 0.000029568 x 1,526,800 = 35 acres.

The best buy is (d) a 9 oz box of rice $1.25

The best buy is the product that has the least unit rate.

The unit rate is calculated as:

Unit = Price/Weight

So, we have:

Box 1:

Unit rate = $0.90/6 oz = $0.150 per oz

Box 2:

Unit rate = $1.93/12 oz = $0.161 per oz

Box 3:

Unit rate = $2.42/16 oz = $0.151 per oz

Box 4:

Unit rate = $1.25/9 oz = $0.139 per oz

The least unit price is $0.139 per oz for box 4

The expression for the distance from the 1st base to the 3rd base in terms of side length will be c=x√2

Given that the softball diamond is square in shape.

Let the side of the square i.e. distance between consecutive bases is x

The distance from the 1st base to the 3rd base creates the hypotenuse of a right triangle, where each side is equal to x i.e. x is the side length of the square formed by the baseball diamond.  

Using the Pythagorean theorem we have:

x² +x²= c²,

where c is the distance from the 1st base to the 3rd base.

Combining similar terms gives us

2x²=c²

Taking the square root of both sides we have

√2x²= √c²

⇒x√2=c

⇒c=x√2

This is the expression for the distance from the 1st base to the 3rd base in terms of side length.

Therefore the expression for the distance from the 1st base to the 3rd base in terms of side length will be c=x√2.

If a system of linear equations has exactly one solution then the slopes of both the lines should be different.

Given A system of linear equations has exactly one solution.

Linear equation is a type of equation  when when plotted on the graph gives a straight line. The slope is the ratio of the vertical change to the horizontal change between two distinct points on a line.

let two equations be who have one solution

2x+3y=7

5x+6y=1

solving them

x=7-3y/2

5(7-3y)/2+6y=1

35-15y/2+6y=1

35-15y+12y=2

-3y=-33

y=11

put the value of y in x=7-3y/2

x=7-3*11/2

x=7-33/2

x=-26/2

x=-13.

There is only one solution which is (-13,11)

Taking equations and convert them into standard form

y=1/6-5/6x

The standard form is y=a+bx where b is slope
