If Cody was 10 %, percent taller than he was on the first day of school last year then he was 150 cm tall on the first day of school last year.

 To find out the height of Cody on the first day of school last year, we need to perform a calculation as follows:

           Let's say their height of Cody on the first day of school last year is 'x'.

           His height of Cody on the first day of school this year is 165 cm.

           Cody is 10% taller than he was on the first day of school last year, so:

                      165 = x + (10% of x)

    Simplifying this equation will give

                        165 = x + 0.1 x 165

                               = 1.1xx

                               = 150

           Therefore, Cody was 150 cm tall on the first day of school last year.

Therefore, the area of triangle XYZ is 2 square units.

Area is a measure of the size of a two-dimensional shape or surface. It is defined as the amount of space inside the boundary of a flat or planar figure, such as a triangle, square, rectangle, or circle. The unit of area is typically square units, such as square meters (m²), square feet (ft²), or square centimeters (cm²).

Here,

To determine the area of triangle XYZ with coordinates (6,1), (2,5), and (10,9), we can use the formula for the area of a triangle:

Area = (1/2) * base * height

where the base is any side of the triangle and the height is the perpendicular distance from the base to the opposite vertex.

Distance between (6,1) and (2,5):

= √((6 - 2)² + (1 - 5)²)

= √(20)

So, the base of the triangle is √(20).

We can use the formula for the distance between a point and a line to do this:

Distance from (10,9) to line passing through (6,1) and (2,5):

= |(10 - 6)(5 - 1) - (2 - 6)(9 - 1)| / √((5 - 1)² + (6 - 2)²)

= 4 / √(20)

So, the height of the triangle is 4 / √(20).

Now, we can plug in the values for the base and height into the formula for the area of a triangle:

Area = (1/2) * base * height

= (1/2) * √(20) * (4 / √(20))

= 2

Step-by-step explanation:

Step-by-step explanation:

The y-axis is where x = 0 ....so the y-axis intercept occurs at x = o

 put  in   '0' for 'x'

y = 0^2 + 2(0) + 10       <===== 10 is the y-axis intercept

Answer:

We can use trigonometry to solve this problem. Let's call the distance from point A to the boat "x" and the distance from point B to the boat "y". Then we have:

In triangle AOC, tan(12) = OC / x

In triangle BOC, tan(64) = OC / y

We want to find the distance from point A to point B, which is the difference between x and y:

Distance AB = y - x

To solve for x and y, we need to eliminate OC. We can do this by setting the two expressions for OC equal to each other and solving for OC:

tan(12) = OC / x

OC = x tan(12)

tan(64) = OC / y

OC = y tan(64)

x tan(12) = y tan(64)

y = x tan(12) / tan(64)

Now we can substitute this expression for y into the equation for Distance AB:

Distance AB = y - x

Distance AB = x tan(12) / tan(64) - x

We can simplify this expression by factoring out an x:

Distance AB = x (tan(12) / tan(64) - 1)

Now we just need to plug in the values and calculate:

Distance AB = x (0.2174 - 1)

Distance AB = -0.7826 x

Since distance cannot be negative, we know that x > 0. Therefore, the boat is between point A and point B, and the distance from point A to point B is:

Distance AB = x (0.2174 - 1)

Distance AB = -0.7826 x

Distance AB ≈ 1.28 x

We don't know the actual value of x, but we can see that the distance from point A to point B is approximately 1.28 times the distance from point A to the boat when Jaxson measured the angle of depression to be 12 degrees.

After calculation, we know that the time taken by the lorry is 3 hours and 20 minutes.

Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.

Military time starts with 0000, also known as "zero hundred hours" or just "zero hundred," at the stroke of midnight.

Then, multiply each hour by one hundred, such that 1 a.m. is equal to 0100 (zero one hundred) hours, 2 a.m. is equal to 0200 (zero two hundred) hours, and so on.

So, we need to calculate the time as follows:

Leaving time = 14:55

Arriving time = 18:15

Then,

14:55 to 15:15 = 20 minutes

Then, 15:15 to 18:15 = 3 hours

The number of possible ways to select two vehicles = 55

Let m represents the number of cars and n represents the number of trucks.

An auto dealer has 5 different cars and 6 different trucks.

This means that m = 5 and n = 6

Finally, use the sum of interior angles equation again to find the measure of angle Y:
m∠Y = 180° - m∠X - m∠Z

Hello! To find the measure of each angle in triangle XYZ, we need to use the fact that the sum of the interior angles of a triangle is 180°. We are given that m∠X = (32x)° and m∠Z = (6.5x)°. Let's represent the measure of angle Y as m∠Y.

Now we can write an equation:

m∠X + m∠Y + m∠Z = 180°
(32x)° + m∠Y + (6.5x)° = 180°

We need to find the value of x and m∠Y. First, combine the x terms:

38.5x° + m∠Y = 180°

Now, we'll solve for x and then find m∠Y using the equation above. To find x, subtract m∠Y from both sides:

38.5x° = 180° - m∠Y

After finding the value of x, substitute it back into the expressions for m∠X and m∠Z to find the measures of angles X and Z.

The intercepted arcs of the inscribed angle are in proportion to the inscribed angle itself. In other words, the larger the inscribed angle, the more significant the intercepted arc it cuts, and vice versa. So, in an equilateral triangle, each of the inscribed angles of the circle measures 60°, which is half of the central angle of 120° that intercepts the same arc.

The angle measure and intercepted arcs of inscribed angles in an equilateral triangle inscribed in a circle are related, and the relationship between inscribed angles and central angles in a circle is that the inscribed angles are half of the central angle. Let us have a more in-depth understanding of these two angles.An inscribed angle is an angle that has its vertex on the circle and is formed by two chords that intersect at that point. It is half of the central angle that intercepts the same arc.A central angle is an angle whose vertex is at the center of the circle, and the sides of the angle pass through any two points on the circumference of the circle.

The given data is the altitude of a triangle is increasing at a rate of 3 centimeters/minute while the area of the triangle is increasing at a rate of 1 square centimeter/minute. then the rate of the base of the triangle changing when the altitude is 10 centimeters and the area is 94 square centimeters is calculated as,

  Area of a triangle = 1/2 * base * height

    The given area of the triangle is 94 square centimeters.

 Area of the triangle = 1/2 * base * altitude

 94 = 1/2 * b * 10b

(1)/(x)=(1)/(y)-(1)/(z) is an example of an equation that can be used to express z in terms of x and y. z can be expressed in terms of x and y as z= xy+1/y-x.

It is typically written using an equals sign “=” to show that the two expressions on either side of the equals sign are the same.

To solve the equation, it must first be rearranged so that z is on its own side of the equation.

This can be done by multiplying both sides of the equation by x and then subtracting (1)/(y) from both sides.

(1)/(x)=(1)/(y)-(1)/(z)

1-1/y= (x/y-x/z)-1/y

This yields the equation

y-1/y=(x/y-1/y)-(x/z+1/y)

y-1/y= (x-1/y)-(xy+1/zy)

(y-1/y)-(x-1/y)= (-xy)+1/zy

y-x/y= xy+1/zy

y-x=(xy+1)y/zy

Once the equation has been rearranged, the next step is to solve for z.

z= xy+1/y-x
