The coordinates of that other point are: (5,5) . The x-coordinate gives us the distance of a point from the vertical axis, that is, the y-axis.

What is meant by  coordinates?

The x-coordinate gives us the distance of a point from the vertical axis, that is, the y-axis. Another name for the x-coordinate is abscissa. The y-coordinate indicates how far a point is from the x-axis, or the horizontal axis. The y-coordinate is also called the ordinate.

Notice that |x| means the absolute value of x. So, the function:

f(x) = IxI

takes x to the number with the same magnitude, but with a positive sign.

Thus,

f(-5) = I - 5I = 5

Therefore, the point (-5,5) is on the graph of f(x).

Now, we need to find another point with a y-value of 5.

Observe the graph of f(x):

Notice that another point with a y-value equal to 5 is (5, 5) because

f(5) = I5I = 5

Hence, the coordinates of that other point are: (5,5).

The complete question is : Tell whether the point (-5,5) is on the graph of f(x) = |x|. If it is, give the coordinates of another point with the same y-value.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

Table is shown in figure.

Two points on the table are (3, 0) and (4, 1).

Now,

Since, The equation of function passes through the points,

(3, 0) and (4, 1).

So, We need to find the slope of the function.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - 0) / (4 - 3)

m = 1

Thus, The equation of function with slope 1 is,

⇒ y - 0 = 1 (x - 3)

⇒ y = x - 3

⇒ y = x - 3

Thus, The equation of function notation for the relation will be,

⇒ y = x - 3

Answers

Answer:

FV= $1,545

Step-by-step explanation:

Giving the following information:

Elena deposits $1,500 in a savings account that earns 3.0% simple interest per year.

To calculate the nominal value of the account after one year, we need to use the following formula:

FV= (P*r*t) + P

FV= future value

P= principal

r= interest rate

t= 1

FV= (1,500*0.03*1) + 1,500

FV= $1,545

Explain your answer pls,thx

Answers

Answer:

14.83 meters

Step-by-step explanation:

Given that :

Angle of elevation (α) = 56°

Distance between observer and foot of tree = 10 meter.

Height of tree =?

Using trigonometry :

The height (h) of the tree can be obtained using :

Tan α = opposite / Adjacent

Tan(56°) = h / 10

1.4825609 = h / 10

Multiply both sides by 10

1.4825609 * 10 = h

14.8256 = h

Hence, the height of the tree is 14.83 m(2 decimal places).

C is the correct answer

The cross-sectional area of the shaft is 314 mm²

The outside diameter (d₂) = 6 cm = 60 mm

The inside diameter (d₁) = 4 cm = 40 mm

The cross sectional area of the shaft (A) is given by:

A = π(d₂ - d₁)²/4

Substituting values:

A = π(60 - 40)²/4

Simplifying the equation:

A = 314 mm²
