The graph of the function f(x) = –(x + 3)(x – 1) is shown below.

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

it is a downward parabola cutting x-axis at (-3,0),(1,0)

f(x)=-(x+3)(x-1)

=-(x²+2x-3)

=-(x²+2x+1-1-3)

=-(x+1)²+4

vertex is (-1,4)

A scale drawing of a square has a side length of 5 millimeters. The drawing has a scale of 1 mm : 5 km. Find the actual perimeter and area of the square.

Answers

Answer:

Actual Perimeter = 100 km

Actual Area = 625 km²

Step-by-step explanation:

A scale drawing of a square has a side length of 5 millimeters.

The drawing has a scale of 1 mm : 5 km (which represents 1 mm is equal to 5 km)

We need to find the actual measurement of 5 mm square on scale.

1 mm = 5 km

5 mm = 5 × 5 km

= 25 km

The actual length of the side of square is 25 km

Now, we find the perimeter and area of the square.

Perimeter of square = 4 × side

= 4 × 25

= 100 km

Area of the square = side × side

= 25 × 25

= 625 km²

Hence, The actual perimeter is 100 km and area of the square is 625 km²

How are the graphs of the functions y=2(2)^x and y=2(1.1)^x similar?

Answers

if the are equal then they can be similar, otherwise they are not.

Y=2(2)^x ----> y=(4)^x

Y=2(1•1)^x--> y=(2•2)^x----> y=(4)^x

The formula for the area of a circle. Then the correct option is A.

What is an irrational number?

If the value of a numerical expression is terminating then they are the rational number then they are called the rational number and if the value of a numerical expression is non-terminating then they are called an irrational number.

A. The formula for the area of a circle.

In the formula of circle, π is an irrational number, so the resulting area will be irrational.

B. The formula for the area of a trapezoid.

In the formula of trapezoid, all the value are rational number, so the resulting area will be rational.

C. The formula for the area of a triangle.

In the formula of triangle, all the value are rational number, so the resulting area will be rational.

D. The formula for the area of a rectangle.

In the formula of rectangle, all the value are rational number, so the resulting area will be rational.

Then the correct option is A.
