Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
-2 is the slope of the line
Answer:
The amount of money Russel gets is $80
The amount of money Sara gets is $200
The amount of money Terry gets is $320
Step-by-step explanation:
Let
x -----> amount of money Russel gets
y -----> amount of money Sara gets
z -----> amount of money Terry gets
we know that
x/y=2/5 -----> x=(2/5)y ----> equation A
x/z=2/8 ----> x=(2/8)z ----> equation B
y/z=5/8 ----> y=(5/8)z ---> equation C
z=y+120 ----> equation D
Substitute equation D in equation C and solve for y
Multiply by 8 both sides to remove the fraction
Find the value of z
Find the value of x
therefore
The amount of money Russel gets is $80
The amount of money Sara gets is $200
The amount of money Terry gets is $320
A circle inside a semicircle is depicted in the diagram. The circle measures 10 cm in diameter. The semicircle has a 20 cm diameter. Calculate the shaded area. Give a precise response to the nearest decimal point.
The area of the shaded region is 39.3.
Given the diagram shows a circle inside a semicircle.
Every point in the plane of a circle, which is a closed, two-dimensional object, is evenly separated from the center. All lines that cross the circle join together to produce the line of reflection symmetry. Every angle also possesses rotational symmetry about its center.
Area of a circle = .
Semicircle is when a line travelling through the center of a circle reaches its two ends, a semicircle is created. Thus, a circle can be formed by combining two semicircles.
Area of a semicircle = .
The circle has a diameter of 10 cm. The semicircle has a diameter of 20 cm.
Semicircle:
Circle:
So,
Therefore, The area of the shaded region is 39.3.
