Answer:
f(-3)=56
Step-by-step explanation:
When evaluating a specific input for a function, you just plug that input in for x.
So in this case, f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(-3)^2-2(-3)+5
f(-3)=5(9)+6+5
f(-3)=45+6+5
f(-3)=56
-13x + 3 is decreasing and has a negative slope.
Answer:
523.33 in^3
Step-by-step explanation:
A sphere is a 3-dimensional version of a circle. An example of a sphere is a ball
Volume of a sphere = 
π
Where
π = 3.14
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
diameter = 2r
Radius = 10 in / 2 = 5 inches
× 3.14 ×
= 523.33 
Answer:
10 feet
Step-by-step explanation:
Given that the distance to be reached is 8 feet above ground and she she placed a ladder so that it reached the bottom of the window, the base of the ladder was 6 feet from the house, the length of the ladder considered with the other lengths forms a right angled triangle.
The length of the ladder represents the hypotenuse side hence using pythagoras theorem
F^2 = 8^2 + 6^2
where F is the length of the ladder in feet
F^2 = 64 + 36
= 100
find the root of both sides
F = 10 feet
The ladder is 10 feet long
