Answer:
Step-by-step explanation:
f(x)=4/5x^2+12x
For f(5)
: f(x) = 4/5(5)2 + 12(5)
= 4/5 × 25 + 60
= (4×5) + 60
= 20 + 60
= 80
Answer:
Part 1) The rate of change is
Part 2) The equation of the line into slope intercept form is
Part 3) Tom's salary would be in ten years
Step-by-step explanation:
Let
x ------> the number of years worked
y -----> Tom's salary amount in dollars
we have the points
A(1, 75,000) and B(4,81,000)
step 1
Find the rate of change (slope)
The slope is equal to
step 2
Find the equation of the line into slope-intercept form
we know that
where
m is the slope
b is the y-intercept
we have that
point A(1, 75,000)
substitute
The equation of the line is
step 3
What will Tom's salary be in ten years?
For x=10 years
Substitute in the linear equation

Answer:
Ganymede: A(sg) = 33.798.589 mil²
Earth´s moon: A(m) = 14.657.448 mil²
Ratio of surface areas : 2,31
Ratio of radio : 1,519
Step-by-step explanation:
We assume, ganymede and the moon both are spheres, according to tha the surface area of a sphere is:
A(s) = 4* π * r² r is radius in each case then we can calculte the surface area for ganymede A(sg) and moon A(m)
A(sg) = 4*3,1416 * (1640)²
A(sg) = 33.798.589 mil²
A(m) = 4*π* (1080)²
A(m) = 4 * 3,1416 * 1166400
A(m) = 14.657.448 mil²
Ratio of surface areas : 33798589/14657448
Ratio of surface areas : 2,31
Ratio of radio : 1640/1080
Ratio of radio : 1,519
