Find the equation of the line tangent to the function at the given point f(x)=5x^2 at x=10

Svet_ta [14]

f(x) = 5x²

f(10) = 5(10)² = 5(100) = 500

f'(x) = 10x

f'(10) = 10(10) = 100

Now, find the line that passes through (10, 500) and has a slope of 100

y - y₁ = m(x - x₁)

y - 500 = 100(x - 10)

y - 500 = 100x - 1000

y = 100x - 500

A cyclist travels 17 km from home to the park.

kupik [55]

Answer:

34 km/h

Step-by-step explanation:

speed = distance/time

Distance = 17km

Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours

speed = 17/0.5

speed = 34 km/h

What is the volume of a cylinder, in cubic centimeters, with a height of 7 centimeters

devlian [24]

Answer:

The volume of a cylinder is $1782\ cm^3$ .

Step-by-step explanation:

We have,

Height of cylinder, h = 7 cm

Diameter of cylinder, d = 18 cm

Radius, r = 9 cm

It is required to find volume of cylinder. The formula of the volume of cylinder is given by :

$V=\pi r^2h\\\\V=\dfrac{22}{7}\times (9)^2\times 7\\\\V=1782\ cm^3$

So, the volume of a cylinder is $1782\ cm^3$ .
