HELLP In this task, you will practice finding the area under a nonlinear function by using rectangles. You will use graphing ski

AfilCa [17]

Answer:

Part a. 1400 unit²

Part b 1240 unit²

Part c 1333.33 unit²

Step-by-step explanation:

The given function is 20·x - x²

Part a.

The dimensions of the five rectangles are;

20 × 20 + 20 × 18 + 20 × 16 + 20 × 10 + 20 × 6 = 1400 unit²

Part b.

The dimensions of the ten rectangles are;

10×20 + 10×18 + 10×16 + 10×16 + 10×14 + 10×12 + 10 × 10 + 10 × 8 + 10 × 6 + 10 ×4 = 1240 unit²

Part c.

To find the area with an infinite number of rectangles, we can use limits similar to integration;

$\int _{0}^{20}\left (20\cdot x - x^{2} \right )dx$

Which gives;

$\int _{0}^{20}\left (20\cdot x - x^{2} \right )dx = \left [\dfrac{20}{2}\cdot x^{2} - \dfrac{x^{3}}{3} \right ]_{0}^{20} = \left [10\cdot x^{2} - \dfrac{x^{3}}{3} \right ]_{0}^{20}$

10×20^2 - (20^3)/3 = 4000/3 = 1333.3333

The mass of a sewing needle is 0.585 gram.Round the mass to the nearest hundredth of a gram.

KIM [24]

ANSWER
The mass of the needle to the nearest hundredth of a gram is

$0.59grams$

EXPLANATION

The mass of the sewing needle is
$0.585grams$

We want to round the mass of this needle to the nearest hundredth.

This is the same as rounding to two decimal places.

When we count to the right after the decimal point, the second decimal place falls on the 8. Therefore the hundredth digit is 8.

The the next digit after 8 is 5, so we need to round up to get,

$0.585 \approx0.59 \: to \: the \: neearest \: hundredth$

How do you find the vertex and axis of symmetry for this function, <br><br> F(x)=3(x+1)^2

Andrews [41]

Answers:
Vertex is (-1,0)
Axis of symmetry is x = -1

============================================

Explanation:

F(x) = 3(x+1)^2
is the same as
y = 3(x-(-1))^2 + 0
which is in the form
y = a(x-h)^2 + k

We can see that
a = 3
h = -1
k = 0

Therefore the vertex is (h,k) = (-1,0)
The axis of symmetry is x = h = -1 which is the equation x = -1

The axis of symmetry in this case is a vertical line through the vertex.
