$\displaystyle\int_0^5R(t)\,\mathrm dt\approx\sum_{i=1}^4\frac{R(t_i)+R(t_{i-1})}2\Delta t_i$

where $t_0=0,t_1=1,t_2=2,t_3=4,t_4=5$ , and we define $\Delta t_i=t_i-t_{i-1}$ for $i\ge1$ . The sum is adding up the areas of several trapezoids, each with dimensions determined by the values of $t_i$ and $R(t_i)$ . (See the picture below)

So the number of deliveries made is approximately

$\displaystyle\frac{(250+100)(1-0)+(200+250)(2-1)+(350+200)(4-2)+(100+350)(5-4)}2=1175$

The triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral.

<h3>How to determine the existence of an isosceles triangle</h3>

In this question we must apply geometric properties of angles and triangles to determine that the triangle NET is an isosceles triangle. Isosceles triangles are triangles with two sides of equal length. In addition, we must apply the geometric concept of proportionality.

Now we proceed to prove the existence of the isosceles triangle:

BE ≅ SN Given
ET is the bisector of ∠BES Given
ET/ES = ET/EB Definition of proportionality
ES = EB (3)
ES ≅ EB Definition of congruence
ET ≅ TN SSS Theorem/Result

Therefore, the triangle NET is an isosceles triangle as ET ≅ TN and ET = TN < EN given the condition that BEST is a cyclic quadrilateral. $\blacksquare$

Step 1: Choose a point on the line, such as (2, 5).

The step of Talia that's incorrect is: C. step 3 because the slope ratio she calculated is incorrect.

<h3>What is the Slope?</h3>

The slope of a line (m) = rise/run = change in y / change in x.

Calculating the slope using two points on the line, (2, 5) and (1, 3), we should have:

Slope (m) = (5 - 3)/(2 - 1)

Slope (m) = (2)/(1)

Slope (m) = 2

This shows that the ratio of the slope calculated by Talia was wrong. The step that is incorrect is: C. Step 3

Artyom0805 [142]

Answer:

(12/1.35)^2 ~= 79.012346

(roughly equal to ~=)

Step-by-step explanation:

divide both sides by 1.35

12/1.35 = √x

square both sides to get rid of √

(12/1.35)^2 ~= 79.012346
