Answer:
49n² - 70n + 25
Step-by-step explanation:
Area of a square = s²
Where,
s = side length = 7n - 5
Area of the square = (7n - 5)²
= (7n - 5)(7n - 5)
= 7n(7n - 5) -5(7n - 5)
= 49n² - 35n - 35n + 25 (distributive property of equality)
Add like terms
Area = 49n² - 70n + 25
So,
To round the nearest thousand, look at the number in the hundredths place.
If n ≥ 5, round up
If n < 5, round down
4 < 5, therefore round down.
389,422 --> 389,000
Answer:
37.3
Step-by-step explanation:
19tan(63) = x = 37.289... = 37.3
These are the y intercepts
1. (0, 1/3)
2. (0, 26/3)
Answer:
The value of
.
Step-by-step explanation:
Diagram of the given scenario shown below.
Given that,
Distance from bench to Jasmyn is
.
Distance from bench to Willard is
.
From the Question,
The given wishing well is a circle and all the distance are tangent to the circle.
So, Triangle formed by these points are such as Δ
and Δ
.
Now, taking both Δ
and Δ
.
⇒
{Radius of circle are equal}
⇒
{Common side}
⇒ ∠
∠
{radius is always perpendicular
to the point of tangent }
∴ Δ
≅ Δ
{By SAS congruence theorem}
Therefore,
....(1) {corresponding part of
congruence triangle (CPCT)}
Thus,
⇒
{from equation (1)}
⇒
⇒ 
Hence, The value of
.
