Answer:
h = (10 ft)(4.01) = 40.1 ft
Step-by-step explanation:
The tangent function relates this elevation to the horizontal distance (10 ft) and the angle of elevation (76 degrees):
opp h
tan 76 degrees = --------- = ------------- = 4.01
adj 10 ft
Therefore , h = (10 ft)(4.01) = 40.1 ft
Answer:
C
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 4)² + (y - 3)² = 16 ← is in standard form → C
Answer:
9409
Step-by-step explanation:
Let's rewrite 97 as 100 - 3.
Identity used :
<u><em>(a - b)² = a² - 2ab + b²</em></u>
Now, evaluating the expression :
⇒ (100 - 3)²
⇒ (100)² - 2(100)(3) + (3)²
⇒ 10000 - 600 + 9
⇒ 9400 + 9
⇒ 9409
Step-by-step explanation:
