Answer:
x =
Step-by-step explanation:
(x + 6 )^2 = 49
get rid of the square , by square rooting the 49
x + 6 =
x = -6
x =
means + or - hence it could be -7 -6 = -1 ... or 7-6 = 1
therefore the answer is = or - 1
hence in terms of roots .. answer is :
Angles ∠ACD and ∠CAB are congruent because they are alternate angles. Then the area of the triangle AOB will be 22.53 square cm.
<h3>What is the area of the right-angle triangle?</h3>The area of the right-angle triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the right triangle.
We know that angles ∠ACD and ∠CAB are congruent because they are alternate angles.
α₁ = 40°
AO = OC = 7.8 cm
Then the area of the triangle will be
Area = 1/2 x 7.8 x 7.8 x tan40°
Area = 22.53 square cm

Answer:
d(1) = -3 and d(2)= -28
Step-by-step explanation:
Given that the distance d, in centimeters, that a diving board bends below its resting position when you stand at its end is dependent on your distance x, in meters, from the stabilized point
For finding out the distances for x=1 and x=2
let us substitute 1 and 2 for x
d(1) = -3 and d(2)= -28
