Answer:
Step-by-step explanation:
we know that
The area of a triangle is equal to
------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of
so
the new dimensions of the triangle are
The new area of the triangle will be
------> equation B
Substitute equation A in equation B
Answer:
i can't seee the question is only the options i am seeing
Answer:
pretty sure its D. (200x^3)
hope this helps :) plz brainliest if wrong then don´t
Step-by-step explanation:
Answer: D. 44
Step-by-step explanation:
Here, we need to know the concept of trigonometry.
- Sine (sin) = Opposite/Hypotenuse = O/H
- Cosine (cos) = Adjacent/Hypotenuse = A/H
- Tangent (tan) = Oppostie/Adjacent = O/A
-----------------------------------------------------------------------------
Given
- The adjacent side of angle x and the hypotenuse.
- We are going to use Cosine.
<u>Solve</u>
cos (x) = 15/21
x = cos⁻¹ (15/21)
x ≈ 44
Hope this helps!! :)
Please let me know if you have any questions
2x^2 - 5x + 1 = 3
Subtract 3 from both sides
2x^2 - 5x + 1 - 3 = 3 - 3
2x^2 - 5x - 2 = 0
Use quadratic formula with A = 2, B = - 5, C = - 2
x = - b +- sqrt b^2 - 4ac/2a
x = - ( - 5) +- sqrt (- 5)^2 - 4(2)( - 2)/(2)(2)
x = 5 +- sqrt 41/4
x = 5/4 + 1/4sqrt 41 or x = 5/4 + - 1/4 sqrt 41
Answer: x = 5/4 + 1/4 sqrt 41
x = 5/4 + - 1/4 sqrt 41
Hope that helps!!!!! (D)
