(2y)^2-2.13yg+(13g)^2
(2y-13g)(2y-13g)
Answer:
Step-by-step explanation:
Since we are given a right triangle, we can use the trigonometric ratios.
- sin(θ)=opposite/hypotenuse
- cos(θ)= adjacent/hypotenuse
- tan(θ)=opposite/adjacent
We have the angle 24 and the sides 9 and x. 9 is the hypotenuse because it's opposite the right angle. x is the opposite, because it as across from the 24 degree angle. So, we have:
Therefore, we must use sine.
We are trying to solve for the value of x, so we must isolate the variable. x is being divided by 9. The inverse of division is multiplication. Multiply both sides by 9.
Round to the nearest tenth. The 6 in the hundredth place tells us to round the 6 to a 7.
x is approximately <u>3.7</u>
Answer:
B
Step-by-step explanation:
This is a quadratic in cosines
Factor by considering the factors of the product 2 × 1 = 2 which sum to give the coefficient of the cos x term (3 )
the factors are + 2 and + 1
use these factors to split the middle term
2cos²x + 2cosx + cosx + 1 = 0 (factor by grouping )
2cosx(cosx + 1) + 1(cosx + 1) = 0 (take out common factor (cosx + 1) )
(cosx + 1)(2cosx + 1) = 0
equate each factor to zero and solve for x
cosx + 1 = 0
cosx = - 1 ⇒ x = π
2cosx + 1 = 0
cosx = -
since cosx < 0 then x is in second/ third quadrant
x = or x =
Answer:
Step-by-step explanation:
Options a and d are right.
The given function is of the above form
We have here a=1/4 :b=1 : p = -pi/3: and k=-1
Hence we have an amplitude of 1/4, horizontal shift of pi/3 to the right,vertical shift of 1 unit down and vertical shrink of 1/4
Hence the correct choices would be
1) It has amplitude 1/4
d) Horizontal shift of pi/3 to the left
Other options are false
