Answer:
32 m
Step-by-step explanation:
<u>Trigonometric ratios</u>
where:
- is the angle
- O is the side opposite the angle
- A is the side adjacent the angle
- H is the hypotenuse (the side opposite the right angle)
Calculate the height of the radio mast using the tan trig ratio.
Given:
- = 30°
- O = h (height of radio mast)
- A = 96 m
To calculate the distance from the second point to the base of the mast, use the tan trig ratio:
Given:
- = 60°
- O = 32√3 m
- A = d
She is starting at 4000, so that is the y-intercept of the graph. She is descending at 40 feet per minute, so her rate of change or slope is -40. The graph would look like this:
Answer:
c. x ≈ 1.71, y ≈ 6.29, z ≈ 60.71
Step-by-step explanation:
You are at a bit of a disadvantage with this problem, because both the hint and the answer choices are incorrect.
The matrix equation is ...
Contrary to what the hint is telling you, the multiplication by the inverse must be on the left:
Using appropriate tools to compute the inverse, this becomes ...
The closest match is choice C.
There is not GCF here, yo can put 1.
Answer:
x= -1 and y =7
Step-by-step explanation:
To solve by elimination, multiply the entire first equation by 2 so that your x terms have the same coefficients.
2*(9x+2y=5) becomes 18x+4y=10.
Now stack and add each like term.
18x+4y=10
-18x-3y=-3
----------------------
0x +y = 7
y=7
Substitute y=7 into one of the original equations and solve for x.
9x +2(7) = 5
9x + 14 = 5
9x = -9
x=-1
