Answer:
Its the bottom-right one
Step-by-step explanation:
Have a good day
Answer:
9.6
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
Plug in the knowns
a² + 22² = 24²
Subtract 22² from both sides
a² = 24² - 22²
a² = 576 - 484
a² = 92
Take the square root of both sides
a = 9.591663046625438
Rounded
a = 9.6 ft
Since pi is equivalent to 3.14 and means 180°, therefore 1.75 which
is about half of pi should be at almost 90°. The cos of a 90° angle which is located on
the y axis should be zero, therefore cos 1.75 must be near zero. However in
this case it is near one, clearly his calculator is in degree mode that is why
he got an erroneous answer.
What Sam
can do to get the correct answer would be to convert his calculator into radian
mode or convert the given 1.75 rad into degrees:
θ = 1.75
rad (180° / π rad)
θ =
100.2676
<span>cos 100.2676
= -0.1782 which is now correct since it
is nearer to zero</span>
Answer:
12 units
Step-by-step explanation:
The lactus rectum for a parabola is equal to 4 times the length of the focus from the vertex. Therefore, we need to determine the focus 
by using the equation 
for a vertical parabola.
We can deduce that 
, 
, and 
. Therefore, the focus of the parabola is 
or 
.
Because the focus is , then it is 3 units away from the vertex 
, making the length of the latus rectum 3*4=12 units.
