Find the value of x in the triangle shown below.
x=
58°
6
6
20%
5.8
Answer:
x = 61°
Step-by-step explanation:
since the triangle has 2 congruent sides then it is isosceles with the 2 base angle being congruent, both x°
the sum of the 3 angles in the triangle = 180° , then
x + x + 58° = 180°
2x + 58° = 180° ( subtract 58° from both sides )
2x = 122° ( divide both sides by 2 )
x = 61°
Area of a rectangular playground in residential society is 2 2/5 km square and one of its sides is 1 2/5 km/ find the length of the other side
Step-by-step explanation:
area of a rectangle is
length × width
so, in our case
2 2/5 km² = 1 2/5 × width (or length, it does not matter)
12/5 km² = 7/5 × width
width = 12/5 / 7/5 = 12×5 / 7×5 = 12/7 = 1 5/7 km
The whooping crane is Canada’s tallest bird. When the angle of elevation of the sun
decreases from 30° to 25°, the length of a whooping crane’s shadow increases by 62 cm.
How tall is the whooping crane?
The crane is 139.8cm tall.
what is angle of elevation?The angle formed by the line of sight and the horizontal plane for an object above the horizontal.
Using Trigonometry
tan 30 = h/y
1/√3 = h/y
y= h√3
and, tan 25= h/y+62
0.96= h/(h√3 +62)
h= 0..96 (h√3 +62)
h= 0.96*h*1.732+0.96*62
h=0.796h +28.52
0.2404h= 28.52
h= 139.8 cm
Hence, whooping crane is 139.8 cm.

Which of the following is an asymptote of y=csc(x)?
x= -pi
x= -pi/3
x= pi/4
x= pi/2
Answer:
x = -π
Step-by-step explanation:
An asymptote line is a line that the graph does not intercept or pass through but rather approaches it. An asymptote line also is considered to be a line of undefined value of function because if an asymptote is x = a then f(a) is undefined.
The question gives a function y = csc(x) which is in another form, y = 1/sin(x).
We have to find the value of x that turns the function in undefined and that x-value will be your asymptote.
From a unit circle, we know that sin(-π) = -sin(π) = 0. Since sin(-π) = 0 —> y = csc(-π) = 1/sin(-π) = 1/0
Now we find out that at x = -π, csc(x) is not defined and hence, an asymptote is x = -π

A population of paramecia, P, can be modeled using the exponential
function P(t) 3(2), where t is the number of days since the
population was first observed. Which domain is most appropriate
=
to use to determine the population over the course of the first two
weeks?
The appropriate domain of the population function is 0 ≤ t ≤ 14
How to determine the domain?The function is given as:
P(t) = 3(2)^t
From the question, we understand that the maximum time is 2 weeks.
2 weeks in days is 14 days
This means that the function is valid for 14 days i.e. t = 0 to 14
Hence, the appropriate domain of the population function is 0 ≤ t ≤ 14

by factoring, identify the zeros of the quadratic function f (x) = x²-9x-22
Answer:
x= -2, x= +11
Step-by-step explanation:
I hope this is right!
To factorise, we need two numbers that add to make -9 and multiply together to make -22.
2 - 11 works, so we put it in the brackets in this order.
(x + 2) (x - 11)
so x + 2 = 0 and x - 11 =0
but we could also simplify this to say that x could be either -2 or + 11.

For what power of q is its value 1?
Answer:
0, for q ≠ 0 and q ≠ 1
Step-by-step explanation:
Assuming q ≠ 0, you want to find the value of x such that ...
q^x = 1
This is solved using logarithms.
__
x·log(q) = log(1) = 0
The zero product rule tells us this will have two solutions:
x = 0
log(q) = 0 ⇒ q = 1
If q is not 0 or 1, then its value is 1 when raised to the 0 power. If q is 1, then its value will be 1 when raised to any power.

To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
How to find the relationship between two equations?
System A equations:
-x - 2y = 7 ------ (1)
5x - 6y = -3 ------(2)
We multiply the first equation by 5, to get :
-5x - 10y = 35 -----(3)
The sum of equation (2) and equation (3) gives:
-16y = 32
y = 32/-16
y = -2
Thus, solution of system B is;
-x - 2(-2) = 7
-x + 4 = 7
x = -3
So, the solution of system B is (-3, -2), that means the solution of both systems are same.
