Answer:
We can think of this as a triangle rectangle.
We know that you eyes are 55ft above the ground, this can be one cathetus.
We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.
Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.
So we only know one angle and the opposite cathetus to this angle, then we can use the relation:
Sin(θ) = (opposite cathetus)/(hypotenuse)
Then if we use this equation, we will get:
Sin(50°) = 55ft/hypotenuse
hypotenuse = 55ft/sin(50°) = 71.8 ft
This means that the distance between you and the object is 71.8 ft.

A bakery sells oatmeal raisin cookies for $3 per bag. In the table below b
represents teh number of bags and c represents the cocst in dolloars.
Complete the function table using the rule c = 3b
Answer/Step-by-step explanation:
Number of bags = b
Cost in dollars = c
Unit price of raisin = $3
We have the function given as c = 3b.
To complete the table, substitute each value of b into c = 3b, to find the corresponding value of c.
✔️when b = 1,
c = 3(1)
c = 3
✔️when b = 2,
c = 3(2)
c = 6
✔️when b = 3,
c = 3(3)
c = 9
✔️when b = 4,
c = 3(4)
c = 12
Write the zero of the polynomial p(x) = 5x + 2.
Answer:
-2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
Answer:
the final answer is -2/5
Step-by-step explanation:
p(x) = 5x + 2
plug p(x) = 0
5x + 2 = 0
5x = - 2
x = - 2/5
then the final answer is -2/5

i s#ck at answering lma*oo. hope this helped
Caleb is correct the table doesn't have a constant rate of change so it can't be linear.
What is a nonlinear function?Any function whose graph is not a line is said to be nonlinear. It has the equation f(x) = ax + b. With the exception of form f(x) = ax + b, its equation can take any form. Any two points on the curve have the same slope. Every pair of points on the graph do not have the same slope.
The rate of change of the function is not constant for the given data so it can not be a linear function. It's an exponential function.
4/2 = 2; 8/4 = 2; 16/8 = 2.

write an equation for the line that passes through the points (-1,-12) and (4,8)
Answer:
y = 4x - 8
Step-by-step explanation:
(-1, -12) & (4, 8)
First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(8 - (-12)) / (4 - (-1))
Simplify the parentheses.
= (8 + 12) / (4 + 1)
= (20) / (5)
Simplify the fraction.
20/5
= 4
This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.
y = 4x + b
To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (4, 8). Plug in the x and y values into the x and y of the standard equation.
8 = 4(4) + b
To find b, multiply the slope and the input of x(4)
8 = 16 + b
Now, subtract 16 from both sides to isolate b.
-8 = b
Plug this into your standard equation.
y = 4x - 8
This is your equation.
Check this by plugging in the other point you have not checked yet (-1, -12).
y = 4x - 8
-12 = 4(-1) - 8
-12 = -4 - 8
- 12 = -12
Your equation is correct.
Hope this helps!

If AB=7x, CB=5x+8 and BD AC what is the length of CB
Answer:
x = 4
CB = 28
Step-by-step explanation:
In triangle ABC,
AB = CB..... (given)
Therefore,
7x = 5x + 8
7x - 5x = 8
2x = 8
x = 8/2
x = 4
CB = 5x + 8 = 5*4 + 8 = 20 + 8 = 28
how to find imaginary zeros anf real zeros of F(x)=-4x^5-8x^3+12x
Answer:
[tex]x=\{0, -1, 1, -i\sqrt{3}, i\sqrt{3}\}[/tex]
Step-by-step explanation:
We are given the function:
[tex]f(x)=-4x^5-8x^3+12x[/tex]
And we want to finds its zeros.
Therefore:
[tex]0=-4x^5-8x^3+12x[/tex]
Firstly, we can divide everything by -4:
[tex]0=x^5+2x^3-3x[/tex]
Factor out an x:
[tex]0=x(x^4+2x^2-3)[/tex]
This is in quadratic form. For simplicity, we can let:
[tex]u=x^2[/tex]
Then by substitution:
[tex]0=x(u^2+2u-3)[/tex]
Factor:
[tex]0=x(u+3)(u-1)[/tex]
Substitute back:
[tex]0=x(x^2+3)(x^2-1)[/tex]
By the Zero Product Property:
[tex]x=0\text{ and } x^2+3=0\text{ and } x^2-1=0[/tex]
Solving for each case:
[tex]x=0\text{ and } x=\pm\sqrt{-3}\text{ and } x=\pm\sqrt{1}[/tex]
Therefore, our real and complex zeros are:
[tex]x=\{0, -1, 1, -i\sqrt{3}, i\sqrt{3}\}[/tex]

Find the perimeter of quadrilateral LEAP with vertices L(-3, 1), E(3, 3), A(5, 7) and P(-1,5)
Answer:
4√5 + 4√10
Step-by-step explanation:
The perimeter is the sum of all the sides.
Using the coordinates given to us, we can find the sides of the quadrilateral.
d(ab) = √[(x2 - x1)² + (y2 - y1)²]
Given that, we apply that to each and every of the side, and thus we have
d(le) = √[(3 --3)² + (3 - 1)²]
d(le) = √[(6²) + (2)²]
d(le) = √(36 + 4)
d(le) = √40
d(ea) = √[(5 - 3)² + (7 - 3)²]
d(ea) = √[(2)² + (4²)]
d(ea) = √(4 + 16)
d(ea) = √20
d(ap) = √[(-1 - 5)² + (5 - 7)²]
d(ap) = √[-6)² + (-2)²]
d(ap) = √(36 + 4)
d(ap) = √40
d(pl) = √[(-1 --3)² + (5 - 1)²]
d(pl) = √[(-2)² + (4)²]
d(pl) = √(4 + 16)
d(pl) = √20
Perimeter of the quadrilateral is then
d(le) + d(ea) + d(ap) + d(pl)
√40 + √20 + √40 + √20
4√5 + 4√10
