Answer:
59.04°
Step-by-step explanation:
Elise is standing on top of a 50 foot building and sees her friend, Molly. If Molly is 30 feet away from the base of the building, what is the angle of depression from Elise to Molly? Elise's eye height is 4.5 feet.
We solve using the Trigonometric function of Tangent
tan x = Opposite/ Adjacent
tan x= 50 ft/30ft
x = arc tan (50 ft/30 ft)
x = 59.036243468°
Approximately = 59.04°

Answer:
D. 225 square units
Step-by-step explanation:
Multiply 2.5 by the scale factor of 6.
2.5 * 6 = 15
Then because it is a square, multiply 15*15
15 * 15 = 225
The answer is 225
Answer:
D
Step-by-step explanation:
The side length of the new square = 6 × 2.5 = 15 then its area
A = 15² = 225 units² → D

Algebra 1 need help (Solving exponents equations)
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the exponents and indices.
here, we should remember one thing that,
3 ^3 = 27 and 1/3^x = 3^-x
so we get as,
(3^-3)^4-x = (3^3)^2x-1
==> 3^-12+3x = 3^6x-3
since the base is same that is 3 , we equate their powers.
-12x+3=6x-3
==> 3+3 = 6x+12x
==> 6 = 18x
hence ===> x = 6/18 = 1/3
hence, x = 1/3
The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I will mark brainliest!
Answer:
Option 4Step-by-step explanation:
Midpoint of the diameter is the center.
Use midpoint formula to determine the coordinates:
x = (2 - 4)/2 = -1y = (5 + 13)/2 = 9Find the radius using the midpoint and one of the endpoints and the distance formula:
r = [tex]\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5[/tex]Use the equation of the circle:
(x - (-1))² + (y - 9)² = 5²(x + 1)² + (y - 9)² = 25Correct choice is 4

Which expressions are equivalent to 35+30s-45t?
Answer:
B and C
Step-by-step explanation:
5 * (7 + 6s - 9t) = 7*5 + 6s *5 - 9t*5
= 35 + 30s - 45t
(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)
= 35 + 30s - 45t
The perimeter of a triangle is 26 feet. The second side is twice as long as the first. the third side is 1 foot longer than the second side. What is the length of the 3 sides?
Answer:
5, 10 and 11 feet.
Step-by-step explanation:
Let length of first side be x feet then
second side = 2x feet
third side = 2x + 1 feet.
So we have the equation:
x + 2x + 2x + 1 = 26
5x + 1 = 26
5x = 25
x = 5 feet.
So first side = = 5 feet, second = 10 and third = 11 feet.
Select the quadratic equation that has no real solutions. 25x-10x+4=0
Answer:
Step-by-step explanation:
Were there not several equations from which to choose?
The coefficients of 25x^2 - 10x + 4 are {25, -10, 4}. The discriminant is thus b^2 - 4ac, or (-10)^2 - 4(25)(4), or 100 - 400, or -300. Because the discriminant is negative, the quadratic has no real solutions.
The quadratic equation with no real solution is 25x²-10x+4 = 0
What is a quadratic equation?The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given that, which of the equations have no real solution,
Considering the quadratic equation 25x²-10x+4 = 0
D = [tex]\sqrt{b^{2} -4ac}[/tex]
We know, when √D > 0, real roots
√D = 0, equal roots
√D < 0, imaginary roots
[tex]\sqrt{b^{2} -4ac}[/tex] =
[tex]\sqrt{10^{2} -400} \\\sqrt{-300}[/tex]
Since, the discriminant is less than 0, therefore, its roots are imaginary.
Hence, The quadratic equation with no real solution is 25x²-10x+4 = 0

how many ounces are in 6 1/4 pounds(show your work)
Answer:
100 oz
Step-by-step explanation:
to find out how many ounces in a quarter pound, multiply 16 by ... 1/8 lb = 2 oz; 1/4 lb = 4 oz; 1/3 lb = 5.33 oz; 1/2 lb = 8 oz; 1 lb = 16 oz; 1.5 lb
Answer:
100 ounces
Step-by-step explanation:
there are 16 oz in a pound, so, 6 x 16 = 96 oz. And in 1/4 lbs there are 4 oz, so, when you add that to 96, it equals 100 oz.

Please Help!!! Identify two equations from above that represent parallel lines and explain why you choose them
Identify two equations from above that represent perpendicular lines and explain why you choose them
Answer:
parallel : (b) and (g)
perpendicular : (d) and (f)
Step-by-step explanation:
straight line equation : y = mx + c
Lines that are parallel have the the same gradient(m),
(b) and (g) are parallel, both of them has m= 1/2
Lines that are perpendicular will have the product of their
gradient(m) equal to -1. So, m1 × m2 = -1
(d) and (f) are perpendicular, because : -4 × ¼ = -1

The triangle is a right triangle, as denoted by the red square at the bottom, we can use the Pythagorean Theorem to figure out the second side (since we are given the other side and the hypotenuse).
a² + b² = c²
(8)² + b² = (10)²
64 + b² = 100

b = ±[tex]\sqrt{36}[/tex]
b = ± 6
But we know that distance is always positive, so
b = 6

How many solutions does the equation 2(x+1) = 2x+1 have?
Answer:
No SolutionsExplanation:
2(x + 1) = 2x + 1
Simplify both sides of the equation2(x + 1) = 2x + 1
(2)(x) + (2)(1) = 2x + 1 [Distribute]
2x + 2 = 2x + 1Subtract 2x from both sides2x + 2 − 2x = 2x + 1 − 2x
2 = 1
Subtract 2 from both sides2 − 2 = 1 − 2

Go step by step to reduce the radical.
Answer:
Step-by-step explanation:
You can begin by breaking down √(160) into its prime factors.
160 = 2 * 2 * 2 * 2 * 2 * 5
√(160) = √(2 * 2 * 2 * 2 *2 * 5)
This can be broken down further by
2 * 2√2 * 5
For every 2 factors that are the same, take one outside the brackets
4 √10
I suppose the way you are supposed to write this is √16 * √10
I'm not sure I'm right. There are 2 square root signs there and it is the only way I can think of to use 2 square root signs.
