Answer:
33.05°
Step-by-step explanation:
The diagram above is a right angled triangle.
To solve for this question, we would be making use of the trigonometric function of Sine
sin θ = Opposite side/Hypotenuse
From the above diagram,
Opposite side = 162.5 yards
Hypotenuse = 298 yards
θ = unknown
sin θ = 162.5 yards/298 yards
sin θ = 0.5453020134
θ = arc sin(0.5453020134)
θ = 33.045304587°
Approximately
θ = 33.05°

Answer:
(i) F = 25 N
(ii) F = 35.36 N
(iii) F = 43.3 N
Step-by-step explanation:
We note that the component of force acting along the incline surface is given by the relation
Force, acting parallel to the incline plane, [tex]F_p[/tex] = M×g×sin(θ)
Given that the weight of the body is given as 50 N, we have;
M×g = 50 N
Therefore we have;
(i) For the plane with angle of elevation = 30°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(30°) = 25 N
The force [tex]F_p[/tex] = F = 25 N
F = 25 N
(ii) For the plane with angle of elevation = 45°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(45°) = 50 × (√2)/2 = 25·√2 N
[tex]F_p[/tex] = F = 25×√2 N = 35.36 N
F = 35.36 N
(iii) For the plane with angle of elevation = 60°
[tex]F_p[/tex] = M×g×sin(θ) = 50 × sin(60°) = 50 × (√3)/2 = 25·√3 N
[tex]F_p[/tex] = F = 25×√3 N = 43.3 N
F = 43.3 N.
Sally begins hiking at an elevation of 224 feet. Then, she descends 131 feet
and climbs 67 feet higher than her current position. She then descends
163 feet. Write an addition sentence to describe the situation. Then determine
and interpret the sum.
Answer:
-3 feets
Step-by-step explanation:
Given the following :
Starting point = 224 feets
Then descends 131 feets
Then climbs 67 feets higher than her current position
Then descends 163 feets
Addition sentence to describe the situation :
224feets + (-131)feets + 67feets + (-163)feets
Negative (-) points represents descent
224feets - 131feets + 67feets - 163feets = - 3feets
This means Sally is - 3 feets below her initial position.
What is the y-intercept of the polynomial f(x)f(x) f(x) defined below? Write the y-value only. f(x)=−4x2+x5+10x3+5x+8x4f(x)=-4x^2+x^5+10x^3+5x+8x^4 f(x)=−4x 2 +x 5 +10x 3 +5x+8x 4
Answer:
y = 0
Step-by-step explanation:
Given
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴
Required
Determine the y intercept
The y intercept of a function is a point where x = 0
So, we have to substitute 0 for x in the above function
f(x) = 4x² +x⁵ +10x³ +5x+8x⁴ becomes
f(0) = 4(0)² +(0)⁵ +10(0)³ +5(0)+8(0)⁴
f(0) = 4 * 0 + 0 + 10 * 0 + 5 * 0 + 8 * 0
f(0) = 0 + 0 + 0 + 0 + 0
f(0) = 0
Substitute y for f(0)
y = 0
Hence, the y intercept is 0
a carpenter works one third as long after lunch as he worked before lunch if he worked 8 hours total how long did he work before lunch
Answer:
6 hours before lunch
Step-by-step explanation:
Let x = hours before lunch
after lunch = 1/3x
Total time worked = 8 hours
x+1/3 x = 8
Combine like terms
4/3x = 8
Multiply each side by 3/4
3/4 * 4/3x = 8 * 3/4
x = 6
6 hours before lunch
Answer:
The carpenter worked 3x, or 6 hrs, before lunch.
Step-by-step explanation:
Represent the time worked before lunch as 3x and the time worked after lunch as x. Then 3x + x = 8 hrs, and so:
4x = 8 hrs, and
x = 2 hrs
The carpenter worked 3x, or 6 hrs, before lunch.

==============================================
Explanation:
The chords intersect to form the angle 73 degrees. The chords also form the arcs of 96 and x. Averaging the arc measures will result in the internal angle 73
---------
(x+96)/2 = 73
x+96 = 2*73 ... multiply both sides by 2
x+96 = 146
x = 146-96 ... subtract 96 from both sides
x = 50
Find the slope and then write the slope as a simplified fraction
A) (-6,3) (9,7)
B)(4,-10)(-2,-6)
Answer:
slope: (y² - y¹) / (x² - x¹)
(-6, 3) (9, 7)
(7 - 3) / (9 + 6) = 4 / 15
y = 4/15x + b
slope: (4/15)x
(4, -10) (-2, -6)
(-6 + 10) / (-2 - 4) = 4 / -6 = 2 / -3
y = (-2/3)x + b
slope: (-2/3)x
289 and y more is 206
Answer:
Equation translates to 289 + y = 206
it solves to y = -83
====================================================
Explanation:
The "and y more" means we are adding y onto 289 to get the expression 289+y. This is set equal to 206 because of the term "is" in the original statement.
Therefore, "289 and y more is 206" translates fully to the equation 289+y = 206
This is the same as saying y+289 = 206
To isolate y, we undo what is happening to it. We are adding 289 to it, so we must subtract 289 from both sides
y+289 = 206
y+289-289 = 206-289
y = -83
So we are adding -83 to 289 to get 206

What’s the answer
Answer:
112.5:15=7.5
Step-by-step explanation:
112.5:15
=112.5÷15
=7.5
The equation "112.5 : 15 = 7.5" is true.
Proceed option 1:
"15 - 112.5 = 7.5":
This equation is not correct because 15 - 112.5 does not equal 7.5.
Proceed option 2:
"15 : 112.5 = 75":
This equation is not correct because when we divide 15 by 112.5, we get a decimal answer of 0.1333, not 75.
Proceed option 3:
"112.5 : 15 = 7.5": This equation is correct.
When we divide 112.5 by 15, we get an answer of 7.5.
Proceed option 4:
"112.5 : 15 = 75": This equation is not correct because when we divide 112.5 by 15, we get an answer of 7.5, not 75.
Hence equation "112.5 : 15 = 7.5" is correct.

Imagine that you stop at a nearby coffee chain and purchase a $5 coffee every morning on your way to work. You do this 5 days a week for 50 weeks out of the year. While it may seem like a small expense each day, this habit can add up and affect your personal finances. How much would this habit cost you over the next five years
Answer:
$6250
Step-by-step explanation:
Hello!
First, we find out how much you spend a week.
Since you buy a $5 coffee 5 days a week we multiply the price for a coffee by 5.
5 * 5 = 25.
Next, we find out how much you spend a year.
Since you do it 50 weeks a year we multiply the amount you spend a week by 50
25 * 50 = 1250
Then, we find out how much you spend in 5 years.
We multiply the cost a year by the amount of years
1250 * 5 = 6250
The answer is $6250

Help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
x ≥ −5 and x < 4
Step-by-step explanation:
-4x + 1 ≤ 21 and 5x + 2 < 22
5x + 2 < 22 = x < 4
We can plug it in: 5 x 3 + 2 < 22 = 17 < 22
-4x + 1 ≤ 21 = x= -5 and lower
Plug it in: -4 x -5 + 1 ≤ 21 = 21 ≤ 21 = x ≥−5
So both answers would be:
x ≥−5 for -4x + 1 ≥ 21
x < 4 for 5x + 2 < 22
Given xy = 4 and x2 + y2 = a, which expression is equal to (x + y)2?
a + 6
a + 8
a + 4
Answer:
a + 8
Step-by-step explanation:
Note that
(x + y)² = x² + 2xy + y²
= x² + y² + 2xy
= a + 2(4) = a + 8
Here, we are required to determine an expression equal to (x + y)²
The correct answer is therefore (a + 8)
First, x² + y² = a can be rewritten completing the square method as;
(x+y) (x+y) = a + 2xy
when we expand the expression above; we have;
x² + 2xy + y² = a + 2xy
since, 2xy is present on both sides of the equation;
we still get the expression; x² + y² = a
Therefore, (x+y)² = a + 2xy
we can then substitute the value 4 for xy in the equation above;
Thus, since xy = 4, therefore 2xy = 8
Consequently, (x+y)² = a + 8
The correct answer is therefore (a + 8)

What is the equation of the quadratic function represented by this graph
Answer:
f(x) = - x² + 2x + 8or f(x) = - (x - 1)² + 9 or f(x) = - (x + 2)(x - 4)Step-by-step explanation:
f(0) = 8 {y-axis intercept = (0, 8)}
Vertex = (1, 9)
f(x) = a(x - 1)² + 9
8 = a(0-1)² + 9
8 = a + 9
a = -1
f(x) = - (x - 1)² + 9
f(x) = - (x² - 2x + 1) + 9
f(x) = - x² + 2x - 1 + 9
f(x) = - x² + 2x + 8
x₁ = -2 and x₂ = 4, so also:
f(x) = -(x + 2)(x - 4)
Answer:
g(x) = -1 (x + 2)(x − 4)
Step-by-step explanation:
To write the equation of the function in factored form, g(x) = a(x − r1)(x − r2), find the values of r1, r2, and a.
The function has x-intercepts of -2 and 4, so (x − (-2)), or (x + 2), and (x − 4) are factors of the equation.
To find a, look at how the value of y changes for 1 unit to the right of the vertex. The y-value goes down 1 unit for a point 1 unit to the right of the vertex, so a = -1.
The equation of this quadratic function is g(x) = -(x + 2)(x − 4).
