SOMEONE PLEASE HELP! ITS ALMOST DUE!
Answer and Step-by-step explanation:
For this triangle, to find x, we will use the cosine trigonometric function.
cosine functions look like this:
[tex]cos(\theta) = \frac{adjacent}{hypotenuse}[/tex]
(The weird looking symbol is called theta, and represents an angle measurement)
Plug in the values into the equation.
cos(42) = [tex]\frac{x}{15}[/tex]
Multiply both sides by 15.
15(cos(42)) = x
Plug into a calculator.
11.1472 is the answer.

Solve w^2+13w+42=0 by factoring.
Answer: {-7, -6}
Explanation: When an equation has a squared term in it,
it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to 0, then factor.
Since this equation is already set equal to 0, we can factor the left side.
The left side is a trinomial that can be
factored as the product of two binomials.
The first term in each binomial will be a factor of the w².
Since w² factors a w · w, we use a w as our first term.
For the last terms, we use factors of 42 that add
to 13 and these factors are +7 and +6.
So we have (w + 7)(w + 6) = 0.
So either w + 7 = 0 or w + 6 = 0.
Solving for w in each equation, we find that our solution set is {-7, -6}.
A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 S
Complete Question:
A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 Seconds.
a. what acceleration is imparted to the paper?
b. if the mass of the paper is 0.003 kg, what force does the boxer exert on it?
c. how much force does the paper exert on the boxer?
Answer:
a. Acceleration = 454.55m/s².
b. Force = 1.36N
c. Force = -1.36N
Step-by-step explanation:
Given the following data;
Final velocity = 20m/s
Time = 0.044 seconds.
Since the paper is at rest, we know that it's initial velocity is equal to 0m/s.
a. To find acceleration;
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Substituting into the equation, we have;
[tex]a = \frac{20 - 0}{0.044}[/tex]
[tex]a = \frac{20}{0.044}[/tex]
Acceleration = 454.55m/s²
b. To find the force exerted by the boxer;
Mass = 0.003kg
Force = mass * acceleration
Force = 0.003 * 454.55
Force = 1.36N
c. To find the force exerted by the paper;
According to Newton's third law of motion which states that, for every action there is an equal and opposite reaction. Therefore, the paper exerts an equal but opposite force on the boxer.
Force = -1.36N

In the triangle below, ∠Q is a right angle. Which ratio would be equivalent to the ratio of sin∠R?
a) cos∠Q
b) cos∠S
c) sin∠Q
d) sin∠S
Answer:
b) cos∠SStep-by-step explanation:
sin ∠R = SQ/SR
This is same as:
cos SCorrect option is b)
cos<Q
Lets do
[tex]\\ \sf\longmapsto sin<R=\dfrac{P}{H}[/tex]
[tex]\\ \sf\longmapsto sin<R=\dfrac{SQ}{SR}[/tex]
Now
[tex]\\ \sf\longmapsto cos<Q=\dfrac{B}{H}[/tex]
[tex]\\ \sf\longmapsto cos<Q=\dfrac{SQ}{SR}[/tex]
A penny is about 5×10−3 feet thick. The One World Trade Center building is about 2,000 feet tall. How many pennies would be in a stack of pennies as tall as the One World Trade Center building?
Answer:
400000 pennies
Step-by-step explanation:
A penny is about 5×10^-3 feet thick. The One World Trade Center building is about 2,000 feet tall.
The number of pennies that would be in a stack of pennies as tall as the One World Trade Center building is calculated as:
Height of the building ÷ Thickness of a penny
Height of the building = 2000 feet
Thickness of a penny = 5 × 10^-3 feet
Hence:
= 2000feet/ 5 × 10^-3 feet
= 400000 pennies

Write a polynomial equation of degree 4 that has the following roots: -1 repeated three times and 4.
Answer:
[tex] {x}^{4} - {x}^{3} - {9x}^{2} - {11x}^{2} - 4 [/tex]
Step-by-step explanation:
Since the roots are -1,-1,-1 and 4 we can that as.
[tex](x + 1)(x + 1)(x + 1)(x - 4)[/tex]
x+1=0, x equal -1, and x-4=0 and x equal 4. Then apply the foil method to one at a time and you equal the answer above.
