The answer is:
[tex]sin(F)=\frac{OppositeSide}{Hypotenuse}=\frac{55}{73}=0.75[/tex]
[tex]cos(F)=\frac{AdjacentSide}{Hypotenuse}=\frac{48}{73}=0.66\\\\tan(F)=\frac{OppositeSide}{AdjacentSide}=\frac{55}{48}=1.15[/tex]
Why?Since we are working with a right triangle, we can use the Pythagorean Theorem to know the missing side size (Opposite Side).
Pythagorean Theorem formula:
[tex]c^{2}=a^{2} +b^{2}[/tex]
Where:
[tex]c=hypotenuse=73\\a=AdjacentSide=48\\b=OppositeSide[/tex]
So, the opposite side will be:
[tex]OppositeSide=\sqrt{c^{2}-a^{2}}=\sqrt{73^{2}-48^{2}}=\sqrt{5329-2304} \\OppositeSide=\sqrt{3025}=55[/tex]
Then:
[tex]sin(F)=\frac{OppositeSide}{Hypotenuse}=\frac{55}{73}=0.75[/tex]
[tex]cos(F)=\frac{AdjacentSide}{Hypotenuse}=\frac{48}{73}=0.66\\\\tan(F)=\frac{OppositeSide}{AdjacentSide}=\frac{55}{48}=1.15[/tex]
Have a nice day!
Answer:
Sin F = 0.7534
Cos F = 0.6575
Tan F= 1.145
Step-by-step explanation:
From the given figure we can see that,
triangle DEF is right angled triangle
Base = DF = 48
Hypotenuse = EF = 73
Height = ED
To find ED
We have ,
Hypotenuse² = Base² + Height²
EF² = DF² + ED²
ED² = EF² - DF² = 73² - 482
ED² = 3025
ED = √3025 = 55
To find Sin (F)
Sin ∅ =Opposite side /Hypotenuse
Sin F = ED/EF = 55/73 = 0.7534
To find Sin (F)
Cos ∅ =Adjacent side /Hypotenuse
Cos F =DF/EF = 48/73 = 0.6575
To find Sin (F)
Tan ∅ =Opposite side /Adjacent side
Tan F = ED/DF = 55/48 = 1.145
The system of equations y=-2x+3 and y= x is graphed. What is the solution to the system of equations?
Answer:
1,1
Step-by-step explanation:
I did this earlier today
The solution of the system of equations in terms of (x,y) is (1,1)
The system of equations can either be solved using the simultaneous equation method or the elimination method. Here, we will be using the simultaneous equation method.
Given that:
y = -2x + 3 --- (1)
y = x ---- (2)
Let replace the value of y in equation (2) back to equation (1)
∴
y = -2x + 3 becomes:
x = -2x + 3
x + 2x = 3
3x = 3
x = 3/3
x = 1
Since (x) is = 1
From equation (2), we know that y = x
∴
y = 1
Therefore, we can conclude that the solution of the system of equations in terms of (x,y) is (1,1)

The perimeter of a parallelogram is 80 meters.the width of the parallelogram is 4 meters less than its length
Answer:
The length is 22 and the width is 18.
Step-by-step explanation:
You can solve for the length by using the perimeter formula.
P = 2l + 2w.
You know P = 80. You also know the length is l and the width is w = l - 4.
80 = 2l + 2(l - 4)
80 = 2l + 2l - 8
80 = 4l - 8
88 = 4l
22 = l
This means the width which is 4 meters less is 22 - 4 = 18.
Identify the initial amount a and the growth factor b in the exponential function. g(x) = 20 • 2x
Answer:
Initial amount: 20
Growth factor: The amount doubles for every integer increase of x
Step-by-step explanation:
I think the equation should be g(x) = 20(2^x) for it to be exponential.
The general form of an exponential equation is g(x) = a(b^x), where a is the initial amount when x = 0, and b is the base, or growth factor.
We can see the amount double by evaluating a few value..
g(0) = 20(2^0) = 20(1) = 20 (initial amount)
g(1) = 20(2^1) = 20(2) = 40
g(2) = 20(2^2) = 20(4) = 80
g(3) = 20(2^3) = 20(8) = 160

What type of lines will have no solution in a system of equations?
a: Parallel Lines
b: Intersecting Lines
Answer:
Since parallel lines never cross, then there can be no intersection; that is, for a system of equations that graphs as parallel lines, there can be no solution.
Parallel lines will have no solution in a system of equations because they never intersect, maintaining a constant distance apart and having the same slope.
In a system of equations, two parallel lines will have no solution. This is because parallel lines never intersect; they have the same slope but different y-intercepts and maintain a constant distance from each other.
According to the theorem if two straight lines do not meet a third line on the same plane, then they do not meet each other, which confirms that they are parallel.
Hence, option (a) 'Parallel Lines' is the correct answer to which type of lines will have no solution in a system of equations. In contrast, option (b) 'Intersecting Lines' represents lines that cross at a single point and have one solution where they intersect, which corresponds to that unique solution of the system.

Arc XPY is 3/4 of the circle.
XPY = 3/4 x 12PI = 9PI
Any smooth curve connecting two points is called an arc. The length of arc XPY is 9π cm.
What is the Length of an Arc?Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,
Length of an Arc = 2π×R×(θ°/360°)
where
θ is the angle, that which arc creates at the centre of the circle in degree.
A circle has 360°, while the angle made by arc XY is 90°. Therefore, the measure of the angle made by the arc XPY at the centre of the circle is 270°. Also, the radius of the circle is 6 cm, therefore, the length of XPY is,
Length of XPY = 2π×6cm×(270°/360°) = 9π cm
Hence, the length of arc XPY is 28.2743 cm.

How much do you need to subtract from 53/6 to make 8
To make 8 from 53/6, you need to subtract 5/6. This solution involves converting 8 to the same denominational fraction as 53/6 (which is 48/6) and then subtracting this from 53/6.
Explanation:The question asks how much you need to subtract from 53/6 to make 8. To find out, we start by expressing the desired final number and the given fraction:
Convert 8 to a fraction with a common denominator with 53/6, which is 6, so 8 equals 48/6.To find out how much to subtract from 53/6 to get 48/6, we subtract the two fractions: 53/6 - 48/6.The subtraction gives us 5/6. Therefore, you need to subtract 5/6 from 53/6 to make 8.This demonstrates a basic understanding of fraction subtraction and the concept of working backwards to solve a problem, both of which are key skills in mathematics.

Step-by-step explanation:
We can find the length of RT by using the Pythagorean theorem
sin theta = opposite side/ hypotenuse
sin 60 = 2 sqrt(3)/ RT
Multiply each side by RT
RT sin 60 = 2 sqrt(3)
Divide by sin 60
RT = 2 sqrt(3)/ sin 60
RT = 4
Then
tan theta = opposite side/ adjacent side
tan 45 = x/RT
tan 45 = x/4
4 tan 45 = x
4 = x
a ladder that is 20 feet long is leaning against the side of a building if the angle formed between the ladder and the ground is 75 how far is the bottom of the ladder from the base of the building
Answer:
Step-by-step explanation:
Take 20( cosine of 75 degrees)
the answer is 5 ft
Answer:
5.18 feet
Step-by-step explanation:
We have been given that a ladder that is 20 feet long is leaning against the side of a building if the angle formed between the ladder and the ground is 75 degrees.
We can see from the attachment that side with 20 feet is hypotenuse and side x is adjacent side to the angle 75 degrees.
[tex]\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}[/tex]
Substitute the given values:
[tex]\text{cos}(75^{\circ})=\frac{x}{20}[/tex]
[tex]\frac{x}{20}=\text{cos}(75^{\circ})[/tex]
[tex]\frac{x}{20}*20=20*\text{cos}(75^{\circ})[/tex]
[tex]x=20*0.258819045103[/tex]
[tex]x=5.1763809[/tex]
[tex]x\approx 5.18[/tex]
Therefore, the bottom of the ladder is 5.18 feet away from the base of the building.
A line passes through the point (4,–2) and is perpendicular to the line with the equation y = 2⁄3x + 4. What's the equation of the line?
Answer:
y= -3/2x + 1
Step-by-step explanation:
The slope of this line is 2/3. The slope of the line perpendicular to this line will be the negative reciprocal or -3/2.
Write the equation using the slope m=-3/2 and the point slope form.
[tex]y-y_1=m(x-x_1)\\y--2=-\frac{3}{2}(x-4)\\y+2=-\frac{3}{2}(x-4)[/tex]
This is the equation of the line. You can convert it to slope intercept form:
[tex]y+2=-\frac{3}{2}(x-4)\\y+2 = -\frac{3}{2}x + 3\\y=-\frac{3}{2}x +1[/tex]
(5y-12)+(-5y-1) Find the sum or difference.
Answer: -13
Step-by-step explanation:
5y -5y cancel out and the -12-1=-13 and that’s how you get -13.
The sum or difference of the given expression (5y-12)+(-5y-1) simplifies to -13.
Explanation:The original problem presented is to evaluate the expression (5y-12)+(-5y-1). The operation between the two parenthesis is a sum (as indicated by the '+').
To solve, execute the operation in each parenthesis then execute the operation between. The operation inside the first parenthesis is a subtraction, yielding 5y-12. Similarly, the operation inside the second parenthesis is also a subtraction, yielding -5y-1. However, it is a good practice to treat subtraction of whole numbers as adding a negative. Finally, the operation between the two results is a sum (5y-12+(-5y-1)).
The desired result is achieved by applying the appropriate algebraic rules. So, we can rewrite this as: (5y-12) + (-5y -1) = 5y -12 -5y -1 = 0y -13 = -13.
