What is the exact value of sec 0 in simplest form with a rational denominator?
Answers
Answer:
Step-by-step explanation:
Don't use 0 as a substitute for θ. 0 is always 0.
cosθ = -5/(2√15)
secθ = 1/cosθ = -2√15/5
The exact value of sec θ is -8.6/5.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Point(-5, -7).
Here, x= -5 and y= -7
So, r = √x² + y²
r= √(-5)² + (-7)²
r= √25 + 49
r = √74
r= 8.6
So, sec θ= H/ B
= r/x
= 8.6/ (-5)
= -8.6/ 5

substitute this equation x+3y=18 & -x-4y=-25
Answers
Answer:
{x,y} = {3/7,-43/7}
Step-by-step explanation:
System of Linear Equations entered :
[1] x + 3y = -18
[2] -x + 4y = -25
Graphic Representation of the Equations :
3y + x = -18 4y - x = -25
Solve by Substitution :
// Solve equation [1] for the variable x
[1] x = -3y - 18
// Plug this in for variable x in equation [2]
[2] -(-3y-18) + 4y = -25
[2] 7y = -43
// Solve equation [2] for the variable y
[2] 7y = - 43
[2] y = - 43/7
// By now we know this much :
x = -3y-18
y = -43/7
// Use the y value to solve for x
x = -3(-43/7)-18 = 3/7
Solution :
{x,y} = {3/7,-43/7}

Therefore, the vertically opposite angle to angle of 25 is also equal to 25
Now, we have to find x
Therefore, x=180-25 ( interer angles on the same side of the transversal so addition of both angles is 180)

A cylinder has a volume of 48 cubic cm. What is the volume of a cone with the same radius and height?
Answers
Answer:
16 cm^3
Step-by-step explanation:
The computation of the volume of a cone is shown below:
As we know that
The Volume of the cylinder is πr^h
And the volume of the cone is 1 ÷ 3 πr^h
Also the height and the radius is the same for both
so, the volume of the cone is
= 1 ÷ 3 × 48

If lines a and b are parallel determine the value of x.
Answers
==================================================
Work Shown:
If line a is parallel to line b, then the alternate interior angles (4x-30) and (2x) are equal to one another.
Let's solve for x
4x-30 = 2x
4x-2x = 30
2x = 30
x = 30/2
x = 15
The 2 angles are the same because they are alternate interior angles, so...
4x - 30 = 2x
4x = 2x + 30
2x = 30
X = 15

A temperature in degrees Fahrenheit is shown in expanded notation. ( 9 × 10 ) + ( 4 × 0.1 ) How is this temperature in degrees Fahrenheit written a numeral?
Answers
Answer:
90.4 degrees.
Step-by-step explanation:
(9 x 10) + (4 x 0.1)
= 90 + 0.4
= 90.4.
The Temperature in Fahrenheit is 90.4 F.
What is Expanded form?The division of numbers into groups according to place value, such as ones, tens, hundreds, thousands, ten thousand, and so forth, results in the expanded form of the number. The expanded version of the number is the one that is represented by the sum of each digit times its place value.
Given:
Expanded notation. ( 9 × 10 ) + ( 4 × 0.1 )
Now, simplifying the expression
= (9 x 10) + (4 x 0.1)
= 90 + 0.4
= 90.4.
Hence, the Temperature in Fahrenheit is 90.4 F.
