Let (-3,5) be a point on the terminal side of theta. Find the exact values of sin theta, secant theta, and tangent theta
Can someone please help me out with this? If possible, providing a diagram would be helpful!
Answer:
Cosθ = 0.5145
Sinθ = 0.8575
Secθ = 1.9436
tanθ = 1.667
Step-by-step explanation:
From the figure attached,
Point P(-3, 5) is on the terminal side and AB is the initial side of the angle PAB.
If m∠PAB = θ
AB = [tex]\sqrt{(3)^{2}+(5)^{2}}[/tex]
= [tex]\sqrt{34}[/tex]
= 5.831
Then Cosθ = [tex]\frac{AB}{AP}[/tex] = [tex]\frac{3}{5.831}[/tex]
Cosθ = 0.5145
Sinθ = [tex]\frac{PB}{AP}[/tex]
Sinθ = [tex]\frac{5}{5.831}[/tex]
Sinθ = 0.8575
Secθ = [tex]\frac{1}{\text{Cos}\theta}[/tex]
Secθ = [tex]\frac{1}{0.5145}[/tex]
Secθ = 1.944
tanθ = [tex]\frac{PB}{AB}[/tex]
tanθ = [tex]\frac{5}{3}[/tex]
tanθ = 1.667

Answer:
The surface area of the box increase by 0.2P (the perimeter of the base multiplied by 0.2)
Step-by-step explanation:
we know that
The surface area of the rectangular prism is equal to where B is the area of the base P is the perimeter of the base h is the height of the prism If the height is increased by 0.2 then The surface area of the box increase by 0.2P (the perimeter of the base multiplied by 0.2)

Step-by-step explanation:
from the top of a tree the angle of depression of a rock on the ground is 49 degrees. If the tree is 18.5 m tall, how far is the rock from the base of the tree?
Answer:
Step-by-step explanation:
If you were to sit in the very top of said tree and look directly straight, your line of vision would be parallel to the ground. The angle of depression is in between your line of vision and the rock. When you look down at the rock, your line of vision to the rock is a transversal between the 2 parallel lines. With this being the case, the angle of depression is alternate interior with the angle made on the ground from the rock to the top of the tree. See the illustration I attached below.
We are looking for the distance on the ground between the tree and the rock, which we will call x. The side opposite the reference angle is the height of the tree and the side adjacent to the reference angle is x. Side opposite over side adjacent is the tangent ratio. Therefore,
[tex]tan(49)=\frac{18.5}{x}[/tex] and
[tex]x=\frac{18.5}{tan(49)}[/tex] and on your calculator in degree mode, you will find that
x = 16.08 m

(15 feet
What is the least amount of wall paper Tara will need to
cover the entire area of the wall?
A 39 square feet
C 350 square feet
B 78 square feet
D 360 square feet
Answer:
D. 360 square feet
Step-by-step explanation:
The area of Tara's wall is 24 times 15 which equals 360 sq. feet. This means she would need the same amount of wallpaper to cover it.

Answer:
X= 55/3 = 18.333
Step-by-step explanation:
Step 1 : Solving a Single Variable Equation : 1.1
Solve : 3x-55 = 0
Add 55 to both sides of the equation : 3x = 55
Divide both sides of the equation by 3: x = 55/3 = 18.333
Answer: X= 55/3 = 18.333

How many intersections are there of the graphs of the equations below? One-halfx + 5y = 6 3x + 30y = 36 none one two infinitely many
Answer:
infinitely many
Step-by-step explanation:
You have the system
(1/2)x + 5y = 6
3x + 30y = 36
Multiplying the first equation by 6 results in 3x + 30y = 36, which is exactly the same as the second equation. The two graphs coincide, and so there are infinitely many solutions to this system
Answer:
infinitely many
Step-by-step explanation:
1/2x + 5y = 6 ⇒ x+10y=123x + 30y = 36 ⇒ x+10y=12As we see, these are equal lines, they overlap, so there are infinitely many intersections

Step-by-step explanation:
Use FOIL for this:
(5r+2)(3r-4)
First: 5r × 3r = 15r²
Outer: 5r × (-4) = -20r
Inner: 2 × 3r = 6r

Will the following list have a large or small standard deviation?
7, 6, 5, 8, 9, 1, 0, 4, 3, 2
A) small
B) not enough information
C) large
Answer:
the standared deviation =2.87 so it is small
Step-by-step explanation:
to calculate the standard deviation of those numbers:
1- Work out the Mean (the simple average of the numbers)
(7+6+5+8+9+1+0+4+3+2)/10=4.5
Then for each number: subtract the Mean and square the result.
[(7 - 4.5)^2 + ... + (2 - 4.5)^2]/10=8.25
√8.25=2.87≅3
Answer:
A. Small

Write the formula for
the function whose
parabola is narrow,
opens downward, has a
y-intercept of (0,-3.14),
and has NO x-intercepts.
Answer:
Equation of the parabola x² = -12.56 y
Step-by-step explanation:
Explanation:-
Given Y- intercept ( 0, -3.14)
Given Focus is ( 0 , -a) = ( 0, -3.14)
So a = 3.14 center C(0,0)
The graph of the parabola is downwards and the axis of the parabola is Y-axis.
Equation of the standard parabola x² = -4 a y
x² = -4 (3.14) y
x² = - 12.56 y
Conclusion:-
Equation of the parabola x² = -12.56 y
Make x the subject of:
h = 4 ( x + 3y ) + 2
Step-by-step explanation:
h = 4(x+3y)+2
h = 4x + 12y + 2
4x = 14y
Answer:
(h-12y-2)/4
Step-by-step explanation:
h=4x+12y +2
h-12y-2=4x
x=(h-12y-2)/4
ABCE is a cyclic quadrilateral. AED and BCD are straight lines. AC= CD, angle ABC= 45 degrees and angle ACE = 20 degrees. Work out angle ECD
Answer:
∠ECD is 110°
Step-by-step explanation:
For a cyclic quadrilateral,
∠ABC + ∠AEC = 180°
Therefore ∠AEC = 180° - 45° = 135°
∠CAE + ∠ACE + ∠AEC = 180° (Angles in a triangle)
Therefore ∠CAE = 180 - 20 - 135 = 25°
∠CAE = ∠CDA = 25° (Base angles of isosceles triangle ΔCAD)
∠CED + ∠AEC = 180°(Sum of angles on a straight line)
Therefore ∠CED + 135° = 180°
∠CED = 180° - 135° = 45°
∠ECD + ∠CED + ∠CDA = 180°
Therefore ∠ECD = 180° - (∠CED + ∠CDA)
∠ECD = 180° - (45° + 25°) = 110°
Therefore, ∠ECD = 110°.
How long would it take an investment to triple if it earns 1.5% interest, compounded monthly? Round your answer to the nearest hundredth.
Answer:
73.3 years
Step-by-step explanation:
Use the Compound Amount formula:
A = P(1 + r/n)^(n*t)
Here A = 3P, r = 0.015, n = 12, and so we have:
3 = (1 + 0.015/12)^(12*t). Find t (in years)
3 = (1.00125)^(12*t)
Take the log of both sides. We get:
log 3 = (12*t)(log 1.00125), or 0.47712 = (12*t)(5.425*10^(-4)
0.47712
Solving this for t, we get t = --------------------------- = 73.3 years
(12)(5.425*10^(-4))

4) The width of a rectangle is 8 inches. The length is 4 times its
width
What is the area of the rectangle?
A) 35 in
306 1/4 ft.
A) 43 3/4 ft.
C) 280 fta
D)
Answer:
Length = 4 * 8 = 32
Area = width * length = 8 * 32 = 256 square inches
Step-by-step explanation:
Answer:
A =256 inches^2
Step-by-step explanation:
width = 8 inches
length = 4 w = 4*8 = 32
A = l*w
A = 32*8
A =256 inches^2
Which of the following is the inverse of the statement "If I do my homework,
then it will snow"?
O A. If I do not do my homework, then it will snow.
B. If it does not snow, then I will not do my homework.
C. If it snows, then I will do my homework.
D. If I do not do my homework, then it will not snow.
SUBMIT
Answer:
D. If I do not do my homework, then it will not snow.
Explanation:
An inverse of anything is the contrary or opposite of the given statement or idea or anything. And in a way, it is the same as the antonym, opposite or contradictory factor of the given point.
The given sentence/ proposition is-
if I do my homework, then it will snow.
In this sentence, the hypothesis of the homework getting done concludes that it will snow. So, for the inverse of this proposition, the positive nature of the sentence will be turned into a negative one.
Thus, the correct answer will be such that if the homework is not done, then it will also not snow. So, the correct answer is option D.
Answer: it’s D

My mom built a new sandbox that is 3 \text { m}3 m3, start text, space, m, end text long, 2 \text { m}2 m2, start text, space, m, end text wide, and 1 \text { m}1 m1, start text, space, m, end text high for my sister and me. Sand for the sandbox costs \$4.50$4.50dollar sign, 4, point, 50 per cubic meter. How much will it cost to completely fill the sandbox with sand? \$$dollar sign
Answer:
$27
Step-by-step explanation:
The dimensions of the sandbox (that is a rectangular prism) are 3m x 2m x 1m.
We need to first find the volume of the sandbox.
The volume of a rectangular prism is:
V = L * W * H
where L = length
W = Width
H = height
The volume of the sandbox is:
V = 3 * 2 * 1 = [tex]6 m^3[/tex]
Sand for the sandbox costs $4.50 per cubic meter.
The cost to completely fill the sandbox is:
4.50 * 6 = $27
