In which quadrant does θ lie if the following statements are true:
sin
θ
>
0
and
tan
θ
>
0
sinθ>0 and tanθ>0
Answer:
Quadrant I
Step-by-step explanation:
We are told that sin is positive (greater than 0) and tan is positive (greater than 0).
We know that sin is positive in quadrants I and II.
We also know that tan is positive in quadrants I and III.
Since both conditions share Quadrant I, the answer is Quadrant I.

A company studied the number of lost time acedents occurring at its Brownsville, Texas, plant. Historical records show that 0% of the employees suffered lost
time accidents last yean Management believes that a special safety program will reduce such accidents to 6% during the current year. In addition, it estimates
that 10% of employees who had lost time accidents last year will experience a lost time accident during the current yean
a. What percentage of the employees will experience lost-time accidents in both years (to 2 decimale)
0.015
b. What percentage of the employees will suffer at least one lost time accident over the two year period (to 2 decimals)?

Hint) Check My Work
outon kry
Answer:
A) 0.01
B) 0.07
Step-by-step explanation:
We are given;
P(accidents last year) = 0% = 0
P(accidents this year) = 6% = 0.06
P(accidents last year | accidents this year) = 10% = 0.1
A) We want to find the percentage of the employees will experience lost-time accidents in both years.
From multiplication rule in probability, we know that;
P(A & B) = P(A) × P(B|A) = P(B) × P(A|B)
Thus;
P(accident in both years) = P(accidents this year) × P(accidents last year | accidents this year)
P(accident in both years) = 0.06 × 0.1
P(accident in both years) = 0.006
To 2 decimal places gives; 0.01
B) from the addition rule, we know that;
P(A or B) = P(A) + P(B) - P(A & B)
Thus;
P(accident last year or this year) = P(accidents last year) + P(accidents this year) - P(accident in both years)
P(accident last year or this year) = 0 + 0.06 + 0.006 = 0.066
To 2 decimal places = 0.07

Give the limits of integration for evaluating the integral
∭f(r,θ,z)dz r dr dθ
as an iterated integral over the region that is bounded below by the plane z = 0, on the side by the cylinder r=cosθ and on top by the paraboloid z=3r^2.
Answer:
θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3
Step-by-step explanation:
Since the integration is in cylindrical coordinates, θ is integrated from 0 to 2π.
Since r = cosθ
when θ = 0, r = cos0 = 1
when θ = 2π, r = cos2π = -1
Since the region is bounded below by the plane z = 0, and on the top by the paraboloid z = 3r², z is integrated from z = 0 to z = 3r².
So, when r = 1, z = 3r² = 3(1)² = 3
when r = -1, z = 3r² = 3(-1)² = 3
So, the limits of integration of
∭f(r,θ,z)dz r dr dθ are θ = 0 to θ = 2π, r = 1 to r = -1 and z = 0 to z = 3

Chauncey is building a storage bench for his son’s playroom. The storage bench will fit into the corner and against two walls to form a triangle. Chauncey wants to buy a triangular shaped cover for the bench.
Formula for Area of Triangle:
A = ½ x b x h
(the photo is below)
If the base of the storage bench is 2 ½ ft. and the height along one side of the wall is 4 ½ ft. What is the area of the triangular cover?
Answer:
2.5 times 4.5 times .5 = 5.625 ft squared
Step-by-step explanation:
Lets look at our Formula
.5 times base of triangle (b) times height of triangle (h)
Based on the photo, the height is 4.5 feet and the base is 2.5 feet.
4.5 times 2.5 times .5 (the 1/2 in the formula) = 5.625 ft squared.
Remember that it is 1/2 times the base and height, b/c triangle is half of square. Ft squared because ft times ft equals ft squared

Step-by-step explanation:
a straight line passing through A(3,2) and B(5,y) has gradient -2. find the value of y
Step-by-step explanation:
[tex]gradient \: = \: \frac{y2 - y1}{x2 - x1} [/tex]
y2 = y , x2 = 5
y1 = 2 , x1 = 3
[tex] - 2 \: = \: \frac{y - 2}{5 - 3} [/tex]
-4 = y-2 ==> y = -2
Answer:
y=-2
Step-by-step explanation:
For a line containing the points (X1,Y1) and (X2,Y2), the gradient/slope is equal to (Y2-Y1)/(X2-X1).
Therefore for a line with gradient -2 and points (3,2) and (5,y), we can say:
-2=(y-2)/(5-3)
-2(2)=y-2
y=-4+2
y=-2
A fair coin is tossed 5 times. Compute the probability of tossing 5 heads in a row.
Answer:
50%
Step-by-step explanation:
There is 2 side out of 100% half is 50 :D gl and mb if its wrong!
Answer:
* Here we assume that the coin tossed is fair.
Probability of event A = # Favorable cases for event A/ # Exhaustive cases for event B
Where
Favorable cases means outcomes of an experiment that favors a particular event
Exhaustive cases means, number of total possible outcomes.
For tossing a coin one time:
# Favorable cases = 1 (getting head)
# Exhaustive cases = 2 (two outcomes, say, head and tail)
So, P(getting head in a single toss) = 1/2
For tossing a coin two times:
# Favorable cases = 1 (getting 2 heads, say, HH)
# Exhaustive cases = 2*2 or 2^2 (4 outcomes, say, HH, HT, TH, TT)
So, P(getting 2 heads in two tosses of a coin) = 1/4
Similarly, for tossing a coin five times:
# Favorable cases = 1 (getting 3 heads, say, HHHHH)
# Exhaustive cases = 2*2*2*2*2 or 2^5 (32 outcomes, say, HHHHH, THHHH, ..... etc)
So, P(getting head in 5 tosses of a coin) = 1/32

Option B is correct. The measurement of the angle m in the circle given is 56degrees
Geometry deals with the measurement of properties of lines, solids, and angles.
The diagram given in the question is a circle. To get the value of d, we will use one of the circle theorems which states;
The angle at the vertex is equal to half the sum in its intercepted arcs as shown:[tex]75=\frac{1}{2} (m\angle d - 94)[/tex]
Cross multiply
[tex]75 \times 2 = m \angle d - 94\\150=m \angle d +94\\m \angle d = 150 - 94\\m \angle = 56^0[/tex]
Hence the measurement of the angle m is 56degrees

The perimeter of a rectangular garden is 44 meters. The length of the rectangle is 5 less than twice the width. Find the length and width of the rectangle.
please helppp
9514 1404 393
Answer:
width: 9 mlength: 13 mStep-by-step explanation:
Let w represent the width. Then the length is 2w-5, and the perimeter is ...
P = 2(L+W)
44 = 2((2w-5) +w)
44 = 6w -10
54 = 6w
9 = w
2(9) -5 = 13 = length
The length of the rectangle is 13 meters; the width is 9 meters.

Given g(x) = -2x – 4, find g(6).
Answer:
x= -16
Step-by-step explanation:
g(x) =-2x-4
g(6)=-2(6)-4
g(6) = -12-4
g(6)=-16
The value of g(6) for the given function g(x) = -2x – 4 will be -16.
What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
In another word, a linear function is a function that varies linearly with respect to the changing variable.
Given the function,
g(x) = -2x – 4
Now,
g(6) means value of g(x) at x = 6
So,
g(6) = -2(6) - 4
g(6) = -12 - 4 = -16
Hence "The value of g(6) for the given function g(x) = -2x – 4 will be -16".

Someone please help me! Write the equation in standard form!
Answer:
x^2+y^2=6^2
Step-by-step explanation:
The equation of a circle is (x-h)^2+(y-k)^2=r^2
where h is the x coordinate of the center, k is the y coordinate of the center, and r is the radius of the circle.
We can see the center is on 0,0, and the radius is 6, so our equation is
(x-0)^2+(y-0)^2=6^2
or
x^2+y^2=6^2
Answer:
[tex] x ^2 + y^2 = 36 [/tex]
Step-by-step explanation:
Center of the circle (h, k) =(0, 0)
Radius of the circle (r) = 6 units
Equation of circle in center radius form is given as:
[tex] (x-h) ^2 + (y-k) ^2 = r^2 [/tex]
[tex] (x-0) ^2 + (y-0) ^2 = (6)^2 [/tex]
