2(cos^4 60 +sin^4 30) -(tan^2 60 +cot^2 45) +3*sec^2 30
The value of the expression \(2(cos^4 60 + sin^4 30) -(tan^2 60 + cot^2 45) + 3\times sec^2 30 is 33/4.\)
Let's simplify the expression step by step:
Recall the values of trigonometric functions for common angles:
cos(60°) = 1/2
sin(30°) = 1/2
tan(60°) = √(3)
cot(45°) = 1
sec(30°) = 2
Substitute the values into the expression:
\(2(cos^4 60 + sin^4 30) - (tan^2 60 + cot^2 45) + 3sec^2 30\)
= \(2((1/2)^4 + (1/2)^4) - (\sqrt{(3)^2 + 1^2} ) + 3(2^2)\)
= 2(1/16 + 1/16) - (3 + 1) + 3*4
= 2(1/8) - 4 + 12
= 1/4 - 4 + 12
= -15/4 + 12
= -15/4 + 48/4
= 33/4
Therefore, the value of the expression \(2(cos^4 60 + sin^4 30) -(tan^2 60 + cot^2 45) + 3\times sec^2 30 is 33/4.\)

Answer:
y = 1/3x +3
Step-by-step explanation:
Here, it will be convenient to write the equation in "slope-intercept form." That looks like ...
y = mx +b . . . . . line with slope m and y-intercept b
__
The y-intercept is the y-value where the line crosses the y-axis. On your graph, there is a point there: (0, 3). That means the y-intercept is b=3.
The slope is the "rise" divided by the "run". The points on your graph are 3 units apart horizontally (run = 3). The point on the right is 1 unit above the point to its left (rise = 1). This means the slope of the line is ...
m = rise/run = 1/3
Now, you have what you need to write the equation:

graph h(x)=(x-1)^2-9
The graph of h(x) = (x-1)^2 - 9 is a U-shaped parabola that opens upwards, with the vertex at (1, -9), and it extends indefinitely in both directions.
The function h(x) = (x-1)^2 - 9 represents a quadratic equation. Let's analyze the different components of the equation to understand the behavior of the graph.
The term (x-1)^2 represents a quadratic term. It indicates that the graph will have a parabolic shape. The coefficient in front of the quadratic term (1) implies that the parabola opens upwards.
The constant term -9 shifts the graph downward by 9 units. This means the vertex of the parabola will be at the point (1, -9).
Based on this information, we can draw the following conclusions:
The graph will be a U-shaped curve with the vertex at (1, -9).
The vertex represents the minimum point of the parabola since it opens upward.
The parabola will be symmetric with respect to the vertical line x = 1 since the coefficient of the quadratic term is positive.
The graph will extend indefinitely in both directions.
To accurately plot the graph, you can choose several x-values, substitute them into the equation to find the corresponding y-values, and then plot the points on the graph. Alternatively, you can use graphing software or calculators that can plot the graph of the equation for you.
Remember to label the axes and indicate the vertex at (1, -9) to provide a complete representation of the graph of h(x) = (x-1)^2 - 9.

The perimeter of an ICU ward, that is rectangular in shape, is 258 feet. The width is 37 feet less than the length. Find the dimensions of this ward.
length(ft)=
width(ft)=
Answer: length = 83, width= 46
Step-by-step explanation: 1. let's call the unknown dimensions x. We know that the formula for perimeter is 2(length) +2(width) so we can substitute.
2. After substituting, the equation should be 2(x) + 2(x-37)=258
3. Distribute. 2x+2x-74=258
4. Simplify. 4x-74=258
5. add 74 to both sides. 4x=332
6. x=83
7. We know that x was the length. The width was 37 less than the length (83). 83-37 is 46. So the length is 83, and the width is 46.
Answer:
Length = 83 ft
Width = 46 ft
Step-by-step explanation:
Rectangular perimeter = 2(length + width)
In this case:
258 = 2(length + width) Eq. 1
width = length - 37 Eq. 2
From Eq. 1:
258/2 = length + width
129 = length + width Eq. 3
Replacing Eq. 2 in Eq. 3
129 = length + (length-37)
129 + 37 = 2 length
166 = 2 length
166/2 = length
length = 83 ft
From Eq. 2:
width = length - 37
width = 83 -37
width = 46 ft
Check:
from Eq. 1:
258 = 2(width + length)
258 = 2(46 + 83)
258 = 2(129)

Yes. (The graph is that of a function)
(a) A. Domain: ]-∞,∞[. Range: [-4,∞[
(b) A. The intercepts are (-5,0) , (-1,0) and (0,5)
Explanation:
The vertical line test is a method to determine if a graph is a function by looking at its amount of intercepts with a random vertical. If there is more than one intercept with the random vertical line it isn't the graph of a function.
Here if you trace a random vertical line at any point of the graph you'll notice that it only intercepts it once. Hence it is a function's graph.
(a)
. The domain is given by the x-axis
On the graph, x can be any number: ]-∞,∞[
. The range is given by the y-axis
On the graph, y can be any number starting from -4 to higher : [-4,∞[
(b)
Intercepts are where the graph touches the x or y axis.
. The graph intercepts with the horizontal line (x-axis), at the point (-5,0) and (-1,0) : Notice y is = 0
. The graph intercepts with the vertical line (y-axis), at the point (0,5) : Notice x is = 0

The measure of side length EF in the right triangle is 24.
What is the measure of side length EF?The Pythagorean theorem states that the "square on the hypotenuse of a right-angled triangle is equal in area to the sum of the squares on the other two sides.
It is expressed as;
c² = a² + b²
From the diagram:
Hypotenuse DE = c = 26
Leg DF = a = 10
Leg EF = b = ?
Plug in the values and solve for b:
c² = a² + b²
26² = 10² + b²
676 = 100 + b²
b² = 676 - 100
b² = 576
b = +√576 ( we take the positive value since we are dealing with dimensions)
b = 24
Therefore, the length EF is 24.
Option C)24 is the correct answer.

EX #5: Based on the definition above, identify the following: A. Relative Maximum is __ where x = __ B. Relative Minimum is __ where x = __ C. Relative Minimum is __ where x = __
Based on the given graph, you can conclude:
A. Relative Maximum is f(x) = 1 where x = 2
(Because the relative maximum of a function is given by a point of the graph with a slope m = 0, but this point is not necessarily the absolute maximum. Furthermore, the concavity of the curve at this point is negative).
B. Relative minimum is f(x) = -8 where x = -3
C. Relative minimum is f(x) = 0 where x = 4
Both relative minima correspond to points in which the slope of the line is 0 and the concavity of the line is positive.

Y A chemist can purchase a 10% saline solution in 500 cubic centimeter containers, a 20% saline solution in 500 cubic centimeter containers, and a 50% saline solution in 1,000 cubic centimeter containers. He needs 12,000 cubic centimeters of 30% saline solution. How many containers of each type of solution should he purchase in order to form this solution
Step-by-step explanation:
ultimately you need to end up with 30% solution
with 10%, 20%, and 50%, you are forced to tamper with the various percentages to reach the desired goal.
Since it is an even 12,000 (i.e. no 12500) and you have no hard container volumes to deal with, therefore find the easiest combination to reach 30%. In this case, (10%+50%)/2 = 30%
So therefore you need 12000 cubic centimeters of liquid, half of it being 50% and half being 10%.
12000/2 = 6000 cubic centimeters each
for 50%, each container is 1,000 cubic centimeters, so 6000/1000 =6 containers for 10% each container is 500 cubic centimeters, so 6000/500 = 12 containers
Therefore, you need 6 containers of 50% solution and 12 containers of 10% solution.

The total number of seats available for the baseball game can be calculated by adding the number of box and club seats available whch is found to be 25,200.
What is the game of baseball?The game of baseball can be used to teach various mathematical concepts, such as probability, statistics, graphing, estimation, and basic arithmetic. The game can also be used to introduce concepts such as geometry and trigonometry, as well as to build problem-solving skills.
The total number of seats available can be calculated by adding the number of box and club seats available, which is
12,600 + 5400 = 18,000.
This total can then be multiplied by the respective percentages of the other two categories to get the total number of seats available.
For instance, the total number of bleacher seats available can be calculated by multiplying 12,000 by 18%.
12,000 x 0.18 = 2,160
Similarly, the total number of grandstand seats available can be calculated by multiplying 12,000 by 42%.
12,000 x 0.42 = 5,040
Hence, the total number of seats available for the baseball game is
18,000 + 2,160 + 5,040 = 25,200.

Sally made a profit of $2500 after selling stocks for $19000 after 2.5 years. What was her average annual percentage gain?
13.25%
6.06%
3.78%
Sally's average annual percentage gain is approximately 5.26%.
To calculate Sally's average annual percentage gain, we can use the formula:
Average Annual Percentage Gain = (Profit / Initial Investment) * (1 / Time) * 100
Profit = $2500
Initial Investment = $19000
Time = 2.5 years
Substituting the values into the formula:
Average Annual Percentage Gain = (2500 / 19000) * (1 / 2.5) * 100
= (0.1316) * (0.4) * 100
= 5.26
Therefore, Sally's average annual percentage gain is approximately 5.26%.
