determine the value of sin theta + cos theta whole square is equal to 2 sin theta cos theta.
Answer:
That will be 1.
Step-by-step explanation:
an airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph what is its average speed for the total trip?
The average speed is the ratio of the total distance to the total time. Then the average speed of the airplane will be 698.19 miles per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
An airplane files 867 miles with a constant speed of 612 mph and then another 1984 miles with a constant speed of 744 mph.
Then time taken for the first trip will be
t₁ = 867 / 612
t₁ = 1.4167 hours
Then time taken for the second trip will be
t₂ = 1984 / 744
t₂ = 2.6667 hours
Then the average speed is the ratio of the total distance to the total time.
The total distance will be
Total distance = 867 + 1984
Total distance = 2851 miles
The total time will be
Total distance = 1.4167 + 2.6667
Total distance = 4.0834 hours
Then the average speed will be
Average speed = 2851 / 4.0834
Average speed = 698.19 mi/h

Question:
Using only a compass and a straightedge, you are constructing a line perpendicular to AB and passing through a given point, M, on AB. With a compass of set width, you have drawn arcs that intersect AB on each side of M and marked the two intersection points as P and Q.
Options:
-P and set its width to M
-M and set its width beyond P
-P and set its width beyond M
-M and set its width to half the distance between P and M
The construction goes with P and set its width to M.
The correct option is (A).
What is perpendicular bisector ?
A perpendicular bisector of a line segment is a line segment perpendicular to and passing through the midpoint of figure.
Now, a line perpendicular to AB and passing through an external point M.
first step :Put the compass needle on M and, keep the compass width the same then draw two arcs that intersect AB.
Second step: After drawing arcs, from the intersecting points named P and Q.
Now, keeping the width of compass same as before and to the opposite side of M draw an arc named it as M'
Third step: Using straightedge draw line passes through M.
The lines which passes through M will be perpendicular to AB.
The above discussed are steps to draw perpendicular bisector of AB.

Which expression is equivalent to n2 + 26n + 88 for all values of n?
(n + 8)(n + 11)
(n + 4)(n + 22)
(n + 4)(n + 24)
(n + 8)(n + 18)
Answer:
(n + 4)(n+ 22)
Step-by-step explanation:
One way to determine which factored expression is accurate is by asking the question: "Which two numbers multiply to 88, but add to 26?" If you are having difficulty using this method, you can always try the guess-and-check method with a multiple choice question. This way involves multiplying the terms inside one set of parentheses with the terms inside the other set of parentheses.
Step #1: Multiply the first terms
(n + 4)(n + 22) ----> n x n = n²
Step #2: Multiply the inside terms
(n + 4)(n + 22) -----> 4 x n = 4n
Step #3: Multiply the outside terms
(n + 4)(n + 22) -----> n x 22 = 22n
Step #4: Multiply the last terms
(n + 4)(n + 22) -----> 4 x 22 = 88
Step #5: Write the new expanded equation and simplify
(n + 4)(n + 22) -----> n² + 4n + 22n + 88 -----> n² + 26n + 88

Which expresses this solution?
The equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]
How to express the solution?The equation is given as:
x² - 10x + 13 = 0
The solution to a quadratic equation is represented by:
[tex]x =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}[/tex]
So, we have:
[tex]x =\frac{10 \pm \sqrt{(-10)^2 -4 * 1 * 13}}{2 * 1}[/tex]
Evaluate the radicand
[tex]x =\frac{10 \pm \sqrt{48}}{2}[/tex]
Take the square root of 48
[tex]x =\frac{10 \pm 4\sqrt{3}}{2}[/tex]
Divide
[tex]x =5 \pm 2\sqrt{3}[/tex]
Hence, the equation that expresses the solution to the quadratic equation x² - 10x + 13 = 0 is [tex]x =5 \pm 2\sqrt{3}[/tex]
