The solution is, the simplified value of the expression is, 1.
To simplify the expression, we need the trigonometric identities given:
we know that,
1. cot=1/tan
2. tan=sin/cos
3. sec=1/cos
so, we have,
cot θ sec θ sin θ = 1/tanθ(1/cosθ)sinθ
= (1/(sinθ/cosθ))(1/cosθ)sinθ
= (cosθ / sinθ) (1/cosθ)sinθ
= 1
The expression is equal to 1.

Four times a number plus five times the number is the same as ten more than eight
times the number. Find the number
Answer:
The number is 10.
Step-by-step explanation:
Given that:
Four times a number plus five times the number is the same as ten more than eight times the number.
Let,
x represent the number.
According to given statement,
4 times the number + 5 times the number = 10 + eight times the number
4x+5x=10+8x
Solving the equation,
9x=10+8x
Subtracting 8x from both sides
9x-8x=10+8x-8x
x=10
Hence,
The number is 10.
Alyssa invests $2600 in a savings account at 9% simple interest. How much does she have in her account after 3 years?
Answer:
$3,302
Step-by-step explanation:
9% x 3 (years) = 27%
$2600 x 27% = 702
$2600 + 702 = $3302
4. Find m_1.
140°
650
Answer:
∠ 1 = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
140° is an exterior angle of the triangle, thus
90° + ∠ 1 = 140° ( subtract 90° from both sides )
∠ 1 = 50°
Answer:
50 degrees
Step-by-step explanation:
To find the measure of angle 1, you must first find the other unknown angle in the triangle. You can find this through supplementary angles. The bottom angle as well as 140 must be equal to 180 because they are supplementary, so to find it solve 180-140, which is 40. Now two of the angles in the triangle are known, one is 40 and the other is 90 as shown by the square. You know that every angle equals 180 degrees, so to find angle 1 add the known angles and subtract that from 180. 180-(90+40), which equals 50. So m<1=50.

What is the difference between the let statements of consecutive even integers and consecutive odd integers
Answer and Step-by-step explanation:
The word, "Consecutive" means, "Back-to-back" or "One after the other." Therefore, consider these integers:
1, 2, 3, 4, 5, 6, 7, 8, . . .
If we write down these integers in such a way that only even integers follow back-to-back, we have:
2, 4, 6, 8, . . .
If we write down these integers in such a way that only odd integers follow back-to-back, we have:
1, 3, 5, 7, . . .
Since 2, 4, 6, 8, . . . Are all even integers that follow back-to-back, then this is known of consecutive even integers.
Since 1, 3, 5, 7, . . . Are all odd integers that follow back-to-back, then this is known of consecutive odd integers.
In a survey, 9 out of 10 dentists recommend PurWhite toothpaste for their patients. If 80 dentists were surveyed, how many doctors recommend PurWhite toothpaste?
Answer:
72 dentists
Step-by-step explanation:
In this case, we can multiply 80 by 9/10 or .9 to get our answer.
If we were to multiply by 9/10 it would look like this:
[tex]80 * \frac{9}{10} \\\frac{720}{10} = 72[/tex]
But, if we were to multiply by .90 (remember that 9/10 = .9) it would look like this:
[tex]80(.90) = 72[/tex]
Therefore, if 9 out of 10 dentists recommended PurWhite toothpaste and 80 were surveyed then 72 out of the 80 would have recommended it.
I hope this helps!!

Answer:
y > 3x - 3
Step-by-step explanation:
First off, to write a linear equation or linear inequality, we use the slope-intercept form: y = mx + b, where m represents the slope of a line, and b represents the y-intercept.
The slope of the line is found using rise/run. The rise, in this case, is 3, and the run is 1. 3/1 is 3. So, we can replace the m in the equation with 3 to get:
y = 3x + b
To find b, simply look for where the line crosses the y-axis (vertical line). In this case, it's -3.
The equation you have now is y = 3x + (-3), which is y = 3x - 3.
You're not done yet. A dotted line like here means a point ON the line is not a solution to the equation, so you have to replace the = with < or >. In this case, the shaded region is everything GREATER THAN -3, meaning you use the > (greater than) symbol.
Your final answer is y > 3x - 3.
Hope this helped!

The other answer should get the Brainliest. Don't neglect awarding it. They are very good to get.
I'm only going to add a graph for you to see. All it does is point out what < and > mean.
As the other responder said, when the boundary is dotted, it is not included in the shaded part.
Also he pointed the difference between < and >. That is what I wanted to address. It is easy to tell.
< is less than the boundary and it is blue.
> is greater than, and it is green.
if the line is solid, then ≤ or ≥ is used.

Answer:
0=3/8
1=1 5/8
2= 4/2
i think?
Step-by-step explanation:
3/8 is less than a whole so it is 0
1 5/8 and 4/2 is 2 if simplified and 1 5/8 is less than 2 so 1 5/8 is 1 and 4/2 is 2

the 6 month return rate was .0175, so double that to get the annual rate.
Solve for the missing variable. Round your answer to the nearest tenth.

Answer:
x = 7
Step-by-step explanation:
We assume the hash marks are intended to indicate both triangles are isosceles. Then the right-end angle of the upper triangle is ...
180° -2(75°) = 30°
Its complement is the supplement of the "missing variable" angle.
90° -30° = 180° -(18x -6)°
18x = 126 . . . . . rearranging (add 18x -60)
x = 7 . . . . . . . . . divide by 18

The length of each of the two congruent sides of an isosceles triangle is 2n + 7 and the length of the third side is 3n. Write an expression for the length of the triangle’s perimeter.
Answer:
7n+14
Step-by-step explanation:
There are two sides that both measure 2n+7, we need 2 of those
2n+7+2n+7=4n+14
We still have the third side left, 3n.
4n+14+3n
combine like terms
7n+14

Not sure
What is an equation of the line that passes through the points (5, 8) and (5,3)?
Answer:
x = 5
Step-by-step explanation:
to find the slope of the line you take the difference of the y-values divided by the difference of the x-values; the denominator results in zero
When the denominator for slope is zero then you know the line will not intersect the y-axis at all and the line will be vertical and intersect the x-axis at the x-coordinate of any known point
any fraction with zero in the denominator is considered to be 'undefined'
any fraction with zero in the numerator is zero
