Answer:
(identity has been verified)
Step-by-step explanation:
Verify the following identity:
tan(x)/sec(x) = sin(x)
Hint: | Eliminate the denominator on the left hand side.
Multiply both sides by sec(x):
tan(x) = ^?sec(x) sin(x)
Hint: | Express both sides in terms of sine and cosine.
Write secant as 1/cosine and tangent as sine/cosine:
sin(x)/cos(x) = ^?1/cos(x) sin(x)
Hint: | Come to a conclusion.
The left hand side and right hand side are identical:

help i don't know what to do please help
need help solving to complete the square
Answer:
b=9 and b=-21
Step-by-step explanation:
first step: move 195 to the other side by adding to get:
b^2+12b=189
now to find the constant you take the b value which is 12 divide that by 2 and square it. then add the product to both sides. 12/2=6, 6^2=36
b^2+12b+36=189+36
next factor b^2+12b+36.
(b+6)^2=225
square root both sides to get:
b+6=15 and b+6=-15
solve by subracting 6 to both sides and you get the 2 final answers.
b=9 and b=-21

Answer:
∠QSR = 78°∠SQR = 51°Step-by-step explanation:
The measure of an inscribed angle (QTR) is half the measure of the arc it intercepts. The measure of an arc is the same as the measure of the central angle it intercepts. So, we have ...
∠QSR = 2×∠QTR
∠QSR = 2×39°
∠QSR = 78°
__
Sides SQ and SR are radii of circle S, so are the same length. That means triangle QRS is an isosceles triangle and the base angles SQR and SRQ are congruent. The sum of angles in a triangle is 180°, so we have ...
∠QSR + 2(∠SQR) = 180°
78° + 2(∠SQR) = 180° . . . . fill in the value we know
2(∠SQR) = 102° . . . . . . . . . subtract 78°
∠SQR = 51° . . . . . . . . . . . . .divide by 2
Kayden is a teacher and takes home 100 papers to grade over the weekend. He can grade at a rate of 6 papers per hour. How many papers would Kayden have remaining to grade after working for 10 hours?
Answer:
40
Step-by-step explanation:
6 * 10 = 60 papers done and complete
100- 60 = 40
Answer:
40 papers will be remaining
Step-by-step explanation:
= As,It take 1 hour to grade 6 papers
= 1 -6
= 10-?
= by cross multiplying we get 60 papers
= 100 - 60
= 40 papers

If the sphere shown above has a radius of 8 units, then what is the approximate volume of the sphere? (Use 3.14 for .)
Answer: 2144
Step-by-step explanation:
v = 4/3pir³
v = 4/3 (3.14) (8)³
v = 4/3 (3.14)(512)
v ≈ 2144
Answer:
2,143.57 cubit units.
Step-by-step explanation:
To find the volume of the sphere, use the formula given below.
Volume = 4/3π r³
Use this formula, the value given for the radius, and 3.14 for to find the volume.
Volume = 4/3π r³
~~ 4/3 (3.14) (8 units)³
~~ 2,143.57 cubic units
Therefore, the approximate volume of the sphere is 2,143.57 cubic units.

PLS HELP ME 12x - 15 = 6 - 3x
Can you pls show me the solving steps and the answer I have to type a paper on how to solve this problem help me plsss (10 points)
Answer:
x= 21/15
if you need to reduce it would be x=7/5
Step-by-step explanation:
12x-15 =6-3x
add 3x to both sides
15x- 15 = 6
now add 15 to both sides
15x = 21
lastly divide both sides by 15
x= 21/15
if you need to reduce it would be x=7/5
Answer:
x = 7/5 or 1.4
Step-by-step explanation:
12x - 15 = 6 - 3x Need to move one variable term to the other side to
+3x + 3x isolate it on one side
---------------------------
15x - 15 = 6 need to +15 to isolate the variable term
+15 +15
-----------------------
15/15x = 21/15 (simplify 21/15 = 7/5) need to divide by 15 to isolate x
------------------------
x = 7/5 or 1.4
