Answer:
i believe x=9
Step-by-step explanation:
I took the answer, (28) and subtracted 10 which got me 18. then all I had to do was divide 18 by 2 to get x, which is 9. hope this helps :)
Answer:
x = 9
Step-by-step explanation:
We have: 2x + 10 = 28
Subtract 10 from both sides: 2x = 18
Divide both sides by 2: x = 9

Answer:
-1078
Step-by-step explanation:
To find the nth term in an arithmetic sequence we use the following formula
aₙ=a₁+(n-1)*d
Where a₁ is the first time, and d is the common difference (in this case -20)
So we have
2+(55-1)*-20
2+(54)*-20
2-1080
-1078

Find the Pythagorean Triple (a,b,c) using the terms (x²-y², 2xy, x²+y²) for x > y > 0 when x = 8 and y = 5.
Answer:
(39,80,89)
Step-by-step explanation:
A Pythagorean triple is one that consists of three positive integers a, b and c such that;
a² + b² = c²
In this case;
The terms are: (x²-y², 2xy, x²+y²) where x > y > 0 where x=8 and y=5
The terms are : x²-y² = 8²-5² = 64-25 = 39
: 2xy = 2*8*5 =16*5 = 80
: x²+y²= 8²+5²=64+25 = 89
Applying the Pythagorean triple;
a² + b² = c²
39² + 80² = 89²

A drawing of a surfboard in a catalog shows its length as 8 4 over 9 inches. Find the actual length of the surfboard if 1 half inch length on the drawing corresponds to 3 over 8 foot of actual length. Submit your answer as a fraction using the format, 1 2/3. Do not include units, ft, in your answer.
Answer: [tex]6\dfrac13\text{ inches.}[/tex]
Step-by-step explanation:
Given: Length in drawing = [tex]8\dfrac49\ \text{inches}[/tex]
[tex]=\dfrac{9\times8+4}{9}\text{ inches}\\\\=\dfrac{72+4}{9}\text{ inches}\\\\=\dfrac{76}{9}\text{ inches}[/tex]
Also, half inch on drawing = [tex]\dfrac38\ foot[/tex] actual length.
1 inch on drawing = [tex]2\times\dfrac38 =\dfrac34\ foot[/tex]
[tex]\dfrac{76}{9}\text{ inches}=\dfrac{76}{9}\times\dfrac{3}{4}\ foot\\\\=\dfrac{19}{3}\text{ inches}\\\\=6\dfrac13\text{ inches}[/tex]
The actual length of the surfboard = [tex]6\dfrac13\text{ inches.}[/tex]

what is the exact value of cos(7pi/8)
Answer:
cos ([tex]\frac{7\pi}{8}[/tex]) = [tex]-\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]
Decimal value: −0.9238795325...
Step-by-step explanation:
Write,
cos [tex]\frac{7\pi}{8}[/tex] = cos [tex](\pi-\frac{\pi}{8})[/tex] = −cos [tex]\frac{\pi }{8}[/tex]
Now using half angle formula, cos(x) = 2 cos²([tex]\frac{\pi }{2}[/tex]) − 1, we can write cos [tex]\frac{\pi }{4}[/tex] = 2
cos²([tex]\frac{\pi }{8}[/tex]) − 1
This means [tex]\frac{1}{\sqrt{2}}[/tex] + 1 = 2 cos²([tex]\frac{\pi }{8}[/tex])
2 cos²([tex]\frac{\pi }{8}[/tex]) = [tex]\frac{\sqrt{2}+1}{\sqrt{2}}[/tex]
cos²([tex]\frac{\pi }{8}[/tex]) = [tex]\frac{\sqrt{2}+1}{2\sqrt{2}}[/tex]
cos([tex]\frac{\pi }{8}[/tex]) = [tex]\sqrt{\frac{\sqrt{2}+1}{2\sqrt{2}}}[/tex]
Simplify,
[tex]\sqrt{\frac{\sqrt{2}+1}{2\sqrt{2}}}[/tex] = [tex]\sqrt{\frac{2+\sqrt{2}}{4}[/tex] = [tex]\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]
Hence,
cos ([tex]\frac{7\pi}{8}[/tex]) = −cos ([tex]\frac{\pi }{8}[/tex]) = [tex]-\frac{\sqrt{2+\sqrt{2}}}{2}[/tex]
The exact value of cos(7pi/8) is [tex]\rm -\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex] and this can be determined by using the trigonometric properties.
Given :
Expression -- [tex]\rm cos(\dfrac{7\pi}{8})[/tex]
The following steps can be used to determine the exact value of the given expression:
Step 1 - Write the given expression.
[tex]=\rm cos(\dfrac{7\pi}{8})[/tex]
Step 2 - Rewrite the above expression.
[tex]= \rm cos(\dfrac{8\pi - \pi}{8})[/tex]
Step 3 - The above expression is reduced to:
[tex]= \rm -cos(\dfrac{ \pi}{8})[/tex] --- (1)
Step 4 - According to the trigonometric properties:
[tex]\rm cos(x) = 2 cos^2(\frac{x}{2})-1[/tex]
Step 5 - Substitute the value of x = [tex]\pi[/tex]/4 in the above expression.
[tex]\rm cos(\frac{\pi}{4}) = 2 cos^2(\frac{\pi}{8})-1[/tex]
Step 6 - Simplify the above expression.
[tex]\rm cos(\frac{\pi}{8})=\sqrt{\dfrac{\dfrac{1}{\sqrt{2}} +1}{2}}[/tex]
[tex]\rm cos(\frac{\pi}{8})=\sqrt{\dfrac{1+\sqrt{2} }{2\sqrt{2} }[/tex]
[tex]\rm cos(\frac{\pi}{8})=\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex]
Step 7 - Substitute the value of cos([tex]\pi[/tex]/8) in the expression (1).
[tex]\rm -cos(\frac{\pi}{8})=-\dfrac{\sqrt{2+\sqrt{2}} }{2 }[/tex]

Answer:
m∠J = 85°
Step-by-step explanation:
Angles G and H are congruent to angles Q and R, respectively. The sum of angles in a quadrilateral is 360°, so we have ...
∠J +∠F +∠G +∠H = 360°
∠J +109° +122° +44° = 360°
∠J = 360° -275°
m∠J = 85°

If x+6>2x+4, which of the following is NOT a possible value for x? part 2
"2" is NOT a possible value for x.
The given inequality is:
[tex]x+6>2x+4[/tex]By subtracting "2x" from both sides of the equation, we get
→ [tex]x+6-2x> 2x+4-2x[/tex]
→ [tex]6-x> 4[/tex]
By subtracting "6" form both sides, we get
