What expressions is equivalent to 5 to the power of 8
Answer:
Step-by-step explanation:
5¹⁶ ÷ 5² = 5⁽¹⁶ ⁻ ²⁾ = 5¹⁴ ❌
(5²)⁶ ÷ 5⁴ = 5⁽¹² ⁻⁴⁾ = 5⁸ ✅
5² × 5⁴ = 5⁽²⁺⁴⁾ = 5⁶ ❌
(5⁴)² = 5⁸ ✅
5⁻¹ × 5⁹ = 5⁻¹ ⁺ ⁹ = 5⁸ ✅
5⁻¹ × 5⁻⁸ = 5⁻¹ ⁺ ⁽⁻⁸⁾ = 5⁻⁹ ❌
A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8
y = -6x + 20
Explain why the work is not correct.
Answer:
The student should subtract 8 from each side not add 8
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y - -8 = -6(x -2)
y+8 = -6(x-2)
Distribute
y+8 = -6x+12
Subtract 8 from each side
y+8-8 = -6x+12-8
y = -6x+4
The student should subtract 8 from each side not add 8
Answer:
y -(-8) = -6(x - 2)
y -(-8) = -6x + 12
y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side
y = -6x + 20
the correct equation would be : y= -6x+4
Solve for y.
7v + 25 = 5(v + 7)
Simplify your answer as much as possible.
Answer:
v = 5
Step-by-step explanation:
Distribute on the left:
5 ( v + 7 )
( 5 x v ) + ( 5 x 7 )
5v + 35
7v + 25 = 5v + 35
Subtract 5v from each side:
2v + 25 = 35
subtract 25 from each side:
2v = 10
Divide each side by 2:
v = 5

One angle be x
other is 2x-6ATQ
[tex]\\ \sf\longmapsto x+2x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x-6=90[/tex]
[tex]\\ \sf\longmapsto 3x=96[/tex]
[tex]\\ \sf\longmapsto x=32[/tex]
[tex]\\ \sf\longmapsto 2x-6=2(32)-6=58°[/tex]
Answer:
58°
Step-by-step explanation:
The measure if one 2 complementary angle is 6 less than the measure of the other => x + 2x - 6° = 90°
x + 2x - 6° = 90°
3x = 90° + 6°
3x = 96°
x = 96° : 3
x = 32°
Substitution :
2x - 6°
= 2 × 32° - 6°
= 64° - 6°
= 58°
Divide and round to the nearest tenth: 89.05 divided by 0.41
Answer:
217.2
Step-by-step explanation:
You divide the two numbers. The tenths place is the number after the decimal. The answer without rounding is 217.19(other numbers). 9 raises 1 up to 2 so that's why the answer is 217.2.
What is the 6th term in the sequence below?
4,-8, 16, -32,
Answer:
−128
Step-by-step explanation:
Assuming the pattern continues...
Answer:
[tex]128[/tex]
Step-by-step explanation:
We see that this is a geometric series with common ratio [tex]-2[/tex].
So, the 6th term is the 4th term times [tex](-2)^2=2^2=4[/tex].
So, the answer is [tex]4(-32)=\boxed{128}[/tex] and we're done!
Note:
The closed form for this geometric series is [tex]4*(-2)^{n-1}[/tex], which means the nth term is always [tex]4*(-2)^{n-1}[/tex].

A train leaves Zurich at 2240 and arrives in Vienna at 07 32 the next day. Work out the time taken.
The answer is 8 hours 32 minutes
But can someone properly explain how
Step-by-step explanation:
Okay so, 22:40 is 10:40pm
07:32 is am
Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)
Then there would be 8 hours alone (11 to 7 is 8 hours)
So it takes 8 hours and 52 minutes from 10:40pm to 7:32am

pamelia is 9 years younger than jiri. The sum of their ages is 55. What is Jiris age?
Answer: 32
Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).

Please answer this question correctly, and include work within your answer.
Answer: 11.9 and 12.5
Step-by-step explanation:
|x - 12.2| = 0.3 is telling us that x must be either 12.2 + 0.3 or 12.2 - 0.3.
Longest is (12.2 + 0.3) = 12.5
Shortest is (12.2 - 0.3) = 11.9
