Answer:
[tex] {b}^{41} [/tex]
Step-by-step explanation:
1. Use power rule.
[tex] {b}^{21} ( {b}^{4} ) {}^{5} [/tex]
2. Use the power of rule again.
[tex] {b}^{21} {b}^{20} [/tex]
3. Use product rule.
[tex] {b}^{21} + 20[/tex]
4. simplify.
[tex] {b}^{41} [/tex]
Therefor, the answer is
[tex] {b}^{41} [/tex]
Two lines, A and B, are represented by the following equations:
Line A: y = x − 1
Line B: y = −3x + 11
Which of the following options shows the solution to the system of equations and explains why? (4 points)
a
(3, 2), because the point does not lie on any axis
b
(3, 2), because one of the lines passes through this point
c
(3, 2), because the point lies between the two axes
d
(3, 2), because both lines pass through this point
Answer:
The solution to the system of equations is (3, 2) and because both lines pass through this point.
Hence, option D is correct.
Step-by-step explanation:
Given the system of equations
Line A: y = x − 1
Line B: y = −3x + 11
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-x=-1\\ y+3x=11\end{bmatrix}[/tex]
subtracting the equations
[tex]y+3x=11[/tex]
[tex]-[/tex]
[tex]\underline{y-x=-1}[/tex]
[tex]4x=12[/tex]
solving 4x = 12 for x
[tex]4x = 12[/tex]
divide both sides by 4
[tex]\frac{4x}{4}=\frac{12}{4}[/tex]
Simplify
[tex]x = 3[/tex]
For y = x − 1, substutute x = 3
y = x-1
y = 3 - 1
y = 2
Thus,
(x, y) = (3, 2)
Therefore,
The solution to the system of equations is (3, 2) and because both lines pass through this point.
Hence, option D is correct.

d is correct

2.) Solve:
-24 - 2m = -4m - 8(m + 8)
Answer:
m = -4
Step-by-step explanation:
First, you should distribute -8 into m + 8 to get -8m - 64. Then, you should combine -4m and -8m together to get -12m as a result. Your equation should now be -24 - 2m = -12m - 64. Add 12 on both sides to get -24 + 10m = -64. Add 24 on both sides to get -40 on the right side. Finally, divide 10 on both sides to get your m value which is -4.
Answer:
-4
Step-by-step explanation:
-24 - 2m = -4m - 8(m + 8) (Remove the parentheses)
-24 - 2m = -4m - 8m - 64 (Collect like terms)
-24 - 2m = -12m - 64 (Move the term)
-2m + 12m = -64 + 24 (Collect like terms, Calculate)
10m = -40 (Divide both sides)
m = -4

What is the equation of a line that has a slope of -3, and passes through the point (-4,8)
Answer:
y = -3x - 4
Step-by-step explanation:
[tex]\frac{8-y}{-4-x} = \frac{-3}{1}[/tex]
[tex]y = 11\\x = -5[/tex]
(-5,111)
y = -3x + b
8 = -3(-4) + b
8 = 12 + b
b = -4
y = -3x - 4
If in a parallelogram, its diagonals bisect each other right angle and are
equal, then it is a
(a)Square (b)Rectangle (c)Rhombus (d)Kite
Answer:
The parallelogram is a "Square" ⇒ (a)
Step-by-step explanation:
In a parallelogram
Every two opposite sides are parallelEvery two opposite sides are equalEvery two opposite angles are equalIts diagonals bisect each otherIf the diagonals of a parallelogram are equal, then it is a rectangleIf the diagonals of a parallelogram are perpendicular to each other, then it is a rhombusIf the diagonals of a parallelogram are equal and perpendicular, then it is a square∵ In a parallelogram, its diagonals bisect each other at right angles
∴ Its diagonals are perpendicular
∵ Its diagonals are equal
→ By using rule 3 above
∴ The parallelogram is a square

What is the radius of a cylinder with a volume of 1650
cubic feet and a height of 10 feet?
Answer:
The radius of cylinder = 7.428 feet
Step-by-step explanation:
Volume of cylinder = 1650 cubic feet
Height = 10 feet
We need to find radius of cylinder
The formula used is: [tex]Volume=\pi r^2h[/tex]
Putting values and finding radius
[tex]Volume=\pi r^2h\\1650=3.14\times r^2 \times 10\\1650=31.4\times r^2\\r^2=\frac{1650}{31.4}\\r^2=52.547\\Now,\:taking\:square\:root\:on\:both\:sides\\\sqrt{r^2}=\sqrt{52.547}\\r= 7.248\:feet[/tex]
So, the radius of cylinder = 7.428 feet
