Answer:
[tex]\frac{1}{64}[/tex]
Step-by-step explanation:
(1/8)^2 is actually just (1/8)*(1/8)
We multiple the numerators, 1*1, to get 1,
And the denominators, 8*8, to get 64
So the anwser is (1/64)

The diagram represents a rectangular garden of length 14 m and width 10 m. The flower bed is a triangle and the vegetable patch is a trapezium. The rest of the garden is lawn. Work out the are of the lawn.
Answer:
The area of the lawn is 68 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of lawn = Area of garden - (Area of triangle + Area of trapezium)
Area of garden = length x width
= 14 x 10
= 140 [tex]m^{2}[/tex]
Area of triangle = [tex]\frac{1}{2}[/tex] x base x height
= [tex]\frac{1}{2}[/tex] x 3 x 8
= 12 [tex]m^{2}[/tex]
Area of trapezium = [tex]\frac{1}{2}[/tex] (a + b) h
= [tex]\frac{1}{2}[/tex](5 + 7) 10
= 60 [tex]m^{2}[/tex]
So that;
Area of lawn = 140 - (12 + 60)
= 140 - 72
= 68 [tex]m^{2}[/tex]
The area of the lawn is 68 [tex]m^{2}[/tex].
solve the inequality 31< 3x+4
Answer:
The solution of the given inequality x>9
Step-by-step explanation:
Explanation:-
Given that the inequality 31 < 3 x + 4
Subtracting '4' on both sides, we get
31 - 4 < 3 x + 4 -4
⇒ 2 7 < 3 x
Dividing '3' on both sides, we get
⇒ 9 < x
x > 9

Given the equation y = -3x + 1/2 , what is the y-intercept? -3 3 1/2 -1/2
============================================
Explanation:
The given equation y = -3x+1/2 is in slope intercept form y = mx+b
We match the terms to find that m = -3 is the slope and b = 1/2 is the y intercept.
The y intercept is where the graph crosses the vertical y axis.
Which of the following statements is true?
n = m
n = 4m
- (0,0) is a solution to n=m and to n=4m
- No point on the line n=m is also on the line n=4m
-The graph of the solution is parallel lines
-Every solution to n=m is also a solution to n=4m
Answer:
(0,0) is a solution to n=m and n=4m
Step-by-step explanation:
For the first equation, If u insert 0 as m into n=m
n=(0) then n will equal 0.
For the second equation, if u insert 0 as m in n=4m
n=4(0) then n will also equal 0.
So the answer is (0,0) is a solution to n=m and to n=4m
Hope this helps :)

What is the exact value of x? 5⋅21^5x=16
Answer:
x= 16 /20420505
Step-by-step explanation:
Let's solve your equation step-by-step.
5(215)x=16
Step 1: Simplify both sides of the equation.
20420505x=16
Step 2: Divide both sides by 20420505.
20420505x /20420505 = 16 /20420505
x= 16 /20420505
6. A rectangular piece of land measures 0.7 km by
of wire. What length of wire is needed ?
0.5 km. Each side is to be fenced with four rounds
Answer:
9.6km / 9600m
Step-by-step explanation
B= 0.5km
L = 0.7km
perimeter of a rectangle = 2(L+B)
= 2( 0.7 + 0.5)
= 2.4km
wire for one round is 2.4km
wire for 4 rounds = 2.4 x 4
= 9.6km wire is required.
Hence, 9.6km wire is required to fence the rectangular piece of land 4 times.
Find the locus of a point such that the sum of its distance from the point ( 0 , 2 ) and ( 0 , -2 ) is 6.
~Thanks in advance !
Answer:
[tex]\displaystyle \frac{x^2}{5}+\frac{y^2}{9}=1[/tex]
Step-by-step explanation:
We want to find the locus of a point such that the sum of the distance from any point P on the locus to (0, 2) and (0, -2) is 6.
First, we will need the distance formula, given by:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Let the point on the locus be P(x, y).
So, the distance from P to (0, 2) will be:
[tex]\begin{aligned} d_1&=\sqrt{(x-0)^2+(y-2)^2}\\\\ &=\sqrt{x^2+(y-2)^2}\end{aligned}[/tex]
And, the distance from P to (0, -2) will be:
[tex]\displaystyle \begin{aligned} d_2&=\sqrt{(x-0)^2+(y-(-2))^2}\\\\ &=\sqrt{x^2+(y+2)^2}\end{aligned}[/tex]
So sum of the two distances must be 6. Therefore:
[tex]d_1+d_2=6[/tex]
Now, by substitution:
[tex](\sqrt{x^2+(y-2)^2})+(\sqrt{x^2+(y+2)^2})=6[/tex]
Simplify. We can subtract the second term from the left:
[tex]\sqrt{x^2+(y-2)^2}=6-\sqrt{x^2+(y+2)^2}[/tex]
Square both sides:
[tex](x^2+(y-2)^2)=36-12\sqrt{x^2+(y+2)^2}+(x^2+(y+2)^2)[/tex]
We can cancel the x² terms and continue squaring:
[tex]y^2-4y+4=36-12\sqrt{x^2+(y+2)^2}+y^2+4y+4[/tex]
We can cancel the y² and 4 from both sides. We can also subtract 4y from both sides. This leaves us with:
[tex]-8y=36-12\sqrt{x^2+(y+2)^2}[/tex]
We can divide both sides by -4:
[tex]2y=-9+3\sqrt{x^2+(y+2)^2}[/tex]
Adding 9 to both sides yields:
[tex]2y+9=3\sqrt{x^2+(y+2)^2}[/tex]
And, we will square both sides one final time.
[tex]4y^2+36y+81=9(x^2+(y^2+4y+4))[/tex]
Distribute:
[tex]4y^2+36y+81=9x^2+9y^2+36y+36[/tex]
The 36y will cancel. So:
[tex]4y^2+81=9x^2+9y^2+36[/tex]
Subtracting 4y² and 36 from both sides yields:
[tex]9x^2+5y^2=45[/tex]
And dividing both sides by 45 produces:
[tex]\displaystyle \frac{x^2}{5}+\frac{y^2}{9}=1[/tex]
Therefore, the equation for the locus of a point such that the sum of its distance to (0, 2) and (0, -2) is 6 is given by a vertical ellipse with a major axis length of 3 and a minor axis length of √5, centered on the origin.

A player in a board game rolls a six-sided
number cube labeled 1 through 6 once.
Determine the theoretical probability of
rolling a 1 or 2.
Answer:
A six sided number from 1 to 6 is rolled in a game.
Step-by-step explanation:
Theoretical probability of rolling a 1 or 2.
1) The cube has 6 faces so the total number of the outcome would be 6 only.
2) As per the question we need only 1 or 2 so the favorable outcome would be 2.
3) P(E) = favorable outcome/ total number of outcome
P(E) = 2/6
P(E) = 1/3
Theoretical probability of rolling a 1 or 2 is 1/3

1. y=-6x+3/4
2.y=6x+3/4
3. y=-3/4x+6
4. y=3/4x+6
Answer:
3. y=-3/4+6
Step-by-step explanation:
The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.
Answer:
y=-3/4x+6
Step-by-step explanation:
the y/intercept is (0,6) because that is the point where the line crosses the y-axis
knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4
using the slope intercept equation y=mx+b it is y= -3/4+6
it is negative because its going downward
hope this makes sense and helps you guys!

Write an equation of the line that passes through (2, −1) and is parallel to the line y=−3x+8.
An equation of the parallel line is y=
Answer:
Step-by-step explanation:
The slope of the line in question is the same as the slope of the line parallel to it. Using y = mx + b, where m is the slope, we find the slope of our line is -3.
Using the pt-slope form, y - y1 = m( x - x1), we get y - (-1) = -3( x - 2) or y + 1 = -3x + 6. Which leads us to y = -3x + 5. QED
