In order to construct the perpendicular bisector of AB, which statement describes the compass settings and the number of arc intersections needed? A less than half the length of AB : 1 B В. less than half the length of AB : 2 more than half the length of AB : 1 O D more than half the length of AB : 2
Answer:
Answer:
D. More than half the length of AB ; 2 intersections needed
Step-by-step explanation:
Bisection implies dividing a given segment or angle into two equal halves.
To bisect AB, open the radius of the compass more than half the length of AB. With center A, describe an arc at the upper region of AB and below AB. Now, using B as the center, draw a second arc upward and downward to intersect the initial arcs at a point. Join the two points of intersection with a line passing through AB. Thus, AB has been bisected.

Zach is saving money to purchase a car. He has already saved $800 in an account. He is going to deposit $75 in the account every week He will not make any withdrawals or any other deposits
Part B
If Zach saves his money for 24 weeks, use your equation to find how much money he will have saved. Show your work and explain your answer. If the answer is correct I will award brainiest.
Answer:
$2600 I believe
Step-by-step explanation:
Since he puts $75 in his account every week and he save his money for 24 weeks, 75 times 24= 1800 and he already had $800 in his account, so 1800+ 800= 2600

Which equations have infinitely many solutions?
Answer:
The 1st, 3rd and 4th
Step-by-step explanation:
Answer:
Options B and D
Step-by-step explanation:
Let's solve each equation:
x-3x=-2x+4
-2x=-2x+4
0=4
No solutions, so A is wrong
x-1/3(3x)=0
x-(3x/3)=0
x-x=0
0=0
Infinitely many solutions, so B is correct
1/3x-3=4+2x
1/3x=7+2x
-5/3x=7
x=-21/5
One solution, so C is incorrect
3x+2-1/3(3x)=2+2x
3x+2-(3x/3)=2+2x
3x+2-x=2+2x
2x+2=2+2x
2x=2x
0=0
Infinitely many solutions, so D is correct
x-1/3x+2=0
2/3x+2=0
2/3x=-2
x=3
One solution, so E is incorrect
As you can see, when both sides of the equations are equal to each other such as 0=0 and x=x, you'll always have infinitely many solutions. Therefore, options B and D are correct

. Qwanell says that the product of n x
(
) is greater than (
)
because
multiplication always increases a number. Which of the following values for
n prove that Qwanell is incorrect? Select all the correct answers
Answer:
both values 0 and 1 will prove that Qwanell is incorrect
Step-by-step explanation:
Regardless of what number n is being multiplied by, both values 0 and 1 will prove that Qwanell is incorrect. That is because 0 will cause the product of the number to be 0 as well which will either decrease or cause the number to be the same if it is multiplied by 0 as well. If a number is multiplied by 1 it will not increase at all, instead it will simply remain the same. Both of which prove that not all products are greater than the numbers being multiplied.

A restaurant chef bought potatoes at four different stores. The table shows the amount of the potatoes she bought at each store and the price she paid. Store Price Pounds Bought $6.60 $3.50 $9.75 $4.80 8 Which store has the lowest price per pound for potatoes?
Answer:
The way to answer this question is to find out the price per pound potato by dividing the amount the restaurant chief paid by the number of pounds bought.
Your question lacks details on the pounds bought in the other stores so I will assume these figures and you can use it as a reference.
Restaurant B - 2 pounds
Restaurant C - 12 pounds
Restaurant D - 5 pounds
Price per pound
Restaurant A = 6.60/8
= $0.83
Restaurant B = 3.50/2
= $1.75
Restaurant C = 9.75/12
= $0.82
Restaurant D = 4.80/8
= $0.96
Restaurant C has the lowest price per pound for potatoes.

Hope it's help you.... ^_^Determine a and k so the given points are on the graph of the function.
(1,18), (2,3); y= a(x + 1)2 +k
Step-by-step explanation:
Explanation:
Because
(2,6) is in the function, we can plug
6 as y
and
2 as x.
From that we get
6=a(2−1)2+k
6=a+k
Same for the next point:
12=a(3−1)2+k
12=22a+k
12=4a+k
Now we have this system of equations to solve:
a+k=6
4a+k=12
Solving it leads to the conclusion that
a=2,k=4 .

Hello!
[tex]\large\boxed{f^{-1} = \frac{5x+2}{4x-2}, f^{-1}(3) = \frac{17}{10} }[/tex]
[tex]f(x) = \frac{2x +2}{4x - 5}[/tex]
Find the inverse by swapping the x and y variables:
[tex]y = \frac{2x +2}{4x - 5}\\\\x = \frac{2y +2}{4y - 5}[/tex]
Begin simplifying. Multiply both sides by 4y - 5:
[tex]x(4y - 5) = 2y + 2[/tex]
Start isolating for y by subtracting 2 from both sides:
[tex]x(4y - 5) -2 = 2y[/tex]
Distribute x:
[tex]4yx - 5x - 2 = 2y[/tex]
Move the term involving y (4yx) over to the other side:
[tex]- 5x - 2 = 2y - 4yx\\\\[/tex]
Factor out y and divide:
[tex]- 5x - 2 = y(2 - 4x)\\\\y = \frac{-5x-2}{-4x+2} \\\\y = \frac{-(5x + 2)}{-(4x - 2)} \\\\y^{-1} = \frac{5x + 2}{4x - 2}[/tex]
Use this equation to evaluate [tex]f^{-1}(3)[/tex]
[tex]f^{-1}(3) = \frac{5(3) + 2}{4(3) - 2} = \frac{17}{10}[/tex]

temperatures displayed while cooking are within a
5% error. Rachel is using the oven to cook a chocolate
cake that must be cooked at a temperature below
325°C. The oven display shows a temperature of 310°C.
Can Rachel be certain that the temperature is suitable
for cooking her cake? Explain your answer.
Result, Rachel can be certain that the temperature is suitable for her cake.
Rachel cannot be certain that the temperature displayed on the oven is suitable for cooking her cake.
The manufacturer's claim of a 5% error on the displayed temperature means that the actual oven temperature can be off by 5% in either direction. To calculate the range of possible actual temperatures, we need to find 5% of 310°C. 5% of 310 = (5/100) * 310 = 15.5°C This means that the oven temperature could be 15.5°C higher or 15.5°C lower than the displayed temperature.
To find the maximum possible temperature, we add the error to the displayed temperature: 310°C + 15.5°C = 325.5°C Since the maximum possible temperature is slightly above 325°C, Rachel cannot be certain that the temperature is suitable for cooking her cake, as it needs to be cooked at a temperature below 325°C. It's important for Rachel to consider using an alternative thermometer or verifying the actual temperature with the oven manufacturer to ensure the cake is cooked at the desired temperature.

The perimeter of a triangle is 108ft. The sides lengths are in a ratio of 2:3:7. How long is the shortest side?
Answer:
18ft
Step-by-step explanation:
2+3+7 = 12 (this means that 108ft is [tex]\frac{12}{12}[/tex])
The shortest side would be [tex]\frac{2}{12}, or \frac{1}{6}[/tex] of 108ft
To find this, we divide 108 by the denominator (6) to get 18ft
We would usually multiply this by the numerator when finding a fraction of an amount, but as the numerator is 1, the answer would stay as 18ft.
Give the slope of any line that is perpendicular to the line y = -1/8 x + 5
Answer:
8
Step-by-step explanation:
To find a slope for a line that is perpendicular to another line, you simply need to take the negative reciprocal of the the original line's slope. In this case we are already given the slope as the coefficient to x: -1/8. The negative reciprocal of that is 8/1, or just 8.
Anybody know the answer
Answer:
x ≈ 10.9
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan38° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{14}[/tex] ( multiply both sides by 14 )
14 × tan38° = x , then
x ≈ 10.9 ( to the nearest tenth )
