Answers
Answer:
y = 3x - 2
Step-by-step explanation:
See the attached worksheet. Look for an equation of the form y=mx+b, where m is the slope and b is the y-intercept. The slope of the line can be determined by taking two points on the line to calculate the Rise/Run. The points selected for this example are (0,-2) and (2,4). This makes the Rise/Run (6/2), or 3. The y-intercept, b, is -2 as per point (0,-2).
The equation for this (non)-prependicular line is thus y = 3x - 2.

Please help!
Answers
=======================================================
Explanation:
Let's go through the answer choices one by one to see which are true, and which are false.
Choice A) This is true because as we approach x = 2 from the left hand side, the y values get closer to y = 1 from the top Choice B) This is true. As we get closer to x = 4 on the left side, the blue curve is heading downward forever toward negative infinity. So this is what y is approaching when x approaches 4 from the left side.Choice C) This is true also. The function is continuous at x = -3 due to no gaps or holes at this location, so that means its limit here is equal to the function value. Choice D) This is false. The limit does exist and we find it by approaching x = -4 from either side, and we'll find that the y values are approaching y = -2. In contrast, the limit at x = 2 does not exist because we approach two different y values when we approach x = 2 from the left and right sides (approach x = 2 from the left and you get closer to y = 1; approach x = 2 from the right and you get closer to y = -2). So again, the limit does exist at x = -4; however, the function is not continuous here because its limiting value differs from its function value.Choice E) This is true because the function curve approaches the same y value from either side of x = 6. Therefore, the limit at x = 6 exists.Write a situation to describe the equation below:

The capacity of a teaspoon is 0.015 L. How many teaspoons of oil are there in 1.2 L? Please help .
Answers
Answer:
80 teaspoons
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Teaspoon capacity = 0.015 L
Total quantity = 1.2L
So, we can calculate the number of teaspoons in 1.2L oil by using following formula,
Number of teaspoons = Total quantity ÷ Teaspoon capacity
By putting the value of following, we get
Number of teaspoons = 1.2 ÷ 0.015
= 80 teaspoons
Hence, there are 80 teaspoons of oil in 1.2L.
What two angles measure 90 degrees?
Answers
The two angles measure 90 degrees are called as complementary angles.
What are complementary angles?
In geometry, complementary angles are defined as two angles whose sum is 90 degrees.
The two angles' complement and supplement are determined by the sum of their measurements. The two angles are said to be complimentary if their combined measurement equals that of a straight angle.
In other words, a right angle results from the combination of two complimentary angles (90 degrees). Angles 1 and 2 are said to be complementary if their sum of angles equals 90 degrees (i.e., 1 + 2 = 90°), and as a result, they are referred to as each other's partners.
two angles that add up to 90 degrees are known as complementary angles. For example, 60° and 30°.

Answers
=Mr.Lehmans hourly rate for labor is 20$
=30+40=70-50=20
Answer:
The Answer is 15$
You'd need to get the slope
it tells us how he charges with respect to Time
So picking any Point on the graph. Let's say (0,10) and (2,40)
m(slope) = y2-y1/x2-x1
= 40-10/2-0
=30/2
= 15$

(10, −11)

Answers
Answer:
y=4/5x-3 - (-5, -7)
Step-by-step explanation:
So to solve this, lets just plug in each value for x, and see if the y value we get is equal to one of our answers.
So we have (-10, 5)
Well plug in -10 for 4/5x we get:
-40/5=-8
Next we take that value and solve:
y=-8-3
y=-11
The answer for this was 5, not -11.
Ill skip a few steps:
(10, -11):
Plug in 10 we get:
y=8-3 which is y=5. This is not right, for it needed to be -11.
Next we have (5, -1)
This gets us y=4-3 this is y=1 which is not -1. So thats not right.
Finally we have (-5, -7):
This gets us y=-4-3 this is y=-7. What was our y value? -7!
So the answer is (-5, -7)

What is the radius of a hemisphere with a volume of 38153 in”, to the nearest tenth

Answers

26.3
Step-by-step explanation:
Delta Math
The radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].
What is radius?A circle's or sphere's radius is any line segment that connects the object's centre to its perimeter in classical geometry; in more contemporary usage, it is also the length of those line segments.
The word "radius" is derived from the Latin word "radius," which also refers to the spoke of a chariot wheel. Use the equation [tex]r =\frac{D}{2}[/tex] to determine the radius, which is equal to half the diameter. This is the same process used to determine a circle's radius from its diameter.
A hemisphere's volume is equal to [tex]\frac{2}{3} \pi r^3[/tex] cubic units. Where is an estimated constant with a value of [tex]3.14[/tex]. The hemisphere's radius is denoted by "r."
Required calculations are:
V = r
r = radius.
Given, V = 38153 in³
[tex]38153 = \frac{2}{3} \pi r^3[/tex]
[tex]r^3 = \frac{3 \times 38153}{2 \times \pi }[/tex]
[tex]r = 3\sqrt{\frac{3 \times 38153}{2 \times \pi }}[/tex]
r =26.3 in
Therefore, the radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

Eva is going to invest in an account paying an interest rate of 6.1% compounded continuously. How much would Eva need to invest, to the nearest ten dollars, for the value of the account to reach $71,000 in 7 years?
The answer is 46320
Answers
Answer:
$46,320
Step-by-step explanation:
Given that
The rate of interest is 6.1%
The amount is $71,000
And, the time period is 7 years
We need to find out the invested amount
As we know that
In the compounded continously, the following formula should be used
Amount = Invested amount × e^(rate × time period)
$71,000 = Invested amount × e^(6.1% × 7)
$71,000 = Invested amount × e^0.427
$71,000 = Invested amount × 1.5326
So, the investment amount is
= $71,000 ÷ 1.5326
= $46324,912
= $46,320
what is the perimiter of this 1/4 circle
A. 7.85in
B. 12.9in
C. 17.9in
D. 31.4in
Answers
===========================================================
Explanation:
A full circle of radius 5 inches would have a perimeter or circumference of...
C = 2*pi*r
C = 2*3.14*5
C = 31.4
This value is approximate because pi = 3.14 is approximate.
The distance around a full circle with radius 5 inches is roughly 31.4 inches, but we only want a quarter of this. Therefore, the distance around the curved portion of the quarter circle is roughly C/4 = (31.4)/4 = 7.85 inches.
Choice A would be the answer if your teacher only cared about the curved portion. However, don't forget about the straight line portions that also make up the quarter circle. Choice A might have been put there as a trick answer.
We'll add on the two copies of the radius 5 inches to get a total perimeter of 5+5+7.85 = 10+7.85 = 17.85 = 17.9 inches, which points to choice C as the answer.
---------------
Side note:
If we used a more accurate version of pi, say the version stored in your calculator, then the perimeter is roughly
5+5+(2*pi*5)/4 = 17.8539816339744
Rounding to the nearest tenth leads to the same answer of 17.9 inches
