Find the slope of the line passing through (-2 , 1) and (1,1)
Answer:
The slope of the line is: M = 0
Step-by-step explanation:
Using the "Slope from 2 points" formula which is \/
M = (y2 - y1) / (x2 - x1)
We just need to input the numbers to find the slope!
M = ( 1 - 1 ) / (1 - - 2 )
Now solve within the parentheses:
M = ( 0 ) / ( 3 )
Which is basically just 0.
I hope the formula: M = ( y2 - y1) / (x2 - x1)

Helen needs a replacement ball bearing for this part. The surface area of each spherical ball bearing is approximately 452.16 square milimeters.
What is the radius of the bearing that Helen needs to buy? Round your answer to a whole number
Using the surface area of the sphere, it is found that the radius of the bearing that Helen needs to buy is of 6 millimeters.
What is the surface area of a sphere?The surface area of a sphere of radius r is given by:
[tex]S_A = 4\pi r^2[/tex]
In this problem, we have that:
[tex]S_A = 452.16[/tex]
Hence:
[tex]4\pi r^2 = 452.16[/tex]
[tex]r = \sqrt{\frac{452.16}{4\pi}}[/tex]
r = 6.

Find the center and radius of the circle represented by the equation below.
Answer:
Center= (-6,-8)
Radius= 6
Step-by-step explanation:
We use the formula (x-h)^2+(y-k)^2 then plug in our numbers:
[tex](x - h)^2 + (y - k)^2 = r^2\\(x+6)^2 +(y-k)^2=36[/tex]
In the equation -h is 6 so our h (x-coordinate) is -6
In the equation -k is 8 so our k (y-coordinate) is -8
In the equation r^2 is 36 so we take the square root of 36 to get r which is 6.

An airplane is ascending at a constant rate of 15 feet per second what is the change in altitude during 10 minutes of flight
Answer:
9000 ft
Step-by-step explanation:
Given: A airplane is ascending at a constant rate of 15 feet per second,
What we need to know: The change in altitude during 10 minutes of flight,
60 seconds = 1 minute
60 × 10
= 600 seconds
600 × 15
= 9000 ft
Therefore there was a 9000 ft change in altitude during the 10 minutes of the flight.

Does anybody know this?Two complementary angles are in the ratio of 4:6 find the measure of the smallest angle and the value of x.
Answer:
36
Step-by-step explanation:
A ratio 4:6 means the one quantity is 4/10 of the full thing:
While the other quantity is 6/10 of the full thing
So the smaller angle will be 4/10 of the the complementary angle.
Complementary angle is 90.
So 4/10 of 90 is 36.

•
It increased
It decreased
It stayed the same
It matched inflation
The purchasing power of Sandra's savings according to the description above has decreased.
What happens to the purchasing power of Sandra's savings?It follows from the task content that Sandra's savings attracted an annual interest rate of 1% while the inflation is 2% per annum. On this note, it follows that Sandra's savings purchasing power has reduced as the prices of commodities have gone up and the interest rate is unable to match it.

The angle ∠DEF is equal to 90 degrees. Then the triangle ΔDEF will be a right-angle triangle.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.
The angle ∠DEG = 51° and angle ∠GEF = 39°.
Then prove that the triangle ΔDEF will be a right-angle triangle. Then we have
We know that if one angle of the triangle is 90 degrees then the triangle will be named a right-angle triangle.
The sum of the angle ∠DEG and ∠GEF will be
∠DEF = ∠DEG + ∠GEF
∠DEF = 51° + 39°
∠DEF = 90°
Then the triangle ΔDEF will be a right-angle triangle.

We have a circle with center K with an arc HJ with a measure of 40°. What is the measure of angle HIJ?
40°
60°
80°
20°
The measure of angle HIJ is 20°. The correct option is the last option 20°
Circle GeometryFrom the question, we are to determine the measure of angle HIJ
From one of the Circle theorems, we have that
The angle at the center of a circle is twice the angle at any part of the circumference
From the information,
The measure of arc HJ is 40°. That is, the angle at the center is 40°.
Then, using the above theorem,
Measure of angle HIJ = 40° / 2
Measure of angle HIJ = 20°
Hence, the measure of angle HIJ is 20°. The correct option is the last option 20°

On a coordinate plane, point F is located at points 3, 7 and point G is located at points 9,7. whats the distance in units between point F and point G? Enter the answer in the box.
Answer:
6 units
Step-by-step explanation:
since the y- coordinates of both points are 7 then the horizontal distance between the points is the absolute value of the difference in the x- coordinates , that is
d = | 9 - 3 | = | 6 | = 6 units , or
d = | 3 - 9 | = | - 6 | = 6 units
