Answer:
The equation of the line is;
y = 0.8x + 1
Step-by-step explanation:
Here, we want to get the equation of the line
The general equation of a straight line is;
y = mx + b
m
is the slope and b is the y-intercept
The y-intercept is simply the point on the y-axis where the line crosses the y-axis
we have this point at (0,1)
so we have;
y = mx + 1
to get m, we get any other point on the line and substitute its coordinates before we solve for m
we can identify the point (-2.5, -1)
substituting the coordinates
-1 = -2.5(m) + 1
-2.5m = -1-1
-2.5m = -2
m= 2/2.5
m= 0.8
so we have the equation of the line as;
y = 0.8x + 1

Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial.
24f2+11
Answers
Answer:
24t^2 + 11
Step-by-step explanation:
There is a lot left out of this question. If you are allowed rational numbers, a common factor could be 24.
24(t^2 + 11/24) is one possibility.
I think what you mean is there an integer that is a common factor. There is not.
So the answer is 24t^2 + 11
There is one more thing that needs to be clarified. Can you give t a value? If you can, then t = 11
the common factor would be
11(24 * 11 + 1)
I doubt very much that this is what is meant, but the question really should make it clear.
Answer:
1(24f²+11) is your answer
Step-by-step explanation:

Maggie is rock climbing. After reaching the summit, she descends 14 feet in 213 1 3 minutes. If she continues at this rate, where will Maggie be in relation to the summit after 8 minutes?
Answers
Answer:
48 feets
Step-by-step explanation:
Given that:
Maggie descends 14 feets in 2 1/3 minutes
14 feets takes 7/3 minutes
The amount of feets she descends after 8 minutes will be x ;
14 = 7/3
x = 8
Cross multiply
7/3 * x = 14 * 8
7x /3 = 112
7x = 112 * 3
7x = 336
x = 336 / 7
x = 48 feets
Find the Are of the Shaded Region
Answers
= 3/4 x 22/7 x 6²
= 84.86cm²
That should be the correct answer
Hope this helps!!
Answer:
≈ 84.8 cm²
Step-by-step explanation:
The area of the shaded region is calculated as
area of circle - area of unshaded sector
area of circle = πr² = π × 6² = 36π
unshaded area = area of circle × fraction of circle
= 36π × [tex]\frac{90}{360}[/tex] = 36π × [tex]\frac{1}{4}[/tex] = 9π
area of shaded region = 36π - 9π = 27π ≈ 84.8 cm² ( nearest tenth )
What is the distance between the points (-5, 9) and (4, 9) on the coordinate plane? 9 9 1 1 10 10 90
Answers
Answer:
9 units
Step-by-step explanation:
Given: Two points on a coordinate plane are [tex](-5,9),\,(4,9)[/tex]
To find: distance between points [tex](-5,9),\,(4,9)[/tex]
Solution:
According to the distance formula,
Distance between points [tex](a,b)[/tex] and [tex](c,d)[/tex] is equal to [tex]\sqrt{(c-a)^2+(d-b)^2}[/tex]
Take [tex](a,b)=(-5,9),\,(c,d)=(4,9)[/tex]
Therefore,
Distance between points [tex](-5,9),\,(4,9)[/tex] [tex]=\sqrt{(4+5)^2+(9-9)^2}[/tex]
[tex]=\sqrt{(9)^2}[/tex]
[tex]=9[/tex] units

Answers
Answer:
(s - 1)(s² + s + 1)
Step-by-step explanation:
s³ - 1 ← is a difference of cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
s³ - 1
= s³ - 1³
= (s - 1)(s² + s + 1)
The required factorized form of the given expression is (s - 1)(s² + s + 1).
What is the Factorization?Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).
We have been given that the expression below as
s³ - 1
We have to determine the factor of the given expression
As per the question, we have
s³ - 1
This is a difference between cubes and factors in general as
a³ - b³ = (a - b)(a² + ab + b²) , then
⇒ s³ - 1 = s³ - 1³
⇒ (s - 1)(s² + s + 1)
Thus, the required factorized form is (s - 1)(s² + s + 1).

Step-by-step explanation:
The x-coordinate of the midpoint of the line segment connecting (8, 1) and (-2, -5) is -2 plus half the horizontal distance from -2 to 8, which is 10, or 5. We add 5 to -2, obtaining 3 units.
The y-coordinate of the midpoint is found similarly. The vertical distance between the two given points is 1 - (-5), or 6 units. Half of that is 3 units. Adding 3 units to -5 yields -2.
The midpoint is (3, -2).
Thus, the coordinates of the midpoint at (-7, 6)

Answers
Answer:
7.5
Step-by-step explanation:
The height of the cylinder is equal to 7.5 meters.
Given that,
An oblique cylinder has a volume of 90π m ^3 and a base area of 12π m^2.
A cylinder is defined as it is geometric shape when a rectangle sheet fold into a circular shape the figure arises looks same as the tube structure.
What is volume?Volume, is defined as the ratio of the mass of object to its density.
The volume of the oblique cylinder = height * base area
90π = 12π * height
height = 7.5 m
Hence, the height of the cylinder is equal to 7.5 meters.
