what is the slope of the linear function of (6 , 2) (9 , 8)
Answer:
2
Step-by-step explanation:
To find the slope, we use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 8-2)/(9-6)
=6/3
=2
Answer: The slope of the linear function is 2.
Step-by-step explanation:
We can use the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] to find the slope
[tex]\frac{8-2}{9-6} \\\frac{6}{3} \\2[/tex]
The slope is 2.

FIND VOLUME OF THE PYRAMID pls fast JUST ANSWER DONT EXPLAIN
Answer:
V = 211.56 mm
Step-by-step explanation:
The volume of a pyramid :
V = 1/3(Lenght * width * height)
Length = 9mm
Width = 8.2 mm
Height = 8.6 mm
Hence, we have ;
V = 1/3(9 * 8.2 * 8.6)
V = 1/3 * 634.68
V = 211.56 mm
High population density can cause increases in competition for resources, such as food and shelter. The table shows the number of zebras living in four different regions.
A 3-column table has 4 rows. The first column has entries Region A, Region B, Region C, Region D. The second column is labeled Population of Zebras with entries 1,312, 630, 16,400, 17,800. The third column is labeled Area (kilometers squared) with entries 212, 314, 625, 902.
In which region is competition for resources most likely the greatest?
Region A
Region B
Region C
Region D
Answer:
C
Step-by-step explanation:
magic
The region with the competition for resources is region C with the highest population density
What is Population Density?The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.
Population density = number of people / the area they occupy
Given data ,
Let the population density be represented as P
Region Population Area
A 1,312 212
B 630 314
C 16,400 625
D 17,800 902
Now , the state with the highest population density will have the greater competition for the resources
So , The population density in Region A = 1312 / 212 = 6.19
The population density in Region B = 630 / 314 = 2
The population density in Region C = 16400 / 625 = 26.24
The population density in Region D = 17800 / 902 = 19.7
Hence , the region C has the highest population density

Find the area of the triangle
Answer:
D - 192
Step-by-step explanation:
So the solve this, lets use the formula for area of a triangle:
b*h / 2 = A
b is the base, h is the height.
In this case, our base is 32, and our height is unknown.
To find it we must use pythagreons theorm:
[tex]a^2+b^2=C^2[/tex]
a is half of the base in this case, since tecnically this iscoceles traingle(2 same sides) cut in half is 2 right triangles.
32/2 = 16
b is the unknown, and C is the hypotenuse(longest length) which is 20:
[tex]16^2+b^2=20^2[/tex]
[tex]256*b^2=400[/tex]
[tex]b^2=144[/tex]
[tex]b=12[/tex]
So we know b, whihc is our height, is 12.
Plugging this in:
32*12 / 2 = A
384 / 2 = A
192 = A
So the area of the triangle is 192.
Hope this helps!
Answer:
D: 192 square ft
Step-by-step explanation:
We are given all 3 side lengths of the triangle, and we notice that 2 of the sides are congruent (the 2 sides that are 20 ft). Therefore, we can safley say that this triangle is isosceles. What this tells us is that the height bisects the base. This is important because we can say that the base for each of the right triangles created by the height is 16. From there, we can say that h = 12 because 20 and 16 are basically 4 and 5 multiplied by 4, which means that the side lengths form a scaled-up version of the Pythagorean Triple 3-4-5. Now, just calculate the area by doing [tex]\frac{1}{2}*32*12[/tex] (basically just half * base * height), which gives us 192 [tex]ft^{2}[/tex]. Hope this helps!

Now that you know the height of the cone how can you solve for the slant height?
Answer:
imagine a triangle
one side is just upwards trough the cone, one side is the radius of the circle and the last one is the slant height.
remember the pythagoras stuff
so
(slantheight)² = radius² + height²
or finally:
slantheight = squareroot (radius² + height²)

Sandy went to her local zoo where 50% of it's exhibits featured reptiles. If the zoo features 44 exhibits in total, then how many of the zoo's exhibits feature reptiles?
Answer:
22 exhibits
Step-by-step explanation:
We are told from the above question that:
Sandy went to her local zoo where 50% of it's exhibits featured reptiles.
If the zoo features 44 exhibits in total, then the number of the zoo's exhibits that feature reptiles is calculated as:
50% of 44
50/100 × 44
= 50 × 44/100
= 22
Therefore, the number of the zoo's exhibits that feature reptiles is 22 exhibits.

Answer:
64 × pi m²
Step-by-step explanation:
the formulas needed for the surface area of a cone are :
base area plus the "mantle", the lateral "wall" around it.
the base area is a circle.
so, that formula is Ac = pi×r²
the "wall" formula is Aw = pi×r×s
r = radius
s = slant height = 12
the formula for the surface area of a sphere is
As = 4×pi×r²
we know now, that both surface areas are the same, and also the radius is the same for both objects.
Ac + Aw = As
pi×r² + 12×pi×r = 4×pi×r²
=>
12×pi×r = 3×pi×r²
12×pi = 3×pi×r
12 = 3×r
r = 4 m
now, we only need to use this value of r in our formulas for surface areas, like for the sphere :
4×pi×r² = 4×pi×4² = 4³×pi = 64×pi
F(x) = -x² + 7x - 12
One factor of this is (x - 4). Find the other factor.
Answer:
(3-x) is the other factor.
Step-by-step explanation:
The given function is :
[tex]F(x)=-x^{2}+7x-12[/tex]
One of the factor is (x-4)
We need to find the other factor.
It can be solved as follows :
[tex]F(x)=-x^{2}+4x+3x-12\\\\=(-x+3)(x-4)[/tex]
So, the other factor is (3-x).

You just hung a picture twelve inches above the wall trim. Your friend thinks the
picture looks crooked. Use what you know about parallel lines and transversals to
determine if the picture is level.
Step 1: You don't have a level, but you are in luck. You know the wall trim is level.
You have a protractor and the sun is casting a shadow on the wall. Describe how
you can determine if the picture is level.
: Assume you measured ∠3 and ∠5 and found them to be equal. Use the
spaces provided below to complete a formal proof that demonstrates the picture
is level with the trim.
Answer:
The angles measured between the shadow and the wall trim and the shadow and the top or bottom of the picture should be equal if the picture is level
Step-by-step explanation:
Whereby the picture is 12 inches above the wall trim and the Sun is casting a shadow on the wall, therefore, the edges of the shadow of a straight edged object is straight
If the picture is level, the shadow cast by the sun is transversal to the wall trim and the line formed by extending the bottom or top of the picture in the direction of the shadow. That is, if the picture is parallel, the shadow cast by the Sun on the wall is transversal to the picture and the wall trim if or when the shadow eventually crosses the picture
With the protractor, the angle between the shadow and the wall trim and the shadow and the top or bottom is measured
The angles measured should be the same if the picture is level.

975 toffees are to be distributed among 23 children. Estimate the numbers of toffees that each child will get in nearest tens.
Answer:
40
Step-by-step explanation:
Total number of toffees = 975
Total number of children = 23
Estimate the numbers of toffees that each child will get in nearest tens.
Number of toffees each child get = Total number of toffees / Total number of children
= 975 / 23
= 42.391304347826
Approximately,
Number of toffees each child get = 40 to the nearest tens

Find the exact circumference if the circle has a radius of 12 cm
==========================================================
Explanation:
If the circumference is r = 12 cm, then the diameter is double that at d = 2*r = 2*12 = 24 cm.
This then leads to the circumference of C = pi*d = pi*24 = 24pi
This is exact in terms of pi. Replace pi with something like 3.14 to find its approximate value. The circumference is the distance around the circle's edge, aka perimeter.
