P = 6 + 6.4 + 13 + 12.8 = 38.2 unitsis this a function graph?
Answer:
No, this is a relation
Step-by-step explanation:
You can do a vertical line test to see if a function is actually a function or not. Simply draw vertical lines over the graph
If the x-value has 2 or more y values then it is NOT A FUNCTION
Answer:
No! This is not a function.
Step-by-step explanation:
If you write a vertical line through the graph, it will cross through it twice. That means it's NOT a function graph.

The greater of two consecutive EVEN numbers is 40 less than twice the smaller number. Find the larger number
Answer:
44Step-by-step explanation:
z - some integer
2z - first given even integer (the smaller one)
2z+2 - even integer consecutive to 2z (the larger one)
2(2z) - twice the smaller number
2(2z) - 40 - the number 40 less than twice the smaller number
2(2z) - 40 = 2z + 2
4z - 40 = 2z + 2
2z = 42
2z+2 = 42+2 = 44
check:
2(2z)-40 = 2(42)-40 = 84-40 = 44
solve for k. k/2 +1/2=3
Answer:
[tex]k = 5[/tex]
Step-by-step explanation:
Solve for [tex]k[/tex] :
[tex]\frac{k}{2} + \frac{1}{2} = 3[/tex]
-Multiply both sides of the equation by the denominator [tex]2[/tex] :
[tex]2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2[/tex]
[tex]k + 1 = 6[/tex]
-Subtract both sides by [tex]1[/tex]:
[tex]k + 1 - 1 = 6 - 1[/tex]
[tex]k = 5[/tex]
So, the value of [tex]k[/tex] is [tex]5[/tex].

which statement describes the meaning of the point (010) on the graph?
A After 10 hours there are 10.000 bacteria.
B. After 10 hours there are no more bacteria
C The population began with 10,000 bacteria
D. The population is multiplying itself by 10 each hour
Answer:
Option (C)
Step-by-step explanation:
From the graph attached in the picture,
Graph shows the relationship between time and the population of a culture of bacteria.
Option (A).
After 10 hours there are 10000 bacteria.
Since, at t = 0, number of bacteria = 10000.
False.
Option (B).
After 10 hours there are no more bacteria.
Since, from the given graph bacteria population is increasing exponentially every hour.
Therefore, from t = 0, where the population was 10000, bacteria will be much more in the numbers.
False.
Option (C).
The population began with 10000 bacteria.
True.
Option (D).
The population is multiplying itself by 10 each hour.
Since, growth is exponential therefore, bacteria population is growing faster.
False.
Option (C) is the answer.

a pile of sand has a weight of 90 kg the sand is put into a small bag a medium bag and a large bag in the ratio 2:3:7
work out the wight of sand in each bag
Answer:
15 kg, 22.5 kg, 52.5 kg
Step-by-step explanation:
Let the common multiplier of the given ratios be x. Therefore, weights of each bag would be 2x, 3x and 7x
According to the given information:
[tex]2x + 3x + 7x = 90 \\ 12x = 90 \\ x = \frac{90}{12} \\ x = 7.5 \: \\ \implies \\ 2x = 2 \times 7.5 = 15 \: kg \\ 3x = 3 \times 7.5 = 22.5 \: kg \\ 7x = 7 \times 7.5 = 52.5 \: kg[/tex]
Hence the weight of sand in bag would be 15 kg, 22.5 kg and 52.5 kg

Given the points below, find XY. Round to
the nearest hundredth.
X(-8, 2) and Y(7,-4)
Answer: 16.16
Step-by-step explanation:
xy in this situation, will be the distance between the two points.
(-8,2) (7,-4) Find the distance between the points
To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.
2-(-4) = 6
-8 - 7 = -15
6^2 + (-15)^2 = d^2 where d is the distance
36 + 225 = d^2
261 = d^2
d= [tex]\sqrt{261}[/tex]
d= 16.1554 rounded to the nearest hundredth is 16.16
solve the equation by finding the square roots
w^2-36=-64

X - 6 - 8 = -19 + x
Answer: infinite solutions, one solution, zero, no solution
Answer:
No solution.
Step-by-step explanation:
[tex]x-6-8=-19+x[/tex]
Subtract x from both sides:
[tex]x-6-8-x=-19+x-x[/tex]
[tex]-6-8=-19[/tex]
[tex]-14=-19[/tex]
Since both sides are not equal, there is no solution.

Write an equation in slope intercept form for the line that has a slope of -4 and passes through the point (1,2)
Answer:
y=-4x+6
Step-by-step explanation:
what you have to do for this problem you have take the point 1,2 slide it over to the left one since the slope is negative and up 4 then you do that till you cross the y axis, but in this case you only have to do it once
