Given points (-3;-6), G(3; -2) and H(6; 1); determine:
(a) The equation of line FG
Answer:
The equation of line FG is [tex]y = \frac{2}{3}x - 4[/tex]
Step-by-step explanation:
Equation of a line:
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which m is the slope and b is the y-intercept.
F(-3;-6), G(3; -2)
When we have two points, the slope is given by the change in y divided by the change in x. So
Change in y : -2 - (-6) = -2 + 6 = 4
Change in x: 3 - (-3) = 3 + 3 = 6
Slope: [tex]m = \frac{4}{6} = \frac{2}{3}[/tex]
So
[tex]y = \frac{2}{3}x + b[/tex]
Finding b:
(3; -2) means that when [tex]x = 3, y = -2[/tex]. We use this to find b.
[tex]y = \frac{2}{3}x + b[/tex]
[tex]-2 = \frac{2}{3}(3) + b[/tex]
[tex]2 + b = -2[/tex]
[tex]b = -4[/tex]
The equation of line FG is [tex]y = \frac{2}{3}x - 4[/tex]

Answer:
(c) x = 10
Step-by-step explanation:
The diagonals of a square cross at right angles, so the measure of angle KNJ is 90°.
90 = 10x -10
100 = 10x . . . . . add 10
10 = x . . . . . . . . divide by 10
The value of x is 10.

rule for 15,19,23 please I need it urgently
Answer:
[tex]a_{n}[/tex] = 4n + 11
Step-by-step explanation:
There is a common difference between consecutive terms, that is
19 - 15 = 23 - 19 = 4
This indicates the sequence is arithmetic with explicit rule
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 15 and d = 4 , then
[tex]a_{n}[/tex] = 15 + 4(n - 1) = 15 + 4n - 4 = 4n + 11

The function g is a transformation of f. If g has a y-intercept at 4, which of the following functions could represent g?
g(x) = f(x) - 2
g(x) = f(x + 2)
g(x) = f(x) + 4
O g(x) = f(x-4)
Answer:
g(x) = f(x) - 2
g(x) = f(x + 2)
Step-by-step explanation:
y-intercept of a function:
The y-intercept of a function is the value of y when x = 0.
Function f:
Graph given in this question
When [tex]x = 0, y = 6[/tex], so the y-intercept is 6.
Additionally, when [tex]x = -2, y = 4[/tex]
If g has a y-intercept at 4, which of the following functions could represent g?
Either we subtract 2 from f, that is:
[tex]g(x) = f(x) - 2[/tex]
Or we can also add 2 on the domain, that is, moving 2 units to the right, so:
[tex]g(x) = f(x+2)[/tex]
So the first two options are correct.
Answer:
the answer would be g(x)=f(x)-2

What is a probability ?
A number that measures the likelihood that the event will occur.
An activity involving chance in which results are observed
An observation of an experiment
The result of an experiment
Answer:
A number that measures the likelihood that the event will occur.
Step-by-step explanation:
Probability is a measure of the frequency of occurrence of a phenomenon, the value of which can be expressed qualitatively or quantitatively. Probability is quantified as a real number between 0 and 1, although sometimes probability is also expressed as a percentage. The probability is 0 when the event cannot or will never happen, and the probability is 1 when it happens for sure or it always happens. If the probability is between these values, the event is not common and its occurrence is uncertain. The higher the probability value, the more common the event is or the more certain it will occur.
A cargo plane has a maximum take off weight of 910000 pounds which expression can be used to determine the maximum take off weight in tons?
Answer:
910,000 ÷ 2,000
Step-by-step explanation:
1 ton = 2000 pounds
therefor divide pounds by 2000 to get tons
910,000 ÷ 2,000
The volume of a sphere is 905 1/7 cm³ ? Determine its diameter
will give brainliest
Volume of the sphere = 4/3πr³
905 1/7 = 4/3*22/7*r³
6336/7 = 4/3*22/7*r³
r³ = (6336*7*3)/(4*22*7)
r³ = 133056/616
r³ = 216
r = ∛216
r = 6 cm
So, diameter = 6*2 = 12 cm
Surface area of the sphere = 4πr²
= 4*22/7*6*6
= 3168/7
Surface area of the sphere = 452.57 sq cm

9514 1404 393
Answer:
a4 = -666
Step-by-step explanation:
Use the recursive definition repeatedly.
a1 = 6
a2 = -5(6) +4 = -26
a3 = -5(-26) +4 = 134
a4 = -5(134) +4 = -666

Use the formula v = IR for current flowing through a resistor, where V is the voltage in volts, I is current in amps, and R is resistance in ohms. Find the current through a resistor with resistance 15 ohms if the voltage across it is 3 volts.
Answer:
0.2 amps
Step-by-step explanation:
Given data
The formula V=IR is the formula for ohms law
Which state that the voltage is directly proportional to the current and the resistance in an electric circuit
Now
R= 15 ohms
V= 3volts
V= IR
3= I*15
I= 3/15
I= 0.2 amps
Hence he current flowing is 0.2 amps

The product of 7 , and a number increased by 8 , is 105. What is the number?
Answer:
97
Step-by-step explanation:
Which function is continuous across its domain?
Answer:
B.
Step-by-step explanation:
a function is continuous, if the functional values are the same at the "connection" points of the various segments (and the segments themselves are continuous).
"continuous" simply means that the graph of the function is a continuous line without any "rips". it can have corners and such, but no "interruptions".
specifically it means : for every possible y value in the defined range of the function there is an x value that causes this y.
all defined segments are continuous functions.
so, let's look at
A. the first connection point is x=-2.
-2 + 6 = 0.5×(-2)²
4 = 0.5×4 = 2
4 = 2 is wrong. => here, at this point, the function "rips" apart and is not continuous.
B. x=-2
-2 + 4 = 0.5×(-2)²
2 = 2 is correct. continuous at this point.
second connection point x=4
0.5×4² = 20 - 3×4
0.5×16 = 20 - 12
8 = 8 is correct. continuous at this point
C. x=-2
-2 - 2 = 0.5×(-2)²
-4 = 2 is wrong. not continuous
D. x=-2
-2 + 4 = 0.5×(-2)²
2 = 2 is correct. continuous here.
now for x=4
4 + 4 = 25 - 3×4
8 = 25 - 12 = 13
8 = 13 is wrong. not continuous.

Graph the following inequality. Then click to show the correct graph.
3x - 2y ≤ 6
Answer:
We want to graph the inequality:
3x - 2y ≤ 6
The first step is to write this as a linear equation, to do it, we can isolate y in one side of the inequality.
3x ≤ 6 + 2y
3x - 6 ≤ 2y
(3/2)x - 6/2 ≤ y
(3/2)x - 3 ≤ y
or:
y ≥ (3/2)x - 3
Because we have the symbol ≥
The points on the line are solutions, then the first part is to graph the line:
y = (3/2)*x - 3
Next, we have:
y equal to or larger than (3/2)*x - 3
Then we need to shade all the region above that line.
The graph can be seen below.
A father and his son decide to sum their ages. The sum is equal to sixty years. Six years ago, the age of the father was five times the age of his son. Six years the son's age will be?
I will mark as brainlist plzzzzz
Solve the question I know the answer but i cannot solve it..
I can tell you that ans is 16.8 years but solve...
Answer:
20
Step-by-step explanation:
Let father's age be x
let son's age be y
x + y = 60 - (eq 1)
Six years ago,
(x - 6) = 5(y - 6) -(eq 2)
From (1)
x = 60-y
Therefore, 60-y - 6= 5y - 30
y = 14
in six years, y = 20

Can someone please help me
Answer:
8,889
Step-by-step explanation:
1 twig = 10 leaves
1 branch = 10 twigs = 100 leaves
1 trunk = 10 branches = 1000 leaves
1 tree = 10 trunks = 10,000 leaves
The complete tree has 10,000 leaves
The woodcutter cut off:
1 trunk = 1000 leaves
1 branch = 100 leaves
1 twig = 10 leaves
1 leaf
Total number of leaves that were cut:
1000 + 100 + 10 + 1 = 1111
Leaves left on tree:
10,000 - 1,111 = 8,889
A professor wants to estimate the average time it takes his students to finish a computer project. Based on previous evidence, he believes that the standard deviation is approximately 3.6 hours. He would like to be 96% confident that his estimate is within 5 hours of the true population mean. Use RStudio to determine how large of a sample size is required without rounding any interim calculations.
Answer:
A sample size of 3 is required.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.96}{2} = 0.02[/tex]
Now, we have to find z in the Z-table as such z has a p-value of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.02 = 0.98[/tex], so Z = 2.054.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Based on previous evidence, he believes that the standard deviation is approximately 3.6 hours.
This means that [tex]\sigma = 3.6[/tex]
He would like to be 96% confident that his estimate is within 5 hours of the true population mean. Use RStudio to determine how large of a sample size is required without rounding any interim calculations.
The sample size needed is of n, and n is found when M = 5. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]5 = 2.054\frac{3.6}{\sqrt{n}}[/tex]
[tex]5\sqrt{n} = 2.054*3.6[/tex]
[tex]\sqrt{n} = \frac{2.054*3.6}{5}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.054*3.6}{5})^2[/tex]
[tex]n = 2.19[/tex]
Rounding up:
A sample size of 3 is required.
