write the equation of the line that passes through the points (-1, 2) and (6,3) in slope-intercept form
Answer:
y=(1/7)*x+(15/7)Step-by-step explanation:
first, lets find the slope:
m=(y2-y1)/(x2-x1)
m=(3-2)/(6-(-1))
m=1/7
y=(1/7)*x+b
to find b lets pug in a point we know into the equation:
3=(1/7)*6+b
21/7=6/7+b
b=(21/7)-(6/7)
b=15/7
now we know the equation in slope intercept form representing this function is:
y=(1/7)*x+(15/7)
Answer:
y= 1/7x+15/7
Step-by-step explanation:
points
(-1, 2) and (6, 3)
slope intercept form:
y= mx+b2= -m+b, 3= 6m+b ⇒ m= 1/7 ⇒ b= 2 1/7= 15/7
y= 1/7x+15/7OBC is a sector of a circle with centre o and radius 9cm work out the area of the shaded region as a percentage of the area of sector obc to 1 decimal place
Answer:
83.7 %
Step-by-step explanation:
To get the area of the shaded region, we will following these steps.
Step one: Get the area of the sector of the circle.
The area of the sector of the circle can be obtained using the formula:
[tex]Area = \frac{\theta}{360}\times \pi r^{2}[/tex]
Theta will be 60 degrees because triangle OAD is an equilateral triangle
Hence, [tex]Area = \frac{60}{360}\times \pi \times 9^{2}= 42.42cm^{2}[/tex]
Step Two: Get the area of the equilateral triangle
The area of the equilateral triangle can be got using the formula
[tex]Area = \frac{1}{2} Base \times Height[/tex]
The height of the triangle can be got by drawing an imaginary line bisecting the triangle into two parts and applying the Pythagoras' theorem to any of the resulting right-angled triangles formed.
This will be [tex]height =\sqrt{4^{2}-2^{2}} =3.46cm[/tex]
Thus [tex]Area = \frac{1}{2}\times 4\times 3.46=6.93cm^{2}[/tex]
Step Three: Subtract the area of the triangle from the area of the sector
Area of the shaded portion = [tex]42.42cm^{2}-6.93cm^{2}=35.49cm^{2}[/tex]
Step Four: Divide the area of the shaded portion by the area of the entire shape and multiply the result by 100:
Expressing the ratio of the two areas as a percentage, we have
[tex]\frac{35.49}{42.42} \times 100\approx 83.7 %[/tex] %

Which inequality is represented by this graph?
Answer: C
Step-by-step explanation:
We can say that the equaiton of the line is -1/6x+1, considering that is in each answer choice. Than main part is the shading and inequality. If you look closely at the graph, the shading line is a dashed/dotted line. This means the shaded part does not equal the actual line. We can eliminate B and D.
Now, we are left with A and C. A is saying y< while C is saying y>. C is the correct answer because if you look at the shading, it it above the line, which is greater than. Therefore, the answer is C.
Describe fully the single transformation that maps triangle a onto triangle b
Answer:
Triangle (A) reflected over the line y = x
Step-by-step explanation:
From the figure attached,
Coordinates of the vertices of triangle (A) are A(1, 4), B(1, 2) and C(2, 2)
After transformation of triangle A, coordinates of the vertices A', B' and C' of the image triangle (B) are,
A'(4, 1), B'(2, 1) and C'(2, 2)
Lets choose point A to find the rule of transformation,
A(1, 4) → A'(4, 1)
Rule → (x, y) → (y, x)
It shows triangle (A) has been reflected across a line y = x.
Therefore, triangle (A) maps onto triangle (B) when reflected over the line y = x.
Write a rule for the following
Input Output

Telephone pole breaks and falls as shown. To the nearest foot, what was the
original height of the pole? they are 7 ft and 10 ft pls explain how u got the answer and the choices r a.19ft. b.17ft. c.20ft. d.18 ft pls find the answer for me
but its a triangle and in the bottom it has number 10 and in the long side of the triangle is 7
Answer:
Length of the pole = 12.2ft
Step-by-step explanation:
Hello,
According to your description, the pole against a wall of height 7ft and the distance between the base of the pole to the wall is 10ft.
See attached document for better illustration.
To solve this problem, we'll have to make use of pythagorean theorem
According to pythagorean theorem,
X² = y² + z²
X = ?
Y = 10ft
Z = 7ft
X² = 10² + 7²
X² = 100 + 49
X² = 149
X = √(149)
X = 12.2ft
The length of the pole is 12.2 ft
Unfortunately, the length of the pole does not corresponds with any of the answers above, but this is actually the right answer.
Good luck
The scores for a state's peace officer training test are normally distributed with a mean of 55 and a standard deviation of 12. The test scores range from 0 to 100. A state agency will only interview applicants with test scores of 43 or greater. About what percent of the people have test scores that make them eligible to be interviewed?
Answer:
About 84% of the people have test scores that make them eligible to be interviewed
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
[tex]\mu = 55, \sigma = 12[/tex]
A state agency will only interview applicants with test scores of 43 or greater. About what percent of the people have test scores that make them eligible to be interviewed?
This is 1 subtracted by the pvalue of Z when X = 43. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{43 - 55}{12}[/tex]
[tex]Z = -1[/tex]
[tex]Z = -1[/tex] has a pvalue of 0.1587
1 - 0.1587 = 0.8413
Rounding to the nearest percent
About 84% of the people have test scores that make them eligible to be interviewed

Step-by-step explanation:
11.4-15.7 = -4.3
Answer:
A. -4.3 F
Step-by-step explanation:
Originally you started with 11.4 F, and the question said it decreased by 15.7 F so that basically means you subtract the final condition from initial,
11.4 F - 15.7 = -4.3 F, so at night it was -4.3 F cold.
If you think about this question in terms of apples. Originally I gave you 12 apples to keep for a day. When I returned home at 7pm the numbers of apples decreased by 8. So bascially my final apples will be 12- 8 = 4 apples remaining.

I need to know the answer for “x” please!
Answer:
x r 1.26 cm
Step-by-step explanation:
This can easily be solved by congruence.
Both triangles have the same proportions.
9.8 : 8.8 = (2 + 9.2) : (x + 8.8)
Because these are proportional, we can use and write this as if they were fractions.
9.8 / 8.8 = (2 + 9.2) / (x + 8.8)
multiply crosswise, gives:
9.8 * (x + 8.8) = (2 + 9.2) * 8.8
9.8 * x + 9.8 * 8.8 = (11.2) * 8.8
9.8 * x + 86.24 = 98.56
9.8 * x = 98.56 - 86.24
9.8 * x = 12.32
Divide left and right of the = sign by 9.8 gives,
x = 12.32 / 9.8
x = 1.2(571428)
x = 1.26 cm

Answer:
Step-by-step explanation:
Firstly,
What is the mean?
The mean is where you add up all the number then divide the total by how many numbers there are.
8th number?
1.4.1
2. 5.7
3. 6.1
4. 2.3
5. 3.1
6. 4.5
7. 4.1
8. x
Opposite way:
4.1 + 5.7 + 6.1 + 2.3 + 3.1 + 4.5 + 4.1 = 29.9
(29.9 x) / (8) = 3.7375
3.7375 + x = 4.1375
4.1375 - 3.7375 = 0.4

Answer:
AB = 3.5 cm
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular face and h the length of prism )
Here V = 84 and h = 12 , thus
12A = 84 ( divide both sides by 12 )
A = 7 ← area of Δ ABC
Thus
[tex]\frac{1}{2}[/tex] × 4 × AB = 7
2AB = 7 ( divide both sides by 2 )
AB = 3.5 cm

Answer:
The cost per duck is $5.00 and $8.00 for chickens
Step-by-step explanation:
The equation would be like this:
50c + 30d = 550 (divide this by 10)
5c + 3d = 55
3d = 55 - 5c (multiply by 3)
9d = 165 - 15c
Next,
44c + 36d = 532 (divide this by 4)
11c + 9d = 133
11c + 165 - 15c = 133
11c - 15c = 133 - 165
-4c = -32 (divide by -4)
c = 8
Therefore, the cost of each chicken is $8.00
9d = 165 - 15c
9d = 165 - 15(8)
9d = 165 - 120
9d = 45 (divide by 9)
d = 5
