Answer:
[tex]y = \frac{1}{6}x - 4[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
[tex]y = \frac{1}{8}x[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
[tex]y = 12x - 9[/tex]
Step-by-step explanation:
Required
Represent in gradient intercept form
This means that the equation be in form: [tex]y = mx + c[/tex]
Solving (a): [tex]3y = \frac{1}{2}x - 12[/tex]
Divide through by 3
[tex]\frac{3y}{3} = \frac{1}{3*2}x - \frac{12}{3}[/tex]
[tex]y = \frac{1}{6}x - 4[/tex]
Solving (b): [tex]5x = 10y - 20[/tex]
Make y the subject
[tex]10y = 5x + 20[/tex]
Divide through by 10
[tex]y = \frac{5x}{10} + \frac{20}{10}[/tex]
[tex]y = \frac{x}{2} + 2[/tex]
Solving (c): [tex]x = 8y[/tex]
Make y the subject
[tex]8y= x[/tex]
Divide through by 8
[tex]y = \frac{1}{8}x[/tex]
Solving (d): [tex]\frac{1}{2}x = 3y - 2[/tex]
Make y the subject
[tex]3y = \frac{1}{2}x+ 2[/tex]
Divide through by 3
[tex]y = \frac{1}{2*3}x+ \frac{2}{3}[/tex]
[tex]y = \frac{1}{6}x+ \frac{2}{3}[/tex]
Solving (d): [tex]\frac{2}{3}y - 8x = -6[/tex]
Make y the subject
[tex]\frac{2}{3}y = 8x -6[/tex]
Divide through by 3/2
[tex]\frac{3}{2} * \frac{2}{3}y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * ( 8x -6)[/tex]
[tex]y =\frac{3}{2} * 8x -\frac{3}{2} * 6[/tex]
[tex]y = 3 * 4x - 3 * 3[/tex]
[tex]y = 12x - 9[/tex]
Great Falls is at approximately 47.5 degrees N, and 111.3 degrees W. Lemhi is approximately 45.5 degrees N, and 113.5 degrees W. (We will assume the rivers flow straight from Great Falls to Lemhi on the surface of Earth). Apply the Law of Cosines for Sides of a spherical triangle to find the angle between Great Falls and Lemhi.
Answer:
The angle between Great Falls and Lemhi is approximately 3.02°
Step-by-step explanation:
The location parameters are;
The Great Falls location = 47.5° N, 111.3° W
The location of Lemhi = 45.5 °N and 113.5 °W
Therefore, we have;
The angle between the Great Falls and the poles, AP = 90° - 47.5° = 42.5°
The angle between Lemhi and the poles, PB = 90° - 45.5° = 44.5°
The angle between the lines of longitude, P = 113.5° - 113° = 0.5°
By the law of cosines for Sides of a spherical triangle, we have;
CosAB = cos AP·cosPB + sinAP·sinPB·cosP
Where;
AB = The angle between Great Falls and Lemhi
∴ CosAB = cos(47.5°) × cos(44.5°) + sin(47.5°) × sin(44.5°) × cos(0.5°) ≈ 0.9986
AB ≈ arccos(0.9986) ≈ 3.02°
The angle between Great Falls and Lemhi ≈ 3.02°

Answer:
340 quarters1020 dimes1031 nickels2062 penniesStep-by-step explanation:
x is the number of quarters
__
a) d = 3x . . . . . . the number of dimes is 3 times the number of quarters
b) n = d + 11 = 3x +11 . . . . there are 11 more nickels than dimes
c) p = 2n = 2(3x +11) = 6x +22 . . . . there are twice as many pennies as nickels
d) The total number of coins is ...
x + d + n + p = 4453
x + (3x) +(3x +11) +(6x +22) = 4453
13x +33 = 4453
13x = 4420
x = 4420/13 = 340 . . . . number of quarters collected
3x = 1020 . . . . . . . . . . . .number of dimes collected
1020 +11 = 1031 . . . . . . . number of nickels collected
2·1031 = 2062 . . . . . . . . number of pennies collected
There were 340 quarters, 1020 dimes, 1031 nickels, and 2062 pennies collected.
_____
Check
340 +1020 +1031 +2062 = 4453 . . . as required
The design for a small counter top
is shown. What is the perimeter and
area of the counter top?
Answer:
P = 22 ft
A = 18 ft²
See picture
Step-by-step explanation:
The perimeter is all the sides added together. You have to find the missing values. The missing vertical value is 2.5 (4-1.5). The missing horizontal value is 4 (7-3).
Add all the sides together for the perimeter.
Split the shape into 2 rectangles to find the area. Find the area of each rectangles, then add them together to find the total area.

Factorise the following.
Answer:
iii. (p - 7)(p - 3)
iv.(x - 8)(x + 4)
Step-by-step explanation:
iii. p² - 10p + 21
= p² - (7 + 3)p + 21
= p² -7p -3p + 21
= p(p - 7) - 3(p - 7)
= (p - 7)(p - 3)
iv. x² - 4x - 32
= x² - (8 - 4)x - 32
= x² - 8x + 4x - 32
= x(x - 8) + 4(x - 8)
= (x - 8)(x + 4)

A sample of six repair records for a different type of fiber optic component was drawn. The repair costs, in dollars, were as follows. 93 97 27 79 81 87 Would it be appropriate to compute a 95% confidence interval for the population standard deviation of the costs
Answer:
The answer is "This is the right thing. There might be a surface sample which indicates that the population is not regular".
Step-by-step explanation:
When the community is ordinary or a biosensor, a normal distribution could be calculated for the dependent variable. Data shows chi-squared distributions of n-1 degrees - of - freedom about the dependent variable.
Chi-square was its precise outcome for the data set, while chi-square is a close estimate for non-normal information. So, we should also calculate CI for uncommon information. Throughout the case of an outlier, however, data refers to non because as mean tends to move in a skewed direction to the outer surface.

The radius of a circular disk is given as 24 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate the maximum error in the calculated area of the disk. (Round your answer to two decimal places.) cm2 (b) What is the relative error
Answer:
9.60πcm²
Step-by-step explanation:
Area of circular disk, A = πr²
Differntiate A with respect to r
dA/dr = π * (2r^(2-1)) /(2-1) + C
dA/dr = π * 2r/1
dA/dr = 2πr
dA = 2πr * dr
dA = 2πrdr
dA = maximum error ; dr= Error in measurement = 0.2 cm ; r = radius = 24cm
dA = 2π * 24 * 0.2
dA = 9.60πcm²

Raul's hunting club membership costs $130 plus $45 per month. Which equation represents the cost of membership for x months?
Answer:
[tex]y = 130 + 45x[/tex]
Step-by-step explanation:
Given
[tex]Base = 130[/tex]
[tex]Monthly = 45[/tex]
Required
The cost for x months
Represent this cost with y.
So:
[tex]y = Base + Monthly * x[/tex]
[tex]y = 130 + 45 * x[/tex]
[tex]y = 130 + 45x[/tex]
