2) What is 18th term in this sequence: 45, 49, 53, 57,
Answer:
a₁₈ = 113
Step-by-step explanation:
There is a common difference d between consecutive terms
d = 49 - 45 = 53 - 49 = 57 - 53 = 4
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 45 and d = 4, then
a₁₈ = 45 + (17 × 4) = 45 + 68 = 113

Answer:
The answer required in ratio is: b:c = 9:8
Step-by-step explanation:
We are given:
The ratio a:b = 2:3 and the ratio a:c = 3:4
We need to find the ratio b:c
a:b=2:3 can be written as:
[tex]\frac{a}{b}=\frac{2}{3}[/tex]
Finding value of a by cross multiplying:
[tex]\frac{a}{b}=\frac{2}{3}\\3a=2b\\a=\frac{2b}{3}[/tex]
a:c = 3:4 can be written as: [tex]\frac{a}{c}=\frac{3}{4}[/tex]
Putting value of a and finding b:c
[tex]\frac{a}{c}=\frac{3}{4}\\Put\:a=\frac{2b}{3}\\\frac{2b}{3}}\times \frac{1}{c}=\frac{3}{4} \\Finding\:value\:of\:b/c\\\frac{b}{c}=\frac{3\times 3}{4 \times 2}\\ \frac{b}{c}=\frac{9}{8}[/tex]
So, we get the value of [tex]\frac{b}{c}=\frac{9}{8}[/tex]
The answer required is in ratio so: b:c = 9:8

Find rhe equation of the graphed line.
a. y = -x -6
b. y = x + 6
c. y = x - 6
d. y = -x + 6
Answer:
c. y = x - 6
Step-by-step explanation:
This question wants you to find the equation in slope-intercept form, each is y=mx+b, where m is the slope and b is the y-intercept. The first thing to do is find the y-intercept, to do this find the value of y when x equals zero. The way to do this is to look the value of y on the y-axis. In this case, the y-intercept is -6. Then, find the slope; since you are given the graph you can count out the slope. To do this find out how much the y and x values change. On this graph, y increases 1 when x increases 1, so the slope is 1/1 or one 1. So the equation is y=1x-6, which simplifies to y=x-6.

it takes 10.4 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 9 students and observed that they had a mean of 10.7 hours with a variance of 1.44. A level of significance of 0.1 will be used to determine if the technique performs differently than the traditional method. Assume the population distribution is approximately normal. Find the value of the test statistic. Round your answer to three decimal places.
Answer:
Test statistic (t) = 0.625
Step-by-step explanation:
Step(i):-
mean of the Population(μ) = 10.4 hours
Sample mean (x⁻) = 10.7 hours
Standard deviation of the sample( S) = 1.44
The level of significance (α= 0.1
Sample size 'n' = 9
Degrees of freedom = n-1 = 9-1 =8
Step(ii):-
Test statistic
[tex]t = \frac{x^{-} -mean}{\frac{S}{\sqrt{n} } }[/tex]
[tex]t = \frac{10.7 -10.4}{\frac{1.44}{\sqrt{9} } } =0.625[/tex]

Anne has 5 pints of milk and is planning to make 6 cakes to sell in fundraising. Each cake will require 112 cups of milk. Does she have enough milk to make the 6 cakes? If so, how many cups of milk will be left, and if not, how many extra cups of milk would she need?
Yes she has enough milk; She will have 1 extra cup of milk.
No she does not have enough milk; She will need 1 more cup of milk.
Yes she has enough milk; She will have 112 extra cups of milk.
No she does not have enough milk; She will need 412 extra cups of milk.
Answer:
Option (1)
Step-by-step explanation:
Each cake requires cups of milk = [tex]1\frac{1}{2}[/tex] cups ≈ 1.5 cups
6 cakes will require milk = 6 × 1.5
= 9 cups
Anne has milk = 5 pints
∵ 1 pint = 2 cups
∴ 5 pints = 10 cups
Therefore, Anne has milk = 10 cups
Extra amount of milk Anne has = 10 - 9 = 1 cup
Hence, Answer is yes, she has enough milk. She will have 1 extra cup of milk.
Option 1 will be the answer.
through: (-9, 0), perpendicular to
y = 3x - 2
In slope intercept form
Answer:
The equation perpendicular to y = 3x - 2 and passing through (-9, 0) in the slope-intercept form will be:
[tex]\:\:y\:=-\frac{1}{3}x-3[/tex]Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the line
y = 3x - 2
comparing with the slope-intercept form of the line equation
The slope of the line y = 3x - 2 is: m = 3
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = 3
Thus, the slope of the the new perpendicular line = – 1/m = -1/3 = -1/3
The point-slope form of the line equation is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = -1/3(x₁, y₁) = (-9, 0)now substituting the perpendicular slope m = -1/3 and (-9, 0) in the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-0=-\frac{1}{3}\left(x-\left(-9\right)\right)[/tex]
[tex]y=-\frac{1}{3}\left(x-\left(-9\right)\right)[/tex]
[tex]y=-\frac{1}{3}\left(x+9\right)[/tex]
[tex]\:\:y\:=-\frac{1}{3}x-3[/tex]
Therefore, the equation perpendicular to y = 3x - 2 and passing through (-9, 0) in the slope-intercept form will be:
[tex]\:\:y\:=-\frac{1}{3}x-3[/tex]Noah and Lin are each trying to solve the equation x^2-6x+10=0.They know that the solutions to x^2=-1 are i and -i but they are not sure how to use this information to solve for x in their equation.Lin knows 36-40 is a negative number and isn’t sure what to do next. Show how Lin can write her solution using i.
Lin's work:
Answer:
x=3+i or x=3-i
Step-by-step explanation:
x²-6x+10=0
(x²-6x+9) + 1 = 0
(x-3)² + 1 = 0
(x-3)² = -1
x-3 = ± √-1 = ± i
x = 3 + i or x = 3 - i
The next step is that L in can write her solution using i be like x = 3 + i or x = 3 - i.
What is an equation?Mathematical phrases with two algebraic symbols on either end of the equal (=) sign are called equations. To illustrate this connection, the expressions just on the left and right are demonstrated to be equivalent to each other. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
From the given values provided in the question,
x² - 6x + 10 = 0
(x² - 6x + 9) + 1 = 0
(x - 3)² + 1 = 0
(x - 3)² = -1
x - 3 = ±√-1
x - 3 = ± i
x = 3 + i or,
x = 3 - i

A house that is 30 feet tall casts a shadow that is 50 feet long. A nearby tree casts a shadow that is 75 feet long. HOW LONG IS THE TREE?
Answer:
the tree would be 45 feet tall
Step-by-step explanation:
so the house is 30 feet and 50 feet shadow, if you divide by 2 you can see that every 15 feet gives a 25 foot shadow, since 75-50 is 25 so in turn if the tree is 45 feet tall, it will make 75 foot shadow
